Technical Field

The invention relates to the technical field of valves, in particular to a water-stop self-closing valve.

Background

Due to the shortage of water resources, the way of supplying water in limited time is adopted by more and more places. The phenomenon of water leakage caused by forgetting to close the water faucet happens occasionally, so that not only is precious water resource wasted, but also the residential building is flooded inevitably. People have been dedicated to research on water faucets (or valves) which are self-closed when water is cut off for years, so as to solve the problems of water resource waste and flooding of residences. However, most of the self-closing faucets or valves which are shut off are not accepted by the user due to their complicated structure or their high price.

Disclosure of Invention

The invention aims to provide a water-cut-off self-closing valve to solve the problems in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

a main valve seat and a floating main valve core matched with the main valve seat are arranged in the valve body, a water inlet positioned above the main valve core and a water outlet positioned below the main valve core are arranged on the outer wall of the valve body, the water outlet is connected with a tap water valve, an exhaust valve core frame is arranged at the top of the inner wall of the valve body, an exhaust valve seat communicated with the outside is arranged at the top of the exhaust valve core frame, a floating exhaust valve core matched with the exhaust valve seat is arranged in the exhaust valve core frame, a capillary pipeline communicated with the upper part and the lower part of the main valve seat is arranged on the main valve seat, and a flow regulating valve is arranged.

Preferably, the flow control valve is a needle valve.

Preferably, the flow regulating range of the flow regulating valve is 2 ml-5 ml/min.

Preferably, a separation net is arranged in the valve body and is positioned between the exhaust valve core frame and the water inlet.

Preferably, the upper end of the capillary pipeline is connected with an extension pipe.

Preferably, the floating main spool and the floating vent spool are both spherical.

Compared with the prior art, the invention provides a water-stop self-closing valve which has the following beneficial effects:

1. the valve core shaft closing device is simple in structure and low in cost, does not use a spring as a pressure execution element, and is completely closed by the gravity of the valve core shaft, so that the closing force is constant, and the valve core shaft closing device cannot lose effectiveness with long-time use.

2. The self-closing function of the invention does not depend on the state of the water tap, and the self-closing function can be realized when water comes no matter the water tap is in an opening state or a closing state during water cut.

3. The invention can slowly drip water (with the flow rate of 2-5 ml/min) from the faucet when water comes, can remind a user of water coming, and avoids the user from repeatedly checking whether water comes or not.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, the invention discloses a water stop self-closing valve, which comprises a valve body 1, wherein a main valve seat 2 and a floating main valve core 3 matched with the main valve seat 2 are arranged in the valve body 1, a water inlet 4 positioned above the main valve core and a water outlet 5 positioned below the main valve core are arranged on the outer wall of the valve body 1, the water outlet 5 is connected with a tap water valve 6, an exhaust valve core frame 7 is arranged on the top of the inner wall of the valve body 1, an exhaust valve seat 8 communicated with the outside is arranged on the top of the exhaust valve core frame 7, a floating exhaust valve core 9 matched with the exhaust valve seat 8 is arranged in the exhaust valve core frame 7, a capillary pipeline 10 communicating the upper part and the lower part of the main valve seat 2 is arranged on the main valve seat.

Specifically, the flow regulating valve 11 is a needle valve, which can realize accurate regulation of the flow of the capillary pipeline 10.

Specifically, the flow regulating range of the flow regulating valve 11 is 2 ml-5 ml/min, a user can regulate the flow regulating valve 11 according to the pressure of a tap water pipeline, the flow of the capillary pipeline 10 is ensured to be proper, if the living floor of the user is low, the small flow regulating valve 11 can be properly regulated, and if the living floor of the user is high, the large flow regulating valve 11 can be released and regulated.

Specifically, a separation net 12 is arranged in the valve body 1, the separation net 12 is positioned between the exhaust valve core frame 7 and the water inlet 4, and the arrangement of the separation net 12 can avoid mutual interference between the floating main valve core 3 and the floating exhaust valve core 9.

Specifically, an extension pipe 13 is connected to the upper end of the capillary tube 10 to prevent sand particles flushed by tap water from blocking the capillary tube 10.

Specifically, floating main spool 3 and floating vent spool 9 are both spherical.

When the valve is used, the valve is connected in series behind a water meter of a user, and the valve core shaft is ensured to be vertically installed.

When water supply is not cut off, the floating main valve core 3 and the floating exhaust valve core 9 are both in a floating state, the main valve seat 2 is in an open state, and the exhaust valve seat 8 is in a closed state, so that water can be discharged from the faucet normally.

When water supply is stopped, the floating main valve element 3 and the floating exhaust valve element 9 fall down due to gravity, the main valve seat 2 is in a closed state, and the exhaust valve seat 8 is in an open state.

When water comes again, the water pressure forces the floating main valve core 3 to be tightly attached to the main valve seat 2, the effect of self-closing when water cut-off is achieved, meanwhile, the exhaust valve seat 8 starts to exhaust, when the gas in the valve body 1 is exhausted, the floating exhaust valve core 9 floats upwards, the exhaust valve seat 8 is in a closed state, at the moment, the water in the valve body 1 slowly flows to the faucet from the capillary, the water dripped by the faucet reminds a user of water coming, at the moment, the user closes the faucet, after the space between the main valve seat 2 and the faucet is filled with water, the pressure on two sides of the floating main valve core 3 is level, the floating main valve core 3 floats upwards, the self-closing state is removed, and at the moment, the.
