Abstract
The utility model discloses a gas valve for a household gas cook stove. The opening and the closing of gas and the adjustment of flow can be controlled by reciprocating linear motion of a driving rod. Compared with the a plug valve of the household gas cook stove driven by adopting the traditional rotating mode, a sealing surface of the gas valve is only a matching plane of a valve core and a valve body as well as the valve core and a flow plate, so that the sealing area is greatly reduced and is about a half of the general plug valve of the gas stove, and further the friction resistance of the valve core during motion is reduced and the energy for driving is reduced. The gas valve is especially suitable for being driven by power devices such as a micro motor and the like.
Description
Technical field
The utility model is a kind of gas cooker parts, specifically is a kind of gas valve of household gas range.
Background technique
As everyone knows, household gas range gas valve commonly used be by the mode of rotary spool control combustion gas unlatching, close and the adjusting of flow size, be called stopcock.Characteristics such as this structure has easy processing, and is simple to operate.But because the stopcock employing is spool circumferential surface and valve interior wall face seal, therefore sealing surface is bigger, frictional force is big during rotation, thereby required moment is bigger when causing rotary spool, the performance when manually rotating of this shortcoming is not obvious, when adopting the micromachine equal power device to drive spool, because required moment just must ABAP Adapter be come drive motor than big, the dryelement cell that uses kitchen range to carry can cause dryelement cell to change the frequency height when driving, the kitchen range user cost increases.
Summary of the invention
The purpose of this utility model is to provide a kind of spool straight line moving type household gas range gas valve, reduce the sealing area of spool and valve body, thereby the resistance of reducing friction reduces energy needed when driving spool, is specially adapted to the household gas range gas valve that the micromachine equal power device drives.
The technical solution of the utility model is: this novel gas valve is made up of valve body, spool, traffic controller, compacting spring, sealing gasket, valve gap, O-ring seals, driveshaft.Described spool is installed in the valve body recess, by base plane and the suction port sealing that is located on the valve body, described traffic controller is installed on the spool, described traffic controller is provided with the flow control aperture of different size, the compacting spring is installed on traffic controller, and described valve gap is provided with the air outlet, and valve gap is by sealing gasket and valve body recess sealing, described driveshaft one end is connected with spool, and the other end stretches out valve body outward for user's operation by O-ring seals.
After adopting above structure, compared with prior art, the utlity model has following advantage: because this gas valve sealing surface only is spool and valve body, the spool plane that cooperates with current plate, significantly reduced sealing area, be about 1/2nd of normal domestic use gas cooker stopcock, thereby reduced surface friction drag, reduced energy required when driving, be specially adapted to the micromachine equal power device and drive.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, in this specific embodiment, the utility model gas valve is made up of valve body (1), spool (2), traffic controller (3), compacting spring (11), sealing gasket (8), valve gap (12), O-ring seals (14), driveshaft (7).Described spool (2) is installed in valve body (1) groove, by base plane and suction port (5) sealing that is located on the valve body, described traffic controller (3) is installed on the spool (2), traffic controller (3) is provided with the flow control hole (10) of several different sizes, compacting spring (11) is installed on the described traffic controller (3), described valve gap (12) is provided with air outlet (9), valve gap (12) is by sealing gasket (8) and the sealing of valve body (1) groove, spool attachment hole (13) on described driveshaft (7) one ends connect boss (6) and are located at spool (2) by driveshaft is connected, and the other end stretches out outside valve body (1) groove by O-ring seals (14).When the operator promotes driveshaft (7) when moving around, be embedded in driveshaft in the spool attachment hole (13) connect boss (6) drive spool (2) back and forth straight line move, the distance that this moment, the operator moved by controlling and driving bar (7), make the flow control hole (10) on valve core channel hole (4) the misalignment traffic controller (3) on the spool (2), realize closing of combustion gas.When the operator promotes driveshaft (7), when making the valve core channel hole (4) that is positioned on the spool (2) aim at the flow control hole (10) that is located on the traffic controller (3), combustion gas enters valve core channel hole (4) influent stream amount control hole (10) again from inlet hole (5), flow out from air outlet hole (9) at last, realize the unlatching of combustion gas.The operator also can promote driveshaft (7) and move different distances, makes valve core channel hole (4) aim at the flow control hole (10) of different size size, realizes the adjusting of gas valve flow size.When combustion gas entered valve body recess, O-ring seals (14), sealing gasket (8) can prevent that combustion gas from revealing from matching gap.When the sealing plane between spool (2) and valve body (1) and the traffic controller (3) weares and teares because of prolonged exercise, compacting spring (11) can utilize its deformation power to press down to make sealing plane remain sealing state, and the deformation power of suppressing spring (11) simultaneously can prevent that also gaseous-pressure from making spool (2) be caused combustion gas to be revealed from sealing plane by jack-up.
