[0055] Example 2

[0056] Reference Figures 3 to 7 and Fig.11This embodiment is different from the first embodiment in that: the transmission part 201 includes a mounting cover 201a sleeved on the outer surface of the connecting pipe 100, and a partition 201b fixedly arranged in the mounting cover 201a, and the mounting cover 201a is located at the edge of the end closest to the connecting pipe 100; thirty-six partitions 201b are arranged, and the thirty-six partitions 201b are distributed in a ring shape on the front side of the gap between the end of the connecting pipe 100 and the connecting pipe 2 101 (note: the direction close to the connecting pipe 2 101 is the front, and the opposite direction is the rear, and the same applies to the following text), and a transmission area 201c is formed between every two adjacent partitions 201b, the bottom surface of the partition 201b is in contact with the outer surface of the connecting pipe 2 101, and the back of the partition 201b is in contact with the end face of the connecting pipe 1 100.

[0057] The transmission area 201c includes a mounting block 201d fixedly arranged between two adjacent partitions 201b, and a movable part 201f arranged on the mounting block 201d; a transmission cavity 201e is formed between the bottom surface of the mounting block 201d and the outer surface of the connecting pipe 101. There are thirty-six partitions 201b and therefore thirty-six transmission cavities 201e. The transmission cavity 201e is located in front of the gap between the connecting pipe 100 and the connecting pipe 101. The left and right sides of the transmission cavity 201e are blocked by the partition 201b. The transmission cavity 201e enables the gas leaking from the gap to blow the movable part 201f at the corresponding position. The thirty-six transmission areas 201c are evenly distributed. On the one hand, it can help the staff to locate the leakage area more accurately, and can also preliminarily judge the size of the leakage area by the number of the sounding knocking parts 202, and the trigger plate 201f-2 can also be more easily triggered. On the other hand, the subdivision of the transmission area 201c also improves the sensitivity of the device.

[0058] The movable part 201f includes a fixed column 201f-1 rotatably arranged at the bottom end of the mounting block 201d, a trigger plate 201f-2 fixedly arranged at the lower side of the fixed column 201f-1, and a transmission plate 201f-3 fixedly arranged at the upper side of the fixed column 201f-1; a space for the transmission plate 201f-3 to move is provided inside the mounting block 201d, the bottom end of the mounting block 201d is in close contact with the outer surface of the fixed column 201f-1, and the gas is blocked from entering and exiting the transmission chamber 201e from the bottom of the mounting block 201d, the trigger plate 201f-2 is located in the transmission chamber 201e, and the material of the movable part 201f as a whole is They are all very light; what is important is that grooves are provided at the same positions on both sides of multiple partitions 201b, and protrusions 201f-4 are fixedly provided on both sides of the bottom of multiple trigger plates 201f-2. The grooves are very shallow, and the protrusions 201f-4 are very small and hemispherical. The protrusions 201f-4 can be stuck in the grooves. The protrusions 201f-4 and the grooves are both located on the same plane and in the middle of the partition 201b, so that the trigger plates 201f-2 can be in a state perpendicular to the outer surface of the connecting tube 101 without being subjected to external forces. The trigger plate 201f-2 can be pushed by a small force and the protrusions 201f-4 can leave the grooves.

[0059] Reference Fig.11 The knocking part 202 includes a fixed block 202a fixedly arranged on the inner top surface of the mounting block 201d, a bell 202b fixedly arranged at the lower part of the fixed block 202a, a fixed rod 202c fixedly arranged between the two partitions 201b, a rotating tube 202d rotatably arranged in the middle of the fixed rod 202c, a knocking rod 202e fixedly arranged on the upper right side of the rotating tube 202d, and a knocking ball 202f fixedly arranged at one end of the knocking rod 202e. A toggle rod 202g is connected to the lower right side of the rotating tube 202d through a torsion spring, a curved plate 202h is fixedly arranged on the left side of the top of the transmission plate 201f-3, and a plurality of convex teeth 202i are fixedly arranged on the upper side of the curved plate 202h; the knocking ball 202f is an iron ball, and the bell 202b is made of iron. The knocking ball 202f can contact the bell 202b and knock the bell 202b, and the toggle rod 202g can contact the plurality of convex teeth 202i.

