Technical Field

[0001] The utility model relates to the technical field of water pump cover components, in particular to a water pump cover component with good sealing performance. Background Art

[0002] The water pump cover is an important part of the water pump. After installation, the water pump cover can prevent fluid leakage, ensure the stability of the pressure inside the water pump, and prevent water or other media from overflowing. It can also support other parts of the pump, play a supporting and fixing role, and ensure that the parts inside the water pump are in the correct position. The water pump cover can be divided into many different types according to different uses and structures, such as ordinary pump covers, flange pump covers, clamp pump covers, etc. In terms of materials, water pump covers are usually made of cast iron, cast steel, stainless steel, non-ferrous metals, etc. to ensure its strength and corrosion resistance.

[0003] When installing, the existing water pump cover assembly is mostly sealed by an annular sealing ring. The sealing structure is relatively simple, cannot form a close seal, and cannot maintain good sealing under different conditions; it cannot effectively reduce the risk of leakage.

[0019] 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.

[0020] See also Figure 1 , 2As shown in Figures 3 and 4, the utility model provides a technical solution: a water pump cover assembly with good sealing performance, comprising: an upper cover 1, the upper cover 1 is a cavity with an opening at the bottom; a lower cover 2 is installed on the bottom of the upper cover 1 by screws; a sealing gasket 3 is placed between the upper cover 1 and the lower cover 2, a sealing ring 6 is vertically provided on the top of the sealing gasket 3, the sealing ring 6 and the sealing gasket 3 are both made of rubber material, an extrusion ring 4 with an elastic structure is obliquely provided on the outer side of the sealing gasket 3, when the upper cover 1 and the lower cover 2 are assembled, the extrusion ring 4 contacts the upper cover 1 and squeezes out the internal air so that the extrusion ring 4 and the upper cover 1 fit and seal.

[0021] It should be noted that when the utility model is installed, the sealing gasket 3 is buckled on the end of the upper cover 1 so that the sealing ring 6 is embedded in the upper cover 1. When the sealing gasket 3 and the upper cover 1 are squeezed and fitted, the sealing ring 6 is deformed under the action of pressure so that a sealed space is formed between the sealing ring 6, the extrusion ring 4 and the end of the upper cover 1, and the air in the space is squeezed out so that it is adsorbed on the end of the upper cover 1 like a suction cup, thereby ensuring the sealing of the connection, and ensuring the stability and reliability of the water pump in a high pressure or vibration environment. Then the lower cover 2 is covered on the bottom of the sealing gasket 3, and the two are connected by screws.

[0022] See also Figure 2 As shown, a sealing groove 8 cooperating with the sealing ring 6 is provided at the bottom of the upper cover 1 .

[0023] It should be noted that the top of the upper cover 1 of the utility model is provided with two openings, and the outer side of the opening is threadedly connected with a sealing cover. During installation, the sealing ring 6 is inserted into the sealing groove 8. The sealing groove provides an exact position and shape for the sealing ring, so that the sealing ring can be accurately embedded, which helps to enhance the sealing effect, because it can better limit the movement of the sealing ring and reduce the risk of leakage, so that a sealed space is formed between the sealing ring 6, the extrusion ring 4 and the end of the upper cover 1. When the sealing ring 6 and the sealing groove 8 are fully matched, the extrusion ring 4 and the upper cover 1 are lifted by extrusion. The contact surface between the two can be increased through the sealing groove 8 and the sealing ring 6, thereby improving its sealing performance. The use of the sealing groove 8 and the sealing ring 6 not only physically increases the contact area, but also enhances the sealing effect through shape matching, thereby preventing any movement or deformation of the sealing ring during use.

[0024] See also Figure 3 As shown, a support ring 5 is fixedly connected to the bottom of the sealing gasket 3 for providing tension while sealing, and a slot hole for use with the support ring 5 is provided on the top of the lower cover 2.

[0025] It should be noted that the sealing gasket 3 of the utility model not only acts as a sealing component to prevent the leakage of liquid or gas, but also has a support ring 5 fixed to its bottom. The support ring 5 provides the necessary tension while sealing, making it similar to a spring gasket, and can ensure sufficient pressure between components while sealing to prevent loosening and leakage, especially in an environment where mechanical vibration or temperature change may cause the components to loosen. The top of the lower cover 2 is designed with a slot hole, which is specifically used to cooperate with the support ring 5. When the lower cover 2 cooperates with the sealing gasket 3, the support ring 5 is inserted into the slot hole. This structural design not only increases the contact area, thereby improving the sealing performance, but also provides additional mechanical tension through the elasticity of the support ring. Improvement of stability and sealing performance: Through the elasticity of the support ring 5, the entire assembly structure can work like a spring gasket, providing stable tension for the lower cover 2, which helps to resist potential loosening caused by vibration or thermal expansion. The stability of the connection between the upper cover 1 and the lower cover 2 through screws is guaranteed, and the possibility of frequent maintenance is reduced, especially in high-pressure or high-load working environments.

[0026] See also Figure 1 As shown, a plurality of positioning shafts 7 are fixedly connected to the top of the lower cover 2 at equal distances, a positioning hole matching with the positioning shaft 7 is provided at the bottom of the upper cover 1, the positioning shaft 7 is located on the outside of the sealing ring 6, a through hole is installed in the middle of the lower cover 2, and the through hole and the positioning shaft 7 are staggered.

[0027] It should be noted that a plurality of positioning shafts 7 are equidistantly fixed on the top of the lower cover 2 of the utility model. The positioning shafts are used to ensure the correct position and alignment of each component during the assembly process. When the upper cover and the lower cover are combined, the positioning shafts are inserted into the corresponding positioning holes to ensure precise alignment between the two, reduce assembly errors, and improve production and assembly efficiency. The positioning shaft 7 is located on the outside of the sealing ring 6, and the two complement each other. The sealing ring forms an effective seal between the two covers without being interfered by the positioning shaft.
