Description

Refrigerant storage tank of used repeatedly
Technical Field
The utility model belongs to the technical field of the technique of refrigerant storage and specifically relates to a refrigerant storage tank of used repeatedly is related to.
Background
Refrigerant storage tanks are typically provided in current refrigeration systems to accommodate varying evaporator load demands. When the evaporation load is increased, the supply amount is also increased and is replenished by the liquid storage of the liquid storage device; when the load becomes small, the required leaf brightness also becomes small, and the extra liquid is stored in the refrigerant storage tank. And the refrigerant storage tank also plays the effect of liquid seal, prevents that gas from getting into low pressure compressor and producing the liquid hammer phenomenon. Current refrigerant storage tanks are typically provided in a cylindrical shape with a sealing valve mounted on one end of the storage tank. However, the refrigerant storage tank is likely to collide with the sealing valve during transportation, and the sealing valve may be damaged and fail to seal the refrigerant storage tank well, thereby causing leakage of the refrigerant in the refrigerant storage tank. The conventional method is that a protective steel ring is fixedly welded on the upper end face of a refrigerant storage tank and arranged around a sealing valve on the storage tank, the protective steel ring is higher than the sealing valve, and a through groove is formed in the side face of the protective steel ring, so that a pipeline can be conveniently mounted on the sealing valve in the following process. At the moment, the sealing valve is surrounded by the whole protection steel ring, so that the sealing valve is not easy to damage due to collision.
However, for the convenience of transportation, more and more refrigerant storage tanks are developed towards a slimmer trend, the diameter of the refrigerant storage tank is reduced, the size of a sealing valve installed on the upper end surface of the refrigerant storage tank is still unchanged, and if a protection steel ring is still installed, the phenomenon that the diameter of the protection steel ring is similar to that of the refrigerant storage tank or even is larger than that of the refrigerant storage tank easily occurs. Although the protection steel ring still can play the effect of protection sealing valve this moment, nevertheless influence the appearance of whole refrigerant storage tank, be not convenient for transport.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a refrigerant storage tank of used repeatedly, it can make whole refrigerant storage tank be convenient for transport when protecting sealing valve door.
The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:
the utility model provides a refrigerant storage tank of used repeatedly, includes the columniform jar body, and the jar is vertical placing, and the up end of the jar body is the sphere, fixed mounting has sealing valve on the up end of the jar body, the jar body on fixed mounting have a seal receptacle, sealing valve fixed mounting is on the seal receptacle, the seal receptacle is cylindrically, and be provided with the screw thread on the lateral surface of seal receptacle, the up end mounting at the jar body has the protective sheath, the protective sheath is cylindrically, the mounting hole has been seted up to the lower extreme of protective sheath, be provided with the screw thread on the medial surface of mounting hole, sealing valve all is located the seal receptacle upper surface at seal receptacle upper surface place planar projection, the diameter of mounting hole equals with the diameter of seal receptacle, the up end of protective sheath sets to the hemisphere, has seted up the air vent on the side of.
