Manual diaphragm valve
ActiveCN115038901BArbitrary adjustmenteliminate individual differencesDiaphragm valvesOperating means/releasing devices for valvesStructural engineeringDiaphragm valve
The present invention provides a manually operated diaphragm valve that maintains compactness through a simple construction while simultaneously allowing for setting the valve body's opening and closing range. This design is unaffected by individual differences in the valve's internal shape, ensuring sufficient flow rate when fully open, and also allowing for arbitrary adjustment of the fully open flow rate. The valve body 1 includes a valve body 12 assembled inside a main body 10 and a main shaft 13 threaded into the main body 10 in a lifting motion, separating the valve body 12 from the valve seat 14. A handle 2 is mounted above the valve body 1 for manually rotating the main shaft 13. Near the upper part of the valve body 1, a fully open position adjustment mechanism 20 is provided. This mechanism restricts the rotation of the handle 2 on the fully open side, setting the upper limit of the flow rate of the valve body 12 when fully open.
