Description
Technical field
The utility model relates to the heat convection type radiator of single cylinder diesel, relates in particular to a kind of pressure equaliser with radiator of low evaporation effect.
Background technique
The single cylinder diesel great majority adopt evaporation-type heat radiator, because the open type design is adopted in buoy and filler, lumen of radiator pressure and external pressure are equivalent, when such single cylinder diesel moves to declared working condition or moment of torsion operating mode, diesel engine gives out a large amount of heats, after the cooling water vaporization directly from the filler ascension to atmosphere, at this moment the water vapour evaporation rate is very fast, words such as untimely interpolation water, can carry out dry combustion method and damage airframe components body, thus, then directly caused the water usage of diesel engine to increase, in the usual operating time, the number of water of diesel engine was limited at and need adds water one time every about two hour, when using diesel engine in the place of the northern area of drought and water shortage and mountain area or few aqua region, can be subject to larger constraints limit.
Summary of the invention
The utility model provides a kind of pressure equaliser of heat convection type radiator, its purpose is to guarantee lumen of radiator hot steam constant pressure, effectively prevent the too fast evaporation of water vapour, reduce people and add frequently cooling water, and can realize the effect of saving water resource.
The utility model comprises upper valve body and lower valve body, described upper valve body is by the first rivet one loam cake, be provided with the spring for the loam cake movable reset between described upper valve body and the loam cake, the inner of described loam cake stamps out the holding cavity of installing for lower valve body, one second rivet is installed on the described lower valve body, one end of described the second rivet is riveted a little valve, is provided with little spring between the end limit of described the second rivet and lower valve body.
Cover on described and be provided with the loam cake exhaust port.
The position, joint of described loam cake and lower valve body is provided with seal ring.
Be provided with a spring sheet between described upper valve body and the spring.
Described lower valve body is provided with lower exhaust port.
Be provided with rubber pad between described lower valve body and the little valve.
The week of described upper valve body is along a buckle ear is set with locating horizontal symmetrical.
The beneficial effects of the utility model are: be provided with the spring for the loam cake movable reset between upper valve body and the loam cake, the inner of described loam cake stamps out the holding cavity of installing for lower valve body, one second rivet is installed on the described lower valve body, one end of described the second rivet is riveted a little valve, be provided with little spring between the one end limit of described the second rivet and lower valve body, pressure texture by loam cake can guarantee effectively that diesel engine in normal operation, lumen of radiator hot steam constant pressure, and be higher than the external pressure certain value, can effectively keep the water vapour water droplet, reduce the water usage of radiator, the cooling-down effect that helps continuous firing, make the pressure in the radiator remain on certain limit by upper valve body and lower valve body simultaneously, guarantee that radiator can not destroyed because pressure difference is excessive, be adapted at the use of lack of water zone or popularization on a large scale.

Embodiment
With reference to the accompanying drawings the utility model is described in detail, as shown in Figure 1, the utility model comprises upper valve body 1 and lower valve body 2, described upper valve body 1 is by the first rivet 11 riveted joints one loam cake 12, be provided with the spring 13 for loam cake 12 movable resets between described upper valve body 1 and the loam cake 12, the inner of described loam cake 12 stamps out the holding cavity 14 of installing for lower valve body 2, one second rivet 21 is installed on the described lower valve body 2, one end of described the second rivet 21 is riveted a little valve 3, be provided with little spring 22 between the one end limit of described the second rivet 21 and lower valve body 2, for convenient ventilative, described loam cake 12 is provided with loam cake exhaust port 121, described lower valve body 2 is provided with lower exhaust port 23, and can fasten between the utility model and the radiator in order to make, the week of described upper valve body 1 is along a buckle ear 16(being set with locating horizontal symmetrical as shown in Figure 2), simultaneously, increase the sealing effect of upper valve body 1, be provided with a spring sheet 15 between upper valve body 1 and the spring 13, for guarantee and radiator between good sealing effect is arranged, described loam cake 12 is provided with seal ring 122 with the position, joint of lower valve body 2, in addition, be provided with rubber pad 24 between described lower valve body 2 and the little valve 3, rubber pad 24 is the usefulness for the lower exhaust port 23 of the lower valve body 2 of sealing.
Concrete principle of the present utility model is such as figure, when diesel engine is in idling or small load condition, cooling water vapor volume in the radiator A is few, pressure in the radiator A is not high, be in the spring 13 past loam cakes 12 that pressing down under the compressive state, meanwhile, be in the little spring 22 little valve 3 of jack-up up under the compressive state, so that the loam cake 12 that radiator A covers and lower valve body all are in closed condition, pressure in the radiator A is higher than the ambient atmosphere certain value and keeps constant, water vapour remains in the radiator A, by described seal ring 122 and rubber pad 24 sealings.
As shown in Figure 3, when diesel engine continuously in demarcation situation or overload operating mode when work, cooling water temperature raises in the radiator A, steam vapour amount increases, the internal pressure of radiator A is raise, when pressure reaches critical setting value, loam cake 12 is in the jack-up situation for the treatment of, along with pressure continues to raise, loam cake 12 is by jack-up, and the steam of High Temperature High Pressure is then discharged along the mouth place, edge of radiator A, and then from tracheae B toward extraneous discharging, effectively prevented the spalling in the radiator A, the water droplet that the water vapour of this moment is met cold one-tenth water still is retained in the upper valve body 1, realizes reclaiming again.When pressure returned in the specified value again, loam cake 12 resetted under the elastic force effect of spring 13 and closes.
As shown in Figure 4, after diesel engine quit work, the water convection current in the drop in temperature, radiator A slowed down, volume-diminished, and at this moment the pressure in the radiator A begins to descend.When pressure during less than specified value, because degree of vacuum attracts so that little valve 3 drives rubber pads 24 down opens, at this moment, outside air just enters by tracheae B, flow through the loam cake exhaust port 121 of loam cake 12 and the lower exhaust port 23 of lower valve body 2, enter again and fill air pressure in the radiator A, prevent that radiator A from being damaged by pressure by atmospheric pressure, when the pressure in the radiator returns near atmospheric pressure, little valve 3 is under little spring 22 effects, the lower exhaust port 23 that drives 24 pairs of lower valve bodies 2 of rubber pad is closed, and makes once again radiator and system thereof form a seal space.
