Background technique
Flowing medium conveyance conduit is meeting accumulation dirt in long-term using process, need to remove in time.In order to take out stains easily, people have designed various pollution discharge structures, and blowdown valve is the pollution discharge structure being most widely used.The blowdown valve of prior art comprises valve body, joint, valve rod, spool and handle.The upper end of described valve body is provided with the protruding neck of hollow.Described valve rod is located in described protruding neck, and the two ends of described valve rod connect respectively described handle and spool and described rotatable handle and drive described Spool rotating.Described joint is connected on described valve body, and the outlet port of described joint is provided with stifle.Current blowdown valve comprises a handle and a stifle, and handle and stifle are two independently parts, and handle is for switch valve, and stifle is used for blocking joint outlet.The blowdown valve structure of this kind of prior art is not compact, takes up room larger.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of structure compacter, the compact type blowdown valve that takes up room little.
Technical solution of the present utility model is, a kind of compact type blowdown valve with following structure is provided, and comprises valve body, joint, valve rod and spool; The upper end of described valve body is provided with the protruding neck of hollow; Described valve rod is located in described protruding neck, and the lower end of described valve rod connects described spool; Described joint is connected on described valve body, and the outlet port of described joint is provided with stifle; The upper end dew of the upper end portion of described valve rod is put outside the upper end portion of described protruding neck; The outside of described stifle is provided with handle, and the outside of described handle is provided with described dew and puts the groove that the upper end of the upper end portion of the valve rod outside the upper end portion of protruding neck matches.
Adopt after above structure, compact type blowdown valve of the present utility model, compared with prior art, has the following advantages:
Because the outside of the handle of the stifle of compact type blowdown valve of the present utility model is provided with the groove matching with the upper end of revealing the upper end portion of putting the valve rod outside the upper end portion of protruding neck, like this, by stifle after take off in the outlet port of joint, the groove of this stifle can be linked in outside the upper end of upper end portion of valve rod, be used for being with ovable valve stem rotation, thereby carry out the switch of control of sewage disposal valve.Like this, in the time that blowdown valve cuts out, stifle is connected to the outlet port of joint for blocking joint outlet, in the time that blowdown valve is opened, stifle is connected on the upper end of upper end portion of valve rod, for the switch of control of sewage disposal valve, blowdown valve compared to existing technology, reduce these parts of handle, made blowdown valve structure of the present utility model compacter, taken up room little; And can avoid stifle arbitrarily to place after taking off and lose.
As a kind of improvement of the present utility model, the lower end of the upper end portion of described valve rod is contained in the upper end portion of described protruding neck; The cross section of the upper end portion of described valve rod is kidney-shaped; The upper end portion of described protruding neck is waist shaped hole, and a side of this waist shaped hole is provided with a side of the upper end portion to valve rod and carries out the first spacing confined planes, and the opposite side that the opposite side of this waist shaped hole is provided with the upper end portion to valve rod carries out the second spacing confined planes.Adopt after this kind of structure, the shape in the hole of the upper end portion by protruding neck is carried out spacing to the upper end portion of valve rod, and structure is simpler, and makes the structure of blowdown valve compacter.
As another kind of improvement of the present utility model, between described stifle and valve body, be provided with chain; One end of described chain is connected on described stifle, and the other end of described chain is connected on described valve body.Adopt after this kind of structure, described chain links together stifle and valve body, can avoid stifle to lose.
Also have one to improve as of the present utility model, the outer circle wall of described stifle is provided with multiple convex tendons along stifle radial projection, and the plurality of convex tendon is circumferentially uniformly distributed along stifle outer circle wall.Adopt after this kind of structure, described convex tendon has anti-skidding effect, also can increase the intensity of stifle.