[0060] Every three adjacent transmission areas 201c form a transmission unit 201g, and the number of knocking parts 202 is the same as the number of transmission units 201g, that is, twelve, and each transmission unit 201g is connected to the knocking part 202; for each transmission unit 201g, a transmission rod 201h is fixedly arranged on the front side of the two transmission plates 201f-3 on both sides, and the transmission rod 201h can contact with the middle transmission plate 201f-3, and the left end of the left transmission rod 201h will not be too long to affect the movement. The right end of the component 201f passes through the partition 201b on the right side of the transmission area 201c, extends into the mounting block 201d in the middle transmission area 201c, and contacts the front side of the transmission block in the mounting block 201d. The transmission rod 201h in the transmission area 201c on the right and the transmission block in the transmission area 201c on the left are symmetrical with each other and have the same design principle. The partition 201b through which the two transmission rods 201h pass and the middle mounting block 201d both provide movement space for the two transmission rods 201h.

[0061] Reference Figure 6 and Fig.11, gas leaks from the gap between the connecting pipe 100 and the connecting pipe 2 101 corresponding to the middle transmission chamber 201e, and the gas enters the transmission chamber 201e forward, blowing the trigger plate 201f-2 to rotate forward, and drives the transmission plate 201f-3 to rotate backward through the fixed column 201f-1, so that the arc plate 202h202h and the convex teeth 202i202i at the top of the transmission plate 201f-3201f-3 rotate backward, and the convex teeth 202i The tip of the toggle rod 202g abuts against the toggle rod 202g, and the tip of the convex tooth 202i drives the toggle rod 202g to rotate upward, and the toggle rod 202g drives the rotating tube 202d, the knocking rod 202e and the knocking ball 202f to rotate synchronously, and the knocking ball 202f leaves the surface of the bell 202b. When the arc-shaped rod and the convex tooth 202i continue to rotate, the toggle rod 202g is not pushed by the convex tooth 202i, and the toggle rod 202g falls into the recess between the two convex teeth 202i, and the toggle rod 202g rotates downward, driving the rotating tube 202d, the knocking rod 202e and the knocking ball 202f to move synchronously, the knocking ball 202f knocks the bell 202b, and then enters the next repeated movement unit, the knocking ball 202f knocks the bell 202b multiple times until the convex tooth 202i leaves the toggle rod 202g, when the transmission plate 201f-3 drives the arc plate 202h and the convex tooth 202i to rotate, because the toggle rod 202g and the rotating tube 202d Through the torsion spring connection, the toggle rod 202g can be pushed to the left a short distance and can rebound under the action of the torsion spring, so the toggle rod 202g will not block the rotation of the convex tooth 202i and the arc rod; when the leakage at the leaking point is intermittent, the trigger plate 201f-2201f-2 can reciprocate, which can drive the arc plate 202h and the convex tooth 202i to reciprocate, repeating multiple motion cycles, and the bell 202b can make sounds repeatedly.

[0062] The transmission rods 201h on both sides will not affect the backward rotation of the middle transmission plate 201f-3 itself; when gas leakage occurs in the gap corresponding to any transmission area 201c on the left and right sides, the gas blows the trigger plate 201f-2 at the corresponding position forward, thereby driving the transmission plate 201f-3 and the transmission rod 201h to rotate backward, and the transmission rods 201h on both sides can drive the transmission rod 201h in the middle transmission area 201c to rotate backward, connecting the knocking part 202; this arrangement reduces the number of knocking parts 202, reduces costs, and reduces installation procedures, but does not reduce the distribution density of the transmission area 201c, and gas leaks at the positions corresponding to the thirty-six transmission areas 201c can trigger an alarm.

[0063] The fixing part 203 includes a mounting ring 203a fixedly arranged on the rear side of the mounting cover 201a, three sealing grooves 203b provided on the inner surface of the mounting ring 203a, and three sealing rings 203c respectively sleeved in the three sealing grooves 203b, a spring sheet 203d arranged on the mounting ring 203a, and a fastener 203e threadedly connected to the spring sheet 203d. The mounting ring 203a is sleeved on the outer surface of the connecting pipe 100, and the fastener 203e is threadedly connected to the mounting ring 203a. The spring sheet 203d is fixedly mounted on the surface of the mounting ring 203a through the fastener 203e. The lowest point of the lower surface of the rear part of the spring sheet 203d abuts against the outer surface of the connecting pipe 100. The fastener 203e and the fastening bolt, the fastening bolt and the spring sheet 203d cooperate as follows: According to the prior art, the contact degree between the spring sheet 203d and the outer surface of the connecting pipe 100 can be adjusted by loosening and tightening the fastener 203e. The closer the fastener 203e is screwed, the closer the spring sheet 203d contacts the connecting pipe 100. The setting of the sealing ring 203c can prevent gas from entering and exiting the mounting cover 201a from the mounting ring 203a. The spring sheet 203d can enable the warning component 200 to clamp the connecting pipe 100, and can also fix the position of the warning component 200, so that the partition 201b is in close contact with the end face of the connecting pipe 100, and also prevent the abutment component from shifting forward and backward on the connecting pipe 100 to affect the detection effect. The sealing ring 203c can also play a certain clamping role. The spring sheet 203d and the fastener 203e are provided in two groups symmetrical up and down to clamp the connecting pipe 100.

