Abstract
The utility model relates to a forced pressure-releasing and anti-scalding cover of a water tank. Screws arranged on a spiral press cover is used and precessed from the top to the bottom to forcibly open an air intake valve to cause high-pressure water vapor in the water tank to pass through an intake passage to be discharged reversely. Pressure is leaked by the water tank, the conformity of the internal pressure of the water tank and ambient pressure is ensured when the utility model is lifted, the high-pressure water vapor and boiling water can not spout, and a safety accident is prevented from happening. The forced pressure-releasing and anti-scalding cover of the water tank of the utility model has the advantages of simple structure and safety.
Description
Technical field
The utility model relates to the automobile water tank lid, particularly relates to a kind of pressure row pressure, anti-scald tank lid.
Background technique
Automobile water tank be in the cooling system for motor vehicle important composition partly, tank lid is again the vitals of water tank, is mainly used in to prevent car body in movement process, water overflows and reduces evaporation of water loss in the water tank.The tank lid of prior art as shown in Figure 3, comprise outlet valve, exhaust valve spring, suction valve and inlet valve spring etc., its principle is to utilize the vapor pressure in the water tank to open or close outlet valve and suction valve, emit and the water tank of assurance steam can not be decreased ring, reach 108 ℃ as the boiling point of working as water in the water tank, promptly water vapour pressure reaches the 1.28-1.38 kg/cm
2, outlet valve just can be opened, and lets off steam, and still, under the condition of high temperature, the pressure of cooling system but remains at and is not less than 1.28 kg/cm
2Pressure state under, the tank lid that causes ordinary construction is when opening, still the hot water splash can appear, the scald accident takes place, its main cause is: be higher than external atmospheric pressure in the water tank internal pressure, and do not reach promote exhaust valve spring, when opening the pressure of outlet valve, the operator is when fetching boiling water case lid, steam taking place be mingled with the phenomenon that hot water is outwards gushed, causes personal injury accidents.
Summary of the invention
The purpose of this utility model is at the deficiency of existing tank lid, provides a kind of and can realize pressure release before flip, can not scald people's pressure row pressure, anti-scald tank lid during flip.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pressure row pressure, anti-scald tank lid, comprise spiral cover that is stuck on the tank filler opening and the upward sealing skeleton of fixedlying connected with spiral cover by link, last sealing skeleton lower end socket gland, and with spring is set between the gland, the lower seal skeleton is located at the gland lower end, and can contact with tank filler opening is airtight, have through hole on the described lower seal skeleton, suction valve is located in the through hole, be provided with pressure spring between its upper-end surface and the lower seal skeleton, the above-mentioned sealing skeleton of going up is provided with vent, and tank filler opening is provided with overflow hole, have screw hole on above-mentioned link, Exhaust screw is established within it.
Pressure row pressure of the present utility model, anti-scald tank lid, utilize screw set on the spiral cover, precession from top to bottom, with INO, make the high-pressure water vapor in the water tank pass through the reverse discharge of gas-entered passageway, water tank pressure release by force, guaranteed when flip, the water tank internal pressure is consistent with ambient pressure, does not have high-pressure water vapor, boiled water ejection again, prevents the generation of security incident.
Pressure row pressure of the present utility model, anti-scald tank lid, simple in structure, safe and reliable.
Description of drawings
Fig. 1 forces row pressure, anti-scald tank lid structural representation in normal operation for the utility model;
Fig. 2 forces row pressure, the structural representation of anti-scald tank lid under the row pressure state for the utility model, the steam flow signal when arrow is depicted as exhaust among the figure;
Fig. 3 is the structural representation of prior art tank lid.
Embodiment
Pressure row pressure of the present utility model, anti-scald tank lid, comprise spiral cover 7 that is stuck on the tank filler opening 5 and the upward sealing skeleton 13 of fixedlying connected with spiral cover 7 by link 14, above-mentioned tank filler opening 5 is provided with overflow hole 4, the above-mentioned sealing skeleton 13 of going up is provided with vent 3, last sealing skeleton 13 lower end socket glands 12, and and spring 8 is set between the gland 12, lower seal skeleton 10 is located at gland 12 lower ends, and can with tank filler opening 5 airtight contacts, this structure is to emit too much steam in the water tank: reach the 1.28-1.38 kg/cm for the water tank internal pressure in water tank
2The time, pressure promotes lower seal skeleton 10 and gland 12 is separated from tank filler opening 5, make steam along the space between tank filler opening 5 and the lower seal skeleton 10, overflow hole 4 flows out; Have through hole on the described lower seal skeleton 10, suction valve 6 is located in the through hole, is provided with pressure spring 9 between its upper-end surface and the lower seal skeleton 10, and this structure is in order to prevent that degree of vacuum drops to the 0.01-0.12 kg/cm in the water tank
2The time, water tank is damaged by pressure by atmosphere; In order to strengthen sealing effect, between spiral cover 7 and tank filler opening 5, be provided with seal rubber pad 2, be provided with lower seal rubber cushion 11 between lower seal skeleton 10 and suction valve 6, the tank filler opening 5, the utility model above-mentioned technology the basis on, set up Exhaust screw 1, Exhaust screw 1 is located in the screw hole of link 14.
During normal state, as shown in Figure 1, at this moment, Exhaust screw 1 and suction valve 6 away from, and pressure spring 9 withstands suction valve 6, makes it contact with 11 sealings of lower seal rubber cushion, the interior water of water tank can not flow out easily;
During exhaust condition, as shown in Figure 2, at this moment, rotation Exhaust screw 1 makes it to move down, and promotion suction valve 6 moves down, make the lower end surface of suction valve 6 break away from lower seal rubber cushion 11, water tank inner high voltage gas, boiled water be able to along through hole on the lower seal skeleton 10, on the vent 3 and the overflow hole on the tank filler opening 54 that seal on the skeleton 13 discharge, guaranteed when fetching boiling water case lid, the case internal pressure is consistent with ambient pressure, and boiled water can splash in the water tank.
