Description

Rolling valve

The utility model relates to the fluid circuit valve fittings, a kind of specifically stop valve of realizing keying with the elastic rolling body.

At the fluid circuit of industry and civil area as supplying water, air feed, in the feed flow pipeline, stop valve is used to the circulation of fluid in the pilot line or ends, the valve that its structure also is applicable to pipeline terminal is water tap for example, the stop valve of present medium and small pipeline or water tap generally use the structure of spiral valve rod lifting flap, one of problem that this valve exists is that Long-time Shut-down the screw thread embroidery can occur extremely, influence working life and escape of liquid, simultaneously, during opening/shutting valve, on the handle, following motion can not be used in some limited space place, and other stop valve structure also has ball valve, plunger valve etc., the structure more complicated, service time, length also the escape of liquid problem can occur.

The purpose of this utility model provides a kind of stop valve that realize to open and close with the elastic rolling body, changes the valve rod flap structure that tradition is used, and reaches simple in structure, and few purpose is reliably revealed in applied widely, long service life, sealing.

The purpose of this utility model is achieved in that a kind of Rolling valve, and its structure comprises valve body, valve rod, valve gap, handle;

A. body cavity is a cylindrical hole, and the valve port that connects osculum and inner chamber is long narrow seam shape and valve port length direction and valve rod axis parallel;

B. valve rod is contained in the body cavity center, and its hypomere axle journal is cylindrical;

C. with compressive state the elastic rolling body is housed in the annulus between body cavity hole wall and valve rod hypomere circular shaft, this rolling element is cylindrical, make with elastic abrasion-proof material, its axis and valve rod axis parallel, when the elastic rolling body is positioned at the valve port position that aligns valve body, the compressive strain of this rolling element will connect the long narrow seam shape valve port sealing of water outlet, and make valve port be in the full cut-off state.

In preferred embodiment, described elastic rolling body is a hollow cylinder.

Described valve gap is disc, be installed in the inner chamber circular hole of valve body, on itself and the hole wall mating face O RunddichtringO is housed, the valve gap center has shoulder hole to be set in valve rod, the O RunddichtringO is equipped with on itself and valve rod mating face, described valve gap upper end is by the circlip location that is flush-mounted in the valve body hole wall, and the valve gap lower end is by the shaft shoulder location of the thick axle journal of valve rod hypomere diameter.

The appropriate location of the annulus between body cavity hole wall and valve rod hypomere circular shaft is provided with two limiting stoppers, wherein the corresponding rolling element of a limiting stopper aligns the position of valve port, this moment, valve port was in closed state, the corresponding rolling element of another limiting stopper turns to the position of leaving valve port, and this moment, valve port was in the full open state.

The utility model has following actively useful effect:

1. Rolling valve can be used for hot water or cold water, low pressure steam, chemical industry acid-and base-resisting and family's water nozzle etc. and can adopt this principle, and the frock size is with domestic various valves are the same at present.

2. the Rolling valve internal structure is simple, and without screw thread solves because of the dead problem of Long-time Shut-down quilt rust, prolongs the working life of valve, alleviates operator, miantainers' burden.

3. this valve has following evident characteristic:

1. owing to adopt the elastic rolling body to carry out valve working control.The choose reasonable decrement can reach higher control reliability and long working life.

2. owing to adopt circumferential Rolling valve, the supreme movement process down of handle during work is so handle height no change is convenient to the limited place use in the space.

3. valve rod is taked the seal with O ring installed under the compressive state, thereby can improve the reliability and the working life of sealing greatly.

4. because valve rod adopts the seal with O ring structure, the circlip structure is adopted in the valve gap location, and therefore, the height dimension of valve is less.

5. this valve moment of rotation is little, operates free and relaxed.

6. sealing is reliable, does not have and leaks, and is water-tight when being used for supply channel.

4. Rolling valve is because internal structure is simple, and domestic each valve plant all can produce in batches at present, and external form and frock size constancy only change internal structure.Other all can adopt moulding (the elastic rolling body is the rubber pattern casting die) to this valve except that valve body and circlip, thereby is convenient to produce in batches, and is with low cost.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is an a kind of embodiment's of the present utility model complete section front view.

Fig. 2 is the A-A parting view of Fig. 1.

Fig. 3 is the left side partial view of Fig. 1, shows the port shape of valve body.

Rolling valve of the present utility model, its structure comprise that valve body 1, valve rod 2, valve gap 3, handle 4 see Fig. 1;

Body cavity 5 is a cylindrical hole, and the valve port 7 that connects osculum 6 and inner chamber 5 is long narrow seam shape and sees Fig. 3 and valve port 7 length directions and valve rod 2 axis parallels;

Valve rod 2 is contained in body cavity 5 centers, and its hypomere axle journal 8 is cylindrical;

With compressive state elastic rolling body 9 is housed in the annulus between body cavity 5 hole walls and valve rod hypomere circular shaft 8, this rolling element 9 is cylindrical, make with elastic abrasion-proof material, its axis and valve rod axis parallel, when the elastic rolling body is positioned at valve port 7 positions that align valve body, the compressive strain of this rolling element will connect the long narrow seam shape valve port sealing of water outlet, and make valve port 7 be in the full cut-off state.

In preferred embodiment, described elastic rolling body 9 is seen Fig. 2 for hollow cylinder.

With reference to Fig. 1, described valve gap 3 is disc, be installed in the inner chamber circular hole 5 of valve body, on itself and the hole wall mating face O RunddichtringO 10 is housed, valve gap 3 centers have shoulder hole to be set in valve rod, O RunddichtringO 11 is equipped with on itself and valve rod mating face, and described valve gap upper end is by circlip 12 location that are flush-mounted in the valve body hole wall, and the valve gap lower end is by the shaft shoulder 13 location of the thick axle journal of valve rod hypomere diameter.

With reference to Fig. 2, the appropriate location of the annulus between body cavity hole wall and valve rod hypomere circular shaft is provided with two limiting stoppers, wherein a limiting stopper 14 corresponding rolling elements 9 align the position of valve port 7, this moment, valve port 7 was in closed state, another limiting stopper 15 corresponding rolling elements 9 turn to the position of leaving valve port, and this moment, valve port 7 was in the full open state.

With reference to Fig. 1, handle 4 is installed on valve rod 2 with nut 17, packing ring 19, in the aperture of the inner chamber 5 of valve body 1 dust cover 18 is housed, and 16 is the water inlet among the figure.

During enforcement, described valve rod 2 can use copper material or steel to make, and steel surface needs through antirust processing, and described valve body 1, valve gap 3 can adopt cast iron or copper casting to make, and described dust cover 18 can adopt metal or plastics to make.Described rolling element 9 and O RunddichtringO generally adopt elastic wear-resisting rubber to make, but for high temperature or acid, alkali use occasion, described rolling element 9 and O type circle need adopt elastic material high temperature resistant, acid-and base-resisting to make respectively.
