Abstract
A kind of quick bell-and-spigot pipe joint for compound pipe racks pressure valve, this joint comprises composite pipe, middle partition, pressure valve, strengthen steel plate, enhancing steel plate is provided with in port, composite pipe two ends, the middle partition is provided with in composite pipe, feature connects joint socket between composite pipe and composite pipe, through pressure valve pressure measurement, the anti-pressure ability of detecting tube inner seal ring, ensure sealing effect, 3PE anticorrosion composite pipe additionally arranges quality of connection and is guaranteed, telescopic action can be played when foundation settlement changes, prevent composite pipe to expand with heat and contract with cold fracture, non-leakage, increase the working life of composite pipe, easy construction, engineering cost is extremely low, every field can be widely used in supply, draining, the pipelines such as oil field use.
Description
Technical field
The utility model relates to connection tubing, is a kind of device connected for 3PE anticorrosion composite pipe tubing.
Technical background
At present, the known 3PE anticorrosion composite pipe for, draining is in process of deployment, in welding process, the port of 3PE anticorrosion composite pipe by Problems existing during weld heating is, destroy the anticorrosive coat of tubing, quality of connection between the port of composite pipe and the port of composite pipe is separated because heating to come off, cause anticorrosive coat to destroy, easily get rusty, rot to greatly reduce install the working life of 3PE anticorrosion composite pipe tubing to waste time and energy, welding difficulty is large.Construction requirement is high, must install electric wiring, and is equipped with soldering appliance, adds cost to construction, after connection tubing is connected with tubing electric welding, interface easily ftractures, and causes interface water leakage phenomenon to happen occasionally, tubing leaks affects the working life of tubing, both waste of manpower, and material resources bring again many inconvenience.
Summary of the invention
In order to overcome above-mentioned Problems existing, the purpose of this utility model to provide a kind of quick bell-and-spigot pipe joint for compound pipe racks pressure valve, a pressurizing valve installed by joint, the tubing mutually connected is suppressed detection, detect the sealing anti-pressure ability of tubing inside, avoid due to not prison welding, produce tubing welding junction cracking, leak and occur the generation of tubing corrosion phenomenon, such tubing does not ftracture, water-tight, namely improve working life, solve again the waste because of the human and material resources brought of constructing.
The utility model solves the technological scheme that its technical problem adopts, this joint comprises composite pipe, strengthen steel plate, middle partition, pressure valve, at composite pipe tubing two ends, port is provided with enhancing steel plate, the middle partition is provided with in composite pipe, pressure valve is provided with outside composite pipe, the mouth of pressure valve is the centre of two O-ring seals aimed on reinforced composite pipe tube head, during use, joint socket is connected between composite pipe and composite pipe, through pressure valve pressure measurement, the anti-pressure ability of detecting tube inner seal ring, reach the requirement of standard, to ensure sealing effect, make tubing unaffected for working life.
The beneficial effects of the utility model are, owing to have employed above-mentioned design proposal, 3PE anticorrosion composite pipe additionally arranges quality of connection and is guaranteed, and can play telescopic action when foundation settlement changes.Prevent composite pipe to expand with heat and contract with cold fracture, quick bell-and-spigot pipe connects good seal performance, non-leakage, and increase the working life of composite pipe, easy construction, engineering cost is extremely low, can be widely used in every field for pipelines such as, draining, oil fields.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is sectional view of the present utility model.
In figure 1, composite pipe, 2, middlely to cut off, 3, pressure valve, 4, strengthen steel plate, 5, reinforced composite pipe tube head, 6, joint, 7, O-ring seal.
Embodiment
This joint 6 comprises composite pipe 1, pressurizing valve 3, strengthen steel plate 4, the enhancing steel plate 4 of composite pipe 1 and two-port is shaping with composite pipe 1 one-step casting, in in the middle of cut off 2 also cast composite pipe 1 time one-step casting shaping, the outside jewel hole of composite pipe 1 is screwed in pressure valve 3 on composite pipe 1, and the mouth of pressure valve 3 aims at the centre of two O-ring seals 7 on reinforced composite pipe tube head 5, so that pressure measurement.
