Abstract
The utility model discloses a double-valve-clack muffle check valve comprising a valve body (1), a valve rod (4) and a left valve clack (2), wherein the valve rod (4) and the left valve clack (2) are arranged inside the valve body (1), rubber is attached to the surface of the left valve clack (2), the valve body (1) comprises a left flange and a right flange, a valve cover ring (5) matched with the valve body (1) is arranged on the right flange, a right valve clack (3) is arranged outside the right flange and on the valve cover ring (5), and rubber is attached to the surface of the right valve clack (3). The double-valve-clack muffle check valve has the advantages of being good in sealing performance, low in noise, and suitable for various horizontal medium pipelines.
Description
Technical field:
The utility model belongs to valve technology field, particularly oil, chemical industry and water supply level pipeline safety check.
Background technique:
Damping check valve is mainly used on the pipeline of medium one-way flow, only allow medium to flow to a direction, to try to avert accidents, comprise the parts such as valve body (1), valve gap ring (5), valve rod (4), Returnning spring (6), flap, its groundwork principle is the safety check that flap slides along valve rod (4), damping check valve is applicable to be installed on various horizontal pipes, and traditional damping check valve is owing to only have a flap, and its sealability is relatively poor.
Summary of the invention:
Technical problem to be solved in the utility model is that a kind of Double-clack damping check valve of good airproof performance is provided.
To achieve these goals, the utility model has adopted following technical proposal: a kind of Double-clack damping check valve, it comprises valve body (1) and is arranged on the valve rod (4) in the valve body (1), the left flap (2) of surperficial attached rubber, valve body (1) comprises left and right flanges, wherein, described right flange is provided with and valve body (1) proportioning valve bezel ring, (5), is positioned at the right flap (3) that right flange arranged outside has surperficial attached rubber on the valve gap ring (5).
Wherein, it is inboard that described left flap (2) is positioned at left flange, and valve rod (4) runs through the central shaft of left and right flap (2,3), is provided with Returnning spring (6) between left flap (2) and the valve gap ring (5).
Wherein, offer on the described valve gap ring (5) and right flap (3) groove that is complementary.
Wherein, described valve gap ring (5) is screw-thread fit with valve body (1).
Compare with existing safety check, the utility model is owing to the design of employing Double-clack, so that its good seal performance, and have the little characteristics of noise, be applicable to various horizontal medium pipelines.
Below with reference to drawings and Examples, the utility model is described in detail.
Description of drawings
Fig. 1 is this practical double-sealing combination check valve structural representation.
Embodiment
See also Fig. 1, a kind of Double-clack damping check valve, it comprises and offers a left side, the valve body of right flange (1), and the left flap (2) that is positioned at left flange inboard, be arranged on the inner valve rod (4) of valve body (1), right flap (3), be arranged on the right flange outside and be the fixing valve gap ring (5) of trapezoidal thread with valve body (1), be provided with Returnning spring (6) between left flap (2) and the valve gap ring (5), valve gap ring (5) offers groove on the outside, be provided with right flap (3) in the groove, valve rod (4) passes through a left side, right flap (2,3) central shaft, left, right flap (2,3) shape is discoid, and the surface is with corrosion resistant rubber layer, a left side, right flap (2,3) all being screw thread with valve rod (4) is fixedly connected with.Valve rod (4) endwisely slips opening/shutting valve with left flap (2) fixed thereon by the annular distance on valve body (1) and valve gap ring (5).When medium passed through valve body (1), pressure medium promotes left flap (2) thereby moving right compression reseting spring (6) opens the left side valve port, and left flap this moment (2) interlock valve rod (4) moves right, so that right flap (3) moves right the right valve port of unlatching; When medium stopped, Returnning spring (6) stretched promotion valve rod (4) and left flap (2) is closed left valve port to left movement, and valve rod this moment (4) drives right flap (3) and also closes right valve port to left movement.
The utility model adopts the Double-clack design, its good seal performance, and the characteristics that noise is little are applicable to various horizontal medium pipelines.
