FIELD: machine building. ^ SUBSTANCE: valving for connection to heating line of heat exchanger of water intake consists of valve of primary circuit regulating flow of liquid-phase coolant in primary circuit of heat exchanger and of valve of secondary circuit which responds to pressure change and regulates flow of process water in secondary circuit of heat exchanger. The valve of the primary circuit is actuated with the valve of the secondary circuit. In an initial position the valve of the secondary circuit has a port; area of the port can be adjusted in the initial position. ^ EFFECT: simplified fabrication of valve. ^ 15 cl, 2 dwg |
