Abstract
A self-threading type co-diameter pipe joint is mainly used for co-diameter PE pipe connection in a water pipeline in a drip irrigation system. An inner hole of the pipe joint is provided with an anti-clockwise threading screw thread at one end, and a clockwise threading screw thread at the other end. A to-be-connected PE plastic pipe is inserted into the hole of the pipe joint and certain axial force is exerted, then the pipe joint is rotated to enable the anti-clockwise threading screw thread and the clockwise threading screw thread to be screwed into the to-be-connected plastic pipe in the cutting manner at the same time, and along with the rotation of the pipe joint, the to-be-connected plastic pipe is automatically pulled into the pipe joint and is firmly connected with the pipe joint together, therefore, the purpose of connecting the plastic pipe is achieved. A rubber seal ring plays the function of sealing water. The pipe joint has a simple structure, is convenient to mount and use, and is reliable in connection function and low in cost.
Description
Technical field
The utility model relates to a kind of drip irrigation system and uses plastic water pipe joint.Belong to the pipeline connection technology field.
Background technique
At present drip irrigation technique is being widelyd popularize, and the water transport pipeline ways of connecting is of all kinds in the drip irrigation system, and wherein the quick replacable type joint is used morely, but present most of quick release coupling is that to form the number of spare parts of quick release coupling more by individual common problem, causes cost higher.For this reason, researched and developed a kind of number of spare parts few, change pipe joint easily.
Summary of the invention
The purpose of the utility model is to provide in a kind of drip irrigation system water transport pipeline to connect with Thread Forming TF formula indentical tube joint; This joint can connect and open the same footpath PE plastic tube of all size that uses in the drip irrigation system easily; This joint is a quick release coupling, and the assembly of joint is few, and linkage function is reliable; Cost is low, is fit to promote the use of.
The purpose of the utility model is realized by following proposal: a kind of Thread Forming TF formula indentical tube joint; Comprise the tubular configured joint body; Said tubular configured joint body has one to connect endoporus; Respectively there is one section tapping thread (screw thread has cutting edge, and is similar with the screw thread of screw die) at the endoporus two ends, while tapping thread be left-handed be dextrorotation.Respectively there is a groove at the endoporus two ends, and groove is to adorn rubber seal, and pipe joint just is equivalent to the outside thread that a screw die can be attacked plastic pipe.The root diameter of this pipe joint tapping thread is identical with connected plastic tube external diameter.Insert connected two sections pipes respectively in the hole on Thread Forming TF formula indentical tube joint both sides and impose certain axial force; Swivel joint; Because one of the tapping thread at two ends is left-handed in the pipe joint endoporus, another dextrorotation, so during swivel joint just connected pipe tapping outside thread and be drawn into the Kong Zhongyu joint to pipe simultaneously and link together; Connected pipe and joints is become one, reach the purpose that connects plastic tube.Rubber ring seals, and tapping thread works the pipe effect that connects.The outer surface of this pipe joint is made anti-skid design, and is manually actuated during installation.The counterrotating joint can be opened joint easily.This pipe joint material is harder plastics such as ABS, also can be metal.
The beneficial effect of the utility model is, its structure is very simple, has only a plastic part to form, and easy to install, linkage function is reliable, has reduced the cost of pipe joint effectively.This pipe joint also can be used for other plastic duct systems.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the tectonic maps of the utility model.
Fig. 2 is the sectional drawing of Thread Forming TF formula indentical tube joint.
1. fittings bodies among the figure, 2. rubber seal, 3. plastic tube, 4. dextrorotation tapping thread, 5. left-handed tapping thread.
Embodiment
In the embodiment shown in fig. 1; In the groove of fittings body (1) endoporus rubber seal (2) is housed; With in the connected hole of inserting fittings body (1) with footpath PE plastic tube and impose certain axial force; Swivel body (1) then will make left-handed tapping thread (5) and dextrorotation tapping thread (4) cut simultaneously and get in the plastic tube (3), along with the rotary plastic pipe (3) of fittings body (1) can be drawn in the fittings body (1) with fittings body (1) links together securely automatically, reaches the purpose of connection plastic tube.Rubber seal (2) plays sealing water.Fig. 2 is the sectional drawing of fittings body (1), and the intermediate portion of its expression fittings body (1) outer surface is an anti-skid design, convenient manual operations., needs can make connected plastic tube (3) withdraw from joint by counterrotating fittings body (1) when opening joint.
Claims (1)
1. a Thread Forming TF formula indentical tube joint comprises the tubular configured joint body, it is characterized in that: said tubular configured joint body has one to connect endoporus, and respectively there is one section tapping thread at the endoporus two ends, while tapping thread be left-handed be dextrorotation.
