Description

Предметом изобретени   вл ете  лрисиособление дл  запирани  и регулировки расхода жидкости, пара и газа со шпинделем, выполненным в виде дифференциального поршн .The subject of the invention is a device for locking and adjusting the flow of fluid, steam and gas with a spindle made in the form of a differential piston.

Приспособлени  (запорные вентили) дл  запирани  и регулировани  расхода наход 1цихс  в резервуарах или трубопроводах жидкости, пара или газа обн еизвестны. Дл  предотвращени  утечкп 1эегул1 руемои или запираемой среды они имеют сальники, которые при эксплуатаили, особенно при запирании среды под высоким давлением, нуждаютс  в частом подт гивании. При несвоевременном иодт гива нии происходит утечка запираемой среды и не удаетс  сохранить необходимое посто нное давление в резервуарах или трубопроводах.Fixtures (shut-off valves) for locking and controlling the flow are found in the tanks or pipelines of a liquid, vapor or gas that are known. In order to prevent leakage of the flares or the locked medium, they have glands that, when used, especially when locking the medium under high pressure, need frequent tightening. In case of untimely iodization, a lockable medium leaks and it is not possible to maintain the necessary constant pressure in the tanks or pipelines.

Описываемое приспособление отличаетс  тем, что давление в сальниковоГ набивке создаетс  дифференциальным поршнем, роль которого выполн ет ишиндель. Это давление обеспечивает посто нное уплотнение сальника, в результате чего отпадает потребность в его частой регулировке . Устран етс  утечка запираемой среды через уплотнение, а в резервуарах или трубопроводах сохран етс  посто нное давление.The described device is characterized in that the pressure in the packing of the gasket is created by a differential piston, the role of which is performed by the chisel. This pressure ensures a constant sealing of the gland, as a result of which there is no need for its frequent adjustment. Leakage of a lockable medium through the seal is eliminated, and constant pressure is maintained in tanks or pipelines.

На чертеже показан продольный разрез приспособлени , предназначенного дл  запирани  и регулировки расхода воздуха в воздухопроводе , и сечение по АА.The drawing shows a longitudinal section of a device for locking and adjusting the flow rate of air in an air duct, and a section along AA.

Самоустанавливаюишйс  клапан 1 соединен чекой 2 с запорным винтом 3. Клапан может вращатьс  относительно винта, но чека заставл ет его перемеи1атьс  вдоль оси вместе с винтом. Сальниковое уплотнение 4 зат гиваетс  гайкой 5. Шпиндель 6 выполнен в виде дифференциального поршн . С запорным винтом он соединен хвостовиком квадратного сечени .The self-aligning valve 1 is connected by a check 2 to a locking screw 3. The valve can rotate relative to the screw, but the check causes it to move along the axis along with the screw. The packing 4 is tightened with the nut 5. The spindle 6 is designed as a differential piston. With a locking screw, it is connected by a square shank.

При врашении шпиндел  воротком запориый винт ввертываетс  или вывертываетс  из корпуса, причем происходит закрывание или открывание клапана. Давлением среды шпиндель прижимаетс  в проWhen the spindle is screwed in, the locking screw is screwed in or out of the body, and the valve is closed or opened. The medium pressure of the spindle is pressed in the pro
