Description

Technical Field

[0001] The utility model relates to the technical field of automatic constant-pressure water replenishment, in particular to an automatic water replenishment valve and an automatic constant-pressure water replenishment system. Background Art

[0002] Automatic water filling valves are widely used in the scene of automatic constant pressure water filling, which also leads to a lot of maintenance problems. Among them, the most prominent one is the replacement of filter components. Since automatic water filling directly uses municipal tap water, which contains a large amount of impurities, after a period of use, the filter components will be blocked by impurities and dirt, resulting in reduced water flow and unstable water pressure, which affects the working effect of the automatic water filling valve.

[0003] In the prior art, there are two ways to install the filter element. One is as shown in the patent (application number: CN200920211000.0): in a visually adjustable automatic water supply valve, the filter element is set at a deeper position in the valve body, and the water supply shut-off knob of the automatic water supply valve needs to be removed, which is very troublesome to replace or clean.

[0004] Another one is the patent (application number: CN202222656845.9): in an automatic water replenishment valve with filtration, an installation port is opened at the water inlet channel of the valve body, and a cylindrical filter element is vertically inserted into the water inlet channel through the installation port. This arrangement is very efficient and convenient to install and replace. However, the technical solution of this patent has the following problems: 1. Large water resistance and small water flow cross section; 2. Filtration is only achieved at the cross section corresponding to the water inlet, and the filter utilization rate is low; 3. The garbage filtered by the filter is not easy to settle to the bottom, which will cause the water flow cross section to become smaller and smaller, the maintenance and replacement cycle is short, and the use cost is high.

[0005] On the other hand, in the application scenarios of the automatic constant pressure water replenishment system of the prior art, such as the water system of HVAC, it is usually necessary to install a water pressure gauge on the pipeline to collect the water pressure, so as to determine whether water replenishment is needed. Therefore, accessories such as tees will be added, which has high installation costs, long installation cycles, and inconvenient construction. Utility Model Content

[0023] Figure 1 It is a structural schematic diagram of an automatic water replenishment valve according to an embodiment of the utility model. DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0025] First, combine Figure 1The automatic water replenishment valve according to the embodiment of the utility model is described, and its application scenarios are very wide.

[0026] like Figure 1 As shown, the automatic water replenishment valve of the embodiment of the utility model comprises: a valve body 1, a first flow channel 2, a second flow channel 3, a filter assembly 4, a switch assembly 5 and a third flow channel 6.

[0027] Specifically, Figure 1 As shown, a water inlet 11 and a water outlet 12 are provided on the valve body 1; a first flow channel 2 is provided in the valve body 1, and one end of the first flow channel 2 is connected to the water inlet 11; a second flow channel 3 is provided in the valve body 1, and one end of the second flow channel 3 is connected to the first flow channel 2; a filter component 4 is provided in the second flow channel 3, and water in the first flow channel 2 is filtered by the filter component 4; a switch component 5 is connected to the second flow channel 3, and water in the second flow channel 3 flows out from the switch component 5; a third flow channel 6 is provided in the valve body 1, and one end of the third flow channel 6 is connected to the switch component 5, and the other end is connected to the water outlet 12.

[0028] Further, if Figure 1 As shown, a first opening 21 is formed on the side of the first flow channel 2 , and the first opening 21 is connected to the other end of the second flow channel 3 .

[0029] Further, if Figure 1 As shown, a second opening 31 is formed on the side of the second flow channel 3 , and the second opening 31 is connected to the switch assembly 5 .

[0030] Further, if Figure 1 As shown, there is a gap between the second flow channel 3 and the filter assembly 4, and the filtered water flows into the gap and flows out from the second opening 31. The filter assembly 4 includes: a filter screen 41, and the filter screen 41 is cylindrical. In this embodiment, the gap between the cylindrical filter screen 41 and the second flow channel 3 allows the filter screen 41 to be fully utilized, allowing the filter screen 41 to be used for a longer time and reducing the frequency of replacement.

[0031] Further, if Figure 1 As shown, the filter assembly 4 further includes: a plug 42, which is arranged at the other end of the second flow channel 3. By opening the plug 42, the filter screen 41 in the second flow channel 3 can be disassembled and replaced. The impurities and dirt generated by the filtration will settle at the bottom of the second flow channel 3. By opening the plug 42, they can be directly cleaned, which increases the convenience of regular cleaning of the filter screen and also increases the service life of the filter screen 41.

[0032] Furthermore, the switch assembly 5 is a knob switch. The knob switch in this embodiment is used to shut off the water replenishment. It is in a normally open state under normal circumstances and is manually closed under abnormal circumstances.

A pressure gauge is installed on the external interface 7 to detect the pressure of water flowing from the water inlet 11 into the first flow channel 2. In this way, there is no need to install a pressure gauge on the pipeline, which reduces the action of connecting the pressure gauge on the pipeline, improves the pertinence and accuracy of the pressure setting; at the same time, it also saves accessories such as tees used to install pressure gauges on the pipeline, reduces installation costs, and shortens the construction period. In this embodiment, an external interface 7 can also be set at the third flow channel 6 for installing a detection instrument, such as a pressure gauge.

[0034] In this embodiment, a constant pressure assembly 13 is further provided on the valve body 1 for setting a pressure value.

[0035] During use, tap water flows in from the water inlet 11, flows through the first flow channel 2, flows out from the first opening 21 of the first flow channel 2, then flows into the second flow channel 3, is filtered by the filter 41 in the second flow channel 3, flows to the gap between the filter 41 and the second flow channel 3, then flows from the gap to the second opening 31, flows from the second opening 31 to the knob switch, and after passing through the knob switch, flows from the third flow channel 6 to the water outlet 12.

[0036] According to an embodiment of the utility model, an automatic constant pressure water replenishment system is also provided, which includes an automatic water replenishment valve. Using the automatic water replenishment valve of this embodiment, the filtering effect of tap water is better, the water replenishment effect is better, and the operation of the automatic constant pressure water replenishment system is more stable.
