[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant and wear-resistant self-operated regulating valve, comprising a regulating valve body, a connecting pipe, and an installation assembly. The connecting pipe is fixedly installed on the left side of the regulating valve body, and a flexible pipe is fixedly installed on the right side of the regulating valve body.

The installation assembly is fixedly disposed on the side surface of the first cover. The installation assembly includes an installation frame, an installation frame is fixedly installed on the side surface of the first cover, and an installation frame is fixedly installed on the side surface of the second cover. A groove is formed on the surface of the installation frame.

[0007] Preferably, the inner wall of the groove is fixedly connected with a sealing gasket layer. There are two sealing gasket layers, which are symmetrically arranged at the center of the regulating valve body. The sealing gasket layers help to increase the sealing between the first cover and the second cover.

[0008] Preferably, a positioning post is fixedly connected to the side surface of the first cover, and there are two positioning posts. A first clamping block is rotatably connected to the outer surface of the positioning post. A first fixing rod is fixedly connected to the side of the first clamping block away from the positioning post. A second clamping block is rotatably connected to the outer surface of the other positioning post. A second fixing rod is fixedly connected to the side of the second clamping block away from the positioning post. A tension spring is fixedly connected to the outer surface of the first fixing rod. The side of the tension spring away from the first fixing rod is fixedly connected to the outer surface of the second fixing rod. The tension spring facilitates the control of the distance between the first clamping block and the second clamping block to ensure that the position of the limiting block can be restricted.

[0009] Preferably, a mounting box is fixedly connected to the side surface of the second cover. The mounting box is rectangular and has a linkage groove inside, which facilitates the installation of the internal structure.

[0010] Preferably, a limiting spring is fixedly connected to the side of the linkage groove away from the second cover, and a linkage block is fixedly connected to the side of the limiting spring away from the linkage groove. The linkage block is rectangular in shape and is slidably connected to the inner wall of the linkage groove. The linkage block is in contact with the side surface of the second cover. The limiting spring facilitates the reset spring force of the linkage block support to ensure that the position of the limiting block can be restricted.

[0011] Preferably, a connecting rod is fixedly connected to the side of the linkage block near the limiting spring. The connecting rod passes through the mounting box.

The cooperation of the crossbars and the limiting blocks facilitates the fixing of the position between the first cover and the second cover.

[0012] Preferably, a pull rod is fixedly connected to the side of the crossbar away from the connecting rod. The pull rod facilitates the operator to operate the two crossbars together, further increasing the efficiency of the installation between the first and second covers.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this utility model, by setting up an installation component, when it is necessary to install the first cover and the second cover, the worker first holds the pull rod with one hand and pulls the pull rod outward. Then the pull rod drives the connecting rod to move through the crossbar. The movement of the connecting rod drives the linkage block to move. The movement of the linkage block compresses the limit spring. The limit spring deforms under the pressure, which causes the connecting rod to slide out into the installation box and be pulled to the maximum limit. Then the worker pushes the second cover and moves the second cover to contact the first cover.

[0015] Finally, the staff can release their grip on the lever. The linkage block loses pressure on the limit spring, and the limit spring then causes the linkage block to return to its original position. The return of the crossbar causes the limit block to move towards the first clamping block. The movement engages with the chamfer of the first and second clamping blocks, and then the spring rebounds and compresses, causing the tension spring to stretch and deform on both sides until the limit block smoothly enters between the first and second clamping blocks. The installation between the first and second covers is then completed. By setting the installation components, there is no need to tighten the bolts one by one as with bolt fixing. During installation, simply align the first and second covers and then pull them together to make the locking devices interlock, achieving a quick connection and greatly improving installation efficiency.

[0025] In this embodiment: the mounting component 6 includes a mounting frame 61, the mounting frame 61 is fixedly mounted on the side surface of the first cover 4, the mounting frame 61 is fixedly mounted on the side surface of the second cover 5, and a groove 62 is formed on the surface of the mounting frame 61.

[0026] Specifically, a sealing gasket 63 is fixedly connected to the inner wall of the groove 62. There are two sealing gaskets 63, which are symmetrically arranged at the center of the regulating valve body 1.

[0027] The effect achieved by the above components is that the sealing gasket 63 facilitates an increase in the sealing between the first cover 4 and the second cover 5.

