Abstract
The utility model provides a sleeve structure of a regulating valve. The sleeve structure of the regulating valve comprises a sleeve, a valve seat and a valve body and is characterized in that the sleeve and the valve body are fixedly connected by a first bolt. The sleeve structure disclosed by the utility model is simple and is easy to process. The sleeve is connected to the valve body directly by a bolt, so that the sleeve and the valve seat are not stressed and contacted, and the valve seat and the sleeve are free from relative extrusion so that the sleeve is not deformed. The sleeve structure of the regulating valve is especially suitable for the sleeve structure of a big-caliber regulation valve, the regulation valve can be guaranteed to be under the normal use state for a long term, and the service life is prolonged.
Description
Technical field
The utility model relates to the modulating valve technical field, is specifically related to a kind of tube-in-tube structure of modulating valve.
Background technique
Common telescopic modulating valve adopts valve gap gland tube, sleeve to press valve seat, valve seat to press the structure of valve body; Like this in bigbore modulating valve; Because the axial force of transmitting between sleeve and the valve seat is bigger; Make sleeve window part compressive deformation easily, thereby can make that valve produces that flow diminishes, sleeve and spool concentricity variation, problem such as stuck.
Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art; The purpose of the utility model provides a kind of tube-in-tube structure of novel modulating valve; Sleeve no longer contacts with valve seat is stressed, so just avoids sleeve to bear axial force, thereby sleeve can not produce distortion; Can make the normal user mode of the long-time assurance of bigbore valve, increase the service life.
The technological scheme that the utility model addresses the above problem is:
A kind of tube-in-tube structure of modulating valve comprises sleeve, valve seat and valve body, it is characterized in that: said sleeve is connected through first bolt with said valve body.
Further,
Have first bolt hole on the said sleeve, said sleeve is fixedly connected with said valve body through first bolt that passes said first bolt hole.
Said valve seat is connected through second bolt with valve body.
Have second bolt hole on the said valve seat, said valve seat is fixedly connected with said valve body through second bolt that passes said second bolt hole.
The tube-in-tube structure of the utility model is simple in structure, easy processing, and sleeve directly is connected on the valve body with bolt; Sleeve no longer contacts with valve seat is stressed like this; Do not have extruding between valve seat and the sleeve relatively, thereby sleeve can not produce distortion, is specially adapted to the tube-in-tube structure of heavy caliber modulating valve; Can make the normal user mode of the long-time assurance of modulating valve, increase the service life.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 1, the tube-in-tube structure of a kind of modulating valve of the utility model comprises sleeve 1, valve seat 2 and valve body 3, and sleeve 1 is fixedly connected through first bolt 4 with valve body 3.
In this example, have first bolt hole on the sleeve 1, sleeve 1 is fixedly connected with valve body 3 through first bolt 4 that passes this first bolt hole.
In this example, valve seat 2 is fixedly connected through second bolt 5 with valve body 3.Valve seat 2 has second bolt hole, and valve seat 2 is fixedly connected with valve body 3 through second bolt 5 that passes this second bolt hole.
In the valve gap (not shown) receives during the flange bolt pretightening force; Valve gap will clamp sleeve, and sleeve is because top has been fixed on the valve body, and the underpart will can not contact with valve seat again; The power of so just avoiding valve gap being passed to sleeve is passed to valve seat by sleeve again; Like this sleeve underpart because and do not have the transmission of power and be not squeezed between the valve seat, sleeve window will can not be out of shape, and can make bigbore modulating valve guarantee sealing effect for a long time.
Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think the protection domain that falls into the utility model.
