DETAILED DESCRIPTION

[0018] The utility model is further explained below in combination with the drawings and embodiments.

[0021] Because the edge of positioning block 35 is sharp, it is inevitable to cause scratch on the surface of valve seat, therefore protective pad 5 can be arranged at the two side edges of positioning groove 36, when positioning block 35 is attached with valve seat, protective pad 5 wraps the edge of positioning block 35, to avoid that valve seat and other components contact with the edge of positioning block 35 and scratch.

[0022] It further includes oil injection unit 4, as Figure 3As shown, the oil bag 41 is fixedly connected to one side in the fixing frame 31, the oil bag 41 is filled with lubricating oil, and the oil bag 41 is provided with an oil supplement port, a conduit 43 is communicated with the top of the oil bag 41, the end of the conduit 43 corresponds to the assembly position, and the upper surface of the positioning block 35 on the same side of the oil bag 41 is fixedly connected with a push block 42, when the positioning block 35 is moved outward under the force of the valve seat, the positioning block 35 drives the push block 42 to move outward, the push block 42 will contact and extrude the oil bag 41, after the oil bag 41 is extruded, the internal lubricating oil enters the conduit 43, and finally drips into the inside of the valve seat guided by the conduit 43, so that the lubricating oil can be automatically injected into the valve seat during the assembly of the liquid inlet valve, the lubricity between components is increased, and the components are prevented from being jammed to cause the assembly process to be blocked.

[0023] As shown in the figure, Figure 4 Two supporting rods 44 are fixed at the same side position of the oil bag 41 in the fixing frame 31, the lower end of the supporting rod 44 is fixedly connected with a supporting ring 45, the conduit 43 passes through the two supporting rings 45 in turn, the supporting ring 45 supports the conduit 43, ensures that the end of the conduit 43 corresponds to the inside of the valve seat and other components, and the supporting rod 44 is used for keeping the supporting ring 45 fixed, so that the lubricating oil can be smoothly guided through the conduit 43 and enter the inside of the components to play a lubricating role; the supporting ring 45 is also provided with a silica gel ring 46, the silica gel ring 46 is fixedly connected with the supporting ring 45, the silica gel ring 46 isolates the conduit 43 from the supporting ring 45, the silica gel ring 46 protects the conduit 43, reduces the friction of the conduit 43, and better protects the conduit 43 from being worn.

[0024] In practical use, this utility model's inlet valve assembly, equipped with a top-pressing mechanism, first places the valve seat on the workbench 1. Then, the clamping component 22 clamps the valve sleeve component to be assembled. The top-pressing mechanism 2 then controls the clamping component 22 to move the assembly component towards the valve seat. The positioning component 3 and the clamping component 22 are lowered by the telescopic drive of the top-pressing mechanism 2. The positioning block 35 within the positioning component 3 preferentially contacts the valve seat. The positioning groove 36 adjusts the position of the valve seat through the conical clamping space and corresponds to the shape of the valve seat, moving the valve seat to the middle position. Then, the positioning block 35 continues to move downwards, simultaneously moving to both sides due to the reaction force of the valve seat, cooperating with the slide rod 32 to slide within the fixed frame 31. This allows the positioning component 3 to further position the valve seat, making the clamping component 22 more precise in assembling the components. By setting two positioning blocks 35 to assist the clamping component 22 in positioning the valve seat, the clamping component 22 can more accurately correspond to the center of the valve seat, enabling the clamping component 22 to assemble the inlet valve more quickly and accurately. At the same time, it can also assist in fixing the valve seat and improve the stability of the valve seat during assembly. When the positioning block 35 is moved outward by the force of the valve seat, it will drive the push block 42 to move. The push block 42 will squeeze the oil bladder 41. After the oil bladder 41 is squeezed, the lubricating oil is guided by the conduit 43 to drip into the interior of the valve seat, increasing the lubrication between the components and avoiding jamming between the components, which would hinder the assembly process. Example

[0025] Based on Example 1, such as Figure 5 As shown, multiple elastic ropes 6 are horizontally fixedly connected in the positioning groove 36. Multiple elastic balls 7 are slidably fitted in the middle of the elastic ropes 6. When the positioning groove 36 is in contact with the valve seat, the elastic ropes 6 are squeezed and stretched, and then also in contact with the valve seat surface. The elastic balls 7 will slide on the elastic ropes 6. Due to the pressure of the valve seat, the elastic balls 7 will be stuck into the gap of the valve seat. This can increase the stability of the positioning block 35 in contact with the valve seat, further improve the positioning accuracy of the positioning component 3 in positioning the valve seat, facilitate the clamping component 22 to quickly and accurately assemble the inlet valve, and improve the assembly efficiency of the inlet valve.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
