Abstract
The utility model discloses an apparatus for replacing gas containers without interruption. The apparatus is characterized by comprising a first gas supplying valve and a second gas supplying valve; one end of the first gas supplying valve is connected with a first gas supplying container, and the other end of the first gas supplying valve is connected with an opening of a first three-way gas valve; one end of the second gas supplying valve is connected with a second gas supplying container, and the other end of the second gas supplying valve is connected with an opening of a second three-way gas valve; a second opening of each of the first three-way gas valve and the second three-way gas valve is connected with a gas evacuation/absorption pipe; and third openings of the first three-way gas valve and the second three-way gas valve are connected with gas consuming equipment via a gas supplying passage. The interruption will not occur during gas supplying, air is not liable to enter during container replacing, and gas in containers is not liable to leak to pollute the environment.
Description
Technical field
The utility model relates to a kind of uninterrupted replacement gas container device.
Background technique
In a lot of equipment, reactions, process uses pressurization-gas cascade or aerosol container provides gas, as nitrogen, helium, carbon dioxide, argon gas, oxygen, acetylene, hydrogen, hydrogen sulfide, sulfur dioxide, nitrogen oxides etc.The finite capacity of container, gas in a container or finish using, while changing the new container of another one, often need stop supplies gas to switch, use the process need of gas to interrupt, and can entrained air in the process of changing, or discharge gas in the space of changing container, and some gas is inflammable and explosive, or poisonous.
Summary of the invention
To be solved in the utility model is existing apparatus when switching desired gas, in the time of need changing container, and easy entrained air or cause the technical problem of Leakage Gas in system.
In order to solve the problems of the technologies described above, the utility model provides a kind of uninterrupted replacement gas container device, it is characterized in that, comprises air-supplying valve one, air-supplying valve two, one end of air-supplying valve one connects air feed container one, a port of the other end connecting tee air valve one; One end of air-supplying valve two connects air feed container two, a port of the other end connecting tee air valve two; Second port of three-way air valve one, three-way air valve two connects respectively gas emptying/absorption tube; The 3rd port of three-way air valve one, three-way air valve two is connected with gas equipment by air feed gas circuit.
The utility model advantage is compared with prior art:
1, air feed process does not need to interrupt;
2, Renewal process can entrained air;
3, the gas in container can not revealed befouling environment.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, the structural representation of a kind of uninterrupted replacement gas container device providing for the utility model, comprise air-supplying valve 1, air-supplying valve 27, one end of air-supplying valve 1 connects air feed container 1, a port of the other end connecting tee air valve 1; One end of air-supplying valve 27 connects air feed container 29, a port of the other end connecting tee air valve 24; Second port of three-way air valve 1, three-way air valve 24 connects respectively gas emptying/absorption tube 5; The 3rd port of three-way air valve 1, three-way air valve 24 connects after air feed gas circuit 2, by air feed gas circuit 2, is connected with gas equipment 2.
Gas equipment 1 in process of production, according to the utility model being adjusted into following state:
State one (as shown in Figure 2): air-supplying valve 1 is opened, three-way air valve 1 is communicated with air feed gas circuit 2 with air-supplying valve 1, air feed container one 8 supply the first gases; Air-supplying valve 27 is closed, and three-way air valve 24 is closed completely, and air feed container 29 is in closed condition, and air feed container 29 can be dismantled from gas circuit, replace, and does not affect the supply of the first gas;
State two (as shown in Figure 3): air-supplying valve 1 is opened, three-way air valve 1 is communicated with air feed gas circuit 2 with air-supplying valve 1, air feed container one 8 supply the first gases; Air-supplying valve 27 is opened, three-way air valve 24 by air-supplying valve 27 emptying with gas/absorption tube 5 is communicated with, air feed container 29 supply the second gases, the second gas is successively by air-supplying valve 27, three-way air valve 24 exhausts, the emptying air owing to changing air feed container 29 and enter in gas circuit;
State three (as shown in Figure 4): air-supplying valve 1 is opened, three-way air valve 1 is communicated with air feed gas circuit 2 with air-supplying valve 1, air feed container one 8 supply the first gases; Air-supplying valve 27 is opened, and three-way air valve 24 is communicated with air-supplying valve 27 with air feed gas circuit 2, air feed container 29 supply the second gases; It is gas equipment 1 air feed that this kind of state is applicable to two kinds of gases simultaneously;
State four (as shown in Figure 5): air-supplying valve 1 is closed, three-way air valve 1 is closed completely, and air feed container 1 is in closed condition; Air-supplying valve 27 is opened, and three-way air valve 24 is communicated with air feed gas circuit 2 with air-supplying valve 27, air feed container 29 supply the second gases, and now air feed container 1 can be dismantled from gas circuit, change.
