Description

TECHNICAL FIELD

[0001] The utility model relates to water supply equipment field, concretely relates to a kind of aircraft drinking water supply device. BACKGROUND

[0002] The aircraft service pit is mainly used to provide maintenance services, such as power supply, gas supply, refueling and oil draining, water supply and drainage, etc., for various aircrafts in hangars or on the apron, and is widely installed on the apron due to its high operating efficiency, safety and other advantages.

[0003] In order to supply water to the aircraft, an aircraft drinking water supply device is installed on the aircraft service pit. A drinking water pipeline is pre-buried in the apron, which includes a buried water supply pipeline for supplying drinking water and a buried circulation pipeline for keeping the drinking water in a flowing state in the pipeline. The drinking water supplied by the buried water supply pipeline comes from a drinking water machine room capable of filtering and disinfecting the drinking water. The buried circulation pipeline can keep the water in the pre-buried drinking water pipeline in a flowing state of live water at all times. The drinking water in the buried circulation pipeline will flow into the drinking water machine room and be filtered and disinfected by the drinking water machine room. The existing aircraft drinking water supply device mainly injects drinking water into the water tank of the aircraft through a hose connected to the buried water supply pipeline when supplying water to the aircraft. It is difficult to control emergency situations that may occur during the water supply process, such as rupture of the buried water supply pipeline and leakage of the hose.

[0004] Therefore, the existing aircraft drinking water supply device has the problem of difficulty in controlling emergency situations that may occur during the water supply process. SUMMARY

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the existing technology and provide an aircraft drinking water supply device that is easier to control emergency situations that may occur during the water supply process.

[0006] To solve the above technical problems, the utility model provides an aircraft drinking water supply device, which includes a first pipeline, a second pipeline, and a valve assembly capable of controlling the flow state of drinking water in the first pipeline and / or the second pipeline. One end of the first pipeline is connected to the buried water supply pipeline, and the other end of the first pipeline is detachably connected to the water tank through a first hose. A manual ball valve is installed on the end of the first hose close to the water tank. One end of the second pipeline is connected to the buried circulation pipeline, and the other end of the second pipeline is connected to a second hose. A quick connector is installed on the end of the first hose close to the first pipeline for connecting to the end of the second hose away from the second pipeline.

[0007] As a further improvement of the utility model: the valve assembly comprises a first underground lever gate valve, a first electric ball valve and a check valve which are sequentially installed on the first pipeline from right to left; the valve assembly further comprises a second underground lever gate valve and a second electric ball valve which are sequentially installed on the second pipeline from right to left; the first pipeline and the second pipeline are communicated through a communication pipe, and a third underground lever gate valve is installed on the communication pipe.

[0008] As a further improvement of the utility model: a pulse turbine flowmeter and a pressure reducing valve are sequentially installed on one end of the first pipeline close to the first hose from the side far away from the first hose to the side close to the first hose. The pulse turbine flowmeter can count the total water consumption of the whole water supply circuit and upload to the airport control system for billing information processing.

[0009] The utility model discloses a kind of aircraft drinking water supply devices, which is easy to control emergency in water supply process.

[0010] The device includes a first pipeline in communication with a buried water supply pipeline, a second pipeline in communication with a buried circulation pipeline, and a valve assembly installed on the first pipeline and / or the second pipeline to control the flow state of drinking water in the first pipeline and / or the second pipeline. In the event of an emergency during water supply, the flow state of drinking water in the first pipeline and / or the second pipeline can be changed by controlling the valve assembly, reducing losses and risks, and lowering maintenance costs.

[0011] Meanwhile, the first pipeline and the first hose of the device form a water supply circuit, and the quick connector, the second hose, and the second pipeline of the device form a circulation circuit. The circulation circuit allows drinking water in the first hose to flow into the buried circulation pipeline for circulation, solving the problem of residual drinking water in the hose after water injection in existing devices. This avoids wasting drinking water that has not been injected into the water tank in the first hose or gradually becoming stagnant water that does not meet drinking water standards. Thus, the drinking water can always circulate in the pipe, helping to ensure water safety.

