Description
Technical field
The present invention relates to a kind of gas valve, particularly relate to a kind of linear flow cock gas valve.
Background technique
Conventional cock-type gas valve, mainly comprise valve body and cock, cock coordinates with valve body rotary seal, the inside of cock and air outlet hole UNICOM, the surface of revolution one of cock circumferentially interval several fuel gas hole is set, the air inlet area of fuel gas hole is different, along with the rotation of cock, and the inlet hole UNICOM of fuel gas hole and valve body or disconnection.Such cock-type gas valve, although can adjust the velocity magnitude of ventilation, the air inlet sectional area of adjacent two fuel gas holes is different, so when adjustment air inlet, air inlet can produce sudden change, thus flame can be diminished greatly or suddenly suddenly in change.
Summary of the invention
The invention provides the linear flow cock gas valve of the level and smooth adjustment air inflow of a kind of energy.In order to realize foregoing invention object, present invention employs following technological means:
A kind of linear flow cock gas valve, comprises valve body and the cock of mutual rotatable engagement; Blast tube is offered in described cock; Gas port and suction port is set out in described valve body; Described air outlet and blast tube UNICOM, the surface of revolution of cock aimed at by suction port; Described surface of revolution is offered a fuel tank; Along with surface of revolution rotate, fuel tank optionally with suction port UNICOM or disconnection; The ventilation sectional area of described fuel tank becomes large gradually; On described surface of revolution, the ventilation sectional area biggest place of fuel tank offers fuel gas hole; Described fuel gas hole makes fuel tank and blast tube be connected.
Described fuel tank is along a circumferencial direction of surface of revolution;
The ventilation sectional area of described fuel gas hole is greater than fuel tank;
Described fuel tank is V-type groove, and its degree of depth becomes large gradually at circumferencial direction;
Described surface of revolution is also offered a compensating tank; Along with surface of revolution rotates, the while of compensating tank and fuel tank optionally with suction port UNICOM or disconnection, and when fuel gas hole and suction port UNICOM, compensating tank and suction port disconnect; Described compensating tank is by compensate opening and blast tube UNICOM; The maximum ventilation sectional area sum of described compensate opening and fuel tank equals the ventilation sectional area of fuel gas hole;
Described compensating tank is parallel to fuel tank, and the two is positioned at the same side of surface of revolution;
Described compensate opening is positioned at one end of compensating tank; Described fuel gas hole and compensate opening are positioned opposite on surface of revolution.
Beneficial effect of the present invention is: along with cock rotates, the air inlet sectional area of fuel tank gradually changes, thus adjustment intake velocity that can be level and smooth; The setting of fuel gas hole, be beneficial to intake velocity when reaching maximum, air inlet is the most stable; While fuel gas hole ventilation, by compensating tank and compensate opening compensate pass into together with combustion gas, thus when making suction port and the unexpected UNICOM of fuel gas hole, the unexpected change that can not produce intake velocity is large.

Embodiment
Below in conjunction with accompanying drawing, detailed description is made to the preferred implementation of a kind of linear flow cock gas valve of the present invention:
As shown in Figure 1, this linear flow cock gas valve mainly comprises valve body 1 and cock 2, and the inner left end of valve body 1 sets out gas port 12, right-hand member offers cock chamber 11, cock chamber 11 and air outlet 12 UNICOM, valve body 1 offers a suction port 13 from bottom to top, suction port 13 and cock chamber 11 UNICOM.
Cock chamber 11 is a Frusto-conical cavity, and install cock 2 in it, the surface of revolution 26 of cock 2 is also conical butt, and shape and cock chamber 11 are sealed and matched.Surface of revolution 26 aimed at by suction port 13.A columniform blast tube 21 is offered in cock 2 inside, and it is inner that position is positioned at surface of revolution 26, and one end is closed, and the other end opening is towards air outlet 12.
Suction port 13 with the surface of contact of surface of revolution 26 offers a fuel tank 22, fuel tank 22 is positioned at one of surface of revolution 26 circumferentially.Fuel tank 22 is V-type groove, and its degree of depth circumferentially counterclockwise becomes large gradually, thus makes its ventilation sectional area counterclockwise become large gradually along fuel tank 22.The darkest afterbody of fuel tank 22, offers a fuel gas hole 23, fuel gas hole 23 UNICOM fuel tank 22 and blast tube 21.The air inlet sectional area of fuel gas hole 23 is greater than the air inlet sectional area of fuel tank 22.Fuel tank 22 and the central angle shared by fuel gas hole 23 are 150 °.
Suction port 13 and the surface of contact of surface of revolution 26 also offer a compensating tank 24, and compensating tank 24 also circumferentially, and parallels with fuel tank 22.The clockwise afterbody of compensating tank 24 offers a compensate opening 25, compensate opening 25 UNICOM compensating tank 24 and blast tube 21, and the air inlet sectional area of compensate opening 25 is less than the air inlet sectional area of compensating tank 24.The length of compensating tank 24 is suitable with fuel tank 22, and corresponding with the position of fuel tank 22 at the axial direction compensating tank 24 of surface of revolution 26.And the counterclockwise afterbody of compensating tank 24 is corresponding with the counterclockwise afterbody of fuel tank 22, and does not arrive at fuel gas hole 23 in a circumferential direction, thus when making suction port 13 aim at fuel gas hole 23, can not with compensating tank 24 UNICOM.Compensate opening 25 equals the ventilation sectional area of fuel gas hole 23 with the maximum ventilation sectional area sum of fuel tank 22.
Compensating tank 24 and the central angle shared by compensate opening 25 are about 155 °.Fuel gas hole 23 and compensate opening 25 are positioned at the diameter two ends of a circumference of surface of revolution 26.Along with surface of revolution 26 rotates, compensating tank 24 and fuel tank 22 simultaneously optionally with suction port 13 UNICOM or disconnection, and when fuel gas hole 23 and suction port 13 UNICOM, compensating tank 24 and suction port 13 disconnect.
When using, reverse cock 2 by the valve rod 3 of cock 2 afterbody, when compensating tank 24 and fuel tank 22 be not with suction port 13 UNICOM, gas valve is closed, when reversing cock 2 clockwise, suction port 13 and fuel tank 22 and compensating tank 24 UNICOM, thus gas valve is opened, along with continuing the cock 2 that turns clockwise, become large gradually by the intake velocity of fuel tank 22, thus intake velocity adjustment is linearly changed, when the biggest place of fuel tank 22 aimed at by suction port 13, the air inlet sectional area sum of fuel tank 22 and compensate opening 25 equals the air inlet sectional area of fuel gas hole 23, thus make when suction port 13 forwards suddenly aligning fuel gas hole 23 to, intake velocity can not change, namely the sudden change of intake velocity change can not be there is, make gas flame smooth-going excessively to maximum stable state.
