Quantitative pressure suction valve

The invention discloses a quantitative pressure suction valve which comprises a valve body. A water inlet and a water suction outlet are formed in the two sides of the valve body, a water pressure diaphragm piece is fixed in the upper end of the valve body, and a center flow guide hole is formed in the center of the water pressure diaphragm piece. A sealing column used for blocking the center flow guide hole is pressed at the top of the water pressure diaphragm piece, a downward pressing piece used for pressing the sealing column downwards is installed in an upper cover, an air pressure diaphragm piece is installed in the lower end of the valve body, and an upward ejecting piece used for ejecting the sealing column upwards is installed at the upper end of the air pressure diaphragm piece or between the air pressure diaphragm piece and the sealing column. According to the quantitative pressure suction valve, use of multiple plastic parts such as a water tank and a floating ball is eliminated, and a large amount of material cost can be saved for enterprises and the country; no floating ball is used, and the problems of the defects of congenital air leakage, water inflow and sinking of floating balls are solved; use of a large part of rubber pipes can be reduced, and peculiar smells can be obviously reduced; the quantitative pressure suction valve can rotate by 360 degrees in all directions and do not leak water; the quantitative pressure suction valve can be suitable for various RO reverse osmosis machine types; and pollution caused by long-time contact of water and air can be eradicated.

Garbage water classification system

The invention relates to a garbage water classification system and a garbage water classification method. The method comprises the following steps that 1, garbage in a storage module is subjected to bag breaking through a garbage feeding module and is uniformly transmitted to a subsequent processing module; 2, small particulate matters in the garbage are treated through sieving and water flushing; 3, water is filled into a separation tank by a heavy object separation module water supply pump, heavy objects naturally sink for separation, light-weight garbage suspending above the water layer overflows out of the heavy object separation tank along with water flows, and metal heavy objects are selected from settled inorganic heavy objects through a magnetic separation device; 4, light-weight garbage overflowing from the heavy object separation tank by a wind separation module is conveyed to a wind separation device through a conveying belt, and a fan blows away lighter garbage; and 5, organic matters, combustibles, plastics and the like are shorted through a manual sorting module. The water participates in the whole garbage classification system, so the system has the advantages of high efficiency, no environment pollution, good work environment, simple production line, controllability, reliability and the like in the garage classification aspect.

Deodorant energy-saving trash can

The invention discloses a deodorant energy-saving trash can. A can body is included, and the upper side wall of the can body is rotationally connected with a cover plate; magnetic attracting strips attracted mutually are embedded in the lower side wall of the cover plate and the upper side wall of the can body; a photovoltaic plate is installed on the cover plate, and a storage battery connected with the photovoltaic plate through a photovoltaic converter is further installed on the cover plate; and a liquid storing pipe and an ultraviolet lamp are installed on the lower side wall of the coverplate. The deodorant energy-saving trash can has the beneficial effects that solar energy is collected, and energy consumption is reduced; when trash in the trash can is fermented and generates heatand generates bad smell, a moving rod is driven to move due to expanding of an expanding medium, and connection between the ultraviolet lamp and the storage battery is completed; due to work of the ultraviolet lamp, sterilizing is performed in the can and foul gas is pyrolyzed, and the bad smell is reduced; and meanwhile, when the cover plate is opened, extracting type movement is achieved, so that part of the bad smell enters a U-shaped pipe and is adsorbed and eliminated through active carbon, and it is prevented that the bad smell overflows.
