Abstract
The utility model provides a device for recovering and refilling residual liquid of liquefied petroleum gas, which relates to a close-circuited transmission device of liquid fuel. The device for recovering and refilling residual liquid of liquefied petroleum gas is composed of a portable miniature liquid pump, a liquid valve which is connected by a flexible pressure-resistant pipe on an inlet and an outlet of the liquid pump, gas valves, and a three way of a flexible joint. A pressure gauge is arranged between two gas valves. The device for recovering and refilling residual liquid of liquefied petroleum gas can make the residual liquid of the liquefied petroleum gas in a cylinder of a user directly pumped and filled to a special cylinder of the fuel of the residual liquid, and the device for recovering and refilling residual liquid of liquefied petroleum gas creates conditions for recovering and utilizing the fuel of the residual liquid to the user. The utility model has the advantages of simple structure, safe and convenient operation, and no environmental pollution.
Description
The utility model relates to the closed circuit transmitting set of a kind of liquid fuel.
Its main component of LPG (liquefied petroleum gas) residual liquid is the hydro carbons that boiling point is higher, calorific value is higher, is difficult to vaporization and becomes raffinate and go out of use in steel cylinder, and this not only wastes resource, and bring hidden danger can for environment and safety, is a difficult problem in the liquefied petroleum gas management.The someone has proposed atomize easy, the safe, practical technology of directly burning of LPG (liquefied petroleum gas) residual liquid is utilized scheme now, and it comprises atomization combustion stove and accessory and raffinate fuel special cylinder.But, how to reclaim for the raffinate in domestic consumer's the liquefied petroleum ga steel cylinder? steel cylinder can only be delivered to large-scale liquefied petroleum gas container field at present, utilize the industrialization pump to get device and be drawn in the big storage tank of raffinate.And then give raffinate fuel special cylinder from big storage tank can.
The purpose of this utility model, the raffinate in domestic consumer's steel cylinder directly can being taken out of providing that a kind of and above-mentioned residual liquid scheme matches are irritated easy, the safe and reliable raffinate that is recovered in the raffinate fuel special cylinder and are reclaimed pumping and filling device.
The technical solution that realizes above-mentioned purpose is: adopt a small-sized liquid pump, import and export at liquid pump respectively connect a liquid valve with the flexible pressure-resistant pipe respectively, and two liquid valves are connected on the interface of two threeways, another interface of two threeways be can be matched with cylinder valve the screw thread flexible joint, the interface that also has of two threeways connects a gas valve respectively, is connected with the flexible pressure-resistant pipe between two gas valves.
Accompanying drawing is the utility model general structure schematic representation.
The utility model is described in further detail with embodiment in conjunction with the accompanying drawings.
The utility model in use, as long as the flexible joint of the valve combination threeway that the liquid pump import is connected is connected with waiting the valve of taking out the raffinate steel cylinder; Simultaneously, the flexible joint of the valve combination threeway that will be connected with the liquid pump outlet is connected with the inlet valve of raffinate fuel special cylinder.Then, open the valve of two steel cylinders, open and be connected in the air valve of waiting to take out the raffinate steel cylinder, observe air pressure, close this air valve; Unlatching is connected in the air valve of raffinate fuel special cylinder, observes air pressure, if the air pressure of waiting to take out in the raffinate steel cylinder is higher than the interior air pressure of raffinate fuel special cylinder, favourable the carrying out of taking out filling; If opposite, should open the air valve of waiting to take out the raffinate steel cylinder, make the air pressure in two steel cylinders gang up balance, then, close two air valves, open two liquid valves.Inversion waits to take out the raffinate steel cylinder, and the starting liquid pump is taken out filling.Take out filling and finish, close valve separately on the steel cylinder, close all valves of two valve combination threeways, drawing liquid and storage filling process are finished, and dismantle this device.Liquids and gases in sebific duct and the liquid pump all are sealed therebetween, can not leak.
The utility model is simple in structure, and is safe in utilization, reliable, convenient, free from environmental pollution.Using this device can call and directly extract LPG cylinder for the user.
