Abstract
The invention discloses a connecting component for large-diameter hoop type GRP (glass reinforced plastic) pipes. The connecting component is used for connecting the GRP pipes. The GRP pipes comprise a first pipe and a second pipe. The connecting component is characterized by comprising a sealing ring connecting ports of the two pipes; ferrules used for nesting the pipes are arranged on the left side and the right side of the sealing ring; and the sealing ring and the ferrules are locked and fixed through a hoop and a bolt pair. By the aid of the connecting component, the sealing performance of the pipes can be enhanced, the pipes can be prevented from being pulled out by external force, mounting is convenient and fast, and the connecting component is applicable to connection of large-diameter pipelines and construction and emergency maintenance of pipeline burst and water leakage of the pipelines.
Description
Technical field
The invention belongs to fiberglass plastic clamp sand pipe associated conduit laying construction and fiberglass plastic clamp sand pipe tubing connection pipe fitting production and manufacture field, is a kind of heavy caliber cuff formula frp pipe connection pipe fitting.
Background technique
Domestic existing fiber reinforced plastic pipe connects sealed pipe fittings, is mostly to adopt bayonet joint pipe fitting, and this connection pipe fitting is only applicable to caliber and connects at the tubing below 1 meter.The existent defect when tubing at caliber more than 1 meter is used: 1., when tubing docks with pipe fitting installation, must be furnished with large-scale docking and advance adapter equipment just can complete, but be to realize in pipeline laying construction place.2. necessary disposable success while taking over, not in place, defective once socket joint connection, pipe fitting is difficult to deviate to reinstall from tubing again, haves much room for improvement.
Chinese patent is rear CN201210174780.2 openly, the name of innovation and creation is called " a kind of seal sleeve interface for connecting glass fiber reinforced plastic and for the fiber reinforced plastic pipe of this interface ", the deficiency of this patent is likely because the excessive sealing effect that causes of hydraulic pressure is not fine, and overall structure does not possess the function that prevents that pipeline from falling back.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of good sealing effect is provided, anti-tubing is deviate from and connection part is easily installed.
In order to realize the object of this invention, the technological scheme of employing is as follows:
A kind of heavy caliber cuff formula frp pipe connection part, for momentary connection glass-reinforced plastic material, described frp pipe comprises the first tubing and the second tubing, comprise the seal ring that connects two pipe ends, the described seal ring left and right sides is provided with for entangling the lasso of tubing, and described seal ring and lasso are locked by bolt pair by cuff.
Particularly, adopt the present invention first to allow two pipe ends insert in seal ring, their close contacts are coordinated, then in the seal ring left and right sides that has connected tubing, lasso is set and entangles two tubing, prevent that them from falling back out, finally by cuff, the integral body coupling together is fixed to locking above.
Preferably, described seal ring shaft section is I shape.
The present invention, by using the seal ring of I shape can make the port of first, second tubing contact with it with intimate is convenient, reaches good sealing effect.
Preferably, described lasso comprises the first lasso and the second lasso, and the first lasso correspondence is entangled the first tubing, and the second lasso correspondence is entangled the second tubing.
Preferably, described first, second lasso is shaped as cylindrical shape or sheet type.
Preferably, first, second described lasso inwall is equipped with and sets one's teeth on edge.
It is in order to prevent falling back of tubing that the lasso inwall is here provided with the structure of setting one's teeth on edge.
Preferably, described cuff is provided with opening, and cuff opening both sides arrange hangers.
Preferably, described hangers evenly has two or more bolts hole.
The present invention is compared with the prior art, and the beneficial effect having is:
1. when in pipe, water supply pressure increases, seal ring due to its I-shaped structure will be by inner tube wall subsides tightr;
When tubing produces external force tubing because of extraneous factor will be when releasing in pipe fitting, the setting one's teeth on edge to produce in distortion of lasso inwall turns over tubing bellmouth outer wall embraced tightlyer, therefore plays and prevents the object of tubing from deviating from pipe fitting;
3. manually easy for installation, quick;
4. due to the convenient and easy use operation of integrated connection mode of the present invention, can be used for the connection of large diameter pipeline.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the connection part of heavy caliber cuff formula frp pipe, for momentary connection glass-reinforced plastic material, described frp pipe comprises the first tubing 1-I and the second tubing 1-II, this connection part comprises the seal ring 2 that connects two pipe ends, described seal ring 2 left and right sides are provided with for entangling the lasso 3 of tubing, and described seal ring 2 and lasso 3 are locked by bolt pair by cuff 4.
Described lasso 3 comprises the first lasso 3-I and the second lasso 3-II, and described the first lasso 3-I correspondence is entangled the first tubing 1-I, and the second lasso 3-II correspondence is entangled the second tubing 1-I.
Described seal ring 2, for adopting the rubber seal that shaft section is I shape, entangles the first tubing 1-I and the second tubing 1-II port, when inside water pressure increases, can make the inwall of seal ring 2 more be close to tubing, increases sealing.Described lasso 3 is cylindrical shape, inwall is provided with sets one's teeth on edge 6, after entangling pipe end, set one's teeth on edge and 6 be close to tubing docking joint socket outer wall, when tubing produces external force tubing because of extraneous factor will be when releasing in pipe fitting, set one's teeth on edge can produce in distortion and turns over tubing bellmouth outer wall is embraced tightlyer, therefore play and prevent the object of tubing from deviating from pipe fitting.
Cuff shown in Fig. 9 is selected stainless steel material, reaches the connection of tubing after lasso entangles tubing by lock bolt.
Easy accessibility of the present invention, can repeatedly be used and repeat to install, but also is applicable to the construction repairing that pipeline burst leaks.
