Abstract
A regulation type equalizing piston valve relates to a valve, in particular to a regulation type equalizing piston valve. A stable regulating spring (9) is sleeved to a valve rod (4) in a valve body (1). The upper end of the stable regulating spring (9) is propped against a valve body cover (1-1), while the lower end thereof is propped against a piston (3). A sealing sleeve (6) is fixedly connected into the valve hole of a valve seat (2). The piston (3) is arranged in the sealing sleeve (6). A sealing gasket (7) is further mounted on the upper surface of the piston (3). A rubber layer (8) is adhesively fixed to the inner space surface of the valve body (1). The utility model is characterized in that: the piston is capable of compressing the spring when the liquid pressure in a pipe is high, so that the valve is automatically opened; and the stable regulating spring having a different elastic force is mounted, the opening degree of the valve can be determined. Moreover, the utility model solves the problems of leakage and short service life of the existing piston valve.
Description
Technical field
The utility model relates to valve, particularly a kind of adjustment type equalizing piston valve.
Background technique
The existing piston valve leakage phenomenon can occur when conveying contains impurity and corrosive liquids, and valve inner can be corroded very soon, thereby shortens the working life of valve body.
The model utility content
The purpose of this utility model provides a kind of adjustment type equalizing piston valve, and the utility model has solved existing piston valve leakage phenomenon can occur, and the problem of lacking working life.
Adjustment type equalizing piston valve of the present utility model has valve seat 2 in valve body 1, piston 3 is connected valve rod 4 lower ends, and piston 3 cooperates with the valve opening of valve seat 2; In valve rod 4 and body cap 1-1 cooperation place Packing seat 5 is installed; Be set with steady Regulation spring 9 on the valve rod 4 in valve body 1, steadily the upper end of Regulation spring 9 withstands on the body cap 1-1, and steadily the lower end of Regulation spring 9 withstands on the piston 3; Valve opening internal fixation at valve seat 2 is connected with stuffing box gland 6, and piston 3 is arranged in the stuffing box gland 6, and seal washer 7 also is installed on piston 3; Valve body 1 surface of internal cavity also cementation rubber layer 8 is arranged.
The utility model is when the pipeline fluid pressure is big, and piston can open valve length of spring compressed automatically, by the steady Regulation spring of different elasticity dynamics is installed, promptly can determine the unlatching dynamics of valve; Stuffing box gland is installed on valve seat, seal washer is installed on the piston, guaranteed the sealing of piston valve.Cementation has rubber layer on the body cavity surface, has prevented the corrosion of corrosion liquid to valve body, thereby has prolonged the working life of piston valve.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: valve body 1, body cap 1-1, valve seat 2, piston 3, valve rod 4, Packing seat 5, stuffing box gland 6, seal washer 7, rubber layer 8, steady Regulation spring 9.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1, adjustment type equalizing piston valve has valve seat 2 in valve body 1, and piston 3 is connected valve rod 4 lower ends, and piston 3 cooperates with the valve opening of valve seat 2; In valve rod 4 and body cap 1-1 cooperation place Packing seat 5 is installed; Be set with steady Regulation spring 9 on the valve rod 4 in valve body 1, steadily the upper end of Regulation spring 9 withstands on the body cap 1-1, and steadily the lower end of Regulation spring 9 withstands on the piston 3; Valve opening internal fixation at valve seat 2 is connected with stuffing box gland 6, and piston 3 is arranged in the stuffing box gland 6, and seal washer 7 also is installed on piston 3; Valve body 1 surface of internal cavity also cementation rubber layer 8 is arranged.
Have bypass valve on the valve body, the bidirectional balanced pressure difference of can regulate, other outer hand wheel upper end is provided with the dial loam cake, and along with valve opening, valve rod rises the moving size of deciding total discharge of how much measuring.
Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
