boiler drum safety valve pricelist

(2) When the safety valve is used to discharge flammable liquid, the outlet of the safety valve should be connected with the accident tank. When the discharged material is high temperature combustible, the receiving container should have corresponding protective facilities.

(3) General safety valves can be vented in situ. The vent should be higher than 1 m (m) of the operator and should not be directed towards the open flame location, spark emission location and high temperature equipment within 15 m (m). The safety valve vent of indoor equipment and containers should lead out the roof and be over 2 meters (m) above the roof.

(4) When there is a partition valve at the entrance of the relief valve, the partition valve should be in a normal open state and be sealed with lead to avoid mistakes.

(1) The cross-sectional area of the connecting pipe and the through-hole of the pipe fittings between the safety valve and the boiler or pressure vessel shall not be less than the import cross-sectional area of the safety valve; if several safety valves share an import pipe, the flow cross-sectional area of the import pipe shall not be less than the sum of the import cross-sectional area of the safety valve.

(2) No cut-off valve or steam outlet pipe shall be installed between the safety valve and the drum or header of the boiler. It is not suitable to install cut-off valves or other lead-out pipes between safety valves and pressure vessels. For pressure vessels with extremely high, high and moderate toxicity, inflammable, corrosive, viscous or precious media, the cut-off can be installed between safety valves and pressure vessels only with the approval of the technical person in charge of the pressure vessel of the user unit and the formulation of reliable preventive measures. Valves. During normal operation of pressure vessel, globe valve must be kept fully open, sealed or locked with lead. The structure and diameter of the stop valve shall not hinder the safe discharge of the safety valve.

(3) Spring safety valve with thread connection should be connected with short pipe with thread, and welding connection should be used between short pipe and simplified body and header.

(4) Safety valves must be equipped with discharge pipes. The discharge pipe should avoid twists and turns as far as possible to minimize resistance. The exhaust pipe should go straight to the safe place and have enough cross-section area to ensure smooth exhaust. For safety valves that can interact to produce chemical reactions, one discharge pipe cannot be shared; when safety valves are installed on equipment with corrosive and flammable gases, measures should be taken to prevent corrosion or fire and explosion; when the equipment equipped with safety valves is toxic medium and the steam density of the medium is greater than air density, the medium and steam discharged from safety valves should be introduced. To the closed system, and from the closed system recovery to production use.

(6) Safety valves installed in the open air shall be equipped with reliable measures to prevent the water content in the medium of the valve from freezing and affecting the discharge of the safety valve when the temperature is below 0 oC.

(7) When the medium crystallization temperature of the safety valve is higher than the lowest ambient temperature, the safety valve must be equipped with an insulating jacket and installed with insulating and purging steam to prevent the medium crystallization from clogging the safety valve and affect the normal operation performance of the safety valve. The inlet and outlet pipes of safety valves must also be designed with steam insulation jackets or with additional insulation steam accompanying pipes to prevent medium crystallization from clogging the pipes.

1. Safety valve should have a device to prevent the weight from moving by itself and a guide to limit the deviation of lever. Spring safety valve should have a lifting handle and a device to prevent the screw from screwing randomly.

2. It should be installed vertically at the highest position of the cooker and header. Between the safety valve and the drum or header, there shall be no outlet pipe and valve for taking steam.

3. The cross-sectional area of the connecting pipe between the safety valve and the boiler shall be no less than the cross-sectional area of the inlet of the safety valve. If several safety valves are installed on a short tube directly connected to the pot drum, the cross-section area of the short tube should not be less than 1.25 times the exhaust area of all safety valves.

4. For boilers with rated steam pressure less than or equal to 3.82 MPa, the throat diameter of safety valve shall not be less than 25 mm; for boilers with rated steam pressure greater than 3.82 MPa, the throat diameter of safety valve shall not be less than 20 mm.

5. Safety valves should generally be equipped with exhaust pipes, which should go straight to the safe place and have enough cross-section area to ensure smooth exhaust. The bottom of the relief valve exhaust pipe should be equipped with a drain pipe connected to the safe place. Valves are not allowed to be installed on the exhaust pipe and the drain pipe.

6. The safety valve of pressure vessel should be installed directly at the highest position of pressure vessel body. Safety valves for liquefied gas tanks must be installed in the gas phase. Generally, the short pipe can be connected with the container, and the diameter of the short pipe of the safety valve should be no less than the diameter of the safety valve.

7. Valves should not be installed between safety valves and containers. For flammable, explosive or viscous media containers, globe valves can be installed in order to facilitate the cleaning or replacement of safety valves. The globe valves must be fully opened and sealed with lead during normal operation to avoid chaos.

8. Boilers with rated evaporation greater than 0.5 t/h shall be equipped with at least two safety valves; boilers with rated evaporation less than or equal to 0.5 t/h shall be equipped with at least one safety valve. Safety valves must be installed at the outlet of separable economizer and steam superheater.

9. For pressure vessels with flammable, explosive or toxic media, the medium discharged by the safety valve must have safety devices and recovery systems. The installation of lever relief valve must keep the vertical position, and spring relief valve should also be installed vertically to avoid affecting its action. When installing, attention should also be paid to coordination, coaxiality of parts and uniform stress of bolts.

Boilers are in homes; industries and properties across the country, and these important pieces of equipment have safety devices installed in them to make sure that residents and their families can enjoy the practical benefits of hot water on demand without placing themselves at risk. One of these devices is a boiler safety valve.

Boilers operate under a lot of pressure, and the hot water and steam they contain can cause severe injury if the boiler should fail. Safety valves work to protect lives from a variety of boiler failures, including:

The valve works to relieve the pressure building up inside the boiler. Without this pressure relief, the boiler is at risk of bursting. All boilers are required to have at least one of these valves, depending on the boiler’s capacity. In the USA, only non-assisted safety valves are permitted, and they are located inside the boiler steam drum itself. If the pressure rises above the recommended level for safety, these are automatically open and release excess pressure to take the strain off the boiler drum.

Once pressure is back down to safe levels, the valve will reset itself to prevent the pressure dropping too far and wasting energy. This reset mechanism reactivates the safety valve, which will then trigger again if the pressure gets too high.

Relief and safety Valves are used in high pressure systems to control the pressure and keep balance of the system. The different between safety valves and relief valves is that the safety valves fully open or close under a certain pressure while the relief valves can open in proportion to the pressure in front of them. The safety and pressure relief valves are used automatically. They both operate under similar conditions. When the pressure builds up in a system, it has to be managed by releasing the material to flow through. These valves have a threshold pressure at which they open. The consolidated safety and safety relief valves comprise of a bonnet vent and bellow with springs.

The springs are set up for the threshold pressure and when the pressure exceeds the threshold, the spring is pushed into the bonnet vent and the bellow opens the valve. The Safety Relief Valves can be open and shut valves. They either open or shut off at any given pressure. This is mostly for the safety of an application not to explode under high pressure. The Pressure Relief Valve on the other hand releases the material after the threshold pressure, but not fully. If the pressure is slightly higher the threshold, then the valve opens slightly. If the pressure is very high above the threshold, it opens wider. It also functions in the same manner when the pressure drops down. The valve closes in proportion to the pressure. The safety valve shuts down at once only when the pressure is below the threshold.
