Description
Technical field
The utility model relates to the outer boiling heat transfer visual testing device of a kind of high-pressure working medium pipe.
Background technology
Flooded evaporator in the refrigeration system is a horizontal shell and tube type, in the cylindrical shell of flooded evaporator, fills liquid working substance, and liquid contacts with heating surface well, and boiling heat transfer coefficient is high.But present CO
2Evaporator etc. high-pressure working medium is too high owing to shell pressure, and the system design difficulty is big, still adopts dry type.Therefore, CO
2Efficient etc. the high-pressure working medium system also needs to improve, and using the alternative original dry evaporator of flooded evaporator instead is one of approach, is devoted to CO
2The research of outside the full-liquid type system pipes, evaporating boiling phenomenon etc. high-pressure working medium becomes current focus, and how better sighting tube evaporates the key that boiling phenomenon is this technology outward.Because CO
2Higher Deng the evaporation operating pressure, sealing and visual need carrying out simultaneously.In the outer boiling heat transfer visual testing device of present high-pressure refrigerant pipe; The visual observation window is the circular glass pipeline that is installed in the housing middle part; Because circular glass pipeline pressure-bearing is not enough,, can cause the circular glass pipe to observe vision deviation for the withstand voltage thickness that needs to increase glass tube walls.Simultaneously, circular glass pipeline butt-end packing undercapacity, stay-bolt is oversize, and circular glass pipe end face seal discontinuity causes face leakage easily, also causes explosion under the glass tube high pressure easily.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of bearing capacity strong, and the butt-end packing performance is good, and the outer boiling heat transfer visual testing device of high-pressure working medium pipe of deviation does not appear in the test effect.
The utility model is realized through following technical proposals:
The outer boiling heat transfer visual testing device of a kind of high-pressure working medium pipe; Comprise tubulose Stainless Steel Shell and boiling heat transfer copper pipe, said lower housing portion and the corresponding position of refrigerating medium entrance point are provided with the high-pressure refrigerant import, and said housing upper end exports a corresponding side with refrigerating medium and is provided with the high-pressure refrigerant outlet; Said housing two ends are welded with end socket respectively; Be welded with closure nut on each end socket, said boiling heat transfer copper pipe is installed in said enclosure interior and passes the end socket at housing two ends, the closure stud that the two ends of said boiling heat transfer copper pipe are with the band central through hole respectively and are threaded with closure nut; Between each closure stud and the closure nut gasket seal is installed; It is characterized in that said housing top and bottom are respectively arranged with observation panel, each observation panel place is welded with the adapter of passing through mutually with said housing; Be welded with joint flange in the said adapter; Said joint flange is provided with the view window mounting groove, and circular quartz glass view window is installed in the said view window mounting groove, on the said view window mounting flange is installed; Said mounting flange is fixedly connected with said joint flange through bolt, between said quartz glass view window and the joint flange, be respectively arranged with sealing gasket between quartz glass view window and the mounting flange.
Gasket seal between said closure stud and the closure nut is a polytetrafluoroethylmaterial material, and the sealing gasket between view window and joint flange, view window and the mounting flange is a polytetrafluoroethylmaterial material.
The utlity model has following technique effect:
1, the view window in the outer boiling heat transfer visual testing device of the high-pressure working medium pipe of the utility model adopts circular dull and stereotyped quartz glass; Bearing capacity is strong; Avoided circular glass duct type view window bearing capacity defect of insufficient; Overcome the deviation of circular glass to visual testing simultaneously, the test effect truly reflects the situation of boiling in ducts.
2, the outer boiling heat transfer visual testing device of the high-pressure working medium pipe of the utility model directly is installed in the view window sealing on the housing through sealing gasket and two flanges; The coupling bolt contraction in length; And control is to the snap-in force of quartz glass easily; Avoid the explosion on the contrary of glass discontinuity, and then realize sealing easily, and sealing property is better.
