FIELD: machine building.;SUBSTANCE: invention is related to the field of valve building, in particular to check valves, and is intended for prevention of back flow in gas, oil lines of high pressure, in power engineering. Check valve with axial direction of flow comprises external body with ...
通常这种阀门是自动工作的,在一个方向流动的流体压力作用下,阀瓣打开;流体反方向流动时,由流体压力和阀瓣的自重合阀瓣作用于阀座,从而切断流动。 The check valve works by allowing only the medium to flow in one direction and flow in the opposite direction. Usually the valve works automatically and open...
The flow-limiting check valve has the advantages that the flow-limiting check valve is installed in the water pump pressure outlet when a plurality of pumps are used in parallel, limits the working flow of the water pump, prevents pump stopping and back flowing, and is compact in structure,...
This valve has only one check valve unit of the type used in Fig. 1, the piston being restrained from movement in the bore of the plunger in a direction away from the unit by a pin. A spring loaded check valve without ports is used instead of the second flow control check valve. ...
An annular valve seat is provided on the outlet side of the intermediate passage upon which the ball rests when the valve is in a first or closed position. The valve ball is arranged to move to a second position to open the valve to the flow of fluid through the valve. The outlet ...
