Description

Technical Field

[0001] The utility model relates to the technical field of throttle valves, in particular to a high-pressure hydraulic throttle valve. Background Art

[0002] The throttle valve is an important flow control device. The structure of the throttle valve is relatively simple and easy to manufacture and maintain. In the hydraulic system of the quantitative pump, the throttle valve and the overflow valve can be combined to form the oil inlet throttling speed control system, the oil return throttling speed control system and the bypass throttling speed control system. The high-pressure hydraulic throttle valve is a mechanical device that controls the fluid flow through liquid pressure. It uses the principle of liquid dynamics to adjust the fluid flow rate and pressure by changing the channel area of ​​the valve, thereby achieving precise control of the fluid flow.

[0003] However, the existing high-pressure hydraulic throttle valve lacks a structure for pre-treating water, cannot effectively intercept and remove impurities such as suspended matter and particulate matter in the water, and cannot enhance the accuracy and stability of the connecting rod during the up and down movement, resulting in poor practicality. To this end, we propose a high-pressure hydraulic throttle valve. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides a high-pressure hydraulic throttle valve. The new high-pressure hydraulic throttle valve has a structure that pre-treats water before it enters the throttle valve body, which can effectively intercept and remove impurities such as suspended matter and particulate matter in the water, and can enhance the accuracy and stability of the connecting rod during the up and down movement, thereby improving practicality.

[0006] The No. 1 water inlet pipe is connected to the throttle valve body, the No. 2 water inlet pipe is arranged at one end of the No. 1 water inlet pipe, a filter is arranged between the No. 2 water inlet pipe and the No. 1 water inlet pipe, a through hole is opened inside the throttle valve body, a linear bearing is embedded in the through hole, and a sealing gasket is arranged between the linear bearing and the inner wall of the through hole.

[0007] By adopting the above technical solution, personnel can use the filter to pre-treat the water by detachably installing it between the No. 2 water inlet pipe and the No. 1 water inlet pipe. The filter is made of nylon filter. The filter uses its microporous structure to effectively intercept and remove impurities such as suspended matter and particulate matter in the water, thereby improving the water quality and achieving the purpose of filtering the water before it enters the throttle valve body.

[0008] The linear bearing provides a high-precision, low-friction linear motion track for the connecting rod that passes through the valve body, effectively improving the accuracy and stability of the connecting rod during its up and down movement, reducing vibration and noise caused by friction, and ensuring the accuracy and reliability of the throttle valve operation.

[0009] Specifically, the water inlet assembly also includes bolts, No. 1 nuts, No. 1 flanges and No. 2 flanges.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] To improve practicality, Figure 1-5 As shown, a high-pressure hydraulic throttle valve according to the present invention includes a throttle valve body 1 and a water inlet assembly 5. A hydraulic push rod 2 is provided on the top of the throttle valve body 1, and the output end of the hydraulic push rod 2 is connected to a connecting rod 3. The bottom of the connecting rod 3 is connected to a conical opening and closing member 4. A water inlet assembly 5 is provided on one side of the throttle valve body 1. The water inlet assembly 5 includes a No. 1 water inlet pipe 501, a No. 2 water inlet pipe 502 and a filter 503.

[0028] The No. 1 water inlet pipe 501 is connected to the throttle valve body 1, and the No. 2 water inlet pipe 502 is arranged at one end of the No. 1 water inlet pipe 501. A filter 503 is arranged between the No. 2 water inlet pipe 502 and the No. 1 water inlet pipe 501. A through hole 12 is opened inside the throttle valve body 1, and a linear bearing 14 is embedded in the inside of the through hole 12. A sealing gasket 13 is arranged between the linear bearing 14 and the inner wall of the through hole 12.

[0029] During use, the filter 503 is detachably installed between the No. 2 water inlet pipe 502 and the No. 1 water inlet pipe 501, and the filter 503 can be used to pre-treat the water. The filter 503 is made of nylon filter. The filter 503 uses its microporous structure to effectively intercept and remove impurities such as suspended matter and particulate matter in the water, thereby improving the water quality and achieving the purpose of filtering the water before it enters the throttle valve body 1.

