Abstract
The utility model relates to a pipeline connecting device, in particular to a high-temperature-resistant polyethylene corrugated connecting pipe, which comprises a corrugated pipe and connecting joints, wherein one end of the corrugated pipe is a screw joint, the other end of the corrugated pipe is a nut joint, two ends of the corrugated pipe are both screw joints, or two ends of the corrugated pipe are both nut joints; the screw joint is a plastic joint or a metal joint, and is integrally formed with the corrugated pipe, the nut joint is a plastic joint or a metal joint, the corrugated pipe penetrates through the bottom of the nut joint and is movably connected with the bottom of the nut joint, a nut is internally provided with a sealing ring, and the plastic joints adopt enhanced POM plastics. The high-temperature-resistant polyethylene corrugated connecting pipe disclosed by the utility model has the advantages that the structure is simple, the design is reasonable, the processing is easy, the defects of a connecting pipe made from conventional hose materials that the high temperature resistance is poor, a water body has an abnormal taste, the service life is short are effectively avoided, the connecting joints adopt enhanced POM plastics, the strength is high, the service life is long, the processing is easy, the cost is low, the high-temperature-resistant polyethylene corrugated connecting pipe can be widely applied to pipeline connection in the fields of water heating, construction and the like, and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of assembling pipe joint, particularly a kind of refractory polyethylene corrugated connecting tube.
Background technique
Tubing is common pipe fittings in present daily life, connecting tube is often used in water supply, blowdown etc., the flexible pipe of commonly using at present belt lacing in some plastics water heating pipe fittings connects, and joint and flexible pipe are by riveting, and joint is rotating nut, intermediate hose is outer layer metal net connecting tube, this connecting tube is owing to adopting metal outer, easily corrosion, and the time is long touches or secondary is easy to the breakage that fractures while adjusting, cause connecting tube to leak, working life is short.Its manufacturing process complexity in addition, cost is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the refractory polyethylene corrugated connecting tube of simple in structure, durable in use, good stability.
Scheme of the present utility model is as follows:
A kind of refractory polyethylene corrugated connecting tube, comprise bellows and connecting head, and bellows one end is the screw rod joint, and the other end is the nut joint.
A kind of refractory polyethylene corrugated connecting tube, comprise bellows and connecting head, and the bellows two ends are the screw rod joint.
A kind of refractory polyethylene corrugated connecting tube, comprise bellows and connecting head, and the bellows two ends are the nut joint.
Described screw rod joint is plastic joint, one-body molded with bellows.
Described screw rod joint is metal joint.
Described nut joint is plastic joint, and bellows, through nut joint bottom and its flexible connection, is provided with seal ring in nut.
Described nut joint is metal joint, and bellows, through nut joint bottom and its flexible connection, is provided with seal ring in nut.
Described plastic joint adopts and strengthens the POM plastics.
The beneficial effects of the utility model:
Refractory polyethylene corrugated connecting tube of the present utility model, simple in structure, reasonable in design, easy processing, effectively avoided the connecting tube of traditional hose materials, and resistance to high temperature is poor, the shortcomings such as water body has peculiar smell, and working life is short, jointing adopts and strengthens POM, intensity is high, long service life, easy processing, cost is low, can be widely used in hot-water heating, the pipelines such as building connect, and reduce maintenance cost.
