Description

Technical Field

[0001] This utility model relates to the field of control valve technology, specifically to a flow control valve that is easy to disassemble and assemble. Background Technology

[0002] Flow control valves are valves that control the flow rate at a throttling orifice by changing the size of the liquid resistance at a certain pressure difference, thereby regulating the movement speed of the actuator. In the present technology, flow control valves are generally connected to pipelines through flanges, which are then fixed together with bolts. However, when it is necessary to disassemble or assemble the flow control valve, the bolts are prone to rust after long-term use, which makes disassembly of the flow control valve difficult and does not improve the disassembly efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a flow control valve that is easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flow control valve that is easy to disassemble and assemble, comprising a flow control valve, wherein a fixing plate is fixedly connected to both ends of the flow control valve, a threaded sleeve is provided on one side of the fixing plate, the internal thread of the threaded sleeve is connected to the thread of a connecting pipe, a first flange is fixedly connected to one end of the connecting pipe, and a second flange is fixedly connected to one end of the threaded sleeve.

[0005] Preferably, the flow control valve has fixing grooves on both sides of its outer wall, a fixing arc plate is provided in the fixing groove, a second extension plate is fixedly connected to the top and bottom of the fixing arc plate, a first extension plate is fixedly connected to the top and bottom of the fixing groove, and the first extension plate and the second extension plate are fixedly connected by fixing bolts.

[0006] Preferably, a threaded groove is provided on one side of the second flange, and a fixing plate is threadedly connected in the threaded groove.

[0007] Preferably, the other end of the connecting pipe is a corrugated pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This utility model discloses a flow control valve that is easy to assemble and disassemble. By setting a connecting pipe, the first flange of the connecting pipe is fixedly connected to the flange of the pipeline. After the flow control valve is placed in a suitable position, the threaded sleeve is stretched to the appropriate position through the connecting pipe. By rotating the threaded sleeve, the threaded groove is threaded to the fixed plate. When it is necessary to disassemble the flow control valve, the threaded sleeve is rotated in the opposite direction to unscrew it, thus facilitating the assembly and disassembly of the flow control valve.

[0010] This utility model discloses a flow control valve that is easy to install and disassemble. By setting a connecting pipe with one end being a bellows, the position of the flow control valve can be easily moved to the side of the flow control valve fixing plate without considering the position of the flow control valve, and the flow control valve can be installed on the pipeline in a relatively convenient manner.

[0011] This utility model discloses a flow control valve that is easy to assemble and disassemble. By opening a fixing groove, a fixing arc plate is set in the fixing groove, and the fixing arc plate is fixed to the flow control valve by fixing bolts. This prevents the flow control valve and connecting pipe from becoming loose after the flow control valve is installed, which would cause side leakage and affect its use. Attached Figure Description

[0018] Please see Figure 1-2 This utility model provides a technical solution: a flow control valve 1 that is easy to disassemble and assemble, including a flow control valve 1, with fixed plates 6 fixedly connected to both ends of the flow control valve 1, and a threaded sleeve 4 provided on one side of the fixed plate 6. The internal thread of the threaded sleeve 4 is connected to the thread of the connecting pipe 2. A first flange 3 is fixedly connected to one end of the connecting pipe 2, and a second flange 5 is fixedly connected to one end of the threaded sleeve 4. A threaded groove 9 is provided on one side of the second flange 5, and the fixed plate 6 is threadedly connected in the threaded groove 9, realizing the connection between the second flange 5 and the fixed plate 6. When the connecting pipe 2 is moved to a suitable position, the operator rotates the threaded sleeve 4. The rotation of the threaded sleeve 4 will cause the second flange 5 to move towards the flow control valve 1. During the movement, the fixed plate 6 will be inserted into the threaded groove 9, realizing the fixed connection between the connecting pipe 2 and the flow control valve 1. It should be noted that after the threaded sleeve 4 moves close to the end of the flow control valve 1, the threaded end of the connecting pipe 2 will be fully inserted into the threaded groove 9. Because the connection is achieved by threads, it is very convenient to disassemble and assemble.

[0019] Furthermore, the flow control valve 1 has fixing grooves 11 on both sides of its outer wall, and fixing arc plates 8 are provided in the fixing grooves 11. The top and bottom of the fixing arc plates 8 are fixedly connected to the second extension plates 10, and the top and bottom of the fixing grooves 11 are fixedly connected to the first extension plates 7. The first extension plates 7 and the second extension plates 10 are fixedly connected by fixing bolts.

[0020] Furthermore, the other end of the connecting pipe 2 is a bellows, which allows for easy adjustment of the length of the connecting pipe 2, facilitating the installation of the flow control valve 1 and the connecting pipe 2.

[0021] Working principle: First, the flange of the pipe is fixedly connected to the first flange 3 of the connecting pipe 2 by fixing bolts. Then, the flow control valve 1 is placed. Next, the connecting pipe 2 is stretched to move the second flange 5 next to the flow control valve 1. Then, the threaded sleeve 4 is rotated to insert the threaded groove 9 into the fixing plate 6, thus realizing the connection between the flow control valve 1 and the connecting pipe 2.

[0022] During the above operation, the connecting pipe 2 can be stretched again to allow the fixing plate 6 to be better inserted into the threaded groove 9. After the above operation is completed, the fixing arc plate 8 is inserted into the fixing groove 11, and the fixing guard plate 8 is fixed to the flow control valve 1 by fixing bolts to prevent the flow control valve 1 from falling off.
