Description
Technical field
The utility model relates to a kind of valve member, particularly relates to a kind of valve member of liquefied natural gas bottle.
Background technique
As shown in Figure 1, in the prior art, the shutoff valve that vehicle liquefied natural gas gas cylinder uses is all manually-operable.This valve comprises handle 31, stopper flap 32, valve rod 33, valve seat 34, liquid entering hole 35, liquid outlet 36.Above-mentioned shutoff valve working principle is as follows:
When valve first time open or valve be in closed condition need open time: manual anticlockwise valve handle 31, valve rod 33 drives airtight of the sealing surface of stopper flap 32 and valve seat 34 to be separated, and liquid flows to liquid outlet 36 from liquid entering hole 35, valve opening;
When valve be in opening state need close time: manual right rotation valve handle 31, stopper flap 32 relies on the pressure of valve rod 33, stopper flap 32 sealing surface and valve seat IV sealing surface are fitted tightly, and what stop liquid flows to liquid outlet 36 from liquid entering hole 35, valve closing.
In aforesaid operations process, when opening valve, needing to hold handle 31 anticlockwise 3.5 and enclosing, then right rotation 0.5 circle prevents valve from freezing to death; If when storage pressure is not enough, only the valve opening of individual layer gas cylinder need be held handle 31 anticlockwise 10.5 and encloses, and right rotation 1.5 is enclosed; Owing in gas cylinder being gas, the liquid mixture of subzero more than 100 degrees Celsius, if valve opening speed is comparatively slow or the difference of valve mass, opening difficulty just increases greatly.Therefore there is large, the unhandy defect of operation easier.

The gas of pass valve suction tude, the flowing of valve opening suction tude is non-combustible gas.
According to the valve member of the utility model embodiment, without the need to loaded down with trivial details manually-operable program; Valve also opens and closes along with the ON/OFF of the power supply of electric controller thereupon, thus facilitates the open and close of valve.
Accompanying drawing explanation
Fig. 1 shows the valve of prior art;
Fig. 2 shows the pneumatic control valve of the utility model embodiment;
Fig. 3 shows the valve member of the utility model embodiment.
Embodiment
Understand for the ease of persons skilled in the art and realize the utility model, now describing embodiment of the present utility model by reference to the accompanying drawings.
As Figure 2-3, present embodiments provide a kind of valve member, it is applied to liquefied natural gas bottle, comprising: pneumatic control valve 1; Electric controller 4, it comprises pass valve air gate A1 and valve opening air outlet B1; Close valve suction tude 2, its one end communicates with the pass valve suction port A of pneumatic control valve 1, and the other end communicates with the pass valve suction port A1 of electric controller 4; Valve opening suction tude 3, its one end communicates with the valve opening suction port B of pneumatic control valve 1, and the other end communicates with the valve opening air outlet B1 of electric controller 4; Air pump (not shown), vehicle reservation tank can be used as air pump; Suction tude 5, its one end is connected with solenoid valve 4, and the other end is connected with air pump, to keep the pressure of described suction tude 5.According to the utility model, preferably, described electric controller can be solenoid valve.
As shown in Figure 2, Fig. 2 is a kind of liquified natural gas pneumatic control valve, and effect is equivalent to the function of the hand stop valve of existing use.Described pneumatic control valve 1 comprises: Pneumatic cover 11, Pneumatic valve housing 12, valve body 13, spring 14, Sealing 15, SEALING FITTING 16, leakage preventing plug 17, close valve suction port A and valve opening suction port B and multiplely tightly plug with molten metal nut.Wherein, spring 14 is embedded in Pneumatic cover 11, and to suppress Sealing 15, SEALING FITTING 16 is arranged on the end of Sealing 15.
Introduce the working principle of pneumatic control valve 1 below.Connect source of the gas, described source of the gas is non-combustible gas, non-combustible gas is entered Sealing 15 jack-up in valve body by valve opening suction port B, Sealing 15 is with leakage preventing plug 17, the SEALING FITTING 16 be dynamically connected that valve is in open mode, and namely rock gas flows to outlet end from the inducer C of pneumatic control valve.When the non-combustible gas of pneumatic valve stops circulating, pneumatic control valve seal 15, leakage preventing plug 17, SEALING FITTING 16 are withstood to force valve 1 to be in closed condition with the gas of the pass valve suction port A of valve 1 by spring 14 jointly.Gas in bottle will no longer flow out in pneumatic control valve.The sealing gasket that SEALING FITTING 16 uses is cryogenic material, can not cause damage because liquid stabilising is low.
As shown in Figure 3, the valve member of Fig. 3 the utility model embodiment.The working principle of the valve member of the utility model embodiment is once described below again.
When non-combustible gas enters after in electric controller 4, open the 24V power switch that electric controller 4 uses, valve opening air outlet B1 opened by electric controller 4, and valve air gate A1 is closed the border in pass.Like this, non-combustible gas is delivered in pneumatic control valve 1 by valve opening air outlet B1, valve opening suction tude 3 and valve opening suction port B, thus by Sealing 15 jack-up of pneumatic control valve 1, inflammable gas passes through;
When closing the 24V power supply that electric controller 4 uses, electric controller 4 cuts out valve opening air outlet B1, open and close valve air gate A1, like this, non-combustible gas is delivered in pneumatic control valve 1 by closing valve air gate A1, closing valve suction tude 2 and closing valve suction port A, thus makes jointly to oppress the Sealing 15 of pneumatic control valve 1 with throttle down with the spring 14 of pneumatic control valve 1.Therefore, valve member of the present utility model effectively can ensure unlatching or the closedown of pneumatic control valve 1.
Due to the elastic force of spring 14, when valve member is because of power-off or when dying, pneumatic control valve 1 is in closed condition.
Pneumatic control valve is directly installed on gas cylinder, by non-combustible gas by valve open, so can pass through pneumatic control valve by property gas.Model utility
According to embodiment of the present utility model, connect source of the gas, after power-on, valve can be opened automatically; The gas pipeline of powered-down or cutting-off valve, valve can be closed automatically.
Although depict the utility model by embodiment, but those of ordinary skill in the art know, when not departing from spirit of the present utility model and essence, the utility model just can be made to have many distortion and change, and scope of the present utility model is limited to the appended claims.
