At this time, the electromagnet has magnetic force and will attract the magnetic block, so that the gap of the insertion plate moves to the bottom of the blocking block. After that, the electromagnet stops working, and the gravity of the blocking block causes it to slide downward and enter the gap, so that the entire pipeline mechanism is fixed. 4. The present invention provides a connecting mechanism. When the pipeline mechanism needs to be disassembled, the electromagnet generates magnetic force again, so that the magnetic block and the blocking block move upward and leave the gap, so that the entire pipeline mechanism can be taken out.

Due to the different pressures on the upper and lower sides of the partition 4, the partition 4 is driven to move up and down, and the sliding column 3 and the diaphragm block 5 at the bottom are driven to move, thereby controlling the passage of the fluid. When it is necessary to install the pipeline mechanism 7 on the valve body 1, the pipeline mechanism 7 will be assembled with the connecting mechanism 6, and the pipeline mechanism 7 will also be automatically connected to the specific equipment pipeline thread, thereby realizing the overall installation.

[0030] like Figure 4 As shown, the pipeline mechanism 7 includes a support plate 71, an outer surface of the support plate 71 is fixedly connected to an insert plate 72, a notch 73 is provided on the insert plate 72, an end of the support plate 71 away from the insert plate 72 is fixedly connected to a fluid tube 74, an outer surface of the fluid tube 74 is evenly provided with mounting mechanisms 75, and an end of the fluid tube 74 away from the support plate 71 is fixedly connected to a port mechanism 76.

[0031] The side of the support plate 71 close to the insert plate 72 contacts the outer surface of the receiving mechanism 6 , and the outer surface of the partition plate 4 is slidably connected to the inner wall of the valve body 1 .

[0032] like Figure 5-Figure 6As shown, the port mechanism 76 includes an end plate 761, the outer surface of the end plate 761 is evenly provided with a circular tube 762, the inner wall of the circular tube 762 is provided with a power-assisting thread 763, the inner wall of the end plate 761 is evenly provided with a fixing thread 764, one end of the end plate 761 close to the fixing thread 764 is fixedly connected to a support block 765, and the outer surface of the support block 765 is fixedly connected to a sharp corner 766.

[0033] Before the screw 757 enters the fixing thread 764 , the screw 757 will come into contact with the sharp corner 766 , thereby removing dust and stains adhering to the screw 757 and preventing the dust on the screw 757 from obstructing the engagement of the screw 757 with the fixing thread 764 .

[0034] like Figure 7-Figure 8 As shown, the mounting mechanism 75 includes a second support plate 751, an end of the second support plate 751 close to the end plate 761 is fixedly connected to a telescopic rod 752, an end of the telescopic rod 752 away from the second support plate 751 is fixedly connected to a sleeve block 753, an inner wall of the sleeve block 753 is rotatably connected to a rotating block 754, an outer surface of the rotating block 754 is fixedly connected to a third support plate 755, an outer surface of the support plate 3 755 is fixedly connected to a protruding block 756, and an end of the rotating block 754 away from the sleeve block 753 is fixedly connected to a screw 757.

[0035] When the start-up diaphragm valve needs to be installed on a specific device, first align the end plate 761 with the pipe of the device, and align the threaded opening on the equipment pipe with the fixed thread 764 on the end plate 761. The telescopic rod 752 will move toward the end plate 761, thereby driving the sleeve block 753 and the rotating block 754 to move into the circular sleeve. After that, the protruding block 756 on the support plate three 755 will come into contact with the auxiliary thread 763 on the circular sleeve. As the telescopic rod 752 pushes, the rotating block 754 will rotate, thereby driving the screw 757 to rotate into the fixed thread 764 and the threaded opening on the specific device, thereby achieving installation. When disassembly is required, pulling the telescopic rod 752 back will achieve the opposite movement effect, thereby achieving disassembly.

[0036] In this way, there is no need to manually turn the screw 757 to install and disassemble the diaphragm valve, thereby improving the efficiency of installation and disassembly.

[0037] The outer surface of the end plate 761 is fixedly connected to one end of the fluid tube 74 away from the support plate 1 71 , and one end of the support plate 2 751 is fixedly connected to the outer surface of the fluid tube 74 .

