Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1-4, the utility model discloses a pneumatic valve position display sensor, which comprises a housing 1, wherein a pressing component, an elastic unit and a supporting component are arranged in the housing 1. The pressing component comprises a mandril 2 and an adjusting nut 3, the elastic unit is a spring 5, and the supporting component comprises an adjusting pipe and an adjusting rod.

The adjusting seat is arranged in the shell 1, and the adjusting seat 7 is of a through structure. One end of the adjusting seat 7 is connected with a pressure reducing valve 8 through a flange, and the model of the pressure reducing valve 8 is QTY-08. And the other end of the adjusting seat 7 is connected with the adjusting tube 6 through threads, and one end of the adjusting tube 6 departing from the adjusting seat 7 extends out of the shell 1. An external thread is arranged on the outer pipe wall of one end of the adjusting pipe 6, which is far away from the adjusting base 7, and two fixing nuts 4 are screwed on the external thread. The two fixing nuts 4 are respectively positioned at the inner side and the outer side of the shell 1, and when the two fixing nuts 4 clamp the inner side surface and the outer side surface of the shell 1, the adjusting pipe 6 is fixed. In actual installation, only the fixing nut 4 on the outer side of the shell 1 needs to be screwed, the operation is simple, and the design does not need to additionally arrange a shaft shoulder on the adjusting pipe 6, so that the advantages of light weight and low cost are achieved.

A fixed rod and a spring 5 are arranged in the adjusting pipe 6. The fixed rod is in a stepped shaft structure and is coaxially arranged with the adjusting pipe 6. One end of the adjusting pipe 6 departing from the adjusting seat 7 is provided with an end wall, a through hole is formed in the center of the end wall, the small-diameter section of the fixed rod extends out of the through hole, and the large-diameter section of the fixed rod abuts against the end wall. Similarly, an adjusting nut 3 is connected to the large-diameter section of the fixed rod and the end of the fixed rod, which is far away from the adjusting seat 7, through threads.

The spring 5 is sleeved outside the large-diameter section of the fixed rod, one end of the spring 5 abuts against the adjusting nut 3, and the other end of the spring 5 penetrates through the adjusting seat 7 and abuts against a diaphragm on the pressure reducing valve 8. The tightness of the spring 5 in the initial state can be adjusted by adjusting the nut 3.

And the air outlet of the pressure reducing valve 8 is connected with a pressure gauge through a long pipe, and the pressure gauge and the long pipe are not specifically shown in the drawing. The model number of the pressure gauge is Y100. The value and unit displayed on the pressure gauge are adjusted to 0-50 mm. The length of the long tube is selected to be more than 20 meters, so that the function of remote watching can be realized. When the position of the mandril 2 changes, the elastic force of the spring 5 can be directly influenced, and when the pressure reducing valve 8 is used for testing, the elastic unit in the pressure reducing valve 8 can be balanced with the elastic force of the spring 5, so that the variation of the position of the mandril 2 can be measured through the pressure gauge. When the hydraulic throttle valve is used specifically, the shell 1 is fixed, the hydraulic throttle valve core is connected with one end of the ejector rod 2 extending out of the shell 1, the valve core and the ejector rod 2 are coaxially arranged, when the position of the hydraulic throttle valve core changes, the ejector rod 2 can be driven to change, finally, the specific position of the hydraulic throttle valve core can be read out through the pressure gauge under the condition of no electricity, and the operation safety of an oil well site is ensured.
