Precautions for using the back pressure valve! (Fluid connectors)

Thread Content

In the outlet pipeline, a backpressure valve should be used in conjunction with a pulsation damper, the latter being used to absorb the flow rate peaks between the pump and the backpressure valve. In the absence of a pulsation damper, the backpressure valve will open and close rapidly with each pump stroke. With a pulsation damper, the back pressure valve will oscillate between half-open and half-closed positions; thus, the pulsation damper can reduce the wear rate of the back pressure valve. For pumps with high flow rates and long, thin outlet pipes, the backpressure valve should be installed near the filling point in order to reduce the tendency for siphoning. When transporting a medium containing suspended solids, a tee (or cross) with a pipe plug should be installed at the inlet of the backpressure valve, allowing the pipeline to be cleaned without disassembly. A backpressure valve is merely a piping component; it can achieve its maximum effectiveness only when used in combination with other piping components such as pulsation dampers, safety valves, check valves, globe valves, and filters. Precautions for using backpressure valves – A manufacturer of high-pressure metal hoses explains them to you: First point: During installation, it is necessary to avoid resonance with the system; otherwise, it will have a serious impact on the operation of the backpressure valve and may even cause damage to it, posing a risk. Second point: When used in conjunction with a pulsation damper, the latter should be installed between the pump and the back pressure valve in order to absorb the flow rate peaks between them. Reduce the wear rate of the back pressure valve. Third point: A protective canopy or cover should be used for outdoor use. Fourth point: Before performing any maintenance on the backpressure valve, the equipment must be stopped, the pressure released, the valve connecting the backpressure valve to the system closed, and it must be confirmed that there is no pressure in the pulsation damper. Be careful to avoid being injured by the liquid being transported during maintenance. Fifth point: The backpressure valve is directional. If the inlet and outlet of the backpressure valve are reversed, the backpressure will increase exponentially, posing a threat to the system and potentially leading to danger. Sixth point: If a fault is detected in the back pressure valve during operation, the system should be stopped immediately, or the pipeline containing the back pressure valve should be shut off to cease its use, after which the back pressure valve should be inspected and replaced. Point 7: Before performing any inspections or maintenance on the backpressure valve, the equipment must be shut down, the pressure within the valve released, the valves connecting the backpressure valve to the system closed, and it must also be confirmed that there is no pressure in the pulsation damper. Be careful during maintenance to prevent high-pressure fluid inside the valve from splashing and causing injury to people. Point eight: The pipe diameters available are eleven models: DN6, 8, 10, 15, 20, 25, 40, 50, 65, 80, and 100. The inlet pressure is available in two series of 0.3 MPa and 1.0 MPa, and the pressure difference between the inlet and outlet can be adjusted by changing the length of the spring. For import and export connections, three options are available: internal threads, flanges, and hose fittings. Our company’s products:
