The utility model discloses a kind of toilet water inlet valve, belong to toilet water inlet valve technical field, including water inlet valve main part;The outside of water inlet valve main part is slidably provided with connecting sleeve, one side of the connecting sleeve is fixedly installed with float cup, the inside of the float cup is provided with adjusting screw rod;Waterway flow divider is fixedly installed at the top of water inlet valve main part, air pressure lever is provided above waterway flow divider, through the linkage cooperation of float cup, adjusting screw rod, air pressure lever and valve core, water tank water level can be accurately perceived and controlled, avoid overflow or water shortage, guarantee toilet flushing effect and water-saving performance, satisfy the water level adjustment demand of different users Convenient installation and maintenance: the thread connection of joint, nut, and the quick clamping structure of clamping block, locking clamping block, make that water inlet valve installation is simple and efficient, when later maintenance, such as replacing valve core, filter screen and the like component, can be quickly disassembled and assembled, reduce maintenance difficulty and time cost.

This invention provides a waste liquid collection and temporary storage system and method under raised floors, including a main collection tank, a backup tank, a pneumatic diaphragm pump, a waste liquid inlet pipe, a waste liquid outlet pipe, a gas phase balance pipe, a connecting pipe, an exhaust pipe, and a liquid level detection device. The main collection tank and the backup tank are located below the raised floor, and the pneumatic diaphragm pump is located above the raised floor. The main collection tank and the backup tank are connected by the gas phase balance pipe and the connecting pipe, respectively. Waste liquid enters the main collection tank through the inlet pipe. The liquid level detection device monitors the liquid level and triggers the pneumatic diaphragm pump to deliver waste liquid. In case of abnormal inflow, the connecting valve is opened to expand the capacity of both tanks, forming a temporary storage space. The system is also equipped with a multi-stage liquid level detection device, a pneumatic ball valve, and an independent control box, possessing automatic control, pressure balancing, and overflow prevention functions. It has a compact structure, is safe and reliable, and can effectively improve the continuous operation capability and emergency buffering capability of the waste liquid collection system under raised floors.

The application relates to a seal structure for an aluminum alloy window sealing edge, in particular to a one-piece seal structure for an aluminum alloy window sealing edge, which has a constant cross section along the length direction. The cross section comprises a base part for fixing the seal structure body for the aluminum alloy window sealing edge, a cavity part provided with a hollow compression cavity, and a sealing part connected with the cavity part. The wall body of the cavity part comprises a pressure-bearing back plate connected with the base part and an elastic arc surface connected with the sealing part. The sealing part comprises a main sealing rib extending from the independent elastic arc surface and a secondary sealing rib arranged below the main sealing rib. The seal structure for the aluminum alloy window sealing edge is firmly fixed with the mounting groove through the above structure design, and when being extruded, the hollow compression cavity is deformed and the main and secondary sealing ribs of the sealing part are cooperated to provide excellent sealing performance and buffering performance, meanwhile, the structure is compact, the installation is convenient, and the sealing reliability and service life of the equipment or component are remarkably improved.
