Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a leak-proof water-gas linkage valve. Background Technology

[0002] A water-gas linkage valve is a valve device used to control the flow of water and gas. It is commonly used in water supply systems or gas pipelines. It can adjust the flow of water and gas as needed to achieve automatic control and regulation functions. Water-gas linkage valves are characterized by high flexibility, fast response speed, and simple operation. They are widely used in industrial production, building facilities, HVAC systems and other fields. By adjusting the water-gas linkage valve, the flow of water and gas in the system can be effectively controlled, ensuring stable system operation and meeting the needs of different occasions.

[0003] During the use of water-gas linkage valves, pressure fluctuations in the water or gas source may cause valve instability, affecting flow rate and overall system performance, leading to a drop in system pressure, affecting the normal flow of water or gas, reducing system efficiency, and leaking water or gas may cause safety accidents such as fires and explosions, posing dangers to personnel and equipment, or causing equipment to become damp, corroded or damaged, shortening the service life of the equipment, and causing additional maintenance and replacement costs, increasing the operating costs of the system;

[0004] Therefore, a water-gas linkage valve to prevent leakage is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof water-gas linkage valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof water-gas linkage valve, comprising a water valve and a gas valve, wherein a water supply pipe is fixedly connected to the middle right side of the water valve, and a plurality of balls are slidably arranged around the middle outer end of the water supply pipe, a connecting spring is sleeved on the outer wall of the water supply pipe, and a threaded sleeve is slidably connected to the outer wall of the water supply pipe, one end of the connecting spring is fixedly connected to the water valve, and the other end of the connecting spring is fixedly connected to the threaded sleeve, and a connecting pipe II is slidably connected to the inner wall of the water supply pipe, wherein a plurality of ball grooves are evenly opened around the outer wall of the connecting pipe near the water supply pipe.

[0007] Preferably, a water inlet pipe is fixedly connected to the middle of the front side of the water valve.

[0008] Preferably, a valve is fixedly connected to the middle of the outer wall of the water inlet pipe, and an air inlet pipe is fixedly connected to the middle of the front side of the air valve.

[0009] Preferably, a solenoid valve is fixedly connected to the outer wall of the air intake pipe, and a connecting pipe is fixedly connected to the middle left side of the air valve.

[0010] Preferably, a connecting flange is fixedly connected to the outer wall of the adjacent end of both connecting pipe one and connecting pipe two, and an output pipe is fixedly connected to the middle of the connecting flanges on both sides.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting corresponding connection and locking mechanisms for the delivery paths of the air valve and water valve, the liquid and gaseous media flowing in the delivery paths are firmly sealed. The threaded sleeve on the outer wall of the second connecting pipe is moved and then squeezed by the connecting spring on its inner wall, so that each ball can move upward a certain distance, thus satisfying the insertion of the second connecting pipe. After insertion, the threaded sleeve is released, and under the elastic force of the connecting spring, the threaded sleeve returns to its original position. Under the squeezing action of its inner wall, each ball moves downward and falls into the inner wall of the corresponding ball groove, completing the tight locking between the second connecting pipe and the water pipe. This can reduce the loss of the water-air linkage valve due to leakage and extend the service life of the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 6 An embodiment of this utility model is provided: a leak-proof water-gas linkage valve, including a water valve 1 and a gas valve 2. A water supply pipe 12 is fixedly connected to the middle right side of the water valve 1. Several balls 13 are slidably arranged around the middle outer end of the water supply pipe 12. A connecting spring 15 is sleeved on the outer wall of the water supply pipe 12. A threaded sleeve 14 is slidably connected to the outer wall of the water supply pipe 12. One end of the connecting spring 15 is fixedly connected to the water valve 1, and the other end of the connecting spring 15 is fixedly connected to the threaded sleeve 14. A connecting pipe 2 10 is slidably connected to the inner wall of the water supply pipe 12. Several ball grooves 11 are evenly opened around the outer wall of the connecting pipe 2 10 near the water supply pipe 12.

[0023] Among them: the positions and quantities of the spheres 13 and the sphere grooves 11 correspond one-to-one; the threaded sleeve 14 is set with recessed inner walls at both ends.

[0024] Even better: The threaded sleeve 14 sleeved on the outer wall of the connecting pipe 2 10 is moved to compress the connecting spring 15 set on its inner wall, so that each ball 13 can move upward a certain distance, thereby satisfying the insertion of the connecting pipe 2 10. After insertion, the threaded sleeve 14 is released, and under the elastic force of the connecting spring 15, the threaded sleeve 14 can return to its original position. Under the compression of its inner wall, each ball 13 moves downward and falls into the inner wall of the corresponding ball groove 11, thus completing the tight locking of the connecting pipe 2 10 and the water pipe 12.

[0025] A water inlet pipe 3 is fixedly connected to the middle of the front side of water valve 1. A valve 4 is fixedly connected to the middle of the outer wall of water inlet pipe 3. An air inlet pipe 5 is fixedly connected to the middle of the front side of air valve 2. A solenoid valve 6 is fixedly connected to the outer wall of air inlet pipe 5. A connecting pipe 7 is fixedly connected to the middle of the left side of air valve 2. A connecting flange 8 is fixedly connected to the outer wall of the adjacent end of connecting pipe 7 and connecting pipe 10. An output pipe 9 is fixedly connected to the middle of the connecting flanges 8 on both sides.

[0026] Among them: connecting pipe 7, connecting flange 8 and connecting pipe 10 are all symmetrically arranged with respect to the center of output pipe 9;

[0027] Even better: After the valves 4 and 6 are opened, the liquid and gas flow along the water inlet pipe 3 and the air inlet pipe 5 respectively to the interior of the water valve 1 and the air valve 2. With the cooperation of the connecting pipe 1 7 and the connecting pipe 2 10, they are stably transported to the interior of the output pipe 9. Finally, the water valve 1 and the air valve 2 are connected as one unit by the connecting flanges 8 on both sides, so as to carry out sealed and linked transport of liquid and gas.

[0028] The working principle of the above implementation is as follows:

[0029] The operation steps are as follows:

[0030] First, after the valves 4 and 6 are opened, the liquid and gas flow along the water inlet pipe 3 and the air inlet pipe 5 respectively, and are delivered to the interior of the water valve 1 and the air valve 2. The threaded sleeve 14 sleeved on the outer wall of the connecting pipe 2 10 is moved, which in turn squeezes the connecting spring 15 set on its inner wall, so that each ball 13 can move upward a certain distance, thereby satisfying the insertion of the connecting pipe 2 10. After the insertion, the threaded sleeve 14 is released, and under the elastic force of the connecting spring 15, the threaded sleeve 14 can return to its original position. Under the squeezing action of its inner wall, each ball 13 moves downward and falls into the inner wall of the corresponding ball groove 11, completing the tight locking of the connecting pipe 2 10 and the water supply pipe 12. With the cooperation of the connecting pipe 1 7 and the connecting pipe 2 10, the liquid and gas are stably delivered to the interior of the output pipe 9. Finally, the water valve 1 and the air valve 2 are connected as one unit by the connection of the connecting flanges 8 on both sides, so as to carry out sealed and linked delivery of liquid and gas.
