62211 results about "Water pipe" patented technology

Water pipes are pipes or tubes, frequently made of polyvinyl chloride, ductile iron, steel, cast iron, polypropylene, polyethylene, copper, or lead, that carry pressurized and treated fresh water to buildings, as well as inside the building.

Combined steam and gas turbine engine with magnetic transmission

In a combined steam and gas turbine engine cycle, a combustion chamber is made durable against high pressure and enlarged in length to increase the operation pressure ratio, without exceeding the heat durability temperature of the system while increasing the fuel combustion gas mass flow four times as much as the conventional turbine system and simultaneously for greatly raising the thermal efficiency of the system and specific power of the combined steam and gas turbine engine.Water pipes and steam pipes are arranged inside the combustion chamber so that the combustion chamber can function as a heat exchanger and thereby convert most of the combustion thermal energy into super-critical steam energy for driving a steam turbine and subsequently raising the operation pressure ratio and the thermal efficiencies of the steam turbine cycle and gas turbine cycle. The combustion gas mass flow can be also increased by four times as much as the conventional turbine system (up to the theoretical air to fuel ratio) and the thermal efficiency and the specific power of the gas turbine cycle are considerably increased.Further, the thermal efficiency of the combined system is improved by installing a magnetic friction power transmission system to transmit the power of the system to outer loads.

Ultrasonic waterjet apparatus

An ultrasonic waterjet apparatus (10) has a mobile generator module (20) and a high-pressure water hose (40) for delivering high-pressure water from the mobile generator module (20) to a hand-held gun (50) with a trigger and an ultrasonic nozzle (60). An ultrasonic generator in the mobile generator module (20) transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer (62) which vibrates to modulate a high-pressure waterjet flowing through the nozzle (60). The waterjet exiting the ultrasonic nozzle (60) is pulsed into mini slugs of water, each of which imparts a waterhammer pressure on a target surface. The ultrasonic waterjet apparatus (10) may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus (10) performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect. A nozzle with multiple exit orifices or a rotating nozzle (76) may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient. A water dump valve (27) and controlling solenoid are located in the mobile generator module (20) rather than the gun (50) to make the gun lighter and more ergonomic.

Atomizing dish washing machine

The invention discloses a domestic atomizing dish washing machine and a commercial atomizing dish washing machine. When dishes are washed by the domestic atomizing dish washing machine, a drawer-type dish basket with a door lock opened is pulled out of the dish washing machine. Dirty tableware is placed in the drawer-type dish basket, the drawer-type dish basket is pushed into the dish washing machine, a running button is pressed, and tap water flows into an inner tank through a water inlet electromagnetic valve and then flows into a water tank. After the water tank is full, the water inlet electromagnetic valve is closed. A fan is started, a water pump is started, and a power supply heating pipe is connected. Air blown by the fan passes through an air outlet condensation pipe, an ozone generation device, an electric heating wire and an opened and connected air outlet electromagnetic valve to enter an air outlet pipe, and then the air passes through an upper air pipe to be blown out from an air outlet of a capillary air pipe in a conical nozzle of a rotary spray arm. Water pumped by the water pump is filtered by a filter screen to enter a water outlet pipe through a water outlet electromagnetic valve and finally enters the conical nozzle of the capillary air pipe to be mixed with the air blown out from the air outlet of the capillary air pipe to be sprayed out from the conical nozzle in atomizing mode to wash dishes. The atomizing dish washing machine further has the functions of drying, sterilizing and automatically putting in dish washing powder.
