Double plate gas cooker valve

① wedge gate Gas Cooker valves sealing performance than good, such as when oblique angle and seat sealing surface with not very accurate, and still has a good seal;

② after gate sealing surface wear, the metal sphere at the bottom of the top center of the pad can be used to change a thicker, generally do not have welding and grinding sealing surface, this is a single gate, flexible gate difficult to achieve.

③ parts than other forms of multi-gate;

④ In addition to apply steam, oil and other media, but also applies to the site of frequent switching and wear on the sealing surface of the medium, not for easy coking medium.

(4) parallel gate gas cooker valve

① sealing gas cooker valve than other forms of difference;

② suitable for medium temperature and low pressure;

③ In addition to the gate with fixed panels on two easy to fall off the gate, where the lead wire is fixed with two shutter gate easy to fall off, using unreliable.

Processing and maintenance ④ gate and seat sealing surface of the gas cooker valve is simpler than other forms.

Gas cooker valve operational use

     Gas cooker valve before operating the gas cooker valve must be familiar with the technical parameters of equipment, technical knowledge to understand the principles, structures and other equipment. Before moving the gas cooker valve, make sure the pipes and Gas Cooker valves have been cleaned. Ensure flexible gas cooker valve easy to use, no run, run, drip, drain phenomenon. In the obtained production scheduling permission, perform the gas cooker valve opening and closing operation.

     Typically ball gas cooker valve hand wheel clockwise to open the gas cooker valve counter-clockwise to close the gas cooker valve hand wheel (ie, cis-open reverse off). Operation of the gas cooker valve actuator input signal according to the size of the drive stem rotation is completed: the forward 1/4 turn (90 °), the gas cooker valve is turned off. Counter-rotating 1/4 turn (90 °), the gas cooker valve opens. When the actuator direction arrow parallel with the pipeline, the gas cooker valve is open. Vertical arrow indicating the pipeline, the gas cookers for sale is closed. Not use brute force when operating gas cooker valve switch, hard to open hard off, in order to avoid damage to the gas cooker valve actuator. Ball can be used as the transmission medium truncated pipeline, can not be used as a throttle gas cooking valves.
