Description

Technical Field

[0001] This utility model relates to the field of water stop valve products, and in particular to the movable rod structure of water stop valves. Background Technology

[0002] The inventors of this case have developed a water stop valve that can be installed on a water pipe joint without the need for Teflon tape installation and disassembly of the outlet valve, and without the need to switch the main water valve. It includes a valve body and an axial push mechanism within the valve body to achieve the functions of self-connection when the outlet valve is installed and self-resetting when the outlet valve is removed, which brings great convenience.

[0047] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0048] The main improvement of this utility model lies in the movable rod of the water-stop valve. Therefore, other structures of the water-stop valve are not described in this embodiment. For the installation principle of the water-stop valve without Teflon tape and without shutting off the main water valve, please refer to the disclosed technology. The principle and other structures of the water-stop valve are not described in detail here. This embodiment discloses an explosion-proof water-stop section combination structure of the movable water-stop rod, which is a part of the structure of the movable water-stop rod of the water-stop valve. As shown in the figure, the movable water-stop rod 1 is inserted into the outer shell 101 of the water-stop valve 10 during use. Its structure includes a movable water-stop rod 1 with an internal axially formed water flow channel 2. One end of the water flow channel 2 is the inlet end 21 and the other end is the outlet end 22. The movable water-stop rod 1 is provided with an explosion-proof water-stop section 11. The water flow channel 2 corresponding to the explosion-proof water-stop section 11 forms an installation cavity 23 for the installation of the explosion-proof water-stop component 6. This embodiment discloses the specific structural settings of various explosion-proof water-stop section combination structures of the movable water-stop rod of this utility model. The following describes them in detail with reference to the accompanying drawings.

[0049] In this utility model, the structure of the inner mounting cavity 23 of the water-stop movable rod for installing the explosion-proof water-stop component 6 can be an integrally formed structure on the water-stop movable rod 1, such as by metal casting or integral injection molding. However, the aforementioned methods have problems such as difficulty in structural forming and low production efficiency. The structure disclosed in this embodiment is as follows: Figures 1-10 As shown, the structure is designed to reduce production difficulty, facilitate manufacturing and assembly, and provide good structural stability and the desired effect. As shown in the figure, the explosion-proof water-stop section 11 of the movable water-stop rod 1 includes an outer cylinder section 3, an inner baffle 4 located within the water flow channel 2 of the outer cylinder section 3 facing the water inlet end 21, and an outer baffle 5 located within the water flow channel 2 of the outer cylinder section 3 facing the water outlet end 22. The inner baffle 4 is configured to block the explosion-proof water-stop component 6 located within the mounting cavity 23 without affecting the flow of water through the water flow channel 2. The outer baffle 5 has a through explosion-proof water-stop hole 51 communicating with the water flow channel 2. The explosion-proof water-stop hole 51 is configured to be blocked by the explosion-proof water-stop component 6 located within the mounting cavity 23, thereby blocking the water flow channel 2. The main improvement of this utility model lies in how the finished combination structure of the water-stopping movable rod 1, outer cylinder section 3, inner baffle 4, outer baffle 5, and explosion-proof water-stopping component 6 is set. It is mainly divided into two categories: either the outer cylinder section is an integrally formed structure extending from the end of the water-stopping movable rod towards the water outlet, or the outer cylinder section is an independent component fixedly connected to the water-stopping movable rod via a connecting structure.

[0065] like Figure 6 As shown, the water-stopping movable rod 1 is provided with a connecting section 12, and the outer cylinder section 3 is an independent component that is fixedly connected to the connecting section 12 through a connecting structure (the connecting section 12 is provided with external threads and the outer cylinder section 3 is provided with internal threads) and a leak-proof sealing structure is provided between it and the connecting section 12; the inner baffle 4 is formed at the end of the connecting section 12; and the outer end 5 is integrally formed on the outer cylinder section 3.

[0068] In addition, the explosion-proof water-stopping component 6 disclosed in this utility model includes an elastic component 61 and a movable component 62. One end of the elastic component 61 abuts against the outer stop portion 5, and the other end abuts against the movable component 62. The elastic component 61 elastically pushes the movable component 62 against the inner stop portion 4. The movable component 62 is provided with a sealing portion 621 that can seal the explosion-proof water-stopping hole 51. The specific structure is shown in the figure. The elastic element 61 is a conical spring, with its larger diameter end abutting against the edge of the explosion-proof water-stop hole 51. The sealing part 621 is formed by the movable element 62 protruding towards the side of the explosion-proof water-stop hole 51. The smaller diameter end of the spring is sleeved on the sealing part 621. The sealing part 621 has a sealing guide structure (as shown in the figure, a sloping guide structure). The elastic coefficient of the elastic element 61 is selected to be within the range of water pressure where abnormal water flow changes occur in the normal water flow channel (such as water flow in the case of a burst hose or faucet). In this case, when the water flow occurs within this pressure range, the water flow will push the movable element 62 to compress the spring and move towards the outer stop 5, causing the sealing part 621 to block the explosion-proof water-stop hole 51, thereby achieving the effect of explosion-proof water-stopping. After the explosion-proof water-stopping is achieved and the abnormal water pressure is resolved, the movable element 62 will automatically reset under the tension of the spring after the abnormal water pressure disappears, and the normal water flow can be restored.

[0069] Furthermore, the inner baffle 4 disclosed in the above structure may be omitted depending on the design. For example, by fixing one end of the elastic element to the outer baffle and the other end to the movable element, the movable element 62 can be directly connected to the outer baffle 5 through the elastic element 61.

Alternatively, the outer cylinder section is an independent component that is fixedly connected to the water-stopping movable rod as a whole through a connecting structure. In the case where the outer cylinder section is an independent component, the outer baffle is also an independent component assembled into a fixed whole through a connecting structure. A leak-proof sealing structure is provided between the outer cylinder section and the water-stopping movable rod, and between the outer baffle and the outer cylinder section.
