Abstract

The utility model discloses a crawl valve used for tap water switches, comprising an O-shaped sealing ring, a valve clack, a valve body, a draw rod, a spring, a spring seat, a switch wheel, a valve hood, a pressure lever and a button. The crawl valve used for tap water switches is characterized in that a push-button type is adopted, the water channel can be communicated by pushing the button, the water channel can be closed by pushing the button again, the switching is rapid, and the operation is convenient; the gravity pressure sealing is adopted, and the sealing performance is good; the service life is long; the range of application is wide, and the crawl valve can be used as a pipeline valve, or a feces flushing valve or various water faucets.

Description

Crawl valve

The utility model belongs to architectural hardware.

All there is the drawback of using inconvenience in existing stopcock, water nozzle, the spring tap that is used for running water switch, tap water could be opened or close to stopcock and water nozzle repeatedly rotation hand wheel, the speed that opens or closes is slow, and seal rubber pad is easy to wear, and threaded stem is also fragile, causes and leaks, and spring tap to press down the water nozzle shank with a hand be that path discharges water, after putting enough water, just loosing one's grip is that closed circuit cutting off the water used trouble, and the worker employed in a plant nursery is time-consuming.

It is a kind of easy to use that the purpose of this utility model is to provide, good airproof performance, durable Crawl valve.

The utility model is to adopt push button, and one presses, and flap moves down path and discharges water, and one presses again, move closed circuit cutting off the water on the flap, switch is efficient and convenient, and flap is closed except that by the spring force, also uses the pressure of tap water, promptly self-pressure-sealed, good airproof performance adopts O-ring seals, and is durable.

Further specify below in conjunction with accompanying drawing:

Fig. 1 is the Crawl valve longitudinal section that is loaded in the pipeline.

The Crawl valve longitudinal section of Fig. 2 for using when water nozzle.

Fig. 3 is this valve valve gap front view (partly cut-away).

Fig. 4 is that Fig. 3 is at A-A place sectional view.

Fig. 5 is this valve depression bar front view.

Fig. 6 is this valve depression bar plan view.

Fig. 7 is this valve key wheel front view.

Fig. 8 is this valve key wheel plan view.

With reference to Fig. 1～8, this valve is made up of O-ring seals 1, flap 2, valve body 3, pull bar 4, spring 6, spring seat 7, key wheel 8, valve gap 9 and depression bar 10, button 11.Key is taken turns 8 middle parts three long keys, top and the bottom are circle core shape, valve gap 9 profiles are nut type, there is outside thread in the skirt section, and a star-shaped aperture is arranged in the middle of the top, is circular hole in the middle of the star-shaped aperture, staggered uniform 3 short grooves and 3 elongated slots are arranged on every side, depression bar 10 is a tubulose, and there are 6 short keys in the skirt section, and end face has 6 two inclination W shape grooves, above-mentioned long key, short key, elongated slot, short groove end is the inclined-plane, O-ring seals 1 is sleeved in the flap 2 shoulder annular grooves, and flap is positioned on the valve inleting water hole, pull bar 4 vertical 3 li of the valve bodies that are contained in, the underpart is connected with flap, the middle part is with spring 6, and the spring top is a spring seat 7, and pull bar 4 upper end portions are connected with key wheel 8, valve gap 9 is positioned in the screw of valve body top, depression bar 10 is positioned on valve gap top, and the bottom is connected with sprocket wheel, and the upper end is equipped with button 11.

Characteristics of the present utility model: the one, switch is quick, and is easy to use; The 2nd, adopt self-pressure sealing good airproof performance; The 3rd, long service life; The 4th, applicability is wide, both can be used as pipeline valve, stool flushing valve, can be used as various water nozzles again.