[0030] The linear bearing 14 provides a high-precision, low-friction linear motion track for the connecting rod 3 that passes through the valve body, effectively improving the accuracy and stability of the connecting rod 3 during the up and down movement, reducing the vibration and noise caused by friction, and ensuring the accuracy and reliability of the throttle valve operation.

[0031] For example, Figure 2 As shown, the water inlet assembly 5 also includes a bolt 504, a No. 1 nut 505, a No. 1 flange 506 and a No. 2 flange 507. The No. 1 flange 506 and the No. 2 flange 507 are respectively connected to the ends of the No. 1 water inlet pipe 501 and the No. 2 water inlet pipe 502. The bolt 504 is arranged on the outside of the No. 2 water inlet pipe 502, and the No. 1 nut 505 is arranged on the outside of the No. 1 water inlet pipe 501.

[0032] When in use, the No. 1 flange 506 and the No. 2 flange 507 on the No. 1 water inlet pipe 501 and the No. 2 water inlet pipe 502 can detachably clamp the filter screen 503 .

[0033] For example, Figure 2 As shown, the water inlet assembly 5 further includes a bolt hole 508 , and the first flange 506 , the filter screen 503 and the second flange 507 are all provided with a bolt hole 508 therein.

[0034] When in use, the bolt holes 508 facilitate the bolts 504 to pass through the No. 1 flange 506 , the filter screen 503 and the No. 2 flange 507 .

[0035] For example, Figure 1 、 Figure 4 As shown, a reinforcement plate 8 is provided on the top of the hydraulic push rod 2, reinforcement rods 9 are connected to the four sides of the top of the throttle valve body 1, and No. 2 nuts 10 are provided on the four sides of the outer side of the reinforcement plate 8.

[0036] When in use, the hydraulic push rod 2 can be reinforced by the reinforcement rod 9 and the No. 2 nut 10 to improve the stability of the hydraulic push rod 2.

[0037] For example, Figure 1 As shown, a water outlet pipe 6 is provided on the other side of the throttle valve body 1 , and a valve seat 7 is provided at the bottom of the throttle valve body 1 .

[0038] When in use, the water outlet pipe 6 facilitates the discharge of water from the throttle valve body 1 , and the valve seat 7 can support the throttle valve body 1 .

[0039] For example, Figure 4 As shown, a valve cavity 11 is defined inside the throttle valve body 1 .

[0040] When in use, the valve cavity 11 facilitates the flow of the medium and the movement of the conical opening and closing member 4.

[0041] When the utility model is in use, the personnel place the filter screen 503 between the No. 2 water inlet pipe 502 and the No. 1 water inlet pipe 501, and the filter screen 503 can be detachably set between the No. 2 water inlet pipe 502 and the No. 1 water inlet pipe 501 by means of the bolt 504 and the No. 1 nut 505, so that the filter screen 503 can be used to pre-treat the water. The filter screen 503 is made of nylon filter screen. The filter screen 503 uses its microporous structure to effectively intercept and remove impurities such as suspended matter and particulate matter in the water, thereby improving the water quality.

[0042] Furthermore, the personnel pass the top of the reinforcement rod 9 through the reinforcement plate 8, sleeve the No. 2 nut 10 on the outer periphery of the top of the reinforcement rod 9, and tighten the No. 2 nut 10 to reinforce the hydraulic push rod 2 to improve the stability of the hydraulic push rod 2 during operation;

[0043] Furthermore, the through hole 12 inside the throttle valve body 1 facilitates the connection rod 3 to pass through the throttle valve body 1 and connect with the conical opening and closing member 4. The linear bearing 14 provides a high-precision, low-friction linear motion track for the connection rod 3 passing through the valve body, effectively improving the accuracy and stability of the connection rod 3 during the up and down movement, and reducing the vibration and noise caused by friction.

[0044] Furthermore, the sealing gasket 13 cooperates with the linear bearing and the rod to form a multi-level sealing structure. The linear bearing 14 itself has a good sealing design and can effectively prevent medium leakage.
