Y-shaped exhaust gear

Abstract

The invention discloses a Y-shaped exhaust gear and relates to a steam system. The invention provides the Y-shaped exhaust gear which is reasonable in structure, stable in performance and longer in service life. The Y-shaped exhaust gear is provided with an upper cover, a lower cover, an upper diaphragm capsule cover, a lower diaphragm capsule cover, a spring, a limiting plate, a diaphragm, a locating plate, a spherical valve core, a reinforcing ring and a valve seat, wherein the limiting plate is arranged in an alcove at the inner side of the upper diaphragm capsule cover; the spherical valve core is connected with the locating plate; the spherical valve core is connected with the locating plate and the diaphragm; the reinforcing ring is pressed on the outer end face of the lower diaphragm capsule cover; the diaphragm, the locating plate and the spherical valve core are arranged in an outer alcove of the upper diaphragm capsule cover; filling liquid is injected into the inner cavities of the diaphragm and the upper diaphragm capsule cover and is sealed; the lower diaphragm capsule cover is connected with the upper diaphragm capsule cover; the valve seat is arranged in a lower cover hole; the spring is sheathed into an inner cavity of the upper cover; and the other end of the spring is pressed on a convex plate of the upper diaphragm capsule cover. The Y-shaped exhaust gear is reasonable and advanced in structure, small in size, good in performance and long in service life.

Description

technical field [0001] The invention relates to a steam system, in particular to a Y-shaped exhaust device capable of automatically removing cold and hot non-condensable gases. Background technique [0002] The removal of non-condensable gases in the steam system has been changed from the original manual operation to remove non-condensable gases to the current automatic removal of non-condensable gases. Existing devices for automatically removing non-condensable gases include bimetal exhaust devices and bellows-type exhaust devices. Under normal circumstances, the valve core is opened, and the non-condensable gas is discharged through the valve seat hole; when the steam enters, the bimetal sheet in the bimetal strip exhaust device bends and deforms when heated to drive the valve core to close the exhaust valve seat hole, and the membrane After being heated and expanded, the filling liquid in the box-type exhaust device drives the diaphragm to drive the valve core to close t...

AI Technical Summary

Problems solved by technology

The bellows type exhaust device overcomes the shortcoming of the poor sensitivity of the bimetal exhaust device, and is an exhaust device with high sensitivity and stable working performance

[0003] The valve cores of the existing bellows type exhaust devices all adopt a flat sealing structure, which has poor sealing performance and affects the service life
