[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] For easier understanding, see Figure 1-3 , an intelligent gas relay device provided in an embodiment of the present application includes a relay body 1;

[0042] The upper end surface of the relay body 1 is provided with a pressure monitoring working area and a signal wiring area;

[0045] The oil inlet 2 and the oil outlet 3 are both connected to the inner cavity of the relay body 1 .

[0046] In the embodiment of the present application, an oil inlet 2 and an oil outlet 3 are respectively provided on the left and right sides of the relay body 1, a visual window 13 is provided at the front end of the relay body 1, and an inserted liquid level gauge 12 is provided in the visual window 13. The improved inserted liquid level gauge 12 improves the pressure resistance of the float 15 compared with the existing float 15, and can be more suitable for different environments. The upper end surface of the relay body 1 is provided with a pressure monitoring working area and a signal wiring area. In addition to retaining the function of the original gas relay, a pressure transmitter 6 is added to the pressure monitoring working area; when the gas in the gas relay is accompanied by a sudden increase in pressure, the rising pressure wave acts on the pressure transmitter 6, and an alarm is given in time.

[0047] See also Figure 1 As shown, the pressure monitoring work area is provided with an air release valve 4, an oil release nozzle 5 and a pressure transmitter 6.

[0048] The signal wiring area is provided with a hydrogen sensor connector 7, an ultrasonic sensor connector 8, an acetylene sensor connector 9, a light gas signal connector 10 and a heavy gas signal connector 11.

[0049] In the embodiment of the present application, a pressure monitoring working area and a signal wiring area are arranged on the left and right sides of the upper end surface of the relay body 1; a vent valve 4, an oil drain nozzle 5 and a pressure transmitter 6 are arranged in the left pressure monitoring working area, and a hydrogen sensor connector 7, an ultrasonic sensor connector 8, an acetylene sensor connector 9, a light gas signal connector 10 and a heavy gas signal connector 11 are arranged in the right signal wiring area.

[0050] It is worth mentioning that in order to increase the usability of the relay body 1 , covers may be provided on the pressure monitoring work area, the signal wiring area and the visual window 13 .

[0051] See also Figure 1 and Figure 2 As shown, the insertion type liquid level gauge 12 includes a mounting table 18, a first tube body 14 and a float 15;

[0052] The first tube body 14 is fixed to the upper end of the relay body 1 through the mounting table 18;

[0053] The first tube body 14 is a hollow cavity structure, and a liquid discharge port 19 is disposed at the lower end of the first tube body 14 .

[0054] The insertion type liquid level meter 12 further includes a sensing element 16;

[0055] The induction element 16 is disposed on one side of the first tube body 14;

[0056] At least two floats 15 are disposed in the first tube body 14 , and the float 15 at the upper end of the first tube body 14 is provided with an induction ring 20 for the induction member 16 .

[0057] The insertion level gauge 12 further includes a side pipe 17;

[0058] The side pipe 17 is arranged on the other side of the first pipe body 14;

[0059] The side pipe 17 is disposed obliquely upward, and an interface of the side pipe 17 is disposed at a position close to the installation table 18 .

[0060] In the embodiment of the present application, the insertion level gauge 12 includes a mounting table 18, a first tube body 14, a float 15, a sensor 16 and a side tube 17; the upper end of the first tube body 14 is fixed to the upper end of the relay body 1 through the mounting table 18, the first tube body 14 is an internal hollow cavity structure, and a drain port 19 is provided at the lower end of the first tube body 14.

[0061] At least two floats 15 are arranged in the first tube body 14, and an induction ring 20 for the induction element 16 is arranged in the upper float 15; the induction element 16 and the side pipe 17 are arranged on the left and right sides of the first tube body 14 respectively; the side pipe 17 is arranged upwardly in an inclined manner, and the interface of the side pipe 17 is located at a higher position. When the fluid flows into the first tube body 14 from the side pipe 17, the inclined arrangement of the side pipe 17 can make the fluid exert a downward impact force on the float 15, which can prevent the float 15 from getting stuck.

