Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
By Fig. 3, Fig. 4, Fig. 5 A, Fig. 5 B as seen: the present invention includes: oxygen air inlet 270, combustion gas air inlet 280, preheated oxygen control valve that connects preheated oxygen 210 240, cutting oxygen control valve that connects cutting oxygen 220 250, a gas control valve 260 that connects combustion gas 230; Described oxygen air inlet 270, combustion gas air inlet 280, preheated oxygen control valve 240, cutting oxygen control valve 250, gas control valve 260 are joined by high-speed switch handle and the distributor valve body 290 that is connected handle 300 controls with one;
Described distributor valve body 290 comprises: first cavity 291 that connects oxygen air inlet 270, one second cavity 292, one connect combustion gas air inlet 280 the 3rd cavity 293; In first cavity 291, comprise: cutting oxygen valve rod 2911; In second cavity 292, comprise: preheated oxygen valve rod 2921; In the 3rd cavity 293, comprise: combustion gas valve rod 2931; Described high-speed switch handle comprises: cutting oxygen handle 2915, preheated oxygen handle 2925 and combustion gas handle 2935; Connect handle 300 and connect preheated oxygen handle 2925 and combustion gas handle 2935; Connect handle 300 at the other breach 3001 that placement cutting oxygen handle 2915 is arranged of the side of preheated oxygen handle 2925; Cutting oxygen handle 2915, preheated oxygen handle 2925, combustion gas handle 2935 and connection handle 300 comprise three position locations: be respectively closed position 301, preheating position 302 and cutting position 303; The position of one end of described position location corresponding cutting oxygen handle 2915, preheated oxygen handle 2925 and combustion gas handle 2935 is connected with corresponding cutting oxygen valve bar 2911 preheat oxygen valve rods 2921 combustion gas valve rods 2931; The other end of cutting oxygen valve rod 2911, preheated oxygen valve rod 2921, combustion gas valve rod 2931 communicates or connects airtight and touch with cutting oxygen control valve 250, preheated oxygen control valve 240, gas control valve 260 by first coil tension spring 2912, second coil tension spring 2922, the 3rd coil tension spring 2932 corresponding with it respectively;
Cutting oxygen handle 2915, preheated oxygen handle 2925, combustion gas handle 2935 and connect handle 300 when closed position 301, described cutting oxygen valve rod 2911, preheated oxygen valve rod 2921, valve one end that combustion gas valve rod 2931 is corresponding with it connect airtight and touch; Cutting oxygen handle 2915, preheated oxygen handle 2925, combustion gas handle 2935 and connection handle 300 are when preheating position 302, valve one end that described cutting oxygen valve rod 2911 is corresponding with it connects airtight and touches, and valve one end corresponding with it of preheated oxygen valve rod 2921, combustion gas valve rod 2931 communicates; Cutting oxygen handle 2915, preheated oxygen handle 2925, combustion gas handle 2935 and connect handle 300 when cutting position 303, described cutting oxygen valve rod 2911, preheated oxygen valve rod 2921, valve one end that combustion gas valve rod 2931 is corresponding with it communicate.
By Fig. 6 A, Fig. 6 B, Fig. 6 C as seen: the present invention is according to job requirement, when the high-speed switch handle in the closed position 301 the time, because the elastic force of holddown spring makes the valve rod that has airtight and watertight padding connect airtight with valve body and touches, the elastic force owing to three coil tension springs allows whole gas circuit be in closed condition; Turn connects handle 300 to preheating position 302, the high-speed switch handle moves a certain distance valve rod, combustion gas valve rod and the preheated oxygen valve rod effect of being stressed this moment retreats the coil tension spring compression, airtight and watertight padding on the valve rod separates with valve body, make gas circuit unobstructed, and this moment, cutting oxygen valve rod position did not change, so this moment, the cutting oxygen road still was a closed condition; When preheating is finished, turn cutting oxygen handle is to cutting position 303, cutting oxygen handle moves a certain distance the cutting oxygen valve bar, the effect of being stressed of cutting oxygen valve rod retreats the coil tension spring compression, airtight and watertight padding on the valve rod separates with valve body, and whole gas circuit becomes promptly to become open state, promptly can be used to cutting steel plate, cutting will connect handle after finishing and be threaded to and close 301 positions, and whole gas circuit is closed.
During preheating, combustion gas and preheat oxygen are the while open mode, and cutting oxygen is closed condition at this moment, so require when preheating, combustion gas is accomplished synchronously with the switch of preheat oxygen; And when cutting and closing, the switch of three road gases also will be accomplished synchronously.Therefore, preheat oxygen handle and combustion gas handle are coupled together, realize that preheat oxygen handle and combustion gas handle rotate synchronously by connecting handle.Leave a breach on the connection handle, when opening oxygen gas, cutting oxygen handle is not connected handle to be controlled, and realizes warm; During rotation cutting oxygen handle to 303 position, cutting oxygen handle just is positioned at the indentation, there that connects handle, and this moment, whole gas circuit was in open state, can realize cutting process; Finish when cutting, the handle that is rotationally connected utilizes spring force auxiliary, makes cutting oxygen handle and oxygen gas handle 301 positions of returning fast; Realization utilizes a handle to control the quick closedown of whole gas circuit.Adapted O type circle and airtight and watertight padding on valve rod simultaneously guarantees the sealing of whole gas circuit.
When the present invention will connect handle and forward preheating position 302 to, can open preheated oxygen and combustion gas simultaneously, this moment the preheating steel plate of the cutting torch point of gas cutting machine can being fought, in the time of will cutting the oxygen handle after preheating is finished and forward cutting position 303 to, cutting oxygen i.e. upright this is opened, and finishes cutting; To connect handle after cutting is finished and get back to the supply that original position is promptly cut off oxygen gas.Repeatedly cut the steel plate of same thickness, need not to adjust oxygen again, gas valve can be finished cutting.
