Problems solved by technology

[0002] The upper chamber of the existing hydraulic control valve mostly uses a needle valve to replenish water. When the water supply speed of the needle valve is higher than the drainage speed of the float valve, the pressure in the upper chamber will always be higher than the pressure in the lower chamber, which will keep the main valve in a closed state and cannot to achieve the desired regulation
Moreover, due to the poor response sensitivity of accelerators on the market, it is very likely that the main valve cannot be opened and closed quickly, and the expected effect cannot be achieved.

Abstract

The invention provides an accelerated drainage device and drainage system and relates to the technical field of drainage systems. The accelerated drainage device comprises an accelerator body, a sealseat, a valve seat, a diaphragm, a pressure plate and a cover body. A water inlet and a water outlet are formed in the accelerator body; the valve seat is mounted at the air inlet for controlling on or off of the water inlet and the water outlet; the seal seat is connected to the seal seat; the diaphragm is clamped between the valve seat and the pressure plate, and the pressure plate is located onone side, far from the water inlet, of the valve seat; and the cover body is connected to the accelerator body to fix the pressure plate, the diaphragm and the valve seat between the water outlet andthe cover body. The accelerated drainage device is simple in structure to control on and off of the water inlet and the water outlet by means of a pressure difference between two sides of the diaphragm, and is safe and reliable and high in drainage efficiency.

technical field [0001] The invention relates to the technical field of drainage systems, in particular to an accelerated drainage device and a drainage system. Background technique [0002] The upper chamber of the existing hydraulic control valve mostly uses a needle valve to replenish water. When the water supply speed of the needle valve is higher than the drainage speed of the float valve, the pressure in the upper chamber will always be higher than the pressure in the lower chamber, which will keep the main valve in a closed state and cannot achieve the desired regulation. Moreover, due to the poor response sensitivity of accelerators on the market, it is very likely that the main valve cannot be opened and closed quickly, and the expected effect cannot be achieved. [0003] In view of this, designing and manufacturing an accelerated drainage device, which can effectively achieve the functions of drainage and regulation, is a technical problem urgently in need of impro...
