Description

Technical Field

[0001] The utility model relates to the field of throttling devices, in particular to a throttling device for a valve body. Background Art

[0002] A throttle valve is a valve that controls the fluid flow by changing the throttle section or throttle length. Combining a throttle valve and a check valve in parallel can form a one-way throttle valve. Throttle valves and one-way throttle valves are simple flow control valves. In a quantitative pump hydraulic system, when a throttle valve is combined with a relief valve, three throttle speed control systems can be formed, namely, an inlet oil circuit throttle speed control system, a return oil circuit throttle speed control system, and a bypass throttle speed control system. Throttle valves do not have a flow negative feedback function and cannot compensate for the speed instability caused by load changes. Generally, they are only used in occasions where the load change is small or the requirement for speed stability is not high. Throttle valves are applied to the regulation of various fluids.

[0003] During the process of transporting water flow, the accumulation of impurity particles in the water flow will cause the blockage of the water pipe to a certain extent. However, the replacement process of the existing filtering device is relatively cumbersome and the replacement time is long, which seriously affects the normal water use of the machine or the household, thereby reducing the production efficiency of the machine and affecting the normal life of the household. In view of this, in response to this technical problem, this application proposes a throttling device for a valve body. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a throttling device for a valve body. Through the combination of a fixing block, a pin and a through groove, the clamping block can be fixed, so as to fix the filter cartridge, avoid the water hammer effect occurring in the water pipe from causing the water pipe to shake and resulting in the loosening of the clamping block, and further cause the loosening of the filter cartridge, thereby improving the stability of the connection between the fixing block and the cylinder body, enabling the filter cartridge to work normally, and simplifying the process of replacing the filter cartridge, making the replacement of the filter cartridge more convenient and improving the efficiency of replacing the filter cartridge; by setting the filter cartridge, the water flow can be filtered, thereby improving the quality of the water flow, and by setting the sealing ring, the sealing performance of the connection between the fixing block and the cylinder body can be improved, thereby avoiding the overflow of the water flow and improving the conveying efficiency.

[0021] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-3 , an embodiment provided by the present invention: a throttling device for a valve body, including a throttle valve body 1, a connecting pipe 2 is arranged on the right side of the throttle valve body 1, and the connecting pipe 2 can connect the throttle valve body 1 with the cylinder body 3, so that water flow can flow into the cylinder body 3. The right side of the connecting pipe 2 is fixedly connected with the cylinder body 3, and the right side of the cylinder body 3 is fixedly connected with a water outlet pipe 4. The filtered water flow is discharged from the water outlet pipe 4. A plurality of fixed blocks 7 are arranged on the outer wall of the top side of the cylinder body 3, and a top cover 5 is arranged on the top side of the cylinder body 3. By rotating the top cover 5, the fixed column 9 can be rotated. The bottom side of the top cover 5 is fixedly connected with the fixed column 9, and the fixed column 9 can provide an installation position for the filter cartridge 12. A plurality of clamping blocks 10 are fixedly connected to the outer wall of the bottom side of the fixed column 9. The plurality of clamping blocks 10 can be engaged with the through groove 6, and the clamping blocks 10 are fixed by the pin 8, which can improve the stability of the filter cartridge 12 in the cylinder body 3. The bottom side of the fixed column 9 is fixedly connected with a sealing ring 11, and the sealing ring 11 can ensure the sealing performance of the connection between the fixed column 9 and the cylinder body 3, avoiding water flow overflow, thereby reducing the efficiency of conveying water flow. The bottom side of the sealing ring 11 is provided with a filter cartridge 12, and the filter cartridge 12 can filter the water flow, thereby improving the water flow quality.

[0023] Refer to Figures 2-3, wherein there are two fixing blocks 7 on the outer wall of the top side of the cylinder body 3. Sockets are provided on the right sides of the two fixing blocks 7. The size of the socket is adapted to the bolt 8. The block 10 can be fixed by inserting the bolt 8 into the socket from the top side of the fixing block 7. The bolt 8 is slidably connected in the socket. A limiting plate 13 is fixedly connected to the top side of the bolt 8, and the limiting plate 13 can limit the bolt 8. The sizes of the multiple blocks 10 are all adapted to the multiple through slots 6, and the multiple blocks 10 are all slidably connected to the multiple through slots 6. Multiple through slots 6 are provided on the outer wall of the top side of the cylinder body 3. The through slots 6 are integrally in an inverted "L" shape, and an anti-slip pad is arranged in the through slots 6. The anti-slip pad can increase the friction between the block 10 and the through slot 6, thereby increasing the difficulty of moving the block 10. The multiple fixing blocks 7 are all arranged at both ends of the bottom side of the multiple through slots 6. The throttle valve body 1 and the connecting pipe 2 are connected by a flange. A handle is fixedly connected to the top side of the top cover 5, and the top cover 5 can be rotated by a staff member holding the handle.

[0024] Working principle: First, a staff member holds the handle on the top side of the top cover 5 and inserts the filter cartridge 12 into the cylinder body 3 from the top side of the cylinder body 3, so that the multiple blocks 10 on the outer wall of the fixing column 9 are snapped into the multiple vertically arranged through slots 6, and then rotates the top cover 5. The top cover 5 drives the fixing column 9 to rotate, and the fixing column 9 drives the multiple blocks 10 to rotate, so that the blocks 10 are snapped into the horizontally arranged through slots 6. Then, the bolt 8 is inserted into the socket on the right side of the fixing block 7, so as to fix the block 10 in the horizontally arranged through slot 6, thereby ensuring the stability of the filter cartridge 12 in the cylinder body 3. When the water flow passes through the filter cartridge 12, the impurities in the water flow will be filtered by the filter cartridge 12, thereby improving the quality of the water flow.
