Abstract
Disclosed is a high pressure inflation hose that can guide static electricity and is composed of a hose (4), a connector (1), a locking set (2), and a static electricity guiding component. The utility model is characterized in that the static electricity guiding component is a metal tightening spring (3) which is arranged at the two ends of the inner chamber of the hose (4) and is connected with the connector (1); a static electricity guiding high pressure inflation hose integrity is formed by the hose and the tightening set on the connectors at the two ends of the metal tightening spring, which can not only retain the original production art, the connection art and the material performance of the hose, but also guarantee the reliable and complete static electricity guiding effect.
Description
Technical field
The utility model relates to a kind of high-pressure aerated flexible pipe of leading static, and pipe is led electrostatic technique and structure class for the high-pressure aerated flexible pipe of plastics in belonging to.
Background technique
Technique known shows: when gas flowed in pipeline, because of the relative movement meeting generation static of gas and tube wall, and gas flow rate was fast more, and the static content of generation is big more; For the metal conduction pipe, adopt good grounding measures promptly can eliminate the harm of static.But when the body material was insulator, simple ground connection was not dealt with problems, the electrostatic charge accumulation that this moment, gas flow produced can not move on tube wall, when the electrostatic charge accumulation at this place when its potential difference is enough to puncture this gas medium, will produce sparkover, jeopardize safety; Particularly it is dangerous when conveying gas is inflammable gas and oxygen.
Produce electrostatic problem in order to solve in the gas transmission of insulator tubing, at present known technological method is by following several:
One, before the tube forming, in raw material, adds conduction class materials such as copper powder, body after the moulding is had necessarily lead electrostatic capacity;
Two, built-in metal twine in the insulating material inner tubal wall, the static passage is led in formation by the wire netting silk;
Three, in the plastic inner pipe outer wrapping layer of forming insulator the metal twine is set, when gas flow through from pipeline, the static in the gas reached the other end joint again by joint to metal twine and goes into ground.
Above-mentioned three kinds of technological schemes though can solve or partly solve the static of leading of insulation air pipe material, still have considerable defective.
Its reason is: 1, add the shaping pipe of copper powder, its bursting pressure value descends, though the adding copper powder is many more, it is strong more to lead electrostatic capacity, and this moment, the bursting pressure value descended also the more; Therefore can cause tubing can't satisfy high pressure, the requirement of ultrahigh pressure Environmental Conditions.2, use the body of built-in metal twine way design, though have the possibility of transporting static on principle, it is subjected to the body moulding process, withholds the restriction of technology and joint and body linking intensity, for the tubing of extrusion moulding, can cause the body moulding to realize; Simultaneously, it is also very difficult to guarantee that joint connects with the high strength of body.3, for adopting in high pressure hose by this structure that the metal twine carries out transporting static is set in plastic inner pipe outer wrapping layer, since the static in the gas by joint to the metal twine, then transport to the other end joint again and go into " ", and the static charge of building up on the inwall can not derive, and therefore the static of leading of this structure does not have good result.
Technology contents
The purpose of the present utility model is intended to: the static that produces in the high-pressure aerated flexible pipe of a kind of effectively transporting is provided, reaches and can eliminate static in the pipe, can guarantee the body pliability again, anti-burst and lead the reliable validity of static.
This high-pressure aerated flexible pipe of leading static is by flexible pipe (4), joint (1), lock sleeve (2) and lead the static member and form and it is characterized in that the described static member of leading is one and is located at the metal spring (3) that flexible pipe (4) inner chamber two ends are connected with joint (1).
This electrostatic high-pressure inflated hose of leading according to above technological scheme design, compare with at present known all kinds of technological schemes, its advantage is: the pliability and the anti-burst that neither change hose material, the spring that very passes through the flexible pipe inner chamber is effectively arranged with the static in the gas flow process again, static high efficient and reliable ground is eliminated by the grounding end of pipeline one end; Do not influence simultaneously the production moulding process of flexible pipe yet.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1. joint 2. lock sleeves 3. metals and tightly spring 4. flexible pipes.
Embodiment
This high-pressure aerated flexible pipe of leading static as shown in the figure, by joint (1), lock sleeve (2), flexible pipe (4) with lead the static member and form, be characterized in that this leads the static member and be one and be located at metal and the tight spring (3) that flexible pipe (4) inner chamber, two ends are connected with joint (1); Constitute a static that produces in the time of to eliminate gas flow in the flexible pipe thus, can keep the flexible compound body of flexible pipe body again.The metal of this body flexible pipe (4) inner chamber and tight spring (3) adopt in actual fabrication and an end connector (1) welding, the other end and joint (1) butt or socket, and form one by the outer lock sleeve (2) of two joints (1) with flexible pipe (4) and lead electrostatic high-pressure inflated hose integral body, both kept the former dirt production. art of flexible pipe, connecting process and material property constant keeps leading the thoroughly reliable of electrostatic efficiency again.
