Description
Technical field
Patent of the present invention relates to a kind of mortor operated valve, is the magnetic force producing by electromagnetic coil, realizes spool relative to the moving of valve core case, and to reach, controls uninterrupted object, is particularly suitable for air-conditioning refrigeration system.
Background technique
Mortor operated valve is a kind of components and parts of Electromagnetic Control, is used in the break-make of control media in industrial control system or the parameters such as flow of adjustment medium, thereby realizes the control of expection.As in refrigeration system, a kind of as mortor operated valve, electric expansion valve, for regulating the refrigerating capacity into vaporizer, is supplied with the refrigeration agent of optimal dose to vaporizer, guarantee the stable operation of refrigeration system.The electronic expansion valve structure of prior art, as disclosed a kind of electric expansion valve that is adapted to heavy caliber commercial refrigerating device as described in Figure 8 in Japan Patent (JP2009-162369).This electric expansion valve comprise the cover body 20 of semiclosed tubbiness ', be placed in the coil component 40 as stator component of cover body 20 ' outer ', with be placed in the rotor part 30 of cover body 20 ' inside ', with the spool 50 of rotor part 30 ' be connected ', and with cover body 20 ' airtight valve body parts being connected 10 ', valve body parts comprise the valve seat 12 of tubular ', valve core case 11 ', the first connecting tube 13 ', the second connecting tube 14 ', valve seat 12 ' with cover body 20 ' welding form an airtight chamber 60 ', the first connecting tube 13 ' with the second connecting tube 14 ' with chamber 60 ' airtight communicating.
Owing to being used in heavy caliber commercial refrigerating device, compare with common electronic expansion valve structure, need the volume of chamber relatively large, so valve seat adopts tube-like thin-wall structure more, and the first connecting tube 13 of mortor operated valve ' with valve seat 12 ' directly insertion is welded, left and right is without supporting part, strength of connection only depend on the first connecting tube 13 ' with valve seat 12 ' the adhesive strength of the very thin border annulus weld seam of material thickness and cooperation place guarantee, the welded seal of this welding line structure is not ideal enough, and adhesive strength is reliable not.Be installed in system, through vibration and highpressure, impact, exist and come off and the hidden danger of leaking, in addition, during welding, need use tool locating.Prior art scheme, for improving adhesive strength, has to improve the material thickness of valve seat.Seat material thickening, the cost of raw material improves on the one hand, requires on the other hand the equipment tonnage of punch process high, and equipment investment is large, cost is high.
Equally, valve seat core is combined with valve seat, also there is the poor defect of weldering knotting strength, when the second connecting tube is with entering logical high pressure, the first connecting tube passes into low pressure, and it is too high that valve seat and cover body form airtight chamber, and valve seat core is subject to downward atmospheric pressure, if solder bond intensity is slightly poor, exists and come off and the hidden danger of leaking.In addition, two weld-rings relatively far apart, need to be placed in the welding part of the welding part of valve seat core and valve seat and the first connecting tube and valve seat, and welding procedure is complicated.
So, in the especially large capacity business-use refrigrating system of refrigeration system, use in the mortor operated valve structure of thin-walled material as valve seat, how to solve the weld strength problem between connecting tube and valve seat, simplifying technique and eliminate valve body and leak hidden danger, is the problem that those skilled in the art need to solve.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is a kind of mortor operated valve that can be applicable to large capacity business-use refrigrating system of design, make to realize good welding between the valve seat of thin-walled type tubular and connecting tube and valve core case airtight, the technique that simplifies the operation, has improved working life and the functional reliability of valve.
For this reason, the present invention proposes a kind of mortor operated valve, this mortor operated valve comprises cover body, spool and valve body parts, described valve body parts comprises valve core case, valve seat, the first connecting tube, the second connecting tube, it is characterized in that, described valve core case has with described valve seat simultaneously and welds affixed periphery and Transverse plane;
