Problems solved by technology

Although such a cock-type gas valve can adjust the speed of ventilation, the cross-sectional area of ​​the air intake of two adjacent gas holes is different, so when the air intake is adjusted, the intake air will change abruptly, so that the flame will suddenly become larger or larger. suddenly become smaller

Embodiment Construction

[0016] A preferred embodiment of a linear flow cock gas valve of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0017] like figure 1 As shown, the linear flow cock gas valve mainly includes a valve body 1 and a cock 2. The left end of the valve body 1 is provided with an air outlet 12, and the right end is provided with a cock chamber 11. The cock chamber 11 communicates with the air outlet 12. The valve body 1 is opened from bottom to top. An air inlet 13, the air inlet 13 communicates with the cock chamber 11.

[0018] The cock cavity 11 is a truncated conical cavity, in which the cock 2 is installed, and the rotating surface 26 of the cock 2 is also truncated conical, and its shape is in sealing fit with the cock cavity 11 . The air inlet 13 is aligned with the rotating surface 26 . A cylindrical gas channel 21 is opened inside the cock 2 , and the position is located inside the rotating surface 26 , one end is clo...

Abstract

The invention relates to a gas valve, in particular to a linear-flow-rate cock gas valve. The linear-flow-rate cock gas valve comprises a valve body and a cock, wherein a gas passage is formed in the cock, a gas outlet and a gas inlet are formed in the valve body, the gas outlet is communicated with the gas passage, the gas inlet is aligned with a rotation face of the cock, a gas trough is formed in the rotation face, the gas trough is selectively communicated with or cut off from the gas inlet along with the rotation of the rotation face, the gas through section area of the gas trough becomes large gradually, a gas hole is formed in the rotation face at a position when the gas through section area of the gas trough is largest, and the gas hole enables the gas trough to be communicated with the gas passage. The gas intake section area is gradually changed along with the rotation of the cock, and accordingly, the gas intake speed can be smoothly adjusted.

Description

technical field [0001] The invention relates to a gas valve, in particular to a linear flow cock gas valve. Background technique [0002] The conventional cock type gas valve mainly includes a valve body and a cock. The cock and the valve body are rotated and sealed in cooperation. The areas are different, and with the rotation of the cock, the gas hole is connected or disconnected with the air inlet hole of the valve body. Although such a cock-type gas valve can adjust the speed of ventilation, the cross-sectional area of ​​the air intake of two adjacent gas holes is different, so when the air intake is adjusted, the intake air will change abruptly, so that the flame will suddenly become larger or larger. suddenly become smaller. Contents of the invention [0003] The invention provides a linear flow cock gas valve capable of smoothly adjusting the intake air volume. In order to realize the above-mentioned purpose of the invention, the present invention adopts the foll...
