Abstract

The utility model discloses an overflow-preventing automatic water storage valve, which is mainly composed of a valve body, a float bracket, a float, etc. The utility model is characterized in that the interior of valve body is provided with a directional starting lever which is respectively fixedly provided with a decompression overflow valve and a decompression sealing valve. The directional starting lever between two valves is sheathed with a rubber sealing ring, and the lower end of the directional starting lever is connected with the float bracket by a push-pull connecting component. The utility model has the advantages of simple structure, safe, convenient and reliable operation and long service life.

Description

Anti-overflow automatic water-storing switch valve

The utility model relates to a kind of delivery (pipe) line control gear, particularly a kind of anti-overflow automatic water-storing switch valve.

Existing automatic deposit water device, it closes the mode majority is to head on the inflow direction, shutoff is against the current only closed the water inlet by cursory buoyancy, uses back easy deformation and wearing and tearing for a long time, causes poorly sealed and produces the phenomenon of leaking and metalling run out.

It is along the inflow direction that the purpose of this utility model just is to provide a kind of mode of closing, and the safe and reliable control gear of performance--anti-overflow automatic water-storing switch valve.

Technical solution of the present utility model is: described valve is mainly by valve body, cursory support and cursory etc. the composition, cursory support is connected with cursory, be provided with the directional starting bar in the inside of valve body, on the directional starting bar, be fixed with decompression relief valve and reduced pressure sealing valve respectively, be set with the rubber sealing ring on the directional starting bar between decompression relief valve and the reduced pressure sealing valve, the lower end of directional starting bar is connected with cursory support by the push-and-pull link.

The guiding that the tool pilot hole is installed on the top of valve body is stifled.

The utility model is simple in structure, cheap, handling safety, convenience, reliable, the utility model adopts the material that meets national drinking water standard to make, and has avoided the pollution to water quality, can any direction connect supply channel, be widely applicable for the water storage box of various potable water tanks and water closet, also have corrosion-resistant, long service life simultaneously, need not automatic water-storing under the condition that the people keeps an eye on, water is closed completely automatically, the reliable advantage of anti-overflow.

Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.

Fig. 1 is the main TV structure cross-sectional schematic that the utility model is in opening state;

Fig. 2 is the main TV structure cross-sectional schematic of the utility model closed condition;

Fig. 3 is a water supply mounting structure schematic representation of the present utility model.

With reference to accompanying drawing, the utility model is mainly by valve body 1, cursory support 9 and compositions such as cursory 10, cursory support 9 is connected with cursory 10 by float pole 11, the bottom of valve body 1 adopts positioning dowel to be connected with cursory support 9, be provided with the guiding stifled 2 of tool pilot hole on the top of valve body 1, in valve body 1, be provided with directional starting bar 3, the upper end of directional starting bar 3 places the pilot hole of guiding stifled 2, on directional starting bar 3, be fixed with reduced pressure sealing valve 5 and decompression relief valve 4 respectively, on the directional starting bar 3 between decompression relief valve 4 and the decompression relief valve 5, be set with and go up, mobile down rubber sealing ring 6, the lower end of directional starting bar 3 is connected with the upper end that places valve body 1 push-and-pull link 7 outward, and the lower end of push-and-pull link 7 is connected with cursory support 9 by positioning dowel 8; Valve body 1 is provided with water inlet 12 and arch osculum 13.

Working procedure of the present utility model is: cursory is the opening state of valve when sagging, the water that comes of supply channel flows into through the water inlet, flow in the tank from the arch osculum, when water level reaches required moisture storage capacity, cursory come-up, move down by cursory support and push-and-pull link pulling directional starting bar, make reduced pressure sealing valve and rubber sealing ring close valve automatically closely along the inflow direction, reached the anti-overflow effect, because cursory pulling force and pressure of supply water have played the effect of throttle down jointly, this moment is cursory, cursory supports etc. are all stressed less, therefore prolonged working life.

When the drawdown in the container, cursory whereabouts naturally, upwards promote the directional starting bar by cursory support, drive on reduced pressure sealing valve and the decompression relief valve and move, just produced gap between reduced pressure sealing valve and the rubber sealing ring this moment, make water by the relief valve that reduces pressure, in the inflow tank, come water, just can boost the rubber sealing ring through after the overflow, open valve, continue water storage.So circulation is gone down, and has just realized the function of anti-overflow automatic water-storing switch valve.

Claims

1, a kind of anti-overflow automatic water-storing switch valve is made up of valve body (1), cursory support (9) and cursory (10) etc., and cursory support (9) is connected with cursory (10), it is characterized in that being provided with in the inside of valve body (1) directional starting bar (3); On directional starting bar (3), be fixed with decompression relief valve (4) and reduced pressure sealing valve (5) respectively, on the directional starting bar (3) between decompression relief valve (4) and the reduced pressure sealing valve (5), be set with rubber sealing ring (6).The lower end of directional starting bar (3) is connected with cursory support (9) by push-and-pull link (7).

2, anti-overflow automatic water-storing switch valve as claimed in claim 1 is characterized in that being equipped with on the top of valve body (1) guiding stifled (2) of tool pilot hole.
