Abstract
The utility model relates to a rigid plastic pipeline connection device which is suitable for connection of rigid plastic pipelines with large diameters. The rigid plastic pipeline connection device is composed of plastic connector bodies, rubber sealing rings, a pair of clamp sleeves and fastening bolts. The plastic connector bodies are fixed on pipelines which need to be connected and the plastic connector bodies are provided with bosses which are matched with grooves of the pair of the clamp sleeves and are conducted axial positioning to the pipelines. The rubber sealing rings are sleeved on the plastic connector bodies and are used for sealing the pipelines. Rubber sealing ring positioning grooves of the pair of the clamp sleeve support and fix the rubber sealing rings, and the whole pipe connection device is fastened through a pair of fastening bolts. According to the rigid plastic pipeline connection device, the technical problems that a glue joint way and a fusion welding way are not beneficial for being used repeatedly, a flange connection and installation procedure is complex, and a groove connection reduces loading capacity of the pipelines are solved, wherein the problems are caused in the connection of the rigid plastic pipelines. The rigid plastic pipeline connection device is simple in structure, convenient to disassemble and assemble, and can be widely used in the connection field of the rigid plastic pipelines with the large diameters.
Description
Technical field
The utility model relates to a kind of assembling pipe joint, is specifically related to a kind of hard plastic pipe connection set, is applicable to the connection of heavy caliber hard plastic pipe.
Background technique
Hard plastic pipe is used more and more wider at aspects such as plumbing, pressurized air, chemical pipeline, oil-piping, grouting pipelines, also more and more stricter and diversified to the requirement of pipeline connection and sealing.Prior art three kinds of technological schemes of the many employings of connection to hard plastic pipe, all have some defectives: one, glue connection, hot melt connect, and are not easy to dismantle after connecting, and can't repeat the dismounting use, cause the pipeline waste; Two, flange connects, and step is comparatively loaded down with trivial details aspect installation, dismounting, pipeline maintenance, causes operating efficiency lower; Three, groove pipeline Placement, the processing groove can affect the bearing capacity of tubing on pipeline.The shortcoming of existing Placement is needed a kind of simple and convenient, cheap, solid and reliable New junction device badly and is addressed the above problem.
Summary of the invention
The purpose of this utility model is to solve the technical problem not convenient or that bearing capacity reduces that removes and installs that exists on existing hard plastic pipe connection, sealing technique, a kind of Novel rigid plastic assembling pipe joint is provided, makes this type of pipeline connect, seal more simple and convenient, cheap, solid and reliable.
A kind of Novel rigid plastic assembling pipe joint technological scheme of the present utility model is as follows:
A kind of hard plastic pipe connection set, comprise a pair of plastic joint body 4 that is fixed on pipeline 5 terminations, be enclosed within the rubber seal 2 on a pair of plastic joint body 4, coordinate with the plastic joint body connection set is carried out the paired cutting ferrule 1 that axially locating supports rubber seal location simultaneously, and the clamping bolt 3 of a pair of fastening cutting ferrule.
The mode of described plastic joint body 4 by pre-glue or welding is fixed on pipeline 5 terminations, comprises being positioned at away from the boss of pipeline 5 interface one ends and the sealing area that is inserted in rubber seal 2.
Described paired cutting ferrule 1 comprises the groove that has coordinated the axially locating effect with plastic joint body boss, rubber seal location groove and bolt mounting zone.The preferred round end oval neck of described clamping bolt clamping bolt.
The utility model is by the boss of two plastic joint bodies that are fixed on pipeline external surface and the groove fit of cutting ferrule in pairs, assembling pipe joint is carried out axially locating with fixing, being enclosed within two rubber seal on the plastic joint body by one seals, locate groove by the rubber seal of paired cutting ferrule rubber seal is enclosed location and supporting effect, only need two round end oval neck clamping bolts to carry out fastening to the paired card cover, so connecting component apparatus is simple and sealing is reliable, installation, convenient disassembly increase substantially operating efficiency.

Embodiment
As Fig. 1, shown in Figure 6, the hard plastic pipe connection set, comprise plastic joint body 4, rubber seal 2, paired cutting ferrule 1, clamping bolt 3, the plastic joint body has boss away from pipe joint one end, have in pairs the fixedly rubber seal location groove of rubber seal 2 of the groove corresponding with boss and on cutting ferrule 1, clamping bolt 3 is fixed cutting ferrule by the through hole on paired cutting ferrule 1.
Installation process is as follows:
As shown in Figure 5, select and glued joint or the welding mode will be fixed to pipeline external surface with the plastic joint body 4 of material with tubing;
As shown in Figure 6, the pipeline with connection plastic joint body 4 inserts rubber seal 2;
As shown in Figure 6, the recess region that paired card is put is aimed at the boss of plastic joint body, rubber seal is fixed in the rubber seal location groove of paired cutting ferrule, installs and fastening two round end oval neck clamping bolts, namely completes pipeline and connects.
