Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to an antifreeze water pump head. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes 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. There is usually water inside the pump head of the water pump.

[0003] When used in a low-temperature environment, if the water pump is working intermittently or paused, the water inside the pump head is prone to freeze. The breaking of hydrogen bonds in the water during the freezing process causes the distance between molecules to increase. Therefore, the volume of water will increase when it freezes, which will cause damage to the pump head. Utility Model Content

[0004] The utility model aims to solve the disadvantages in the prior art that the volume of water will increase when it freezes, thereby causing damage to the pump head, and proposes an antifreeze water pump head.

[0005] In order to achieve the above-mentioned objectives, the utility model adopts the following technical scheme: an antifreeze water pump head, comprising a pump head body and an antifreeze mechanism, the antifreeze mechanism comprising an antifreeze airbag, the antifreeze airbag comprising an airbag body, the inner wall of the airbag body being fixedly connected with an explosion-proof layer, the surface of the airbag body being fixedly connected with a wrapping layer, the surface of the wrapping layer being provided with a wear-resistant layer, the bottom of the antifreeze airbag being fixedly connected with connecting rods distributed in a rectangular array, the lower end surface of the connecting rod being provided with a connecting hole, the inner bottom wall of the connecting hole being fixedly connected with an elastic pad, and the top of the elastic pad being fixedly connected with a sliding head.

[0006] As a further description of the above technical solution:

[0007] The inner bottom wall of the pump head body is fixedly connected with a docking rod having the same position distribution as the connecting rod, and the upper end surface of the docking rod is inlaid with a wear-resistant ring.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the wear-resistant ring is tightly matched with the connecting rod, and the inner wall of the wear-resistant ring is fixedly connected with an insertion rod which is tightly matched with the connecting hole.

[0010] As a further description of the above technical solution:

[0011] The surface of the pump head body is coated with a protective paint layer, and the inner wall of the pump head body is provided with a corrosion-resistant layer.

[0012] As a further description of the above technical solution:

[0013] The top and bottom of the pump head body are both fixedly connected with protective seats, and the front and back sides of the pump head body are both provided with wear-resistant coatings.

[0014] As a further description of the above technical solution:

[0015] A connecting seat is fixedly connected to the front of the antifreeze air bag, and the interior of the connecting seat is communicated with the antifreeze air bag.

[0016] As a further description of the above technical solution:

[0017] A connecting pipe is fixedly connected to the surface of the connecting seat, and a protective coating is provided on the surface of the connecting pipe.

[0018] As a further description of the above technical solution:

[0019] One end of the connecting pipe is fixedly connected to an air intake pipe, and one end of the air intake pipe is provided with an external thread.

[0024] The utility model has the following beneficial effects:

[0025] 1. Compared with the prior art, the antifreeze water pump head inserts the connecting rod into the wear-resistant ring and inserts the plug rod into the connecting hole at the same time. The plug-in fixation is completed through the close cooperation between the connecting rod, the wear-resistant ring, the plug rod and the connecting hole. The plug-in method is convenient for installation and disassembly. When used in a low-temperature environment, ice forms inside the pump head, and the antifreeze air bag is deformed to cooperate, providing space for ice formation, making the pump head not easy to burst, thereby protecting the pump head.

[0026] 2. Compared with the prior art, the antifreeze water pump head has an explosion-proof layer that makes the antifreeze airbag less likely to explode. When ice forms, the wrapping layer protects the outside of the antifreeze airbag to prevent the antifreeze airbag from being damaged by freezing. The wear-resistant layer improves the wear resistance of the antifreeze airbag and increases the service life of the antifreeze airbag. When the water pump is working, the water pressure will compress and deform the antifreeze airbag, but will not completely flatten it, so that it can still deform to cooperate when it freezes.

During installation, the connecting rod 7 is inserted into the wear-resistant ring 12, and the insertion rod 13 is inserted into the connecting hole 8 at the same time. The plug-in fixation is completed through the close cooperation between the connecting rod 7, the wear-resistant ring 12, the insertion rod 13 and the connecting hole 8. The plug-in method is convenient for installation and disassembly. When used in a low-temperature environment, ice forms inside the pump head, and the antifreeze air bag 2 is deformed to cooperate, providing a space for ice formation, making it difficult for the pump head to burst, thereby protecting the pump head. The explosion-proof layer 4 makes it difficult for the antifreeze air bag 2 to explode. When ice forms, the wrapping layer 5 protects the outside of the antifreeze air bag 2 to prevent the antifreeze air bag 2 from being frozen. The wear-resistant layer 6 improves the wear resistance of the antifreeze air bag 2 and improves the service life of the antifreeze air bag 2.

[0039] The surface of the pump head body 1 is coated with a protective paint layer, which provides external protection for the surface of the pump head body 1, making the surface of the pump head body 1 not easy to rust. The inner wall of the pump head body 1 is provided with a corrosion-resistant layer, which improves the corrosion resistance of the inner wall of the pump head body 1. The top and bottom of the pump head body 1 are fixedly connected with a protective seat 19, and the front and back of the pump head body 1 are provided with a wear-resistant coating. The front of the antifreeze air bag 2 is fixedly connected with a connecting seat 14, and the interior of the connecting seat 14 is connected to the antifreeze air bag 2.

The surface of the connecting seat 14 is fixedly connected with the connecting pipe 15, and the surface of the connecting pipe 15 is provided with a protective coating. Layer, one end of the connecting pipe 15 is fixedly connected to the air intake pipe 16, one end of the air intake pipe 16 is provided with an external thread, and one end of the air intake pipe 16 is detachably connected to a sealing cap 17 through the external thread, and the surface of the sealing cap 17 is provided with an anti-slip pattern 18, and the anti-slip pattern 18 improves the anti-slip ability of the surface of the sealing cap 17, which is convenient for rotating the sealing cap 17, and the edges of the front and back sides of the antifreeze air bag 2 are set as chamfers.

When the water pump is working, the water pressure will compress and deform the antifreeze air bag 2, but will not completely flatten it, so that it can still send deformation to cooperate when freezing.

The plug-in method is convenient for installation and disassembly. When used in a low temperature environment, when the water pump is working, the water pressure will compress and deform the antifreeze air bag 2, but will not completely flatten it, so that it can still deform to cooperate when it is frozen, and ice will form inside the pump head, and the antifreeze air bag 2 will deform to cooperate, providing space for ice formation, so that the pump head is not easy to burst.
