Description

Technical Field

[0002] Sometimes, due to the large size of the object or the particularity of the measurement target, some indicators of many liquids or gases cannot be measured directly, because we cannot screen out all the objects. At this time, we must use special equipment to measure the indicators we need, and these tools often cleverly use some indirect measurement methods, and remote pressure gauges are one of them. Remote pressure gauges are suitable for measuring the pressure of liquids, steam, gas and other media that do not corrode steel and copper alloys. The measured value can be transmitted to the secondary instrument far away from the measurement point in the form of electrical value to achieve centralized detection and remote control.

[0003] When the existing remote pressure gauge is in use, the protection performance of the shell for the remote pressure gauge is poor. If the remote pressure gauge has an overpressure situation and is not solved in time, it is very likely to cause the remote pressure gauge to break or explode, causing internal parts to fly out and cause personal injury. Therefore, we have proposed a new solution to the safety issues of the existing remote pressure gauge, which is committed to solving the above-mentioned problems. Summary of the invention

[0025] A remote pressure gauge of the present invention comprises a pressure gauge body 1, a Hirschmann junction box 4, a pressure sensor 6, an integrated module 7, a movement 8 and a spring tube 9. The inner cavity of the pressure gauge body 1 is provided with a dial 15, a tempered glass 18 and a cover 2 in sequence from the inside to the outside. The cover 2 is movably connected to the pressure gauge body 1, and a sealing ring 19 is fixedly connected to the position where the cover 2 is movably connected to the pressure gauge body 1. The tempered glass 18 is fixedly connected between the dial 15 and the cover 2. The size of the index on the dial 15 gradually increases in a clockwise direction. A first touch sheet 14 is fixedly connected to the upper right corner of the front face of the dial 15, and a second touch sheet 141 is fixedly connected to the right and lower position of the front face of the dial 15. A pointer 3 is rotatably connected to the main body of the movement 8, and the pointer 3 is located on the front face of the dial 15. A power supply 11 is fixedly connected to the left side of the outer frame of the pressure gauge body 1, and an indicator light 10 is fixedly connected to the top of the outer frame of the pressure gauge body 1. A first speaker 12 is fixedly connected to the left side of the upper end surface of the box 4, a second speaker 13 is fixedly connected to the right side of the upper end surface of the Hirschman junction box 4, a connector 5 is fixedly connected to the bottom of the outer frame of the pressure gauge body 1, and a connecting pipe 16 is fixedly connected to the bottom of the connector 5. The first speaker 12 is a "WTN5M01 voice speaker", and the second speaker 13 is a "9--FS77N08A2 speaker". Through the above-mentioned structural design, the design scheme can have the advantages of simple structure, easy use, and good early warning effect. When in use, it can effectively improve the safety of the remote pressure gauge and provide protection for the personal safety of the staff. When the remote pressure gauge has abnormal overpressure, the pointer 3 can be effectively electrically connected to the indicator light 10 and the two speakers, so as to timely remind the staff that the remote pressure gauge has overpressure, that is, it can greatly reduce the situation where the remote pressure gauge is broken or exploded, causing the internal parts to fly out.

[0026] The Hirschmann junction box 4 is fixedly mounted on the right side of the pressure gauge body 1, the pressure sensor 6 is fixedly mounted on the upper left of the inner cavity of the pressure gauge body 1, the integrated module 7 is fixedly mounted on the top position of the inner cavity of the pressure gauge body 1, the movement 8 is fixedly mounted on the middle position of the inner cavity of the pressure gauge body 1, and the spring tube 9 is fixedly connected to the outside of the movement 8 in a "C" shape in the inner cavity of the pressure gauge body 1. The emergence of this design can effectively enable the remote pressure gauge to have the advantages of two relatively independent measurement systems, and comprehensively improved safety, reliability and accuracy.

[0027] The upper end of the connector 5 extends to the inner cavity of the pressure gauge body 1, one end of the spring tube 9 is fixedly connected to the connector 5, the pressure sensor 6 is fixedly connected to the connector 5 through a pressure-conducting tube, the pressure sensor 6 is electrically connected to the integrated module 7, and the Hirschmann junction box 4 is electrically connected to the integrated module 7.

[0028] The sharper end on the left side of the pointer 3 is a metal conductor, and the wider end on the right side is made of plastic. A wire is fixedly connected to the inner cavity of the pointer 3, and one end of the wire is fixedly connected to the sharper end on the left side of the pointer 3, and the other end of the wire is electrically connected to the power supply 11. The emergence of this design can effectively contact the first touch sheet 14 or the second touch sheet 141 through the pointer 3, thereby starting the first speaker 12 and the second speaker 13.

[0029] The first touch sheet 14 and the second touch sheet 141 are both electrically connected to the indicator light 10 through wires, the first touch sheet 14 is electrically connected to the first speaker 12 through wires, and the second touch sheet 141 is electrically connected to the second speaker 13 through wires. The first speaker 12 and the second speaker 13 broadcast different sounds.

[0030] The first touch sheet 14 and the second touch sheet 141 are both arc-shaped metal conductors, and when the pointer 3 rotates clockwise to the left side of the first touch sheet 14 and the second touch sheet 141 and fits with each other, the tip of the pointer 3 is electrically connected to the first touch sheet 14 and the second touch sheet 141.

[0031] Both ends of the rod surface of the connecting tube 16 are engraved with threads, and the threads at the upper end of the rod surface of the connecting tube 16 are threadedly connected to a movable sleeve 17, and the cylinder surface of the movable sleeve 17 is also engraved with threads. The emergence of this design can effectively enable the remote pressure gauge to be connected to two connection points in the outside world, so that the remote pressure gauge has a certain applicability and solves the problem that the original remote pressure gauge can only be connected at a single point.

[0032] When using the present invention, the staff needs to install the pressure gauge body 1 to the relevant detection point (during installation, the staff can choose whether to screw the movable sleeve 17 to the lower end of the connecting tube 16 rod body according to the actual situation. The function of the movable sleeve 17 is to adapt to the connection point that is larger than the connecting tube 16 rod body). When the pressure gauge body 1 starts to work and the pressure is too high, the pointer 3 will rotate in the clockwise direction. When the pointer 3 rotates to the position of the first touch sheet 14 and contacts each other (the first critical point), the pointer 3 quickly transmits the current in the power supply 11 to the current receiving port of the indicator light 10 through the more pointed metal conductor and wire. When the indicator light 10 is powered on, the indicator light 10 lights up, and the first touch sheet 14 transmits current to the wiring terminal on the first speaker 12. When the first speaker 12 is energized, the first speaker 12 starts to make a sound. When the staff hears the sound emitted by the first speaker 12, they can effectively and quickly get in place by observing the position of the indicator light 10, thereby eliminating the safety hazard (the staff can judge whether the first touch-sensitive sheet 14 is a critical point according to the actual situation. If not, it is considered that the pressure gauge body 1 can continue to work, and it can be temporarily ignored; and when the pointer 3 rotates to the second touch-sensitive sheet 141, the second speaker 13 starts to play a sound, and the staff needs to take relevant measures to avoid overpressure in the pressure gauge body 1 and cause accidents).

[0033] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
