Abstract
The present invention proposes a kind of tank car air inlet pumping device, including tube socket, the tube socket flange being connect with tube socket, tube socket blind flange, blast pipe, liquid suction pipe and coupling flange, coupling flange lid；Blast pipe, liquid suction pipe are welded as entirety with coupling flange tube socket blind flange respectively, then are fixedly connected with tube socket flange, and liquid suction pipe penetrates through entire tube socket, and gas-phase space is connected to gas-phase space in liquid suction pipe in tank, and the upper end in blast pipe and liquid suction pipe is arranged in coupling flange.Tank car of the present invention air inlet pumping device, pumping device structure are designed to that air inlet drawing liquid Contiuum type of structure, disjunctor are entered the wind pumping device and be mounted on tube socket by flange, gas-phase space in tank are made to be connected to gas-phase space in liquid suction pipe.
Description
Technical field
The present invention relates to unload pumping device on tank car field more particularly to a kind of non-pressure tank car.
Background technology：
The current tank car in China, top of the tank are equipped with the liquid suction pipe 10 at blast pipe and straight-through tank base liquid trap, see
Fig. 1 is mainly used for drawing liquid car unloading operation, should close tightly blast pipe 11 and liquid suction pipe blind flange in vehicle normal operation, keep away
Exempt from medium in tank to leak.
It is loaded onto on existing and unloads drawing liquid assembly and deposit and have the disadvantage that：Structure function disadvantage：1) gas-phase space pressure and pumping in tank
Gas-phase space pressure imbalance in liquid pipe.Tank body is after being exposed to the sun, and gas-phase space pressure increases in tank, when liquid suction pipe blind flange is close
When envelope is not tight, medium is forced out by being inserted into the liquid suction pipe of liquid Space.2) liquid suction pipe top meteorological spatial pressure is avoided when entrucking
Power increases, it is necessary to open liquid suction pipe blind flange.Cost, quality disadvantage：1) former unloading pipe connection, blind flange are all made of casting method
Manufacture, casting technique is complicated, of high cost.2) there are mass defects for casting, are transported on dress corrosive liquids (acid, alkali) tank car in installation
When, casting flaw easily causes corrosion aggravation.
Invention content
In order to solve the technical problem in the presence of background technology, the present invention proposes a kind of tank car air inlet drawing liquid
Device, pumping device structure are designed to that air inlet drawing liquid Contiuum type of structure, disjunctor enter the wind pumping device and be mounted on tube socket by flange
On, so that gas-phase space in tank is connected to gas-phase space in liquid suction pipe.
Technical solution of the invention is：Tank car air inlet pumping device, it is characterised in that：Enter the wind pumping device
Tube socket flange, tube socket blind flange, blast pipe, liquid suction pipe and coupling flange, the coupling flange being connect including tube socket, with tube socket
Lid；The blast pipe, liquid suction pipe are welded as entirety with coupling flange tube socket blind flange respectively, then are fixedly connected with tube socket flange,
Liquid suction pipe penetrates through entire tube socket, and gas-phase space be connected to gas-phase space in liquid suction pipe in tank, coupling flange be arranged in blast pipe and
The upper end of liquid suction pipe.
Above-mentioned coupling flange covers setting communicating passage and covers, in coupling flange lid setting both ends respectively with blast pipe and pumping
The communicating passage of liquid pipe connection.
Above-mentioned coupling flange passes through loose joint bolt and hinge connection with coupling flange lid.
Above-mentioned communicating passage capping is fixedly connected by welding with coupling flange lid.
Sealing ring is arranged in the junction of blast pipe, liquid suction pipe respectively with coupling flange in above-mentioned coupling flange lid.
Above-mentioned tube socket flange upper connector seat blind flange, is arranged sealing ring between tube socket blind flange and tube socket flange.
The advantageous effect of the air inlet pumping device of the present invention：
Structural advantages：
1) it is connected to tank body meteorological spatial in liquid suction pipe, thoroughly liquid level difference phenomenon in elimination liquid suction pipe and in tank body.With
Family is lack of standardization using operating, and when liquid suction pipe coupling flange bonnet bolt does not fasten uniformly, also will not generate leakage in liquid suction pipe flange
Liquid phenomenon.
2) blast pipe, liquid suction pipe are welded on a tube socket blind flange, are mounted on flange, and the trepanning on tank body is reduced
Quantity.
Quality, cost advantages：
1) change original cast type accessory, avoid casting caused mass defect.
2) all accessories (are contacted) except proximate matter with conveying medium and are all made of the processing of the wrought forms such as steel plate, casting is saved and adds
Work cost.
Service advantages：
1) blast pipe liquid suction pipe Contiuum type of structure is saved in entrucking and opens liquid suction pipe coupling flange lid process.
2) pumping device is entered the wind, process simplicity is opened, also reduces the danger that operator opens liquid suction pipe (acid, lye) corrosion
Danger.
