Description

Technical Field

[0001] The utility model relates to the technical field of control valves, in particular to a control valve that is convenient for connection. Background Art

[0002] The control valve is composed of two main assemblies: the valve body assembly and the actuator assembly (or actuator system), which are divided into four major series: single-seat series control valves, double-seat series control valves, sleeve series control valves and self-operated series control valves. The control valve should be easy to connect.

[0003] For example, a DHT multi-stage step-down high-pressure differential control valve with an easy-to-connect design, with a publication number of CN215110795U, includes a device body. The utility model provides a limit mechanism and utilizes the inertia of a fixed spring so that a limit rod can be inserted into the interior of a splicing block, so that a connecting water pipe can be installed on one side of a first connecting block, making it convenient for workers to connect the connecting water pipe, saving the physical strength of the workers and increasing the practicality of the device.

[0004] The DHT multi-stage step-down high-pressure differential control valve which is easy to connect is a valve body that is connected to a water pipe and has a limit rod inserted into the interior of the splicing block through a fixed spring, and then cooperates with an adsorption magnet to achieve the connection between the valve body and the connecting water pipe. However, with this connection method, since the spring has a certain elastic force, when the valve body is subjected to external force and the vibration of the fluid flowing through the pipeline, the spring will undergo elastic deformation, causing the limit rod to loosen, thereby reducing the firmness of the connection. In addition, with use, the adsorption magnet will also adsorb iron filings and the like in the surrounding impurities due to its own magnetic effect, thereby reducing the magnetic attraction of the adsorption magnet to the splicing block. Therefore, the actual use effect is not good. In view of this, it is very necessary to design a control valve that is easy to connect to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a control valve that is easy to connect, which solves the problems of the prior DHT multi-stage step-down high-pressure differential control valve that is easy to connect. Since the spring has a certain elastic force, when the valve body is subjected to external force and the vibration of the fluid flowing through the pipeline, the spring will undergo elastic deformation, causing the limit rod to loosen, thereby reducing the firmness of the connection. As the valve is used, the adsorption magnet will be affected by its own magnetic force and will also adsorb iron filings and the like in the surrounding impurities, thereby reducing the problem of the magnetic attraction of the adsorption magnet on the splicing block.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a control valve that is easy to connect, including a control valve body and a valve seat, a valve seat is fixedly connected to the bottom of the control valve body, a mounting plate is fixedly connected to the left and right outer walls of the valve seat, a first connecting plate that fits the valve seat is provided on the outer side of the mounting plate, a connecting pipe is fixedly connected to the inside of the first connecting plate, a fixing mechanism is installed on the left and right outer walls of the valve seat, and a connecting mechanism is installed on the inner side of the mounting plate.

[0007] Preferably, the fixing mechanism includes a second connecting plate fixedly connected to the left and right outer walls of the valve seat, a pair of through holes of the second connecting plate and the first connecting plate are gap-fitted with screws, one end of the left and right screws is fixedly connected to a baffle fitted with the outer wall of the first connecting plate, and the outer wall of the other end of the screw is threadedly connected to a sleeve, and the middle outer wall of the sleeve is fixedly connected to the interior of the mounting plate.

[0008] Preferably, sealing rings are sleeved on the left and right outer walls of the valve seat, and the outer walls at both ends of the sealing rings are respectively fitted with the outer walls of the first connecting disk and the second connecting disk.

[0009] Preferably, the connection mechanism comprises a pair of transverse plates fixedly connected to the inner outer walls of a pair of mounting plates, the interior of the transverse plates is rotatably connected to a vertical rod, and the two ends of the vertical rod are respectively fixedly connected to a first bevel gear and a rotating head.

[0010] Preferably, the outer wall of the first bevel gear is meshingly connected with a second bevel gear fixed to the sleeve.

[0011] Beneficial Effects

[0012] The utility model provides a control valve that is easy to connect and has the following beneficial effects:

[0013] The sealing ring can be sleeved on the valve seat, and then the first connecting plate is driven to move to the valve seat through the connecting pipe, and then the screw is driven to move through the baffle, so that the screw passes through the through holes of the first connecting plate and the second connecting plate and enters the sleeve, and at the same time, the inner wall of the baffle is fitted with the outer wall of the first connecting plate, and then the rotary head is rotated, and the vertical rod is driven to rotate through the rotary head, so that the vertical rod drives the first bevel gear to rotate, so that the first bevel gear can drive the sleeve to rotate through the second bevel gear, so that the sleeve can drive the screw to move, so that the screw drives the first connecting plate to move through the baffle, so that the first connecting plate squeezes the sealing ring until the first connecting plate is tightly fitted with the valve seat, thereby completing the connection and fixation of the valve seat and the connecting pipe. In this way, even if the control valve body is subjected to external force and the vibration of the fluid flowing through the connecting pipe, the firmness of the connection is not easy to reduce, and the overall connection is also convenient, so the actual use effect is better.
