Description
Technical field
The utility model relates to water-aspirator pressure control gear, specifically a kind of Water pump pressure controller being convenient to adjustment critical pressure.
Background technique
Water pump pressure controller is mainly used in the controller on water pump, when water flow is little time i.e. hydraulic pressure open lower than a numerical controller, water pump is started working, when water flow is large time i.e. hydraulic pressure exceed a numerical value so Water pump pressure controller just cut off the electricity supply, water pump is just parked in work.Different according to institute's erection unit, hydraulic demand is different, by adjustment adjusting screw height, controls critical pressure value.Current regulative mode needs the instruments such as other screw-driver, can not complete adjustment work in time.
Model utility content
For solving the problem, the purpose of this utility model is to provide a kind of Water pump pressure controller being convenient to regulate critical pressure.
The utility model for achieving the above object, be achieved through the following technical solutions: the Water pump pressure controller being convenient to regulate critical pressure, comprise housing and the base with joint, in housing, regulator is set, regulator is made up of the first spring and adjusting screw, first lower spring end arranges briquetting, briquetting bottom arranges diaphragm, pressing diaphragm is attached on the pressure-sensitive chamber of base, briquetting contacts the rocker of instantaneously changing device, contact is connected by pull bar with the springboard of instantaneously changing device, the first through hole is offered on the adjusting screw top of housing, the hull outside on the first through hole top arranges adjustment shell, in first through hole, rotating shaft is set, rotating shaft bottom is convex handle, convex handle can coordinate with adjusting screw, rotating shaft is arranged two position limit cycles, between two position limit cycles, resetting block is installed, resetting block is arranged the second through hole, rotating shaft is through the second through hole, resetting block two side bottom arranges the second spring, second spring bottom connects housing, cover top portion is regulated to offer third through-hole, rotating shaft top is through third through-hole, handler is installed at rotating shaft top.
For realizing the purpose of this utility model further, can also by the following technical solutions: described housing sidepiece arranges frame, and frame is provided with secondary adjusting screw, contacts with the springboard of instantaneously changing device.
The utility model has the advantage of: the utility model is when adjusting critical pressure, and rotating shaft pressed, the convex handle of roller end is coordinated with adjusting screw, and rotary motion handle regulates; After adjustment completes, unclamp rotating shaft, under the effect of the second spring, each member reset.The utility model can according to circumstances adjust at any time, and without the need to additionally preparing other instruments, regulative mode is simple and convenient.
