Abstract
The utility model provides a self-closing tap stops water, the key feature is to current ordinary tap improve, sets up a piston sealing device in the lower part to set up the ejector pin at the hob lower extreme, but self-closing when stopping water under the open mode has avoided the running water that causes because of the negligence. Compared with the existing water tap, the water tap has the obvious advantages of simple structure, self-closing when water is cut off, reliable performance and the like.
Description
The utility model belongs to a kind of field of mechanical technique, is a kind of water-stopping self-closing water tap.
Existing water tap exists the deficiency that can not close automatically when cutting off the water, uses often because inadvertent causes and metals run out, floods room, waste water source.
The purpose of this utility model is a kind of water tap that can close automatically when cutting off the water under opening state of design.
The major technique measure that the utility model is taked is improved existing ordinary faucet, and a piston sealing device is set in the tap valve body cavity of resorption, and push rod is set up in the lower end of screw rod, is used for promoting the piston of piston sealing device, the passage of fetching boiling water; When cutting off the water, piston is shut the effect of closing automatically of playing with passage under the effect of spring.
Reach concrete structure composition and feature that example further specifies the utility model water-stopping self-closing water tap in conjunction with the accompanying drawings.
Accompanying drawing is represented the exemplary construction cross-sectional schematic of the utility model water-stopping self-closing water tap.
Referring to accompanying drawing, the water-stopping self-closing water tap comprises: valve body 5, screw rod 6, seal ring 4 and piston sealing device.Piston sealing device is arranged in valve body 5 cavity of resorptions, comprising: piston 10, spring 8, valve bottom 2, seal ring 1,7,9.Piston 10 passes valve bottom 2, spring 8 is housed on the piston 10, and spring 8 as base, is equipped with seal ring 1 between piston 10 external parts and the valve bottom 2 with valve bottom 2, the interior edge face of valve bottom 2 is equipped with seal ring 9, is provided with seal ring 7 between the passage at the upper end of piston 10 and valve body 5 middle parts; Be provided with push rod 3 in the lower end of screw rod 6, constitute a kind of water-stopping self-closing water tap.
Accompanying drawing is depicted as water-stopping self-closing water tap closed condition.When needing to open, earlier screw rod 6 is screwed off, seal ring 4 is shut valve body 5 central passage, and push rod 3 is depressed piston 10, and water enters piston 10 upper ends, piston 10 is again under the pressure of water, the active force that overcomes spring 8 moves down, and presses to seal ring 9 with the sealing of valve body bottom, screws on screw rod 6 again, seal ring 4 is thrown off valve body 5 central passage, and water i.e. footpath passage flows out from outlet.
During if cut off the water, piston 10 upwards moves to closed condition shown in the drawings under the effect of spring 8, thereby realizes the function of water-stopping self-closing.
This Self-closed water tap for stopping water of the present utility model provides a kind of desirable tap for people, but autoshutdown when cutting off the water under opening has blocked up exhausted owing to neglecting the phenomenon of metalling run out that causes, compare with existing tap, have the advantages such as simple in structure, water-stopping self-closing, dependable performance.
Claims (1)
1, a kind of water-stopping self-closing water tap, have valve body, screw rod, seal ring, it is characterized in that in the cavity of resorption of valve body, also being provided with piston sealing device, the piston of piston sealing device passes the valve bottom, and spring is housed on the piston, and spring is a base with the valve bottom, between piston external part and the valve bottom seal ring is housed, the interior edge face of valve bottom is equipped with seal ring, is provided with seal ring between the passage at the upper end of piston and valve body middle part, is provided with push rod in the lower end of screw rod.
