Description
Technical field
The utility model relates to technical field of petroleum extraction, is specifically related to a kind of stopcock.
Background technique
Along with the continuous progress of China's industry, the enhancing that especially petroleum production is professional, more and more higher to the requirement of special valve.In petroleum production process, usually need in the face of extreme natural condition, stopcock is as the essential tool in recovery process, and it plays extremely important effect.Current stopcock on the market, because hard sealing structure causes easily occurring wearing and tearing, causes leakage, causes needing to change stopcock frequently, cause cost of production straight line to rise.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of stopcock, by changing the structure of valve gap, utilizing setting sleeve and filler, pad etc. simultaneously, carrying out soft seal to stopcock, to promote its sealing effect.
The technical solution of the utility model is as follows:
A kind of stopcock, comprise valve casing, described valve casing is equipped with valve gap, at described valve casing built with valve rod, described valve rod is arranged with baffle plate, is provided with setting sleeve in the outer race of described valve rod, be provided with a boss at the top of described valve casing, described setting sleeve rides on described boss, and it is peripheral that described valve gap is screwed in described setting sleeve; At the outer pad being arranged with at least two superpositions of described setting sleeve, there is between pad certain gap, by bolt, described pad is fixed on described valve gap; Between described valve gap and described setting sleeve, be filled with filler, sheathed filling gland on described valve rod, described filling gland is connected with described valve gap by bolt, is connected to cock in the top end shaft of described valve rod.
Further, a depression bar is equipped with in the bottom of described filling gland, and described depression bar is installed with on described filler.
Beneficial effect: the utility model, by technique scheme, not only improve the sealing of stopcock, and its structure can adapt to mining conditions, have stronger practicability.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the stopcock disclosed in the utility model embodiment.
Numeral and the corresponding part title represented by letter in figure:
1, valve casing; 2, valve gap; 3, valve rod; 4, baffle plate; 5, boss; 6, setting sleeve; 7, pad; 8, filler; 9, filling gland; 10, cock; 11, depression bar.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
A kind of stopcock, comprises valve casing 1, described valve casing 1 is equipped with valve gap 2, at described valve casing 1 built with valve rod 3, described valve rod 3 is arranged with baffle plate 4, is provided with setting sleeve 6 in the outer race of described valve rod 3, by described setting sleeve 6, the location to described valve rod can be realized.
A boss 5 is provided with at the top of described valve casing 1, described setting sleeve 6 rides on described boss 5, it is peripheral that described valve gap 2 is screwed in described setting sleeve 6, like this, described valve gap 2 can form one with setting sleeve 6, be fixed on described valve casing 1, described valve gap 2 can also play the effect of fixing described valve rod 3 further simultaneously.
At the outer pad 7 being arranged with two superpositions of described setting sleeve 6, between pad 7, there is certain gap, filler can be added in this gap, form soft sealing structure, by bolt, described pad 7 is fixed on described valve gap 2, described like this pad 7 can form protection to described valve gap 2, can also effectively prevent medium from leaking simultaneously.
In order to further lift-off seal structure, the present embodiment is also filled with filler 8 between described valve gap 2 and described setting sleeve, sheathed filling gland 9 on described valve rod 3, described filling gland 9 is connected with described valve gap 2 by bolt, pressed by described filling gland 9 pairs of fillers, it is made to keep certain pressure, such filler 8 can fully be filled between valve gap 2 and setting sleeve, in order to the mechanism that user can be allowed more clearly to understand filling gland 9, the present embodiment can be equipped with a depression bar 11 in the bottom of described filling gland, described depression bar is installed with on described filler 8, make described filler by abundant compacting.
Cock 10 is connected in the top end shaft of described valve rod 3, in using process, by the rotation of valve rod 3, drive described baffle plate 4 to rotate, medium is flowed out from described cock 10, by increasing different sealing configurations on valve casing, valve gap, improve its sealing, meanwhile, because filler has certain permeability, different temperature and pressure requirements can be met, there is stronger practicability.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