[0012] In addition, by installing a manual ball valve on the end of the first hose close to the water tank, the staff only needs to detachably connect the first hose to the water tank and open the manual ball valve to complete the water supply. This is simple and fast, and can effectively improve the water supply efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0023] For example, Figure 1 , Figure 2 , Figure 3As shown, the utility model provides a kind of aircraft drinking water supply device including first pipeline 1, second pipeline 2 and the valve assembly 3 of being able to control the flow state of drinking water in first pipeline 1 and / or second pipeline 2 being arranged on first pipeline 1 and second pipeline 2;Valve assembly 3 includes first dark rod gate valve 301, first electric ball valve 302, check valve 303 being installed on first pipeline 1 in order from right to left;Valve assembly 3 further includes second dark rod gate valve 304, second electric ball valve 305 being installed on second pipeline 2 in order from right to left;First pipeline 1 and second pipeline 2 are connected by communicating pipe 6, and third dark rod gate valve 306 is installed on communicating pipe 6.Third dark rod gate valve 306 keeps closed state, and first dark rod gate valve 301, first electric ball valve 302, second dark rod gate valve 304 and second electric ball valve 305 all keep open state when using.When water supply circuit or circulation circuit has problem, first dark rod gate valve 301 or second dark rod gate valve 304 can be closed quickly, and emergency shutdown operation is carried out, and if first dark rod gate valve 301 or second dark rod gate valve 304 has problem, first electric ball valve 302 or second electric ball valve 305 can also be closed to carry out emergency shutdown operation.Check valve 303 prevents water backflow, and protects the safety of first pipeline 1.

[0024] As Figure 1 、 Figure 2 、 Figure 3 As shown, one end of first pipeline 1 is connected with buried water supply pipeline, and the end of first pipeline 1 away from buried water supply pipeline is connected with water tank through first hose 4;Pulse turbine flowmeter 101 and pressure reducing valve 102 are installed on the end of first pipeline 1 close to first hose 4 from the side away from first hose 4 to the side close to first hose 4 in order.

[0025] As Figure 1 、 Figure 2 、 Figure 3 As shown, manual ball valve 401 is installed on the end of first hose 4 close to water tank;Connector 403 for detachable connection with the interface of water tank is installed on the end of first hose 4 close to water tank, and connector 403 can avoid the situation that first hose 4 shakes and deviates from the interface of water tank during water conveying.Mechanical flowmeter 404 is installed on the part of first hose 4 between quick connector 402 and manual ball valve 401, and mechanical flowmeter 404 facilitates staff to clearly observe the flow condition of first hose 4.

[0026] As Figure 1 、 Figure 2 、 Figure 3As shown, one end of the second pipeline 2 is connected with the buried circulation pipeline, and the other end of the second pipeline 2 is connected with the second hose 5, and the first hose 4 is provided with a quick connector 402 on the end close to the first pipeline 1 for connecting with the other end of the second hose 5.

[0027] The working principle of the utility model is as follows: initially, the third gate valve 306 keeps closed, the first gate valve 301, the first electric ball valve 302, the second gate valve 304 and the second electric ball valve 305 keep open.

[0028] Water flows into the first pipeline from the buried water supply pipeline, and flows into the first hose 4 after flowing through the first gate valve 301, the first electric ball valve 302, the check valve 303, the pulse turbine flowmeter 101 and the pressure reducing valve 102.

[0029] After the airplane is parked, the connector 403 is quickly inserted into the interface of the airplane water tank, and the drinking water in the first hose 4 continues to flow through the quick connector 402 and the mechanical flowmeter 404 to the manual ball valve 401, and the staff opens the manual ball valve 401, so that the drinking water continues to flow into the water tank through the connector 403 in the first hose 4.

[0030] The staff can observe the water flow displayed by the mechanical flowmeter 404, and when the water supply circuit leaks, breaks or the like, the first gate valve 301 or the first electric ball valve 302 is closed to perform emergency closing operation on the water supply circuit.

[0031] After the water supply is completed, the connector 403 is quickly pulled out of the interface of the airplane water tank, and the manual ball valve 401 is closed to stop the water supply, and because the check valve 303 can prevent the drinking water from flowing back from the first hose 4 to the first pipeline 1, therefore when the drinking water in the first hose 4 remains at the quick connector 402, it will flow into the second hose 5 from the quick connector 402, and then flow into the second pipeline 2, and then flow into the buried circulation pipeline after flowing through the second electric ball valve 305 and the second gate valve 304, and finally flow into the drinking water machine room, and then flow into the buried water supply pipeline after being treated, and if the circulation circuit leaks, breaks or the like, the second gate valve 304 or the second electric ball valve 305 can be quickly closed to perform emergency closing operation on the circulation circuit.

[0032] When the water supply circuit of the device needs to be checked or maintained, the first electric ball valve 302 and the second electric ball valve 305 are closed, and the third gate valve 306 is opened, so that the water in the first pipeline 1 flows into the second pipeline 2 through the communication pipe 6, and finally flows into the buried circulation pipeline, and the water in the first hose 4 also flows into the second pipeline 2 from the quick connector 2, and finally flows into the buried circulation pipeline, so that the drinking water in the device can flow into the buried circulation pipeline as much as possible to participate in circulation.

[0033] It should be noted that the utility model is not limited to the specific structures shown in the drawings in the above embodiments, and various changes can be made thereto within the knowledge possessed by those of ordinary skill in the art.
