Abstract:
    The present invention is a control valve of high pressure dusty gas. To radically prevent the control valve from being frayed and prevent the dust particles from going to control valve, the interior of the valve box is subdivided in sections with at least two conical bores with different cone angles. Thus the state of air flow is improvedand uniform velocity distribution is obtained on the cross section of the air flow without forming eddy flow and separating parts, thereby the abrasion is prevented and dust aggradation phenomenon is adjusted ont side and top of the the accessory.
