(54) ВИНТОВОЙ КЛАПАН(54) SCREW VALVE

ле 4 и запорном органе 5, образовьшают клапанную щель 18 (фиг. 2) с постепенно увеличиваюшрйс  площадью поперечного сечени  за счет разностн углов при вершине конусов седла и запорного органа. В варианте исполнени  клапана, представленном на чертежах, угол при вершине конуса седла составл ет 100°, аугол при вершине конуса запорного органа - 90°. Ось симметрии клапанной щелн в открь1том положении клапана совпадет с осью 19 входного 2 и выходного 3 патрубков корпуса. Запормый орган 5 вьшолнен с направл юшим коническим BbKTjniOM 20, угол прк вершчне конуса которого больше угла при вершине конуса, образующего поверхность 17.At 4 and the locking body 5, a valve slit 18 (Fig. 2) is formed with a gradually increasing cross-sectional area due to the difference in the angle at the apex of the cones of the saddle and the locking body. In the embodiment of the valve shown in the drawings, the angle at the apex of the cone of the saddle is 100 °, and the angle at the apex of the cone of the closure member is 90 °. The axis of symmetry of the valve click in the open position of the valve will coincide with the axis 19 of the inlet 2 and the outlet 3 of the nozzles of the housing. The feed-in organ 5 is made with a directed tapered BbKTjniOM 20, the angle of which is greater than the angle at the apex of the cone forming the surface 17.

Дл  закрыти  клапана поворачивают маховик 14; сообща  осевое перемещение верхнему участку 10 разрезного шпиндел , а также через толкатель 11 и мембрану 9 - и нижнему участку 6 с запорным органом 5, вход щим в плотный контакт с седлом 4, прерьюа  поток жидкости, проход щей через клапан,To close the valve turn the handwheel 14; jointly axial movement of the upper section 10 of the split spindle, as well as through the pusher 11 and the membrane 9, and the lower section 6 with the locking member 5 entering into tight contact with the saddle 4, interrupting the flow of fluid passing through the valve,

Запорный орган 5 со шпинделем 6 перемещаетс , в открытое положение под воздействием пружины 8 и силы давлени  жидкости во входном патрубке 2.To open the valve, the flywheel 14 is turned in the opposite direction, raising the split spindle 10. The locking member 5 with the spindle 6 is moved to the open position under the influence of the spring 8 and the pressure force of the fluid in the inlet 2.
