Technical Field
[0001] The utility model belongs to the technical field of gas transmission, and particularly relates to a plugging device before a diaphragm meter. Background Art
[0002] A diaphragm meter is generally connected to a gas pipeline during gas transmission to measure the used gas. Currently, non-residential gas users may face the situation of stopping using gas during gas use. When non-residential gas users do not use gas, it is necessary to plug the diaphragm meter so that gas can no longer enter the user's home.
[0003] However, there are some problems in the existing technology: the existing diaphragm meters usually use screw threads to connect the pipelines. The pipelines connected by screw threads are usually plugged after the meter or the meter is removed for plugging. Plugging after removing the meter is more suitable for users who have been out of use for a long time and apply for gas cut-off and account cancellation, but it is not friendly to merchants who temporarily stop using gas for decoration and renovation. Removing the meter may cause damage and air leakage of the meter, and the later maintenance is difficult and the construction cost is high. Therefore, we propose a plugging device before a diaphragm meter. Content of the Utility Model
[0004] Aiming at the problems existing in the existing technology, the purpose of the utility model is to provide a plugging device before a diaphragm meter. Through a detachable gasket, the plugging of the diaphragm meter can be completed without removing the meter, thus avoiding the situation that the meter may be damaged during the removal of the meter.
[0005] The utility model is realized as follows. A plugging device before a diaphragm meter includes a diaphragm meter housing. An exhaust hole is opened at the upper end of the diaphragm meter housing. A exhaust pipe is fixedly connected above the exhaust hole. A sleeve is detachably connected to the exhaust pipe.

[0021] To further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings as follows.
[0022] As Figures 1 to 4 shown, a plugging device added in front of a diaphragm meter provided by an embodiment of the present utility model includes a diaphragm meter housing 1. The diaphragm meter housing 1 is rectangular and made of stainless steel. A meter is arranged inside the diaphragm meter housing 1 to detect the passing amount of gas, and a display screen is arranged on the surface of the diaphragm meter housing 1 to display the value of the gas passing amount.
[0023] An exhaust hole is opened at the upper end of the diaphragm meter housing 1, and an exhaust pipe 2 is fixedly connected above the exhaust hole. The exhaust pipe 2 is made of stainless steel. The main function of the exhaust pipe 2 is to discharge the gas metered by the diaphragm meter from the diaphragm meter. The upper end of the exhaust pipe 2 is detachably connected with a sleeve 3. The sleeve 3 is divided into upper and lower parts. Both upper and lower parts of the sleeve 3 are cylindrical, and the upper and lower parts of the sleeve 3 are fixedly connected. The sleeve 3 is made of stainless steel. The main function of the sleeve 3 is to connect the gas pipe 4 and the exhaust pipe 2 so that the gas can enter the homes of residential users for use.
[0024] Threads are arranged on the outer wall of the upper end of the exhaust pipe 2, and threads corresponding to the threads of the exhaust pipe 2 are arranged on the inner wall of the lower end of the sleeve 3. The exhaust pipe 2 and the sleeve 3 are connected by threads. Using threaded connection is convenient for removing the diaphragm meter for repair or replacement when the diaphragm meter is damaged, and is also convenient for installing a gasket 5 to plug the diaphragm meter.
[0025] A gas pipe 4 is detachably connected to the upper end of the sleeve 3. Threads are arranged on the outer wall of the upper end of the sleeve 3, and a joint 8 is fixedly connected to one end of the gas pipe 4. Threads corresponding to the threads of the sleeve 3 are arranged on the inner wall of the joint 8. The gas pipe 4 is connected to the sleeve 3 by threads through the joint 8. Using threaded connection is convenient for installing and disassembling the gas pipe 4.
[0026] A gasket 5 is detachably connected inside the sleeve 3. The gasket 5 is arranged at the connection of the upper and lower parts of the sleeve 3. The gasket 5 is located above the exhaust pipe 2. The shape and size of the gasket 5 are the same as the cavity inside the sleeve 3. Slots are opened at both ends of the gasket 5. Grooves are opened on the inner wall of the sleeve 3. A spring 9 is fixedly connected to the inner wall of the groove. A clamping block 10 is fixedly connected to the spring 9, and the clamping block 10 is clamped in the slot of the gasket 5. A handle 11 is fixedly connected to the bottom end of the gasket 5.
[0027] Put the gasket 5 into the sleeve 3 through the handle 11, and then press down the gasket 5. The clamping block 10 is forced to contract into the groove of the sleeve 3, so that the spring 9 is forced to compress. Then rotate the gasket 5 through the handle 11 so that the clamping block 10 is clamped in the slot of the gasket 5, thereby fixing the gasket 5.
[0028] A theft-proof buckle 6 is sleeved outside the sleeve 3. The theft-proof buckle 6 includes a first buckle 601 and a second buckle 602. Both ends of the first buckle 601 are fixedly connected with clamping posts 603. Slots are formed at both ends of the second buckle 602. The clamping posts 603 are clamped in the slots. The first buckle 601 and the second buckle 602 are detachably connected through the clamping posts 603.
[0029] After the gasket 5 is arranged in the sleeve 3, the first buckle 601 and the second buckle 602 are respectively placed on both sides of the sleeve 3. Then, the first buckle 601 and the second buckle 602 are pressed so that the clamping posts 603 on the first buckle 601 are clamped in the slots of the second buckle 602, thereby forming the theft-proof buckle 6 and making the sleeve 3 non-detachable.
[0030] A lead seal 7 is arranged on the theft-proof buckle 6. Through holes are formed in both the first buckle 601 and the second buckle 602. The lead seal 7 is arranged through the through holes. The main function of the lead seal 7 is to prevent malicious damage and prevent others from stealing gas for use.
[0031] The working principle of the present utility model is as follows: When the non-residential gas user does not use gas to block the diaphragm meter, first unscrew the sleeve 3 from the exhaust pipe 2, then put the gasket 5 into the sleeve 3, and by rotating the handle 11, the clamping block 10 on the sleeve 3 is clamped in the slot on the gasket 5. Then, the sleeve 3 is screwed tightly onto the exhaust pipe 2 again. Then, the first buckle 601 and the second buckle 602 are placed at both ends of the sleeve 3, and the first buckle 601 and the second buckle 602 are pressed firmly. The clamping posts 603 on the first buckle 601 are clamped in the slots of the second buckle 602, thereby being fixedly connected to the sleeve 3. Then, the lead seal 7 is arranged in the through holes on the first buckle 601 and the second buckle 602 to complete the blocking of the diaphragm meter.
[0032] When the non-residential gas user uses gas, the lead seal 7 and the theft-proof buckle 6 are removed, then the sleeve 3 is unscrewed, and then the gasket 5 is taken out to supply gas to the user again.
[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
