Embodiment
As shown in Figure 2 and Figure 3, the present embodiment is a kind of diesel fork lift truck degassing type swelling water tank, comprising cross section is trapezoidal swelling water tank body 2, this swelling water tank body be arranged on by water tank bearing 8 protect solar or lunar halo 1 inclined-plane on (fitting with the inclined-plane protecting solar or lunar halo 1 in swelling water tank body 2 inclined-plane), conserve space, make layout in fork truck hood compacter, clean and tidy, be convenient to observe.In this example, swelling water tank body 2 adopts aluminium plate to be welded, and makes all to be better than transparent plastics secondary cistern in its intensity and working life.Liquid level display device 4 is equipped with in swelling water tank body 2 front end, and liquid level display device inside communicates with swelling water tank, thus clearly can find out the position of cooling-liquid level in swelling water tank body in outside.Swelling water tank body is also housed built with level sensor 5 in swelling water tank body 2, water level sensor circuit connection control device and alarm, when water level is lower than desired location, controller receives level sensor signal, controls alarm equipment alarm.The present embodiment has machinery and electronics two kinds of liquid level mode of observations, not only improves level sensing efficiency, and effectively avoids the too low accident caused of cooling-liquid level.Water injecting pipe 7 is provided with, connecting engine and swelling water tank body 2, for the filling of cooling liquid in cooling system and the water circulation of cooling system on the downside of swelling water tank body 2.
Be welded with a filler pipe 9 in swelling water tank body 2 upper end in the present embodiment, this filler pipe lower portion is in swelling water tank body, and the first half is exposed to swelling water tank, and this is external.In filler pipe 9 upper end, tube wall is shaped with steam outlet pipe 92, filler pipe upper end setting pressure lid 3, and pressure cover inside has a pressure valve 31 and a vacuum valve 32, and pressure valve is communicated with in filler pipe 9 with vacuum valve and steam outlet pipe 92 communicates.
As shown in Figure 4, in the present embodiment, pressure cover 3 comprises pressure valve 31, vacuum valve 32, lid 33 and sealed cover 34, and sealed cover 34 is placed in lid 33, and pressure valve 31 and vacuum valve 32 are installed on below sealed cover.When sealed cover spiral-lock is in filler pipe 9 upper-end surface, pressure valve 31 and vacuum valve 32 are positioned at filler pipe 9.
In this example, pressure valve 31 comprises fixed bolt I 311, pressure valve valve body 312, pressure valve spring 313 and sealing rubber ring I 314.Lid 33 and sealed cover 34 are fixed on fixed bolt I 311 upper end, and fixed bolt I bottom is moving up and down is set with pressure valve valve body 312, and this valve body is inverted bowl-shaped shell, and center, bowl bottom position has the circular hole coordinated with fixed bolt I 311.The rim of a bowl edge of pressure valve valve body 312 lower end is provided with sealing rubber ring I 314, and sealing rubber ring I is supported in below steam outlet pipe 92, on the step of filler pipe 9 inwall, and sealing rubber ring I 314 can coordinate with step in filler pipe 9 and realizes sealing.In this example, pressure valve spring 313 is placed on outside pressure valve valve body 312, and this both ends of the spring is connected with pressure valve valve body 312 with sealed cover 34 respectively.
In this example, vacuum valve 32 comprises fixed bolt II 321, vacuum valve valve body 322, vacuum valve spring 323 and sealing rubber ring II 324, and wherein vacuum valve valve body 322 is bowl-shaped shell, and setting-in to be fixed in pressure valve valve body 312 and to surround closed cavity with pressure valve valve body.In this example, fixed bolt II 321 is through vacuum valve valve body 322 Wan Di center (it is inside and outside that this fixed bolt II upper and lower end lays respectively at closed cavity), and fixed bolt II can move up and down by relative vacuum valve body.Vacuum valve spring 323 is placed on the fixed bolt II in closed cavity, and both ends of the spring connects vacuum valve valve body and fixed bolt II upper end respectively.Have the through hole II 325 of some connection closed cavities at the bottom of vacuum valve valve body 322 bowls, vacuum valve valve body lower portion is equipped with the sealing rubber ring II 324 for shutoff through hole II, and sealing rubber ring II is connected and fixed bolt II lower end through connecting plate 326.The through hole I 315 of some connection closed cavities is had at the bottom of pressure valve valve body 312 bowls.In the present embodiment, pressure valve 31 is integrated with vacuum valve 32, and structure is simple, safe and reliable.
Sealing rubber ring I 314 is fastened by pressure valve valve body 312 the rim of a bowl edge and vacuum valve valve body 322 the rim of a bowl edge card.
When in swelling water tank body 2 during cooling liquid expanded by heating, the pressure of the intrinsic gas of swelling water tank is opened (as Fig. 5 more than pressure valve during 1.0 ~ 1.1bar 31, above pressure valve valve body 312, pressure is less than below pressure, pressurized moves up, pressure valve spring 313 compresses), air discharges, and prevents the too high swollen bad core pipe of water tank internal pressure; When coolant temperature in swelling water tank body reduces, when the gas negative pressure power of swelling water tank body is low to moderate 0 ~ 7kPa, vacuum valve opens that (above envelope rubber ring II 324, pressure is greater than below pressure, envelope rubber ring II 324 pressurized moves down, drive connecting plate 326 and fixed bolt II downward, vacuum valve spring 323 compresses), air enters swelling water tank body from the outside, prevents the low core pipe of water tank internal pressure from being damaged by pressure by atmospheric pressure.
Filler pipe 9 tube wall being positioned at swelling water tank body 2 inside offers the through hole 901 of a diameter ￠ 3, the through hole 901 in filler pipe 9 and formation expansion space, filler pipe lower end.When cooling liquid expanded by heating, liquid level rises, and the air in expansion space can be discharged by the through hole in filler pipe 9, and cooling liquid can not leak, and such cooling liquid for a long time, often can need not add cooling liquid, has saved user cost.
In the present embodiment, diesel fork lift truck degassing type swelling water tank also has the function for cooling system degasification, three elimination tracheaes 6 are equipped with in swelling water tank body 2 front end, three one end of eradicating tracheae are connected in the highest point of motor and radiator coolant circulation, and the other end is connected to the expansion space of degassing type swelling water tank.When the water pump of motor promotes liquid circulation, the air in cooling system is brought into expansion space by gas removing pipe 6, thus realize cooling system degasification.
