Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0023] This embodiment is an improved water pump casing, such as... Figures 1 to 6 As shown, the pump includes an integrally formed pump housing 1, an inlet pipe 2, and an outlet pipe 3. The pump housing 1 is annular, with one end connected to a motor. The inlet pipe 2 and the outlet pipe 3 are located at the top of the pump housing 1. A first vent valve 4 is disposed at the top of the inlet pipe 2 from top to bottom, and a second vent valve 5 is disposed at the side of the outlet pipe 3 from top to bottom. The inlet pipe 2 has two openings, one at the top and the other at the side, with the one at the side forming the inlet.

[0024] In this application, the inlet pipe 2 and outlet pipe 3 are located at the top of the pump housing 1, which facilitates the entry of gas located at a high position into the inlet pipe 2 and outlet pipe 3. When water enters the pump housing 1 from the inlet pipe 2, it easily pushes the gas to a high position in the inlet pipe 2. The first exhaust valve 4 is set at the top of the inlet pipe 2, which can effectively prevent the gas at a high position from remaining. When water rushes out of the pump housing 1, most of the gas can be discharged from the pump body with the water flow, but some gas still adheres to the inner wall of the outlet pipe 3. The second exhaust valve 5 is set on the side of the outlet pipe 3 in this application, which can further improve the exhaust effect. In summary, the first exhaust valve 4 and the second exhaust valve 5 set in appropriate positions in this application can effectively improve the exhaust effect.

[0025] The main body part of the pump body with the built-in impeller can be arranged at the middle part of the pump housing 1, and the axial dimension is not limited, so the improved pump housing of the water pump can be adapted to the main body parts of pump bodies with different stages.

[0026] The top surface of the water inlet pipe 2 is provided with an end cover 6, the inside of the water inlet pipe 2 is provided with a partition cavity wall 21, and the end cover 6 and the partition cavity wall 21 are provided with a valve core 7. The valve core 7 functions as a one-way valve, so that water can only flow into the water inlet pipe 2 in one direction and cannot flow out in one direction. The contact part of the valve core 7 and the end cover 6 is provided with a copper insert 71, which is a ring-shaped part. The valve core 7 is made of plastic material and is easily worn during contact with the end cover 6. The copper insert 71 plays a local strengthening role and is made of copper material, has good friction resistance, and can improve the service life of the valve core 7. In this embodiment, the inside of the valve core 7 is provided with a ring-shaped step, and the copper insert 71 is arranged at the ring-shaped step.

[0027] The end cover 6 is connected with an extension column 61 extending from top to bottom, the partition cavity wall 21 has a communication hole 211, one end of the valve core 7 is inserted into the extension column 61 and can move along the extension column 61, and the other end of the valve core 7 is movably connected at the communication hole 211. When one end of the valve core 7 moves along the extension column 61, the other end of the valve core 7 blocks or leaves the communication hole 211. Water flowing into the water inlet pipe 2 pushes the valve core 7 open, so that water can flow into the pump housing 1 through the communication hole 211.

[0028] The first exhaust valve 4 is connected to the end cover 6 by screwing, the end cover 6 is connected to the top of the water inlet pipe 2 by a threaded cover 8, and the first exhaust valve 4 is arranged side by side with the valve core 7. In this arrangement, the first exhaust valve 4 and the end cover 6 are detachable structures, which are convenient for disassembly and exhaust. The edge of the end cover 6 is provided with a flange, and the threaded cover 8 is connected to the top of the water inlet pipe 2 by screwing. The top can limit the flange of the end cover 6, which can effectively prevent the end cover 6 from falling out.

[0029] The side surface of the water inlet pipe 2 is provided with a water inlet, and the water inlet is provided with a blocking net 22. The blocking net 22 can effectively prevent sundries from entering the water inlet pipe 2. In the actual working environment, there may be sundries with a larger volume. Once such sundries enter the pump body, they will affect the normal work of the pump body, so it is necessary to use the blocking net 22 to block them.

[0030] The pump housing 1 has an annular partition wall 11, the connection between the water inlet pipe 2 and the pump housing 1 has a first communication port 12, the connection between the water outlet pipe 3 and the pump housing 1 has a second communication port 13, and the first communication port 12 and the second communication port 13 are separated on both sides of the annular partition wall 11. The annular partition wall 11 separates the first communication port 12 and the second communication port 13, which can effectively reduce the turbulence and noise caused by the collision of water flow in different directions.

[0031] The water outlet pipe 3 is provided with an exhaust pipe 31, the opening of the exhaust pipe 31 faces upward, and the second exhaust valve 5 is threadedly connected to the opening of the exhaust pipe 31. By loosening the second exhaust valve 5, the gas can be discharged.

[0032] The water inlet pipe 2 and the water outlet pipe 3 are provided with a mounting position, and the pressure sensor 9 is arranged from top to bottom at the mounting position. The size of the mounting position needs to be reasonable, and cannot be too large or too small. If it is too large, it will occupy the position of the water inlet pipe and the water outlet pipe, and if it is too small, it will bring difficulty to the molding and is not convenient for accurate measurement of the pressure sensor 9.

[0033] The outer surfaces of the first exhaust valve 4 and the second exhaust valve 5 are provided with protrusions to facilitate picking up and applying force. In the embodiment, the protrusions form a cross shape, which is convenient for handheld force application, and no additional tool is needed for operation.
