The flow divider B400 decompresses the high-pressure fluid after passing through the tapered valve body and is buffered by a buffering filter screen with the size of about B100 meshes, so that the impact of the fluid is effectively reduced. For medicinal fluids, some of the fluids can generate foam after flowing at high pressure and high speed, and the foam generation can be effectively reduced and lowered.

Further optimizing, the diameter of the canning hole B610 is in a structure with a small upper part and a large lower part.

The traditional canned valve core B120 is an integral part, so that the traditional canned valve core B120 is easy to damage due to the fact that the traditional canned valve core B120 is required to bear high-pressure fluid and the pressure of a spring on one hand and the pressure of a contact post B123 on the other hand, the traditional canned valve core B is guaranteed to work in a sealing mode and plays a protective role, and meanwhile the later maintenance cost is reduced.

The high-pressure fluid is easy to form backflush and splash after flowing out from the filling head and impacting the tank bottom, and the flow rate of the liquid is obviously reduced after passing through the flow divider B400 and the buffer filter screen B500, so that impact is not easy to form.

Referring to fig. 14, the limit nut C400 moves downward by a certain position under the rotation of the adjusting handle C600, at this time, it is obvious that the effective volume of the liquid cavity C110 is increased, and conversely, it is decreased, that is, the initial position downward movement measurement of the plunger body C200 is increased, and the position upward movement measurement of the plunger body C200 is decreased.
