Description
Technical field
The utility model relates to a kind of production tree equipment, is specifically related to a kind of stopcock of production wellhead.
Background technique
Stopcock is widely used in industry-by-industry, especially all kinds of heavy industry, chemical industry, makes the passway on valve plug identical with the passway on valve body or separate by 90-degree rotation, realizes a kind of valve opened or close.Stopcock is best suited for and cuts off and connect medium.The valve body of common stopcock and the joint sealing of valve plug poor, easily cause the leakage of gas or liquid, and mostly adopt valve body and the cock of metal material, of long duration to get rusty easily, cock can not be rotated, the demand of people cannot be met.
Summary of the invention
For solving the problem, the utility model discloses a kind of stopcock, not only good sealing effect, and not easily getting rusty.
A kind of stopcock, comprise valve body, cock and valve gap, valve pocket is provided with in described valve body, described cock is positioned at valve pocket, the top of cock is connected with cock stem, described valve body is that alloyed steel is made, described cock is that ceramic making forms, it is cylindrical fit between described cock and valve body, the surface of contact of described cock and valve body is provided with rotary liner, described rotary liner top is also provided with seal ring, described seal ring top is provided with gland, seal ring is pressed on cock top by described gland, described cock is provided with connecting passage, the gateway size of described connecting passage and the size of valve pocket passage match.
As further improvement of the utility model, described valve gap is connected with valve body by bolt.
As further improvement of the utility model, described body top is also provided with handwheel, and described handwheel and cock stem are linked.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: valve body is that alloyed steel is made, and cock is that ceramic making forms, and not easily gets rusty; The use of rotary liner and seal ring, can realize sealing, effectively prevents from, because the leakage of gas or liquid is to the corrosion of cock and valve body, extending the working life of cock.
Accompanying drawing explanation
Fig. 1 is the utility model cut-away section structural representation.
Fig. 2 is the assembled state schematic diagram of cock and lining in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, a kind of stopcock, comprise valve body 1, cock 2 and valve gap 7, valve gap 7 is connected with valve body 1 by bolt and nut, valve pocket 3 is provided with in valve body 1, valve pocket 3 is as the Vomitory of oil gas, cock 2 is positioned at valve pocket 3, the top of cock 2 is connected with cock 8, cock 8 top is connected with handwheel (not shown in FIG.) through valve gap 7, and rotate cock 8 by rotation hand wheel, cock 8 is provided with connecting passage 9, the gateway size of connecting passage 9 and the size of valve pocket internal channel match, to reduce the fluid resistance of fluid through cock.
Valve body and cock is permanent gets rusty easily, in order to solve this problem, the valve body 1 in the present embodiment adopts alloyed steel to be made, and cock 2 adopts ceramic making to form, be cylindrical fit between cock and valve body.In order to realize the sealing between valve body and cock, prevent the leakage of gas or liquid, cock 2 with the surface of contact of valve body 1 inwall are provided with rotary liner 4, rotary liner 4 is provided with the opening matched with connecting passage 9 size in cock, oil gas gateway place in valve pocket passage, position of opening, rotary liner 4 top is also provided with seal ring 5, seal ring 5 top is provided with gland 6, seal ring 5 is pressed on cock top by gland 6, rotary liner 4 and seal ring 5 can effectively prevent because the leakage of gas or liquid is to the corrosion of cock and valve body, extend the working life of cock.
When needs open stopcock by oil gas by time, only need rotate handwheel, handwheel finally drives cock to rotate, and when in the opening on the connecting passage 9, rotary liner 4 of cock and valve pocket 3 passage, oil gas gateway coincides, valve is opened completely.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technological scheme be made up of above technical characteristics combination in any.
