Abstract
The invention discloses a kind of pressurization leakage detection device of tank body vacuum jacket, it comprises forcing pipe, and one end of forcing pipe is intake interface, and is provided with gas admittance valve at this intake interface place, the other end of forcing pipe is provided with vacuum orifice adapter, and the middle part of forcing pipe is connected with tensimeter.Structure of the present invention is simple, can find out the undetected leak source of helium mass spectrum leak detection quickly and easily.
Description
Technical field
The present invention relates to a kind of pressurization leakage detection device of tank body vacuum jacket.
Background technology
At present, cryogenic liquid tank can carry out helium mass spectrum leak detection after tank body completes, check tank body leak source, under special circumstances, sometimes have undetected, cause the vacuum when vacuumizing cannot meet the requirements of consequence for a long time, and then need to re-start leak detection to tank body, carrying out second time when hunting leak, in order to get rid of the problem of helium mass spectrometer leak detector itself, and controlling cost that (helium needed for helium leak test is more expensive, and the time of hunting leak is longer), so need to adopt one both economical, leak hunting method efficiently, finds out the leak source of tank body.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of pressurization leakage detection device of tank body vacuum jacket, and its structure is simple, can find out the undetected leak source of helium mass spectrum leak detection quickly and easily.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of pressurization leakage detection device of tank body vacuum jacket, it comprises forcing pipe, one end of forcing pipe is intake interface, and at this intake interface place, gas admittance valve is installed, the other end of forcing pipe is provided with vacuum orifice adapter, and the middle part of forcing pipe is connected with tensimeter.
Further, described vacuumizing in adapter is provided with stationary installation, and this stationary installation comprises and is somely fixed on the bolt and nut component vacuumizing fixing fin in adapter and be arranged on fixing fin.
After have employed technique scheme, vacuum orifice adapter is enclosed within tank body to be vacuumized on interface, Nitrogen source gases is connected on intake interface, open gas admittance valve, nitrogen is filled with in interlayer, after arriving certain pressure, close gas admittance valve, tensimeter is observed in pressurize, as pressure gauge reading has decline, then illustrate that tank body has leak source, one by one the position that likely there is leak source is investigated by the watering can that suds are housed, be checked through leak source and continue aforesaid operations after reparation, until no longer change at packing stage pressure gauge reading, illustrate that now all leak sources have all been found out and repaired, the present invention finds out tank body leak source fast and easy, and structure of the present invention is also fairly simple, avoid and use helium mass spectrum to carry out secondary leak detection, reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pressurization leakage detection device of tank body vacuum jacket of the present invention.
Embodiment
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation,
As shown in Figure 1, a kind of pressurization leakage detection device of tank body vacuum jacket, it comprises forcing pipe 1, one end of forcing pipe 1 is intake interface 1-1, and at this intake interface 1-1 place, gas admittance valve 2 being installed, the other end of forcing pipe 1 is provided with vacuum orifice adapter 6, and the middle part of forcing pipe 1 is connected with tensimeter 3.Adopt structure above can find out tank body leak source quickly and easily, relatively simple for structure, avoid and use helium mass spectrum to carry out secondary leak detection, reduce cost.
As shown in Figure 1, vacuumize in adapter 6 and be provided with stationary installation, this stationary installation comprises four and is fixed on the fixing fin 5 vacuumized in adapter 6 and the bolt and nut component 4 be arranged on fixing fin 5.Stationary installation can make vacuum orifice take over to be enclosed within tank body securely and to vacuumize on interface, one end of the bolt in bolt and nut component 4 point is welded on the end socket of tank body, fastening nut, vacuum orifice just can be made to take over and be enclosed within securely on the vacuum orifice of tank body.
Principle of work of the present invention is as follows:
Vacuum orifice adapter 6 is enclosed within tank body to be vacuumized on interface, Nitrogen source gases is connected on intake interface 1-1, open gas admittance valve 2, nitrogen is filled with in interlayer, after arriving certain pressure, close gas admittance valve, tensimeter is observed in pressurize, as pressure gauge reading has decline, then illustrate that tank body has leak source, investigates the position that likely there is leak source one by one by the watering can that suds are housed, be checked through leak source and continue aforesaid operations after reparation, until no longer change at packing stage pressure gauge reading, illustrate that now all leak sources have all been found out and repaired.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
