specific Embodiment approach 1

[0009] Specific embodiment one: as shown in Figure 1, Figure 2 and Figure 3, this embodiment consists of a valve body 2, a wrench 4, a connecting rod 7, a linkage arm 8, a valve stem 10, a valve ball 14, an upper valve block 17 and a lower valve block. The valve block 18 is composed of a cavity 5 in the upper part of the valve body 2, and a water outlet channel 1, a water inlet channel 13, an intermediate channel 16 and a valve block cavity 19 in the lower part of the valve body 2, and the water inlet channel 13, the intermediate channel 16. The valve block cavity 19 and the water outlet channel 1 are connected sequentially. The lower valve block 18 is set at the lower part of the valve block cavity 19, the upper valve block 17 is fixed at the upper part of the valve block cavity 19, and the wrench 4 is set at the outside of the valve body 2. On the upper side, the top of the connecting rod 7 is fixedly connected with the lower end of the wrench 4, and the lower end of the conn...

specific Embodiment approach 2

[0010] Specific embodiment two: as shown in Figure 1, the difference between this embodiment and specific embodiment one is that it adds a lock cover 11, and the lower end of the lock cover 11 is fixed to the valve body 2 on the outer periphery of the second chute 2-2 connect. Other compositions and connections are the same as in the first embodiment.

Abstract

The present invention provides a self-closing water-saving valve when cut off the water supply, relating to a valve. The aim of the invention is to resolve the problem of no ''self-closing'' function under the closing or slight opening states of the present self-closing water-saving valve when cut off the water supply. Even under the self-closing state, if meeting vibration or larger water pressure fluctuation, the problem is differnt to achieve. The lower of the inside of the inhalant canal has a ball valve base, the lower of the valve handle is connected with the top of the valve ball, a shoulder platform is set on the valve handle, one end of the coupled arm is connected with the connecting bar, the other end of the coupled arm has a plug, the top is incline, the incline of the plug is matched with the shoulder platform on the valve handle. The valve ball falls in the closing channel of the ball valve base under the impact of gravity whenever water stopping only losing water pressure, ensuring the credibility of the valve close. The invention has a simple structure, high sensitivity, completely preventing breakout accident caused by forgetting closing valve, saving water source.

Description

technical field [0001] The present invention relates to a valve. Background technique [0002] Due to the shortage of water resources, time-limited water supply is adopted in more and more places. The phenomenon of running water due to forgetting to turn off the tap happens from time to time, which not only wastes precious water resources, but also inevitably floods the houses. For many years people have been devoting themselves to the research of self-closing faucets (or valves) without water to solve the problems of wasting water resources and flooded houses. However, most self-closing faucets or valves are not accepted by users because of their complex structure, poor sensitivity or because they are more expensive. The patent number is ZL94208915.4, the authorized announcement date is October 4, 1995, the authorized announcement number is CN2209257Y, and the utility model patent name is "self-closing faucet without water". It discloses a self-closing faucet with a relat...
