The utility model discloses effectively solved because steel bottle upper portion gas increases the problem that causes a bottle internal pressure rising, the frequent take -off of pipeline safety valve.
Description
Technical field
This utility model belongs to liquefied natural gas facility technical field, particularly a kind of device being automatically releasable liquefied natural gas steel cylinder hyperpressure.
Background technology
Liquefied natural gas as a kind of clean energy resource, industrial and civilian on be widely used.And after liquid gasification increases in liquefied natural gas steel cylinder, steel pressure of the inside of a bottle rises, causing that on pipeline, the frequent take-off of relief valve is diffused, cause gas to waste, for this situation, this is just strongly required a kind of device being automatically releasable liquefied natural gas steel cylinder hyperpressure.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of device being automatically releasable liquefied natural gas steel cylinder hyperpressure.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of device being automatically releasable liquefied natural gas steel cylinder hyperpressure, including multiple LNG steel cylinders arranged in parallel, each LNG steel cylinder is mounted on two stainless metal hoses, a metal hose on each LNG steel cylinder is connected by Subzero valve a and BOG gas phase discharge, another root metal hose on each LNG steel cylinder is connected by Subzero valve b and LNG liquid phase discharge, wherein, on the left of LNG liquid phase discharge, head end is provided with liquid feeding gun platform, on the right side of LNG liquid phase discharge, tail end is provided with Subzero valve c, wherein, on the left of BOG gas phase discharge, head end is provided with return-air gun platform, on the right side of BOG gas phase discharge, tail end is provided with reducer unit.
And, described reducer unit farther includes the bypass valve being serially connected in BOG gas phase gas collection pipe, is parallel with at the head and the tail two ends of bypass valve by valve, air relief valve before then leading to and the pipeline then leading to rear valve concatenation.
And, LNG liquid phase discharge is further fitted with relief valve a and Pressure gauge a.
And, BOG gas phase discharge is further fitted with relief valve b and Pressure gauge b.
Advantage of the present utility model and having the benefit effect that
This utility model flow process is simple, easily operated, keep in repair convenient transportation and safe and reliable cleaning, efficiently solves because steel cylinder upper gas increases and causes pressure of the inside of a bottle to raise, the problem of the frequent take-off of in-line relief valve.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of device being automatically releasable liquefied natural gas steel cylinder hyperpressure, as shown in Figure 1, including multiple LNG steel cylinders 17 arranged in parallel, each LNG steel cylinder is mounted on the metal hose 16 that two rustless steels are put, a metal hose on each LNG steel cylinder is connected by Subzero valve a15 and BOG gas phase discharge 10, another root metal hose on each LNG steel cylinder is connected by Subzero valve b14 and LNG liquid phase discharge 11, wherein, on the left of LNG liquid phase discharge, head end is provided with liquid feeding gun platform 2, on the right side of LNG liquid phase discharge, tail end is provided with Subzero valve c12, wherein, on the left of BOG gas phase discharge, head end is provided with return-air gun platform 3, on the right side of BOG gas phase discharge, tail end is provided with reducer unit.
In of the present utility model being embodied as, described reducer unit farther includes the bypass valve 9 being serially connected in BOG gas phase gas collection pipe, is parallel with at the head and the tail two ends of bypass valve by valve 6, air relief valve 7 before then leading to and the pipeline then leading to rear valve 8 concatenation.
In of the present utility model being embodied as, LNG liquid phase discharge is further fitted with relief valve a1 and Pressure gauge a13.
In of the present utility model being embodied as, BOG gas phase discharge is further fitted with relief valve b4 and Pressure gauge b5.
Operation principle of the present utility model:
First pass through liquid feeding gun platform and return-air gun platform to steel cylinder liquid feeding.Gas-liquid discharge end valve is then opened by use procedure and is connected with downstream, and the inlet pressure of air relief valve is set certain value in advance, automatically turn on when steel pressure of the inside of a bottle exceedes the setting value of air relief valve, combustion gas is then automatically discharged into downstream pipe by valve after then leading to front valve, air relief valve and then leading to, if do not overflowed, in steel cylinder, gas is then transported to downstream by bypass valve.In steel cylinder, liquid then passes sequentially through flange-connection stainless steel metal flexible pipe, Subzero valve b, Subzero valve c flow to downstream gas unit.
In this embodiment, the model of critical piece: steel cylinder is 175L1.6MPa；Subzero valve a, b and c are blue sky DJ61F-40PDN15 and DN40；Air relief valve is DY22F-25PDN25；Liquid phase relief valve is DA21F-40PDN15；Gas phase relief valve is DA22F-40PDN15.
