Abstract
The utility model discloses an automatic closing water tap when the water supply is cut off, which is composed of a housing body, an opening and closing mechanism, and a sealing machine in the direction of water pressure. The utility model which simple advantages of simple structure and high safety has the functions that the automatic closure can be carried out when the water supply is cut off, the overflow, the escape, and the leakage of water can not occur, etc.; the purpose of water saving is reached thereby.
Description
The utility model is that a kind of water-stopping self-closing water is chewed.
Now the water that generally the uses shortcoming of chewing is with phenomenons such as emitting drip water often taking place to run after a period of time, causing the waste of great lot of water resources.
The purpose of this utility model provides a kind of not only safety but also water-saving jettison gear.
Through the Searches of Patent Literature, more existing relevant patents, but compare with the utility model, concrete structure difference, technical functionality are also different.
Fig. 1 is a kind of concrete structure schematic representation of the present utility model.
Fig. 2 is the plan view of spiral cam in the utility model concrete structure (6).
Describe concrete structure of the present utility model and principle in detail below with reference to Fig. 1:
When discharging water, with hand counter clockwise direction turning handle (1), band ovable valve stem (5) and spiral cam (6) rotate, promote flap (10) and move to right, under the elastic force force action of the dynamic pressure of water and spring (11), the frictional force of generation is greater than the torsion of torsion spring (3) between spiral cam (6) and the flap (10), flap is fixed on the position, hand leaves handle (1) and also can not close, and water flows into valve pocket, chews outflow from water outlet.
When closing, clockwise direction handle with sleeve (1) drives spiral cam (6) and rotates, forward the minimum point of spiral cam (6) to, under the force action of the elastic force of spring (11) and hydrodynamic pressure, flap (10) moves to left always, seal ring (9) just stops water outlet with the blasthole sealing.
When cutting off the water, handle with sleeve (1), push flap (10) open, because of there not being the kinetic pressure of water, frictional force between spiral cam (6) and the flap (10) is less than the torsion of torsion spring (3), hand leaves handle (1), closes automatically under the elastic force effect of the torsion of torsion spring (3) and spring (11).When discharging water,, also can close automatically by aforementioned principles if cut off the water suddenly.
Technical characteristics of the present utility model is: being positioned at the switching mechanism that water exit end is made up of handle (1), position limit pin (2), torsion spring (3), seal ring (4), valve rod (5), spiral cam (6), is that frictional force that the elastic force of the kinetic pressure of the torsion that utilizes torsion spring, water and spring produces between spiral cam and flap realizes opening, closes, adjusts the water yield and closes automatically when cutting off the water.Being positioned at the direction of the pressure downstream sealing mechanism that inlet segment is made up of seal ring (9), flap (10), spring (11), is to utilize the kinetic pressure of water and the elastic force of spring to realize reliable sealing.
Claims (2)
1, the utility model is that a kind of water-stopping self-closing water is chewed.It is characterized in that the housing that it is formed by valve gap (7), valve body (8), to silk (12); The switching mechanism of forming by handle (1), position limit pin (2), torsion spring (3), seal ring (4), valve rod (5), spiral cam (6); Form by the direction of the pressure downstream sealing mechanism that seal ring (9), flap (10), spring (11) are formed.
2, water-stopping self-closing water according to claim 1 is chewed, and it is characterized in that, the water exit end in the housing has a switching mechanism.
