Abstract

The invention relates to a high-low pressure automatic switching atomization nozzle. The high-low pressure automatic switching atomization nozzle is specifically a nozzle which can automatically switch work states for ensuring atomization effect of a cooling medium under high pressure and low pressure circumstances. The high-low pressure automatic switching atomization nozzle comprises a housing,a rotary nozzle, a disc spring and a mixing nozzle, wherein the mixing nozzle is connected with the front end of the housing through a thread, a Venturi-like mold cavity is formed in the mixing nozzle, the front end of the rotary nozzle is inserted into the middle of the mixing nozzle, a spacer bush is arranged on the upper portion of the mixing nozzle, a rotary mold cavity and a taper runner areformed in the rotary nozzle, a seal bevel A is arranged on the side edge of the bottom of the rotary nozzle, a seal bevel B is arranged on the front side of the rotary nozzle, a spacing bush is arranged between the side face of the rotary nozzle and the mixing nozzle, the disc spring is arranged between the spacing bush and the bottom of the rotary nozzle, the tail of the rotary nozzle is connected with a rotary hole plate, a check ring and a graphite annulus are further arranged on the upper portion, on the outer circle side of the rotary nozzle, of the disc spring, the tail of the housing isconnected with a flange, a runner hole is formed in the front end of the housing and communicates with an annular space in an inlet of a flow hole, and slant cutting openings are evenly distributed in the rotary hole plate.

Description

technical field [0001] The present invention relates to an atomizing nozzle with automatic switching between high and low pressure, which relates to a nozzle that can automatically switch the working state of the desuperheating medium to ensure the atomization effect under the condition of high pressure and low pressure, and is especially suitable for working conditions where the pressure of the desuperheating medium is unstable. , automatically switch to the best atomization state. Background technique [0002] In the occasions where steam turbines, power steam stations, etc. produce superheated steam, it is often necessary to reduce the temperature of the superheated steam for downstream equipment to use. warm medium. When faced with superheated steam at different temperatures, most of them use the nearest desuperheating medium for desuperheating, but the pressure of the desuperheating medium does not necessarily meet the corresponding desuperheating requirements; sometim...
