Abstract
The utility model relates to a hydraulic piston valve which is composed of a valve body, a valve seat, a valve cover, a valve plug, a valve rod, a piston, etc., wherein, the valve seat and the valve cover are in strew connection with the valve body; a water inlet hole and a water outlet hole on the valve seat are rectangular-shaped. Opening and closing of the valve plug are realized by utilizing the flow pressure difference to enable straight reciprocating motion of the piston, the valve plug, etc. The utility model has the advantages of reasonable structure, reliable motion, good tightness, long service life and high durability, and can be utilized in equipment which uses flow pressure difference to realize automatic control.
Description
The utility model relates to a kind of valve, the fluid-operated piston valve that particularly utilizes fluid pressure difference to control automatically.
At present, the petcock of the balance pressure reduction that some equipment disposed utilizes the rubber matrix in valve pocket, seal and transmit hydrodynamic pressure.Sealing and unlatching valve plug are to reach the purpose of pressure release.Because the rubber matrix is soft and thin, diaphragm is worn in working in reciprocating mode, makes the valve cisco unity malfunction, influences the operation of corollary equipment.
The purpose of this utility model provides a kind of reliable in action, long-lived fluid-operated piston valve.
The technical solution of the utility model is achieved in that
The utility model is made up of valve body, valve seat, valve gap, valve plug, valve rod, piston etc.Left upper end shoulder at valve body is provided with liquid flow hole, and the valve gap utilization is threaded in the valve body right-hand member, also is provided with liquid flow hole in the valve gap center.The valve seat utilization is threaded in the left end of valve body, is provided with water inlet and osculum at valve seat, water inlet and the osculum shape that meets at right angles.Valve rod is installed valve plug, valve plug holder, with pressing plate and nut valve plug is fixed on valve plug holder left side at the left end of valve rod by the center hole of valve body.Right-hand member at valve rod has two clamping plate clampings rubber piston, by guide pin bushing, packing ring, nut piston is fixed.One end of spring withstands in the guide pin bushing groove, and the other end withstands in the left side groove of valve gap.
Accompanying drawing 2 is the utility model opening state structure sectional views.
In conjunction with the accompanying drawings the utility model embodiment is described in further detail:
Valve seat (1) is connected on the valve body (8), and valve gap (9) also is connected on the valve body (8).Valve rod (18) left end compresses locking with pressing plate (2) and nut with valve plug (3) by dress valve plug (3), valve plug holder (4).The right-hand member of valve rod (18) is installed the rubber piston (16) by two clamping plate (7), (15) clamping.Guide pin bushing (14) compresses locking with packing ring (12) nut (13) with piston (16).One end of spring (10) withstands in guide pin bushing (14) outer side slot, and the other end of spring (10) withstands in the inner side slot of valve gap (9).Valve stem casing (5) and seal ring (17) are contained in the left side center hole of valve body (8), and valve rod (18) can straight reciprocating motion in the valve stem casing (5) in valve body (8).

2+ spring force), hydrodynamic pressure enters valve body (8) chamber inner carrier (16) left side from valve body (8) liquid flow hole (6).Hydrodynamic pressure promotes piston (16) and moves right, and is pushed into the right-hand member in valve body (8) chamber.Former valve body (8) chamber inner carrier (16) right side fluid releases from the liquid flow hole (11) of valve gap (9).Valve rod (18) drives valve plug (3) and moves right, and osculum (20) is opened, and fluid enters valve seat (1) chamber from the water inlet (19) of valve seat (1), releases from osculum (20) discharging.P
1=P
2The time, under spring (10) effect, valve rod (18) piston (16) valve plug (3) is set back, valve plug (3) stops up osculum (20).
The utility model compared with prior art has the following advantages:
The utility model utilizes metallic plate clamping rubber piston to do transmission and movement parts, than tradition The rubber matrix durable, good airproof performance has guaranteed the proper motion of valve to make the corollary equipment energy Enough reliable normal operations. This valve can be widely used in relying on the fluid pressure difference realization automatically to control In the various device.
Claims (1)
1. one kind by fluid-operated piston valves that part constituted such as valve body, valve seat, valve gap, valve plug, valve rod, pistons, and it is characterized in that: the rubber piston by two clamping plate clampings is housed on the valve rod of body cavity.
