Abstract

The utility model discloses a pressurizing leakage detection device for a vacuum clamping sleeve of a tank. The pressurizing and leakage detection device comprises a pressurizing pipe; an air inlet port is formed at one end of the pressurizing pipe; an air inlet valve is arranged in the position of the air inlet port; a vacuuming port connecting pipe is arranged at the other end of the pressurizing pipe; and pressure gauges are connected to the middle part of the pressurizing pipe. The pressurizing leakage detection device for the vacuum clamping sleeve of the tank is simple in structure, and can be used for conveniently and quickly finding out a leakage point which is failed to be detected in helium mass spectrometer leak detection.

Description

The pressurization leakage detection apparatus of tank body vacuum jacket

Technical field

The utility model relates to a kind of pressurization leakage detection apparatus 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 the tank body leak source, under special circumstances, sometimes have omission, cause that vacuum can't meet the requirements of consequence for a long time when vacuumizing, and then need hunt leak again to tank body, when carrying out hunting leak the second time, in order to get rid of the problem of helium mass spectrometer leak detector itself, and control cost that (the required helium of helium leak test is more expensive, and the leak detection time is longer), so need to adopt a kind of both economically, leak hunting method is efficiently found out the leak source of tank body.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of pressurization leakage detection apparatus of tank body vacuum jacket is provided, its leak source simple in structure, that can find out the helium mass spectrum leak detection omission quickly and easily.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of pressurization leakage detection apparatus 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 and takes over, and the middle part of forcing pipe is connected with tensimeter.

Further, described vacuumizing is equipped with stationary installation in the adapter, and this stationary installation comprises and somely is fixed on the fixedly fin that vacuumizes in the adapter and is arranged on bolt and nut component on the fixing fin.

After having adopted technique scheme, the vacuum orifice adapter is enclosed within tank body to vacuumize on the interface, the nitrogen source of the gas is connected on the intake interface, open gas admittance valve, in interlayer, charge into nitrogen, after arriving certain pressure, close gas admittance valve, tensimeter is observed in pressurize, as pressure gauge reading decline is arranged, and illustrates that then tank body has leak source, take the watering can that suds are housed one by one the position that might have leak source to be investigated, be checked through leak source and repair back continuation aforesaid operations, until no longer changing at the packing stage pressure gauge reading, illustrate that all leak sources were all found out and repaired this moment, it is fast convenient that the utility model is found out the tank body leak source, and the utility model structure is also fairly simple, has avoided use helium mass spectrum to carry out the secondary leak detection, has reduced cost.

Description of drawings

Fig. 1 is the structural representation of the pressurization leakage detection apparatus of tank body vacuum jacket of the present utility model.

Embodiment

Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below,

As shown in Figure 1, a kind of pressurization leakage detection apparatus 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 is installed, and the other end of forcing pipe 1 is provided with vacuum orifice and takes over 6, and the middle part of forcing pipe 1 is connected with tensimeter 3.Structure above adopting can be found out the tank body leak source quickly and easily, and is relatively simple for structure, avoided use helium mass spectrum to carry out the secondary leak detection, reduced cost.

As shown in Figure 1, vacuumize to take on 6 stationary installation is installed, this stationary installation comprises that four are fixed on and vacuumize the fixedly fin of taking on 65 and be arranged on bolt and nut component 4 on the fixing fin 5.Stationary installation can make the vacuum orifice adapter be enclosed within tank body securely and vacuumize on the interface, and an end points of the bolt in the bolt and nut component 4 is welded on the end socket of tank body, and fastening nut just can make vacuum orifice take over and be enclosed within securely on the vacuum orifice of tank body.

Principle of work of the present utility model is as follows:

Vacuum orifice adapter 6 is enclosed within tank body to vacuumize on the interface, the nitrogen source of the gas is connected on the intake interface 1-1, open gas admittance valve 2, in interlayer, charge into nitrogen, after arriving certain pressure, close gas admittance valve, tensimeter is observed in pressurize, as pressure gauge reading decline is arranged, illustrate that then tank body has leak source, take the watering can that suds are housed one by one the position that might have leak source to be investigated, be checked through leak source and repair back continuation aforesaid operations, until no longer changing at the packing stage pressure gauge reading, illustrate that all leak sources were all found out and repaired this moment.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
