Description

Technical Field

[0001] This utility model relates to the field of one-way throttle valve technology, and in particular to a one-way throttle valve with good anti-clogging effect. Background Technology

[0002] One-way throttle valves are commonly used flow control components, widely applied in hydraulic and pneumatic systems. Their function is to regulate and control the flow rate of fluid while allowing it to flow in one direction. However, in practical use, one-way throttle valves often face the problem of clogging. For example, in hydraulic systems, impurities and particles in the oil easily accumulate at the throttle orifice, causing it to shrink or even completely blockage, affecting the normal operation of the one-way throttle valve and consequently impacting the performance and stability of the entire system. Currently available one-way throttle valves have shortcomings in anti-clogging performance. Some rely solely on simple filters to remove impurities; however, these filters are easily clogged and difficult to clean, failing to fundamentally solve the clogging problem, reducing equipment efficiency, and increasing maintenance costs. Therefore, we propose a one-way throttle valve with superior anti-clogging performance. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a one-way throttle valve with excellent anti-clogging performance. This invention solves the problem of insufficient anti-clogging performance in existing one-way throttle valves on the market. Some one-way throttle valves rely solely on simple filters to remove impurities; however, these filters are easily clogged by impurities, making cleaning difficult and failing to fundamentally solve the clogging problem of the one-way throttle valve. This reduces equipment efficiency and increases maintenance costs.

[0004] This utility model discloses a one-way throttle valve with good anti-clogging effect, comprising a throttle valve body, a filter tube provided on the water inlet side of the throttle valve body, a limiting ring provided on the side of the throttle valve body near the filter tube, a connecting ring provided on the outside of the limiting ring, the filter tube and the connecting ring being threadedly connected, a connecting rod inserted into the middle of the side of the filter tube away from the throttle valve body, an installation rod provided at one end of the connecting rod inside the filter tube, bristles provided on the side of the installation rod away from the connecting rod, a filter screen provided inside the filter tube on the side of the bristles away from the connecting rod, a drain pipe provided below the filter tube, a sealing bolt provided below the drain pipe, and a water inlet pipe provided above the filter tube.

[0005] In the above scheme, a sealing gasket is provided between the sealing bolt and the sewage pipe.

[0006] In the above scheme, a sealing ring is provided between the filter tube and the limiting ring.

[0007] In the above scheme, the outer side of the connecting ring is provided with a first anti-slip texture.

[0008] In the above scheme, the connecting rod is fixedly connected to the rotating block on the side away from the filter tube, and the rotating block is provided with a second anti-slip texture on the outer side.

[0009] In the above scheme, the end of the sealing bolt is provided with an internal hexagon countersunk head.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a one-way throttle valve with good anti-clogging effect. It connects to the filter tube via a connecting ring, allowing the filter tube and the throttle valve body to communicate with each other. When the rotating block rotates, the rotating block drives the connecting rod to rotate, which in turn drives the mounting rod to rotate. Through the transmission of the mounting rod, the brush bristles also rotate. The rotating bristles can clean solid impurities attached to the filter screen. The solid impurities cleaned by the bristles can be discharged through the drain pipe. The sealing gasket and sealing ring effectively ensure the overall sealing performance of the one-way throttle valve. This type of one-way throttle valve has a simple structure, good sealing effect, and can effectively filter solid impurities in the water flow. The filtered impurities are easy to clean, effectively improving the practicality of the one-way throttle valve. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1-3 As shown, this utility model is a one-way throttle valve with good anti-clogging effect, including a throttle valve body 1. A filter tube 2 is provided on the inlet side of the throttle valve body 1. A limiting ring 3 is provided on the side of the throttle valve body 1 near the filter tube 2. A connecting ring 4 is provided on the outer side of the limiting ring 3. The filter tube 2 is threadedly connected to the connecting ring 4. The filter tube 2 and the throttle valve body 1 can communicate with each other through the connection between the connecting ring 4 and the filter tube 2. A connecting rod 5 is inserted into the middle of the side of the filter tube 2 away from the throttle valve body 1. The connecting rod 5 is movably connected to the filter tube 2 and can rotate inside the filter tube 2. An installation rod 6 is provided at one end of the connecting rod 5 inside the filter tube 2. A brush bristle 7 is provided on the side away from the connecting rod 5. A filter screen 8 is provided inside the filter tube 2 on the side of the brush bristle 7 away from the connecting rod 5. The filter screen 8 can filter solid impurities that enter the filter tube 2. When the connecting rod 5 is rotated, the connecting rod 5 drives the mounting rod 6 to rotate. Through the transmission of the mounting rod 6, the brush bristle 7 also rotates. The rotating brush bristle 7 can clean the solid impurities attached to the filter screen 8. A drain pipe 9 is provided below the filter tube 2. The solid impurities cleaned by the brush bristle 7 can be discharged through the drain pipe 9. A sealing bolt 10 is provided below the drain pipe 9. The sealing bolt 10 can seal the drain pipe 9. A water inlet pipe 11 is provided above the filter tube 2.

[0018] A sealing gasket 12 is provided between the sealing bolt 10 and the drain pipe 9, and the sealing gasket 12 can seal the contact surface between the sealing bolt 10 and the drain pipe 9.

[0019] A sealing ring 13 is provided between the filter tube 2 and the limiting ring 3, which can seal the contact surface between the filter tube 2 and the limiting ring 3.

[0020] The outer side of the connecting ring 4 is provided with a first anti-slip texture 14. The first anti-slip texture 14 effectively increases the friction between the finger and the connecting ring 4, making it easier to connect the connecting ring 4 and the filter tube 2.

[0021] The connecting rod 5 is fixedly connected to the rotating block 15 on the side away from the filter tube 2. The rotating block 15 is provided with a second anti-slip texture 16 on the outer side. The setting of the rotating block 15 makes it easier for the operator to rotate the connecting rod 5. The second anti-slip texture 16 effectively increases the friction between the fingers and the rotating block 15.

[0022] The sealing bolt 10 has an internal hexagon countersunk head 17 at the screw head end.

[0023] Specifically, in this utility model, the filter tube 2 is connected to the connecting ring 4, allowing the filter tube 2 and the throttle valve body 1 to communicate with each other. When the rotating block 15 is rotated, the rotating block 15 drives the connecting rod 5 to rotate, and the connecting rod 5 drives the mounting rod 6 to rotate. Through the transmission of the mounting rod 6, the brush bristles 7 also rotate. The rotating brush bristles 7 can clean the solid impurities attached to the filter screen 8. The solid impurities cleaned by the brush bristles 7 can be discharged through the drain pipe 9. The sealing gasket 12 can seal the contact surface between the sealing bolt 10 and the drain pipe 9, and the sealing ring 13 can seal the contact surface between the filter tube 2 and the limiting ring 3. Through the setting of the sealing gasket 12 and the sealing ring 13, the overall sealing performance of the one-way throttle valve is effectively guaranteed.
