Primary and secondary check valve group of ultra-high pressure water generator

Abstract

The invention relates to a primary and secondary check valve group of an ultra-high pressure water generator. The check valve group comprises an ultra-high pressure water outlet joint body, a water outlet check valve, a water inlet check valve, a left-hand thread pipe pad, a connecting nut, an ultra-high pressure tee joint body, an ultra-high pressure water tank cylinder, a plunger, a water inlet joint body, a flared water inlet nut, a flared water inlet pipe sleeve, a low-pressure water inlet copper pipe and the like. In the invention, a two-grade dual sealing way is adopted, so that the positive conduction and reverse stop of ultra-high pressure water under an ultra-high pressure can be guaranteed effectively; and the opening and closing actions of a valve core are smooth and quick and the time response speed is high, so that the building of the ultra-high pressure of the whole system can be guaranteed and relatively high volume efficiency and relatively high power utilization rate of an ultra-high pressure water generating system can be guaranteed. Therefore, the check valve group is of important significance for the working performance and working reliability of an ultra-high pressure water mist generating system.

Description

technical field [0001] The invention belongs to the technical field of military defense, and relates to the stealth technology of using large-area water mist to resist photoelectric reconnaissance and guided weapons to prevent precision strikes and reconnaissance surveillance, and in particular to a stealth generator for ultra-high pressure water jet water mist. The utility model relates to a sub-mother type one-way valve group of an ultra-high pressure water generating device. Background technique [0002] The working performance of the one-way valve group under ultra-high pressure directly affects the establishment of ultra-high pressure and the volumetric efficiency of the ultra-high pressure water generation system, which plays a key role in whether the ultra-high pressure water jet water mist invisible generator can produce an effective water mist barrier Sexuality. At present, in the design and structure of this type of one-way valve group at home and abroad, the one-...

AI Technical Summary

Problems solved by technology

The disadvantage of the above structure is that the one-way spool with a single integral structure directly affects the dynamic response index of the spool due to its large mass.

The time response process of the valve core in the process of opening and closing is longer. When the valve core is required to open, the water supply is insufficient due to the long opening process; when it is required to close, the long closing process causes reverse water channeling and reduces the volumetric efficiency , and also affects the build-up of pressure
