overflow valve

Relief valves in the form of the structure and type of moving into straight-pilot, and it's up in Hydraulic Pump export guarantee system, or limitation of the maximum pressure constant pressure, sometimes adjacent to import components in the implementation of the components of its security role. Straight moving type relief valves, mainly valve disc, valve body,, spring-loaded, roof, regulation pole, conditioning nut, and other integral parts.



Pilot valves and pilot-type relief valves are the main valves of two parts, pilot valves for cone valve, the flow is a small direct action type relief valves. With import pressure relief valves, pilot vavel disc role in the fluid pressure Fx attendant increase, when more than equal to Fx Pt2, pilot valves valves mouth opened, the pressure relief valves to import oil by damping hole, Pilot valves valves mouth overflow relief valves to export, and then back to the fuel tank. Imported oil pressure relief valves to the main valve valves mouth overflow back containers. Main valves valves mouth open for some time, pilot valves and the valve Faxin Faxin respectively in the balance of power, pressure flow valves meet the equation mouth, and the main valve to the pressure of a determined value of imports.

Valve role

Valve is a widely used mechanical product in each country's economy. You can find valves commonly used in the following fields like oil, nature gas, coal, metallurgy, mining, refinery, pipe transportation, petrochemical, chemical, pharmacy, food production, power plant, water supply / drainage, heat supply, air supply, marine, vehicle, airplane, spacecraft, military, new tech, irrigation and many other flowing systems.

There are self-driven valves and operated valves. self-driven valves( like safety valve, relief valve, steam trap, check valve ) are functioning by utilizing its mechanical design or the pressure, direction of its flow medium.operated valve( like gate valve, globe valve, ball valve, butterfly valve ) is fuctioning by actuator( manual, electric, hydraulic, pneumatic etc. ) or the pressure , flow direction of its medium. due to the differences of pressure, temperature, flow, and physical-chemical character of its medium , there are different requirements in designing and applying the pipeline system.therefore there are numerous types of valve.according to an unofficial statistics, there are more than four thousand types of valve with approximately forty thousand specifications in China. Obviously, valve is an important element in the social economy.

Check Valve


The series of products for the industrial cycle for drainage, wastewater treatment plant and high floor building, and the Hotels High Pressure output pumps, automatic elimination of destructive water hammer, thereby ensure pumps and pipes are not damaged. Designed to take full consideration use of environmental requirements, has conducted several technical transformation. The new product mix, small size, small fluid resistance, a smooth operation, reliable sealing, resistance to erosion and abrasion-resistance, Buffer capability is good and so on.

This product can use to water industrial, sanitary ware, pharmaceutical industry, and refrigeration industry.
