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 utility model, comprise valve body 1, be arranged on the valve port 2 of valve body 1 side, and the piston 5 that is arranged on valve body 1 inside, it is characterized in that, crown cap 3 is set above valve body 1, top cap 3 inside, be provided with needle-valve 4 on the top cavity of piston 5, the side of piston 5 is provided with stria along cross-sectional direction, side at valve body 1, be provided with and get gas plug 11 over against the stria position of piston 5, get on gas plug 11 and be provided with the plug screw adapted with the stria specification, the below, side of valve body 1 is provided with rupture disk unit 10, pore is set or opening is set on the base 6 of piston 5, be provided with steel wire in opening 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 also is provided with monitor unit plug 7, pressure gauge plug 9, the top, side of valve body 1 also is provided with solenoid valve plug 8, described monitor unit plug 7, solenoid valve plug 8, pressure gauge plug 9 all adopts the 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 utility model 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 utility model unit 10 comprises explosion plug 16 and explosion plug screw 17, cap 3 belows, top of the present utility model are horizontally arranged with an O RunddichtringO 18, the upper end of piston 5 vertically is 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 vertically are provided with the 4th O RunddichtringO 21, the manufactured materials of the utility model bottle valve is carbon steel, the valve body of bottle valve and valve port adopt cast inblock.
First the utility model bottle valve is connected on gas cylinder by bottom thread, by external air source, pressurize and the opening regulating action of piston base 6, 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, played the effect of closing bottle valve again.
In use; usually 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 be provided with steel wire in opening to reduce the aperture of circulating; the tonifying Qi speed of piston 5 belows is less than the disappointing speed in top; piston 5 upwards is moved under the effect of pressure difference, finally opens valve port 2, and in bottle, gas and medium are through valve port 2 ejections.
When needs working pressure table is checked pressure of the inside of a bottle, pressure gauge is connected with miniature thimble through the needle-valve module with valve body, and when 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 the needs replacing, 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, after the replacing pressure gauge, is connected use with miniature thimble with the needle-valve module again.
When needs working pressure monitor unit, thimble module directly can be connected with the connecting end of monitor unit, also can with the monitor unit joint, closely be connected by metal tube and high pressure hose.When 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 the needs replacing, 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, after the replacing monitor unit, is connected use with thimble module again.Easily realize installation and removal by this kind of mode, the utility model is particularly useful for the explosion-proof type pressure monitor that boundary dimension is larger, and maintenance is convenient and swift.
When special occasions need to be used solenoid valve startup or explosion-proof type solenoid valve to start, the utility model is applicable 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 the solenoid valve inner chamber.When closing, bear high pressure when solenoid valve, when providing actuating signal, solenoid valve is opened, and valve pocket pressure reduces with exhaust rapidly, and bottle valve is opened.When 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 the diaphragm explosion with the bottle of releasing in during material, the utility model can be selected this locality to release or be guided to safety zone to be released 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 realizes that this locality releases.When explosion plug screw 17 direct connecting pipeline joint, explosion plug 16 is replaced by the pipeline inipple and is connected with the 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 the safety zone discharge by pipeline.
Because top of the present utility model has adopted integral design, and reinforce by the two seals circle, so it is very little that the gas leakage probability occurs in top of the present utility model, be generally piston 5 lower ends than under small probability, because O RunddichtringO or needle-valve damage, causing gas leakage, need to change element and when in bottle, carrying out tonifying Qi, can first the plug screw of getting on gas plug 11 be screwed in to the stria on piston 5 sides, lock piston 5 no longer is 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, through top cap 3 threaded couplings or solenoid valve plug 8, with the utility model modular type differential pressure bottle valve, be connected, carry out slow tonifying Qi, reach the top and the bottom pressure balance when the gas cylinder internal pressure through the opening of base 6, after pressure gauge is confirmed to reach predetermined value, the plug screw of getting on gas plug 11 is screwed out to stria, tonifying Qi finishes.
The utility model bottle valve can be realized several functions, can coordinate and realize that anti-explosion is electromagnetic starts, pressure of the inside of a bottle monitors, 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 have greatly been improved, and when the utility model bottle valve discharges the interior article of bottle, ejected matter is even, use installation reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
