Problems solved by technology
After the diaphragm vacuum pump has been used for a period of time, it is easy to cause the suction to weaken due to the damage of the diaphragm. If it is not found and dealt with in time, it will not only affect the working efficiency of the diaphragm vacuum pump, but also easily cause damage to other components.
[0004] In the prior art, although there are tools dedicated to the suction detection of diaphragm vacuum pumps, only by active detection can it be judged whether there is a problem with the suction. Frequent detection is troublesome, time-consuming and labor-intensive, and has poor practicability

The invention discloses a diaphragm vacuum pump pipe joint with a suction force self-detecting function, and belongs to the technical field of pipe joints. The pipe joint has the suction force self-detecting function, suction force of a diaphragm vacuum pump can be automatically detected every time the diaphragm vacuum pump is started, if a worker can observe light reflection of a suction detection elastic film, the diaphragm vacuum pump is insufficient in suction force, otherwise, if the suction force of the diaphragm vacuum pump is normal, a plug ring piston head is separated from an unblocking adjusting ring under the suction force of the vacuum pump, so that a detection adjusting pipe is conducted, and the diaphragm vacuum pump can operate normally. Compared with the prior art, troublesome detection on the suction force of the diaphragm vacuum pump by a tool is not needed, time and labor are saved, practicability is high, detection can be automatically performed every time the diaphragm vacuum pump is started, so that related workers can timely find out the fault of insufficient suction force of the vacuum pump, further expansion of the fault can be effectively prevented, and the practicability is further improved.
Description
technical field [0001] The invention relates to the technical field of pipe joints, in particular to a pipe joint for a diaphragm vacuum pump with suction self-testing function. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. [0003] Diaphragm vacuum pump is a kind of vacuum pump. It has advanced design, high working efficiency and long service life. It is a replacement product integrating high technology. After the diaphragm vacuum pump is used for a period of time, it is easy to cause the suction to weaken due to the damage of the diaphragm. If it is not found and dealt with in time, it will not only affect the working efficiency of the diaphragm vacuum pump, but also easily cause damage...
