Description
Technical Field
The utility model belongs to the technical field of gas pipe connects, concretely relates to novel joint for gas pipeline.
Background
With the introduction of gas such as urban and rural pipeline gas, natural gas, liquefied petroleum gas, biogas and the like into thousands of households, clean fuel which is convenient to use, sanitary and pollution-free is brought to people, the gas is mainly communicated among combustion appliances through gas pipe joints, the gas pipe joints in the prior art have poor sealing performance, high production cost, complex structure and the like, and aiming at the defects, a novel joint for a gas pipeline which has a simple structure, good sealing performance and convenient replacement is required to be developed; therefore, it is very important to develop a novel joint for a gas pipeline, which has simple structure, good sealing performance and convenient replacement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, and provide a simple structure, sealing performance is good and change convenient novel joint for gas pipeline.
The purpose of the utility model is realized like this: the utility model provides a novel joint for gas pipeline, it is including connecting the body, connect fixedly on the body to be provided with the coupling nut who is used for connecting external pipeline, it is connected with the lock nut who is used for locking through threaded connection area to connect the body, lock nut's inside is provided with the gasket, the gasket is connected with the bellows that is used for carrying the gas, bellows connection has the packing ring.
The cross-sectional view shape of the gasket along the axial direction is trapezoidal, and the gasket is in a hollow boss structure.
The locking nut is of a hollow structure, and the diameter of the smallest hole is larger than the outer diameter of the corrugated pipe.
The gasket and the gasket are made of rubber materials which are extruded and shrunk.
The locking nut is connected with the joint body through threads.
The joint body is of a hollow structure.
The utility model has the advantages that: the utility model has the advantages of convenient installation and good sealing performance, adopts the gasket and the gasket which can be made of rubber and can stretch out and draw back for sealing, and can effectively prevent the leakage of natural gas due to the flexible performance of the rubber; the locking nut is designed to be convenient to install, and the joint body and the corrugated pipe can be gradually connected by continuously rotating the locking nut; in addition, the gasket and the washer can be conveniently replaced when the gasket and the washer need to be replaced and the locknut is unscrewed; therefore, the utility model has the advantages of simple structure, good sealing performance and convenient replacement.
Drawings
Fig. 1 is a front view of the novel joint for a gas pipeline of the present invention.
Fig. 2 is a schematic view of the structure of fig. 1.
In the figure: 1. the connector comprises a connector body 2, a connector nut 3, a locking nut 4, a corrugated pipe 5, a gasket 6, a gasket 7 and a threaded connecting belt.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1
As shown in fig. 1-2, a new joint for gas pipes comprises a joint body 1, the joint body 1 is fixedly provided with a joint nut 2 for connecting an external pipeline, the joint body 1 is connected with a locking nut 3 for locking through a threaded connecting belt, a gasket 5 is arranged inside the locking nut 3, the gasket 5 is connected with a corrugated pipe 4 used for conveying gas, the corrugated pipe 4 is connected with a gasket 6, the shape of the cross section of the gasket 6 along the axial direction is a trapezoid, the washer 6 is a hollow boss structure, the lock nut 3 is a hollow structure, the diameter of the smallest hole is larger than the outer diameter of the corrugated pipe 4, the gasket 5 and the washer 6 are made of rubber materials which are extruded and shrunk, the locking nut 3 is connected with the joint body 1 through threads, and the joint body 1 is of a hollow structure.
The utility model has the advantages of convenient installation and good sealing performance, adopts the gasket and the gasket which can be made of rubber and can stretch out and draw back for sealing, and can effectively prevent the leakage of natural gas due to the flexible performance of the rubber; the locking nut is designed to be convenient to install, and the joint body and the corrugated pipe can be gradually connected by continuously rotating the locking nut; in addition, the gasket and the washer can be conveniently replaced when the gasket and the washer need to be replaced and the locknut is unscrewed; when the corrugated pipe is installed, the corrugated pipe penetrates through a locking nut, then a gasket is sleeved on the corrugated pipe, a small part of the head of the corrugated pipe is expanded outwards by a tool such as a clamp, then the part of the corrugated pipe expanded outwards is moved into the locking nut, meanwhile, a boss-shaped gasket with a large end facing inwards is placed, and the large end of the gasket is provided with a circle extending outwards, so that when the corrugated pipe is connected with a joint body, the joint body can press the part of the corrugated pipe expanded outwards through the circle extending outwards from the large end, and a sealing structure is formed; the connecting mode is convenient for replacing accessories, and the purpose of selecting the length can be achieved by cutting the corrugated pipe; therefore, the utility model has the advantages of simple structure, good sealing performance and convenient replacement.
The present invention is further described in the detailed description, rather than in the limited form thereof, and it will be obvious to those skilled in the art that changes may be made in the structure without departing from the spirit and scope of the invention, and it is intended that all such changes be covered by the appended claims.
