Description

Technical Field

[0001] The utility model relates to the technical field of SMT surface mounting assembly lines, in particular to an inductive automatic switch water valve. Background Art

[0002] Currently, during BTU maintenance, authorized maintenance personnel must use a key to open the faucet above the chemical cleaning solution collection pool to draw water. When the BTU maintenance personnel finish cleaning, they must immediately close the faucet and remove the key to prevent unauthorized personnel from using it at will and prevent domestic water from flowing into the chemical collection pool.

[0003] However, this operation also has disadvantages, especially when the BTU maintenance personnel have not finished cleaning all the parts and need to temporarily leave the sink, they must immediately use the key to turn off the faucet. If the faucet is not turned off in time, it will lead to a waste of water resources and an unnecessary increase in sewage in the chemical collection tank, increasing the cost of chemical sewage treatment.

The faucet is connected to a water supply pipeline, and a water valve body is provided on the water supply pipeline. A power supply is respectively connected to a relay and a photoelectric sensor. A signal line of the photoelectric sensor is connected to a coil of the relay to control the opening and closing of a normally open point of the relay according to a signal of the photoelectric sensor. The relay is electrically connected to the water valve body to control the opening or closing of the water valve body by opening and closing of a normally open point of the relay.

[0007] In a preferred embodiment of the present invention, the faucet is a lockable faucet.

[0008] In a preferred embodiment of the utility model, the water valve body adopts a solenoid valve.

[0009] In a preferred embodiment of the present invention, the power source includes a battery and / or a power socket.

[0010] The beneficial effect of the utility model is that the switch of the solenoid valve is controlled by the induction signal of the sensor to avoid misoperation by irrelevant personnel, which can not only better save water, but also effectively control the discharge of chemical sewage to prevent domestic water from being polluted by chemicals.

[0013] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1 , the utility model embodiment includes:

[0015] An inductive automatic switch water valve comprises a faucet 1 arranged on a clean water tank, a water supply pipeline 2, a water valve body 3, a photoelectric sensor 4, a relay 5 and a power supply 6.

[0016] A photoelectric sensor is provided on the faucet, and the faucet is connected to a water supply pipeline in which a water valve body is installed. A power supply is respectively connected to a relay and a photoelectric sensor, and a signal line of the photoelectric sensor is connected to a coil (voltage) of the relay to control the opening and closing of a normally open point of the relay according to a signal of the photoelectric sensor. The relay is electrically connected to the water valve body to control the opening or closing of the water valve body by opening and closing of the normally open point of the relay.

[0017] The sensing signal of the photoelectric sensor is used to control the closure of the water valve body, so that the water stops when people leave, so that domestic water is not polluted by chemicals, which can better save domestic water and efficiently control the generation of chemical wastewater.

[0018] When a BTU cleaning worker stands in front of the cleaning sink and is within 300mm of the photoelectric sensor, the solenoid valve is triggered to open, and the faucet supplies water to clean the equipment components. When the worker walks out of the sensing range of the sensor, the solenoid valve automatically shuts off the water source immediately, which serves as a second insurance for controlling water use.

[0019] Further preferably, the faucet is a locking faucet.

[0020] Further preferably, the water valve body adopts a solenoid valve.

[0021] Further preferably, the power supply includes a battery and / or a power socket, and the socket is connected to a 24V power supply to provide a 24V working power supply to the solenoid valve, the sensor and the relay.

[0022] Working principle description:

[0023] 1. When the authorized maintenance personnel uses the sink to clean the equipment parts that have been cleaned by chemicals, the authorized personnel walks to the sink (within 300mm of the photoelectric sensor), uses the key to open the faucet to get water, and the photoelectric sensor senses that the personnel is in front of the sink. The photoelectric sensor signal line becomes 0V, the 13 and 14 coils on the relay are energized, the normally open point 5 and the common terminal 9 are attracted, the solenoid valve is energized, the water valve opens, and water flows out of the faucet.

[0024] 2. When the person turns around and leaves, the photoelectric sensor does not detect anyone in front (within 300mm), the photoelectric sensor signal line becomes 24V, the 13 and 14 coils on the relay lose power, the normally open point 5 and the common terminal 9 are disconnected, the solenoid valve loses power, the water valve is closed, and the faucet is cut off.

[0025] The beneficial effect of the inductive automatic water switch valve of the utility model is that the switch of the electromagnetic valve is controlled by the inductive signal of the sensor, and on the premise of avoiding irrelevant personnel to use the chemical cleaning tank and add key authorization, water is better saved and the generation of chemical sewage is efficiently controlled.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
