Installation method of rising stem gate valve

When assembling the rising stem gate valve, in order to prevent metal, sand and other dirt from invading the gate valve and damaging the sealing surface; a filter and a flushing valve must be set. In order to keep the compressed gas clean, an oil-water separator or an air filter should be assembled before the gate valve. Fully considering the working environment of the gate valve during operation, it is necessary to set the instrument and check valve.
The gate valve manufacturer said that in order to maintain the working temperature, heat preservation facilities should be set outside the gate valve; for the installation behind the valve, a safety valve or check valve must be set; fully considering the continuous operation of the gate valve, which is convenient and dangerous, set up a parallel system or a bypass system.
1. Check the gate valve maintenance facilities:
In order to avoid adverse effects such as product quality degradation and accidents caused by leakage or medium backflow after the check valve fails, one or more shut-off valves are installed around the check valve. If given 2 shut-off valves, the check valve can be easily disassembled and repaired.
2. The implementation of the maintenance of the rising stem gate valve safety valve
The shut-off valve is basically not installed before and after the installation method, and must be used in individual cases. Friendly reminder, if the medium force contains solid particles, it will affect the inability of the safety valve to lock after takeoff. Therefore, a lead-sealed gate valve should be installed around the safety valve. The gate valve and safety valve should be fully opened, and a DN20 check valve leading to the atmosphere should be installed directly. Gate valve manufacturers
3. Maintenance facilities of the pressure reducing valve:
There are generally three main types of pressure relief valve installation facilities. There are pressure gauges on the front, rear, left, and right sides of the pressure reducing valve, which is beneficial to observe the pressure before and after the valve. Install a fully enclosed safety valve behind the gate valve to prevent the gate valve from malfunctioning. When the pressure after the valve exceeds the normal pressure, the system after the valve will jump. Gate valve manufacturers
The drain pipe is installed in front of the stop valve in front of the gate valve and is mainly used for flushing the drainage channel. Some of them use steam traps. The bypass pipe is mainly used to close the shut-off valve, open the bypass valve, and manually adjust the flow before and after the pressure reducing valve fails. It can be cycled, then repaired and replaced with a new pressure reducing valve.
4. Maintenance facilities for steam traps:
The rising stem gate valve manufacturer said that there are two types of traps with bypass pipes and without bypass pipes, which involve steam traps with special requirements such as condensate recovery, condensate non-recovery, and drain payment. Capable of parallel assembly. Our own engineers kindly reminded that when servicing the trap, it is not necessary to drain the condensate through the bypass line, this will allow the steam to escape and return to the water system. Under normal circumstances, there is no need to assemble a bypass pipe, and it is only for heating equipment that requires strict heating temperature in continuous production.
