Abstract

The utility model discloses a device for preventing low-temperature gas from discharging and fully filling an operation box. The device comprises four safe valves (2) and is characterized by further comprising a confluence pipe (3) arranged on the operation box (1), wherein one end of the confluence pipe (3) is a gas charge end, the other end of the confluence pipe (3) is a gas discharge end communicated with atmosphere, and a gas outlet of each safe valve (2) is communicated with the gas charge end of the confluence pipe (3) through pipes. The device for preventing low-temperature gas from discharging and fully filling the operation box, disclosed by the utility model, enables gas discharged through the safe valves not to be filled in the operation box so as to solve a problem of safety of an operator.

Description

Prevent that the cryogenic gas discharging is full of the device of operating box

Technical field

The utility model relates to a kind of cryogenic gas that prevents and discharges the device that is full of operating box, is used for effectively preventing that the cryogenic gas discharging is full of the whole operation case.

Background technique

At present, for cryogenic gas, when the container inner pressure rising, when reaching the safety valve discharge pressure; Safety valve is opened, exhausting air, and for low-temperature tanker, the direct opening of Generally Recognized as safe valve outlet port is in operating box; The cryogenic gas of discharging is vaporized rapidly, is full of the whole operation case, influences operator's sight line.

Summary of the invention

The purpose of the utility model provides a kind of cryogenic gas that prevents and discharges the device that is full of operating box, and it can make the gas of safety valve discharging not in operating box, solves operator's safety problem.

The technological scheme that realizes the utility model purpose is: a kind of cryogenic gas that prevents discharges the device that is full of operating box; Comprise four safety valves; Also comprise the pipe that converges that is installed on the operating box; An end that converges pipe is an inlet end, and the other end is for being communicated with the exhaust end of atmosphere, and the outlet side of safety valve is communicated with the inlet end that converges pipe through pipeline.

Elbow structure is adopted in the outlet side of further, converging pipe.

After having adopted technique scheme, when container inner pressure reached the release pressure of safety valve, safety valve was opened, and cryogenic gas is discharged by safety valve, and the gas of four safety valve dischargings is guided to operating box and discharged outward through converging pipe.Like this, the gas of safety valve discharging just can not solve operator's safety problem in operating box.

In addition, the top of converging pipe also has an elbow, can prevent effectively that rainwater from pouring in down a chimney into to converge pipe.

Description of drawings

Fig. 1 is the schematic representation of the utility model.

Embodiment

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,

As shown in Figure 1; A kind of cryogenic gas that prevents discharges the device that is full of operating box; Comprise four safety valves 2, comprise that also being installed in converging on the operating box 1 manages 3, an end that converges pipe 3 is an inlet end; The other end is for being communicated with the exhaust end of atmosphere, and the outlet side of safety valve 2 is communicated with the inlet end that converges pipe 3 through pipeline.

As shown in Figure 1, converge the outlet side of pipe 3 and adopt elbow structure.

The working principle of the utility model is following:

When container inner pressure reached the release pressure of safety valve 2, safety valve 2 was opened, and cryogenic gas is discharged by safety valve 2, and the gas of four safety valve 2 dischargings is guided to operating box 1 outer the discharging through converging pipe 3.Like this, the gas of safety valve 2 dischargings just can not solve operator's safety problem in operating box 1.In addition, converge pipe 3 top and also have an elbow, can prevent effectively that rainwater from pouring in down a chimney into to converge pipe 3.

Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims

1. one kind prevents that the cryogenic gas discharging is full of the device of operating box; Comprise four safety valves (2); It is characterized in that: also comprise being installed in and converge pipe (3) on the operating box (1); An end that converges pipe (3) is an inlet end, and the other end is for being communicated with the exhaust end of atmosphere, and the outlet side of safety valve (2) is communicated with the inlet end that converges pipe (3) through pipeline.

2. the cryogenic gas that prevents according to claim 1 discharges the device that is full of operating box, it is characterized in that: elbow structure is adopted in described outlet side of converging pipe (3).
