Abstract
Low temperature cylinder vacuum leak detector, including vacuum pump, cold-trap and vacuum distribution pipe, vacuum pump is connected with vacuum distribution pipe, several suction inlets are set in vacuum distribution pipe, cold-trap is connected by corrugated stainless steel tubing with suction inlet, and several fast interfaces of cold-trap outlet setting are connected with low temperature cylinder to be detected.The utility model is by being arranged cold-trap in vacuum pump and low temperature cylinder to be detected, it not only can be improved and vacuumize efficiency, and reduce gas cylinder temperature, the time for taking out one group of gas cylinder is fallen to 15 minutes by pervious two hours, the time of replacement vacuum oil was changed by two days one to be extended for 25 days one changing, production efficiency is greatly improved, testing cost is reduced.
Description
Technical field
The utility model relates to gas cylinder safely detection device technical fields, and in particular to a kind of low temperature cylinder vacuum leak hunting dress
It sets.
Background technique
It needs to carry out finished product leak detection before low temperature cylinder factory, during leak detection, since gas cylinder is to have welded bottle body circumferential weld
After carry out leak detection work, in gas cylinder temperature it is higher to cause vacuum pump to vacuumize extremely difficult, taking out one group of bottle, four low temperature cylinders needs
Two more than hour are wanted, and a raising that vacuum oil causes testing cost will be changed within two days.
The device of harmful components partial pressure in gas and vapour mixture is reduced with method physically or chemically trap, cold-trap
It is the trap of the captured gas in a manner of condensing on cooling surface, cold-trap is placed between vacuum tank and pump, not only be can be used and is made a return journey
Except the moisture in vacuum, the temperature of associated devices can also be reduced.
Summary of the invention
The utility model provides a kind of low temperature cylinder vacuum leak detector, warm in gas cylinder of the existing technology to solve
Spend the higher problem for causing vacuum pump to vacuumize difficulty.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of low temperature cylinder vacuum leak detector, including vacuum pump, cold-trap and vacuum distribution pipe, vacuum pump and vacuum are distributed
Pipe is connected, and several suction inlets are arranged in vacuum distribution pipe, and cold-trap is connected by corrugated stainless steel tubing with suction inlet, and cold-trap outlet is set
Several fast interfaces set are connected with low temperature cylinder to be detected.
The utility model not only can be improved by the way that cold-trap is arranged in vacuum pump and low temperature cylinder to be detected and vacuumize effect
Rate, and gas cylinder temperature is reduced, the time for taking out one group of gas cylinder is fallen to 15 minutes by pervious two hours, replaces vacuum oil
Time changed by two days one and be extended for 25 days one changing, greatly improve production efficiency, reduce testing cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
1 vacuum pump, 2 cold-traps, 3 vacuum distribution pipes, 4 suction inlets, 5 corrugated stainless steel tubings, 6 fast interfaces in figure.
Specific embodiment
As shown, a kind of low temperature cylinder vacuum leak detector, including vacuum pump 1, cold-trap 2 and vacuum distribution pipe 3, vacuum
Pump 1 is connected with vacuum distribution pipe 3, several suction inlets 4 is arranged in vacuum distribution pipe 3, cold-trap 2 is by corrugated stainless steel tubing 5 and inhales
Entrance 4 is connected, and several fast interfaces 6 of the outlet of cold-trap 2 setting are connected with low temperature cylinder to be detected.
The utility model not only can be improved by the way that cold-trap is arranged in vacuum pump and low temperature cylinder to be detected and vacuumize effect
Rate, and gas cylinder temperature is reduced, the time for taking out one group of gas cylinder is fallen to 15 minutes by pervious two hours, replaces vacuum oil
Time changed by two days one and be extended for 25 days one changing, greatly improve production efficiency, reduce testing cost.
