Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can be mutual
Combination.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with in this utility model embodiment
Accompanying drawing, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment
It is only the embodiment of this utility model part rather than whole embodiments.Based on the embodiment in this utility model, this
The every other embodiment that field those of ordinary skill is obtained under not making creative work premise, all should belong to this reality
By novel protected scope.
According to the expansion tank of this utility model embodiment, as depicted in figs. 1 and 2, including: casing 10 and regulator 20,
Casing 10 has water inlet and discharge outlet；Regulator 20 is arranged on casing 10, for according to the pressure within casing 10
Change by pressure regulation casing 10 within preset range.
Application technical solutions of the utility model expansion tank, by have on water inlet and discharge outlet casing 10 arrange pressure regulation fill
Putting 20, the pressure within casing 10 can be regulated to preset range by regulator 20 according to the change of casing 10 internal pressure,
Thus continue to supplement water to diesel engine cooling system with stable pressure.Solve the water of diesel engine cooling system of the prior art
The technical problem that in case, hydraulic pressure is unstable.
When being embodied as, regulator 20 includes: pressure regulator valve, and pressure regulator valve can change pressure according to the pressure within casing 10
Power carries out real-time regulation, and casing 10 is seal case, and when casing 10 is intake, pressure increases, and during casing 10 draining, pressure reduces,
When the pressure in casing 10 is more than the first preset pressure, pressure regulator valve can automatically open up a certain amount of air of discharge, makes pressure reduce
To the scope less than the first preset pressure, when the pressure in casing 10 is less than the second preset pressure, pressure regulator valve can be automatically switched off,
Along with water pump supplies water in casing 10, the pressure in casing 10 can gradually rise in the range of more than the second preset pressure；Its
In, the first preset pressure is more than the second preset pressure, by the real-time regulation of pressure regulator valve, makes the pressure in casing 10 be in all the time
More than the second preset pressure and less than in the range of the first preset pressure, it is ensured that the stablizing of pressure in casing 10, thus ensure with surely
Fixed pressure continues to supplement water to diesel engine cooling system.It addition, when water pump breaks down, it is also possible to manual by regulation valve
A small amount of water is supplemented, to tackle case of emergency to expansion tank.
In order to the height of water level observed timely in expansion tank, as depicted in figs. 1 and 2, casing 10 also sets up
Water level indicating device 30, water level indicating device 30 is had to include a transparent tube 31, the lower end of transparent tube 31 and casing 10 times
Portion connects, and the upper end of transparent tube 31 connects with the top of casing 10, thus can be visually observed that expansion by transparent tube 31
Height of water level in water tank.
Transparent tube 31 in use between can retain a large amount of incrustation scale on inwall long afterwards, thus the observation that impact is to water level, for the ease of
Change transparent tube 31, as in figure 2 it is shown, be provided with the first valve 32 in the bottom of casing 10, be provided with on the top of casing 10
Second valve 33, the lower end of transparent tube 31 is connected with casing 10 by the first valve 32, and the upper end of transparent tube 31 passes through second
Valve 33 connects with casing 10, when transparent tube 31 changed by needs, the first valve 32 and the second valve 33 is turned off, from
And prevent the water in expansion tank from spraying under pressure, after transparent tube 31 is changed, then by the first valve 32 and second
Valve 33 is opened.
In some cases, the water pump of diesel engine there will be fault, it is impossible to expansion tank moisturizing, and in manual observation expansion tank
Water level there will be again the situation of carelessness, in order to prevent occurring that carelessness causes the water level in casing 10 too low by manual observation water level
Thus impact is supplied water to cooling system, and then diesel engine outlet high temperature is caused to cause the accident.As depicted in figs. 1 and 2, at casing
It is additionally provided with water level alarm 40 on 10, water level alarm 40 can set the minimum of the water level that expansion tank normally works
Value, when the water level of casing 10 is less than this minimum, water level alarm 40 is reported to the police, and reminds staff's water pump that event occurs
Barrier, thus quickly process.
Expansion tank is bearing device, in use between after long afterwards, casing 10 is internal likely there will be situation about snapping, and causes
Send leakage accident, in order to be easy to staff to check the situation of casing 10, as depicted in figs. 1 and 2, at casing 10
Be arranged above check hole 50, check there is port lid 51 on hole 50, port lid 51 is detachably connected to inspection by bolt
Being sealed in inspection hole 50 on hole 50, under needs check casing 10 inner case, taking off port lid 51 can check.
Owing to casing 10 length is longer, checking that hole 50 is provided with two, two check that hole 50 is separately positioned on regulator 20
Both sides such that it is able to thus different azimuth and angle check that casing 10 is internal whether has the situation of snapping.Ensure the complete of examination scope
Cover.
For convenience expansion tank is fixed, as it is shown in figure 1, be additionally provided with fixed mount 60 on expansion tank, fixed mount 60
Being connected with casing 10, casing 10 is fixed on installation foundation by fixed mount 60.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this area
For technical staff, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, institute
Any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
