Coolant solo valve and coolant explosion-proof tank thereof

Abstract

The invention relates to a refrigerant one-way valve and a refrigerant explosion proof tank thereof, which belongs to the refrigerant storage apparatus technical field. A seal sphere is correspondingly arranged at a second tapered bore of a valve seat, a seal ring is arranged on the outer wall of a core body corresponding to a first tapered bore, and threads matching the valve seat are arranged on the outer wall of a core cap capable of rotating relatively between the valve core and the core cap; a core bar passes through the core cap and the core body, a limiting mechanism is arranged on the upper end of the core bar, and a reset spring encases the middle part of the core bar; the lower end of the reset spring is in contact with a tapered positioning hole of the core body, and the upper end of the reset spring is in contact with a snap ring; a core seat is arranged on the lower end of the core bar, and the upper end of the core seat is provided with a seal gasket which has an outside diameter at least larger than the diameter of a lower cylindrical hole of the core body; the valve bar is provided with an interlocking truncated cone corresponding to the upper end face of the seal gasket, and the outside diameter of the interlocking truncated cone is larger than the aperture diameter of the inner hole of the seal gasket. The refrigerant can be stored hermetically for next use when the refrigerant is not used up for the first time, thereby reducing waste of refrigerant and environmental pollution.

Description

technical field [0001] The invention relates to a refrigerant one-way valve and a refrigerant explosion-proof tank thereof, belonging to the technical field of refrigerant storage devices. technical background [0002] A two-piece refrigerant tank including a tank top, a tank body and a tank bottom (notice number: CN2427449Y). The tank top, tank body, and tank bottom are made of two pieces of material and then connected. Rolled seal connection with tank bottom or tank top. When the above-mentioned refrigerant tank is opened for use, the refrigerant stored in the refrigerant tank must be used up at one time, and the refrigerant tank cannot be closed again, resulting in a waste of refrigerant and pollution to the environment. Contents of the invention [0003] The object of the present invention is to provide a refrigerant one-way valve and its refrigerant explosion-proof tank that can be sealed for continued use when the refrigerant is not used up at one time, which reduce...
