Abstract
The utility model provides an elastic self pressure type sealed corrugated pipe connector which aims to provide a novel corrugated pipe connector which has the advantages of novel structure, simple, easy and quick processing and assembly, time saving, labor saving, height joint strength, good sealing performance and convenient installation and use, and the novel corrugated pipe connector is especially suitable for connection of corrugated pipes with large calibers. The utility model is composed of a buckling tile-shaped butt-joint outer pipe sleeve, wherein the convex edges of a pressing opening on both sides of the pipe sleeve are respectively connected with a sealing ring, the cross section of the sealing ring is in a cambered bottom butterfly shape, and grooves which are matched and connected with the convex edges of the pressing opening of the pipe sleeve are arranged on the top surface of the periphery of the sealing ring; a sealing cushion is clamped and connected with the butt-joint connecting surface of the pipe sleeve to be locked and fixed by connecting screws, and then, the utility model is formed. The utility model is suitable for connection of various corrugated plastic pipes, and is especially suitable for connection of PE and PVC corrugated pipes with large calibers. The utility model can be used for water discharging engineering and low-pressure water transportation engineering, and is a novel corrugated pipe connector.
Description
Technical field
The utility model relates to a kind of joiner of plastic tube, especially a kind of joiner that is applicable to waved plastic pipe.
Background technique
Along with the development and the extensive use of continuous development and technological progress, the especially plastic pipe of plastics industry, also more and more higher to the technical requirements of plastic pipe coupling device.In known technology, it mainly is the end interface heating enlarging of adopting tubing that existing plastic ripple pipeline connects, and the other end is installed O-ring seal and pegged graft; Adopt the grafting pipe box besides, two end connectors of bellows are installed O-ring seal earlier after, insert again to be connected in the pipe box and connect.Limit by its structure, existing connecting structure exists loaded down with trivial details, the effort of taking a lot of work of processing, joint strength is low, and sealability is relatively poor, especially is unsuitable for the connection of heavy caliber bellows, makes troubles to use.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of novel structure, and processing is equipped simple and easy fast, time saving and energy saving, be applicable to that especially more bigbore bellows connects the joint strength height, sealability is good, novel bellows joiner easy to install.
The technical scheme in the invention for solving the technical problem is: adopt button watt shape opposite outer tube sleeve, it is that ingot shape and periphery end face are shaped on the seal ring of joining connecting leg casing pressure mouth convex edge groove at the bottom of the arc that the pressure mouth convex edge of pipe box both sides connects cross section respectively, and folder connects sealing gasket again by the be locked bellows joiner of the elasticity self-pressure type sealing formed of connecting screw on the involutory junction surface of pipe box.During use, two seal rings are set with in two bellowss are connected first groove of termination, after the connection end face of two bellowss docked mutually, half pipe box of outer tube sleeve is installed in the bottom of two bellowss and presses the edge to link in the groove of seal ring in its both sides mouth, again second half pipe box is fastened its both sides mouth and press, promptly realized the connection of corrugated conduit along the groove that links seal ring and fastening after installing sealing gasket on the involutory surface of sleeve pipe, installing connecting bolt.Because the protruding tight card of pressure mouth of outer sleeve both sides is pressed in the groove of seal ring, again positive pressure is delivered to the both sides of seal ring, make the seal ring drive fit be affixed on bellows outer wall groove group, formed the reliable seal band of twice, thereby made seal ring play the effect of being tightly connected reliably.
Because technique scheme has been adopted in the utility model design, try out through test for several times again and show, it compared with prior art, has novel structure, design innovation, processing is equipped simple and easy fast, time saving and energy saving, point of attachment compressive strength height, advantage such as sealability is good, and is easy to install, be applicable to the connection of various waved plastic pipes, being particularly useful for the connection of bigbore PE, PVC bellows, can being widely used in drainage works and low-pressure water delivery engineering, is a kind of novel corrugated conduit joiner.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is the utility model embodiment's a concrete connection diagram.
Fig. 2 is that Fig. 1 embodiment's A--A is to sectional view.
Description of drawings: 1 bellows, 2 seal rings, 3 outer tube sleeve, 4 connecting screws, 5 sealing gaskets.
Embodiment
Embodiment as shown in Figure 1, the utility model is by button watt shape opposite outer tube sleeve 3, seal ring is that cross section is that ingot shape and periphery end face are shaped on the seal ring 2 of joining connecting leg casing pressure mouth convex edge groove at the bottom of the arc, the pressure mouth convex edge of pipe box 3 both sides connects seal ring 2 respectively, and the company's of folder sealing gasket 5 is locked by connecting screw 4 again on the involutory junction surface of pipe box 3.
Outer tube sleeve 2 in the utility model is for to be made by hard plastics injection mouldings such as PVC or PE; Also can make by metallic material such as cast iron, cast steel or aluminum alloys.
Claims (2)
1, a kind of bellows joiner of elasticity self-pressure type sealing, it comprises outer tube sleeve, seal ring, it is characterized in that outer tube sleeve is a button watt shape opposite pipe box (3), seal ring is that cross section is that ingot shape and periphery end face are shaped on the seal ring (2) of joining connecting leg casing pressure mouth convex edge groove at the bottom of the arc, the pressure mouth convex edge of pipe box (3) both sides connects seal ring (2) respectively, and the company's of folder sealing gasket (5) is locked by connecting screw (4) again on the involutory junction surface of pipe box (3).
2, bellows joiner according to claim 1 is characterized in that outer tube sleeve (3) is to be made by PVC plastics or PE plastics or cast iron or cast steel or aluminum alloy material.
