Abstract
The utility model discloses a valve sealing component which belongs to the field of sealing assembly components; the structure comprises a valve clack and a positioning core; one surface of the valve clack is an arc surface and the other surface is a plane surface; a circular groove matching with an O-shaped ring is opened on the arc surface of the valve clack; the plane surface of the valve clack is provided with a connecting rod; the connecting rod and a connecting rod hole on the positioning core are slidingly connected; a spring is covered on the connecting rod; one end of the spring is connected with the positioning core, and the other end is connected with the plane surface of the valve clack. Compared with the prior art, the valve sealing component of the utility model is characterized by reasonable design, simple structure, convenience in installation and repairing, good sealing effect, low processing cost, etc.
Description
Technical field
The utility model relates to a kind of black box, specifically a kind of valve body sealing component.
Background technique
At present the clapper of one-way valve and valve body is sealed with two kinds of sealing means, a kind of is that flap is a plastic cement material, combines dependence itself and valve seal with spring, and another is the metal flap, combine with the seal ring that embeds valve body, utilize the pressure of waterpower to seal.There is the defective aging, non-refractory that goes bad in the material of the former flap; Latter's seal ring is fixed owing to be embedded on the valve body, and the axle center of flap is often departed from the axle center of seal ring and caused leakage in the actual motion state, can't play single effect, and it necessarily requires fluid that certain pressure is arranged, could be with extruding mutually between flap and the seal ring.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and a kind of good sealing effect is provided, a kind of valve body sealing component that processing cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: the sealing member comprises flap and location core, the one side of flap is a cambered surface, another side is the plane, have the circular groove that matches with O shape circle on the cambered surface of flap, the plane of flap is provided with connecting rod, and connecting rod slides with the tie rod holes on the core of location and links to each other, and connecting rod sleeve has spring, one end of spring links to each other with the location core, and the other end links to each other with the plane of flap.
Described flap and location core are installed in the body cavity, and the cambered surface of flap cooperates with through hole on the valve body, and the O shape on the flap cambered surface is enclosed and contacted with valve interior wall under the pressure of external force and spring.
The utility model combines the advantage of the sealing means of present two kinds of clappers and valve body, and O shape circle is installed on the flap, cut out a circular groove on the cambered surface of flap, the mode that adopts seal ring to embed allows O shape circle be offset with the skew of flap, avoids consequent leakage problem.Utilize the pressure of spring simultaneously, the O type circle between flap and the valve body is squeezed, thereby play the effect of sealing, and the effect of dependence waterpower that needn't be single.
When fluid from flap one lateral register core one side flow, hydrodynamic pressure during greater than spring force, fluid be able to by, when fluid during from location core one side direction flap one side flow, fluid is cut off, and plays the effect of safety check.
The mode that employing is slotted on the flap cambered surface greatly reduces difficulty of processing and cost, has improved machining accuracy, reduces the defective products rate.The assembling difficulty of O type circle and flap is reduced, improved the efficient of producing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the structural representation of valve body sealing component.
Accompanying drawing 2 is the structural representation that valve body sealing component combines with valve body.
Among the figure: 1, O shape circle, 2, flap, 3, spring, 4, the location core, 5, tie rod holes, 6, connecting rod, 7, circular groove, 8, valve body, 9, circlip for hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of valve body sealing component of the present utility model, its structure comprises flap 2 and location core 4, the one side of flap 2 is a sphere, another side is the plane, has on the sphere of flap 2 and O shape circle 1 circular groove that matches 7, and the plane of flap 2 is provided with connecting rod 6, connecting rod 6 slides with the tie rod holes 5 on the core 4 of location and links to each other, the connecting rod 6 outer springs 3 that are with, an end of spring 3 links to each other with location core 4, and the other end links to each other with the plane of flap 2.
Flap 2 and location core 4 are installed in valve body 8 inner chambers, and the sphere of flap 2 cooperates with through hole on the valve body 8, and a side of location core 4 is equipped with circlip for hole 9, are used for locating a core 4 and are fixed on the valve body 8.When fluid from flap 2 one lateral register cores 4 one side flow, hydrodynamic pressure during greater than the elastic force of spring 3, fluid be able to by, when fluid during from location core 4 one side direction flaps 2 one side flow, O shape circle 1 on flap 2 spheres contacts with valve body 8 inwalls under the pressure of waterpower and spring 3, form end face seal, fluid is cut off, and plays the effect of safety check.
Except O type circle 1, be the corrosion resistant metal material in this member, between each component, can not prolonged working life greatly, strengthened the reliability and stability of sealing owing to rotten aging sticking together; And this member is easy to dismounting, all replaceable or maintenance of any component wherein, and spring 3, flap 2, location core 4 and O type circle 1 can be broken decomposition respectively, and needn't change whole sealing configuration, have saved maintenance cost.
Claims (2)
1, a kind of valve body sealing component, it is characterized in that comprising flap and location core, the one side of flap is a cambered surface, another side is the plane, has the circular groove that matches with O shape circle on the cambered surface of flap, and the plane of flap is provided with connecting rod, connecting rod slides with the tie rod holes on the core of location and links to each other, connecting rod sleeve has spring, and an end of spring links to each other with the location core, and the other end links to each other with the plane of flap.
2, valve body sealing component according to claim 1, it is characterized in that described flap and location core are installed in the body cavity, the cambered surface of flap cooperates with through hole on the valve body, and the O shape circle on the flap cambered surface contacts with valve interior wall under the pressure of external force and spring.
