china safety valve quotation

If you have ever looked through my introduction articles about Chinese valves. There is one thing in common that I always share in those articles, that China is one of the countries. It is possible to manufacture almost all industrial valves worldwide. The price is only half that of brands from other countries. And China gate valve is also one of those products. Right now, let"s see together, what the Chinese gate valve has and has not done well at any point. But why is the price of the valve so cheap.

First I will mention the structure of the valve, the following information you can apply to all lines gate valve difference. Sometimes there is only a slight difference in the material and design with or without sleeves. Overall, not too much of a difference.

Valve body: Like any valve, the body is considered an extremely important part. If the body does not meet the technical and quality requirements. It is very difficult to put the valve into service for a long time.

Impeller: To create a complete and openable gate valve. Then indispensable part called vane, placed inside the body and connected to the valve shaft. Whether the valve opens or closes depends entirely on the valve disc.

Ty valve: for ty, also known as shaft, is always made from stainless steel regardless of what material the valve is made of. The shaft also only uses a single material to manufacture. For ty, there are floating and sinking.

Controller: The controller is using a gate valve, which can be a handwheel or an electric unit. These are two very different schools of operation. I will analyze these two cases in more detail in a moment.

Whether using a manual or an electric unit, the ultimate purpose is only to raise the valve disc up or down. When the valve is in the fully closed state. The valve disc will be lowered to the lowest. Together with the stem create absolute tightness, not allowing flow to flow from one side to the other end of the valve.

When we want to open the valve, we just need to apply force to the handwheel, pay attention that the direction of rotation must be counter-clockwise. Then the new valve starts to switch from closed state to stay. If it"s open and you turn it clockwise, you can"t turn it even if you try hard.

Above is the most basic information of China gate valve. If you still want more information about the valve. We invite you to read the following presentations.

In the structure I mentioned, the valve shaft is an indispensable part for the gate valve. Currently, China gate valves have two separate installation styles for valve tyres. We invite you to take a look at the introduction below.

The Chinese gate valve is a type of valve, you cannot see the valve shaft. So where is the valve shaft? Or do not need to use the shaft anymore. All of these assumptions are incorrect.

For the submerged type, the valve stem is located in the body, one end is connected to the handwheel. The other end is connected to the valve disc. There is a special thing that, at the end of the shaft that connects to the valve disc, it will be threaded. When rotating, the valve disc will follow the thread foot and move up and down.

China floating gate valve is the reverse product to the submersible series. Why is it called a floating valve, because now the valve stem will be placed on top. One part is sunk into the body, the rest is exposed. Simply put, it will be higher than the valve body.

The second identifying feature of the floating Chinese gate valve. When open, the valve stem will be higher than the handwheel, when the valve is closed, the valve shaft will be horizontal with the handwheel.

Cast iron gate valve is the most used product, ViVa industrial equipment engineering joint stock company. Importing Chinese cast iron gate valves three times a year. Especially the green cast iron lines, then with the black cast iron lines.

For cast iron is a material that is only durable when you use it in the most reasonable way. With cast iron you are never allowed to use chemicals, or steam systems with heat up to several hundred degrees Celsius. This will directly affect the valve"s life very quickly. Water will be the most suitable medium to use. Because I am afraid that people will use it incorrectly, I will classify it for everyone to understand each part.

If you need better quality valves, more media may be needed. There is no other way you have to use the Chinese stainless steel gate valve. Accept a higher price, to get what other lines never do.

China stainless steel gate valve, made from three types of materials that are: stainless steel 201, 304, 316. With each type of material will have different quality and price. These two things go hand in hand and are proportional to each other in every product. Not only the stainless steel gate valve.

How to operate I will not refer to operating the crank. Since the handwheel is the default closing method, most of us know it. We are only interested in new products and few users. If you need to use it, read on to understand what advantages the Trung Quoc gate valve brings to us.

Using voltage to open and close, instead of human health. Especially in case, the working environment is too deep, harmful to health, the electric gate valve is an extremely reasonable choice. The voltage used is only 220V, do not use the 24v type like ball valves or butterfly valves.

