Abstract
The utility model relates to a pressure cover for an expansion tank. The pressure cover for the expansion tank comprises a connecting pipe I (1) and a connecting pipe II (8). An air outlet valve seat (7) is arranged at the lower end of the connecting pipe II (8). An air outlet valve (6) is arranged on the air outlet valve seat (7). A spring II (9) is installed on the connecting pipe II (8) in a sleeved mode. A spring seat (11) is arranged at the upper end of the spring II (9). An elastic supporting part (15) is arranged at the outer end of the spring seat (11). A spring piece (13) is arranged at the top of the connecting pipe II (8). A big rubber sealing ring (12) is arranged between the spring piece (13) and the spring seat (11). A connecting gasket (14) is arranged in the center of the spring piece (13). A steel cover (10) is arranged between the connecting gasket (14) and the spring piece (13). The pressure cover for the expansion tank is capable of supporting a plastic kettle mouth of a water tank, so that the plastic is prevented from deforming in the inner side, and the condition of loosening and escaping of the water tank pressure cover is effectively reduced.
Description
Technical field
The utility model relates to a kind of swelling water tank pressure cover, belongs to technical field of automobile parts.
Background technique
The Main Function of expansion water tank for automobile is that the gas of engine-cooling system is discharged, and gives cooling add water and moisturizing, improves the pressure in cooling system, and the pressure before the raising water pump is to prevent the generation of water pump cavitation.Existing swelling water tank structure as shown in Figure 1, its tank pressure covers in the inboard not support of kettle mouth, as shown in Figure 2, therefore in use easily distortion to the inside of plastic kettle mouth after high temperature, thereby cause the outside dimension of Hu Kou to diminish, cause that the screens amount of covering with tank pressure reduces, affected the intensity of screens, easily cause the tank pressure lid to produce and get loose.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of swelling water tank pressure cover is provided, and it can support water tank plastic kettle mouth, prevents that plastics are out of shape to the inside, has effectively reduced the situation that gets loose of tank pressure lid.
the purpose of this utility model is achieved in that a kind of swelling water tank pressure cover, it comprises connecting tube I and connecting tube II, described connecting tube II lower end is provided with its gas discharge valve base, be provided with gas outlet valve on described its gas discharge valve base, be set with spring II on described connecting tube II, described spring II upper end is provided with spring seat, described spring seat outer end is provided with elastic support section, described connecting tube II top is provided with spring sheet, be provided with large rubber seal between described spring sheet and spring seat, described spring sheet center is provided with the connection packing ring, be provided with the steel lid between described connection packing ring and spring sheet.
Compared with prior art, the utlity model has following beneficial effect:
A kind of swelling water tank pressure cover of the utility model, it can support water tank plastic kettle mouth, prevents that plastics are out of shape to the inside, has effectively reduced the situation that gets loose of tank pressure lid.
