[0002] A diaphragm pump is a special type of positive-displacement pump, and its working principle is to change the volume of the working chamber by the reciprocating agitation of a diaphragm, so as to suck and discharge the transported slurry or liquid medium.

[0003] The hydraulic pipe of a diaphragm pump generally refers to the pipe inside the diaphragm pump for transmitting liquid, which is one of the important components of the diaphragm pump. The hydraulic pipe is connected to the piston component and the front end of the power plate of the diaphragm pump. During the working process of the diaphragm pump, as the passage for liquid flow, the design and material of the hydraulic pipe have a direct impact on the performance of the pump.

[0004] In the prior art, the structure of the hydraulic pipe is as shown in the appendix Figure 1 As shown, both ends of the hydraulic pipe are cylindrical ends, and the two cylindrical ends are connected by a connecting part. When the hydraulic pipe of this structure is connected to the piston component, there is a problem of weak connection strength, and the hydraulic pipe is prone to deformation and damage during long-term use.

[0006] To solve the above technical problem, the utility model adopts the following technical scheme:

[0007] A spherical hydraulic pipe structure includes a first end, a second end and a connecting part. A first chamber is opened in the first end, a second chamber is opened in the second end, and a connecting chamber is opened in the connecting part. The first end and the second end are connected by the connecting part, and the first chamber, the connecting chamber and the second chamber are communicated in sequence. The first end is a hemispherical end, and a connecting stop and a plurality of connecting holes are opened on the end face of the first end. The plurality of connecting holes are evenly distributed circumferentially on the end face of the first end.

[0008] Preferably, the included angle between the axis of the connecting part and the axis of the second end is less than 90°.

[0009] Preferably, the included angle range between the axis of the connecting part and the axis of the second end is 60° - 90°.

[0010] Preferably, the outer contour dimension of the connecting portion gradually decreases from one end close to the first end to the other end far from the first end.

[0011] Preferably, one end of the connecting portion is smoothly connected to the corresponding position of the first end, and the other end of the connecting portion is smoothly connected to the corresponding position of the second end.

[0013] 1. In the present invention, the first end for connecting with the piston component is set as a hemispherical structure, and a connecting stop is provided on the end face of the first end of the hemispherical structure for connecting with the stop of the power end of the diaphragm pump. At the same time, a plurality of connecting holes are uniformly arranged in the circumferential direction on the end face of the first end, and the connection with the piston component is realized by using the connecting holes. The end design of the hemispherical structure can effectively improve the connection strength between the hydraulic pipe and the front plate of the power end of the diaphragm pump and the piston component, and reduce the deformation and damage probability of the hydraulic pipe during use.

[0014] 2. The first end connected to the piston component is designed as a hemispherical structure, and the end of the hemispherical structure can be used to accommodate a piston component with a larger diameter.

[0015] 3. In the hydraulic pipe structure of this solution, the included angle between the axis of the connecting portion and the axes of the two ends is less than 90°, which is beneficial to the flow of the hydraulic fluid, reduces the axial force acting on the hydraulic pipe by the piston component, and further reduces the deformation tendency of the hydraulic pipe, thereby improving the service life of the hydraulic pipe.

In actual use, the first end portion 1 is connected to the piston component and the front end of the power plate.
