Abstract
The utility model discloses a piston type multi-function control valve which comprises a valve body and a valve stem connected with the valve body. A piston guide cavity is arranged in the valve body, the valve stem is connected with a rocker, the rocker is arranged in the piston guide cavity, the rocker is articulated with a connecting rod, the other end of the connecting rod is connected with the piston, the piston has a seal contact with a valve seat arranged on the valve body. The position of the control valve gate has a linear relationship with the opening, the piston stay at different position to realize different opening, and can be used as basic main valve body of various control function valves to combine with the control function valve. The control function valve comprises a control valve, a pressure reducing valve, a check valve, a flow control valve and a relief valve. The control valve has a self cleaning characteristic, when opened, loop injection is formed around the piston to flush the sealing surface; the opening force is low, and water pressure equilibration is provided, thus the opening operation is not affected by the pressure in the pipeline.
Description
Technical field
The utility model belongs to control valve, is specifically related to be between a kind of valve location and the aperture piston control valve of linear relationship.
Technical background
The various control valves of using in pipeline at present can not bear big pressure, High Pressure Difference as the basic valve body of fluid level control valve, reduction valve, safety check, flow control valve and Decompression valves etc., can not accomplish heavy caliber, anti-silt ability; In addition, the control valve that existing aperture is adjustable is difficult to reach linear relationship between the position of its valve and the aperture.
Summary of the invention
The purpose of this utility model is to provide a kind of piston type multifunctional control valve that can use as the basic main valve body of above-mentioned control valve, the problem when using to solve above-mentioned control valve.
The technical solution of the utility model is: the piston type multifunctional control valve comprises valve body, the valve rod that is connected with valve body, be provided with the piston guide chamber in the valve body, valve rod connects rocking bar, rocking bar is located in the piston guide chamber, rocking bar and rod hinge connection, the other end of connecting rod connects piston, and piston contacts with valve base sealing on being located at valve body.
It between the position of the valve of this control valve and the aperture linear relationship, piston rests on different positions and realizes different open degree, the basic main valve body that can be used as various control function valves uses, and comprises fluid level control valve, reduction valve, safety check, flow control valve and Decompression valves etc.It is the tool self-cleaning also, and during unlatching, the piston periphery forms ring spray and penetrates flushable sealing surface; Its opening force is little, and it has the hydraulic balance effect, is not subjected to the pressure influence in the pipeline during unlatching.
