Abstract
The utility model relates to an elastic thin-walled valve seat of a large-flow high-pressure valve. The elastic thin-walled valve seat comprises a valve seat base body, a metal thin-walled cylinder and a limiting body, wherein the limiting body is fixed on the valve seat base body; the metal thin-walled cylinder is fixed on the limiting body; the contact surface of the limiting body and a valve core is a conical surface; and the metal thin-walled cylinder after elastic deformation forms a seal pair with the mushroom valve core. The valve seat provided by the utility model adopts the metal thin wall to realize seal, is widely used and simple in structure, effectively reduces the structural size of a valve, and prolongs the service life; and moreover, the valve seat adopts the metal thin-walled cylinder for seal, under the action of external force, the mushroom valve seat and the metal thin wall are interacted, and the metal thin wall after elastic deformation forms the seal pair with the mushroom valve core, so that sealing performance can be easily ensured under the action force of a working medium.
Description
Technical field
The utility model relates to the elastic thin-wall valve seat under a kind of bacterium valve valve elastic thin-wall valve seat, particularly large flow condition.
Background technique
In Mass flow system, the bacterium valve simply is widely adopted due to its structure and control system.In the how to do well Mass flow system, the sealing of bacterium valve core and valve seat comes into one's own day by day.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 the use restriction due to nonmetal seal element can not be applied in high temperature, low temperature, corrosivity pipe-line system; Another kind is the metal sealing valve seat, comprise secondary two kinds of plane and conical surface seal, still due to 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 metal fillings situation such as interlock even, reduction valve usability.
Summary of the invention
Can't satisfy the technical problem of limiting operationg condition in order to solve existing valve seat due to the reason of sealing, the utility model provides a kind of big-flow high-pressure valve elastic thin-wall valve seat, the utility model valve seat has the bacterium valve base of high leak tightness and usability, simple in structure, processing, assembly process process is good.
Technical solution of the present utility model:
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 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 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 resiliently deformable.
The utility model compared with prior art has following advantage:
1, valve seat of the present utility model adopts metal thin-wall to realize sealing, uses extensively, and is simple in structure, effectively reduces the valve mechanism size, improves working life.
2, it is column sealed that the utility model adopts metal thin-wall, and under external force, bacterium valve base and metal thin-wall interact, and forms sealing pair with the bacterium valve core after metal thin-wall generation resiliently deformable, more easily guarantees sealing under operation medium power.
3, the utility model limit body 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 utility model 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.

Fig. 1 is a kind of structural representation of large flow elastic thin-wall valve seat;
Fig. 2 is the structural representation of another kind of large flow elastic thin-wall valve seat.
Embodiment
As shown in Figure 1, big-flow high-pressure valve elastic thin-wall valve seat comprises valve seat matrix 3, metal thin-wall cylinder 1 and limit body 2, and limit body 2 is fixed on the valve seat matrix, metal thin-wall cylinder 1 is fixed on limit body 2, and limit body 2 is the conical surface with the surface of contact of spool 4.
As shown in Figure 2, another kind of big-flow high-pressure valve elastic thin-wall valve seat, comprise valve seat matrix 3, metal thin-wall cylinder 1 and limit body 2, metal thin-wall cylinder 1 comprises heavy wall section and thin segment, the heavy wall section is fixedly connected with the valve seat matrix, the outside of limiting stopper and heavy wall section drive fit, the surface of contact of limiting stopper and spool is the plane, the surface of contact of thin segment and heavy wall section is lower than the upper end of the surface of contact of limiting stopper and spool and the thin segment surface of contact higher than limiting stopper and spool.
Formed by valve seat matrix 3, metal thin-wall cylinder 1 and limit body 2, wherein metal thin-wall cylinder 1 adopts the high metal material processing of toughness to form, limit body 2 has two kinds of structural types, can process with metal thin-wall cylinder 1 one, the formation conical surface supports, and can adopt also that independent support style and metal thin-wall are cylindrical becomes the module composition valve seat.Design and add man-hour, the metal thin-wall cylinder will be higher than the surface of contact of spool and supporting structure, and concrete height need to be determined according to actual seal request and elastic thin-wall deformation characteristic.
