Description

Valve

Technical field

This utility model belongs to valve technology field, relates to a kind of valve.

Background technology

Chinese patent (publication number: CN103939649A, publication date: 2014.07.23) discloses a kind of self-operated type stop valve, including valve body, flap, valve rod, valve gap, installs a piston cylinder between valve body and valve gap; Mainly installing a spring between piston upper surface and valve gap, piston upper chamber and piston cavity of resorption pass through communicating pipe, control valve and valve body inlet communication; Control valve to be made up of application valve body and control spool, in application valve body, be shaped with control hole, application valve body is shaped with the first outlet, the second outlet, controls valve import, the first pressure relief opening, the second pressure relief opening; Controlling valve import by communicating pipe and valve body inlet communication, the first outlet connects with piston upper chamber and piston cavity of resorption respectively with the second outlet; Controlling spool adopts manufacture four control pistons on control bar to constitute; By controlling valve, valve body import medium is introduced piston upper chamber or piston cavity of resorption, realize stop valve is opened or closed control, and according to the flow direction of medium in valve channel, control valve import is switched to and connects with valve body intake channel, there is the cutting function of the medium pipeline that two-way circulates.

In above-mentioned stop valve, in assembling process, it is necessary to spool and valve rod are assembled together, it addition, in use, spool and valve rod are also possible to there is poor fit and cause that stop valve uses unstable situation to occur.

Summary of the invention

In order to solve the problems referred to above, this utility model provides a kind of constitutionally stable valve.

The purpose of this utility model can be realized by following technical proposal: a kind of valve, it is characterised in that including: valve body, described valve body has port one and port two; Integral type and in shaft-like spool, the lower end of described spool is between port one and port two, and valve body is stretched out in the upper end of described spool.

In this valve, spool designs for integral type, and this spool achieves the effect of the valve rod in original valve and spool. In the assembling process of valve, decrease the quantity of parts so that the assembling of valve is more convenient, also saves cost. It addition, in the use procedure of valve, the structure of spool is also relatively stable, improve the structural stability in valve use procedure.

In above-mentioned valve, it is characterised in that the lower end of described spool is arranged with sealing ring, described sealing ring is connected with pad one, and described valve body has the butting section corresponding with sealing ring, and described sealing ring is positioned at below butting section.Pad one serves the effect supporting sealing ring in this valve, so that sealing ring is in use unlikely to deform, improves the sealing property of this valve so that the structure in the use procedure of this valve is more stable.

In above-mentioned valve, it is characterised in that having convex shoulder on described spool, described convex shoulder is positioned at above sealing ring, and sealing ring is resisted against on the downside of convex shoulder. Under the combined effect of convex shoulder and pad one, what sealing ring can be relatively stable is positioned at valve body, improves the stability of this valve mechanism.

In above-mentioned valve, it is characterised in that described spool is provided with jump ring or pad two, described sealing ring is resisted against on the downside of jump ring or pad two. Alternatively, jump ring or pad two also are able to play the effect of above-mentioned convex shoulder.

In above-mentioned valve, it is characterised in that being additionally provided with the spring being positioned at above sealing ring in described valve body, described spring housing is located on spool, and the lower end of described spring is resisted against on valve body, and the upper end of described spring is resisted against on spool. Arranging spring in valve body, under the action of the spring, spool is subject to thrust upwards so that the closedown of valve is more laborsaving and light, facilitates valve to use.

As essentially identical means, sealing ring may also be arranged on the top of butting section, and spring is arranged to spool is had downward thrust, can reach essentially identical effect.

In this valve, original valve rod and spool are set to the spool of integral type, improve the stability of valve mechanism, reduce production cost, improve the efficiency of assembling of valve.

Detailed description of the invention

As it is shown in figure 1, this valve includes: valve body 1, valve body 1 has port 1 and port 23, and two ports are respectively used to into water and water outlet. Being provided with integral type in valve body 1 and in shaft-like spool 4, the lower end of spool 4 is between port 1 and port 23, and valve body 1 is stretched out in the upper end of spool 4.

Being additionally provided with the spring 7 being positioned at above sealing ring 5 in valve body 1, spring 7 is set on spool 4, and the lower end of spring 7 is resisted against on valve body 1, and the upper end of spring 7 is resisted against on spool 4. Arranging spring 7 in valve body 1, under the effect of spring 7, spool 4 is subject to thrust upwards so that the closedown of valve is more laborsaving and light, facilitates valve to use.

The lower end of spool 4 is arranged with sealing ring 5, and sealing ring 5 is connected with pad 1, and valve body 1 has the butting section 1a corresponding with sealing ring 5, and sealing ring 5 is positioned at below the 1a of butting section. It addition, also have convex shoulder 4a on spool 4, convex shoulder 4a is positioned at above sealing ring 5, and sealing ring 5 is resisted against on the downside of convex shoulder 4a. Pad 1 serves the effect supporting sealing ring 5 in this valve, so that sealing ring 5 is in use unlikely to deform. Further, under the combined effect of convex shoulder 4a and pad 1, what sealing ring 5 can be relatively stable is positioned at valve body 1, improves the stability of this valve mechanism.

Alternatively, spool 4 is provided with jump ring or pad two, and sealing ring 5 is resisted against on the downside of jump ring or pad two. Jump ring or pad two also are able to play the effect of above-mentioned convex shoulder 4a.

As essentially identical means, sealing ring 5 may also be arranged on the top of butting section 1a, and spring 7 is arranged to that spool 4 is had downward thrust, can reach essentially identical effect.

In this valve, spool 4 designs for integral type, and this spool 4 achieves the valve rod in original valve and the effect of spool 4. In the assembling process of valve, decrease the quantity of parts so that the assembling of valve is more convenient, also saves cost. It addition, in the use procedure of valve, the structure of spool 4 is also relatively stable, improve the structural stability in valve use procedure.
