Dish valve.
Background technology
Current conventional dish valve, valve body is interior to have columnar valve pocket, and axial length is short, dish plate built in valve pocket, dish plate
By the valve rod drive through valve pocket, rotation valve rod changes the deflection angle of dish plate, you can controls the flow of gas.Dish plate and valve pocket
When cross section angle is 0 °, valve pocket is blocked by dish plate, and butterfly valve is closed；Dish plate and valve pocket cross section angle（Valve is opened
Degree）When not being 0 °, the equal shape between the valve pocket inwall of the axial plane both sides where valve pocket axis and valve rod axis and dish plate periphery
Into flow channels, valve pocket is opened, and butterfly valve is in open mode.
Due to being respectively formed flow channels, and section of flow channels between the valve pocket inwall of axial plane both sides and dish plate periphery
Area increases rapidly with the increase of the aperture of valve, so being compared by the fluid flow of flow channels and the aperture linearity of valve
Difference.Especially valve aperture in the range of 0 ° -30 °, fluid flow increases rapidly with the aperture linearity of valve, with opening for valve
It is worse to spend the linearity.This causes being precisely controlled for flow is difficult to accomplish, especially being precisely controlled in the less scope of flow
It is more difficult to.
If common butterfly valve is used in gas burner and the flow of fuel gas is controlled, the flow of fuel gas
Low precision is controlled in Smaller load, can cause to waste fuel gas.

The beneficial effect of this technology：This high-precision regulation disc valve is provided with half on the valve pocket inwall of axial plane side and blocked
Ring, when the aperture of such valve is less than a, half curved surface for blocking ring contacts with dish plate periphery, that is to say, that sets half valve for blocking ring
It is closed state between cavity wall and dish plate periphery, fluid can not be by, and is not provided with the opposite side valve pocket inwall of half closure ring
It is identical with common butterfly valve structure between dish plate periphery, fluid can pass through.In other words, when the aperture of valve is less than a, only
There are the flow channels passed through for fluid in the side of axial plane, so, the line of the aperture of valve in the range of less than a with flow
Property degree improved a lot compared to common butterfly valve tool, drive dish plate to rotate by rotation valve rod, flow can be precisely controlled.
