Description

Technical Field

[0001] The utility model relates to the technical field of water inlet valves, in particular to a water inlet valve group using a water supply valve core. Background Art

[0002] The water inlet valve group is generally used for the water supply control of the unit, and its application range is extremely wide; for example, the water inlet valve group is used in a circulating heat exchange system, a household bathroom or a household gas bathroom. A Chinese patent (application number 202410448338.7) discloses an inlet and outlet valve structure, which discloses the following technical solutions: including a water inlet valve group and a water supply valve. Among them, the water inlet valve group is respectively provided with a bathroom water inlet flow channel and a heating circulation flow channel; the water supply valve includes a valve body and a valve shaft. The valve body is arranged on the water inlet valve group, and the valve body is respectively provided with a first chamber and a second chamber that are interconnected. The first chamber is connected to the bathroom water inlet flow channel, and the second chamber is connected to the heating circulation flow channel. One end of the valve shaft passes through the first chamber and is inserted into the second chamber and is provided with a first sealing ring. The outer diameter of the first sealing ring is smaller than the inner diameter of the first chamber. When the valve shaft is inserted into the second chamber, the circumferential outer wall of the first sealing ring is pressed against the inner wall of the second chamber. This application has the effect of reducing the possibility of the sealing effect of the sealing ring being reduced. In the above-mentioned patent disclosure, if the water inlet valve group does not close the domestic water pipeline when replenishing water (no water pressure regulating valve is designed in the pipeline), multiple water channels will be mixed (domestic water and water in the water replenishment pipeline will be mixed);

[0003] Based on the above technical problems, a Chinese patent (application number 201821290980.4) discloses an isolation one-way valve. When the heating system needs to be replenished with circulating water, the water flow pushes open the hemispherical blocking block under the action of air pressure, and at the same time pushes open the isolation valve plate 11, thereby allowing the water flow to enter the heating system from the second water outlet 4. After replenishment, the water pressure decreases, and the isolation valve plate 11 is reset under the elastic force of the second spring 13, thereby closing the water inlet of the heating system. The circulating water on one side of the heating system pipe cannot open the isolation valve plate 11 due to the mismatch in the direction of the applied force, thereby ensuring that the circulating water does not flow back and mix with domestic water;

[0004] In the above technical solution, although the isolation one-way valve proposed can solve the problem of mixing multiple water channels, in actual use, there is a movable tolerance between the one-way valve and the pipe wall, and the one-way valve will rotate in the pipe wall when installed, which will cause the locking portion to be unable to effectively lock with the pipe wall due to the rotation; the one-way valve will cause movement during use, resulting in the failure of the one-way valve function, thereby affecting the normal operation of the pipeline.

[0041] In the present invention, the main pipe 1 is used to introduce, divert or lead out the fluid according to different functions, thereby realizing different bathroom, heat exchange, heating and other functions; by arranging a guide column 14 in the water supply pipe 6, the movement direction of the one-way valve group 8 can be restricted, so that the one-way valve group 8 will not turn when installed or working in the water supply pipe 6, avoiding the one-way valve group 8 from shifting due to the inability of its claws to cooperate well with the pipe three 4 due to turning, thereby avoiding the situation where the one-way conduction function fails due to displacement.

[0042] When the one-way valve group 8 is working, by setting a right-angle channel 10 on the inner bottom of the pipe three 4, at least two edges of the clamping portion of the one-way valve group 8 can cooperate with the right-angle channel 10, which is conducive to the effective clamping cooperation of the one-way valve group 8 in the water supply pipe 6, and avoids the situation where the clamping is unstable and causes it to loosen during use.

[0059] A valve cylinder 804 is also provided at the inner top of the upper valve frame 802, and an active cavity 810 is provided at the center of the upper valve frame 802. The inner wall of the valve cylinder 804 is connected to the active cavity 810 and allows the valve stem 805 to reciprocate and / or fluid to pass through; a spring 806 is sleeved on the outer wall of the valve cylinder 804; one end of the spring 806 is pressed against the inner top of the valve frame, and the other end is embedded in the spring groove 812 of the valve plug 821, and the valve stem 805 is located in the spring groove 812 of the valve plug 821.

[0060] Preferably, a notch 818 - 1 is provided on the lower surface of the valve plug 821 , and the notch 818 - 1 is concentric with the spring groove 812 , the valve stem 805 , and the valve plug 821 ; a sealing groove 2 814 is provided on the side wall of the valve plug 821 , and a rubber ring 2 815 is provided in the sealing groove 2 814 ; the valve plug 821 and the plug 817 cooperate with each other through the rubber ring 2 815 .

[0061] Preferably, an open mating groove 2 818 is provided above the plug 817, the mating groove 2 818 and the valve plug 821 cooperate with each other, and the inner wall of the opening of the mating groove 2 818 is provided with a chamfer, and the chamfer and the mating groove 2 818 are both used to cooperate with the rubber ring 2 815.

[0064] Further preferably, the elastic adjustment groove 809 is used to cooperate with the claw 803 to clamp the upper valve frame 802 to the valve chamber 16 and the inner wall of the second channel 11, thereby providing a certain degree of elasticity and preventing a clearance fit that would result in an excessive range of motion of the one-way valve assembly. Crossbeams 801 are uniformly distributed axially outwardly of the upper valve frame 802, and the crossbeams 801 are respectively connected to connecting rods 811.

[0065] In this embodiment, the one-way valve group 8 has two states when working.

[0066] When the state one is water replenishment, the water replenishment pipe 6 is opened, and when water is injected into the water replenishment pipe 6, the water flows from the pipe four 5 to the main pipe 1, and then is diverted and used through the main pipe 1. There is water in the water replenishment pipe 6, and the water pressure will rush upward and rush toward the pipe four 5 on the side wall; when rushing upward, the one-way valve group 8 will be pushed upward by the water pressure, thereby realizing the connection between the pipe three 4 and the water replenishment pipe 6, thereby achieving the purpose of water replenishment.

[0067] State 2 is no water replenishment, such as Figure 2 、 4 7-9 shows the one-way valve assembly in a compressed state, i.e., in a non-water supply state. When water is not supplied, no water pressure will appear in the pipe, i.e., no upward water pressure will appear in the water supply pipe 6. The second rubber ring 815 fits the annular wall 819, and keeps the first channel 9 and the second channel 11 disconnected.

[0068] When water replenishment is needed, after water is passed through the water replenishment pipe 6, the valve core in the one-way valve group 8 will be pushed upward under the action of water pressure, thereby achieving the purpose of one-way conduction; specifically, channel three 12 in the water replenishment pipe 6 will divert water to pipe four 5 and channel two 11 of the water replenishment pipe 6. Under the action of water pressure impact, the plug 817, valve plug 821, and valve stem 805 will move upward with the water pressure, which will cause the valve stem 805 to separate from the annular wall 819 with the rubber ring three 815, thereby opening the valve core, thereby achieving the connection between channel one 9 and channel two 11, and then achieving the purpose of water replenishment.

[0069] The one-way valve group 8 in the present invention is opened when water is replenished and closed when water is not replenished, thereby achieving the purpose of one-way conduction and interception. The guide column 14 proposed in the present invention is used to limit the steering of the one-way valve group. At the same time, the bottom surface of the right-angle channel 10 is flat, which can better abut the claw 803 of the one-way valve group 8, thereby achieving the purpose of effective and safe operation of the entire water inlet valve group.

[0070] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
