Embodiment
Embodiment 1:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, modular type differential pressure bottle valve of the present invention, comprise valve body 1, be arranged on the valve port 2 of valve body 1 side, and be arranged on the piston 5 of valve body 1 inside, it is characterized in that, crown cap 3 is set above valve body 1, top cap 3 inside, on the top cavity of piston 5, be provided with needle-valve 4, the side of piston 5 is provided with stria along cross-sectional direction, in the side of valve body 1, just the stria position of piston 5 is provided with and gets gas plug 11, get and on gas plug 11, be provided with the plug screw adapting with stria specification, the below, side of valve body 1 is provided with rupture disk unit 10, on the base 6 of piston 5, pore is set or opening is set, in opening, be provided with steel wire to reduce the aperture of circulating, valve body 1 below and gas cylinder contact segment are provided with screw thread and seal ring, wherein, the below, side of valve body 1 is also provided with monitor unit plug 7, pressure gauge plug 9, the top, side of valve body 1 is also provided with solenoid valve plug 8, described monitor unit plug 7, solenoid valve plug 8, pressure gauge plug 9 all adopts needle-valve module to replace, described needle-valve module comprises needle-valve 12 and needle-valve module body 13.Needle-valve module of the present invention can be combined with thimble module, described thimble module comprises thimble 14 and thimble module body 15, with so that the gas in gas cylinder be passed in the cavity of thimble module, rupture disk of the present invention unit 10 comprises explosion plug 16 and explosion plug screw 17, cap 3 belows, top of the present invention are horizontally arranged with an O RunddichtringO 18, the upper end of piston 5 is vertically provided with the 2nd O RunddichtringO 19, the lower end of piston 5 is horizontally arranged with the 3rd O RunddichtringO 20, piston 5 bottoms are vertically provided with the 4th O RunddichtringO 21, the manufactured materials of bottle valve of the present invention is carbon steel, the valve body of bottle valve and valve port adopt cast inblock.
First bottle valve of the present invention is connected on gas cylinder by bottom thread, pressurize and the opening regulating action of piston base 6 by external air source, piston 5 is pressed down to bottom, the gentle pressure of the inside of a bottle balance of piston 5 upper cavity, through the 3rd O RunddichtringO 20, the 4th O RunddichtringO 21 twice isolating seals, play the effect of closing bottle valve again.
In use; conventionally can take the thimble of manual starter, air starter or motor starter to clash into; thimble moves down the valve rod that acts on needle-valve 4; needle-valve 4 is opened; piston 5 top cavitys are communicated with outside; produce slowly venting; owing on base 6, opening being set; and in opening, be provided with steel wire to reduce the aperture of circulating; the tonifying Qi speed of piston 5 belows is less than the disappointing speed in top; piston 5 is upwards moved under the effect of pressure difference, finally opens valve port 2, and in bottle, gas and medium spray through valve port 2.
In the time that needs working pressure table is checked pressure of the inside of a bottle, pressure gauge is connected through needle-valve module and miniature thimble with valve body, and in the time screwing pressure gauge, the built-in thimble of pressure gauge connecting end backs down needle-valve 12, in bottle, medium is communicated with pressure gauge, realizes long-term display bottle internal pressure value.When pressure gauge is damaged need to change time, pressure gauge is unscrewed, the miniature thimble in it no longer acts on needle-valve 12, and needle-valve module self-closed, can not cause gas leak, is connected use again after changing pressure gauge with miniature thimble and needle-valve module.
In the time of needs working pressure monitor unit, thimble module directly can be connected with the connecting end of monitor unit, also can closely be connected with monitor unit joint by metal tube and high pressure hose.In the time that thimble module is screwed with the needle-valve module that replaces monitor unit plug 7, thimble 14 backs down needle-valve 12, and in bottle, medium is communicated with monitor unit, realizes monitored for prolonged periods of time pressure of the inside of a bottle value.When monitor unit is damaged need to change time, first thimble module is unscrewed, in it, thimble 14 no longer acts on needle-valve 12, and needle-valve module self-closed, can not cause gas leak, is connected use after changing monitor unit with thimble module again.Easily realize installation and removal by this kind of mode, the present invention is particularly useful for the explosion-proof type pressure monitor that boundary dimension is larger, and maintenance is convenient and swift.
In the time that special occasions need to use solenoid valve startup or explosion-proof type solenoid valve to start, the present invention is suitable for too, the joint of solenoid valve is connected with thimble module, again thimble module is screwed in to the needle-valve module of having replaced solenoid valve plug 8, thimble 14 in thimble module acts on needle-valve 12, needle-valve is opened, and in bottle, medium is communicated with solenoid valve inner chamber.When solenoid valve is when cutting out, bear high pressure, in the time providing actuating signal, solenoid valve is opened, and valve pocket pressure reduces with exhaust rapidly, and bottle valve is opened.In the time that solenoid valve needs regular maintenance, unscrew thimble module needle-valve 12 and close, now can carry out maintenance work to solenoid valve.
When needs carry out diaphragm explosion with the bottle of releasing in when material, the present invention can select this locality to release or be guided to safety zone to release as required.When explosion plug 16 is spun on explosion plug screw 17 and does not hinder while releasing, explosion plug screw 17 planes are concordant with explosion plug 16 exterior edge faces, and in bottle, medium can the aperture on explosion plug screw 17 be realized this locality and released.In the time of explosion plug screw 17 direct connecting pipeline joint, explosion plug 16 is replaced by pipeline inipple and is connected with bleeder pipe terminal.This pipe joint is threaded to explosion plug screw 17 thread roots, blocks the aperture of releasing on it, the medium of releasing can be guided to safety zone discharge by pipeline.
Because top of the present invention has adopted integral design, and reinforce by two seals circle, so it is very little to there is gas leakage probability in top of the present invention, be generally piston 5 lower ends compared with causing gas leakage because O type circle or needle-valve damage under small probability, need to change element and when carrying out tonifying Qi in bottle, can first the plug screw of getting on gas plug 11 be screwed in to the stria on piston 5 sides, lock piston 5 is no longer moved, then the element of damage is changed, the plug screw of getting on gas plug 11 is screwed out to stria, then thimble module is connected with the breather line of on-the-spot tonifying Qi gas cylinder, be connected with modular type differential pressure bottle valve of the present invention through top cap 3 threaded couplings or solenoid valve plug 8, carry out slow tonifying Qi, when gas cylinder internal pressure reaches top and the bottom pressure balance through the opening of base 6, confirm to reach after predetermined value through pressure gauge, the plug screw of getting on gas plug 11 is screwed out to stria, tonifying Qi finishes.
Bottle valve of the present invention can be realized several functions, can coordinate and realize anti-explosion is electromagnetic startup, pressure of the inside of a bottle supervision, long-term display bottle internal pressure, and pressure gauge is changed at the scene of realizing, water conservancy diversion etc. after explosion, applicability and the maintenance update convenience of bottle valve are greatly improved, and ejected matter is even when bottle valve of the present invention discharges the interior article of bottle, use installation reliable.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
