Safety valve

Product overview

The safety valve is an indispensable pneumatic component in the clutch work. The function is to ensure that the pressure of the clutch can not be super high, which is beneficial to the normal working of the clutch.

 

Product effect

Safety valve in the system play a safety role. When the system pressure exceeds the specified value, the safety valve is opened to vent some of the gas / fluid in the system to the atmosphere / piping so that thesystem pressure does not exceed the allowable value to ensure that thesystem will not cause an accident due to excessive pressure.


Safety valve selection principle

1.Steam boiler safety valve, the general use of open all-spring-type safety valve 0490 series;

2. Liquid medium with safety valve, the general selection of micro-spring-type safety valve 0485 series;

3. Air or other gas medium with safety valve, the general use of all-spring-type safety valve;

4.Liquefied petroleum gas tanker truck or liquefied petroleum gas tanker truck safety valve, the general use of Kai-type built-in safety valve;

5. Oil well export safety valve, the general choice of pilot-operated safety valve;

6.Steam power generation equipment, high pressure bypass safety valve, the general use of safety and control of dual function pilot safety valve

7.If the safety valve is required to regularly open the test, the safety valve with lifting wrench should be used. When the medium pressure reaches more than 75% of the cracking pressure, the lift wrench can lift the valve flap slightly from the valve seat to check the opening of the safetyvalve.

8.If the medium temperature is high, in order to reduce the temperature of the spring chamber, generally when the closed safety valve temperature exceeds 300 ℃ and open safety valve temperature exceeds 350 ℃,should be used with a safety valve with a radiator;

9. If the safety valve outlet back pressure is variable, the change of more than 10% of the opening pressure, the bellows safety valve should be selected;

10.If the medium is corrosive, bellows safety valve should be used to prevent important parts due to media corrosion failure.

11. Safety valve installation and maintenance should pay attention to the following points Construction, installation points 1), installation location, height, direction of import and export must meet the design requirements, pay attention to the flow direction of the media should be consistent with the direction of the arrow marked body, the connection should be solid close. 2), the appearance of the valve must be installed before the inspection, the valve nameplate should be consistent with the current national standard "General Valve Flags" GB 12220 requirements. For the working pressure is greater than 1.0 MPa and the main pipe to play the role of cut-off valve, the installation should be carried out before the intensity and tightness test, qualified after the standard use. Strength test, the test pressure of 1.5 times the nominal pressure, the duration of not less than 5min, valve housing, packing should be no leakage as qualified. Tightness test, the test pressure is 1.1 times the nominal pressure; test duration of time in line with the requirements of GB 50243. 1. All kinds of safety valves should be mounted vertically.

12. Safety valve outlet should be no resistance, to avoid compression phenomenon.

13. Safety valve should be specially tested before installation, and check the sealing.

14. The use of safety valves should be regularly checked
