Description

Technical Field

[0001] The utility model relates to the technical field of control of water flow channels of gas water heaters, in particular to an integrated vertical water replenishment inlet valve that reduces leakage points. Background Art

[0002] At present, gas water heaters are important devices for household heating. The hot water obtained by combustion in existing gas water heaters has two main uses: one is for floor heating and other heating systems, and the other is for domestic hot water. Domestic hot water is generally obtained by exchanging heat between hot water and domestic cold water. Domestic hot water and heating hot water are switched by the valve core in the outlet valve. After a period of use, the existing floor heating and other heating systems will lack water and need to be replenished through a water replenishment valve. The existing water replenishment valve and the valve body are generally connected by tilted perforations, which leads to technical problems such as leakage points and complicated installation of the water replenishment valve. Utility Model Content

[0003] The utility model aims to provide an integrated vertical water replenishment inlet valve which is easy to install and reduces leakage points in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an integrated vertical water replenishment inlet valve with reduced leakage points, including a valve body, on which a water replenishment valve, a water inlet pipe, a water pump connecting pipe and a flow sensor are installed. The water replenishment valve includes a valve pipe, in which a valve stem is installed. The valve pipe is integrally formed with the valve body through a connecting pipe. A water replenishment inlet pipe and a water replenishment outlet pipe that are separated from each other are provided in the connecting pipe. The water replenishment inlet pipe and the water replenishment outlet pipe are connected through a bypass hole. The bypass hole cooperates with the valve stem to control whether the water replenishment inlet pipe is connected to the water replenishment outlet pipe. The connecting pipe vertically connects the valve body and the valve pipe at the same time; the water replenishment inlet pipe is connected to the water inlet pipe, and the water replenishment outlet pipe is connected to the water pump connecting pipe. This type of integrated vertical water supply inlet valve that reduces leakage points vertically connects the valve body and the valve pipe through a connecting pipe to form an integrated structure to reduce leakage points, and changes the traditional inclined water supply valve into a vertical installation, which not only widens the use space and facilitates installation, but also ensures the effectiveness of the water supply valve through the interconnected water supply inlet pipe and water supply outlet pipe structure that are separated from each other in the connecting pipe to ensure timely water supply function.

[0005] The water pump connecting pipe is connected to the water supply outlet pipe through the first connecting pipe integrated with the valve body, so that the cold water entering the water inlet pipe can be replenished to the water pump to replenish water for the entire floor heating and other heating systems.

[0006] The flow sensor side of the valve body is connected with a second connecting pipe, and the second connecting pipe is connected to the pressure relief valve to relieve pressure when the system water pressure is too high.

[0007] A valve bonnet is installed on the top of the flow sensor, and the valve bonnet is sealed and crimped with the third connecting tube through a pin, the third connecting tube is integrally formed with the valve body, and the pin is inserted into the connecting hole and the buckle on the outside of the third connecting tube. This installation method of the flow sensor is not only quick, but also realizes efficient sealing performance of the valve bonnet through the sealed crimping of the third connecting tube with the pin.

[0008] The outer ends of the water replenishment inlet pipe and the water replenishment outlet pipe are commonly connected with an extension pipe, and the end of the extension pipe is connected with a threaded plug to improve the expansion performance of the water inlet valve.

[0009] A reinforcing rib is arranged between the valve body and the valve pipe to improve the structural strength of the entire valve body.

[0010] By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: the connecting pipe is used to vertically connect the valve body and the valve pipe to form an integrated structure to reduce leakage points, and the traditional inclined water supply valve is changed to a vertical installation, which not only widens the use space and facilitates installation, but also ensures the effectiveness of the water supply valve by providing a water supply inlet pipe and a water supply outlet pipe structure that are separated from each other in the connecting pipe to ensure timely water supply function.
