Example Embodiment

[0016] This application is based on a general inventive concept, with two related but they can independently solve the technical problems to be solved, and a number of inventions with very significant beneficial effects. That is to say, the independent pressure reducing and draining valve is one of the main structural features and invention points of the independent pressure storage and energy saving flushing water tank, and it can be used independently or for other purposes. And the drainage valve in this pressure storage energy-saving flushing water tank is not only the pressure reducing drainage valve in the independent item, but also the installation structure that can be realized by various non-reducing drainage valves, that is, the pressure reducing and conventional Non-decompression type, and there are multiple structural forms of direct start and indirect start. The indirect valve activation has permanent magnet valve activation device type, flow pressure valve activati...

Abstract

The invention discloses a pressure-storing and energy-saving washing tank and a pressure-reducing water drain valve. A pressure-reducing valve element is sleeved in a pressure-reducing cover to form the pressure-reducing water drain valve 2 and mounted on a water outlet 1B of a water tank. A valve rod 2C is connected with the pressure-reducing valve element 2A or is provided with a labor-saving lever mechanism 5. A permanent magnet or flowing pressure or electromechanical valve starting device is connected with the pressure-reducing valve element through the valve rod for indirect starting. A flow-storing flexible bag 7 and an air inlet and outlet hole or an air regulating valve can be arranged at the inner end of the water tank. A slow-draining and water-storage-supplement chamber 9 can be arranged at the outer end of the water outlet. The pressure-reducing valve needs few starting power and can directly start or indirectly start by the aid of a low-energy-consumption power device. The problems that existing pressure-storing washing tanks and straightway water drain valves are large in stress, difficult in starting, large in water drain pressure drop, high in cost and the like are solved. The pressure-reducing water drain valve has the advantages of low starting power, large water drain pressure, large flow, small pressure drop, capability of supplementing water storage, cleanness and water saving in washing, low cost, maintainability, low usage cost and the like.

Description

technical field [0001] The invention relates to various sanitary ware and drainage valves, in particular to flushing water tanks and flushing valves of various toilets. Background technique [0002] In the existing various fluid pressure storage and discharge device technologies, there are problems such as large pressure drop during discharge, large pressure on the valve, and difficulty in starting. Problems such as large pressure and high cost. The above-mentioned problems include various existing sanitary ware, especially toilets, squatting pans, and sewage flushing pressure-storage flushing water tanks and straight-through flushing valves in toilet pits. The water inlet, or smaller than the cross-sectional area of ​​the flow channel, causes the water body to diffuse in the flow channel and cause the pressure to drop, which cannot achieve the flushing effect that is cleaner and more water-saving than the non-pressure storage flushing tank. question. For example, the pre...
