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 material selection

     Regulate the use of gas cooker valves for corrosion resistance, pressure and temperature have a rating almost demanding, therefore, the current multi-use cast iron gas cooker valve, which can effectively improve the corrosion resistance regulating gas cooker valve with compressive strength; in the regulation the internal components of the Gas Cooker valves material, more use of stainless steel, if the system requirements for the amount of leakage is small, you can choose a soft seal, if the system requirements for the amount of leakage is high, you need to use Hastelloy.

     In the selection of gas cooker safety valve, the need to consider the liquid concentration, temperature and pressure, combined with mechanical shock selection.

The structure and selection of gas burner valve

     Depending on its stroke, pneumatic control gas burner valve can be divided into two different types, namely, the angle straight trip itinerary, according to the structure points, pneumatic control gas burner valve can be divided into the butterfly, angle gas brass safety valve, sleeve gas burner valves, ball gas burner valves, diaphragm gas burner valves, Globe gas burner valves and other types.

     Which, through single-seat control gas burner valve is the process of using the minimum amount of gas burner valve leakage, flow performance ideal, simple structure, can be used to leak demanding area, but its passage is relatively complex, which to some extent limit the scope of its use.

     Through engine gas burner valve is through single-seat control gas burner valve opposite a gas Burner Valves, there is no strict requirements for leakage, suitable for use in large-area working pressure at present, through engine regulation is our most extensive range of applications a control gas burner valve.

     Sleeve gas burner valve can be divided into two types, namely double sealed sleeve gas burner valve with single seal sleeve gas burner valve, the gas burner valve sleeve has a good stability, low noise, easy accessibility, but its price is relatively high, and higher Range Top Burner Valve maintenance requirements Therefore, using the range are also some limitations.

     Diaphragm flow path is simple, its production and use is also high corrosion resistance PT-FE and PFA, it is suitable for application in alkali or acid environment, but relatively poor regulation.

Gas Burner Valves angle bevel laser cutting process

To complete the total Gas Burner Valves angle of 31.5 ° bevel cut, to be produced in Figure 2 cut-precision tooling, tooling hydraulic positioning pitch pitch Gongyi scale manipulation within ± 0.01mm, shroud segment selection process after welding, dealt with a full circle around the ramp beyond Æ 3000mm. The Gas Cooker valves problem can not be processed.
Adjust the coupling of laser processing parameters, the laser power P = 1260W, cutting speed v = 1.4m / min, generally oxygen (99.8% purity) as his assistant, gas, gas pressure is 0.08MPa, you can accomplish the viewpoint bevel laser cutting kerf width of about 0.18mm.
Laser head nozzle spacing change from the Gas Burner Safety Valve and the amount of gas burner valve have a significant impact on the quality of cut, the nozzle is too far away from the workpiece make kerf widening, roughness progress, nozzle spacing too easily with the workpiece attack bump. Spacing from the workpiece handling between 0.5 ~ 0.8mm, preferably cut after the cavity surface quality. The amount of coke (ie, the orientation of the laser focus within the workpiece) about 1mm, ensuring smooth cut, does not render the entrance slit Burner Valves, made an outstanding appearance and processing quality.

Often switching can lead to self-closing valve

      On the gas stove does not conduct regular inspections, appears damaged (such as gas safety burner valve, gaskets, hoses damaged), resulting in a gas leak, or operations are not standardized (eg lying cylinders, high temperature baking, do not close the valve after use, etc.), but also easy fire caused by an explosion.

     At home on the gas pipeline, we can see a similar "circle Peas' device - self-closing valve is under abnormal conditions to prevent gas output, self-closing valve.

     Self-closing valve in the pipe network will automatically shut down or stop gas pressure is too large, in a normal state, self-closing valve reset button at the Green Line trolley scale state, when the red line reset button on the pop-up lever, proof pressure within the gas pipeline too large, self-closing valve itself off; when the reset button lever fully recovered, then stop gas pipeline network or the occurrence of gas hose off, self-closing valve also shuts itself down. After many users are accustomed to the use of natural gas each self-closing valve manually shut down, it is not right, often open and close easily self-closing valve malfunction, causing leaks. Every time we finished dinner, turn off the stove valve, then close the gas cooker safety valve to the stove.
