Description
Technical field
The utility model relates to the improvement invention in automobile component field, particularly relates to a kind of improvement invention of enclosed swelling water tank assembly.
Background technique
Engine for automobile cooling swelling water tank is the device of water in a kind of automatic vehicles engine water tank.During motor car engine work, what enter swelling water tank from motor and intercooler gas removing pipe is the steam water interface of High Temperature High Pressure, and it cool also after bubble in swelling water tank, enters engine water tank recycle through backwater mouth.For ensureing cooling effect, remain a certain amount of cooling liquid swelling water tank planted agent, to ensure that engine cooling is lowered the temperature, the needs of safe operation.And the pressure cover on swelling water tank casing, its opened by pressure value is fixed, and cannot adapt to the requirement of different water tank to positive pressure pressure unlatching value.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides the enclosed swelling water tank assembly that a kind of pressure cover opened by pressure value is adjustable.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind of enclosed swelling water tank assembly, include water tank assembly, add water cover and pressure cover, it is characterized in that: described pressure cover includes pressure cover shell, is fixed on the pressure valve casing in pressure cover shell and is arranged on pressure valve seat, pressure spring, vacuum valve seat, seal spool pad, pallet and the vacuum spring in pressure valve casing; Described pressure valve seat is fixed in pressure valve casing, described pressure spring is arranged in the cavity on pressure valve seat, and pressure spring one end is connected to bottom pressure valve seat cavity, the other end connects the pallet being arranged on pressure valve seat top, with the surface of contact height adjustable of pressure spring bottom described pressure valve seat cavity; Described seal spool pad is arranged on pallet, and described vacuum valve seat is through seal spool pad and pallet and be connected with the two; Described vacuum spring is arranged in the cavity on vacuum valve seat, and vacuum spring one end connects vacuum valve seat cavity, the other end Bonding pressure valve casing.
Bottom described pressure valve seat cavity and be provided with the removable shim regulating surface of contact height between pressure spring.
The side-wall outer side of described pressure valve casing is provided with annular groove, is provided with seal washer in groove.
The described water cover that adds, for screwing lid, is provided with gasket seal inside the lid top wall that adds water, and adds water cover port and is provided with seal washer.
The beneficial effects of the utility model are the enclosed swelling water tank assemblies after improving, by regulating the height of pressure valve seat inside and pressure spring surface of contact, namely by setting up removable shim, thus change the reduction stroke of pressure spring, adapt to the requirement of different tank lid to positive pressure pressure unlatching value; Decrease the quantity of mould development simultaneously, ensure mutually using of inner body, reduce the construction cycle, Improve Efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.See accompanying drawing 1, this enclosed swelling water tank assembly, include water tank assembly, add water cover and pressure cover, water tank assembly is provided with main chamber and secondary chamber, water tank assembly is provided with disappointing interface and water injection interface, and pressure cover includes pressure cover shell 1, is fixed on the pressure valve casing 2 in pressure cover shell 1 and is arranged on pressure valve seat 3, pressure spring 4, vacuum valve seat 5, seal spool pad 6, pallet 7 and the vacuum spring 8 in pressure valve casing 2; Described pressure valve seat 3 is fixed in pressure valve casing 2, described pressure spring 4 is arranged in the cavity on pressure valve seat 3, and pressure spring 4 one end is connected to bottom pressure valve seat 3 cavity, the other end connects the pallet 7 being arranged on pressure valve seat 3 top, with the surface of contact height adjustable of pressure spring 4 bottom described pressure valve seat 3 cavity, preferably set up removable shim between, whether pad uses and spacer thickness can need to select according to pressure; Described seal spool pad 6 is arranged on pallet 7, described vacuum valve seat 5 is through seal spool pad 6 and pallet 7 and be connected with the two, the shoulder rank of vacuum valve seat 5 are butted on seal spool pad 6, and vacuum valve seat 5 can drive seal spool pad 6 and pallet 7 to move axially; Described vacuum spring 8 is arranged in the cavity on vacuum valve seat 5, and vacuum spring 8 one end connects vacuum valve seat 5 cavity, the other end Bonding pressure valve casing 2.
The side-wall outer side of described pressure valve casing 2 is provided with annular groove, is provided with seal washer 9 in groove, enhances the sealing of pressure valve casing 2.The described water cover that adds, for screwing lid, is provided with gasket seal inside the lid top wall that adds water, and adds water cover port and is provided with seal washer, double sealing structure, enhance the sealing adding water cover.
Water tank assembly of the present utility model is divided into main chamber and two, secondary chamber part, and main chamber is built with a certain amount of cooling liquid, and pressure cover is communicated with main chamber and secondary chamber.Make pressure in cavity increase when the steam water interface of High Temperature High Pressure enters in main chamber, when pressure is greater than setting pressure, vacuum spring 8 in pressure cover will be compressed, vacuum valve seat 5 drives seal spool pad 6 to move under the pressure effect of vacuum spring 8, now, produce gap between pressure valve casing 2 and pressure valve core gasket seal 6, the steam water interface with cooling liquid will flow through gap, flow in secondary chamber, will the recovery of cooling liquid be completed.When after high temperature and high pressure gas cooling, in main chamber, pressure reduces, when in main chamber, pressure is lower than secondary chamber, pressure spring 4 will be compressed, pallet 7, at the move under influence of pressure spring 4, produces gap between pressure valve casing 2 and seal spool pad 6, and cooling liquid will be got back to main chamber along original route and again be utilized.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
