Description
The technical field is as follows:
the utility model relates to a plugging device especially relates to a gas pipeline plugging device.
Background art:
in the natural gas conveying process, a main pipeline is laid underground, when a user enters the natural gas conveying process, as shown in figure 1 or 2, a connecting pipe communicated with the main pipeline is vertically buried outdoors, the connecting pipe is turned upwards to the ground from the underground, one end, turned upwards to the ground, of the connecting pipe is connected with a tee joint, the top of the tee joint is blocked through a blind plate, and an outlet in the middle of the tee joint is communicated with a house-entering pipe of one unit or a plurality of units.
In the traditional natural gas pipeline arrangement, a valve is arranged on only one section of the service pipe entering the house, and in order to prevent the service pipe from being considered damaged, the valve is not arranged on the section of the service pipe located outdoors and the section of the connecting pipe exposed out of the ground; in the arrangement mode, when the indoor section of the service pipe is damaged and leaked or the valve is damaged and leaked, the valve on the main pipeline can be closed and then maintained or replaced, so that large-area gas is stopped and supplied, and loss is caused to users; especially in the winter heating season in the north, the heat pump system can cause huge loss to users. Therefore, it is necessary to develop a gas pipeline plugging device to ensure the use of gas right of users.
The utility model has the following contents:
in order to solve the technical problem, an object of the present invention is to provide a gas pipeline plugging device.
The utility model discloses by following technical scheme implement: the utility model provides a gas pipeline plugging device, includes the screw rod, the one end spiro union of screw rod has last lock mother the other end of screw rod is overlapped in proper order and is equipped with clamp plate, rubber seal pad and lock mother down, the clamp plate with screw rod fixed connection, lock mother down with the screw rod spiro union, rubber seal pad by the clamp plate with lock mother down presss from both sides tightly.
Furthermore, the outer side of the upper locking nut is provided with an external thread.
Furthermore, a diffusion check hole is arranged on the upper lock nut in a penetrating mode, and a plugging screw is screwed in the diffusion check hole.
The utility model has the advantages that: the utility model has simple structure and convenient use, when the indoor section of the house entering pipe is damaged and leaked or the valve is damaged and leaked and needs maintenance, the blind plate at the top of the tee joint is opened, the screw rod is stretched into the tee joint, one end provided with the rubber sealing gasket is downward, the upper locking nut is fixed with the tee joint by screwing, the screw rod is rotated, the screw rod is stretched into the connecting pipe downward, and the sealing of the connecting pipe is realized by the rubber sealing gasket; then opening a diffusion check hole, detecting whether gas leaks or not, if so, continuing to rotate the screw rod, and adjusting the position between the rubber sealing gasket and the connecting pipe until no gas leaks (if the sealing is not tight, gas leaks, on one hand, potential safety hazards exist after the gas leaks indoors, and on the other hand, after the gas enters the service pipe, explosion risks exist when sparks happen in the maintenance process); and then closing the diffusion inspection hole, and maintaining and replacing the service pipe or the valve. Only one unit or a plurality of unit users are communicated by the tee joint, and the problem of large-area gas supply stop in the traditional mode of closing a main pipeline valve is solved.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic diagram of a conventional connection pipe and a service pipe;
FIG. 2 is a schematic diagram of the connection of a connecting pipe, a tee and a service pipe;
fig. 3 is a schematic view of the present invention.
In the figure: the device comprises a screw rod 1, an upper locking nut 2, a pressing plate 3, a rubber sealing gasket 4, a lower locking nut 5, a diffusion inspection hole 6, a plugging screw 7, a connecting pipe 8, a house service pipe 9, a valve 10 and a tee joint 11.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a gas pipeline plugging device, includes screw rod 1, and the one end spiro union of screw rod 1 has last lock 2, and the outer side of locking 2 is equipped with the external screw thread that matches with tee bend 11's internal thread, overlaps in proper order at the other end of screw rod 1 and is equipped with clamp plate 3, rubber packing 4 and lock 5 down, and clamp plate 3 and screw rod 1 fixed connection, lock 5 and screw rod 1 spiro union down, and rubber packing 4 is pressed from both sides tightly by clamp plate 3 and lock 5 down.
A diffusion check hole 6 is arranged on the upper lock nut 2 in a penetrating way, and a plugging screw 7 is screwed in the diffusion check hole 6.
The working principle is as follows:
when the indoor section of the house entering pipe 9 is damaged and leaks or the valve 10 is damaged and leaks and needs to be maintained, a blind plate at the top of the tee joint 11 is opened, the screw rod 1 is stretched into the tee joint 11, one end provided with the rubber sealing gasket 4 is downward, the upper locking nut 2 is fixedly connected with the tee joint 11 in a threaded manner, the screw rod 1 is rotated, the screw rod 1 is stretched into the connecting pipe 8 downward, and the rubber sealing gasket 4 is utilized to realize the sealing of the connecting pipe 8;
then, opening the diffusion check hole 6, detecting whether air is leaked or not, if the air is still leaked, continuing to rotate the screw rod 1, and adjusting the position between the rubber sealing gasket 4 and the connecting pipe 8 until no gas is leaked (if the sealing is not tight, the gas is leaked, on one hand, potential safety hazards exist after the gas is leaked indoors, and on the other hand, after the gas enters the household pipe 9, explosion risks exist when sparks are encountered in the maintenance process); the diffusion inspection hole 6 is then closed, and the service pipe 9 or the valve 10 is repaired and replaced.
