Abstract
The utility model provides a non-pressure sleeve structure, which comprises a sleeve, a valve seat and a valve body, wherein the valve seat is connected with the lower part of the sleeve in a sealed way, the valve body is connected with the sleeve and the valve seat in a sealed way, a valve core is positioned in the center of the sleeve, a valve rod passes through a valve cover of a regulating valve from top to bottom and is then further inserted into an inner cavity of the valve body to be fixedly connected with the valve core, and the valve core is connected with the sleeve in a sealed way. The non-pressure sleeve structure is characterized in that the sleeve is fixedly connected with the valve seat through screw threads, and the valve body, the valve seat and the sleeve are connected in a sealed way through an elastic energy accumulation sealing ring. The non-pressure sleeve structure provided by the invention has the advantages that the structure is simple, the cost is low, the processing and assembling process is simple, the elastic energy accumulation ring is adopted, each valve inner element of the valve and a cavity in the valve body are enabled not to bear the downward pressure, the inner leakage caused by deformation is avoided, and the non-pressure sleeve structure is particularly suitable large-caliber valves.
Description
Technical field
The utility model relates to valve mechanism, is specifically related to a kind of pressure-free type tube-in-tube structure.
Background technique
Modulating valve is in flow liquid process control system, with power operation, to change the device of fluid flow, it is requisite control terminal in control system, the performance quality of modulating valve directly has influence on the overall performance of system, how to guarantee that it is vital that valve normal operation is not leaked.Valve body lumen, valve seat and the sleeve of existing modulating valve all needs to bear very large pressure, so that its distortion and cause interior leakage, and impact is used; Particularly, for large bore valves, because pressure is directly proportional with compression area, the power that need to bear is very large, so in valve design, the trims such as common valve body lumen, valve seat and sleeve can design very thickly, with anti-deforming.But actual service condition is also bad, still has the generation of deformation, and cause interior leakage at part weakness, is badly in need of new structure and changes the status quo.
Model utility content
The utility model completes in order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of pressure-free type tube-in-tube structure for modulating valve, can make the trims such as valve body lumen, valve seat and sleeve without bearing pressure, can not cause its distortion and cause interior leakage, guarantee the Long Service Life of valve.
The technical solution of the utility model is:
A kind of pressure-free type tube-in-tube structure, the valve seat that comprise sleeve, is connected with the lower seal of described sleeve and the valve body being connected with valve base sealing with described sleeve, spool is positioned at the center of described sleeve, valve rod is from top to bottom through further inserting body cavity after the valve gap of modulating valve, be fixedly connected with described spool, spool is connected with sleeve seal, it is characterized in that: described sleeve is threaded fixing with described valve seat; Described valve body, described valve seat and described sleeve are tightly connected by a spring energy storage seal ring.
Further, the technical solution of the utility model can also be:
The bottom of described spring energy storage seal ring is the C type that square Zhuan，Qi top is opening upwards.
The jointing place of described valve seat and described valve body and described sleeve is slightly recessed down, and the space that described spring energy storage seal ring is set is provided.
The jointing place of described valve seat and described valve body and described sleeve is slightly recessed down, and the space that arranges of described spring energy storage seal ring is provided.
The bottom of described spring energy storage seal ring compresses described valve seat; Described sleeve compresses the circle body portion of opening of C type circle on the top of described spring energy storage seal ring from top to bottom; The both sides of described spring energy storage seal ring are pushed respectively and are held out against described valve interior wall and described valve seat.
High temperature pressure-free jacket barrel structure of the present utility model is simple in structure, and cost is low, and processing and assembling is simple, and by using spring energy storage seal ring, each trim does not need to bear downward pressure, can not cause its distortion and causes interior leakage.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Of the present utility model a kind of pressure-free type tube-in-tube structure as shown in Figure 1-2, the valve seat 2 that comprise sleeve 1, is connected with the lower seal of sleeve and the valve body 3 being connected with valve base sealing with sleeve, spool 4 is positioned at the center of sleeve, valve rod 5 passes the rear further insertion body cavity of valve gap 6 of modulating valve from top to bottom, be fixedly connected with spool, spool is connected with sleeve seal, and sleeve is threaded fixing with valve seat, and valve body, valve seat and sleeve are tightly connected by a spring energy storage seal ring 7.
In this example, the bottom of spring energy storage seal ring is the C type that square Zhuan，Qi top is opening upwards.In this example, make the opening upwards setting of the C type circle body of spring energy storage seal ring.
In this example, the jointing place of valve seat and valve body and sleeve is slightly recessed down, and the space that arranges of spring energy storage seal ring is provided.
In this example, the bottom of spring energy storage seal ring compresses valve seat; Sleeve compresses the circle body portion of the opening of spring energy storage seal ring from top to bottom; The both sides of spring energy storage seal ring are pushed respectively and are held out against valve interior wall and valve seat.
On valve body of the present utility model, shallow grooves can also be set, even if the shallow grooves (not shown) of spring energy storage seal ring is held in the slightly inside recessed formation of the wall of valve body and valve seat and sleeve jointing place, guarantee good sealing effect.Use spring energy storage seal ring, can make each trim and valve body lumen all not need to bear downward pressure, can not cause its distortion and cause interior leakage, be particularly suitable for large bore valves.
Above-mentionedly only the specific embodiment of the utility model is illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think and fall into protection domain of the present utility model.
