Abstract
The utility model relates to a water pressure auto-control switch for a water purifier, which belongs to the technical field of a water pressure controller of the water purifier. The problem the utility model is to solves is to provide a water pressure auto-control switch for a water purifier, which can automatically lower the water pressure when the water pressure is higher than a certain pressure. The technical scheme which solves the technical problem of the utility model is that the utility model comprises a rotating water valve, a pressure sensor, a transmission device and a bottom plate, wherein a transmission head is arranged on a rotating knob head of the rotating water valve. A water inlet of the pressure sensor is connected with a water outlet of the rotating water valve and is communicated with an inlet of the water purifier, a sensing element is connected with a transmission rod and the sensing element drives the transmission rod to move under the function of the water pressure. The transmission device comprises a transmission plate and a return spring, an oblate hole is arranged on the transmission plate and the transmission plate is sheathed on the transmission head of the rotating water valve by the oblate hole. One end of the return spring is arranged on an outer shell of the pressure sensor, and the other end is arranged on the transmission plate. The utility model is applied to the water purifier. The utility model has the advantages that when the water pressure is larger than the prescribed value, the water pressure can be automatically reduced and the bursting of the water purifier can be avoided. Therefore, the safe operation of the water purifier is ensured.
Description
Technical field
The utility model belongs to the hydraulic controller technical field of water purifier.
Background technology
The prior art water purifier is depressed and can normally be moved at normal water, and weak point is that the pressure that bears of its plastic casing is limited, if hydraulic pressure surpasses certain limit, just plastic casing can explosion, water purifier promptly can not use.
Summary of the invention
Technical problem to be solved provide a kind of in water purifier hydraulic pressure be higher than the hydraulic pressure automatic control switch that can reduce the water purifier of hydraulic pressure under the certain pressure situation automatically.
The technical scheme that solves its technical problem is as follows: the hydraulic pressure automatic control switch of water purifier comprises rotation water valve, pressure sensor device, transmission mechanism and base plate; Rotation water valve and pressure sensing are put and are contained on the base plate; On the knob head of rotation water valve driving head is housed, the water-in of the logical water purifier of outlet of rotation water valve and the sensing device water-in of pressure sensor device; Pressure sensor device comprises shell, sensing device water-in, sensing member and transmission rod, and sensing member is connected with transmission rod, and sensing member drives the transmission rod moving linearly under the effect of hydraulic pressure; Transmission mechanism comprises driver plate and returning spring, it is the flat round hole of circular arc that two ends are arranged on the driver plate, the transmission rod of pressure sensor device is connected with driver plate, driver plate is enclosed within on the driving head of rotation water valve with its flat round hole, the rotation water valve is in open mode at ordinary times, when driver plate is moved downward by the original position, the center of circle that makes driving head center on rotation water valve knob clockwise rotates, to rotate water valve is turned down gradually by the fully open position, until complete off-position, returning spring one end is contained on the shell of pressure sensor device, and the other end is contained on the driver plate.
The rotation water valve is in open mode at ordinary times.When opening running water switch, water flows out to water purifier by the rotation water valve, feed the sensing device water-in of pressure sensor device simultaneously, if hydraulic pressure surpasses prescribed value, sensing member in the pressure sensor device is moved down by water pressure pushing drive transmission rod, transmission rod promotes the driver plate motion, and rotation water valve knob is rotated to clockwise direction, and current are turned down until closing fully.Hydraulic pressure in the water purifier can reduce, and can explosion; When the hydraulic pressure of water inlet pipe was decreased to normal value, returning spring set back sensing member by transmission mechanism, and will rotate water valve and retract original position, recovered normal water supply.
Pressure sensor device can adopt the piston-type pressure sensing device, and sensing member is a piston.
Pressure sensor device can also adopt the diaphragm type pressure sensor device, and sensing member is a diaphragm.
Beneficial effect: the utility model is applied to water purifier and other need regulate the hydraulic pressure part.Beneficial effect is during greater than prescribed value, can reduce hydraulic pressure automatically at hydraulic pressure, avoids the water purifier explosion, thereby guarantees the safe operation of water purifier.
