Abstract
The utility model relates to a glue hanging sealing double-spring butterfly type stop valve. An inward-convex shoulder is coaxially arranged in the middle inside a valve body, and a layer of rubber valve seat is arranged on the convex shoulder and the inner wall of the valve body in an additional pouring mode. The two axial ends of the rubber valve seat extend out of the valve body and are provided with outer flanging to enhance the sealing performance of the valve seat and prevent the valve seat from moving axially. A fixing beam is fixedly installed at one diameter position in the middle of the inward-convex shoulder, a main shaft parallel to the fixing beam is fixedly installed inside a valve body on the axial right side of the fixing beam, an upper valve clack and a lower valve clack are symmetrically and elastically hinged to the main shaft and respectively rotate relatively around the main shaft, and the periphery of the upper valve clack and the periphery of the lower valve clack are in sealing fit with the valve seat. The glue hanging valve seat formed in a casting mode is adopted, the outer flanging fixedly connected with the valve body is integrally arranged on the end portion of the valve seat, the axial stability and sealing precision of the valve seat can be effectively guaranteed, the problem of valve seat loosing caused after the high-strength double-spring butterfly type stop valve is used for a long time is avoided, and the service life of the valve is prolonged.
Description
Technical field
The utility model belongs to valve field, especially a kind of kiss-coating sealing dual spring butterfly stop valve.
Background technique
Butterfly stop valve claims again butterfly check valve, and its effect is only to allow medium to flow to a direction, and stops direction to flow.Common this valve is automatic operation, and under the mobile fluid pressure action of direction, flap is opened; When fluid flows, by the flap of coincidence certainly of hydrodynamic pressure and flap, act on valve seat in the other direction, thereby cut off, flow.But current stop valve can only be arranged on horizontal pipe, rely on flap deadweight to block runner, the action of damming is slower, and sealing is poor.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of kiss-coating reasonable in design, simple in structure, easy to operate, long service life to seal dual spring butterfly stop valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of kiss-coating sealing dual spring butterfly stop valve, it is characterized in that: comprise valve body, rubber valve seat, fixed beam, upper flap, lower Disc, main shaft, positioning rod and torque spring, valve body is a cylinder barrel shaped structure, in this valve body, middle part is coaxially shaped with internal shoulder, this convex shoulder and valve interior wall all attached cast are shaped with one deck rubber valve seat, the axial two ends of this rubber valve seat extend to outside valve body and are shaped with flanging, strengthen the sealing of valve seat and prevent from moving axially; One diametrical position at described internal shoulder middle part is fixed with a fixed beam, the axial left side of fixed beam is water inlet direction, fixed beam sidewall towards water inlet direction is made as symmetrical water conservancy diversion inclined-plane, in the valve body on the axial right side of this fixed beam, be fixed with a main shaft parallel with fixed beam, on this main shaft, symmetrical elasticity is hinged with flap and lower Disc, on this, flap is with lower Disc respectively around the relative rotation of main shaft, and the outer rim of upper flap and lower Disc all coordinates with valve base sealing.
And, in the valve body on described main shaft right side, be fixed with a positioning rod parallel with main shaft, on main shaft, spacer sleeve is equipped with two torque springs, the two ends of one of them torque spring press-fit respectively and are fixed on flap and positioning rod, and the two ends of another torque spring press-fit respectively and are fixed on lower Disc and positioning rod.
And the reinforced block hinge that described upper flap and lower Disc are fixedly mounted with by a plurality of intervals is respectively contained on main shaft.
Advantage of the present utility model and good effect are:
1, the utility model adopts the Double-disc type structure of symmetrical hinge dress, according to pipeline flow, opens respectively, dams, stop effective, and fast response time.
2, flap of the present utility model is all provided with powerful torque spring, increases rebound velocity, guarantees sealing and the cutout speed of response of stop valve, lift line Security.
3, valve seat of the present utility model and valve body adopt integrally casting moulding, and stabilized structure, can be arranged in vertical pipeline, the valve seat distortion that is difficult for getting loose, and overall mechanical properties is strong, long service life.
4, the utility model adopts the kiss-coating valve seat of moulding by casting, valve seat end one is shaped with the flanging affixed with valve body, can effectively guarantee axial stability and the sealed precision of valve seat, avoid because of the long-term loosening problem of valve seat that causes of using, extend valve working life.
5, the utility model response quick action that dams, good seal performance, and also simple in structure, easily to control, valve part reliability is high, long service life.
