A water supply device capable of controlling water level accurately comprises a water feeding pipe, a water discharge pipe and a water tank; the water tank is connected with the water feeding pipe and the water discharge pipe and is internally provided with a water level control valve subassembly; the water level control valve subassembly comprises a cavity internally provided with a sealing gluepad, a floating tube and a supporting pillar; the water pressure area at the bottom of the sealing glue pad is greater than that of the upper plane thereof; the sealing glue pad can be moved upwards and downwards by means of the pressures of upper and lower water; the supporting pillar is fixed above the floating tube; a release hole is formed at the bottom of the valve cavity at the position corresponding to the supporting pillar; a water inlet and a water outlet are formed on the valve cavity, and the water inlet is connected with the water feeding pipe. The device has simple and skilful design, accurate liquid level control effect, less stored water and highly accurate water feeding effect. The product by using the design of the device can be ultra-minimized and thinned. The raw material can be saved a lot, the cost can be reduced, and the product reliability is high. The invention can be widely applied to the product with water level to be controlled such as water boiler and waterdispenser, thereby having great social and economical benefits.

The invention relates to the field of heat exchange, and discloses a novel micro-flow plate. The micro-flow plate is formed by compounding two plate pieces and comprises an inner side medium flow channel and two outer side heat exchange surfaces; the inner side medium flow channel is composed of a distribution channel, a collecting channel and net-shaped crossed micro heat exchange channels; a first medium enters the micro-flow plate and is distributed by the distribution channel and then enters the net-shaped crossed micro heat exchange channels to be sufficiently turbulent, heat is exchangedbetween the two outer side heat exchange surfaces and the second medium on the outer side of the micro-through plate when flowing through the micro heat exchange channels; a heat conduction componentused for increasing the heat exchange area of the second medium is arranged on the outer side heat exchange surface of at least one of the two plate pieces. The micro heat exchange channels are uniformly distributed in the whole novel micro-through plates in a net-shaped staggered mode and ensures that the first medium fully utilizes the heat exchange surface; further, a heat conduction part is arranged on the outer side heat exchange surface of at least one plate piece, the heat exchange area of the second medium is increased through the arrangement of the heat conduction component, and themaximization of the heat exchange effect is facilitated.

A toilet seat water economizer of the invention comprises an upper component provided with a sewage port, a toilet adapter groove and an outer tube for a sewage pipe adapter groove; an upper transitional suit with a crumpled neck which is formed by narrowly contracting on the upper side, wherein the neck matches with the sewage port; a barrel body with the upper side connected to the lower side ofthe transitional suit and with the lower side narrowly contracted into a drainage port; at least one pair of springs with one end fixed with the outer tube and with the other end fixed with the barrel body; a drainage port switch cover pivoted on the barrel body and matched with the drainage port; a switching cover sustaining device arranged in the lower part of the inner wall of the external tube; a guiding device arranged on the inner wall of the outer tube to connect the barrel body and the outer tube; a gas valve composed of a valve rod with a valve door and a ventilating socket with ventilating holes, wherein the valve rod is fixed on the barrel body, the ventilating socket is time-delayed set on the outer wall of the sewage port, the valve door matches with the ventilating holes, and the ventilating holes are communicated with the sewage port. The invention has the advantages of simple structure and convenient installation, and can save water.

The invention relates to the field of heat exchange, in particular to water, oil, CO 2 A device for heat exchange between similar or non-homogeneous media such as air, refrigerant, etc. The micro-pass plate is composed of an inner medium flow channel and two outer heat exchange surfaces. The inner medium flow channel is composed of a distribution channel, a collection channel and a network of intersecting micro heat exchange channels. The inlet end of the micro heat exchange channel is connected with the distribution channel, and the outlet end is connected with the collection channel. The micro-pass plate is compositely formed by two plates, and the periphery of the two plates and the raised joint in the middle are tightly combined to form a whole. The network-shaped interlaced micro-channels and numerous recombination points evenly distributed on the entire plate surface make the medium in the flow channel form turbulent and swirling flow, and exchange heat with the outside through the thin plate quickly and efficiently. The micro-pass plate has many advantages such as ultra-thin, good mass production processability, high heat exchange efficiency, small volume, and low cost.

The invention provides a rapidly lifting net cage, which belongs to the technical field of net cages. The present invention comprises net cage body and several lifting devices, and several lifting devices are arranged on the net cage body, and lifting device comprises first piston cylinder, first piston, second piston cylinder, piston rod, driving mechanism, water inlet and outlet mechanism and Inlet and exhaust mechanism, the first piston cylinder is fixed on the cage body, the first piston is slidably arranged in the first piston cylinder, the second piston cylinder is fixed below the first piston cylinder, and the piston rod is slidably arranged in the second The upper end of the piston cylinder and the lower end of the piston rod are fixed with a second piston, the upper end of the piston rod is fixedly connected with the first piston, and the second piston divides the interior of the second piston cylinder into an upper chamber and a lower chamber, and the driving mechanism can push the first The piston slides up and down, the water inlet and outlet mechanism can control the water inlet and outlet of the water storage chamber, and the inlet and exhaust mechanism can control the inlet and outlet of the upper chamber and the lower chamber. The invention can quickly raise and lower the net cage according to the sea conditions, and improves the ability of resisting wind and waves.

The application discloses a water supply system optimization method and a community water supply system adjustment method. The water supply system optimization method includes: obtaining basic information of the water supply system supplying the community; and obtaining the optimized high-level water tank volume of each high-level water tank node according to the basic information of the community. The water supply system optimization method of this application obtains the optimized high-level water tank volume of each high-level water tank node based on the basic information of the water supply system supplying the community. This application can obtain new optimization results at any time according to the change of the basic information of the community, and use this optimization result to Adjust the actual water storage capacity of each high-level water tank, so that compared with the existing technology, it can provide a more suitable water supply environment for the community. water, leading to problems of deteriorating water quality.
