Abstract
The utility model relates to a metal bellows for a gas burning appliance. One end of a connecting pipe is a flat port and the other end is a bell-and-spigot port. The flat port is mainly characterizedin that a boss is arranged on a round pipe integrated with the bellows and is used for placing a sealing gasket. The bell-and-spigot port is mainly characterized in that the top of the round pipe integrated with the bellows is a horn-like bell. The two ends of the connecting pipe can be directly connected with the gas burning appliance and the utility model has the advantages that the cost is saved, the safety is reliable, the gas is not apt to leak, the installation is easy and the service life is long. The connecting pipe can be used for the connection between the gas burning appliances such as gas stoves, water heaters and the like and between the gas burning appliance and the gas pipe.
Description
Technical field
The utility model relates to and a kind ofly is used between Gas appliances such as petroleum gas, liquid gas, coal gas and rock gas connecting or connecting tube that Gas appliance is connected with gas pipeline, relates in particular to a kind of connecting tube of metal bellow type.
Background technique
The gas transmission connecting pipe that is used at present to connect Gas appliance in the society adopts rubber pipe more, the rubber pipe corrosion-resistant, and easy season cracking, working life is short, and leakage phenomenon takes place easily.A lot of carbon monoxide poisoning and gas explosion incidents on fire that cause because of the rubber pipe gas leakage have taken place in the whole nation.
Summary of the invention
The purpose of this utility model is in order to solve present Gas appliance connecting tube corrosion-resistant, the problem of leakage to take place easily, a kind of connecting tube of metal bellow type being provided.And connecting tube two end interfaces adopt multi-form, can directly Gas appliance be linked together.
The technical solution of the utility model that realizes this purpose is:
The utility model connecting tube, its middle part is a bellows, and connecting tube one end is a balance pressure type interface, and the other end is a spigot and socket type interface.The structure of balance pressure type interface is: in the end of described this end of connecting tube, with bellows be that the pipe of one is provided with a boss that is used to place gasket seal, be with an internal threaded nut on the described pipe.The structure of spigot and socket type interface is: in the end of described this other end of connecting tube, with bellows be that the pipe top of one is a tubaeform mouth that rises, rise and be placed with a collar-shaped seal ring on the mouth, on described pipe, be with mouthful nut that rises, and have an exterior nut cap to be screwed on the described mouthful nut that rises in addition.
The used Stainless Steel Tube corrosion resistance of the utility model is strong, and good seal performance has overcome the defective of easy leakage, has prolonged the working life of connecting tube greatly.This connecting tube one end is the balance pressure type interface, and the other end is the spigot and socket type interface, and two ends can directly join with gas pipeline or other Gas appliance and need not dispose transition joint.The utlity model has and save that cost, safe and reliable, combustion gas are difficult for leaking, pliability is convenient to by force to install and the advantage of long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 bellows, 2 pads, 3 boss, 4 internal threaded nut, 5 mouths that rise, 6 collar-shaped seal rings, the 7 mouthful nuts that rise, 8 exterior nut caps, 9 press mouthful, 10 clads.
Embodiment
Referring to Fig. 1, the utility model connecting tube is a metal bellows 1, and bellows 1 can be made with stainless steel.Connecting tube one end is a balance pressure type interface, and the other end is a spigot and socket type interface.Balance pressure type interface and spigot and socket type interface do not have transverse weld with being connected of 1 of bellows, have improved security of products.Be coated with the clad 10 of one deck PVC transparent plastic at bellows 1, this clad 10 can effectively be avoided the erosion of condiment such as vinegar to body, is convenient to again keep a public place clean, and can prolong the life-span of connecting tube.Respectively there is one to press mouth 9 between balance pressure type interface and spigot and socket type interface and the bellows 1, presses the two ends of mouth 9 that clad 10 is pressed on the pipe of bellows 1 end.Add man-hour, earlier the incision position at the two ends of the clad 10 of PVC is put the heat-shrink tube of the about 10-15mm of a segment length respectively, the heating aftershrinkage wraps tightly the pipe of bellows 1 end, so that clad 10 centres of bellows 1 and PVC are in sealing states.After this operation is finished, will press mouthful 9 two ends compactings on the pipe of bellows 1 end, to be fixed into one again.
Balance pressure type interface one end and pressure thereof mouthful 9 employing half section techniques of painting among Fig. 1, the complete section technique of painting is adopted in spigot and socket type interface end.The structure of balance pressure type interface is: in the end of connecting tube one end, with bellows be that the pipe of one is provided with a boss 3 that is used to place gasket seal 2, be with an internal threaded nut 4 on the described pipe, the bottom diameter of internal threaded nut 4 is greater than the pipe external diameter and less than the external diameter of boss 3, so that internal threaded nut 4 can not be taken out from port.The structure of spigot and socket type interface is: in the end of the connecting tube the other end, with bellows be that the pipe top of one is one and tubaeformly rises mouthfuls 5, rising is placed with a collar-shaped seal ring 6 on mouthfuls 5.Also be with mouthful nut 7 that rises on the pipe of this end, mouthful nut 7 of rising is the outside thread nut, and its internal diameter is greater than the pipe external diameter of bellows 1 end and less than rising by mouthfuls 5 bell-mouthed bore.Like this, mouthful nut 7 that rises can slide on the pipe of bellows 1 end, but mouthfuls 5 the horn mouth of being risen stops, can not take off from pipe.And other has an exterior nut cap 8 to be screwed on the described mouthful nut 7 that rises.When connecting Green's joint, outer tube directly inserts, and locking exterior nut cap 8 is pressed on outer tube in the mouth 5 that rises by collar-shaped seal ring 6, plays the effect of firm connection and sealing.
The utility model be applied between Gas appliances such as combustion gas gas kitchen, water heater and Gas appliance and gas pipeline between be connected.
