Embodiment
Below by above-mentioned accompanying drawing embodiment the present invention is specifically addressed again.
Shown in Fig. 1～2, the improvement of two kinds of interchangeable stopcocks of source of the gas, include a valve body 3, valve body is provided with the gas-entered passageway 11 that connects source of the gas and the outlet passageway 12 of the output combustion gas that communicates with it, both all communicate with the taper hole inner chamber, and the outlet side of outlet passageway 12 is provided with nozzle, and nozzle can be the embedded nozzle (not shown) that is interference fitted in the outlet passageway, this nozzle injection diameter is 2.6 millimeters of φ 1.2～φ, is applicable to transport gas; Or the combination of the embedded nozzle and the first jointing type nozzle 2, as not establishing embedded nozzle, it also can be the combination of the first jointing type nozzle 2 and the second jointing type nozzle 1, the injection diameter of the second jointing type nozzle is 1.15 millimeters of φ 0.9～φ, be applicable to transportation of liquefied gas, require nozzle joint sealing without leakage, can change.Valve body 3 internal taper hole taperings are monolateral 5 °.
Be provided with the frustum shaped spool 4 that tapering matches and seals suit in valve body 3 taper holes, reach spool and valve body junction plane sealing purpose by spring 5 pushing tows that are located at the spool rear end, the other end of spring is sleeved on valve rod 9 ends that are located in the valve gap 7, valve gap and valve body are fixed, be provided with high boss and low boss in the valve gap, spring need have pretightening force, guarantees that spool combines with the sealing of valve body taper hole.Described spool 4 is processed with large through-hole b3, the guarantor fire hole b1 of circulation source of the gas and protects fire hole b2 on same radial cross section; large through-hole b3 is located on 90 ° of positions; protect fire hole b1 and be located at ° position, α=170; protect fire hole b2 and be located at ° position, β=250; open with valve body gas-entered passageway 11 respectively and communicate or close; and the b1 aperture is greater than the b2 aperture, and the b1 aperture is used for transport gas, and the b2 aperture is used for transportation of liquefied gas.The ignition mechanism (not shown) is realized igniting by valve rod 9 pushing tows, stopcock is installed in the combustion gas tool by 8 stop bits of the shaft block ring on the valve rod, handle rotating band movable valve plug 4 one-way synchronization of valve rod 9 and rotate, realize that the structure of the one-way synchronization rotation of valve rod and spool is made up of locating stud on the valve rod 6 and the groove (not shown) coupling on the spool 4.The large through-hole b3 that it is realization spool 4 that the manipulation valve rod rotates counterclockwise and drive the counterclockwise rotation synchronously of spool do and guarantor's fire hole b1, b2 accurately mate the processes that communicate with valve body gas-entered passageway 11 respectively; simultaneously between valve rod 9 and valve gap 7, be provided with corresponding bounding means; this bounding means comprises the locating stud 6 that is installed on the valve rod, be connected the adjustable locating pin 10 on the valve gap and be located at the high boss and the low boss (not shown) of valve gap inner chamber; the high 5.2mm of high boss, the low high 1.8mm of boss.High boss and low boss center of distribution angle are 250 °-90 °=160 ° valve gap inner chamber.Be provided with " O " RunddichtringO 13 between adjustable locating pin 10 and the valve gap 7, prevent to come off and waterproof action after adjustable locating pin 10 wearing and tearing.
Introduce the working procedure of this stopcock below again:
1, when valve rod attonity, spool were in 0 ° of state, gas-entered passageway was sealed by spool.
2, rotate counterclockwise 90 ° during when valve rod drives spool, be subjected to valve gap 7 low boss spacing to large through-hole b3 position, this moment spool large through-hole b3 with the perforation of valve body gas-entered passageway, export big flow source of the gas and realize big fire burns.
3, continue to rotate counterclockwise valve rod 9; locating stud 6 that is installed on it and spool 4 rotate synchronously; when valve core rotation during to ° position, angle [alpha]=170; locating stud is in that adjustable locating pin 10 under the state of screwing stops and is spacing; guarantor's fire hole b1 on the spool 4 just in time aligns with valve body gas-entered passageway 11 and communicates at this moment; through protecting fire hole b1 then from the nozzle ejection of outlet passageway 12, the throughput size of coming out from outlet passageway decides by protecting fire hole b1 and nozzle bore source of the gas from gas-entered passageway.
4; desire to want to exchange another kind of source of the gas; when needing spool guarantor fire hole b2 to communicate; it is spacing at first adjustable locating pin 10 to be withdrawed from releasing; valve rod 9 is rotated further; spool 4 corresponding rotations; when turning to ° position, β=250; locating stud 6 on it is collided spacing with the high boss in the valve gap 7; protecting fire hole b2 communicates with valve body gas-entered passageway 11 couplings; this moment, source of the gas was just sprayed by nozzle through outlet passageway 12 through spool guarantor fire hole b2 from the valve body gas-entered passageway again; finish the conveying of another kind of source of the gas, decided by protect fire hole b2 and nozzle bore by the throughput size that outlet passageway comes out this moment.
When handling valve rod, to note 2 points: 1. to make locating stud 6 cross low boss, during manipulation with valve rod toward interior pressure, just can be rotated further after making it cross low boss; 2. handle the perforation of guarantor fire hole b2 and gas-entered passageway and need withdraw from adjustable locating pin 10 earlier, and then rotary valve rod.
