Fig. 2 is the plan view of gas control valve shown in Figure 1;
Fig. 3 is the spool schematic representation of gas control valve shown in Figure 1.
[embodiment]
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Please refer to Fig. 1 and Fig. 2, the preferred embodiments of the utility model provides a kind of gas control valve, comprises the valve body 1 that is provided with blast tube 3 and moves the spool 2 that is arranged in the said blast tube 3.Blast tube 3 has a passage conical surface 8, spool 2 have a passage conical surface 8 with blast tube 3 and blast tube 3 match control gas flow spool conical surface 9.
The blast tube 3 of this gas control valve comprises air outlet 4 and suction port 5, and this gas control valve comprises outlet connection 6 and inlet union 7, and outlet connection 6 is fixed on the air outlet 4, and inlet union 7 is fixed on the suction port 5.Blast tube 3 is 6 formed passages from inlet union 7 to outlet connection like this.The passage conical surface 8 here can be arranged at the position that is connected with air outlet 4 on the outlet connection 6, promptly on the inwall of outlet connection 6.Certainly, the air outlet 4 of valve body also can have long passage, thereby makes passage conical surface 8 can be arranged on the inwall of valve body rather than on the inwall of outlet connection, passage conical surface 8 also can be arranged on the correct position at suction port 5 places.Passage conical surface 8 is arranged on the inwall of outlet connection 6, with respect to being arranged in the valve body 1, has advantage easy to process.
Please refer to Fig. 3; Preferable; In order to make between spool conical surface 9 and the blast tube 3 sectional area that allows the slit that combustion gas passes through along with moving of spool 2 is better linear relationship, the spool conical surface 9 of this gas control valve comprises first conical surface 14, second conical surface 15, the 3rd conical surface 12 and the 4th conical surface 13.Wherein, the cone angle of second conical surface is 15 degree, and the cone angle of the 3rd conical surface is 17 degree, and the cone angle of the 4th conical surface is 43 degree.Such design can make between gas flow and the spool displacement distance and present better linear relationship.First conical surface 14 is provided with the seal ring 10 with seal action.When this gas control valve stops gas from valve body, to flow out fully, first conical surface 14 of spool 2 will closely contact with passage conical surface 8, and the seal ring 10 here will play seal action, stop gas to pass through.In addition, in order to guarantee tightness, also be provided with seal ring 10 between outlet connection 6 and the air outlet 4 and between inlet union 7 and the suction port 5 with seal action.
Spool 2 removable being arranged in the blast tube 3 of this gas control valve.This gas control valve also comprises the drive unit 11 that a control spool 2 moves in blast tube 3.This drive unit 11 links to each other with spool 2, moves in blast tube 3 thereby drive spool 2.This drive unit 11 can be stepper motor or other suitable device.Be provided with seal ring 10 between position that spool 2 is connected with drive unit 11 and the blast tube 3 with seal action.Sealing circle 10 can guarantee to remain tightness when spool 2 moves in blast tube 3, thereby makes the combustion gas can be from blast tube 3 internal leakages to valve body 2 outsides.
The blast tube of the gas control valve of the utility model has the passage conical surface, and spool has the spool conical surface.During this gas control valve work; Spool moves in blast tube; Make and produce the slit that allows combustion gas to pass through between spool conical surface and blast tube and the passage conical surface; The sectional area that allows the slit that combustion gas passes through between spool conical surface and the blast tube is along with moving of spool is linear change, thereby makes the displacement distance of gas flow and spool through blast tube linear.Like this, when using ECU when carrying out flow control through the combustion gas of gas control valve, can control according to gas flow and the linear relationship between the spool displacement distance, owing to being linear relationship, the control of ECU will be more convenient, simple.
The above embodiment has only expressed several kinds of mode of executions of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
