Usual operating ambient temperature range is -40 DEG C ~ 110 DEG C, and as system cooling medium changes in temperature, system coolant liquid is held
Product changes therewith, and the purpose of the observation window of liquid level is exactly to facilitate locomotive work person in use can very intuitive judgment
Whether system liquid level is in normal range.The use temperature range of observation window of liquid level is wide, and sealing material wants resistance to cooling medium
Corrosion, resistance to low cold, high temperature aging again, simultaneously because vibratory impulse is to life of product and leakproofness in vehicle operation
Can influence, therefore designing the strong observation window of liquid level of a kind of high reliablity, corrosion resistance is a core for improving system reliability
Heart project.Existing observation window of liquid level has the following deficiencies: on the one hand, observation glass tube is not easy to install, in an assembling process easily
Rupture, scrappage are high；On the other hand, in the case where long-time vibrates working environment, sealing element, which is easy breakage, leads to that there are liquid leakages
Failure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of liquid level observation dress for prior art deficiency and defect
It sets.
To achieve the above object, the utility model uses following technical scheme:
A kind of observation window of liquid level device, including expansion tank and observation window of liquid level body.
Observation window of liquid level body includes glass tube, mounting base, and the mounting base includes upper mounting seat and lower mounting seat, glass tube
Between upper mounting seat and lower mounting seat, mounting base is equipped with groove compatible with glass tube upper and lower ends, sets in groove
There is ring type seal, glass tube both ends are securable in ring type seal, and upper mounting seat is equipped with lower mounting seat and glass tube
The first through hole of inner cavity connection.
Expansion tank panel side and upper mounting seat and lower mounting seat are equipped with connection through-hole, and movable bolt passes through connection through-hole
Observation window of liquid level body is fixed on expansion tank side.
It is equipped with the second through-hole inside the movable bolt, first through hole and the second through-hole and glass can be passed through inside expansion tank
The connection of glass tube cavity.
Further, ring type seal inner and outer ring is equipped with annular protrusion not of uniform size, which can increase
Strong leakproofness, while in glass tube and sealing ring extrusion process, which can store extruding air and make glass tube, sealing
There are certain air cushions between circle, mounting base, do not easily cause the damage failure of sealing element and glass tube.
Further, the mounting base abutting expansion tank side and abutting bolt head side are equipped with O-ring seal, adopt
The leakproofness of mounting base and expansion tank, bolt is improved with dual face seals structure, and sealing ring and liquid are completely isolated, it is ensured that close
Seal extends seal life from the corrosiveness of liquid.
Further, the observation window of liquid level body further includes aluminum alloy material outer cover, and outer cover setting is corresponding with glass tube
Transparent sight hole indicates cubical content scale on observation window and conveniently checks.
The beneficial effects of the utility model are that the observation window of liquid level device is easily installed and scrappage is low, and leakproofness is stronger:
The ring type seal that the observation window of liquid level of the utility model is placed in mounting base groove compatible with glass tube upper and lower ends
There is annular protrusion not of uniform size, the installation of glass tube both ends is fixed into after mounting base, outside annular protrusion structure on inner and outer ring
Ring surrounds mounting base groove, inner ring surrounds glass tube both ends, squeezes air and is stored between protrusion and sealing surface, so that sealing
Retain certain air cushion between part and sealing surface, so that not easily causing sealing element to damage when vibration；Simultaneously mounting base with it is swollen
Swell, bolt head coupling part are respectively provided with O-ring seal, and used dual face seals structure greatly improves sealing performance, in addition O
Property sealing ring and cooling medium it is completely isolated from liquid corrosion prolonged action seal life reduce failure；Aluminium alloy outer cover changes
With aluminum alloy material, the weight that liquid level observes device is also greatly alleviated compared to previous general stainless steel material.
