Description

A kind of waterway switching device

Technical field

The present invention relates to a kind of control gear, be meant a kind of COMM communication that switch in the water route that is applied to especially.

Background technique

Many employing rotary type ceramic spools are switched in the water route of existing sanitaryware and the lifting and pulling type switching valves are controlled, these spools all are to act directly on the water-flowing path, be subjected to the influence of variation in water pressure very big, under the hydraulic pressure condition with higher, turn bite and the tight slightly phenomenon of feel can appear in the operation ceramic valve core, and the phenomenon that requires bigger switching power could control can appear in operation lifting and pulling type switching valve, and relatively effort is switched in operation, therefore remains further improvement.

Summary of the invention

Purpose of the present invention just is to provide a kind of the operation to switch light laborsaving, waterway switching device that waterway switching is steady and audible.

For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of waterway switching device, being located at one is positioned on the valve body of flow channel, this valve body has a water intake and two water outlets, and this water intake is respectively through corresponding this two water outlet that is communicated with of two tapping holes, it is characterized in that: this waterway switching device includes fixed base and slide block, this fixed base is locked on the valve body, and this fixed base is provided with the slide rail of two symmetries, slide block is formed with the chute with this slide rail corresponding matching, make slide block this fixed base slip relatively, the below of slide block is in conjunction with a jacking block again, this jacking block compresses the valve rod that is positioned at above-mentioned valve body two tapping holes top with the slide block action with selectivity, by the mobile water outlet water route that is able to the conducting correspondence of this valve rod.

The jacking block of described slide block is provided with two guiding faces that tilt and the level between two guiding faces is pushed up sincere.

Between described fixed block and the slide block elastic component is set, this elastic component can be a kind of wind spring, and an end of this wind spring is fixed on this fixed block, and the other end then is fixed on the slide block.

Be covered with a panel on described fixed base and the slide block.

Respectively set an one-way valve on two tapping holes on the described valve body, a bead and spring are set in the inner chamber of this one-way valve, above-mentioned valve handle activity is located on this one-way valve, moves up and down the switching with the controlling non-return valve water route of this bead of start and spring by valve rod.

One water shutoff film is set between this one-way valve and tapping hole, on this water shutoff film a spring is set, is provided with relief hole in the middle of this water shutoff film, and a side has an aperture, and the top of water shutoff film forms a chamber, make this water shutoff film below part be placed on the tapping hole, another part is positioned at the chamber of water intake, and aperture one end on the described water shutoff film communicates with water intake, and the other end communicates with the inner chamber of one-way valve, relief hole one end in the middle of the described water shutoff film is communicated with one-way valve, and the other end is communicated with water outlet.

Adopt such scheme, waterway switching device of the present invention only need promote slide block, make the jacking block selectivity start of slider bottom be positioned at valve rod on the valve body tapping hole,, can realize the switching in water route with corresponding water route of conducting and water outlet, and the present invention adopts the chute of slide block and cooperating of fixed base slide rail, and the effect of elastic component, steering force is little when operation is switched, and has the characteristics of light, laborsaving and good hand touch, and be not shifted after switching, it is clear, firm to switch gear.
