FIELD: machine building.SUBSTANCE: control valve contains body with inlet and outlet. Outlet is formed by single radial hole in the valve body made in form of disk with valve seat. Said seat is located on the valve body between inlet and outlet, and has the valve channel. The said valve channel connects the inlet and outlet with sealing element, that is properly located on the control element to close of the valve channel, and with control device. Said control device is made to move the control element such that to open and to close the valve. The valve seat at the outlet side has peripheral shoulder passing axially from the support surface towards the hole. Upon the valve opening the valve body direct flow-around is terminated. The shoulder has recess corresponding to the sealing element for its installation.EFFECT: possibility of valve use at higher pressures upon simultaneous decreasing of the metal erosion.7 cl, 3 dwg |
