Abstract

The invention discloses a sleeve valve. The sleeve valve comprises a valve body, an upper valve cover is fixedly connected to the upper end of the valve body, a sleeve matched with a valve opening is installed in the valve body, a valve element is arranged in the sleeve in a sliding fit manner, and a valve rod penetrating the upper valve cover is fixedly connected to the valve element; and a carbon ring is arranged between the inner wall of the sleeve and the valve element, a winding mat is arranged between the valve body and the front end of the sleeve, packing is arranged between the upper portion of the valve rod and the valve body, and a packing gland and a packing pressing plate are pressed on the packing. According to the sleeve valve, the carbon ring is arranged between the inner wall of the sleeve and the valve element, and the winding mat is arranged between the valve body and the front end of the sleeve, so that the structural design is further optimized, and the stability and the balance are further improved.

Description

A kind of telescoping valve
Technical field
The present invention relates to valve class field, particularly belong to a kind of telescoping valve.
Background technology
Telescoping valve good stability, owing to valve plug is provided with balance pipe, it is possible to reduce medium acts on the out-of-balance force on valve plug, adds that enough valve plugs guide, is therefore not easy to cause the vibration of spool.The throttling window that telescoping valve provides has out big window and spile (ejection-type) two kinds, and the latter has reduction noise, reduces the function of resonance, improves further, can become special low noise valve.
Summary of the invention
It is an object of the invention to provide a kind of telescoping valve, structure design optimizes further, and stability and balance are improved further.
Technical scheme is as follows:
A kind of telescoping valve, include valve body, valve body upper end is fixedly connected with bonnet, the sleeve coordinated with valve port is installed in valve body, in sleeve, is sliding combined with spool, spool is fixedly connected with the valve rod through bonnet, carbon circle it is provided with between sleeve lining and spool, being provided with wound gasket between valve body and barrel forward end, be provided with filler between valve rod top and valve body, on filler, pressure is equipped with gland, hold-down grid.
Described hold-down grid is bolted to connection in valve body upper end.
The present invention, by being provided with carbon circle between sleeve lining and spool, is provided with wound gasket between valve body and barrel forward end, structure design optimizes further, and stability and balance are improved further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of telescoping valve, include valve body 1, valve body 1 upper end is fixedly connected with bonnet, 2, the sleeve 3 coordinated with valve port is installed in valve body 1, spool 4 it is sliding combined with in sleeve 3, the valve rod 6 through bonnet, 2 it is fixedly connected with on spool 4, carbon circle 7 it is provided with between sleeve 3 inwall and spool 4, it is provided with wound gasket 8 between valve body 1 and sleeve 3 front end, being provided with filler 9 between valve rod 6 top and valve body 1, on filler 9, pressure is equipped with gland 5, hold-down grid 10, and hold-down grid is bolted to connection in valve body upper end.

Claims (2)
