Description

Technical Field

[0001] This utility model relates to the field of valve switching technology, specifically to an angle valve that is easy to install. Background Technology

[0002] Currently, with the increasing variety of water-using sanitary ware products, the requirements for water quality are also becoming more stringent in order to enhance the enjoyment and user experience of daily life. For example, in some areas, the water contains a lot of impurities such as sediment and rust, which can cause blockages or blockages in water-using sanitary ware, leading to poor water flow or even leaks. In other areas, the water contains high levels of calcium and magnesium ions, which can form limescale over time, affecting the normal function and aesthetic experience of sanitary ware.

[0003] Chinese utility model patent CN 219975351U discloses a filter angle valve, including a valve body with an outlet on its side and an inlet at its lower end. The valve body contains an axially movable valve stem with a valve plate that, when moved upwards, blocks the communication channel between the inlet and outlet. An axially movable knob assembly, sealed to the valve body, is located at the upper opening of the valve body. The knob assembly includes a switch cap, a bracket integrally formed with the lower end of the switch cap, and a sleeve. The valve stem is inserted into the sleeve for fixation. A cylindrical filter screen is fitted onto the bracket. Because the valve stem in this filter valve blocks the inlet by water pressure when the knob is turned off, but there is no limiting structure between the valve stem and the valve body, this angle valve can only be installed on horizontal pipes. If installed in a vertical pipe, the entire valve stem will fall into the pipe, rendering the angle valve unusable. This limits the application range of this angle valve and causes inconvenience during installation. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an angle valve with a simple structure and convenient installation.

[0029] Reference Figure 1 , Figure 2 and Figure 3As shown, an easy-to-install angle valve includes a valve body 1, with an outlet 10 on the side and an inlet 11 at the lower end. The valve body 1 contains an axially movable valve stem 2. The valve stem 2 has a valve plate 3 that, when moved upwards, blocks the communication channel between the inlet 11 and the outlet 10. An axially movable knob assembly 4, sealed to the valve body 1, is provided on the upper opening 12 of the valve body 1. The knob assembly 4 includes a switch cap 5, and the lower end of the switch cap 5 has an integrally formed... A bracket 6 is fitted with a cylindrical filter screen. The valve body 1 has an integrally formed limiting seat 8 on its inner wall. The limiting seat 8 has a water inlet hole 80 in its center. The valve stem 2 moves downwards or upwards, causing the valve plate 3 to move away from or block the water inlet hole 80, thereby controlling the angle valve's water flow or closure. The valve stem 2 has two limiting hooks 20, symmetrically distributed on the left and right sides of the valve stem 2. The distance between the outer sides of the two limiting hooks 20 is greater than the diameter of the water inlet hole 80. Because of the added valve stem on both sides, the angle valve can be installed in vertical or horizontal square pipes, thus not being restricted by the pipe's direction. When the pipe is vertical, the valve stem moves downwards during installation, causing the limiting seat to block the limiting hooks 20, preventing the valve stem from falling into the pipe and causing installation inconvenience.

[0030] In this embodiment, in order to increase the water tightness between the limiting seat 8 and the valve plate 3, a first sealing ring 9 is provided on the outer wall of the valve plate 3, which can seal with the limiting seat 8. A first sealing groove 30 is provided on the outer wall of the valve plate 3 in the circumferential direction, and the first sealing ring 9 is embedded in the first sealing groove 30.

[0031] In this embodiment, the opening 12 is provided with an internal thread 13, and the switch cap 5 is screwed onto the opening 12.

[0032] In this embodiment, in order to increase the water tightness between the switch cap 5 and the valve body 1, a second sealing ring 7 is provided between the switch cap 5 and the opening 12, and a second sealing groove 50 is provided on the switch cap 5, with the second sealing ring 7 embedded in the second sealing groove 50.

[0033] When this utility model is in use, when the valve is opened, the switch cap 5 is turned to move it downwards. The switch cap 5 causes the valve stem 2 to move downwards. The downward movement of the valve stem 2 causes the valve plate 3 to leave the water inlet hole 80, so that the water inlet 11 and the water outlet 10 are connected. The cylindrical filter screen can play a filtering role between the water inlet 11 and the water outlet 10.

[0034] When the valve is closed, turn the switch cap 5 to move it upward. Under the action of water pressure, the valve plate 3 and the valve stem 2 move upward at the same time. The valve plate 5 can block the inlet hole 80, so that the communication channel between the inlet 11 and the outlet 10 is closed.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