The Chinese gate valve has a lot of different advantages, I will only mention the most important points. It greatly affects the usage process. When you understand, you also know how to operate to maximize the advantages of the valve.

The valve body is machined firmly, always bringing stability when in use. Same size together, gate valves are always larger than butterfly or ball valves.

The size, whether large or small, does not affect the opening and closing process. Whether you open one valve DN50 or five DN500, you can hardly feel the difference.

China gate valves have many different products, this has been shown by me above. To end this article today, I will add a bit more pricing. Although it is not in the valve information too much, it is the most interested. This is not too strange, when shopping, everyone wants to buy the best quality product at a reasonable price.

China butterfly valve price, will depend on the size. Usually size DN100= 245.000, for more other sizes. You can contact me directly. Phone number for quotation 0349 775 318.

Safety valve is a valve mechanism which instantly releases a substance from a boiler, pressure vessel, or any other system, once the pressure or temperature exceeds preset limits.It is among a group of pressure safety valves (PSV) or pressure relief valves (PRV), that also includes relief valves, safety relief valves, pilot-operated relief valves, low pressure safety valves, and vacuum pressure safety valves.Safety valves were first utilized on steam boilers throughout the Industrial Revolution. Early boilers operating without one were vulnerable to accidental explosion.Vacuum safety valves (or combined pressure/vacuum safety valves) are utilized to prevent a tank from collapsing even though it is being emptied, or when cold rinse water can be used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures.

When sizing a vacuum safety valve, the calculation technique is not defined in almost any norm, especially in the hot CIP / cold water scenario, however, many manufacturers allow us sizing simulations.

Because of different of drive source, SSV can dividedinto Hydraulic safety valve and pneumatic valve ; With thermal and high voltage explosion-proof device ; Actuators and prepare two parts of the valve, standard interface, easy replacement and maintenance .

This valve is used for power plant boilers, pressure containers, pressure and temperature reducing device and other facilities. It serves to prevent the pressure exceeding the highest allowable pres-sure value and ensure the safety of the device when working.

（1）The pressure of the disc is balanced through the lever and heavy hammer and the valve is ensured seal by moving the for ton of heavy hammer and changing the weight of heavy hammer to reach the required set pressure.

（3）At the top of valve is equipped an electromagnet to open and another to close the valve. The actions of the mechanism and the electric appliance are separate and will not affect each other.

（2）Impulse safety valve shall be installed vertically and the lever shall be kept level. The clearance from the lever to both sides of guide fork shall be even.

（4）A long distance between the leading pipe of the impulse safety valve and the inlet pipe of the main safety valve shall be kept. And the distance between the electric contact pressure meter and the inlet pipe of the main safety valve shall be no less than 5 times of the diameter of the inlet pipe, for feat that the validity of the mater and the impulse safety valve may be affected by the steam releasing process of the main safety valve.

This valve is used for power plant boilers, pressure containers, pressure and temperature reducing device and other facilities. It serves to present the pressure exceeding the highest allowable pres-sure value and ensure the safety of the device when working.

1,When the medium pressure rises to the set pressure, the in-pulse safety valve opens, and the medium in the impulse pipe enters into the piston chamber of the main safety valve from impulse pipe, forcing the piston to descend, and then the valve automatically open-s; when the impulse safety valve closes, the disc will slash automatically close.

2,The main safety valve shall be fastened upon the gallows, which sustains the back-seat force produced in the steam discharging process of the main safety valve.

3,The exhaust pipe shall contain a special gallows to prevent the force of its weight directly applying on the main safety valve. The connecting Lange At the lowest point of the exhaust pipe, water drainage shall be taken into consideration to avoid producing water hammer while discharging set between the main safety valve and exhaust pipe shall eliminate any extra stress.

Valve is used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. It is widely used in many industries such as petroleum, water, natural gas, chemical industry, food, pharmaceuticals, etc. It belongs to standard parts, so-called standard parts It means that there are prescribed sizes, and standards represent principles, and mostly the material is steel. It represents fortitude. In 15 years working, I slowly honed a strong and principled personality like a valve. And after having a lovely son, I became more mature, meticulous, and patient.
