Description

Push type heating installation discharge valve

Technical Field

The utility model relates to a flow control valve controlling means technical field, concretely relates to push type heating installation discharge valve.

Background

The heating exhaust valve is used for releasing air pockets generated in a heat supply system and a water supply pipeline by a user, and is suitable for being applied to northern areas with severe climatic environments. The gas-water heater is widely applied to water distributors, heating radiators and floor heating, and when gas is generated in a system, the gas can climb upwards along a pipeline due to low density of the gas and finally gathers at the highest point of the system. The vent valve is typically mounted at the highest point of the system. When the gas enters the exhaust valve cavity and is gathered at the upper part of the exhaust valve, the pressure rises along with the increase of the gas in the valve, when the gas pressure is higher than the system pressure, the gas can lead the water surface in the cavity to fall, the buoy falls along with the water level, and the exhaust port is opened; after the gas is exhausted, the water level rises, the buoy also rises along with the water level, the exhaust port is closed, and the conventional heating exhaust valve cannot be closed quickly during exhaust due to the structural problem and is sometimes unreliable in closing, so that water leakage is serious during exhaust.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an open and close rapidly, can the effective control displacement, close reliable push type heating installation discharge valve, be realized through following scheme.

In order to realize the above purpose, the utility model discloses a technical scheme be: the utility model provides a push type heating exhaust valve, includes first valve body, second valve body, valve rod, valve gap, valve clack, first valve body and second valve body threaded connection are fixed, and are equipped with first sealing washer between the two, second valve body and valve gap threaded connection are fixed, and are equipped with the second sealing washer between the two, valve rod one end passes seal ring, second valve body, valve gap, third sealing washer, gland nut centre bore, stop nut's centre bore in proper order to and with valve cap threaded connection, the valve rod other end and valve clack threaded connection, be equipped with seal ring between valve gap and the second valve body, be equipped with the spring between valve cap and the valve gap, stop nut installs between valve cap and gland nut, gland nut outer wall and valve gap centre bore inner wall threaded connection, the third sealing washer is installed between gland nut and valve gap, be equipped with the exhaust hole on the second valve body casing, be equipped with the dust cap on the exhaust hole, dust cap and exhaust hole (outer wall threaded connection, be equipped with the dust cap sealing washer between dust cap and the exhaust hole outer wall, second valve body () centre bore diameter is greater than the valve rod diameter and has the exhaust gap between.

Further, the sealing washer is connected with the valve clack in an adhesive mode.

Further, the cross-sectional shape of the third sealing ring is a right trapezoid.

Further, one of the inner angles of the third seal ring of the right trapezoid is 60 degrees.

Further, one end of the spring is abutted against the valve cover, and the other end of the spring is abutted against the valve cap.

Further, the diameter of the central hole of the second valve body is larger than the diameter of the valve rod by 3 mm.

The technical effects of the utility model reside in that: when pressing down the valve cap, valve clack and seal ring leave the second valve body and open, open the size by stop nut control, the exhaust gap is opened between second valve body and the valve rod this moment, it is external that gaseous passes through exhaust gap and exhaust hole discharge valve body, become rivers when the air current, loosen the valve cap, the valve clack resets under the effect of spring, the exhaust gap between second valve body and the idle pole is closed thereupon, cut off the water this moment, no longer there is water to discharge, and the heating installation water pressure is big more, the exhaust gap is closed inseparabler, such push type heating installation discharge valve has improved the practicality of device greatly, open and close rapidly, it is reliable to close, high durability and convenient use, and strong application performance.
