Description

Technical Field

[0001] The utility model relates to the technical field of pumps and valves, in particular to a leakage-proof device for pump and valve joints which is easy to install. Background Art

[0002] Pumps and valves play different roles in fluid systems, but both are vital components. A pump is a machine used to transport liquids or pressurize liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. It can also transport liquids, gas mixtures and liquids containing suspended solids. The performance parameters of the pump mainly include flow rate, head, shaft power, efficiency, speed, etc. There are many types of pumps, which can be divided into positive displacement pumps, vane pumps and liquid dynamic pumps according to their working principles. Valves are fluid transport systems. The control components in the system have the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. There are many types of valves. According to the structural characteristics, they can be divided into shutoff valves, gate valves, plug valves, ball valves, butterfly valves, diaphragm valves, check valves, throttle valves, safety valves, pressure reducing valves, steam traps, regulating valves, etc. Pumps are mainly used for fluid transportation and pressurization, while valves are used to control the flow, pressure and flow direction of fluids. In the fluid system, the coordinated work of pumps and valves ensures the normal operation of the system and the effective management of fluids. The pump-valve connection is an important part of the installation process of pump-valve equipment, involving a variety of connection methods and steps;

[0003] Referring to the Chinese patent authorization announcement number CN220228215U, the authorization announcement date is 2023.12.22, which discloses a leakage prevention device for pump-valve joint. The utility model drives the fixing plate to move by rotating the locking bolt, so that the fixing plate and the sleeve plate are tightly fitted with the pump connecting pipe and the valve body connecting pipe, which can prevent leakage at the joint;

[0004] However, the utility model is inconvenient to operate when connecting pumps and valves of different diameters, which easily causes liquid to flow out of the joint of the pump and valve, thereby resulting in poor sealing effect, which is not conducive to the transportation of liquid and has a narrow application range;

[0005] Therefore, we propose a pump-valve joint leakage prevention device which is easy to install, so as to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide an easy-to-install anti-leakage device for pump-valve joints, so as to solve the problem raised in the above-mentioned background technology that the current utility model is inconvenient to operate when connecting pumps and valves of different diameters, which easily leads to liquid outflow at the joint of the pump and valve, thereby resulting in poor sealing effect, being unfavorable for liquid transportation, and having a narrow application range.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5The utility model provides a technical solution: a pump valve joint leak-proof device that is easy to install, comprising: a valve body connecting pipe 1, a pump body connecting pipe 2, a sealing gasket 3, a hollow hole 4, a fixing pipe 5, a locking bolt 6, a locking nut 7, a first connecting pipe 8, a connecting hole 9, a second connecting pipe 10, a limiting hole 11, a limiting ring 12, a threaded column 13 and a convex ring 14;

[0029] When using this easy-to-install pump-valve joint leak prevention device, if Figure 1 and Figure 4 As shown, the pump body connecting pipe 2 is fixedly installed on the pump body, and four fixing pipes 5 are preliminarily connected together at the lower side of the pump body connecting pipe 2. Because the first connecting pipe 8 is provided on one side of the fixing pipe 5, and the second connecting pipe 10 is provided on the other side, and the first connecting pipe 8 and the second connecting pipe 10 are vertically arranged, a limiting hole 11 is provided inside the second connecting pipe 10, and the limiting hole 11 is rotatably connected to a limiting ring 12 fixedly connected to one end of the threaded column 13, so the threaded column 13 is rotatably connected to the second connecting pipe 10, and the limiting ring 12 plays a limiting role to prevent the threaded column 13 from slipping out of the second connecting pipe 10;

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first connect any two fixed tubes 5 together, thread the threaded column 13 on one fixed tube 5 to the connecting hole 9 opened in the first connecting tube 8 on the other fixed tube 5, and ensure that the first connecting tube 8 and the second connecting tube 10 of the two connected fixed tubes 5 face the same side, and then preliminarily connect the other two fixed tubes 5 together in the same way, and also make the first connecting tube 8 and the second connecting tube 10 on the fixed tube 5 face the same side, and the fixed tubes 5 are not divided into the front and back sides, and then connect the two connected fixed tubes 5 together respectively, at this time, the lower side of the pump body connecting tube 2 is preliminarily connected to four fixed tubes 5;

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, four fixed tubes 5 are connected together on the upper side of the valve body connecting tube 1 in the same way. At this time, the upper side of the valve body connecting tube 1 and the lower side of the pump body connecting tube 2 are both provided with fixed tubes 5 for clamping. The sealing gasket 3 is placed just above the pump body connecting tube 2 to ensure that the center point of the sealing gasket 3 is consistent with the center point of the pump body connecting tube 2. Then, the valve body connecting tube 1 is docked on the upper side of the sealing gasket 3. According to the actual diameters of the valve body connecting tube 1 and the pump body connecting tube 2, the fixed tube 5 on the side with a larger diameter is tightened first, and the fixed tube 5 on the side with a smaller diameter is subsequently adjusted according to the fixed tube 5 with a larger diameter.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, each side of the threaded column 13 is fixedly connected with a convex ring 14. Turning the convex ring 14 by hand cannot ensure that the threaded column 13 is tightly connected to the connecting hole 9. Use a tool to turn the convex ring 14 to connect the threaded column 13 to the connecting hole 9. After the fixing tube 5 on the side with a larger diameter is tightened, the fixing tube 5 on the side with a smaller diameter is fine-tuned, and then the locking bolt 6 is inserted into the fixing tube 5 on the side of the valve body connecting tube 1. After making appropriate adjustments, the locking bolt 6 is also installed in the remaining fixing tubes 5, and then the locking bolt 6 is tightened. The tightening nut 7 is screwed to the lower side of the locking bolt 6. As the locking bolt 6 and the locking nut 7 are tightly connected, the sealing gasket 3 will also be squeezed. A hollow hole 4 is provided inside the sealing gasket 3, and the thickness of the inner end of the sealing gasket 3 is thinner than that of the outer end. When the sealing gasket 3 is squeezed, the hollow hole 4 will be deformed, and a closed space will gradually be formed between the valve body connecting pipe 1 and the pump body connecting pipe 2. At this time, the valve body connecting pipe 1 and the pump body connecting pipe 2 are connected together by the fixing pipe 5, the locking bolt 6 and the locking nut 7, and are convenient for installation.
