Abstract

The utility model relates to a water box spattering-proof cover for a water cooling evaporation type engine, which is a protecting cover used for preventing cooling water from spattering out caused by vibration. The spattering-proof cover can prolong the usage time of the cooling water in a water box, prevent hot water from spattering out to burn a driver, and can be installed on a cover of a water filling hole of the water box of an S195 engine, and the installation and the disassembly are simple and convenient. The original water filling mode is not changed, and the service performance of the original engine is not affected.

Description

Water-box spattering-proof cover for water-cooling evaporation type engine

The utility model is the protective housing that a kind of cooling water that prevents water-cooled evaporative type engine water tank outwards splashes.

Place, existing water-cooled evaporative type engine water tank filler does not prevent that cooling water from spattering device outward.When engine luggine, particularly this motor is installed on the tractor, when on rugged road, jolting, cooling water outwards splashes to such an extent that go through very much evil, make the cooling water in the water tank reduce soon, so not only need frequent additional cooling water, increase driver's labor intensity, the hot water that spills the simultaneously driver that burns easily.If tractor long-distance running, water source are difficult to look for, winter, supplementing water was just more difficult, outwards splashed so prevent cooling water, for the protection normal working of engine, alleviated driver's labor intensity, guaranteed that the safety of travelling is a matter of great account feelings.

The purpose of this utility model is separated exactly and is never allowed cooling water spatter outward, prolongs cooling water service time, alleviates driver's labor intensity, prevents that the hot water that the driver is splashed out from burning.

Owing to have cooling water and steam to exist in the water-cooled evaporative type engine water tank simultaneously, so the splash guard that is added on the engine water tank filler had both required cooling water not spatter, require cooling water simultaneously again outward because the steam that becomes after being heated can successfully be discharged to airspace.

Design principle of the present utility model is: the cooling water motion amount of passing through of splashing in the water tank is big, after it is subjected to resistance, will change the direction of splashing, and it is got back in the water tank again.Steam in the water tank is because the motion amount of passing through is little, be subjected to resistance after, do not change flow direction, steam still can be moving along attached jet, flows to airspace by breach.Go out water-cooled evaporative type engine water tank splash guard according to this principle design.

This splash guard is made up of three parts: guard shield, overhead gage, lower pedal.Wherein overhead gage and lower pedal are staggered up and down in guard shield, and a downward-sloping angle, make to form one " S " type cavity in the guard shield, help the discharge of steam, have prevented that again cooling water from spattering outward simultaneously.

Now the process that realizes with regard to the utility model in conjunction with the accompanying drawings is described further: three parts forming splash guard are guard shield 1, overhead gage 2, lower pedal 3, and all available metal thin plate or exotic material are made.The shape of cross section of guard shield 1 can be the same with the shape of cooling water evaporation formula engine water tank filler cap, and size can be slightly less than the size of filler lid, so that splash guard is directly installed on the filler cap.Overhead gage 2 and lower pedal 3 relative staggered being installed on the inwall of guard shield 1, and become 10 ° with horizontal plane～20 ° of angles.Overhead gage 2 is opened a circular hole at the end near guard shield 1 inwall, and the unsteady scale of not overslaugh of the size water tank in this hole freely rises or descends and is as the criterion.Lower pedal 3 has two row's circular holes at the other end by guard shield 1 inwall, and this two rows circular hole helps steam and discharges.

When the cooling water in the water tank is subjected to vibration when splashing, at first be subjected to stopping of lower pedal 3, the cooling water that a part is splashed is got back in the water tank, the cooling water that another part splashes, be subjected to stopping of overhead gage 2, be blocked the cooling water of returning and fall earlier above the lower pedal 3, again along the slope current recovery tank of lower pedal 3.

Steam in the water tank rises through the bottom of guard shield 1, runs into lower pedal 3, and by the two row's circular holes of lower pedal 3 and the indentation, there of lower pedal 3, continuing to rise runs into overhead gage 2, and the indentation, there by circular hole and overhead gage 2 flows to airspace.

The utility model can prolong more than one times on service time at cooling water than the S195 motor that this splash guard is not housed by proving through test of many times on the S195 engine water tank that is contained in CT-12 type tractor.

The utility model has following accompanying drawing:

Fig. 1 is a water-cooled evaporative type engine water tank splash guard plan view.

Fig. 2 is the utility model plan view.

Fig. 3 is the utility model A-A sectional view.

Wherein 1. be guard shield, 2. are overhead gages, 3. are lower pedals.

The utility model can be directly installed on the Water-cooled evaporation type engine water tank filler by guard shield 1 rim of the mouth and cover. Install, remove simple and convenient. Do not change and originally added the water mode. Do not affect the serviceability of former machine.

Claims
