Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figures 1 to 4, the pressure pulsation sensor connector includes a connecting pipe 3 and an adapter 2, wherein the connecting pipe 3 is used to communicate with the pipeline of the system under test, the adapter is installed on the connecting pipe, and the adapter 2 is used for For installation of pressure pulsation sensor. The pressure pulsation sensor can be quickly fixed to the system pipeline under test, avoiding pipeline perforation, liquid leakage and realizing the function of protecting the sensor.

The connecting pipe 3 includes a channel I31 for communicating with the pipeline of the system under test and a channel II32 for installing the adapter, the channel I31 and the channel II32 are connected, the channel I is a horizontal channel, and the channel II is a vertical channel; One end of the channel I of the pipe is provided with an external thread for connecting with the internal thread of the pipeline under test; the other end of the channel I of the connecting pipe is provided with an internal thread for connecting with the external thread of the pipeline of the system under test. The pipe connection of the measuring system is simple.

Channel II 32 is provided with an internal thread that matches the external thread of the adapter, and the adapter 2 only needs to be screwed on the connecting pipe, which is easy to install. Channel II is matched with the inner end of the adapter through a sealing slope, that is, the end surface of the adapter is provided with a sealing slope I22, and the channel II is provided with a sealing slope II34 matching the sealing slope I, so as to realize the connection and sealing between the adapter and the connecting pipe.

The adapter 2 is provided with a sensor installation hole 21, the sensor installation hole 21 is an internal threaded hole adapted to the external thread of the pressure pulsation sensor, and a sealing ring is provided between the pressure pulsation sensor 1 and the sensor installation hole for sealing.

The pipe body of the connecting pipe 3 is provided with an exhaust passage 33 connected with the passage II, and the exhaust passage is also connected with the passage I. The exhaust passage 33 is provided with an exhaust bolt 4, which is convenient for clearing the residual gas in the pipeline and protecting sensor.

The working principle is:

The first step is to install the pressure pulsation sensor into the adapter, the adapter into the channel II of the connecting pipe, and the exhaust bolt into the exhaust channel; there are sealing slopes on the channel II and the adapter to ensure good contact;

The second step is to disconnect the pipeline of the system under test from the existing connection of the pipeline, drain the liquid in spite of the pipeline, and then connect the front end of the connecting pipe with the internal thread of the pipeline under test, and connect the rear end with the external thread of the pipeline under test ;

In the third step, liquid is injected into the pipeline of the system under test, and the pipeline is pressurized to ensure that there is no leakage at the pipeline connection;

The fourth step is to slowly loosen the exhaust bolt, and the liquid-gas mixture will be discharged through the exhaust channel until only the liquid is discharged, which means that the residual gas in the pipeline of the system under test has been exhausted, and the exhaust bolt should be tightened;

The fifth step is to complete the pressure pulsation test of the pipeline liquid of the system under test.
