Description

Technical Field

[0001] The present invention relates to a water replenishing valve, and more specifically to a modular vertical water replenishing valve. Background Art

[0002] Currently, for the water replenishing valves connected to gas water heaters, the valve stems for controlling water replenishment are all inclined, that is, an inclined hole is drilled in the return pipe of the heating water. The communication between this inclined hole and the domestic water inlet is controlled by the water replenishing valve stem. When the heating system is short of water, domestic water is replenished into the heating system through the water replenishing valve. The structure of this kind of water replenishing valve has extremely high manufacturing difficulty and high cost. Specifically, to drill this inclined hole, a special fixture is first required, and there are problems of processing scrap. It is also difficult to control the size of the inclined hole, and the processing cost is relatively high. In order to solve the above problems, how to reduce the manufacturing cost of the water replenishing valve, improve the adaptability performance and precise water replenishing performance of the water replenishing valve is the research object of all technical personnel in this field. Summary of the Invention

[0003] The structure of the present invention is simple. The water replenishing module structure can be arbitrarily connected to the water replenishing valve body without drilling special inclined holes, and only requires modular assembly, which greatly improves the adaptability performance and the water replenishing accuracy of the product.

[0004] In order to solve the above technical problems, the technical solution of the present invention is as follows: A modular vertical water replenishing valve includes a water replenishing valve body. An inlet and an outlet are provided on the water replenishing valve body. The inlet is connected to a flow sensor. The water replenishing valve body is connected with a water replenishing module. The water replenishing module includes a first pipeline and a second pipeline connecting the water replenishing valve body; the opening and closing of the first pipeline and the second pipeline are controlled by a water replenishing valve stem, and the second pipeline is connected to a heating water replenishing outlet; the first pipeline and the second pipeline are horizontally arranged, and the water replenishing valve stem is crosswise arranged relative to the plane where the first pipeline and the second pipeline are located. This kind of water replenishing module structure not only realizes the quick connection between the water replenishing valve body and the water replenishing valve stem, that is, the control structure, avoiding the traditional drilling structure, but also forms a modular structure of the water replenishing valve stem relative to the first pipeline and the second pipeline by replacing the existing inclined hole structure with the horizontal first pipeline and the second pipeline double-flow channel structure, greatly improving the equipment interchangeability performance, installation speed, and accuracy of water replenishing flow regulation. The most beneficial technical effect is that in the traditional structure, when the water replenishing valve stem leaks and is damaged due to wear, the entire water replenishing valve needs to be replaced, while in the present invention, only the water replenishing module needs to be replaced, and the adjustment performance after replacement is the same as the original performance, realizing the arbitrary replacement and installation of the water replenishing valve.

[0005] A tubular filter screen is provided at the junction of the flow sensor, the bathroom water replenishing inlet, and the inlet. This kind of tubular filter screen can penetrate into the interior of the pipeline system, filter the water flows of the three pipelines with one filter screen, minimize the influence of the filter screen on the water flow rate, and improve the measurement accuracy of the flow sensor.

[0006] The described heating water make-up water outlet is interconnected with the water outlet and the heating water interface, so that the domestic water coming out of the heating water make-up water outlet can be smoothly replenished into the heating water system connected to the water outlet hole.

[0007] The described make-up water valve stem is perpendicular to the plane where the first pipe and the second pipe are located. This perpendicular structure design greatly reduces the space occupied by the entire make-up water valve, reduces the manufacturing cost, and is more suitable for installation in the narrow space of the gas water heater.

[0008] The described second pipe is interconnected with the third pipe and the fourth pipe. Since the function of the second pipe is the make-up water pipe, that is, the domestic water for replenishing the heating water in the second pipe can flow to other functional components through the third pipe and the fourth pipe. The third pipe is a vertical pipe, and a first expansion plug is provided at the pipe orifice. The described fourth pipe is a horizontal pipe, and a second expansion plug is provided at the pipe orifice. The expansion performance of the entire make-up water valve is improved through the first expansion plug and the second expansion plug.

[0009] The described first pipe is interconnected with the fifth pipe. The opening and closing between the fifth pipe and the fourth pipe are controlled by the make-up water valve stem. The described first pipe is horizontally arranged, and the fifth pipe is vertically arranged, forming a vertical cross structure to save installation space and reduce the manufacturing cost. A reduced-diameter pipe orifice is provided at the connection between the first pipe and the fifth pipe. This reduced-diameter pipe orifice structure reduces the make-up water flow rate, making the entire make-up water process more controllable and accurate.

[0010] The present invention adopts the make-up water module structure, which not only realizes the quick connection between the make-up water valve body and the make-up water valve stem, that is, the control structure, avoiding the traditional drilling structure, but also forms a modular structure of the make-up water valve stem relative to the first pipe and the second pipe by replacing the existing inclined hole structure with the horizontal first pipe and the second pipe double-flow channel structure, greatly improving the equipment interchange performance, installation speed, and accuracy of make-up water flow rate adjustment. The most beneficial technical effect is that in the traditional structure, when the make-up water valve stem leaks and is damaged due to wear, the entire make-up water valve needs to be replaced, while in the present invention, only the make-up water module needs to be replaced, and the adjustment performance after replacement is the same as the original performance, realizing the arbitrary replacement and installation of the make-up water valve.
