Abstract

Использование в коммунальном хоз йстве дл регулировани расхода гор чей и холодной воды. Сущность изобретени : конец 11 штока 7 клапана 8 выполнен сферическим с диаметром, большим диаметра штока 7. В коническом гнезде 12 шпиндел 6 размещен конец 11. В стенке гнезда 12 выполнены противолежащие радиальные отверсти 22. Фиксатор 18 выполнен в виде пружинного полукольца с диаметрально загнутыми концами, вставленными в отверсти 22 с возможностью взаимодействи со штоком 7, размещенным с кольцевым зазором дл обеспечени поворота оси штока 7 относительно оси шпиндел 6 на угол, превышающий суммарный перекос уплотн емой поверхности седла 2. 4 ил.Communal use to regulate the flow of hot and cold water. SUMMARY OF THE INVENTION: The end 11 of the stem 7 of the valve 8 is made spherical with a diameter greater than the diameter of the stem 7. The conical seat 12 of the spindle 6 houses the end 11. The opposite radial holes 22 are made in the wall of the socket 12. The latch 18 is made in the form of a spring half ring with diametrically curved ends inserted into the holes 22 with the possibility of interaction with the rod 7, placed with an annular gap to ensure the rotation of the axis of the rod 7 relative to the axis of the spindle 6 by an angle exceeding the total skew of the sealing surface saddles 2. 4 Il.

Claims

Claim

A crane comprising a housing with inlet and outlet nozzles, a seat, a valve with a stem, the end of which is made spherical with a diameter larger than the diameter of the stem, and a spindle with a conical socket in which the spherical end of the stem is located, and a valve stem retainer, characterized in that, in order to increase reliability, opposite radial holes are made in the wall of the spindle socket, the lock is made in the form of a spring half ring with diametrically bent ends inserted into the radial holes of the socket with the possibility of interaction with a valve stem located in a seat with an annular gap to ensure rotation of the stem axis relative to the spindle axis by an angle exceeding the total misalignment of the seat surface being sealed.
