Abstract
The utility model relates to a flexible pipe, particularly a metal flexible pipe which comprises a corrugated pipe, a net cover and connectors, wherein the corrugated pipe is arranged in the flexible pipe; the net cover is sleeved outside of the corrugated pipe; the connectors are arranged at two ends of the flexible pipe; the corrugated pipe, the net cover and the connectors are made of metal; an elastic part for sealing is arranged in the connectors; and one end or two ends of the connectors is provided with a valve structure. The flexible pipe having valve is convenient to repair. Compared with the similar pipes, the flexible pipe having valve has obvious advantages and has lower cost, relative to a singly arranging valve.
Description
Technical field
The utility model relates to a kind of flexible pipe, especially comprises the metallic hose of bellows, net and joint.
Background technique
Metallic hose in modern industry in occupation of extremely important position.It had both had with the same flexible of sebific duct; Simultaneously, have withstand voltage, high temperature resistant, low temperature resistant, ageing-resistant, decay resistance again.In 1855, Germany delivered the patent of making bellows at first.It is to utilize the principle of existing at that time manufacturing jewellery to make bellows.After 30 years, the ELevavasseur of France and German HWitzenmann cooperation research and development novel metal bellows have obtained the patent right of France with Germany in August, 1885.This is to be the metal tape trachea that coiling forms on special device of s shape with the cross section, and they fill out the seaming place of pad at adjacent two circles with rubber tape, cotton fabric or asbestos rope, are beneficial to the sealing of bellows inner chamber.
In 1894, the structure of this class bellows was improved; People press different-diameter with two metal tapes, reel round about.Like this, metal tape is issued to mutual balance in stress, has overcome the disadvantage of exploitation expansion certainly.
In 1929, on the structure of bellows, carried out important improvement again, people have made whole bellows with steel and copper-zinc alloy material, the i.e. bellows made from tubing seamless or that weld seam is arranged, its relies on the resiliently deformable of corrugated sidewalls to keep certain compressibility or tensility; Simultaneously, guarantee sealing reliably.From the significance of bellows as the metallic hose body, the development of metal bellows also just means the development of metallic hose.
Subsequently, people are materials such as rubber, plastic tube or nylon on the bellows outer surface coats, the net that armouring has wire or metal tape to constitute, the various joint forms of conversion are for the difference that adapts under the various service conditions requires to have created various forms of metallic hoses.Yet there is a problem in existing metallic hose, is exactly maintenance inconvenience, when running into line clogging, usually needs to close just easy access of main valve.
The model utility content
The purpose of this utility model is to be to provide a kind of can address the above problem the flexible pipe of the band valve of easy access.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of flexible pipe with valve, comprise the bellows that is positioned at flexible pipe inside, be coated on the net outside the bellows and the joint at flexible pipe two ends, described bellows, net and joint are made of metal, be provided for the elastic member that seals among the joint, it is characterized in that the one or both ends of described joint are provided with valve mechanism.
Preferably, valve mechanism is a ball valve.
Preferably, the Spin Control portion of valve mechanism forms a recessed word or quincunx.
Because the one or both ends at the joint of metallic hose in the utility model are provided with valve mechanism, overhaul very conveniently, compare with existing similar flexible pipe, have remarkable advantages, with respect to independent configuration valve, cost is lower.
Description of drawings
Fig. 1 is the hose construction schematic representation of the utility model band valve;
Fig. 2 is the plan view of the flexible pipe of the utility model band valve.
Embodiment
Metallic hose is made of bellows, net and joint three parts substantially.Bellows is the body of metallic hose, plays a part flexible; Net plays a part to strengthen, shielding; Joint plays a part connection.To different usage requirements, interconnective mode has nothing in common with each other between them: bellows, net are connected with the form of joint three parts with welding, are called welding type; Form with mechanical clamping connects, and is called the mechanical clamp stationary; Remove this, go back the above-mentioned two kinds of method couplings of handlebar, be called hybrid.Net is woven in certain sequence by cross one another some strands of wires or some metal tapes that splits and forms, and is sleeved on the outer surface of metal bellows with the angle of regulation, plays a part to strengthen and shielding.The effect of joint at first is that net and bellows are connected as one, and simultaneously, joint is again metallic hose and metallic hose or other pipe fitting, the joining parts of equipment.Its assurance medium is normally worked in pipe-line system.The material of joint is identical with the material of bellows, net usually, how based on stainless steel.For reducing production costs, the bigger metallic hose of some latus rectums is when carrying the not strong or non-corrosive medium of corrosivity, and joint can be made of carbon steel.
As depicted in figs. 1 and 2, the flexible pipe of a kind of preferred implementation band valve of the present utility model, comprise the bellows (not shown) that is positioned at flexible pipe inside, be coated on the net 3 outside the bellows and the joint 1 and 4 at flexible pipe two ends, described bellows, net and joint are made of metal, be provided for the elastic member that seals among the joint, an end of present embodiment middle joint 1 is provided with valve mechanism 2.
Claims (3)
1. be with the flexible pipe of valve, comprise the bellows that is positioned at flexible pipe inside, be coated on the net outside the bellows and the joint at flexible pipe two ends, described bellows, net and joint are made of metal, be provided with the elastic member that is used to seal among the joint, it is characterized in that the one or both ends of described joint are formed with valve mechanism.
2. flexible pipe according to claim 1 is characterized in that described valve mechanism is a ball valve.
3. flexible pipe according to claim 1 and 2 is characterized in that the Spin Control portion of described valve mechanism forms a recessed word or quincunx.
