Abstract
The invention relates to an elastic thin-wall valve seat for a big-flow high-pressure valve. The elastic thin-wall valve seat for the big-flow high-pressure valve comprises a valve seat base, a metal thin-wall cylinder and a spacing body, wherein the spacing body is fixedly arranged on the valve seat base; the metal thin-wall cylinder is fixedly arranged on the spacing body; a contact surface between the spacing body and a valve plug is a conical surface; and the metal thin-wall cylinder and the valve plug of a mushroom valve form a sealing pair after the metal thin-wall cylinder generates elastic deformation. The metal thin wall is adopted to realize sealing by the valve seat disclosed by the invention, the elastic thin-wall valve seat for the big-flow high-pressure valve has the advantages of wide use range and simple structure, the valve structure size is effectively reduced, and the service life is prolonged. Because the metal thin-wall cylinder is adopted for sealing, the valve seat of the mushroom valve and the metal thin wall are mutually acted under the action of external force, the metal thin-wall cylinder and the valve plug of the mushroom valve form the sealing pair after the metal thin-wall cylinder generates the elastic deformation, and the tightness is more easily guaranteed under the acting force of a working medium.
Description
Technical field
The present invention relates to the elastic thin-wall valve seat under a kind of bacterium valve valve the elastic thin-wall valve seat, particularly large flow condition.
Background technique
In the Mass flow system, the bacterium valve simply is widely adopted owing to its structure and control system.The sealing of bacterium valve core and valve seat comes into one's own day by day in the how to do well Mass flow system.The valve seat form of at present large flow bacterium valve mainly contains two kinds: a kind of is non-metal composite valve seat, adopt nonmetal sealing block by structure and metallic matrix formation composite valve seats such as pressure unit or spiders, good sealing effect, but because the use of nonmetal seal element restriction can not be applied in high temperature, low temperature, the corrosivity pipe-line system; Another kind is the metal sealing valve seat, comprise secondary two kinds of plane and conical surface seal, but because the restriction of metal to metal seal characteristic, the metal sealing valve base sealing is poor, and can occur after valve repeatedly uses wear and tear, chew, the situations such as metal fillings even interlock, reduction valve usability.
Summary of the invention
Can't satisfy the technical problem of limiting operationg condition owing to the reason of sealing in order to solve existing valve seat, the invention provides a kind of big-flow high-pressure valve elastic thin-wall valve seat, valve seat of the present invention has the bacterium valve base of high leak tightness and usability, and is simple in structure, and processing, assembly process process is good.
Technical solution of the present invention:
Big-flow high-pressure valve elastic thin-wall valve seat, comprise valve seat matrix 3, its special way is: also comprise metal thin-wall cylinder 1 and limit body 2, described limit body 2 is fixed on the valve seat matrix, described metal thin-wall cylinder 1 is fixed on the limit body 2, described limit body 2 is the conical surface with the surface of contact of spool, and described metal thin-wall cylinder 1 occurs to form sealing pair with the bacterium valve core after the resiliently deformable.
Big-flow high-pressure valve elastic thin-wall valve seat, comprise valve seat matrix 3, its special way is: also comprise metal thin-wall cylinder 1 and limit body 2, described metal thin-wall cylinder 1 comprises heavy wall section and thin segment, described heavy wall section is fixedly connected with the valve seat matrix, the outside of described limiting stopper and heavy wall section drive fit, and the surface of contact of described limiting stopper and spool is the plane, described thin segment upper end is higher than the surface of contact of limiting stopper and bacterium valve core, and its lower end is lower than the surface of contact of limiting stopper and bacterium valve core; Described metal thin-wall cylinder 1 occurs to form sealing pair with the bacterium valve core after the resiliently deformable.
The present invention compared with prior art has following advantage:
1, valve seat of the present invention adopts metal thin-wall to realize sealing, uses extensively, and is simple in structure, effectively reduces the valve mechanism size, improves working life.
2, the present invention adopts metal thin-wall column sealed, and under external force, bacterium valve base and metal thin-wall interact, and forms sealing pair, easier assurance sealing under operation medium power with the bacterium valve core after the metal thin-wall generation resiliently deformable.
3, limit body of the present invention adopts the metal conical surface or plane that spool is supported, and when guaranteeing metal thin-wall resiliently deformable, spool valve base sealing, plastic deformation does not occur the protection metal thin-wall, improves valve working life.
4, valve seat of the present invention adopts all metal construction, has solved the use restriction of nonmetal composite valve seat, can be applied under the extreme condition such as high temperature, ultralow temperature, corrosivity.
