Abstract
The invention discloses a kind of valve seal piston component, including valve body, piston；Piston is set to valve inner, and piston is fitted close with valve body；First sealing ring and the second sealing ring on piston outer periphery are set, O-ring is placed in the first sealing ring, the second sealing ring, is bonded on the outside of O-ring with valve interior wall extruding；The both ends of piston are respectively water inlet end and water outlet.In the present invention, flow is entered by water inlet end in piston, and flows out piston by water outlet；In traditional valve, piston outer periphery only sets a sealing ring, its poor sealing, the phenomenon that will appear flow infiltration, and the present embodiment is respectively arranged with the first sealing ring, the second sealing ring in piston outer periphery, first sealing ring, the second sealing ring have buffering, blocking effect to water impact, infiltration, and the setting of two sealing rings so that its air-tightness is better, and flow will not be passed through by the gap between valve body, piston.
Description
Technical field
The present invention relates to valve field more particularly to a kind of valve seal piston components.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief.For the valve of fluid control systems, from simplest shut-off valve to extremely complex robot control system(RCS)
Used in various valves, kind and specification are quite various, and in the production process of valve, the leakproofness of valve is and its again
It wants.
In traditional valve mechanism, leakproofness and imperfect between the piston and valve body of valve inner, the present embodiment is to work
Plug structure is transformed, and further strengthens the leakproofness between piston and valve body.
Invention content
To solve technical problem present in background technology, the present invention proposes a kind of valve seal piston component, and enhancing is lived
Leakproofness between plug and valve body.
A kind of valve seal piston component proposed by the present invention, including valve body, piston；Piston is set to valve inner, living
Plug is fitted close with valve body；First sealing ring and the second sealing ring, the first sealing ring, the second sealing ring are set on piston outer periphery
Interior placement O-ring, O-ring outside are bonded with valve interior wall extruding；The both ends of piston are respectively water inlet end and water outlet.
Preferably, the width of the first sealing ring and the second sealing ring is 1-2 millimeters.
Preferably, a diameter of 2 millimeters of O-ring.
Preferably, 1-2 millimeters are spaced between the first sealing ring, the second sealing ring.
In the present invention, at work, flow is entered by water inlet end in piston the valve seal piston component proposed, and by
Flow out piston in water outlet；In traditional valve, piston outer periphery only sets a sealing ring, poor sealing, it may appear that flow is oozed
The phenomenon that saturating, and the present embodiment is respectively arranged with the first sealing ring, the second sealing ring, the first sealing ring, second in piston outer periphery
Sealing ring has buffering, blocking effect to water impact, infiltration, and the setting of two sealing rings so that its air-tightness is better, water
Stream will not be passed through by the gap between valve body, piston
Description of the drawings
Fig. 1 is the structure diagram of valve seal piston component proposed by the present invention.
Specific embodiment
As shown in FIG. 1, FIG. 1 is a kind of structure diagrams of valve seal piston component proposed by the present invention.
With reference to Fig. 1, a kind of valve seal piston component proposed by the present invention, including valve body 1 and piston 2；Piston 2 is set to
Inside valve body 1, piston 2 is fitted close with valve body 1；First sealing ring 5 and the second sealing ring 6 be set on 2 periphery of piston, first
O-ring is placed in sealing ring 5, the second sealing ring 6, is bonded on the outside of O-ring with the extruding of 1 inner wall of valve body；The both ends of piston 2 are respectively
Water inlet end 3 and water outlet 4.
In the specific work process of the valve seal piston component of the present embodiment, flow is entered by water inlet end 3 in piston, and
Piston is flowed out by water outlet 4；In traditional valve, piston outer periphery only sets a sealing ring, poor sealing, it may appear that flow
The phenomenon that infiltration, and the present embodiment is respectively arranged with the first sealing ring 5, the second sealing ring 6, the first sealing ring in 2 periphery of piston
5th, the second sealing ring 6 has buffering, blocking effect to water impact, infiltration, and the setting of two sealing rings causes its air-tightness more
Add, flow will not be passed through by the gap between valve body 1, piston 2；
In a specific embodiment, the width of the first sealing ring 5 and the second sealing ring 6 is 1-2 millimeters；
Further, a diameter of 2 millimeters of O-ring.
Further, 1-2 millimeters are spaced between the first sealing ring 5, the second sealing ring 6.
Above structure setting has good effect to leakproofness, further ensure that between piston 2, valve body 1
Leakproofness so that better tightness.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
