The good medical X-ray generator pressure-oil tank built-in type expansion valve sealing structure of leakproofness.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of medical X-ray generator pressure-oil tank built-in type expansion valve sealing structure, mainly by case lid component, cross recess group
Screw, expansion valve pressing plate, expansion valve, soket head cap screw, square seal ring and tank body of oil tank is closed to constitute；The case lid component packet
Include the molding aluminium alloy case lid of integrated die-casting and respectively according to design requirement be securely fitted in circuit board below aluminium alloy case lid,
The electronic devices such as high-tension transformer and filament transformer；The expansion valve pressing plate is fixedly mounted on behind expansion valve upper end by ten
Word slot screw assemblies are fixedly mounted below aluminium alloy case lid；The upper edge of the tank body of oil tank is equipped with and square seal ring phase
Matched groove, after square seal ring is packed into groove, case lid component is assemblied in one by soket head cap screw and tank body of oil tank
It rises, entire pressure-oil tank assembly is completed.
The present invention further illustrates, is equipped with the installation to match with expansion valve upper edge below the aluminium alloy case lid
Slot, and it is correspondingly provided with through-hole respectively on aluminium alloy case lid and expansion valve pressing plate；The expansion valve pressing plate is packed into expansion valve
Behind the inside of upper end, the upper edge fixation of expansion valve pressing plate inflated valve is blocked, then the upper edge of expansion valve is packed into aluminium alloy box
The mounting groove for covering lower section passes through through-hole using cross recess screw assemblies and is fixedly connected with aluminium alloy case lid and expansion valve pressing plate, thus
By expansion valve pressing plate by expansion valve together with case lid component fixing assembling.
The present invention further illustrates that the expansion valve is integrally machined molding using nitrile rubber.
The present invention further illustrates that the tank body of oil tank uses the molding aluminium alloy box of integrated die-casting.
In the present invention, the aluminium alloy case lid and cabinet of use are integrated die-casting machine-shaping, solve former cabinet
The heat dissipation problem of the leakage problems existing for steel plate welding fabrication weld seam and cabinet；Expansion valve assembly need to only tighten two cross recesses
Expansion valve and case lid component can be assembled together by screw assemblies, since expansion valve is to be integrally machined molding using nitrile rubber
Leakproofness is good, and having the low characteristics such as economical and practical of wear-resisting, oil resistant price is that this structure provides advantageous conditions, by extraneous ring
The influence of border and machine operation, this structure can ensure that entire pressure-oil tank is in seal shape by expanding with heat and contract with cold for expansion valve
State provides stabilized operating temperature for medical X ray machine generator pressure-oil tank, extends service life of a machine.
Compared with prior art, the features of the present invention:
1. the configuration of the present invention is simple, easy to process and assembly, leakproofness is good, using the molding aluminium alloy case lid of integrated die-casting and
Cabinet solves the leakage and heat dissipation problem of pressure-oil tank, greatly improves the stability of medical X ray machine generator pressure-oil tank.
2. the present invention assembles expansion valve on case lid component by the way of being embedded in, whole fuel tank cabinet can't see swollen
Swollen valve keeps entire pressure-oil tank more beautiful and generous, and expansion valve assembly need to only tighten two cross recess screw assemblies
Expansion valve and case lid component are assembled together, very convenient after-sales service is time saving and energy saving.
