Description
Technical Field
The invention belongs to the technical field of water-saving equipment, and particularly relates to an anti-freezing valve.
Background
In winter, the severe cold temperature easily makes the water pipe frost crack, has brought considerable trouble and loss for our life, and the current solution is as follows: 1. use of more antifreeze materials; 2. the water pipe goes underground as much as possible; 3. wrapping with heat insulating material; 4. Closing the gate empties the water in the water pipe, etc.
Existing solutions for solving the frost cracking of water pipes have defects in different degrees, such as the fact that materials always have tolerance limits and the price of the materials which are more anti-freezing is higher, the water pipes always expose out of the ground, and when heat insulation materials cannot play a good heat insulation effect, the closing of a gate to empty the water pipes needs complex operation steps and waste of clean water sources can be caused in the process. Under the condition that the existing solutions can not well meet the requirements, the breakage of the water pipe not only can bring great troubles to families, but also can cause water source waste to a greater extent.
Disclosure of Invention
The invention aims to provide an antifreezing valve to solve the problem of frost cracking of a water pipe caused by cold weather.
The technical solution for realizing the purpose of the invention is as follows:
an antifreezing valve comprises an inflation device, a one-way valve and a three-way valve; the inflation device is arranged at a first connector of the three-way valve, and the one-way valve is arranged inside the connector and is positioned at the rear end of the inflation device; the conduction direction of the one-way valve is that the inflation device flows to the inner cavity of the three-way valve, gas can flow from the inflation device to the interior of the three-way valve through the one-way valve, and meanwhile liquid can be prevented from flowing to the inflation device from the three-way valve; and the other two interfaces of the three-way valve, wherein the second interface is connected with the water pipe, and the third interface is connected with the water tap.
Compared with the prior art, the invention has the following remarkable advantages:
(1) the antifreezing valve is simple and convenient to operate: the antifreezing effect can be achieved only by filling a proper amount of gas into the antifreezing valve.
(2) The antifreezing valve is simple and convenient to install: the problem of expansion with heat and contraction with cold caused by water stored in the water pipe in winter can be solved only by installing the valve in the middle of the connection of the water faucet and the water pipe.
(3) The antifreezing valve disclosed by the invention is low in cost, the existing pipe does not need to be replaced, the use of a pipe body heat-insulating material is reduced, the service life of a water pipe is prolonged, the frost cracking probability is reduced, and materials and water sources can be saved.
The present invention is described in further detail below with reference to the attached drawing figures.
Drawings
Fig. 1 is a schematic sectional view of the antifreeze valve of the present invention.
Detailed Description
For the purpose of illustrating the technical solutions and technical objects of the present invention, the present invention will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the antifreeze valve of the present invention includes an inflator 1, a check valve 2, and a three-way valve 3; the inflation device 1 is arranged at a first connector 3-1 of the three-way valve 3, and the one-way valve 2 is arranged inside the connector and is positioned at the rear end of the inflation device 1; the conduction direction of the one-way valve 2 is that the inflator 1 flows to the inner cavity of the three-way valve 3, gas can flow from the inflator 1 to the interior of the three-way valve 3 through the one-way valve 2, and liquid can be prevented from flowing to the inflator 1 from the three-way valve 3; and the other two ports of the three-way valve 3 are connected with a water pipe through a second port 3-2 and a faucet through a third port 3-3.
Furthermore, the rear end of the one-way valve 2 is connected with a gas conduit 4, and the gas conduit 4 extends into the second port 3-2 of the three-way valve 3, so that the gas flow can be better guided to the second port 3-2.
Further, in order to facilitate the installation of the antifreezing valve 3 and the inflation device 1, the axial direction of the second port 3-2 is the same as the axial direction of the third port 3-3, and the axial direction of the first port 3-1 is perpendicular to the axial directions of the second port 3-2 and the third port 3-3; the second connector 3-2 is positioned at the upper end of the three-way valve 3 and is connected with the water tap through threads; the third interface 3-3 is positioned at the lower end of the three-way valve 3 and is connected with a water pipe through threads.
In some embodiments, the inflator 1 is a valve core, and the liquid level can be pressed below the ground by manual inflation through air pressure applied to a water pipe at the lower end of the three-way valve 3.
In some other embodiments, the inflator 1 is an inflator, and the liquid level can be pressed below the ground by electrically applying air pressure to a water pipe at the lower end of the three-way valve 3.
When the anti-freezing valve is used, the anti-freezing valve is connected with a water pipe, air is pressed into the anti-freezing valve through the inflator, all water in the pipeline is lowered to the ground through the one-way valve by the air, and the water in the water pipe positioned at the upper end of the ground surface is prevented from being frozen by utilizing the ground for freezing.
