Abstract
The utility model discloses a water tank cover safety valve for tractor, consisting of a cover body of water tank(1), an air valve(2), a steam valve(3) and a breather pipe(4), wherein, the air valve(2) and the steam valve(3) are arranged inside the cover body of water tank(1); the breather pipe(4) is arranged on one side of the lower end of the cover body of water tank(1); the utility model is characterized in that: an air hole(5) and a safety valve of water tank cover(6) are arranged above the cover body of water tank(1); the safety valve of water tank cover(6) consists of a safety valve seat(7), a safety valve body(8), an exhaust hole(9), an exhaust valve(10) and a spring(11), wherein, the safety valve seat(7) has the lower end connected with the cover body of water tank(1) and the upper end in threaded connection with the safety valve body(8); the exhaust hole(9) is arranged above the safety valve body(8) provided inside with exhaust valve(10) and the spring(11). The water tank cover safety valve for tractor has the advantages of simple structure, convenient operation and safety.
Description
Technical field
The utility model relates to a kind of improvement of tractor tank lid, specifically a kind of tractor tank lid safety valve.
Background technique
Present tractor tank lid is made of water tank lid, air valve, steam valve, breathing pipe, and breathing pipe one end communicates with atmosphere, the other end communicates with the water tank lid, extraneous air overcomes the elastic force of air valve spring, pushes air valve open and enters water tank, and water tank can not damaged because of negative pressure; When water temperature raises, cooling water evaporation in the water tank, steam just promotes the elastic force that steam valve overcomes steam valve spring, opens valve, discharges through breathing pipe, above-mentioned be tractor engine in the water temperature claimed range, the effect that water tank is built air into and gone out steam.But when the tractor overload operation, water tank easily boils, and the case lid of need fetching boiling water behind the boiling of the radiator is arranged steam, arranged boiling water or add cooling water, for preventing to scald finger, when fetching boiling water case lid, cover tank lid with cotton and unscrew and take off, or after water temperature descends, when breathing pipe does not have water or steam ejection, the case lid of fetching boiling water again, the method for the case lid of more than fetching boiling water, its deficiency: the one, with the case lid of manually fetching boiling water, operate cumbersome, the effort, also dangerous; The 2nd, treat that water temperature descends after, the case lid of fetching boiling water again adds cooling water, also loses time very much.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and it is time saving and energy saving to operate, again An Quan tractor tank lid safety valve.
For reaching above purpose, technical solution adopted in the utility model is: this tractor tank lid safety valve, by the water tank lid, air valve, steam valve, breathing pipe constitutes, air valve and steam valve are located in the water tank lid, breathing pipe is located at lower end one side of water tank lid, it is characterized in that above the water tank lid, establishing vent and tank lid safety valve, the tank lid safety valve, by emergency valve seat, Safety valve body, exhaust port, outlet valve, spring is formed, the lower end of emergency valve seat is connected with the water tank lid, the upper end is connected with Safety valve body with screw thread, establishes exhaust port above the Safety valve body, in establish outlet valve and spring.The utility model is also implemented by following measure: described emergency valve seat also is provided with weep hole and waste pipe in the one side.Use the utility model when the tractor boiling of the radiator, steam and boiling water list are discharged from raw water box lid breathing pipe and are had any problem, this moment, steam just promoted the elastic force that outlet valve overcomes spring, open valve, steam and boiling water flow out from exhaust port and waste pipe respectively, or else with the case lid row steam row boiling water of manually fetching boiling water; When needs added cooling water, as long as the little throttle no load running of tractor, the case lid of can fetching boiling water added cooling water.
The beneficial effects of the utility model are: compare with the method for the case lid row steam row boiling water of manually fetching boiling water at present, have simple in structurely, it is time saving and energy saving operate, safe advantage.
Description of drawings
Fig. 1 is the utility model structure cross-sectional schematic.
Embodiment
Make the utility model with reference to accompanying drawing 1.This tractor tank lid safety valve, by water tank lid 1, air valve 2, steam valve 3, breathing pipe 4 constitutes, air valve 2 and steam valve 3 are located in the water tank lid 1, breathing pipe 4 is located at lower end one side of water tank lid 1, it is characterized in that above water tank lid 1, establishing vent 5 and tank lid safety valve 6, tank lid safety valve 6, by emergency valve seat 7, Safety valve body 8, exhaust port 9, outlet valve 10, spring 11 is formed, the lower end of emergency valve seat 7 is connected with water tank lid 1, the upper end is connected with Safety valve body 8 with screw thread, exhaust port 9 is established in Safety valve body 8 tops, in establish outlet valve 10 and spring 11.Described emergency valve seat 7 also is provided with weep hole 12 and waste pipe 13 in the one side.
