Description

Technical Field

[0001] The utility model belongs to the technical field of controller valve bodies, and more specifically, relates to a controller valve body with good sealing and isolation effects. Background Art

[0002] Control valve, also known as regulating valve, is a final control element in the field of industrial automation process control that receives the control signal output by the regulating control unit and uses power operation to change process parameters such as medium flow, pressure, temperature, and liquid level. It is divided into three types: pneumatic regulating valve, electric regulating valve, and hydraulic regulating valve.

[0003] Based on the above, current control valves usually need to use sealing rings to seal the connection when connected to external pipelines to prevent leakage of liquids and gases. However, the sealing rings are made of rubber and are prone to dryness and hardening after long-term use, which leads to insufficient fit between the connection between the control valve and the external pipeline, thereby affecting the sealing isolation. Utility Model Content

[0004] In order to solve the above technical problems, the embodiment of the present disclosure relates to a controller valve body with good sealing and isolation effects, so as to solve the problem that the material receiving device cannot buffer the impact force of the falling material. Through the setting of the sealing structure, the fixed sleeve can be exerted with the help of external clamps, so that the sealing ring inside the fixed sleeve is tightly fitted with the connection between the control valve and the external pipeline, avoiding the sealing ring from not fitting well after drying and hardening, resulting in poor sealing of the connection between the control valve and the external pipeline, and thus effectively preventing the leakage of liquid and gas, and improving the sealing and isolation of the control valve. Through the setting of the anti-blocking structure, impurities in the conveying medium can be effectively filtered to prevent impurities from rusting the valve core and causing damage to the valve body, thereby increasing the service life of the valve body.

A rotating screw ring 2033 is provided on the outside of the connecting outer screw ring 203, and the rotating screw ring 2033 is an internal thread structure. The rotating screw ring 2033 is rotatably engaged with the connecting outer screw ring 203, and the end of the controller valve body 1 is provided with a sealing ring. The middle of the ring 202, and the fastening clamp 2032 is a three-claw structure. By inserting one end of the external connecting pipe into the inside of the fixed sleeve 201, one end of the connecting pipe is fitted with one end of the controller valve body 1, so that the sealing ring 202 is installed in the connecting gap between the two, and then the rotating screw ring 2033 is rotated to engage with the connecting outer screw ring 203, and then move on the outside of the connecting outer screw ring 203, thereby applying force to the fastening clamp 2032, so that the fastening clamp 2032 applies force to the fixed sleeve 201 after being subjected to force, and then the sealing ring 202 inside the fixed sleeve 201 is tightly fitted with the two, avoiding the sealing ring 202 not fitting well after it is dry and hardened, resulting in poor sealing at the connection between the control valve and the external pipeline.

[0041] Example 2: Based on Example 1, Figure 5 and Figure 6As shown, one side of the controller valve body 1 is provided with an anti-blocking structure 3, the anti-blocking structure 3 includes an installation arc groove 301, a fixed protrusion 3011, a fixed hinge 3012 and a hinge shaft column 3013, a installation arc groove 301 is opened on the top of one side of the controller valve body 1, one end of the installation arc groove 301 is fixedly connected to the controller valve body 1, the top of the fixed protrusion 3011 is fixedly installed with a fixed hinge 3012, and a hinge shaft column 3013 is installed on the fixed hinge 3012, and an articulation arc plate 302 is sealed and installed in the installation arc groove 301, one end of the articulation arc plate 302 is fixedly connected to the articulation arc block 3021, the articulation arc block 3021 is hinged to the fixed hinge 3012 through the articulation shaft column 3013, and the other end of the articulation arc plate 302 is fixedly connected to the locking protrusion 3022, and the locking protrusion 3022 is provided with a first through-hole 3023. 1. A connecting convex plate 303 is fixedly connected to the controller valve body 1 at the other end of 1. A second through-hole 3031 is opened on the connecting convex plate 303. The diameter of the second through-hole 3031 is the same as that of the first through-hole 3023. Assembly bolts 304 are installed in the first through-hole 3023 and the second through-hole 3031. The bottom of the assembly bolt 304 is engaged with a fastening nut 3041. A clamping ring groove 305 is opened on the inner side of the hinged arc plate 302 and the controller valve body 1. A filter screen 306 is fixedly clamped inside the clamping ring groove 305. The setting of the filter screen 306 can effectively filter impurities in the conveying medium, prevent impurities from rusting the valve core and causing damage to the valve body, and improve the service life of the valve body. By twisting the fastening nut 3041 to contact the limit on the assembly bolt 304, the assembly bolt 304 is removed, so that the hinged arc plate 302 can be opened and the filter screen 306 can be removed.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In the present invention, first, one end of the external connecting pipe is inserted into the interior of the fixed sleeve 201, so that one end of the connecting pipe fits with one end of the controller valve body 1, and the sealing ring 202 is installed in the connecting gap between the two. Then, the rotating screw ring 2033 is rotated to engage with the connecting outer screw ring 203, and then moves outside the connecting outer screw ring 203, thereby applying force to the fastening clamping claw 2032. After the fastening clamping claw 2032 is subjected to force, it applies force to the fixed sleeve 201, and then the sealing ring 202 inside the fixed sleeve 201 fits tightly with the two to avoid sealing. After the sealing ring 202 is dried and hardened, it is not tight enough, resulting in poor sealing at the connection between the control valve and the external pipeline, which can effectively prevent the leakage of liquid and gas and improve the sealing isolation of the control valve. Through the setting of the filter 306, impurities in the conveying medium can be effectively filtered to prevent impurities from rusting the valve core and causing damage to the valve body, thereby increasing the service life of the valve body. By twisting the fastening nut 3041 to contact the limit on the assembly bolt 304, the assembly bolt 304 can be removed, so that the hinged arc plate 302 can be opened and the filter 306 can be removed for replacement or cleaning.
