Abstract

The invention relates to a polyethylene plastic steel winding drain pipe clamping hoop, and belongs to the technical field of large diameter buried drainage pipes. The a polyethylene plastic steel winding drain pipe clamping hoop comprises a pair of semicircular clamping hoops (5), a locking spiral ring (6), an arc pressing plate (7), an elastic sealing rubber sheet (8), a valgus blank pressing (9), and a bolt group (10). The polyethylene plastic steel winding drain pipe clamping hoop utilizes a locking spiral ring (6) structure so as to bring convenience to lock spiral steel belts on the outer surfaces of two pipes and enable the clamping hoop to be axially fixed with the pipes, and therefore the loosing of the two pipes is avoided. The polyethylene plastic steel winding drain pipe clamping hoop is tightly pressed on the spiral steel belts on the outer surfaces of the two pipes and a water plugging block (3) in a spiral groove through the valgus blank pressing (9) and the bolt group (10) by utilizing the arc pressing plate (7) and the elastic sealing rubber sheet (8), so that a good water sealing effect is achieved.

Description

Polyethylene plastic steel wound drain pipe clip

Technical field

The present invention relates to the connection set of the buried draining drain pipe of heavy caliber, particularly a kind of connection clip of polyethylene plastic steel wound drain pipe.

Background technique

The polyethylene plastic steel wound drain pipe is owing to have economic performance preferably and higher ring stiffness and better antiseptic power, in the buried draining blowdown of municipal heavy caliber engineering pipeline, be applied gradually, belong to novel pipeline, the Placement that is used in the market this pipeline is that stainless steel lathe dog is connected with Electric thermal smelting belt, because these two kinds of Placements exist insufficiency of function and defective, because the outer surface of this pipeline is to twine along helix with steel band, the employing Electric thermal smelting belt connects, need use first plastic welding gun and plastic welding rod, junction point at the bottom of the two tube opening spiral chutes is welded, allow again the workmen crawl in the pipe, with special device inner tube wall two interface tube places are supported and lay Electric thermal smelting belt energising welding, because anoxic in the pipe, workmen's labor intensity is large, operating condition is poor, and caliber is during less than people's height, the workmen can not inlet pipe in construction, can not construct in the place that water is arranged, narrow limitation is very large, and efficient is low, and speed of application is extremely slow; The subject matter that adopts stainless steel lathe dog to connect be the anti-corrosive properties of clip own be good at poor, very easily by water content, salt, contain alkali, contain the earth corrosion of acidity or erode, working life is short, sealing Watertightness can be also undesirable.

Summary of the invention

For deficiency and the defective that solves above-mentioned two kinds of connecting means, it is better with antiseptic property to the invention provides a kind of sealing, and more convenient operation is pipe joint hoop efficiently.

For performance and the effect that reaches above-mentioned Placement, a kind of polyethylene plastic steel wound drain pipe that aims at of the present invention connects and the clip of design, comprise that the flanging of radially turning up of two halves ring-shaped clip is provided with the lock bolt group up and down, the axial two ends of clip are provided with the set and locking screw ring, be provided with arc pressuring plate between two whorls, the clip inwall posts the elastic packing film.

Relative prior art, the present invention has obvious beneficial effect: the set and locking screw ring at the axial two ends of described clip plays clip when mounted to the axial restraint effect of two pipes, and the anticreep bit function is arranged; Arc pressuring plate between inboard two whorls of described clip presses with the elastic packing film and cooperates, and can play more effective sealing and close the water effect.

Embodiment

Below the invention will be described further by reference to the accompanying drawings by specific embodiment:

Extremely shown in Figure 5 such as Fig. 1, a kind of connection clip of polyethylene plastic steel wound drain pipe, two halves clip (5) is to be made by materials such as a pair of plastics or glass fiber reinforced plastic about it, before two pipelines (1) and (2) connection construction, first with the groove between the helical steel band of two tube openings, blob of viscose with plastics weldering or placement respective shapes is filled to consistent with the steel band height, make it to form one water blockoff wall (3) and the helical steel band of two pipes is alignd along Hand of spiral, as Fig. 2 up and down two halves clip (5) be positioned over respectively up and down two ends in the middle of pipeline (1) and pipeline (2) interface, press the up and down flanging of radially turning up (9) of two halves clip (5) by tightening up such as the bolt group (10) among Fig. 1, make the elastic packing film (8) of arc pressuring plate (7) the compression clamp inwall of clip (5), thereby reach clip (5) and two pipe end cylindrical firm and reliable connection, sealing is closed water spot and is dripped and do not leak, the set and locking screw ring (6) at the axial two ends of clip and the winding screw steel band (4) of two tube opening cylindricals chucking, two pipes can not be broken away from from clip, reach the effect of axial locking two pipes, this clip antiseptic property is good, good weatherability, but submersible, but all-weather construction.

Claims

1. polyethylene plastic steel wound drain pipe clip, it is characterized in that: consisted of by clip body (5), elastic packing film (8), connecting bolt group (10), the clip body by two halves clip up and down by the connecting bolt group, lock onto between two tube openings, connect sealing and locking two pipes to rise, prevent the effect that two pipes and clip break away from.

2. clip according to claim 1 is characterized in that: the inboard intermediate portion of the up and down two halves clip of described clip posts elastic packing film (8).

3. clip according to claim 1 is characterized in that: the inboard middle arc pressuring plate (7) that is designed with of described clip; Axially two ends are provided with the set and locking screw ring (6) consistent with the helical steel band pitch of pipeline appearance.

4. clip according to claim 1 is characterized in that: the hoop left and right sides of described clip be respectively equipped with the flanging of turning up (9) with and lock bolt group (10).

5. clip according to claim 1, it is characterized in that: described clip is made by plastics or glass fiber reinforced plastic.

6. elastic sealing strip according to claim 2 (8) is characterized in that: described elastic sealing strip can by the soft materials such as rubber, plastics or silica gel of foaming with and the water-proofing material of pitch class made.
