Abstract
The utility model discloses a pressure cover for an expansion water box of a heavy truck, comprising a pressure cover shell (6), a pressure valve shell (4) fixed on the pressure cover shell (6), an internal sealing washer (1) fixed on the pressure valve shell (4), an external sealing ring (5) fixed on the pressure cover shell (6), a pressure valve seat (8) arranged in the pressure valve shell (4), a pressure spring (7), a vacuum valve seat (10), a valve core sealing washer (2), a valve cover sealing washer tray (3) and a vacuum spring (9). The pressure cover for the expansion water box of the heavy truck is communicated with a main chamber and an auxiliary chamber of the box body. By modifying the structure, the pressure cover for the expansion water box has two sealing surfaces, and when the pressure intensity in the chamber body is more than the arranged pressure intensity, the vacuum spring (9) in the pressure cover is compressed and drives the valve core sealing washer (2) to motion, so that the clearance exists between the pressure valve shell (4) and the valve core sealing washer (2), and the cooling liquid can be reclaimed when flowing through the clearance. The pressure cover has a simple structure and can be applied conveniently.
Description
Technical field
The utility model relates to the automobile component field, relates to a kind of motor car engine cooling and uses the swelling water tank pressure cover, is specifically related to a kind of heavy duty truck engine cooling swelling water tank pressure cover.
Background technique
Engine for automobile cooling swelling water tank is the device of water in a kind of automatic adjusting radiator of car engine.In motor car engine when work,, what enter swelling water tank from motor and intercooler gas removing pipe is the steam water interface of High Temperature High Pressure, after it cools off in swelling water tank and separates out bubble, enters engine water tank through backwater mouth and recycles.For guaranteeing cooling effect, remain a certain amount of cooling liquid the swelling water tank planted agent, to guarantee engine cooling cooling, the needs of safe operation.The swelling water tank pressure cover is arranged on the swelling water tank casing.Existing heavy card swelling water tank pressure cover, following deficiency is arranged: when swelling water tank casing internal pressure during greater than the pressure cover cracking pressure, pressure cover will be opened automatically, and the steam water interface that contains cooling liquid can partly enter atmosphere, to produce 3 harm: the first, befouling environment; The second, cause the cooling liquid waste; The 3rd, drop drips on the vehicle body after the condensation, and the corrosion auto parts produce potential potential safety hazard.
The model utility content
The purpose of this utility model is to provide a kind of heavy card swelling water tank pressure cover, and when solving pressure cover and opening automatically, the steam water interface that contains cooling liquid partly enters atmosphere and the problem that causes.
To achieve these goals, the technical solution adopted in the utility model is:
Described this heavy card swelling water tank pressure cover comprises interior seal washer, seal spool pad, seal spool pad pallet, pressure valve casing, exterior seal ring, pressure cover shell, pressure spring, pressure valve seat, vacuum spring, vacuum valve seat.
Described pressure valve casing is fixed on the pressure cover shell.As further improvement of the utility model, described pressure valve casing is installed on the pressure cover shell.Seal washer is fixed on the pressure valve casing in described, and described exterior seal ring is fixed on the pressure cover shell.
As further improvement of the utility model, described interior seal washer is sleeved on the pressure valve casing, and described exterior seal ring is sleeved on the pressure cover shell.
Seal washer and exterior seal ring play seal action to pressure valve casing and pressure cover shell in described, thereby form two sealing surfaces.Described pressure valve seat, pressure spring, vacuum valve seat, seal spool pad, seal spool pad pallet, vacuum spring all are arranged in the pressure valve casing.
Described pressure valve seat is fixed on the pressure valve casing, and described pressure spring one end is stuck on the pressure valve seat.
As further improvement of the utility model, described pressure valve seat is installed on the pressure valve casing.
Described vacuum spring one end is fixed on the vacuum valve seat, and vacuum valve seat passes seal spool pad and seal spool pad pallet and is fixed together with the two.The described pressure spring the other end is installed on the seal spool pad pallet.
Described heavy card is contained in the swelling water tank pressure cover on the casing of swelling water tank, and casing is divided into two parts in main chamber and secondary chamber, and a certain amount of cooling liquid is housed in the main chamber, and pressure cover is communicated with main chamber and secondary chamber.When the steam water interface of High Temperature High Pressure enters in the main chamber, make and press in the cavity chamber to increase, when pressure when setting pressure, described heavy card will be compressed with the vacuum spring in the swelling water tank pressure cover, vacuum valve seat drives the motion of seal spool pad under the pressure effect of vacuum spring, at this moment, produce the gap between pressure valve casing and pressure valve core gasket seal, the steam water interface that has cooling liquid will flow through the gap, flow in the secondary chamber, will finish the recovery of cooling liquid.
After the high temperature and high pressure gas cooling, pressure reduces in the main chamber, when pressure is lower than secondary chamber in the main chamber, pressure spring will be compressed, seal spool pad pallet moves under the effect of pressure spring, produce the gap between pressure valve casing and seal spool pad, cooling liquid will be got back to main chamber along original route and be utilized once more.
Advantage of the present utility model is: by the improvement of counterweight card with swelling water tank pressure cover structure, make the swelling water tank pressure cover have two sealing surfaces, when entering, the steam water interface of High Temperature High Pressure make in the cavity pressure when setting pressure in the main chamber, vacuum spring in the pressure cover will be compressed, drive the motion of seal spool pad, make to produce the gap between pressure valve casing and seal spool pad that cooling liquid flows through the gap, flow in the secondary chamber, cooling liquid obtains reclaiming.When pressure was lower than secondary chamber in the main chamber, pressure spring fell and is compressed, and seal spool pad tray motion produces the gap between pressure valve casing and seal spool pad, and cooling liquid will be got back to main chamber along original route and be utilized once more.The utility model is simple in structure, and it is convenient to use.
