Abstract
The utility model discloses a water supply pressure protecting device for a fresh water car of an airplane. A hydraulic motor pump, a pressure sensor and a flow meter are arranged on a water supply pipeline between a water supply tank and a water tank of the airplane; the water supply pipeline is provided with a two-position three-way solenoid valve; a water return pipeline is arranged between the two-position three-way solenoid valve and the water tank; and the water supply pressure protecting device further comprises a control device used for controlling the two-position three-way solenoid valve and the hydraulic motor pump. The water supply pressure protecting device not only can be used for performing real-time monitoring, but also can ensure safe water supply.
Description
Technical field
The utility model relates to a kind of pressure of supply water fender guard, especially a kind of pressure of supply water fender guard of aircraft clear water car.
Background technology
Aircraft clear water car is generally highly determined for the airline carriers of passengers pressure of supply water by rotating speed, water supply flow and the water supply of water service pump; The rotating speed of water service pump is generally determined by the primary mover rotating speed; And the primary mover rotating speed is generally fixing non-adjustable; So the height of airline carriers of passengers filler is on the low side, perhaps water supply flow is because the situation that pipeline does not freely cause pressure of supply water to raise might be damaged the inner facility of passenger plane.At present, aircraft clear water car does not have the pressure of supply water fender guard.
The utility model content
The utility model provides a kind of pressure of supply water fender guard of aircraft clear water car, controls the speed and the flow of water inlet through pressure sensor and FL/MTR.
The utility model provides a kind of pressure of supply water fender guard of aircraft clear water car, it is characterized in that: on the water supply line between supply tank and the aircraft water tank, HM Hydraulic Motor pump, pressure sensor and FL/MTR are installed.
Preferred scheme is on the water supply line two-position three way magnetic valve to be installed, and is provided with water return pipeline between two-position three way magnetic valve and the water tank.
Preferred scheme is for also comprising control setup, control two-position three way magnetic valve and HM Hydraulic Motor pump.
The pressure of supply water fender guard of the aircraft clear water car that the utility model provides; Add pressure of supply water sensor and FL/MTR; Pressure and flow that monitoring is in real time supplied water; When pressure of supply water exceeds safety value or water supply flow and reaches setting value, cut off Water supply switch valve through electric logic control, stop the operation of supplying water.
Description of drawings
Fig. 1 the utility model constructional drawing;
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model is done further detailed explanation.
Embodiment 1
A kind of pressure of supply water fender guard of aircraft clear water car; It is characterized in that: HM Hydraulic Motor pump (2), pressure sensor and FL/MTR (3) are installed on the water supply line between supply tank (5) and the aircraft water tank (1); Two-position three way magnetic valve (4) is installed on the water supply line; Be provided with water return pipeline (6) between two-position three way magnetic valve (4) and the supply tank (5), for also comprising control setup, control two-position three way magnetic valve and HM Hydraulic Motor pump (2).
Whether control setup HM Hydraulic Motor pump rotates, and the HM Hydraulic Motor pump absorbs water from water tank, pumps the clear water with certain pressure and flow velocity.Setting pressure sensor and FL/MTR on water supply line, pressure sensor monitoring pressure of supply water, FL/MTR statistics output; When pressure of supply water exceeds setting value or water supply flow and reaches setting value; Sensor or FL/MTR provide electric signal, and control setup cuts off the HM Hydraulic Motor pump circuit, and HM Hydraulic Motor stops operating; Perhaps the two-position three way magnetic valve on the water supply line switches water supply direction, makes the clear water water tank that fails to be convened for lack of a quorum.
Above content is to combine structure and the working process of the utility model to its further explain of doing, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
Claims (3)
1. the pressure of supply water fender guard of an aircraft clear water car is characterized in that: on the water supply line between supply tank and the aircraft water tank, HM Hydraulic Motor pump, pressure sensor and FL/MTR are installed.
2. the pressure of supply water fender guard of aircraft clear water car according to claim 1 is characterized in that: on the described water supply line two-position three way magnetic valve is installed, is provided with water return pipeline between two-position three way magnetic valve and the water tank.
3. the pressure of supply water fender guard of aircraft clear water car according to claim 1 is characterized in that: also comprise control setup, control two-position three way magnetic valve and HM Hydraulic Motor pump.
