Installation of common valves

Gate Valve installation
Gate valve, also known as gate valve, is a kind of gate plate control pipeline opening and closing, by changing the cross section to adjust the pipeline flow and pipeline opening and closing valve. Gate valves are used for fully open or fully closed pipeline operation in fluid medium. Gate valve installation generally has no directional requirements, but can not be inverted.
Installation of stop valve
Globe Valve is a valve that uses a disc to control the opening and closing of the valve. By changing the clearance between the disc and the seat, that is, changing the size of the channel section, adjust the medium flow or cut off the medium path. Pay attention to the flow direction when installing the globe valve.
When installing the globe valve, the principle must be followed is that the fluid in the pipeline from the valve hole from the bottom up, commonly known as "low into high", reverse installation is not allowed.
Installation of check valves
Check valves, also known as check valves and check valves, are valves that automatically open and close according to the pressure difference between the front and back of the valve. Its function is to make the medium flow in only one direction and prevent the media from reverse reflux. According to the different structure of the Check Valve, it can be divided into lift, swing and butterfly. Lift check valves can be divided into horizontal and vertical. When installing check valves, pay attention to the medium flow direction.
Pressure reducing valve installation
A pressure reducing valve is a valve that reduces the inlet pressure to the desired outlet pressure by adjusting it and automatically keeps the outlet pressure stable according to the energy of the medium itself.
From the perspective of fluid mechanics, pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow and kinetic energy of the fluid can be changed, so as to produce different pressure losses, so as to achieve the purpose of reducing pressure. Then, according to the adjustment of the control and regulation system, the fluctuation of the pressure after the valve is balanced with the spring force, so that the pressure after the valve is kept constant within a certain error range.
Installation of drainage valve
The basic function of the trap is to discharge condensate, air and carbon dioxide in the steam system as soon as possible; At the same time can automatically prevent the maximum steam leakage. There are many kinds of traps with different performance.
Installation of safety valve
Safety valve is a special valve whose opening and closing parts are closed normally under the action of external forces. When the medium pressure in equipment or piping rises above the specified value, the medium pressure in the piping or piping is prevented from exceeding the specified value by discharging the medium outside the system.
Safety valve is a kind of automatic valve, mainly used in boilers, pressure vessels and pipelines. Control pressure does not exceed the specified value, to protect personal safety and equipment operation plays an important role. Safety valve must be tested before use.
