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

Embodiment 1
[0042] see Figure 1-10 , a pipe joint for a diaphragm vacuum pump with suction self-test function, including a detection and adjustment pipe 101, the two ends of the detection and adjustment pipe 101 are respectively connected with a pump connecting pipe 102 and a pipe quick joint 103, and the inner wall of the detection and adjustment pipe 101 is fixedly connected There is a blocking adjusting ring 104, the inner side of the blocking adjusting ring 104 is provided with a matching blocking ring piston head 105, the blocking ring piston head 105 is slidingly and sealingly connected with the blocking adjusting ring 104, and the upper and lower sides of the adjusting pipe 101 are detected. A support plate 106 is fixedly connected to the inner wall of the pump. The support plate 106 is arranged on the side of the plug ring piston head 105 away from the pipe quick connector 103, and the side of the support plate 106 away from the pump connecting pipe 102 is fixedly connected with a...

The invention discloses a pipe joint for a diaphragm vacuum pump with a suction self-inspection function, which belongs to the technical field of pipe joints. The pipe joint in the invention has a suction self-inspection function. Whenever the diaphragm vacuum pump is started, the diaphragm vacuum pump can be automatically checked. The suction is tested. If the staff can observe the reflection of the suction elastic film, it means that the suction of the diaphragm vacuum pump is insufficient. On the contrary, if the suction of the diaphragm vacuum pump is normal, the plugging piston head will be separated from the blocking adjustment ring under the suction of the vacuum pump, so that the detection The regulating tube is turned on, so that the diaphragm vacuum pump can operate normally. Compared with the prior art, there is no need to use tools to check the suction of the diaphragm vacuum pump, which saves time and effort, and has strong practicability. It will automatically detect, so that the relevant staff can find out the failure of the insufficient suction of the vacuum pump in time, so as to effectively prevent the further expansion of the failure and further improve the practicability.
Description
technical field [0001] The invention relates to the technical field of pipe joints, and more particularly, to a pipe joint for diaphragm vacuum pumps with suction self-checking function. Background technique [0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space. [0003] Diaphragm vacuum pump is a kind of vacuum pump with advanced design, high working efficiency and long service life. It is a replacement product integrating high and new technology. After a period of use of the diaphragm vacuum pump, the suction force is easily weakened due to the damage of the diaphragm and other reasons. If it is not detected and dealt with in time, it will not only affect the working efficiency of the diaphragm vacuum pump, but also easily...
