Description

A kind of multi-angle rotary plastic conduit elbow

Technical field

This utility model is related to a kind of channel bend, and in particular to a kind of multi-angle rotary plastic conduit elbow.

Background technology

In pipe-line system, elbow is the pipe fitting for changing pipeline direction.Angularly divide, have 45 ° and 90 ° 180 ° three kinds it is most normal , according further to requirement of engineering also including 60 ° of grade other improper angle elbows.The material of elbow has cast iron, rustless steel, conjunction Jin Gang, malleable cast iron, carbon steel, non-ferrous metal and plastics etc..The mode being connected with pipe is had:Directly welding (the most frequently used mode) Flange connection, hot-melt adhesive paste, electric smelting connection, threaded connection and bayonet joint etc..Can be divided into according to production technology:Welding is curved Head, punched bend, push-making angle fitting, casting elbow, butt-welding elbow etc..

At present for plastic conduit elbow is generally by the way of threaded connection, the angle of existing elbow is all to fix not Become, and the joint of elbow is single, is merely able to change pipeline to a direction, be not suitable for the tubing of complexity, meeting Increase the pipe line in tubing so that pipeline connection is intricate to be not easy to staff the liquid in pipeline is seen Examine and control its flow.

Utility model content

Technical problem to be solved in the utility model is that the angle of bend fixation of traditional channel bend is not easy to adjustment The direction of pipeline, it is therefore intended that provide a kind of multi-angle rotary plastic conduit elbow, how solution is being changed without channel bend Situation changes the problem in the direction of pipeline by the multi-angle rotary of channel bend.

This utility model is achieved through the following technical solutions：

A kind of multi-angle rotary plastic conduit elbow, including cross pipe joint, the joint in the pipe joint Seam be socketed with flexible pipe, be provided with the joint of flexible pipe place keep hose bending angle support bar, the support bar bag Bull stick A, bull stick B are included, bull stick A is connected by rotating shaft with bull stick B, on all joints of the pipe joint, are provided with baffle plate, One end of the baffle plate passes through the side joint tube wall that baffle plate is located to opposite side joint tube wall inwall.

Cross pipe joint in this utility model generally comprises four joints, and flexible pipe is used for the direction for changing pipeline, uses Family can all be socketed flexible pipe or one of which joint or two joints as needed on four joints or three connect Flexible pipe is socketed on head, is to ensure that current only pass through from the joint of connecting cylinder, other untapped joints is blocked with baffle plate；It is soft One end of pipe is connected with joint, and one end is connected with pipeline, and flexible pipe is poor due to its support effect, now needs, by external force, to keep soft The angle of bend of pipe, also functions to supporting role to pipeline, and support bar serves supporting role to flexible pipe and pipeline, with pipeline Angle change, by the appropriate length for adjusting support bar of the rotation of the bull stick A in support bar and bull stick B, support angle.

Female thread is installed on the inwall of the flexible pipe.The pipeline that the female thread of hose inner wall can not only be connected with flexible pipe Cooperate, additionally it is possible to play cushioning effect, weaken the impact strength of water, extend the service life of flexible pipe.

Bandage is installed on the flexible pipe, the bandage is located at the junction of flexible pipe and joint.The bandage is from the inside to the outside Include waterproof layer, drying layer, fixed layer successively, the waterproof layer is close to flexible pipe outer wall, and drying layer is connected with waterproof layer and is done Desiccant is filled with dry layer, fixed layer is connected with waterproof layer, drying layer and fixed layer and is provided with VELCRO.Bandage is used for Flexible pipe is fixed up with joint, the joining place leak of flexible pipe and joint is prevented.

Water blockoff pad is fixed with one end of the baffle plate top connection tube wall inwall contact, the water blockoff pad adopts rubber blanket. Water blockoff pad is the rubber with certain deformation, during baffle plate water blockoff, if baffle plate can not be fully sealed with inner nosepiece wall, that Joint will leak, water plugging effect is bad, and water blockoff pad after the effect by power can pressed joint inwall, water plugging effect It is good, moreover it is possible to avoid inner-walls of duct from being damaged by pressure by baffle plate or scrape damage.

The flexible pipe adopts PVC corrugated flexible hoses, is wound with tinsel on the excircle of the flexible pipe.Tinsel also functions to prop up The effect of support flexible pipe.

This utility model compared with prior art, has the following advantages and advantages：

1st, flexible pipe is accessed in a kind of multi-angle rotary plastic conduit elbow of this utility model and realizes elbow multi-angle rotary, Using this utility model, pipeline just can freely change direction；

2nd, a kind of multi-angle rotary plastic conduit elbow of this utility model can pass through the passage and water of baffle controls current The flow of stream；

3rd, a kind of multi-angle rotary plastic conduit elbow of this utility model make use of simple strap configurations, be effectively prevented There is be connected shakiness and the situation of leak in pipeline and joint；

4th, a kind of multi-angle rotary plastic conduit elbow structure design of this utility model is simple, easy for installation, both with biography The function of the elbow of system, changes the shortcoming that traditional elbow can not be changed direction again.
