Abstract

The utility model discloses a nitrogen gas replacement valve, gas passage and petrol passageway have been seted up to its main part, realize injecting into nitrogen gas through gas passage under the ordinary pressure, let nitrogen gas be full of the remaining space of oil drum, the oil drum wall need not bear love pressure, improves the security, and original oil drum interface need not reform transform, maintains original closing cap structure.

Description

Nitrogen gas replacement valve

Technical Field

The utility model belongs to the gas exchange part, in particular to nitrogen gas replacement valve.

Background

Gasoline is usually stored and transported by adopting a special oil drum, generally speaking, the capacity of the gasoline in the drum is approximately 90% of the actual capacity, on the premise that the air tightness of the whole oil drum is kept, oil-gas mixed gas is easily generated in the residual space in the oil drum, and certain dangerous accidents can be generated under the influence of bumping and other adverse factors in the transportation process. In order to avoid the existence of a residual space in the oil drum, the current market mature method is that the oil drum is vacuumized to avoid the oxidation reaction caused by the contact with air, but because the inside of the oil drum generates negative pressure after vacuumization, the wall body of the oil drum can deform, so that the oil drum bears the pressure, the requirements on the performance of the oil drum are high, the manufacturing cost is high, more importantly, the requirements on gas exchange parts under vacuum or high pressure are particularly high, and the requirements on gas charging equipment are also particularly high.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model aims to provide a nitrogen gas replacement valve which is beneficial to gas-liquid exchange under normal pressure.

In order to realize the purpose, the utility model discloses a technical scheme is: the nitrogen gas replacement valve comprises a main body, wherein a gas channel and a gasoline channel are formed in the main body.

Further, the main body comprises a head and an insertion end, the gas channel penetrates through the head, and the gasoline channel penetrates through the head and the insertion end.

Further, the end head is a cylinder, and the insertion end is a semicircular body.

Furthermore, a baffle plate is arranged at the joint of the end head and the insertion end, and the gas channel faces the baffle plate.

Implement the utility model discloses technical scheme because gas passage and petrol passageway have been seted up to nitrogen gas change-over valve, realizes injecting into nitrogen gas through gas passage under the ordinary pressure, lets nitrogen gas be full of the oil drum and leaves the space, and the oil drum wall need not bear love pressure, improves the security, and original oil drum interface need not reform transform, maintains original closing cap structure.

Drawings

Fig. 1 is a schematic structural view of a nitrogen substitution valve.

Fig. 2 is a cross-sectional view of fig. 1.

Detailed Description

As shown in fig. 1, the body 1 of the nitrogen changeover valve is composed of a tip 1.1 and an insertion end 1.2. The end 1.1 is a cylinder, and the insertion end 1.2 is a semi-circle body. The main body 1 is provided with a gasoline channel 2, and the gasoline channel 2 penetrates through the end head 1.1 and the insertion end 1.2. The end 1.2 is provided with a gas channel 3, inert gas such as nitrogen can be introduced into the gas channel, and the diameter of the gas channel 3 is equal to 1/3 or 1/2 of the diameter of the gasoline channel 2. Baffle plates 6 are arranged at the inner end face of the end head 1.1 at intervals, the baffle plates 6 are arranged at the joint of the end head 1.1 and the insertion end 1.2, the gas channel 3 faces the baffle plates, the baffle plates play a role in buffering gas flow so as to avoid gasoline splashing, and the interval between the baffle plates and the inner end face of the end head is 3-10 mm. The gasoline channel 2 is provided with a gap 4, and the gap 4 is close to the baffle. The inboard plane of inserting end 1.2 is seted up spout 5, and spout 5 lock buoy 7, and the buoy can move along the spout.

Claims
