Abstract
The utility model discloses a pressure controller takes over connection structure, the conical surface constitutes the annular arch with the lower conical surface or arc surface in the adoption provides the location for being connected the body, can directly improve on original mould, but produce one shot forming when taking over, is suitable for batch production, the conical surface angle that goes up the conical surface can provide sufficient welding filler space, and the solder can fully fill up the connection position during welding, and the location is accurate and the welding is reliable, and welding strength is high, the connecting pipe position is measure -alike with extension section two parts diameter in the linkage segment of the protruding both sides of circle shape, has reduced material consumption, has reduced product cost, has improved the welding quality of pressure controller with system's pipeline, and the commonality is strong, and welding position is simple, and it is convenient to connect, production efficiency height, low cost.
Description
Technical field
The utility model is related to a kind of pressure controller adapter attachment structure, is applied particularly to all kinds of household electrical appliance, pressure
In the system pipeline connection of control device etc..
Background technology
In prior art, positioning, welding inconvenience when the system pipeline such as pressure switch and air-conditioning, control device is connected, and have
Not can manufacture；It is general that pressure switch and system pipeline connectivity problem are solved using special-shaped interface shape, but deposit
In various defects, annulus, reducing step, the outside salient point of tube wall etc. are positioned for example with increasing at interface position, and setting circle ring
Can stop that solder causes welding leakage into connecting portion in welding, weld strength is inadequate, using reducing ledge structure cost
High, the structure processing of the outside salient point of tube wall is relatively difficult, particularly difficult when caliber size is less, is not suitable for batch production；Also
There is a kind of structure of employing straight tube another setting position after connecting, weld size precision is not high, and the production efficiency of pressure switch is relatively low.
The content of the invention
Technical problem to be solved in the utility model is to provide the pressure controller of a kind of accurate positioning, convenient welding
Adapter attachment structure, and weld strength reliability, production efficiency is high, with low cost.
Pressure controller adapter attachment structure of the present utility model, including connection pipe body, it is characterised in that：Connection pipe body
Connecting portion is provided with annular protrusion, and the upper convex surface is the conical surface, and lower surface is arc surface；
To be welded to connect face, the frustoconical bevel angle of upper surface can provide enough weld filler spaces for the upper surface；
The linkage section that the connection pipe body is located at annular protrusion both sides is identical with extension two parts diameter dimension.
Pressure controller adapter attachment structure of the present utility model, adopts the annular protrusion with cone-shaped upper surface to connect
Adapter body provides positioning, and lower surface is the conical surface or arc surface, can be directly improved on original mould, can be once during production adapter
Shaping, it is adaptable to produce in batches；The frustoconical bevel angle of upper surface can provide enough weld filler spaces, and solder can during welding
Connecting portion, accurate positioning and welding reliability are adequately filled up, weld strength is high；Connection pipe body is located at the part of annular protrusion both sides
It is equivalently-sized, material consumption is reduced, product cost is reduced, the welding quality of pressure controller and system pipeline is improve,
Highly versatile, and weld positioning simply, easy to connect, production efficiency is high, with low cost.
Description of the drawings
Fig. 1～Fig. 4 is the pressure controller adapter attachment structure planar structure schematic diagram of prior art；
Fig. 5 is the pressure controller adapter attachment structure planar structure schematic diagram of the utility model embodiment.
Specific embodiment
As illustrated, a kind of pressure controller adapter attachment structure, adopts the annular protrusion with cone-shaped upper surface 3 to connect
Adapter body provides positioning, and lower surface 4 is arc surface, can be directly improved on original mould, can be once-forming during production adapter,
It is suitable for the batch production taken over, is also suitable for the batch production of pressure switch；Upper surface is to be welded to connect face, frustoconical bevel angle energy
Enough weld filler spaces are enough provided, solder can adequately fill up connecting portion, accurate positioning and welding reliability, weldering during welding
Connect intensity high；The linkage section 1 that connection pipe body is located at annular protrusion both sides is identical with two parts diameter dimension of extension 2, reduces
Material consumption, reduces product cost；On the premise of production pressure controller or pressure switch items cost is not improved, can
Pressure controller is reduced when welding with system pipeline to welding the skill set requirements of operative employee, and improves pressure controller and system
The welding quality of pipeline, reduces leakage and the weld strength problem occurred because of welding, improves overall mass, reduces so as to reach
The purpose of cost, and weld positioning simply, highly versatile is easy to connect, and production efficiency is high, with low cost.
Pressure controller adapter attachment structure of the present utility model, it is adaptable to the refrigeration unit such as all kinds of air-conditionings, ice machine with
And the various pipelines of the equipment such as various use heat pumps, oil pump, air pump, instrument, the pressure controller of machinery and system above connect
Connect, production adapter mould can be directly improved on original mould, can be once-forming during production adapter, production efficiency is high；In pressure
In the finished product production process of force controller, all tool fixtures can adopt the first form for currently using, be not required in addition
Make；For the system vendor using pressure controller, reduce to welding the skill set requirements of operative employee, and reduce because of weldering
The leakage for connecing and occurring and weld strength problem, improve the weld strength of pressure controller and system pipeline, reduce whole machine
Production cost.