[0038] The outer surface of the protruding block 756 contacts the assisting thread 763 , and the outer surface of the screw 757 meshes with the inner wall of the fixing thread 764 .

[0039] The specific workflow is as follows: During operation, when it is necessary to install the start diaphragm valve on a specific device, first align the end plate 761 with the pipe of the device, and align the threaded opening on the equipment pipe with the fixed thread 764 on the end plate 761, the telescopic rod 752 will move toward the end plate 761, thereby driving the sleeve block 753 and the rotating block 754 to move into the circular sleeve, and then the protruding block 756 on the support plate three 755 will come into contact with the auxiliary thread 763 on the circular sleeve, and as the telescopic rod 752 pushes, the rotating block 754 will rotate, thereby driving the screw 757 to rotate into the fixed thread 764 and the threaded opening on the specific device, thereby achieving installation. When disassembly is required, pulling the telescopic rod 752 back will achieve the opposite movement effect, thereby achieving disassembly. Before the screw 757 enters the fixed thread 764, the screw 757 will come into contact with the sharp corner 766, thereby removing the dust and stains attached to the screw 757, and preventing the dust on the screw 757 from hindering the screw 757 from engaging with the fixed thread 764.

[0040] Embodiment 2, use Figure 1-Figure 9 A pneumatic diaphragm valve that is easy to install according to one embodiment of the present invention is described as follows.

[0041] like Fig. 9 As shown, a pneumatic diaphragm valve that is easy to install of the present invention is based on the first embodiment. The connecting mechanism 6 includes an outer block 61, the top of the outer block 61 is provided with an inner cavity 62, the top of the inner cavity 62 is fixedly connected with an electromagnet 66, the top of the inner cavity 62 is symmetrically provided with support columns 63, the outer surface of the support column 63 is slidably connected with a stop block 64, and the top of the stop block 64 is fixedly connected with a magnetic block 65.

[0042] The outer surface of the outer block 61 is fixedly connected to the bottom of the valve body 1 , and the bottom of the support column 63 is not in contact with the bottom of the inner cavity 62 .

[0043] One end of the outer block 61 away from the valve body 1 contacts the support plate 71 , and the outer surface of the insert plate 72 is slidably connected to the inner cavity 62 .

[0044] The bottom of the blocking block 64 contacts the bottom of the inner cavity 62 , and the outer surface of the blocking block 64 is slidably connected to the inner wall of the notch 73 .

[0045] Since diaphragm valves are usually used to transport various corrosive chemicals, suspensions, high-viscosity liquids, etc., the diaphragm valve needs to be cleaned after a period of use, so the pipes on both sides of the bottom of the valve body 1 can also be disassembled and installed. When installation is required, by aligning the support plate 71 and the outer fastener, and inserting the insertion plate 72 into the inner cavity 62, the electromagnet 66 is magnetic at this time, and will attract the magnetic block 65, so that the gap 73 of the insertion plate 72 moves to the bottom of the stop block 64, and then the electromagnet 66 will stop working, and the gravity of the stop block 64 will cause it to slide downward and enter the gap 73, so that the overall pipeline mechanism 7 is fixed. When disassembly is required, the electromagnet 66 generates magnetic force again, so that the magnetic block 65 and the stop block 64 move upward and leave the gap 73, so that the overall pipeline mechanism 7 can be taken out.

[0046] The specific workflow is as follows: When installation or disassembly is required, the support plate 71 is aligned with the outer fastener, and the insertion plate 72 is inserted into the inner cavity 62. At this time, the electromagnet 66 has magnetic force and will attract the magnetic block 65, so that the gap 73 of the insertion plate 72 moves to the bottom of the stop block 64. After that, the electromagnet 66 will stop working, and the gravity of the stop block 64 will cause it to slide downward and enter the gap 73, so that the entire pipeline mechanism 7 is fixed. When disassembly is required, the electromagnet 66 generates magnetic force again, so that the magnetic block 65 and the stop block 64 move upward and leave the gap 73, so that the entire pipeline mechanism 7 can be taken out.

[0047] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
