Specific implementation manner

[0030] 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.

[0031] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a pressure controller that is convenient for installation, including a controller body 1. A water outlet pipe 2 is communicated with the surface of the controller body 1. A water inlet pipe 3 is communicated with the side of the controller body 1 away from the water outlet pipe 2. A power cord port 4 is communicated with the side surface of the controller body 1. A connection line port 5 is communicated with the side of the controller body 1 close to the power cord port 4. A connection device 6 is provided on the surface of the controller body 1, and a closing device 7 is provided on the surface of the moving cylinder 61.

[0032] Next, specifically describe the specific settings and functions of its connection device 6 and closing device 7.

[0033] As Figures 1 - 4 shown, the connection device 6 includes two fixing rings 64, and the two fixing rings 64 are respectively fixedly connected to the surfaces of the water outlet pipe 2 and the water inlet pipe 3. Moving cylinders 61 are sleeved on the surfaces of the water outlet pipe 2 and the water inlet pipe 3, and a sealing gasket 63 is adhesively connected to the inner wall of the moving cylinder 61. The moving cylinders 61 sleeved on the surfaces of the water outlet pipe 2 and the water inlet pipe 3 can move. By providing the moving cylinders 61 and the sealing gasket 63, the connection part can be sealed after connecting the controller body 1 and the water pump. A first arc-shaped plate 65 is fixedly connected to the surface of the moving cylinder 61, and a first screw 66 is threadedly inserted into the inner wall of the first arc-shaped plate 65, and the first screw 66 is rotatably connected to the controller body 1. By providing the first arc-shaped plate 65, the first screw 66 can be connected to the controller body 1 and the moving cylinder 61, and by rotating the first screw 66, the position of the moving cylinder 61 can be controlled and adjusted.

[0034] The surface of the moving cylinder 61 is fixedly connected with a second arc plate 67, and the inner wall of the second arc plate 67 is slidably connected with a slide bar 68, and the slide bar 68 is fixedly connected to the controller body 1. The slide bar 68 slidably connected to the inner wall of the second arc plate 67 will not affect the movement of the second arc plate 67 and the moving cylinder 61. By setting the slide bar 68, the stability of the moving cylinder 61 during movement can be improved. The end of the slide bar 68 away from the controller body 1 is fixedly connected with a limiting plate 69, and the end of the moving cylinder 61 away from the fixed ring 64 is fixedly connected with a butt ring 62. By setting the butt ring 62, the movement of the moving cylinder 61 can be limited, which is convenient for positioning the moving cylinder 61 by using the fixed ring 64 when moving. At the same time, the sealing effect can be improved by the fixed ring 64 and the butt ring 62.

[0035] like Figure 1 and Figure 2 as well as Figure 4 and Figure 5 As shown, the sealing device 7 includes four pressing plates 71, which are all slidably connected to the surface of the moving cylinder 61, and the four pressing plates 71 are fixedly connected to the sides away from the sealing gasket 63 with a fixing block 76, and the fixing block 76 is rotatably connected to the side away from the pressing plate 71 with a second screw rod 75. By providing the second screw rod 75, the movement of the pressing plate 71 can be controlled, and by providing the pressing plate 71, the sealing effect of the sealing gasket 63 can be improved.

[0036] Two "L"-shaped plates 74 are fixedly connected to the surface of the moving cylinder 61, and the two "L"-shaped plates 74 are both threadedly sleeved on the surface of the second screw rod 75. The surface of the second screw rod 75 is sleeved with a stabilizing plate 77, and the stabilizing plate 77 is fixedly connected to the "L"-shaped plate 74. By providing the "L"-shaped plate 74, the second screw rod 75 can be connected to the moving cylinder 61, and by providing the stabilizing plate 77, the stability of the second screw rod 75 during rotation can be improved. Two rectangular plates 72 are fixedly connected to one side of the moving cylinder 61 close to the pressure plate 71, and protrusions 73 are fixedly connected to both sides of the two rectangular plates 72. By providing the rectangular plates 72 and the protrusions 73, the sealing effect can be improved in cooperation with the pressure plate 71, thereby avoiding leakage as much as possible.

[0037] Working principle: When installing the pressure controller on the water pump, first move the water inlet pipe 3 of the controller body 1 close to the water pump, rotate the controller body 1 to connect it to the water pump. Then rotate the first screw rod 66 so that it rotates on the inner wall of the first arc-shaped plate 65 and the surface of the controller body 1, thereby controlling the movement of the moving cylinder 61 and the abutting ring 62 to move closer to the fixed ring 64. At this time, the second arc-shaped plate 67 slides on the surface of the slide rod 68, and the second arc-shaped plate 67 moves closer to the limit plate 69, so that the sealing gasket 63 seals the interface. Then install the wire connecting the power supply to the controller body 1 through the power supply wire port 4, connect the water pump and the controller body 1 through the connecting wire port 5, and then connect it to the water outlet pipeline through the water outlet pipe 2. By setting the connecting device 6, when connecting the pressure controller to the water pump, the use of raw tape can be avoided, so that the installation of the pressure controller can be facilitated, the installation efficiency of the pressure controller is improved, and the sealing performance after connection is ensured as much as possible.

[0038] After completing the connection between the pressure controller and the water pump, rotate the second screw rod 75 so that it rotates on the inner wall of the "L"-shaped plate 74. At this time, the second screw rod 75 rotates on the surface of the fixed block 76, thereby controlling the movement of the pressing plate 71 to move closer to the rectangular plate 72 and the convex block 73, so that the sealing gasket 63 is tightly attached to the surfaces of the water inlet pipe 3 and the water outlet pipe 2 under the extrusion of the pressing plate 71, the rectangular plate 72 and the convex block 73, thereby improving the sealing effect. By setting the stabilizing plate 77, the stability of the pressing plate 71 during movement can be improved. By setting the sealing device 7, after connecting the pressure controller to the water pump, the fitting degree between the sealing gasket 63 and the connecting pipe can be improved, so that it can be ensured as much as possible that no water leakage occurs after installing the controller body 1 on the water pump.
