It also includes: The tee has its first and second interfaces connected to the main pipe, respectively. The inlet of the switch valve is connected to the third interface of the tee, and the outlet is connected to the inlet of the feed pipe. A buffer, used to buffer pressure surges in pipelines, the buffer comprising: The buffer housing has a sealed cavity inside, and a diaphragm is installed inside the cavity, which divides the cavity into independent liquid and gas chambers. The tee is provided with a connection port that connects to the main pipeline, and the buffer housing is provided with a connector that connects to the liquid chamber. The connector is connected to the connection port.

[0005] Furthermore, it also includes pigpen guardrails installed on both sides of the pigpen aisle and at the front of the liquid feed trough.

[0006] Furthermore, the aforementioned switching valve is an electrically operated switching valve.

[0012] Furthermore, the aforementioned buffer housing is provided with an air outlet that communicates with the air chamber, and a plug is sealed and fixed to the buffer housing at the air outlet.

[0013] The beneficial effects of this utility model are: when the required feeding amount is reached, the switch valve is closed. At this time, the local pressure in the main pipeline increases, the volume of the liquid chamber in the buffer increases, and the diaphragm deforms and squeezes the air chamber. The air chamber is compressed and its volume decreases, thereby effectively buffering the instantaneous pressure impact inside the main pipeline, thereby achieving the purpose of protecting the switch valve and improving the stability of the liquid feed feeding system.

[0015] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be further described below.

[0016] A liquid feed terminal for pigs with a buffer function includes liquid feed troughs 3 set on both sides of the pigsty aisle 1, a main pipeline 4 for conveying liquid feed, and a feed pipe 7 located above the liquid feed troughs 3 and connected to the outlet end of the liquid feed troughs 3. It also includes: a tee 5, whose first and second interfaces are respectively connected to the main pipeline 4; a switch valve 6, whose inlet end is connected to the third interface end of the tee 5 and whose outlet end is connected to the inlet end of the feed pipe 7; and a buffer 8 for buffering pressure impacts in the pipeline. The buffer 8 includes: a buffer housing 801, which has a sealed cavity inside. A diaphragm 803 is installed inside the cavity, dividing the cavity into an independent liquid cavity 806 and an air cavity 805. The tee 5 has a connection port 501 connected to the main pipeline 4, and the buffer housing 801 has a connector 804 connected to the liquid cavity 806. The connector 804 is connected to the connection port 501. During feeding, the switch valve 6 is opened, and liquid feed enters the liquid feed trough 3 through the main pipeline 4, the tee 5, and the feed pipe 7. When the required feeding amount is reached, the switch valve 6 is closed. At this time, the local pressure in the main pipeline 4 increases, and the volume of the liquid chamber 806 in the buffer 8 increases. At this time, the diaphragm 803 deforms and squeezes the air chamber 805, which is compressed and its volume decreases. This effectively buffers the instantaneous pressure impact inside the main pipeline 4, thereby protecting the switch valve 6 and improving the stability of the liquid feed feeding system. The structure is simple, stable, and durable, and requires no maintenance during the service life of the liquid feed feeding system.

[0019] In one embodiment of this utility model, the buffer housing 801 is made of stainless steel. The diaphragm 803 is made of polytetrafluoroethylene (PTFE). The stainless steel buffer housing 801 has strong corrosion resistance and does not contaminate feed, improving its reliability. The PTFE diaphragm 803 has excellent heat and cold resistance, and can be used for a long time in environments ranging from -180 to 260°C. Furthermore, PTFE is resistant to acids and alkalis and is insoluble in all volumes, further improving its reliability.
