Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of check valves, and particularly relates to a highly sealed check valve for a high-pressure cleaner. Background Technique
[0002] A high-pressure cleaner is a machine that uses a power device to make a high-pressure plunger pump generate high-pressure water to wash the surface of an object. It can peel off and wash away dirt to achieve the purpose of cleaning the surface of the object. A check valve is a valve through which fluid can only flow along the inlet, and the medium at the outlet cannot flow back, commonly known as a check valve. A check valve is also called a non-return valve or a reflux valve. It is used in a hydraulic system to prevent the reverse flow of oil, or in a pneumatic system to prevent the reverse flow of compressed air.
[0003] A check valve is an essential component in the working process of a high-pressure cleaner. Most check valves adopt a spring-return structure. However, during long-term use, the valve core connected to the spring may have a certain position deviation or even tilt due to continuous water flow impact, resulting in insufficient sealing inside the check valve body and easily causing leakage. Content of the Utility Model
[0004] Aiming at the above-mentioned disadvantages of the existing technology, the utility model provides a highly sealed check valve for a high-pressure cleaner, which can effectively solve the problems of the existing technology.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a highly sealed check valve for a high-pressure cleaner, including a check valve body and a check valve seat clamped at the lower end of the check valve body, and further includes:
[0007] A check valve core, slidably clamped inside the check valve body, and the lower end surface of the check valve core is in contact with the check valve seat, and an O-ring seal is sleeved on the outer surface of the check valve seat;
[0008] A check valve spring, sleeved on the upper surface of the check valve core, and the check valve spring is in contact with the inner wall of the check valve body;
[0009] A limiting component, arranged inside the check valve body and connected to the check valve core, for limiting the position of the check valve core.
[0010] Furthermore, multiple groups of reinforcing ribs are arranged on the outer side of the check valve body, drainage outlets are arranged between the multiple groups of reinforcing ribs, and there are 4 drainage outlets.
[0011] Furthermore, a limiting member is fixed inside the inner wall of the check valve body, and the check valve body is clamped with the check valve seat through the limiting member.
[0012] Further, a reset chamber is provided at the upper end inside the one-way valve body. The cross-section of the one-way valve core is a "T" - shaped structure and extends into the reset chamber.
[0013] Further, the one-way valve spring is sleeved on the outer surface of the one-way valve core, and the one-way valve spring is located inside the reset chamber.
[0014] Further, an inclined slope is provided at the upper end inside the one-way valve seat, and the cross-section of the inclined slope is an inverted trapezoid structure. A sealing component is fixed to the lower end surface of the one-way valve core, and the sealing component is in contact with the inner wall of the inclined slope.
[0015] Further, the limiting component includes a limiting groove, a limiting slide rod and a reset spring. The limiting grooves are symmetrically opened on the left and right sides of the one-way valve body. The limiting slide rod is slidably clamped inside the limiting groove, and the other end of the limiting slide rod is fixed to the upper end surface of the one-way valve core. A reset spring is arranged inside the limiting groove, and the other end of the reset spring is in contact with the limiting slide rod.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0026] Please refer to Figures 1-4 As shown, the present invention is a highly sealed one-way valve for a high-pressure cleaner, including a one-way valve body 1 and a one-way valve seat 2 clamped to the lower end of the one-way valve body 1, and further including:
[0027] A one-way valve core 3, which is slidably clamped inside the one-way valve body 1, and the lower end surface of the one-way valve core 3 is in contact with the one-way valve seat 2. An O-ring seal 6 is sleeved on the outer surface of the one-way valve seat 2; multiple groups of reinforcing ribs are arranged on the outer side of the one-way valve body 1, and drain outlets 101 are provided between the multiple groups of reinforcing ribs, and there are 4 groups of drain outlets 101. By providing the reinforcing ribs, the one-way valve body 1 can be strengthened to prevent damage to the one-way valve body 1 and affect subsequent processing. Then, the multiple groups of drain outlets 101 provided enable water to flow normally. A limiting member 102 is fixed inside the inner wall of the one-way valve body 1, and the one-way valve body 1 is clamped to the one-way valve seat 2 through the limiting member 102. By providing the limiting member 102, the position of the one-way valve body 1 can be limited to prevent the one-way valve body 1 from shifting and shaking, thereby ensuring its subsequent processing;
[0028] The one-way valve spring 4 is sleeved on the upper surface of the one-way valve core 3 and is in contact with the inner wall of the one-way valve body 1. At the upper end inside the one-way valve body 1, a reset chamber 103 is provided. The cross-section of the one-way valve core 3 is a "T" shaped structure and extends into the reset chamber 103. The one-way valve spring 4 is sleeved on the outer surface of the one-way valve core 3 and is located inside the reset chamber 103. By providing the reset chamber 103, the position of the one-way valve core 3 can be limited, preventing the one-way valve core 3 from shifting. Furthermore, the reset chamber 103 can also limit the one-way valve spring 4, preventing the one-way valve spring 4 from shifting. At the same time, since the one-way valve spring 4 can be retracted into the reset chamber 103, it can not only protect the one-way valve spring 4 from damage but also prevent the one-way valve spring 4 and the one-way valve core 3 from shifting. At the upper end inside the one-way valve seat 2, an inclined slope 201 is provided, and the cross-section of the inclined slope 201 is an inverted trapezoid structure. A sealing component 301 is fixed to the lower end surface of the one-way valve core 3 and is in contact with the inner wall of the inclined slope 201. Through the sealing component 301 at the lower end of the one-way valve core 3, it can be in close contact with the inclined slope 201, ensuring the sealing effect of the one-way valve and preventing the one-way valve core 3 from shifting out of position.
[0029] A limiting component 5 is provided inside the one-way valve body 1 and is connected to the one-way valve core 3 for limiting the position of the one-way valve core 3. The limiting component 5 includes a limiting groove 501, a limiting slide bar 502, and a reset spring 503. The limiting grooves 501 are symmetrically opened on the left and right sides of the one-way valve body 1. The limiting slide bar 502 is slidably clamped inside the limiting groove 501, and the other end of the limiting slide bar 502 is fixed to the upper end surface of the one-way valve core 3. A reset spring 503 is provided inside the limiting groove 501, and the other end of the reset spring 503 is in contact with the limiting slide bar 502. By providing the limiting groove 501, the limiting slide bar 502 can be limited, preventing the limiting slide bar 502 from shifting and wobbling. Then, when compressed fluid enters the cavity of the one-way valve seat 2, the one-way valve core 3 can be pushed upward, allowing the fluid to be discharged from the drain outlet 101. If there is no fluid pressure in the one-way valve seat 2, under the action of the one-way valve spring 4, the one-way valve core 3 can be pushed downward, causing the sealing component 301 to contact the inclined slope 201 on the upper end surface of the one-way valve seat 2, making the one-way valve in a sealed state. The provided limiting component 5 can further limit the one-way valve core 3, ensuring the stability of the one-way valve core 3. The provided reset spring 503 can not only share the pressure of the one-way valve spring 4 but also ensure the subsequent sealing effect of the one-way valve core 3.
[0030] The above are only the preferred embodiments of the present utility model and do not limit the present utility model. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, or improvement made shall fall within the protection scope of the present utility model.
