Description
Technical field
The utility model relates to a kind of pad, particularly a kind of efficient sealed valve mechanism cover pad.
Background technique
Existing valve mechanism cover pad is located between cylinder head, valve mechanism cover, and by turning valve mechanism cover nut, make valve mechanism cover nut be pressed on seal ring, seal ring is pressed in valve mechanism cover, and valve mechanism cover is pressed on valve mechanism cover pad.Valve mechanism cover pad is the gum part that intensity is low, and when tightening valve mechanism cover nut, valve mechanism cover pad easily because intensity is low and compressibility can not get effective control and by conquassation, causes sealing easily occurring losing efficacy.
Model utility content
The purpose of this utility model is to provide one to overcome the deficiencies in the prior art, has easy to manufacture, easy to install, and pressure-resistant seal performance is good, improves the efficient sealed valve mechanism cover pad of one of " three leak " problem.
Technical solution of the present utility model is such, a kind of efficient sealed valve mechanism cover pad, comprise cylinder head, valve mechanism cover pad, valve mechanism cover, connecting screw rod, seal ring, valve mechanism cover nut, the vulcanization of rubber is pasted, it is characterized in that valve mechanism cover pad (2) is arranged between the connection part of cylinder head (1) and valve mechanism cover (3), be connected by connecting screw rod (4) between cylinder head (1) with valve mechanism cover (3) and tighten up, there is valve mechanism cover nut (6) on connecting screw rod (4) top, valve mechanism cover nut (6) card is pressed in above seal ring (5), seal ring (5) card is pressed in the installation orifice ring limit of valve mechanism cover (3), valve mechanism cover pad (2) inner ring edge is stained with the vulcanization of rubber and pastes (21), the vulcanization of rubber paste (21) and valve mechanism cover pad (2) block be pressed between cylinder head (1) to valve mechanism cover (3) interior to the inside, (21) and valve mechanism cover pad (2) consubstantiality are pasted in the vulcanization of rubber.
Connecting screw rod (4) upper and lower end has screw thread, and connecting screw rod (4) lower end screw thread and cylinder head (1) connection hole are threaded connection, and connecting screw rod (4) upper end and valve mechanism cover nut (6) are threaded connection.
Valve mechanism cover pad (2) and the vulcanization of rubber are pasted (21) and are arranged on connection choma limit between cylinder head (1) to valve mechanism cover (3).
Valve mechanism cover pad (2) is tinsel, and (21) are pasted in the vulcanization of rubber is rubber-plastics material.
Under valve mechanism cover pad (2) is contained in valve mechanism cover (3) flanged surface.
Compared with prior art, the beneficial effects of the utility model are: have the rubber of good compensation and rigidity very well but the metallic shim perfect adaptation that be short of of sealing, simply, easy to manufacture, good airproof performance, long service life, cost is low, applied range for structure.
Accompanying drawing explanation
Fig. 1 is that erection drawing installed by the pad of prior art.
Fig. 2 is installation of the present utility model assembling front sectional view.
Fig. 3 is of the present utility model by the pad installation position broken section amplification technique of painting figure in Fig. 1.
Reference character: cylinder head (1), valve mechanism cover pad (2), valve mechanism cover (3), connecting screw rod (4), seal ring (5), valve mechanism cover nut (6), the vulcanization of rubber paste (21).
Embodiment
Embodiment 1, valve mechanism cover pad (2) is located between cylinder head (1) and valve mechanism cover (3), the vulcanization of rubber pastes (21) on the inward flange of valve mechanism cover pad (2), valve mechanism cover nut (6) is made to be pressed on seal ring (5) by turning valve mechanism cover nut (6), seal ring (5) is pressed in valve mechanism cover (3), and valve mechanism cover (3) is pressed on valve mechanism cover pad (2).The composite sheet that valve mechanism cover pad (2) is metallic shim and rubber parts, when tightening valve mechanism cover nut (6), valve mechanism cover pad (2) obtains fastening, the vulcanization of rubber pastes (21) at metallic shim inward flange, because the main body of valve mechanism cover pad (2) is metallic shim, the intensity of metallic shim is high, and the area of pad is large, rigidity is stronger, the vulcanization of rubber making to be pasted onto metallic shim inward flange is pasted (21) compressibility when compressing and to be controlled and not by conquassation, the Problem of Failure that the cylinder head gasket (2) solving original gum material causes because compressibility is out of control.
Embodiment 2, with reference to embodiment 1, total composition is constant, installation relation is constant, but cylinder head sheets (2) is pasted (21) with the vulcanization of rubber be separated, respectively have a style of one's own, namely valve mechanism cover pad (2) is metallic shim, (21) are pasted in the vulcanization of rubber is rubber material, and/or plastic material, during installation first the vulcanization of rubber paste (21) card be pressed in cylinder head (1) and valve mechanism cover (3) inner between, then the vulcanization of rubber be pressed between cylinder head (1) and valve mechanism cover (3) of valve mechanism cover (3) card is pasted the outward edge of (21) afterwards again.
Embodiment 3, and with reference to embodiment 1,2, overall structure composition is constant with the relation of installation, but valve mechanism cover pad (2) card is pressed in the outward edge of cylinder head (1) to valve mechanism cover (3).
