Abstract

The utility model relates to a water cutoff protector for a laser cooling device. On the ground that an electromagnetic valve and a copper tubing electrode are adopted and the water cutoff protector is arranged on the outlet end of the laser cooling device, the utility model fundamentally overcomes the problem that the magnetic floats are used as primary elements of the water cutoff protector for causing the insufficient reliability. Tests show that the utility model has the advantages of simple structure, simple manufacture, and high reliability; the utility model is suitable for various laser cooling devices needed with the water cutoff protection.

Description

Water cutoff protector for laser cooling device
The utility model belongs to the no water protector of water circulation cooling device, and it is particularly suitable for doing the usefulness of laser water cooling water cut-off protection.
Laser tube is the parts of most critical in the laser.Must adopt the recirculated water cooling for the laser tube that needs the recirculated water cooling.If occur cutting off the water supply in start process or the water composite cooling pipe in the water underfill laser, the near laser tube that makes breaks.Therefore water cut-off protection is most important to the water-cooled laser of needs.The prior art no water protectors that have magnetic float that adopt more; its working condition can be summarized as: start working when water pump and draw water; because the effect of current pushes up magnetic float to the position that dry-reed relay is housed; because the effect of magnetic force makes the dry-reed relay adhesive, to making control circuit allow laser works.Otherwise when water pump quits work (or flow action disappear or cut off the water supply), magnetic float breaks away from dry-reed relay, and the contact on the dry-reed relay disconnects, and control circuit quits work laser, thereby realizes water cut-off protection.Following problems appears in this class no water protector regular meeting: because no water protector is installed in before the water inlet end, and water pipe breaks or leaks between laser tube and glass tube, laser tube can't obtain normal recirculated water cooling and damage (1).(2) shut down after, the water in the laser cooling water pipe since action of gravity with reflow tank.Because of the head of laser can move vertically, water inlet is higher than delivery port when moving up, and water inlet is lower than delivery port when moving down.When water inlet is higher than delivery port, cooling water is failed to be full of cooling water pipe and is just flowed out from delivery port, and this moment, start caused that then laser tube breaks.(3) after the time of one section of machine operation; impurity increases in the water; or owing to the reason of machining; at this moment magnetic float may be stuck in (or adhering to) glass tube (or guide rail) a certain section; and do not move up and down, so that lose water cut-off protection effect (Chinese patent application number be that the no water protector that is adopted in 87207855 also exists this problem) with current.(4) in addition, some laser takes to install two little Metallic rod as electrode in one section glass tube, because Metallic rod is little, in case oxidation and rusting, resistance also changes thereupon between two electrodes, makes the protective device cisco unity malfunction.
Therefore, the purpose of this utility model just is to design a kind of safe and reliable and be applicable to the no water protector of laser water-cooling apparatus.
For this reason, technical solution of the present utility model is, designed no water protector is made up of an electromagnetically operated valve, two copper pipe electrodes, water inlet pipe, outlet pipe and two tube connectors that are used to be connected.And press: the order of water inlet pipe, electromagnetically operated valve, tube connector, copper pipe electrode, tube connector, copper pipe electrode and outlet pipe couples together these seven parts.Two tube connectors and inlet tube and outlet tube all adopt non-conducting material.The shared power supply of water pump on electromagnetically operated valve and the cooling device is to reach the purpose of working simultaneously.Two copper pipe electrodes are connected with the control circuit of control laser power supply, and the water power resistance reduces or underfill water power resistance increases according to being full of between two copper pipe electrodes, realizes that control laser energising work or outage quit work.When leaking or water pump when not working, underfill water between two copper pipe electrodes, the laser outage quits work, and reaches the water cut-off protection purpose.The water inlet pipe of no water protector is connected with the water side of laser cooling water pipe, and outlet pipe links to each other with water tank.When shutting down, electromagnetically operated valve closes in addition, because the effect of atmospheric pressure; water in the laser cooling water pipe is not because of in the former of gravity thereby the inflow water tank; therefore need only when starting shooting for the first time, make the water inlet end of laser be lower than the water side, after this will be full of water forever in the cooling water pipe of laser.Adopt copper pipe to make electrode, cracky not, water is big with pipe face contact-making surface, resistance value have change under water or the anhydrous situation very stable.
The no water protector of making by technical solution provided by the utility model that is used for laser cooling device; overcome the existing in prior technology deficiency fully; have simple in structure; make easily; good reliability, and be suitable for being installed on the water-cooling apparatus of any laser that needs water cut-off protection and use.
Fig. 1 is a kind of laser cure apparatus schematic diagram of prior art.[ 1 ] is head among the figure, and [ 2 ] are laser, and [ 3 ] are water tank, and [ 4 ] are the water inlet of laser cooling water pipe, and [ 5 ] are laser cooling water pipe delivery port, and [ θ ] is the head fulcrum, and head [ 1 ] can move vertically around fulcrum [ θ ], wherein "

Fig. 2 is the cooling device connection diagram of no water protector of the present utility model and laser.Wherein " → " represents water (flow) direction, and each numeral is represented respectively among the figure: the water inlet [ 10 ] of water pump [ 7 ], laser cooling water pipe [ 6 ], no water protector [ 8 ], water tank [ 9 ], cooling water pipe [ 6 ], the delivery port [ 11 ] of cooling water pipe [ 6 ].
Fig. 3 is inner each the parts connection layout of the utility model no water protector.
It is as follows to provide the utility model embodiment below in conjunction with accompanying drawing:
With reference to Fig. 3, no water protector of the present utility model [ 8 ] is to be made up of electromagnetically operated valve [ 12 ], two copper pipe electrodes [ 14,16 ], two tube connectors [ 13,15 ], outlet pipe [ 18 ] and water inlet pipe [ 17 ].And be linked in sequence by above-mentioned technical solution is described.With reference to Fig. 2, the water inlet pipe [ 17 ] of no water protector [ 8 ] is connect the delivery port [ 11 ] of laser cooling water pipe [ 6 ], outlet pipe [ 18 ] water receiving case [ 9 ].In addition, the water inlet water receiving case [ 9 ] of water pump [ 7 ], the delivery port of water pump [ 7 ] connect the water inlet [ 10 ] of laser cooling water pipe [ 6 ].Electromagnetically operated valve [ 12 ] in the no water protector [ 8 ] uses a power supply jointly with water pump [ 7 ].Two copper pipe electrodes [ 14,16 ] link to each other with the control circuit of control laser.Its working condition is: in the time of water pump [ 7 ] energized, electromagnetically operated valve [ 12 ] is also opened immediately, current flow along " → " direction, this moment two copper pipe electrodes [ 14,16 ] be full of water (being also to be full of water in the tube connector [ 15 ]) between, resistance value between the two copper pipe electrodes [ 14,16 ] also descends thereupon, makes control circuit control laser works.When occurring leaking or cutting off the water supply, the interior underfill water of tube connector [ 15 ], the resistance value between the two copper pipe electrodes [ 14,16 ] increases, and control circuit control laser quits work, and realizes water cut-off protection.When shutting down, electromagnetically operated valve [ 12 ] closely cuts out, because the atmospheric pressure effect, the laser cooling water pipe is full of water in [ 6 ] all the time.
