Abstract
The utility model belongs to a quick pipeline joint. A sealed locking member and a shim are arranged between a steel pipe and a nipple. The inner circle of the nipple is contacted with the surface of the steel pipe. An external nut is connected with the outer screw of the nipple. A pushing shim forces to the sealed locking member, achieving the purposes of sealing and locking. The utility model has the advantages of simple structure and convenient construction, and is applicable to quickly connecting pipelines in any situation.
Description
The utility model belongs to a kind of pipeline does not have a rapid pipe joint.
In the connection of the pipe fitting that present China generally adopts, as all adopting scyewed joint in the pipeline of water, vapour, oil and other working fluid mostly, pipe needs machining screw during construction, and processing is required great effort, speed of application is slow, and need twine fiber crops and coating, loading and unloading inconvenience; And after installing again because of a variety of causes, cause water clock serious, influence construction quality.
China utility model patent CN2079696V discloses a kind of piecing devices, its basic structure includes fittings body, collar nut, the clips courage, the fittings body cylindrical has one section outside thread, interior is spill awl chamber, collar nut is screwed on the outside thread of fittings body, the clips courage is made by elastic material, two ends are conical tapered sleeve, one end stretches in the spill awl chamber of fittings body, the other end stretches in the spill awl chamber of collar nut, by tightening collar nut, courage is pressed from both sides in crush seal, reaches the purpose of sealed attachment, the piecing devices complex structure of this structure, the processing request strictness.
China utility model patent CN2073695V discloses another kind of pipeline is not had a coupling, be characterized between steel pipe and spigot, being equipped with locking plate, rubber ring, and fastening and sealing by outer connected nut thrust, though it is comparatively simple that this pipeline does not have a coupling structure, but owing to the locking plate device must be housed and locking plate is an open type, because that tubing irregular caused is poorly sealed.
The purpose of this utility model is to avoid the deficiency of above-mentioned prior art, provide a kind of rational in infrastructure, processing pipeline simple, with low cost, easy to loading and unloading, good seal performance do not have a rapid pipe joint.
The purpose of this utility model can reach by following measure: a sealing locking element and a pad are housed, this pad and sealing locking element plane contact between steel pipe and spigot.
Said sealing locking element can be rubber, asbestos, also can be graphite packing and other sealing material.
The utility model is owing to only need be equipped with a sealing locking element and a pad between steel pipe and spigot, so structure is simple especially, it is all very convenient to process, install, simultaneously according to usage requirement, the material of conversion sealing locking element can be used under low temperature, high temperature, high pressure, any occasion such as corrosion-resistant.
Accompanying drawing is the utility model section of structure.
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, at one section outside thread of cylindrical processing of spigot (5), the exterior edge face has one section face that has tapering inwards, and the inside is provided with sealing locking element (4) and pad (3), sealing locking element (4) promptly can be rubber, asbestos, also can be graphite packing or other sealing material.The interior circle of spigot (5) contacts with steel pipe (1) surface, and outer nut (2) connects with spigot (5) outside thread.
During installation, with outer nut (2) install to steel pipe (1) and pack into successively pad (3), the sealing locking element (4), then steel pipe (1) is inserted in the spigot (5), and will seal the outer end conical surface that locking element (4) pushes spigot (5), exert pressure with nut (2) Thurst washer (3) and to sealing locking element (4) at last, reach the purpose of sealing and locking.
The utility model can be used for any occasion of pipeline, according to the pipe fitting that will be processed into various tubing, as elbow, threeway, valve, pipe collar, plug etc., can save existing movable joint in the practical application.
Claims (3)
1, a kind of pipeline does not have a rapid pipe joint, it is characterized in that: be provided with sealing locking element (4) between steel pipe (1) and spigot (5).
2, pipeline according to claim 1 does not have a rapid pipe joint, it is characterized in that: also be provided with a pad (3) between steel pipe (1) and the spigot (5), with sealing locking element (4) plane contact.
