Embodiment 1

[0020] exist figure 1 and figure 2 In the three-dimensional schematic diagram of the installation method of the non-pressure relief sensor shown in the figure, the valve seat 2 is fixed on the pipeline 1 by welding on one side of the pipeline 1, and the welding seam at the contact part between the peripheral edge 3 of the bottom of the valve seat 2 and the pipeline 1 It is in a sealed state; the middle part of the valve seat 2 is through-type hollow, and the valve seat tube 4 protruding out of the valve seat 2 has internal and external spiral thread openings and is integrated with the valve seat 2, and there is a spiral thread opening in the tube; the valve seat 2 tube The outside is a spiral thick wire port; the outer spiral sleeve of the valve seat tube 4 is connected with the lower end tubular joint of the ball valve type valve 5, and the 6-type connection is sealed with a sealing tape. Corresponding to the pipe size; the upper end of the ball valve type valve 5 has a val...

Embodiment 2

[0028] exist figure 1 and figure 2 In the three-dimensional schematic diagram of the installation method of the non-pressure relief sensor shown in the figure, other implementations are basically the same as Example 1, only two points are different from Example 1. One is that the connection between the valve seat 2 and the pipeline 1 is closed. The valve seat 2 is fixed on the pipeline, and the contact part between the bottom edge 3 of the valve seat 2 and the pipeline is sealed with a sealing pad; The bar can be stirred with both hands to make the hole opener 8 rotate on the pipe 1 wall to make a hole.

Abstract

The invention relates to an installation method of a sensor free from pressure release, which is characterized in that a valve seat is welded at a pipeline, and one end embedded with a hole opener is screwed into the valve top tube in a revolving way; when the end reaches the valve, the valve is opened; a screw thread long rod provided with the hole opener is screwed into a position close to a pipeline wall; when an electric portable drill is turned on to drill through the pipeline wall and the hole opener is retreated to the outside of the valve, the valve is closed; the hole opener continues to be retreated until the hole opener is dismantled; a metal conduit embedded with a sensor probe is screwed into the valve top tube in a revolving way; when the metal conduit reaches the valve, the valve is opened; the probe provided with the sensor passes the valve, enters the pipeline and contacts with medium; a sealing screw cap on the metal conduit is screwed down in a revolving way and leans against the valve top tube to be fixed; 500-2000 thin screw threads are respectively arranged inside the valve top tube, outside the metal conduit and the screw thread long rod, and resistance of 500-2000 screw threads is generated on the medium which enters the pipeline by pressure after the valve is opened; as a result, the medium inside the pipeline is blocked without affecting installation of the sensor.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a method for installing a pressure relief-free sensor. Background technique [0002] In order to measure or perform quality inspection of the medium flowing in the pipeline, the sensor technology needs to be installed on the pipeline or container of the medium. During installation, the production must be stopped, and the medium in the pipeline must be emptied, and then the pipeline is drilled and installed. The sensor probe has achieved the purpose of measuring the medium in the pipeline or performing quality inspection, so that the installation will not only delay production, but also cause certain economic losses. If the sensor probe needs to be repaired or replaced, the production must also be stopped and the medium in the pipeline must be emptied, and then the probe must be removed for replacement and maintenance. The method of installing sensors will also affect production and cause ...
