![]() Valve switch
专利摘要:
A fluid flow control valve having a valve member which is urged away from a cooperating seat by the combined pressures at the valve inlet and outlet and urged towards the seat by fluid pressure prevailing in a chamber which is connected to the valve inlet or outlet, respectively, dependent upon whether an order signal requires the valve to close or to open. Connection between said chamber and the valve inlet and outlet is controlled by an auxiliary valve which in turn is actuated through pressure transmitting lines connected to the inlet and outlet via a switch valve actuated by the order signal. 公开号:SU776574A3 申请号:SU752178150 申请日:1975-10-10 公开日:1980-10-30 发明作者:Берге Лундсгарт Хеннинг 申请人:Данск Индустри Синдикат А/С (Фирма); IPC主号:
专利说明:
Distribution valve cavities. The valve operates as follows: When the regulating element of the control valve 11 is set to the position corresponding to the closed position of the distribution valve, it is higher in Cavity 6 than in cavity 7 and through channels 9, 13, 10 and 12 the medium acts on the regulator 14, which occupies a position in which the high-pressure environment through the channels 9, 15 and 17 enters the cavity 8. Therefore, on. Regulator 2 in this case acts not only the force of the springs 5, but also the high pressure of the medium entering the cavity 8. When a control signal arrives at the opening of the valve, the regulating element of the control valve II takes a position where the connection through the valve 14 of the channels 15 and 17 is stopped, and the channel 17 is connected to the channel 16 and further, with the cavity 7 above the spring 5, the regulator 2 moves toward the opening. The valve is open (see figure 2). When the medium is fed in the opposite direction, i.e. into the cavity 7, the pressure; in the cavity -7 becomes higher than in the cavity 6, the control element of the control valve 14 moves in the opposite direction, while the cavity 8 through the channels 17, 15 and 9 connects to the cavity 6. At This pressure in cavity 8 is equal to low inlet pressure. Valve open If the area of the annular section on the side of cavity 6 and the end surface of regulator organ 2 on the side of cavity 7 are equal to half the cross-sectional area of cavity 8, the pressure of the working medium moving the regulating element 2 by the piston 4 to the left does not depend on the direction of flow of the working medium. . As the medium speed increases, the dynamic pressure on the regulating element increases, it begins to move to the left and the flow area increases, and as the pressure of the working medium decreases, the flow area decreases. , .
