Abstract

A gas meter and pipeline locking device comprises a switch valve and a connecting pipe. The intake end of the switch valve is connected with a main pipeline. The connecting pipe comprises a bend. Two ends of the bend are both rotatably connected with nus. The nuts at two ends of the bend are used for being tightened to an external thread of the exhaust end of the switch valve and an external thread of an intake hole of a gas meter. One end, connected with the exhaust end of the switch valve, of the bend is provided with a plum-flower pipe orifice. The bore wall of the exhaust end of the switch valve is provided with a plum-flower socket matching with the plum-flower pipe orifice. The nuts are anti-removal nuts. The gas meter and pipeline locking device has the advantage that the problem that gas stealing, gas leakage and gas meter damage caused by people mounting and demounting gas meters without permission and moving the gas meters without permission can be effectively avoided.

Description

Gas meter, flow meter road locking device
Technical field:
The present invention relates to the connection member of a kind of gas meter, flow meter and air inlet pipeline, it is especially a kind of gas meter, flow meter road locking dress Put.
Background technology:
With the raising of people's living standard, many is home-use to have gone up pipe gas, enters into user house in pipe gas During front yard, typically will install switch valve and gas meter, flow meter, the inlet end of switch valve is used for being connected with main pipeline, and gas meter, flow meter passes through even Take over to be connected with the outlet side of switch valve and communicate, at present, connecting tube generally comprises bend pipe, and the two ends of bend pipe all rotatably connect There is nut, the two ends of bend pipe can be tightened on the outlet side of switch valve respectively by the internal thread on nut and the entering of gas meter, flow meter On gas end, because common nut can be dismantled by random the carrying out of general spanner, therefore, people can tear open privately, private Self installation gas meter, flow meter, thus the phenomenon stealing gas, gas leakage and gas meter, flow meter damage violating the regulations can be caused, or pulls gas meter, flow meter privately Make gas meter, flow meter run-off the straight, can stop operating after gas meter, flow meter tilts certain angle and reach the purpose of surreptitiously gas.
Content of the invention:
The technical problem to be solved in the present invention be to provide one kind can effectively prevent people's private from tearing open, private and private dynamic gas meter, flow meter And the gas meter, flow meter road locking device stealing gas, gas leakage and gas meter, flow meter damage phenomenon violating the regulations causing.
The technical solution of the present invention is to provide a kind of gas meter, flow meter road locking device with following structure: includes opening Close valve and connecting tube, the inlet end of switch valve is used for being connected with main pipeline, and connecting tube includes bend pipe, and the two ends of bend pipe are all rotatable Be connected with nut, on the external screw thread that the nut at bend pipe two ends is respectively used to be tightened on the outlet side of switch valve and the entering of gas meter, flow meter On the external screw thread of gas port, wherein, one end that bend pipe is used for being connected with the outlet side of switch valve is provided with one section of plum blossom mouth of pipe, switch valve The inner hole wall of outlet side be provided with the plum blossom connected in star matching with the plum blossom mouth of pipe, nut is cap nut of detaching proof.
Gas meter, flow meter road of the present invention locking device, wherein, cap nut of detaching proof include overcoat, inner sleeve, nut pad and Multiple reeds, overcoat is located at the outside of inner sleeve, inside puts and is provided with internal thread, one end of each reed justifies circumferentially uniform company respectively It is connected on the periphery wall of inner sleeve, the direction of the other end of each reed screws in opposite direction, overcoat with the interior internal thread putting Multiple inclined-plane boss for blocking reed are uniformly provided with internal perisporium, the inclined-plane incline direction of inclined-plane boss with interior put interior Screw thread screw that direction is identical, nut pad is located at the interior in the hole of overcoat and is located at the lower end of inner sleeve, and nut pad passes through spring Collar is connected with overcoat.
After above structure, compared with prior art, gas meter, flow meter road of the present invention locking device have the advantage that due to Nut is cap nut of detaching proof, when on the external screw thread of the outlet side that the nut at bend pipe two ends is tightened on switch valve respectively and gas meter, flow meter After on the external screw thread of air inlet, people cannot tear open privately, privately install gas meter, flow meter, so as to effectively prevent from privately tearing open, The phenomenon stealing gas, gas leakage and gas meter, flow meter damage violating the regulations privately installed gas meter, flow meter and cause, and because bend pipe is used for and opens The one end closing the outlet side connection of valve is provided with one section of plum blossom mouth of pipe, and the inner hole wall of the outlet side of switch valve is provided with and the plum blossom mouth of pipe The plum blossom connected in star matching, therefore after bend pipe is tightened on the outlet side external screw thread of switch valve by cap nut of detaching proof, curved The plum blossom mouth of pipe of pipe can be inserted in the plum blossom connected in star on switch valve, and such bend pipe cannot switch valve relatively rotate, That is, cannot pull and be connected to the gas meter, flow meter of the bend pipe other end and make gas meter, flow meter run-off the straight, such that it is able to prevent gas meter, flow meter Stop operating and produce after tilting certain angle steals gas phenomenon.
When on the external screw thread of outlet side by cap nut of detaching proof, the two ends of bend pipe being spun on switch valve and the entering of gas meter, flow meter When on the external screw thread of gas port, people can be by the overcoat of general spanner rotary nut, the at this moment outer inclined-plane boss meeting putting Block reed, thus driving inner sleeve to be tightened on the external screw thread with the air inlet of gas meter, flow meter on the external screw thread of the outlet side of switch valve On, when contrary direction rotary sleeve again, the reed inside putting can produce elastic deformation, slides along the inclined-plane on inclined-plane boss Dynamic, thus inner sleeve can not be driven to rotate, in other words, only the two ends of bend pipe are screwed by rotating the overcoat of cap nut of detaching proof On the external screw thread of the outlet side of switch valve and on the external screw thread of air inlet of gas meter, flow meter, and can not again bend pipe be spun down, this The cap nut of detaching proof structure planting structure is simple, safe and reliable, easy to operate.
