Utility model content
To solve the above problems, the utility model proposes a kind of materials'use amount is few, good seal performance utilizes material bullet
Property realize sealing valve seal plug.
The valve seal plug of the utility model design, including cock body, plug body central is equipped with the valve opening of perforation, the cock body
It is mainly made of support portion and seal compression portion, seal compression portion is more than the dish-like structure of support portion for diameter, passes through setting
Annular slot on cock body outer wall is connect with support portion, and the outer diameter of annular slot is again smaller than the outer diameter of support portion, seal compression
50 ° -70 ° of the first angle is equipped between the outer wall in portion and annular slot outer wall, and cavity is formed on the outside of annular slot.It is this
The characteristics of structure, is designed using the angle between seal compression portion and annular slot, increases sealing cavity, utilizes external structure
Elastic packing is formed to the extruding in seal compression portion, so as to improve sealing effect.
Further, first angle is 60 °, and the most thick position thickness in the seal compression portion is 2-5mm.By
In the design for using the first angle structure, so as to which seal compression portion thickness is enabled further to reduce, making for material is reduced
Dosage.
Further, the support portion is conical structure, is connected for 8-12 ° with the second taper by 4-6 ° of the first taper
Transition, and the second taper is connect with far from the end face where seal compression portion.First taper is best for 5 °, the second taper
It is best for 10 °, and support portion is to taper into form taper from annular slot to the end face of cock body.Pass through conical structure, energy
The elasticity of support portion is further increased, improves the service life of entire product.
Further, the valve opening inner wall is equipped with the first R slots close to the position of support portion microcephaly and forms elastic portion.Pass through
Set the first R slots that can further increase support portion elasticity so that it is compressed in vertical direction and horizontal direction is swung all with good
Good toughness and resilience.
Further, position corresponding with exterior annular card slot is equipped with the 2nd R slots, the 2nd R slots lower part in the valve opening
Conical opening is connected, the small end for forming valve opening of the outer imperial palace of conical opening, the taper of conical opening is 0 ° -20 °.2nd R slots have upper and lower ring
The twice road seal lip of formation.The elasticity of entire product can not only be increased, sealing performance is improved, contact surface can also be reduced
Product reduces the force of sliding friction with counterpart.And conical opening can be reached by the situation of external compression further to contract
To good sealing effect, and when swinging realization deflation by pressing, the structure of conical opening can more be conducive to the stream of gas
Go out.
The obtained valve seal plug of the utility model has been abandoned with close for the thickness by material itself and elasticity realization
The mode of envelope, but by multiple multiple elastic constructions of design, increase whole elasticity from structure, so as to improve sealing effect
Fruit, and extend service life.According to detection it is found that the obtained valve seal plug of the utility model compared with prior art,
By the design in seal compression portion, year leakage rate by being reduced within 8g within 12g, leakage rate reduces 30%；Pass through branch
The design of the conical structure of support part and multiple R slots so that its elasticity increases to 22N-28N from 15N-20N, and resilience performance improves
42%.
