Description

Joint pipe for gas

The utility model relates to a kind of Joint pipe for gas.

Being applied in of coal gas is modern to the utmost for extensive, the thermal source that is produced for by gas firing the time carries out water heating or food heating, gaspipe line all can be installed or purchase the liquefaction coal gas tank for giving coal gas, and installing is taken between liquefaction coal gas tank or gaspipe line and burner (as gas stove, water heater), make the coal gas smooth delivery of power to the burner place, and in view of the restriction of space and kitchen fitting, take over and be designed to soft body mostly.

Traditional adapter, be by the made clear tubular of PVC (PVC) raw material, whole connecting pipe length is extremely long after its moulding, the builder can take the adapter of putting in order volume to installing place, cut suitable length according to the distance between liquefaction coal gas tank or gaspipe line and burner again, with ring the jointing that places liquefaction coal gas tank and burner is enclosed at two ends respectively again, to reach the purpose that coal gas is carried; But be soft pipe body shape for making to take over, just can add plasticizer in its PVC material, but in case after adding plasticizer, its soft spots, tensile strength, creep resistivity, temperature tolerance, chemical rotproofness all can reduce, so end that is connected with the burner interface, promptly can be under long-time too situation near burning things which may cause a fire disaster, cause taking over the phenomenon that the surface produces hot melt, in the course of time, produce breakage even take over, cause coal gas to leak, if the work that the user does not perform maintenance at ordinary times, checks promptly has great danger; And because of the high covering material of its no hardness in surface, therefore very easily broken, can cause equally and take over breakage, lead to dangerous situation by insect bite.

So take over existing dangerous problem at traditional PVC, design later a kind of adapter of avoiding surperficial hot melt phenomenon to produce again, please referring to shown in Figure 7, this adapter 80 is the metal pipes in pipe 81 (promptly being commonly called as coiled pipe) coating PVC by the galvanized iron material, coat pvc material in the surface in the mode of filming again, be set kenel and set firmly a collar 82 again in adapter 80 two ends, during use, the collar 82 that then directly will take over 80 two ends respectively with the liquefaction coal gas tank, the interface of burner closely is connected, coal gas is carried through adapter, can be avoided taking over the phenomenon that when bearing high temperature, produces surface melting around the coating of pipe 81 by metal.

But the adapter of this pattern, though not having the problem of surface melting exists, so has certain thickness around pipe 81 because of its metal, with the general portable type instrument and the work that can't cut arbitrarily, therefore can't cut according to the distance of installing again to construction place, so all be promptly to make specific specification at present in manufacturing works, only 6 chis and two kinds of specifications of 8 chis of finding in the market, and can't adjust under the situation of change in that length is specific in good time, if the distance between liquefaction coal gas tank and burner is more in short-term, have no alternative and also can only select to install the adapter of 6 chis, the result makes and takes in the liquefaction coal gas tank, be rolled between burner, in the case, promptly can influence the transfer efficiency of coal gas, and then influence the using effect of burner, and waste material, but not be a kind of rational design, and pipe is to be made by PVC in it, so after using a period of time, promptly can produce the phenomenon of sclerosis, so that the surface can produce slight crack, and disappointing possibility is arranged.

So from the above, there is impracticable and irrational problem really in two kinds of used Joint pipe for gas at present, and main cause is to provide the structure that can avoid surperficial hot melt and can cut according to installing place situation.

The purpose of this utility model, provide a kind of Joint pipe for gas, this Joint pipe for gas is made up of interior pipe and outer tube, interior pipe is for rubber material and make hollow shape, with the purpose that reaches tight conveying coal gas and prevent to harden, outer tube is then woven by intersection wire netting sheet and is formed, it is pipe outer periphery in directly being coated on, effect with the isolated temperature of tool, can be whole web-like after its moulding and fold, during to installing place, can be according to the distance between liquefaction coal gas tank or gaspipe line and burner, and the adapter of given length does not cut into suitable length, and a joint pipe structure of avoiding the surface to produce hot melt and can suitably cut is provided.

The utility model provides a kind of Joint pipe for gas, this Joint pipe for gas is connected between liquefaction coal gas tank or gaspipe line and burner, and with the interface of beam ring anchor portion, it is characterized in that: this Joint pipe for gas is made up of interior pipe and outer tube, interior pipe is soft rubber body, the outer tube that forms for flexible wire netting sheet interlacing in the interior pipe outside, design makes to take over and possesses the effect that the surface can be born high temperature and can is easy to cut by this.

In addition, in above-mentioned Joint pipe for gas, the design that the wire netting sheet can be single sheet also can be design wiry.

By above technological scheme as can be known, the beneficial effects of the utility model are very obvious.Joint pipe for gas of the present utility model adopts metal outer pipe to coat the design of interior pipe; the adapter of one practicality can be provided; it relies on interior pipe that coal gas is being carried in the space closely; with the problem of avoiding coal gas to leak; and rely on outer tube can make the body surface be subjected to suitable protection; to avoid the disrepair phenomenon that surperficial hot melt caused and the effect of tool oil resistant; and prevent that insect bite is broken; and the utility model also can provide an adapter that is suitable for; the utility model is by the design of outer tube for intersection wire netting sheet; it can be cut easily with the general portative instrument of cutting; therefore the builder can cut adapter according to the actual required distance of installing place; again with easy assembling mode; can finish the group of adapter and establish work, both not have the problem of waste of material, also not have to take over and too reel and influence the problem of coal gas transfer efficiency; so the utility model, can provide a structure that has practicability and applicability concurrently through the improvement of butt tube.

So, promptly possess following effect with overall structure of the present utility model:

(1) size will not limit, and is convenient to construction;

(2) high temperature resistant not spontaneous combustion;

(3) pipe is difficult for sclerosis in;

(4) oil resistant;

(5) insect protected.

Further specify concrete structure of the present utility model and feature below in conjunction with accompanying drawing.
