CS249778B1 - Change-over valve with mechanical drive for constant volume dosing device - Google Patents

Abstract

The caching refers to a switching valve s mechanical drive for small dosing dosing of liquids for analytical measurement procedures. The solution is essential limiting time to preparation and final operation, thereby achieving substantial operation increasing the utilization rate of the dispenser. Special valve body division in connection with special mechanical design the powertrain makes it possible to accelerate performing side surgery. The changeover valve (5) consists of a valve valve body (6) made by processing cold-alloyed PTBB, from the head (7) and the attachment portion (8). Valve the valve body (6) has a conical shape part (9) and cuff (10). Connecting the part (8) has two conical holes (11, 12), the cylinder (2) has two channels (15, 14) and the cuff (10) has three holes (15, 16, 17). Switching device (5) assembly from switching body (19), from changeover fork (20) with two swinging pins (25, 26) and the handwheel (21). Valve body (6) toggle valve (5) and toggle the devices (5) are connected to each other by means of a coupling device (18). Angle between the two conical openings (11, 12) The part (8) is 150 °, the angle between the two channels (15, 14) of the cylinder (2) have the same v.elokbst, angle between first and second the opening (15, 16) of the cuff (10) is 75 ° a the angle between the second and third holes (16, 17) the cuff (10) is < 15 > O.