[0064] When installing the warning component 200, first insert the three sealing rings 203c into the three sealing grooves 203b, then put the installation ring 203a on the outer periphery of the connecting pipe 100, move the fixing ring backward until the partition 201b abuts against the end surface of the connecting pipe 100, then tighten the fastener 203e, and then check whether the position of each trigger is fixed. If it is not fixed, fix it manually; when it is necessary to remove the warning component 200, unscrew the fastener 203e and pull the warning component 200 off the connecting pipe 100.

[0065] The rest of the structure is the same as that of Example 1.

[0066] In summary: when gas leakage occurs at the gap between connecting pipe 100 and connecting pipe 2 101, the bottom end of the trigger plate 201f-2 in the transmission chamber 201e at the corresponding position can be blown forward, thereby driving the corresponding transmission plate 201f-3 to rotate to the right, causing the knocking part 202 to emit repeated sound alarms to remind the staff to deal with it in time. The larger the leakage area at the gap, the more knocking parts will sound the alarm, allowing the staff to preliminarily and quickly judge the severity of the gas leakage and take corresponding measures.

[0067] Example 3

[0068] Reference Figure 1 and Figures 8 to 10 This embodiment is different from the above embodiments in that it includes any of the above gas leakage warning mechanisms, and also includes a valve body 300, a connecting pipe 100 located on the valve body 300, the connecting pipe 100 and the valve body 300 are integrated, and also includes a pre-treatment component 400; the valve body 300 is usually provided with two left and right connecting pipes 100, so there are correspondingly two connecting pipes 2 101 and two warning components 200 and two pre-treatment components 400;

[0069] The pretreatment component 400 includes a fixed cover 401 installed on the installation cover 201a, a telescopic airbag 402 arranged on the outside of the fixed cover 401, and a sliding ring 403 arranged on the front side of the telescopic airbag 402. The sliding ring 403 is slidably arranged on the connecting pipe 101. The sliding ring 403, the telescopic airbag 402, the fixed cover 401, the warning component 200 and the outer surfaces of the connecting pipes 1 100 and 101 together form a closed space. When gas leaks, it will enter the telescopic airbag 402. The airbag can expand outward and forward, driving the sliding ring 403 to slide forward to collect the leaked gas, providing time for the staff to deal with the emergency.

[0070] A protruding ring 404 is fixedly provided on the front outer side of the mounting cover 201a, and six slots 406 are opened on the rear side of the protruding ring 404. Six clamping blocks 405 are fixedly provided on the front inner side of the fixed cover 401; the clamping blocks 405 are all nested in the clamping slots 406. When installing the fixed cover 401, align the multiple clamping blocks 405 with the corresponding clamping slots 406, and the clamping blocks 405 can be nested into the clamping slots 406 by applying force to fix the position of the fixed cover 401. When the fixed cover 401 needs to be removed, the fixed cover 401 can be pulled out backwards, and then moved out of the connecting pipe 101 together with the pretreatment component 400.

[0071] An air nozzle 407 is installed on the sliding ring 403. When the air nozzle 407 is opened, the gas in the telescopic airbag 402 can be collected. Then the device can be removed and an air cavity or a balloon can be installed on the air nozzle 407 as an emergency response measure.

[0072] The rest of the structure is the same as that of Example 2.

[0073] In summary: after gas leakage, the trigger plate 201f-2 can be blown up, and after leaving the transmission cavity 201e and entering the telescopic airbag 402, the telescopic airbag 402 can collect gas to prevent gas leakage, and the telescopic airbag 402 can be telescoped and expanded and has a larger accommodating space.
