Detailed Description
The embodiments of the present invention will be described in detail with reference to the drawings, and the described embodiments are illustrative and explanatory of the present invention, and do not constitute the only limitations of the present invention.
As shown in fig. 1-3, the utility model discloses a valve body 8 and case 2 with gas passageway 1, the top of valve body be provided with gas passageway 1 the case installation blind hole that is linked together, the case step form big end down, the bottom of case has radial recess 21, the bottom of case with case installation blind hole cooperation installation, the exit of gas passageway connect the nozzle head, be provided with the fumarole 6 that the circumference distributes on the nozzle head.
Preferably, the valve core rotates the actuating element by 0-90 degrees, when the back surface of the radial groove is abutted and closed with the gas channel, the gas channel is closed, and the gas is supplied by adjusting the size of the gap between the radial groove and the gas channel.
Preferably, a bushing mounting hole is formed in an outlet, facing the gas channel, of the valve body, a bushing 3 is arranged in the bushing mounting hole, the bushing is provided with an ion detector extending into the gas channel, and the bushing extends into the outlet of the gas channel and is connected with a boss cylinder 7 arranged at the bottom of the nozzle head in a matched mode.
Preferably, the burner gas nozzle head further comprises a pressure measuring nozzle, a plug mounting hole 5 corresponding to the gas channel is formed in the side portion of the valve body, a sealing plug is arranged in the plug mounting hole, a pressure measuring nozzle mounting hole corresponding to the plug mounting hole is formed in the top portion of the valve body, and the pressure measuring nozzle 4 is mounted in the pressure measuring nozzle mounting hole, so that back pressure test is performed on the gas.
And a position limiting positioning piece hole 9 is arranged between the nozzle head and the frustum provided with the gas injection hole.
In addition, the upper and lower cylinders of the valve core are sealed by double high-temperature-resistant sealing bearings, so that the friction coefficient during axial rotation can be better reduced, the friction area between the valve core and the valve body is better reduced, and the service life is prolonged greatly.
