Abstract
Disclosed is a sub-cylinder for liquefied petroleum gas, which is mainly used in liquefied petroleum gas supplying system; the utility model is composed of a cylinder body, a sealing head, a liquid phase inlet flange connecting tube, a liquid valve flange connecting tube, a liquid distributing flange connecting tube and a contamination draining flange connecting tube. The sub-cylinder is connected at the outlet of agas pump; in the process of inflation for the steel cylinder for the user, the liquefied petroleum gas enters the inner of the sub-cylinder firstly, and then is filled into the steel cylinder; thus the vibration caused by the pipeline pressure in the liquefied petroleum gas system being too big can be avoided, so as to avoid the fire or the explosion accident.
Description
The utility model relates to a kind of liquefied petroleum gas (LPG) sub-cylinder.This sub-cylinder mainly uses in the LPG supply system, is taken over by cylindrical shell, end socket, the adapter of import liquid phase flange, the adapter of fluid valve flange, the adapter of separatory flange and blowdown flange and forms.
Before the utility model is made, do not adopt sub-cylinder in the LPG supply system, liquefied petroleum gas (LPG) is directly to be squeezed in the steel cylinder of user's use by air pump.By the fire-fighting requirement, be no less than 30 meters apart from the storage tank district between between the liquefied petroleum gas (LPG) compression, like this, when inflation, because pipeline is long and do not have sub-cylinder just to cause air feed to make pipeline leave a large amount of residual air greater than inflation easily, under pressure, the gas in the pipeline will produce judder, and pipe-line system is damaged and breaking out of fire or explosive accident.
The purpose of this utility model is to avoid providing of above-mentioned deficiency of the prior art to locate and a kind of liquefied petroleum gas (LPG) sub-cylinder product.
The purpose of this utility model can reach by following measure: this sub-cylinder is taken over by cylindrical shell (1), end socket (2) (3), import liquid phase flange that (4), gauge manifold (5), fluid valve flange are taken over (6), manually the flange that refluxes takes over that (7) separatory flange is taken over (8) and blowdown flange adapter (9) is formed.End socket (2) and envelope (3) are fixed on the two ends of cylindrical shell (1), take over (4), (5), (6), (7) evenly distribution is fixed on the circumferential surface of cylindrical shell (1), and on same plane, take over (4) in a side of taking over (5), take over (6), (7) at the opposite side of taking over (5), the blowdown flange is taken over (9) and is fixed on the circumferential surface of cylindrical shell (1), and with take over (4) on same plane but direction is opposite, the separatory flange is taken over (8) and is fixed on the circumferential surface of cylindrical shell (1), and its position is in cylindrical shell (1) the center line below of taking between (4) and the adapter (9).
The purpose of this utility model can also reach by following measure:
End socket (2) and end socket (3) are oval.
The end that import liquid phase flange is taken over (4) inserts in the cylindrical shell (1), and the end is 40mm apart from the cylindrical shell bottom.
It is 4 that the separatory flange is taken over (8), and is evenly distributed on the surface of cylindrical shell (1).
The drawing of accompanying drawing is described as follows:
Fig. 1 is a general assembly schematic representation of the present utility model, (1) cylindrical shell wherein, (2) (3) end socket, (4) import liquid phase flange is taken over, (5) gauge manifold, and (6) fluid valve flange is taken over, (7) flange that manually refluxes is taken over, and (8) separatory flange is taken over, and (9) blowdown flange is taken over.
The utility model is described in further detail below in conjunction with accompanying drawing:
This sub-cylinder is used to connect the air pump outlet in the LPG supply system, the liquefied petroleum gas (LPG) of being got by air pump enters in the cylindrical shell (1) through import liquid phase flange adapter (4), takes over (8) output through 4 separatory flanges again.When the pressure in the cylindrical shell (1) during greater than the pressure of pump, the fluid valve flange is taken over (6) and is opened automatically, before the liquefied petroleum gas (LPG) in the cylindrical shell flows back to storage tank or pump.Break down if the fluid valve flange is taken over (6), just strike out manual backflow flange with the hand and take over (7), take over (7) and can play the effect of adapter (6).The blowdown flange is taken over (9) and is used for blowdown and maintenance.Cylindrical shell of the present utility model adopts seamless steel pipe to manufacture.
The utility model has following advantage compared to existing technology:
1, can avoid owing to the excessive vibration that takes place of pipeline pressure in the Liquefied Petroleum Gas System.
2, make simply, cost is low.
3, be convenient to inflation.
