Abstract

The utility model relates to an opening and closing valve for timing gas control, which belongs to a gas opening and closing apparatus and comprises a valve cover, a valve body, a base, a rubber ring for cover sealing, a rubber ring of a pressure valve, a corrugation rubber ring, a timing control disc, a timer, a spring and a turning button. Opening and closing of a valve is controlled by a mechanical timer to complete time control function. A cone pressure valve is provided with an upper and a lower sealing rings to guarantee isolation of a control device and the valve to make the utility model safe and leakproof. The utility model has the characteristics of safety, stabilization, reliability and simple manufacture.

Description

Regularly combustion gas opens and closes valve

The utility model belongs to combustion gas and opens and closes utensil.

The function that common gas valve is just opened and closed, manually opened, after achieving the goal, manual-lock again, inconvenient timing, and, if forget and close, also can cause serious loss.

The utility model is that a kind of combustion gas that can overcome above-mentioned shortcoming opens and closes utensil.It is made up of valve gap 1, suction port 2, spring 3, cap seal cushion rubber 4, pressure valve cushion rubber 5, valve body 6, pedestal 7, screw 8, air outlet 9, ripple cushion rubber 10, nut 11, timing controlled dish 12, timer 13, knob 14 parts, it is characterized in that having a cylinder valve body, epimere compresses by spring and pedestal, and the timing controlled dish of a hypomere and a timer is connected.

Figure of description 1 is the utility model sectional drawing, and Fig. 2 is valve body figure, and Fig. 3 is timing controlled dish figure, and Fig. 4 is ripple cushion rubber figure, originally is described further for the utility model in conjunction with the accompanying drawings.

Referring to Fig. 1, the general suction port 2 of peace on the valve gap 1, lid inwall center is provided with short column, and axle makes spring 3 be placed in wherein location together on valve body 6; Lid is convenient to install along being provided with six screws; Cap seal cushion rubber 4 is positioned on the pedestal 7 in the shallow ring recess, prevents gas leakage.The pedestal 7 post hearts have dug " Y " shape hole, and general air outlet 9 communicates with it.

Referring to Fig. 2,6 epimeres of valve body are the inverted cone platform, establish on the conical surface and press valve cushion rubber 5, constitute cone valve, guarantee to close reliable.The axle hypomere is a cylinder, and with the inverted cone platform one spacing being arranged is gas circuit, and the post lower shaft has screw thread, and most advanced and sophisticated is taper.

Referring to Fig. 1, valve body 6 cylinders cooperate closely with bottom, " Y " shape hole, but can freely move up and down, and ripple cushion rubber 10 usefulness nuts 11 are clamped on the cylinder, make air tightly, and the ripple cushion rubber is referring to Fig. 4.Timer 13 adopts one hour or two hours mechanical timer timing mechanisms, can be regularly, also can often open, but the timer loam cake changes " recessed " shown in empty frame shape into, make it and

pedestal

7 and 10 compactings of ripple cushion rubber, there is the trapezoidal shallow slot of circle pedestal 7 lower ends, make ripple cushion rubber 10 that activity space and location be arranged, and prevent down gas leakage.

Referring to Fig. 1, control panel 12 links to each other with timer, and profile is referring to Fig. 3, and there is conelet hole its outer.When timer is closed, spring 3 presses valve 6 bottoms to fall in its hole, and borrow elastic force that cone valve cuts out, when the 14 rotation timings of timing knob, control panel 12 also pushes valve body 6 bottoms and goes out the hole thereupon rotating, make it to rise and open cone valve, gas circuit is open-minded, turns to the hole to valve body 6 bottoms when timing controlled dish 12 returns zero with timing, under spring 3 pressure, cone valve falls to cutting out, and closes thereby reach automatically; When timer 13 often left, then control panel 12 was extruded and is not rotated the gas circuit normal open after valve body 6 goes out the hole; Change the open degree that the timing controlled dish 12 awl hole degree of depth then can change valve body 6.

The utility model O-ring seal is made with rubber, and other is made by plastics, metal; Multiple seal has guaranteed the isolation of valve and control gear, and safety, stable, reliable is suitable for natural gas or liquid gas timing controlled especially and opens and closes.
