Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a valve with anti-clogging function. Background Technology

[0002] A valve is a device used to control the flow of fluids, liquids, or gases. It controls the flow rate, pressure, and direction of fluids by opening, closing, or regulating the flow path. The working principle of a valve usually relies on mechanical motion, enabling precise fluid management under different operating conditions. Valves are widely used in various industrial and civil systems to ensure the safe and efficient operation of fluid systems.

[0003] In the prior art, valves usually require the filter screen to be disassembled and cleaned after a period of use to prevent clogging. However, the disassembly process of the existing valve filter screen is cumbersome, time-consuming, and laborious. The disassembly of the filter screen not only requires a lot of manual intervention, but also causes inconvenience to workers during cleaning and maintenance. Therefore, a valve with anti-clogging function is proposed to solve the above problems. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a valve with anti-clogging function, which has the advantages of quick disassembly, reduced labor intensity and improved maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides an anti-clogging valve, comprising a valve body and a water supply pipe;

[0006] The valve body is provided with mounting pipes at both ends, and a limit locking assembly is externally fitted at the connection between the mounting pipe and the water supply pipe.

[0007] The limiting engagement assembly includes a mounting cylinder. A positioning ring with a through hole is fitted on one side of the inner wall of the mounting cylinder. Four locking leaves are arranged around one side of the positioning ring. An arc-shaped locking block is fitted at one end of each of the four locking leaves. A collar is fitted at one end of the mounting cylinder. An inner ring is fitted inside the collar. The inner wall of the inner ring is threaded and a threaded rod is connected to it through the thread. The threaded rod has a through hole and an arc-shaped groove is provided on the inner wall of one end of the threaded rod.

[0008] As a further improvement of this utility model, the inner wall of the mounting tube is provided with a slot and a filter screen is assembled through the slot, and a mounting ring is provided on one side of the filter screen.

[0009] As a further improvement of this utility model, the inner wall of the mounting cylinder is provided with four limiting blocks in a circumferential manner, and the outer side of the positioning ring is provided with four grooves in a circumferential manner, with the four limiting blocks respectively engaging in the four grooves.

[0010] As a further improvement of this utility model, the threaded rod is provided with anti-slip texture on the outside.

[0011] As a further improvement of this utility model, the connection points between the four card leaves and the positioning ring are all detachable.

[0012] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0013] This utility model features an anti-clogging valve. Through the interlocking of components within a limit-locking assembly, rotating the threaded rod releases its contact and compression with the four arc-shaped locking blocks. This allows the four locking leaves to release their restriction on the connection between the installation pipe and the water supply pipe, enabling rapid disassembly of the valve body and removal of the filter screen for cleaning. This prevents clogging caused by prolonged uncleaning. Traditional filter screen disassembly is not only time-consuming but also requires tools to disassemble the valve body, increasing manual labor intensity. This device, through the design of the limit-locking assembly, allows for rapid unlocking and installation of the valve body, enabling quick maintenance of the filter screen. It greatly reduces reliance on specialized tools and multi-step operations, lowering the workload of operators. Furthermore, this device allows operators to complete filter screen disassembly, installation, and cleaning in a short time, effectively shortening maintenance time and improving overall operating efficiency. It is particularly suitable for applications requiring frequent maintenance. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Depend on Figure 1-3 A valve with anti-clogging function is provided, comprising a valve body 1 and a water supply pipe 2;

[0021] Both ends of the valve body 1 are provided with mounting pipes 11, and the connection between the mounting pipe 11 and the water supply pipe 2 is externally equipped with a limit locking assembly 3;

[0022] The limiting engagement assembly 3 includes a mounting cylinder 30. A positioning ring 31 is mounted on one side of the inner wall of the mounting cylinder 30, and the positioning ring 31 has a through hole. Four locking leaves 32 are arranged around one side of the positioning ring 31. An arc-shaped locking block 33 is mounted on one end of each of the four locking leaves 32. A collar 34 is mounted on one end of the mounting cylinder 30. An inner ring 35 is mounted inside the collar 34. The inner wall of the inner ring 35 is threaded and a threaded rod 36 is connected to it by the thread. The threaded rod 36 has a through hole and an arc-shaped groove 361 is provided on the inner wall of one end of the threaded rod 36.

[0023] The inner wall of the mounting tube 11 is provided with a slot and a filter screen 12 is assembled through the slot. A mounting ring 13 is provided on one side of the filter screen 12.

[0024] In this embodiment, through the mutual cooperation between the components within the limiting engagement assembly 3, the threaded rod 36 is rotated to release its contact and compression with the four arc-shaped locking blocks 33, thereby releasing the four locking leaves 32 from limiting the connection between the installation pipe 11 and the water supply pipe 2. Subsequently, the valve body 1 can be quickly disassembled, and the filter screen 12 can be pulled out for cleaning to prevent blockage caused by prolonged uncleaning. Traditional filter screen 12 disassembly is not only time-consuming but also requires tools to disassemble the valve body, increasing the intensity of manual operation. This device, through the design of the limiting engagement assembly 3, can achieve quick unlocking and installation of the valve body 1, thereby enabling rapid maintenance of the filter screen 12. It greatly reduces the reliance on professional tools and multi-step operations, reducing the labor burden of operators. At the same time, this device allows operators to complete the disassembly, installation, and cleaning of the filter screen 12 in a short time, effectively shortening maintenance time and improving overall operating efficiency. It is particularly suitable for application scenarios that require frequent maintenance.

[0025] Specifically, refer to Figure 1-2The inner wall of the mounting cylinder 30 is provided with four limiting blocks 301, and the outer side of the positioning ring 31 is provided with four grooves, and the four limiting blocks 301 are respectively engaged in the four grooves.

[0026] In this embodiment, the positioning ring 31 is engaged and installed in the mounting cylinder 30 by four limiting blocks 301, so that when the card leaf 32 and the positioning ring 31 need to be disassembled and maintained, they can be disassembled quickly, reducing the workload of maintenance personnel.

[0027] Specifically, refer to Figure 1-2 The threaded rod 36 has anti-slip texture on the outside.

[0028] In this embodiment, by providing anti-slip texture on the outside of the threaded rod 36, the friction can be increased, making it more convenient for the user to rotate the threaded rod 36.

[0029] Specifically, refer to Figure 2 The four card plates 32 and the positioning ring 31 are all detachable.

[0030] In this embodiment, the connection points between the four card blades 32 and the positioning ring 31 are all detachable, making it more convenient to disassemble and replace the worn arc-shaped card block 33 and card blades 32 in the future.

[0031] This utility model features an anti-clogging valve:

[0032] In actual use, when the filter screen 12 needs to be disassembled for maintenance and cleaning, the threaded rod 36 is rotated to move it to one side and away from the four arc-shaped locking blocks 33, thereby canceling its contact with the four arc-shaped locking blocks 33. This causes the four locking leaves 32 to release their restriction on the installation pipe 11 and the water supply pipe 2. Then, the valve body 1 can be disassembled. By using an external tool to hook the installation ring 13 on one side of the filter screen 12, the filter screen 12 at one end of the installation pipe 11 can be pulled out to one side. After cleaning and maintenance, the filter screen 12 is pushed back into the installation pipe 11. The installation pipes 11 at both ends of the valve body 1 are aligned with the two sets of limiting locking components 3. The threaded rod 36 is rotated in the opposite direction to move it towards the four arc-shaped locking blocks 33, thereby squeezing the four arc-shaped locking blocks 33 and causing the four locking leaves 32 to squeeze and connect the installation pipe 11 and the water supply pipe 2, thus completing the installation of the valve body 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
