Abstract
The utility model discloses a kind of bellows preventing welding fluid from leaking, comprise bellows, bellows periphery is coated with net, is connected with adapter inside described bellows axial end portion, and adapter bottom is provided with the snap ring of the bellows inwall that is connected together.The utility model effectively prevents the welding fluid formed after weld-ring fusing in welding process by Snap ring structure, spill between adapter and bellows, improves the weld strength between adapter and bellows.
Description
Technical field
The utility model relates to a kind of bellows, prevents the bellows that welding fluid leaks specifically.
Background technique
Bellows is a kind of housing with the cylinder-shaped thin wall wrinkle of multiple transverse wave, and bellows has elasticity, can produce all multiactions such as displacement under pressure, axial force, transverse force or moment of flexure.Bellows tube wall is thinner, and sensitivity is higher, and measuring range is that tens of handkerchief is to tens of MPa.Due to all multi-link advantage of bellows, the use amount of current bellows is caused to increase year by year, but corrugated tube end uses and is welded to connect in the process of connecting tubes, due to the mobility of welding fluid often cause welding fluid under let out, the technological deficiencies such as the welding fastness caused is poor.Under the prerequisite guaranteeing anti-pressure ability, how to prevent from welding fluid from leaking becoming the technical problem that those skilled in the art are badly in need of overcoming.
The Chinese utility model patent patent No. 200720302931.2 discloses a kind of double-wall corrugated pipe, and it comprises bellows, and described bellows is double-wall corrugated pipe, and the enlarging circle in the enlarging of its double-wall corrugated pipe is the lenticular ring stiffener of step.This kind of bellows do not mention how to prevent welding fluid under let out aspect correlation technique prompting.
Summary of the invention
The utility model provides that a kind of structure is simple, long service life, bearing capacity strong, low cost of manufacture, be suitable for the bellows preventing welding fluid from leaking of refrigerant recovering industry.
A kind of bellows preventing welding fluid from leaking, comprise bellows, bellows periphery is coated with net, adapter is connected with inside described bellows axial end portion, adapter bottom is provided with the snap ring of the bellows inwall that is connected together, Snap ring structure effectively prevents the welding fluid formed after weld-ring fusing in welding process, spills between adapter and bellows, improves the weld strength between adapter and bellows.
Trim ring is provided with outside axial end portion as the preferred described net of structure; Net end end face is concordant with the axial end portion end face of trim ring and bellows, and is connected with the end of net outside bellows axial end portion.This kind of end face flush configuration evades traditional bellows in the connection, net end is often not cognitive in the technology that the axial end portion end face of bellows is concordant, this kind is not also have the basis of link to be formed outside end end face based on conventional construction net in the technology cognition that the axial end portion end face of bellows is concordant, and the utility model to be the end end face of net concordant with the axial end portion end face of trim ring and bellows, be not connected with other links, while reducing manufacture cost, improve aesthetics and the usability of product.Bellows is by connecting tubes and the trim ring respectively of both sides inside and outside bellows axial end portion, other pipelines are connected by adapter, and trim ring thoroughly improves the bearing capacity of corrugated tube end, the Placement of this kind of bellows is under the prerequisite taking into account bearing capacity and switching performance, because component are few, greatly reduce manufacture cost.
Bellows described in preferred as structure, trim ring are stainless steel material, improve the compressive strength of bellows.Adapter material is red copper, the chemical property quite stable of copper, is not easily corroded.The intensity of copper pipe is more much higher than plastic tube, can bear sizable pressure; And the steel pipe of ratio, copper pipe has again good toughness, stronger frost heave and impact under also not crack, do not fracture.The fusing point of copper is high; even if the medium temperature of transmission is up to 200 DEG C; also can work on long-term safety ground; there is good permeability resistance; in using process; its surface energy forms one deck compact structure, not by the protective film of medium dissolves, no matter be that grease, carbohydrate, bacterium and virus, harmful liquid, oxygen or ultraviolet all through it and then can not corrode tube wall.
The utility model effectively prevents the welding fluid formed after weld-ring fusing in welding process by Snap ring structure, spill between adapter and bellows, improves the weld strength between adapter and bellows.
Accompanying drawing explanation
Fig. 1 is that the bellows master that the utility model prevents welding fluid from leaking looks sectional structure schematic diagram.
Embodiment
See a kind of bellows preventing welding fluid from leaking of accompanying drawing 1 the utility model, comprise bellows 4, bellows 4 periphery is coated with net 5, is connected with adapter 2 inside bellows 4 axial end portion, is provided with the snap ring 1 of the bellows inwall that is connected together bottom adapter 2.
Be provided with trim ring 3 outside axial end portion as the preferred net 5 of structure, net 5 end end face is concordant with the axial end portion end face of trim ring 3 and bellows, and is connected with the end of net 5 outside bellows axial end portion.
In order to the overall performance bellows 4, the trim ring 3 that improve bellows are stainless steel material.Adapter 2 material is red copper.
