Description

A kind of split type SAE flanges with good seal performance
Technical field
SAE flange technical fields are the utility model is related to, are specifically related to a kind of split type with good seal performance SAE flanges.
Background technology
Flange is the part being connected with each other between pipe and pipe, for the connection between pipe end;Also have used in equipment into Flange in outlet, for the connection between two equipment, such as gear reducer flange, existing flange is often carried out using sealing ring Sealing, but as long-time uses, after sealing ring is damaged, the sealing performance of flange will substantially reduce, so as to make Into unnecessary loss, so designing a kind of split type SAE with good seal performance to increase the practical performance of flange Flange is just particularly important.
The content of the invention
The utility model is played increase practical performance and is subtracted by the sealing performance for setting two layers of sealing ring to improve The effect of few unnecessary loss;A kind of split type SAE flanges with good seal performance are provided.
To solve above-mentioned technical problem, the utility model provides a kind of split type SAE with good seal performance Flange, including
First flange, is provided with the first connecting tube in the first flange, first connecting tube removably connects It is connected in first flange,
Second flange, the second flange are connected through a screw thread component and are connected with first flange, the second flange The second connecting tube is inside provided with, second connecting tube is detachably connected in second flange,
First sealing ring, first sealing ring 3 are arranged between the first connecting tube 3 and the second connecting tube 4,
Seal sleeve, the seal sleeve are sleeved on the outside of first flange and second flange, the seal sleeve It is vertically connected with and is formed by upper bush and lower sleeve again, the upper bush and lower sleeve is all in semi-annular shape, and described is upper The second sealing ring is both provided with the madial wall of sleeve and lower sleeve,
Sleeve is protected, the protection sleeve is also in semi-annular shape, and the protection sleeve is detachably connected to set The left end of cylinder, first connecting tube is positioned at the lower section of protection sleeve.
Further:Positioning column is provided with the right side of the first flange, on the left side of the second flange Offer the location hole to match with positioning column.
Further:The left end of the upper bush offers the guide groove to match with protection sleeve right end, described The right end of protection sleeve is movably connected in the guide groove of upper bush, is set between the protection sleeve and guide groove flexible Clamping mechanism.
Further:The elastic clamping mechanism includes being opened in the groove protected on sleeve outboard sidewalls, is opened in The spherical card slot of guide groove inner wall upper half, spherical clamp and spring, the spherical clamp is by being connected in groove, the ball Shape clamp is caught in hemispherical card slot under the action of the spring.
With the above structure, the utility model is by setting two layers of sealing ring to play come the sealing performance improved Increase practical performance and reduce the effect of unnecessary loss;And the design is also high with simple in structure, easily fabricated and practicality The advantages of effect.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the enlarged drawing of A in Fig. 1.
Embodiment
A kind of split type SAE flanges with good seal performance as shown in Figure 1, including first flange 1, second flange 2nd, the first sealing ring 5, seal sleeve and protection sleeve 9, are provided with the first connecting tube 3 in the first flange 1, and described the One connecting tube 3 is detachably connected in first flange 1, and the second flange 2 is connected through a screw thread component and first flange 1 It is connected, the second connecting tube 4 is provided with the second flange 2, second connecting tube 4 is detachably connected to the second method In orchid 2, first sealing ring 5 is arranged between the first connecting tube 3 and the second connecting tube 4, seal sleeve suit In the outside of first flange 1 and second flange 2, the seal sleeve be again by upper bush 6 and lower sleeve 7 be vertically connected with group All it is in semi-annular shape into, the upper bush 6 and lower sleeve 7, is all set on the madial wall of the upper bush 6 and lower sleeve 7 There is the second sealing ring 8, the protection sleeve 9 is also in semi-annular shape, and the protection sleeve 9 is detachably connected to upper bush 6 left end, first connecting tube 3 is positioned at the lower section of protection sleeve 9.The utility model is by setting two layers of sealing ring to carry Raised sealing performance, plays the role of increasing practical performance and reduces unnecessary loss.
Positioning column 15, the left side of the second flange 2 are provided with the right side of first flange 1 as shown in Figure 1 On offer the location hole to match with positioning column 15, play the role of being easily installed by using said structure.
