The application discloses a double-membrane water treatment system, which comprises a front ultrafiltration assembly and at least one reverse osmosis assembly; the front ultrafiltration assembly is provided with an ultrafiltration water tank; the reverse osmosis assembly is connected to the downstream of the ultrafiltration water tank and is provided with a water tank; the water production side and the concentrated water side of the reverse osmosis assembly are respectively connected to a discharge flow path; a shunt device provides a first discharge flow path and a second recovery flow path for flushing water from the reverse osmosis assembly; the first discharge flow path is connected to an external discharge point of the system; the second recovery flow path is connected to the water tank or the ultrafiltration water tank in the system; a control unit receives an operating state signal of the reverse osmosis assembly to control the shunt device to selectively guide the flushing water to the first discharge flow path or the second recovery flow path; in a flushing state, the shunt device guides the flushing water to the second recovery flow path; and in a chemical cleaning state, the shunt device guides the flushing water to the first discharge flow path. The scheme realizes recycling of high-quality flushing water and improves the recovery rate of the system.

This invention discloses a disc spring tension and compression testing device, relating to the technical field of spring testing equipment. The invention includes a base frame, with a first and second receiving boxes placed on opposite sides of the base frame. Supports and bases are installed at the front and rear ends of the base frame, respectively, and abutments are installed on both sides of the rear end of the supports. It also includes a protective assembly comprising a fixed ring mounted on the upper surface of the support and a protective sleeve connected to the rear end face of the fixed ring. The other end of the protective sleeve is located on the front end face of a moving ring. A cylinder is mounted on the top of the front end face of the moving ring. An air port on the outer wall of the cylinder is connected to two connecting pipes via a three-way pipe. The other end of the connecting pipe is connected to an air outlet pipe via a pipe joint. The other end of the air outlet pipe is located on the top of the outer wall of the air cylinder. A rubber pad is slidably installed inside the air cylinder. This disc spring tension and compression testing device provides good protection for workers, has a wide range of applications, and improves material feeding efficiency.
