Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a one-way valve which has a cut-off capability when tilted. Background Art
[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, or overflow and pressure relief.
[0003] Currently, valves do not have the function of cutting off at a certain angle. Valves that need to control the angle of cutting off need to be equipped with electronic devices for control. Utility Model Content
[0004] The purpose of the utility model is to provide a one-way valve with cut-off capability when tilted, so as to solve the problems in the current market raised by the above background technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a one-way valve having a shutoff capability when tilted, comprising a housing for allowing fluid to enter and exit a designated area, the housing comprising an upper cover and a bottom cover, the upper cover and the bottom cover being connected, the upper cover comprising an upper chamber, a lower chamber, and an outlet, the bottom cover having an inlet, the lower chamber being in contact with the bottom cover, the upper and lower chambers being formed when the upper and bottom covers are closed for fixing a valve core, the valve core being movable within the upper and lower chambers;
[0006] The valve core includes a gate body, a spring and a ball. The gate body is provided with a horizontal grid, a vertical grid and a groove body. The spring and the ball are installed in the groove body. The gate body and the bottom cover are used to control the opening and closing of the inlet. The ball and the upper cover are used to control the opening and closing of the outlet. The distance between the valve core and the outlet is less than the radius of the ball.
[0007] Furthermore, the upper cover and the bottom cover are threadedly connected, and the threaded connection method is convenient for quick installation and disassembly, which is beneficial to later maintenance.
[0008] Furthermore, the bottom cover is connected to the upper cover by screws, and the screw installation method increases the firmness of the connection, further improving its sealing performance and overall compressive strength.
[0009] Furthermore, the thickness of both the longitudinal grid and the longitudinal grid is smaller than the radius of the sphere, thereby ensuring the normal flow of the fluid and preventing the sphere from flowing out.
[0010] The longitudinal and longitudinal grids are distributed at equal angles about the center line of the gate body, and adopt a design of longitudinal and longitudinal grids. There are 4 groups of longitudinal and longitudinal grids, and the equal-angle design increases their stability.
[0011] Compared with the prior art, the beneficial effect of the present invention is that the one-way valve with cut-off capability when tilted is provided with a valve core, which automatically controls the cut-off capability of the valve body after the valve body tilts at a certain angle, thereby increasing the practicality of the valve body.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-5 The utility model provides a technical solution: a one-way valve with shut-off capability when tilted, wherein an upper cover 11 and a bottom cover 12 are fixed together to form a shell 1, and the shell 1 is used to be fixed to a container and a pipeline, and an upper chamber 31 and a lower chamber 32 are formed inside the shell 1, and a valve core 2 is installed in the chamber 31 and the lower chamber 32, and the valve core 2 can move between an inlet 121 and an outlet 111 in the upper chamber 31 and the lower chamber 32 to open and close the inlet 121 and the outlet 111;
[0020] like Figure 1As shown, when the valve body tilt cut-off function is not triggered, when the external pressure at the inlet 121 reaches a predetermined value, the valve core 2 moves toward the outlet 111, and the inlet 121 is opened. At this time, the fluid can enter the lower chamber 32, and then enter the upper chamber 31 through the gap of the horizontal grid 211 on the gate body 21, and reach the outlet 111 through the gap of the longitudinal grid 212 in the upper chamber 31;
[0021] When the valve body tilt cut-off function is triggered, the force exerted on the spring 22 by the ball 23 is reduced and the spring is released. At this time, the ball 23 is affected by the change in direction of gravity and the force of the spring and moves toward the outlet 111 to close the outlet 111.
[0022] like Figure 2 The gate body 21 is shown with a transverse grid 211 and a longitudinal grid 212. The gap therebetween allows fluid to pass through while limiting the range of movement of the gate body 21 in the upper chamber 31 and the lower chamber 32. The longitudinal grid 212 matches the upper chamber 31 to ensure that the valve core 2 is stable so that it can only move between the inlet 121 and the outlet 111 in the upper chamber 31 and the lower chamber 32, ensuring the airtightness of the inlet 121 and the outlet 111. The transverse grid 211 provides space for fluid flow when the inlet 121 is open, while reserving a small space to prevent the ball from escaping from the groove 213. The distance between the valve core 2 and the outlet 111 cannot be greater than the radius of the ball.
[0023] The mass of the sphere 23 must be considered when selecting the spring 22 to ensure that when the valve body tilt cut-off function is not triggered, the spring 22 is deformed to prevent accidental closing of the inlet 121 and the outlet 111. When the valve body tilt cut-off function is triggered, the length of the spring 22 must be sufficient to enable the sphere 23 to close the outlet 111 at the outlet 111 and the gate body 21 to close at the inlet 121.
[0024] When the external pressure at the inlet 121 reaches a predetermined value, the valve core 2 will move toward the outlet 111, and the inlet 121 will be opened. Changing the overall weight of the gate body 21 can change the control of the valve body on the predetermined value of the external pressure to achieve pressure stabilization or overflow pressure relief functions.
[0025] When fluid enters the outlet 111 , the gate body 21 will close the inlet 121 , and the gate body 21 has a larger pressure-bearing area at the outlet 111 than at the inlet 121 , thus preventing backflow.
[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