[0028] Specifically, two positioning posts 64 are fixedly connected to the side surface of the first cover 4. The outer surface of the positioning post 64 is rotatably connected to a first clamping block 65. The side of the first clamping block 65 away from the positioning post 64 is fixedly connected to a first fixing rod 66. The outer surface of the other positioning post 64 is rotatably connected to a second clamping block 67. The side of the second clamping block 67 away from the positioning post 64 is fixedly connected to a second fixing rod 68. The outer surface of the first fixing rod 66 is fixedly connected to a tension spring 69. The side of the tension spring 69 away from the first fixing rod 66 is fixedly connected to the outer surface of the second fixing rod 68.

[0029] The effect achieved by the above components is that the distance between the first clamping block 65 and the second clamping block 67 can be easily controlled by the tension spring 69, so as to ensure that the position of the limiting block 616 can be restricted.

[0030] Specifically, the side surface of the second cover 5 is fixedly connected to the mounting box 610, which is rectangular in shape and has a linkage groove 611 inside.

[0031] The effect achieved by the above components is that the internal structure is easily installed through the mounting box 610.

[0032] Specifically, a limiting spring 612 is fixedly connected to the side of the linkage groove 611 away from the second cover 5, and a linkage block 613 is fixedly connected to the side of the limiting spring 612 away from the linkage groove 611. The linkage block 613 is rectangular and is slidably connected to the inner wall of the linkage groove 611. The linkage block 613 is in contact with the side surface of the second cover 5.

[0033] The effect achieved by the above components is that the limiting spring 612 facilitates the reset spring force of the linkage block 613 bracket, thereby ensuring that the position of the limiting block 616 can be restricted.

[0034] Specifically, a connecting rod 614 is fixedly connected to the side of the linkage block 613 near the limiting spring 612. The connecting rod 614 passes through the mounting box 610. A crossbar 615 is fixedly connected to the side of the connecting rod 614 away from the linkage block 613. The crossbar 615 contacts the side surface of the mounting box 610. Both ends of the crossbar 615 are arc-shaped and L-shaped. A limiting block 616 is fixedly connected to the end of the crossbar 615 away from the connecting rod 614. The limiting block 616 engages with the inner wall of the first clamping block 65 and the inner wall of the second clamping block 67. The limiting block 616 contacts the side surface of the second cover 5. There are two crossbars 615, which are symmetrically arranged at the center of the second cover 5.

[0035] The effect achieved by the above components is that the position between the first cover 4 and the second cover 5 can be easily fixed by the cooperation of the crossbar 615 and the limiting block 616.

[0036] Specifically, a tie rod 617 is fixedly connected to the side of the crossbar 615 away from the connecting rod 614.

[0037] The effect achieved by the above components is that the pull rod 617 makes it easier for the operator to operate the two crossbars 615 together, further increasing the efficiency of the installation between the first cover 4 and the second cover 5.

[0038] Working principle: When it is necessary to install the first cover 4 and the second cover 5, the worker first holds the pull rod 617 with one hand and pulls the pull rod 617 outward. Then the pull rod 617 drives the connecting rod 614 to move through the crossbar 615. The movement of the connecting rod 614 drives the linkage block 613 to move. The movement of the linkage block 613 compresses the limiting spring 612. The limiting spring 612 deforms under the pressure, which causes the connecting rod 614 to slide out into the mounting box 610 and be pulled to its maximum limit. Then the worker pushes the second cover 5 and moves the second cover 5 to contact the first cover 4.

[0039] Finally, the staff can release their grip on the lever 617. The linkage block 613 loses pressure on the limit spring 612, and the limit spring 612 drives the linkage block 613 to reset and rebound. The rebound of the crossbar 615 drives the limit block 616 to move towards the first clamping block 65. The movement engages with the chamfer of the first clamping block 65 and the second clamping block 67, and then rebounds and compresses, causing the tension spring 69 to stretch and deform on both sides until the limit block 616 smoothly enters between the first clamping block 65 and the second clamping block 67. Then the installation between the first cover 4 and the second cover 5 is completed. By setting the installation component 6, there is no need to tighten the bolts one by one as with bolt fixing. During installation, simply align the first cover and the second cover, and then a simple pulling operation can make the locking device lock together, achieving a quick connection and greatly improving the installation efficiency.
