The invention discloses a mine high-flow-rate high-pressure water depressurization device. By using the device, a cavern does not need to be arranged for depressurization, the occupied space for installation is small, the investment is small, the durability is good and the production and operation costs are reduced. The device is provided with a high-pressure chamber body, a high-pressure chamber, a low-pressure chamber body and a low-pressure chamber, wherein pressure gauges are arranged on the high-pressure chamber body and the low-pressure chamber body, a left flange plate is arranged at the inner end of the high-pressure chamber body, a filter is embedded in the left flange plate, a compression spring is arranged in the filter, a boundary disc is arranged between the left flange plate and a right flange plate, a plurality of oil guide holes are formed in the circumferential end surface of the boundary disc, a lubricating oil cylinder is arranged on the left side of the boundary disc, a small hydraulic cylinder is arranged therein, a lubricating chamber is arranged between the lubricating oil chamber and the small hydraulic cylinder, an oil filling hole is formed in the lubricating oil cylinder, the lubricating chamber is communicated with the oil guide holes, a large hydraulic cylinder is arranged on the right side of the boundary disc, and a T-shaped piston is arranged in the small hydraulic cylinder and the large hydraulic cylinder. The mine high-flow-rate high-pressure water depressurization device is mainly applicable to mine deep well depressurization water supply systems.
Description
technical field [0001] The invention relates to a mine large-flow high-pressure water decompression device. Background technique [0002] At present, in order to reduce the water pressure of the deep wells of coal mines, it is necessary to design special chambers for construction, so that the water is stored in the chambers, so as to reduce the distance between the water surface and the bottom of the well and achieve the purpose of reducing the water pressure. Such a technical solution needs to occupy a large space, and a large amount of expenses must be invested, thereby increasing production and maintenance costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-flow high-pressure water decompression device for mines that does not require a chamber, occupies a small space for installation, saves investment, reduces production costs and is durable. [0004] In order to solve the above-mentioned technical...
