Problems solved by technology

[0002] There are two methods for flushing or car washing of existing sanitary ware, one is to flush directly with water, and use a large amount of water to flush the sanitary ware at high speed to take away the dirt with the water, which consumes a lot of water and increases the amount of sewage treatment
Recently, compressed air is sprayed into the water pipe to form a gas-liquid two-phase flow, and its volume flow rate is higher than that of pure water. Although it can save water when used to flush sanitary ware, a compressed air system must be added at the same time to flush sanitary ware. bring extra trouble

Embodiment Construction

[0008] figure 1 It is also a diagram of a swirl injection type washing water saver for flushing toilets. When the water supply valve connected to the swirler nozzle is opened, the pressure water enters the swirl nozzle 1, accelerates in the converging nozzle 7 and then enters the equal-diameter channel 8, where a high-speed swirling jet is formed through the swirler 2 It flows into the injection gun and sprays to the mixing chamber 5. Due to the high speed and high rotation, the vacuum in the mixing chamber is caused, and the air flows into the mixing chamber through the injection hole 3 and mixes with the rotating water flow to form air-water Two-phase flow, since the mixing chamber itself is also a converging nozzle, this two-phase flow flows through it, is accelerated again, enters the equal-diameter channel at the lower part of the injection gun, and mixes with the air injected into the mixing chamber, The gas-water two-phase flow is further increased in gas content, and ...

Abstract

The swirl-flow injection washing water-saving device is formed from swirl-nozzle, swirler and multi-stage injector. Said swirler is mounted in ismetric channel after negative throat nozzle so as to produce rotary jet flow. The injector can be connected after swirl-nozzle, and can inject air into the injector, and can mix the air with rotary water flow so as to form air-water two-phase flow to increase volume flow quantity of fluid and form lots of discontinuous dispersion phase, and said above-mentioned air-water two-phase flow can be jetted from water-saving device for washing car body and other equipment to be cleaned, and can attain the goals of saving water and raising washing effect.

Description

Technical field: [0001] The patent of the present invention relates to a swirling jet type washing water saver, which is mainly used in sanitation fields such as car washing, toilet flushing, roads, tracks, bridges, river beaches, beaches, and house exterior walls. Background technique: [0002] Existing sanitary ware flushing or car washing have two ways, one is directly flushing with water, flushing the sanitary ware with a large amount of water at a high speed to take away the dirt with the water, which consumes a large amount of water, and also increases the sewage treatment capacity. Recently, compressed air is sprayed into the water pipe to form a gas-liquid two-phase flow, and its volume flow rate is higher than that of pure water. Although it can save water when used to flush sanitary ware, a compressed air system must be added at the same time to flush sanitary ware. cause extra trouble. Invention content: [0003] In order to overcome the deficiencies of the pri...
