Abstract
The utility model relates to a gas-saving device of a cryogenic liquid storage tank, which comprises a liquid storage tank, wherein a filling port is arranged at the top of the liquid storage tank, and a liquid outlet is arranged at the bottom of the liquid storage tank; the filling port is sequentially connected with a supercharger outlet valve and a top liquid filling valve through stainless steel pipes, and the stainless steel pipe between the supercharger outlet valve and the top liquid filling valve is respectively connected with a first pipeline safety valve, a pressure relief regulating valve and a pressure boosting regulating valve; the other end of the pressure relief regulating valve is sequentially connected with a check valve and a loop-saving cut-off valve through stainless steel pipes, and the stainless steel pipe between the check valve and the loop-saving cut-off valve is connected with a second pipeline safety valve; and the liquid outlet is connected with a liquid outlet valve through a stainless steel pipe, and the stainless steel pipe for connecting the liquid outlet and the liquid outlet valve is also connected with the loop-saving cut-off valve. In the utility model, the situation that gas in the liquid storage tank can be used up by customers can be ensured so as to avoid the unnecessary waste.
Description
Technical field
The utility model relates to a kind of gas-saving device of cryogenic liquid tank, is used for the cryogenic liquid tank saving of jar interior gas in use and uses.
Background technique
In use gas pressure raises cryogenic liquid tank in the basin because the spontaneous evaporation of basin causes at present, the basin applying unit in use is by the basin liquid outlet, cryogenic liquide is drawn by using behind the external vaporizer gasifying liquid, because what use is that the liquid phase valve can't use the gas in the basin, after sump pressure arrives to a certain degree, can only discharges and cause waste.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and a kind of gas-saving device of cryogenic liquid tank is provided, and this device can allow the client use up the interior gas of cryogenic liquid tank.
The technological scheme that realizes above-mentioned purpose is: a kind of gas-saving device of cryogenic liquid tank, comprise that the top has the mouth of filling, the bottom has the liquid storage tank of liquid outlet, fill mouth and be connected with supercharger outlet valve and top liquid-filling valve in turn by Stainless Steel Tube, be connected with first Piping Safety Valves respectively on the Stainless Steel Tube between supercharger outlet valve and the top liquid-filling valve, decompression pressure regulator valve and supercharging pressure regulator valve, the other end of decompression pressure regulator valve is connected with safety check in turn and saves the loop stop valve by Stainless Steel Tube, be connected with second Piping Safety Valves on the Stainless Steel Tube between safety check and the saving loop stop valve, liquid outlet is connected with the liquid outlet valve by Stainless Steel Tube, and the connection liquid outlet also is connected with saving loop stop valve with the Stainless Steel Tube of liquid outlet valve.
After adopting technique scheme, in use, save the loop stop valve, the supercharger outlet valve, the liquid outlet valve is often opened, the top is closed towards the liquid valve, the decompression pressure regulator valve is adjusted to spendable maximum pressure in the basin, when the basin internal pressure is higher than decompression pressure regulator valve setting pressure, the decompression pressure regulator valve will be opened, pressurized gas dash the dress mouth and enter from the top, by the supercharger outlet valve, the decompression pressure regulator valve, safety check, save the loop stop valve, flow to client's using end from the liquid outlet valve, when gas pressure in the jar during less than setting pressure, the decompression pressure regulator valve is an off state, then recovers normal and uses, thereby can guarantee that the client uses up the gas in the liquid storage tank, avoids unnecessary waste.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of gas-saving device of cryogenic liquid tank, comprising that the top has fills mouthfuls 10, the bottom has the liquid storage tank 12 of liquid outlet 11, fill mouthfuls 10 and be connected with supercharger outlet valve 5 and top liquid-filling valve 6 in turn by Stainless Steel Tube, be connected with first Piping Safety Valves 7 on the Stainless Steel Tube between supercharger outlet valve 5 and the top liquid-filling valve 6 respectively, decompression pressure regulator valve 4 and supercharging pressure regulator valve 8, the other end of decompression pressure regulator valve 4 is connected with safety check 3 in turn and saves loop stop valve 1 by Stainless Steel Tube, be connected with second Piping Safety Valves 2 on the Stainless Steel Tube between safety check 3 and the saving loop stop valve 1, liquid outlet 11 is connected with liquid outlet valve 9 by Stainless Steel Tube, and connection liquid outlet 2 also is connected with saving loop stop valve 1 with the Stainless Steel Tube of liquid outlet valve 9.
Working principle of the present utility model is as follows:
In use, save loop stop valve 1, supercharger outlet valve 5, liquid outlet valve 9 is often opened, the top is closed towards liquid valve 6, decompression pressure regulator valve 4 is adjusted to spendable maximum pressure in the basin, when the basin internal pressure is higher than decompression pressure regulator valve 4 setting pressures, decompression pressure regulator valve 4 will be opened, pressurized gas dash dress mouth 10 and enter from the top, by supercharger outlet valve 5, decompression pressure regulator valve 4, safety check 3, save loop stop valve 1, flow to client's using end from liquid outlet valve 9, when gas pressure in the jar during less than setting pressure, decompression pressure regulator valve 4 be an off state, then recovers normal use.
