Abstract

The utility model relates to a single-seat regulating valve. A main body comprises a valve body, a valve cover and a valve stem, wherein a valve core is arranged between an inlet and an outlet in the valve body, and a valve seat is arranged in the middle of the inner cavity of the valve body; the upper part of the valve seat is provided with an isolating sleeve; a guide seat is arranged at an outlet on the upper part of the valve core; a guide sleeve component is arranged in the guide seat; and the valve stem penetrates through the guide sleeve component and is connected with the valve core. The single-seat regulating valve is characterized in that the connection part of the valve seat and the valve body is provided with a valve seat winding pad, and the connection part of the valve cover and the valve body is provided with a valve cover winding pad. Since the winding pads are adopted at the connection part of the valve seat and the valve body and the connection part of the valve cover and the valve body instead of original rigid thread connection in the structural design, the sealing effect of the valve can be better ensured. In case of erosive wear of the valve core and the valve seat and internal leakage, the valve can be disassembled on the site for replacement of worn parts, and needs not to be returned to a factory for repair, the delivery cost can be reduced, the working efficiency can be increased, and the working quality can be ensured.

Description

Single-seat adjusting valve

Technical field

The utility model relates to a kind of modulating valve, especially relates to a kind of single-seat adjusting valve that makes things convenient for the instantaneously changing wearing part to increase work efficiency.

Background technique

At present, the size that is applied to control flow rate in the industry and regulates flow is all used modulating valve, but in operation; The guide sleeve assembly in the modulating valve and the sealing part of valve body and valve seat, valve body and valve gap need be born bigger pressure difference, thus the seal request in the modulating valve than higher, the employing of conventional seals place all be that rigid connector such as screw thread is connected and sealed; Because the existence of pressure difference; The fixed connection of link causes the modulating valve internals to be washed away and causes that a large amount of wearing and tearing, the internals after the wearing and tearing are that supporting needs carry out depot repair, owing to can't be changed the wearing and tearing internals then and there; Like this; Not only influence working efficiency, also improved freight back and forth simultaneously, reduced manufacturing efficiency.

Summary of the invention

The utility model technical problem to be solved provides a kind of single-seat adjusting valve that makes things convenient for instantaneously changing wearing and tearing internals, increases work efficiency.

The technological scheme that its technical problem of the utility model solution is taked is: a kind of single-seat adjusting valve, main body are valve body, valve gap and valve rod, wherein, are provided with spool in the middle of the import and export in the said valve body, and the body cavity middle part is equipped with valve seat; Valve seat top is provided with spacer; Outlet port, said spool top is provided with guide holder; The guide sleeve assembly is installed in the said guide holder; Said valve rod passes the guide sleeve assembly and is connected with spool, and said valve seat and valve body joint are equipped with the valve seat wound gasket, and said valve gap and valve body joint are equipped with the valve gap wound gasket.

In order better to play sealing effect, the intensive in the form of a ring layout of said valve seat wound gasket and valve gap wound gasket is in valve gap and valve body joint and valve seat and the formation soft seal of valve body joint.

After adopting said structure, be characterized in: this structural design, adopt wound gasket to replace original screw thread rigidity be connected with valve body, valve gap with the valve body place at valve seat; Better guaranteed the sealing effect of valve, erosive wear occurred, when leaking in producing at spool, valve seat; The soft sealing structure that valve gap and valve body joint and valve seat and valve body joint form; Can after disintegrating valve, change wearing part at the scene, need not depot repair, reduce shipment and delivery cost and reach; Increase work efficiency, guarantee the purpose of workmanship.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the utility model overall schematic;

Fig. 2 is an A district enlarged diagram among Fig. 1.

Among the figure: 1, valve body 2, valve seat 3, spool 4, spacer 5, guide holder 6, valve rod 7, valve gap 8, valve gap wound gasket 9, guide sleeve assembly 10, valve seat wound gasket.

Embodiment

Fig. 1, a kind of single-seat adjusting valve shown in Figure 2, main body are valve body 1, valve gap 7 and valve rod 6, wherein, are provided with spool 3 in the middle of the import and export in the said valve body 1, and valve body 1 inner chamber middle part is equipped with valve seat 2; Valve seat 2 tops are provided with spacer 4; Outlet port, said spool 3 top is provided with guide holder 5; In the said guide holder 5 guide sleeve assembly 9 is installed; Said valve rod 6 passes guide sleeve assembly 9 and is connected with spool 3, and said valve seat 2 is equipped with valve seat wound gasket 10 with valve body 1 joint, and said valve gap 7 is equipped with valve gap wound gasket 8 with valve body 1 joint.

Said valve seat wound gasket 10 and the intensive in the form of a ring layout of valve gap wound gasket 8 form soft sealing structure at valve gap 7 and valve body 1 joint and valve seat 2 with valve body 1 joint.

This structural design adopts wound gasket to replace original screw thread rigidity be connected with valve body 1, valve gap 7 with valve body 1 place at valve seat 2, has better guaranteed the sealing effect of valve; Erosive wear occurs at spool 3, valve seat 2, when leaking in producing, can after disintegrating valve, change wearing part at the scene; Need not depot repair and reach; Reduce shipment and delivery cost, increase work efficiency, guarantee the purpose of workmanship.
