An automatic water drain switch of an engine comprises a switch body, a switch shell, a center sleeve, a push rod and a spring, wherein the switch body and the switch shell are connected to form a valve cavity, a water inlet and a water outlet are respectively formed in the switch shell and the switch body and are communicated with the valve cavity, the center sleeve is positioned in the valve cavity, one end of the push rod is positioned in the center sleeve like a piston, the other end of the push rod is abutted against the inner wall of the switch shell, a temperature sensing medium is arranged in the center sleeve, the spring is abutted between the center sleeve and the switch body, a rubber plug is installed at one end of the center sleeve, and the rubber plug is opposite. After the invention is adopted, automatic water discharge can be realized when the temperature of the cooling water of the engine is close to zero centigrade, and the cooling water of the engine can be not filled with antifreeze, thereby reducing the use cost and simultaneously avoiding worrying about the problem that the engine is frozen and damaged due to temperature mutation or forgetting to discharge water.
Description
Technical field
The present invention relates to the engine cooling based part, especially the motor cock of water drain.
Background technique
Existing motor adopts water cycle to force the type of cooling usually, therefore removing needs to be equipped with water tank, water pump, outside the component such as valve, also cooling jacket must be set on engine cylinder-body, cooling jacket, water tank and be connected in motor and water tank between water pipe constitute the cooling water circulation loop of a sealing, lower position at cooling water circulation loop also will be provided with a cock of water drain, change cooling water or under other situation that need discharge water, utilize this cock of water drain that the cooling water in the circulation loop is put only, traditional cock of water drain is an obstruction that is arranged on the engine cylinder-body normally, the aperture that discharges water that will be connected with cooling jacket is blocked at ordinary times, and handy instrument is pulled down it in the time of need discharging water.
At all seasons, the employed ambient temperature of motor differs greatly, northern especially true in China, for prevent motor and water tank winter not by bursting by freezing, the antifreeze liquid of generally will in cooling water, annotating, but antifreeze liquid is more expensive, can increase user cost; Someone is for for the purpose of saving, the antifreeze liquid of can in cooling water, not annotating, but before ambient temperature reduces, ahead of time the cooling water in motor and the water tank is bled off.Yet in use, unavoidable existence is met change in weather, is forgotten the situation that discharges water or forget filling antifreeze liquid in cooling water, makes motor suffer unnecessary loss because of bursting by freezing.
Summary of the invention
The purpose of this invention is to provide a kind of automatic drainage switch of engine, it can realize during near zero degrees celsius discharging water automatically at cooling water temperature, thereby effectively avoids motor by bursting by freezing.
For achieving the above object, automatic drainage switch of engine provided by the invention includes Switch main body, switch case, central sleeve, push rod and spring, after linking to each other with switch case, Switch main body constitutes valve pocket, be respectively equipped with water intake on switch case and the Switch main body and water outlet is connected with valve pocket, central sleeve is positioned at valve pocket, one end of push rod is positioned at central sleeve as piston, the other end of push rod and switch case inwall butt, temperature sensing medium is housed in the central sleeve, spring is connected between central sleeve and the Switch main body, one end of central sleeve is equipped with plug, and this plug is relative with water outlet on the Switch main body.
The temperature sensing material that temperature sensing medium adopts paraffin class to have the characteristic of expanding with heat and contract with cold.Under the normal condition, Switch main body is subjected to the elastic force of the pressure of temperature sensing medium more than or equal to spring, and the plug of Switch main body end is blocked the water outlet on the Switch main body, though cooling water is in the normal circulation state through valve pocket.When cooling water temperature is reduced near zero degrees celsius, temperature sensing medium shrinks, and Switch main body is subjected to the elastic force of the pressure of temperature sensing medium less than spring, and Switch main body moves to the push rod direction, thereby open water outlet, the cooling water in the circulation loop is discharged from water outlet through valve pocket.
As a kind of preferred embodiment, central sleeve leads by the internal chamber wall of Switch main body, and is provided with axial guiding gutter at the central sleeve outer circumferential face, has so both guaranteed that central sleeve moves steadily, can make cooling water waltz through valve pocket again and flow to water outlet.
As another preferred embodiment, the external diameter of Switch main body is designed to vary in size two sections, small outer diameter section is provided with outside thread, and lays seal ring in the tool withdrawal groove of screw thread processing.During assembling, can directly be installed on the position of engine cylinder-body corresponding to water cavity by the screw thread on this small outer diameter section, mounting or dismounting are convenient.
After adopting the present invention, can realize discharging water automatically during at engine cooling water temperature near zero degrees celsius, the antifreeze liquid of can not annotating in the cooling water of motor, thus user cost reduced, also needn't worry because of temperature jump simultaneously or forget the problem that the motor that causes of discharging water is damaged by bursting by freezing.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the present invention mainly is made of Switch main body 1, switch case 2, central sleeve 3, push rod 4 and spring 5, Switch main body 1 is connected the back with switch case 2 in end thread and constitutes valve pocket 6, Switch main body 1 is provided with water outlet 7 and communicates with valve pocket 6, and switch case 2 is provided with water intake 8 and communicates with valve pocket 6.
Temperature sensing medium 9 among the present invention can adopt the temperature sensing material with the characteristic of expanding with heat and contract with cold, as paraffin.
Referring to Fig. 3, during use, the present invention can be contained in the position of engine cylinder-body 13 corresponding to cooling water chamber, also can be installed in lower somewhere, arbitrary position in the whole cooling water circulation loops such as water tank 14, cylinder body water inlet pipe 15 or cylinder body outlet pipe 16.The part that dotted line institute frame is lived among Fig. 3 promptly is an automatic drainage switch of the present invention.
Under the normal condition, Switch main body 1 is subjected to the elastic force of the pressure of temperature sensing medium 9 more than or equal to spring 5, and the plug 10 of Switch main body 1 end is blocked the water outlet on the Switch main body 17, though cooling water is in the normal circulation state through valve pocket 6.When cooling water temperature is reduced near zero degrees celsius, temperature sensing medium 9 shrinks, and Switch main body 1 is subjected to the elastic force of the pressure of temperature sensing medium 9 less than spring 5, and Switch main body 1 moves to push rod 4 directions, thereby open water outlet 7, the cooling water in the circulation loop is discharged from water outlet 7 through valve pocket 6.As seen, the present invention can realize discharging water automatically during near zero degrees celsius at engine cooling water temperature, the antifreeze liquid of can not annotating in the cooling water of motor, thus user cost reduced, also needn't worry because of temperature jump simultaneously or forget the problem that the motor that causes of discharging water is damaged by bursting by freezing.
