Summary of the invention
For above deficiency, the purpose of this utility model there are provided a kind of three gas mixing valves, this valve adopts three groups of valves to be incorporated in the method for one, in the centre of valve body, mixed gaseous core is installed combustion gas, air, oxygen are mixed in valve body, be transported to burner place by air outlet adapter and lighted after-combustion, workpiece is processed.
The technical solution of the utility model is achieved in the following ways: a kind of three gas mixing valves, comprise a valve body, described valve body is provided with three air input joints arranged side by side and three air inlet adjustment mechanisms, it is characterized in that: described body cavity is provided with mixed air-casing and mixed gaseous core, the gas with various entered in valve body enters No. three air input joints and carries to air outlet adapter respectively by body cavity, mixed gaseous core, mixed air-casing, and carried on the pipeline as the connection of pagoda head by elbow bend after air outlet adapter mixing, carry out the blending transportation of three kinds of gases.
Described Mei Zu air inlet adjustment mechanism is all made up of mixed air-casing, air input joint, spring, sealing head, joint, sealing gasket, adjustable lever, adjustment cap and nut, air input joint is connected by ventilation cover with joint, adjustable lever is connected with joint screw thread with after adjustment cap compact siro spinning technology, and sealed by sealing gasket, cover has the sealing head of spring to be located at ventilation cover with in the cavity set by joint.
Described mixed air-casing and mixed gaseous core can move up and down according to the air inflow often organized in body cavity, rotate adjustment cap, adjustable lever advances along the hand of spiral of joint or screws out sealing head, the breeder tube that sealing head can block ventilation cover carries out sealing or opening, spring promotes the aperture that sealing head opens ventilation cover and carries out air inlet, after gas enters mixed air-casing in valve body and the mixing of mixed gaseous core, and is exported by air outlet adapter, spring-compressed, sealing head resets.
The utility model, three kinds of gases, simultaneously by screw thread air input joint, rotate adjustment cap, and adjustment cap drives adjustable lever to rotate, and adjustable lever loosens sealing head along the hand of spiral of joint, and spring promotes sealing head, and the aperture opening ventilation cover slowly carries out air inlet.The aperture that the gas entered from air input joint is overlapped along ventilation enters valve body.By valve body built with mixed air-casing and mixed gaseous core to the mixing of gas, to air outlet adapter conveying, gas by elbow bend conveying as pagoda head connect pipeline on, carry out the blending transportation of three kinds of gases.