[0062] Furthermore, the float 15 of the utility model is connected in series along the axis direction of the first tube 14 to form a float string, and the floats are not connected to each other, which improves the pressure resistance of the float 15 compared with the existing float 15 and can be more suitable for different environments. The float 15 of the utility model is an inflatable float filled with pressure-resistant gas, which is more conducive to improving the pressure resistance of the float.

[0063] It should be noted that the utility model improves the insertion type liquid level gauge 12, and the float 15 is connected in series along the axial direction of the tube body to form a float string, which improves the pressure resistance of the float 15 compared with the existing float 15 and can be more suitable for different environments; the side pipe 17 is inclined so that the fluid can exert a downward impact force on the float 15, which can prevent the float 15 from getting stuck.

[0064] The mounting table 18 is located at the top of the relay body 1 . Compared with the method of installing the liquid level gauge on the side of the relay body 1 , this structure of the liquid level gauge is less likely to cause deformation of the insertion type liquid level gauge 12 .

[0065] Furthermore, the induction ring 20 is located at the center line of the float 15, and the axis of the induction ring 20 is colinear with the axis of the float 15, so as to ensure that the magnetic field strength in the circumferential direction is evenly distributed.

[0066] The float 15 rises and falls with the change of the liquid level, so that the induction ring 20 in the upper end of the float 15 rises and falls with the change of the liquid level, and the induction ring 20 is used for the induction member 16 to realize the liquid level signal transmission.

[0067] See also Figure 1 and Figure 3 As shown, the pressure transmitter 6 includes a second tube body 21, an inlet 22, an outlet 23 and a pressure sensing assembly;

[0068] The second tube body 21 is provided with an inlet 22 and an outlet 23;

[0069] The second tube body 21 is connected to the pressure sensing assembly via a fixing seat 24 .

[0070] The pressure sensing component includes a sensing core 25, a conducting member 26 and an alarm member 27;

[0071] The upper end of the second tube body 21 is provided with an alarm component 27, a conductive component 26 and a sensing core 25 from top to bottom through a fixing seat 24;

[0072] The conductive member 26 is disposed between the alarm member 27 and the inductive core 25 .

[0073] The upper end of the second tube body 21 is provided with a core mounting hole;

[0074] The fixing seat 24 is connected with the second tube body 21 through the core body mounting hole;

[0075] The outer side of the fixing seat 24 is sealed with the outer wall of the second tube body 21;

[0076] The outer wall of the induction core 25 is sealed with the fixing seat 24 via a sealing ring.

[0077] In the embodiment of the present application, the pressure transmitter 6 includes a second tube body 21, an inlet 22, an outlet 23, a fixing seat 24, a sensing core 25, a conductive member 26 and an alarm member 27; the second tube body 21 is provided with an inlet 22 and an outlet 23 on the left and right sides, and the upper end of the second tube body 21 is provided with an alarm member 27, a conductive member 26 and a sensing core 25 from top to bottom through the fixing seat 24, and the conductive member 26 is connected between the alarm member 27 and the sensing core 25.

[0078] Specifically, the upper end of the second tube body 21 is provided with a core mounting hole, the fixing seat 24 is connected to the second tube body 21 through the core mounting hole, and the outer side of the fixing seat 24 is sealed with the outer wall of the second tube body 21. The outer wall of the induction core 25 is sealed with the fixing seat 24 through a sealing ring.

[0079] During the working process of the utility model, the alarm part 27 on the upper part of the pressure transmitter 6 is on the upper end surface of the relay body 1, and the inlet 22 is inside the relay body 1. When the gas enters from the inlet 22, the pressure pushes the induction core 25 to move radially, and the pressure is transmitted to the alarm part 27 through the transmission part 26 to complete the pressure collection and alarm.

[0080] It should be noted that the gas relay of the present invention not only retains the functions of the original gas relay, but also adds a pressure transmitter 6; when the gas pressure in the gas relay suddenly rises, the rising pressure wave acts on the pressure transmitter 6, giving a timely alarm.

[0081] The gas relay of the utility model has reliable action, high conduction accuracy, long service life and is not prone to malfunction when the mechanism is in operation.
