Abstract
The utility model provides a valve seat structure for a regulating valve. The valve seat structure comprises a sleeve, a valve seat and a valve body, and is characterized in that the valve seat is fixedly connected with the valve body through a first bolt. The valve seat structure is simple in structure and easy to machine, the valve seat is directly connected to the valve body through a bolt, and the sleeve is connected to the valve body through a bolt, so that the valve seat and the sleeve are not relatively extruded each other, and the sleeve is not in stress contact with the valve seat; and therefore, the valve seat cannot deform, and a sealing effect of a large-caliber valve can be guaranteed for a long time.
Description
Technical field
The utility model relates to the modulating valve technical field, is specifically related to a kind of valve seat construction 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; In bigbore modulating valve, because axial force is bigger, the axial pressure that valve seat bore is also very big like this; Make the valve seat extrusion easily; Thereby can make valve produce leakage problem, because distortion causes valve seat and spool concentricity variation, valve seat also can take place block phenomenons such as spool simultaneously.
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 valve seat construction of novel modulating valve; Sleeve no longer contacts with valve seat is stressed, so just avoids valve seat to bear axial force, thereby valve seat can not produce distortion; Can make bigbore valve guarantee sealing effect for a long time, increase the service life.
The technological scheme that the utility model addresses the above problem is:
A kind of valve seat construction of modulating valve comprises sleeve, valve seat and valve body, it is characterized in that: said valve seat is connected through first bolt with valve body.
Further,
Have first bolt hole on the said valve seat, said valve seat is fixedly connected with said valve body through first bolt that passes said first bolt hole.
Again further,
Said sleeve is connected through second bolt with said valve body.
Have second bolt hole on the said sleeve, said sleeve is fixedly connected with said valve body through second bolt that passes said second bolt hole.
Be provided with the sealing gasket sealing between said valve seat and the said valve body.
The valve seat construction of the utility model is simple in structure, easy processing, and valve seat directly is connected on the valve body with bolt; Sleeve also is connected on the valve body through bolt; Do not have extruding like this between valve seat and the sleeve relatively, sleeve no longer contacts with valve seat is stressed, thereby valve seat can not produce distortion; Be specially adapted to the valve seat construction of heavy caliber modulating valve, can make modulating valve guarantee sealing effect for a long time.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 1, the valve seat construction of a kind of modulating valve of the utility model comprises sleeve 1, valve seat 2 and valve body 3, and valve seat 2 is fixedly connected through first bolt 4 with valve body 3, and sleeve 1 is fixedly connected through second bolt 5 with valve body 3.
In this example, have first bolt hole on the valve seat 2, valve seat 2 is fixedly connected with valve body 3 through first bolt 4 that passes this first bolt hole.
In this example, have second bolt hole on the sleeve 1, sleeve 1 is fixedly connected with valve body 3 through second bolt 5 that passes second bolt hole.
In this example, also between valve seat 2 and valve body 3, be provided with sealing gasket 6, valve seat 2 linked to each other with valve body 3 compression seal pads 6, guarantee sealing through first bolt 4.
In the valve gap (not shown) of modulating valve receives during the flange bolt pretightening force; The contact because sleeve separates with valve seat, do not stress each other; There is not extruding between valve seat and the sleeve relatively; The axial force that sleeve bears can not pass to valve seat, thereby eliminated that valve seat is extruded and the problem on deformation that produces can make bigbore 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.
Claims (5)
