Abstract
An all-aluminium multi-seal valve comprises an upper shell and a lower shell. The upper shell and an upper air bleed valve are cast together via an all-aluminium casting mode, and the lower shell and a lower connecting piece are cast together via the all-aluminium casting mode. The all-aluminium multi-seal valve is characterized in that an edge portion is arranged on the inner side of the lower portion of the upper shell, and the edge portion and the upper shell are of an integral cast structure. A trapezoid-shaped slot is formed in the inner side of the upper portion of the lower shell, and a round sealing ring is mounted on the outer side of the edge portion and embedded in the trapezoid-shaped slot along with the edge portion. Since the round sealing ring is arranged between the edge portion and the trapezoid-shaped slot, gas leakage is prevented, and sealing effect is improved. The all-aluminium multi-seal valve is simple in structure and reasonable in design, the upper shell and the lower shell are assembled quite conveniently, and qualified rate of products is increased.
Description
Technical field
The utility model relates to a kind of complete many seal valves of aluminium, belongs to the technical field of heating system automatic control pressure vent door device aspect.
Background technique
At present, known outlet valve is provided with sealing gasket at the joint of upper shell and lower shell body, is used for playing seal action.As multinomial model utility and the patent of invention of the applicant application, all disclose in the groove of the joint of upper shell and lower shell body and be provided with sealing gasket.This joint at upper shell and lower shell body is all provided with groove, the drawback that is provided with the way of sealing gasket in its groove is: because of sealing gasket little, compare also flexible not with steel wire sealing gasket, if its sealing gasket not circle is careless slightly in the time that the joint of upper shell and lower shell body is placed sealing gasket, its sealing gasket is bad to be placed in its groove, once its sealing gasket is just being put not, between upper shell and lower shell body, will leak gas, cause product defective, re-assemblying to delay work mistakes, and sometimes also can cause the waste of sealing gasket.
Model utility content
The deficiency existing for above-mentioned technical problem, the utility model object is to provide a kind of complete many seal valves of aluminium.
The technical solution of the utility model is as follows:
A kind of complete many seal valves of aluminium, comprise, together with its upper shell (1) is cast in by the mode of full aluminum casting with upper exhaust nozzle body, together with its lower shell body (2) is cast in by the mode of full aluminum casting with lower link, it is characterized in that: be provided with along portion (3) in upper shell (1) lower inside, described is integral type cast structure along portion (3) with upper shell (1).Inner side on lower shell body (2) top is provided with a dovetail groove (4), and circular seal ring (5) is arranged on along the outside of portion (3), with being embedded in dovetail groove (4) along portion (3).Also be to say: between portion (3) and dovetail groove (4), be provided with circular seal ring (5), thereby preventing the generation of gas leak phenomenon, improving sealing effect.
Also can make: be provided with along portion (3) in lower shell body (2) upper inner, described is integral type cast structure along portion (3) with lower shell body (2).Inner side in upper shell (1) bottom is provided with a dovetail groove (4), and circular seal ring (5) is arranged on along the outside of portion (3), with being embedded in dovetail groove (4) along portion (3).
The utility model has simple in structure, reasonable in design, very convenient in the time that upper shell (1) is assembled with lower shell body (2), has improved the up-to-standard rate of product.
Brief description of the drawings
Fig. 1 is decomposition texture schematic diagram of the present utility model.
In figure: upper shell 1, lower shell body 2, along portion 3, dovetail groove 4, seal ring 5.
Embodiment
As shown in Figure 1, a kind of many seal valves of full aluminium, comprise, together with its upper shell 1 is cast in by the mode of full aluminum casting with upper exhaust nozzle body, together with its lower shell body 2 is cast in by the mode of full aluminum casting with lower link, it is characterized in that: be provided with along portion 3 in upper shell 1 lower inside, described is integral type cast structure along portion 3 with upper shell 1.Be provided with a dovetail groove 4 in the inner side on lower shell body 2 tops, circular seal ring 5 is arranged on along the outside of portion 3, with being embedded in dovetail groove 4 along portion 3.Also be to say: between portion 3 and dovetail groove 4, be provided with circular seal ring 5, thereby preventing the generation of gas leak phenomenon, improving sealing effect.
