RVP Plate Type Check Valve
RVP plate check valve is a one-way flow control device widely used in hydraulic systems. The following is a detailed introduction:
1. Basic structure and working principle
Structural composition
RVP plate check valve is mainly composed of valve body, conical valve core, spring and spring seat. The valve body is made of steel, with a compact structure and a small installation size, making it easy to integrate the design. The conical valve core cooperates with the spring seat to automatically open and close the valve port.
How it works
Forward flow: When oil flows in from the inlet, the pressure overcomes the spring force to push the cone valve core to open, and the oil flows smoothly through the valve port to the outlet.
Reverse cutoff: When the oil attempts to flow in reverse, the cone valve core closes the valve port under the combined action of spring force and oil pressure to prevent the oil from flowing back.
2. Technical parameters and performance characteristics
Diameter range
RVP plate check valves are available in a variety of diameter specifications, including 6, 8, 10, 12, 16, 20, 25, 30, 40, etc., to meet different flow requirements.
Turn on the pressure
The opening pressure of the check valve is 0.05 MPa, ensuring reliable operation at low pressures.
Pressure loss
The tapered valve structure is adopted, and the pressure loss is small, which helps improve system efficiency.
Temperature and media adaptability
Suitable for temperature ranges from -30°C to +80°C, the medium can be mineral hydraulic oil or phosphate hydraulic oil, with a viscosity range of 2.8 to 500 mm²/s.
3. Functions and applications
Main function prevents oil from flowing in reverse and protects hydraulic system components.
It is used as a backpressure valve at the outlet of the pump to maintain the system pressure stability.
It can be combined with throttle valves, sequential valves, etc. to form a one-way throttle valve or one-way sequential valve to expand the system functions.
Application areas
RVP plate check valves are widely used in industrial automation systems, hydraulic transmission devices, engineering machinery, agricultural machinery and other fields, especially in situations where precise control of the one-way flow of fluid is required.
4. Precautions for installation and use
Installation direction
During installation, you must know the direction of the inlet and outlet ports to ensure that the valve body arrow points in the same direction as the oil flow, and avoid system failure caused by reverse installation.
Working pressure and flow
During normal operation, the working pressure should be lower than the rated value, and the flow rate should be within the allowable range of the diameter to avoid excessive pressure loss.
Turn on pressure selection
Select the appropriate opening pressure according to the system functional requirements. The opening pressure is usually higher when used as a back pressure valve and is determined by the back pressure value.
Installation location
Avoid installing the check valve directly at the outlet of hydraulic pumps with weak self-priming capabilities, especially high-pressure vane pumps, plunger pumps, etc., and take exhaust measures if necessary to prevent air suction failure.
V. Model and specifications
RVP plate check valves are available in a variety of models, such as RVP-6, RVP-8, RVP-10 to RVP-40, etc. Each model corresponds to different diameters and flow specifications. Users can choose the appropriate model according to actual needs.
