Abstract

The invention provides a valve. The valve comprises a valve rod, a regulating rod and a valve element, wherein a handle is connected at the upper end of the regulating rod; a valve cover is mounted on the valve body; a supporting rod is arranged at the lower end of the regulating rod; the valve element is fixedly connected at the lower end of the supporting rod; a pressure cavity for allowing the valve element to be placed and slide is formed between the valve body and the valve cover; side lugs are symmetrically arranged at the two sides of the valve element; a valve plug is arranged at the lower end of the valve element; a valve seat matched with the valve plug is arranged on the lower part of the valve body; and a pressure storage cavity is formed between the valve seat and the valve plug. The valve has the advantages and the positive effects that the valve plug is arranged at the lower end of the valve element, the valve seat matched with the valve plug is arranged on the lower part of the valve body, and the pressure storage cavity is formed between the valve seat and the valve plug, so that the valve plug can be prevented from jamming during movement. During throttling, the regulating rod pushes the valve element to descend, and presses the valve plug to squeeze into the valve seat, so that a fluid is completely cut off, and the sealing effect is good.

Description

A kind of valve
Technical field
The invention relates to pipeline fluid current velocity controller field, especially a kind of valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, and the sealability of valve when controlling flow must reach very high height and could meet its effect.Existing valve mechanism is too single, and the sealing effect of valve is bad, often exosmose occurs, and causes valve cisco unity malfunction.Person not only brings and reveals loss, also reduces the efficiency of work.
Innovation and creation content
The problem that the invention will solve is to provide a kind of valve, good seal performance, and structure is simple, and cost of production is low.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is: a kind of valve, comprise valve body, adjustable lever, spool, the upper end of described adjustable lever is connected with handle, described valve body is provided with valve gap, and described adjustable lever lower end is provided with strut, and the lower end of described strut is connected with spool, being provided with one between described valve body and described valve gap supplies described spool to place the pressure chamber of slippage, and the bilateral symmetry of described spool is provided with picks up the ears; The lower end of described spool is provided with valve plug, and described valve body lower portion is provided with the valve seat matched with described valve plug, is provided with pressure-storing cavity between described valve seat and described valve plug.
Further, the upper end of described valve plug portion is cylinder, and lower end is cone boss.
Further, described strut is for falling " Y " font.
Further, the internal surface of described valve seat is vertically arranged with some grooves, is provided with the second seal ring in described groove.
Further, the bottom of described valve gap and described contacting point of picking up the ears are provided with the first seal ring.
Further, described first seal ring and described second seal ring are O RunddichtringO.
Further, the quantity of described groove is no less than 3.
The advantage that the invention has and good effect are:
1. the invention is provided with valve plug in the lower end of spool, and valve body lower portion is provided with the valve seat matched with valve plug, is provided with pressure-storing cavity between valve seat and valve plug, when valve plug can be avoided to move, bite phenomenon occurs.During throttling, adjustable lever promotes spool and declines, and compressing valve plug is filled in valve seat, thoroughly blocks fluid, good sealing effect.
2. the internal surface of valve seat is vertically arranged with some grooves, is provided with the second seal ring in described groove, plays good sealing effect
Accompanying drawing explanation

Structural representation when Fig. 2 is the valve opening of the invention.
In figure:
1, valve body; 2, adjustable lever; 3, handle; 4, strut; 5, spool; 51, pick up the ears; 6, the first seal ring; 7, the second seal ring; 8, valve plug; 9, valve seat; 10, pressure-storing cavity; 11, valve seat; 12, pressure chamber; 13, valve gap
Embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As shown in Fig. 1 ~ 2, a kind of valve, comprises valve body 1, adjustable lever 2, spool 5, the upper end of described adjustable lever 2 is connected with handle 3, described valve body 1 is provided with valve gap 13 by bolt, and described adjustable lever 2 lower end is provided with strut 4, and described strut 4 is for falling " Y " font.The lower end of described strut 4 is connected with spool 5, being provided with one between described valve body 1 and described valve gap 13 supplies described spool 5 to place the pressure chamber 12 of slippage, the bilateral symmetry of described spool 5 is provided with picks up the ears 51, when spool 5 moves, 51 to be blocked by picking up the ears, bottom and described 51 contacting points of picking up the ears of described valve gap 13 are provided with the first seal ring 6, play sealing effect.
The lower end of described spool 5 is provided with valve plug 8, and described valve body 1 bottom is provided with the valve seat 9 matched with described valve plug 8, is provided with pressure-storing cavity 10 between described valve seat 9 and described valve plug 8.Further, the upper end of described valve plug portion 8 is cylinder, and lower end is cone boss.The internal surface of described valve seat 9 is vertically arranged with some grooves, is provided with the second seal ring 7 in described groove.The quantity of described groove is no less than 3.
In an embodiment of the invention, described first seal ring 6 and described second seal ring 7 are O RunddichtringO.
The working principle of the invention: during throttling, adjustable lever 2 promotes spool 5 and declines, and compressing valve plug 8 is filled in valve seat 9, thoroughly blocks fluid, good sealing effect.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
