FIELD: physics. ^ SUBSTANCE: stop valve consists of the case (1) joined to a water filling pipe joined to float (17) valves (5) and gadget for the alarm system about achievement of necessary water level. In the case the holes (13) connected with its vacuity are executed, and the valve (5) with travel possibility between basic and persistent saddles is located. For exception of action of a water stream on a float (17) and its connecting devices, the float (17) is related to an upper of a rod of the valve. The rod is executed with passage possibility through it waters to the gadget for the alarm system after contact of the valve to the thrust saddle. ^ EFFECT: construction simplification, increase of stability of stop valve operation. ^ 13 cl, 11 dwg |
