Description
Technical field
The present invention relates to a kind of gas valve, relate in particular 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, on circumference of the surface of revolution of cock, interval arranges several fuel gas holes, the air inlet area of fuel gas hole is different, along with the rotation of cock, and inlet hole UNICOM or the disconnection of fuel gas hole and valve body.Such cock-type gas valve, although can adjust the velocity magnitude of ventilation, the air inlet sectional area difference of adjacent two fuel gas holes, so, when adjusting air inlet, the air inlet meeting produces sudden change, thereby make flame to become and to diminish greatly or suddenly suddenly.
Summary of the invention
The invention provides the linear flow cock gas valve of the adjustment air inflow that a kind of energy is level and smooth.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:
A kind of linear flow cock gas valve, comprise valve body and cock that mutual rotation coordinates; Offer blast tube in described cock; Set out gas port and suction port in described valve body; Described air outlet and blast tube UNICOM, suction port is aimed at the surface of revolution of cock; Offer a fuel tank on described surface of revolution; Along with surface of revolution rotation, 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 is offered fuel gas hole; Described fuel gas hole links fuel tank and blast tube.
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 the V-type groove, and its degree of depth becomes large gradually at circumferencial direction;
Also offer a compensating tank on described surface of revolution; Along with surface of revolution rotation, compensating tank and fuel tank simultaneously optionally with suction port UNICOM or disconnection, and when fuel gas hole and suction port UNICOM, compensating tank and suction port disconnection; 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 an end of compensating tank; Described fuel gas hole and compensate opening positioned opposite on surface of revolution.
Beneficial effect of the present invention is: along with the cock rotation, 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, when being beneficial to intake velocity and reaching maximum, air inlet is the most stable; When fuel gas hole is ventilated, combustion gas together with passing into by compensating tank and compensate opening compensation, thus while making suction port and the unexpected UNICOM of fuel gas hole, the unexpected change that can not produce intake velocity is large.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of linear flow cock gas valve of the present invention;
The structural representation that Fig. 2 is cock 2;
The A-A sectional view that Fig. 3 is Fig. 2;
The B-B sectional view that Fig. 4 is Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of linear flow cock gas valve of the present invention is made to detailed description:
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 is offered cock chamber 11,11Yu air outlet, cock chamber 12 UNICOMs, valve body 1 is offered a suction port 13 from bottom to top, suction port 13 and cock chamber 11 UNICOMs.
Offer a fuel tank 22 on the surface of contact of suction port 13 and surface of revolution 26, fuel tank 22 is positioned on a circumference of surface of revolution 26.Fuel tank 22 is the V-type groove, and its degree of depth counterclockwise becomes large gradually along circumference, thereby makes its ventilation sectional area counterclockwise become gradually large along fuel tank 22.Fuel tank 22 the darkest afterbodys, offer a fuel gas hole 23, fuel gas hole 23 UNICOM's fuel tanks 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.The shared central angle of fuel tank 22 and fuel gas hole 23 is 150 °.
Also offer a compensating tank 24 on the surface of contact of suction port 13 and surface of revolution 26, compensating tank 24 is also along circumferencial direction, and parallels with fuel tank 22.The clockwise afterbody of compensating tank 24 is offered a compensate opening 25, compensate opening 25 UNICOM's compensating tanks 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 do not arrive in a circumferential direction fuel gas hole 23, thus while making suction port 13 aim at fuel gas hole 23, can not with compensating tank 24 UNICOMs.The maximum ventilation sectional area sum of compensate opening 25 and fuel tank 22 equals the ventilation sectional area of fuel gas hole 23.
Compensating tank 24 and the shared central angle of 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 rotation, compensating tank 24 and fuel tank 22 simultaneously optionally with suction port 13 UNICOMs or disconnection, and when fuel gas hole 23 during with suction port 13 UNICOM, compensating tank 24 and suction port 13 disconnections.
When using, the valve rod 3 by cock 2 afterbodys reverses cocks 2, and when compensating tank 24 and fuel tank 22, during not with suction port 13 UNICOM, gas valve is closed, when clockwise torsion cock 2, suction port 13 and fuel tank 22 and compensating tank 24 UNICOMs, thereby gas valve is opened, along with continuing the cock 2 that turns clockwise, intake velocity by fuel tank 22 becomes large gradually, thereby make the intake velocity adjustment be linear change, when suction port 13 is aimed at the biggest place of fuel tank 22, 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, thereby make when suction port 13 forwards suddenly aligning fuel gas hole 23 to, intake velocity can not change, the sudden change that intake velocity changes can not occur, make the smooth-going maximum stable state that excessively arrives of gas flame.
