The utility model discloses a set up damping ring on the sealed face on the disk seat, the valve clack has increased the life of valve clack and disk seat to the impact force of valve seat seal face in the time of can reducing the valve and close, and simultaneously, the setting of cutting ferrule can make things convenient for the dismantlement of disk seat.

Description

The spacing vibration damping check-valves of the wear-resisting cutting ferrule of axial-flow type
Technical field
The utility model relates to valve technology field, more specifically, particularly relates to a kind of axial-flow type resistance toThe spacing vibration damping check-valves of mill cutting ferrule.
Background technology
Check-valves is quite general in the prior art, but technical what check-valves was controlledAlso there is certain room for improvement, due to the Structure Designing Problem of existing check-valves, check-valves in the time closing,Flap is very large to the impulsive force of valve seat, can reduce like this service life of flap and valve seat, and this is needsImproved problem.
Utility model content
In view of the above, the purpose of this utility model is to provide the wear-resisting cutting ferrule of a kind of axial-flow type spacing vibration dampingCheck-valves, for solving prior art check-valves flap in the time cutting out problem very large to the impulsive force of valve seat.
For achieving the above object and other relevant objects, the utility model provides following technical scheme:
The spacing vibration damping check-valves of a kind of wear-resisting cutting ferrule of axial-flow type, comprises valve body, kuppe, flap axle, bufferingSpring, flap and valve seat, valve body is provided with valve import and valve outlet port, and valve seat is fixed on the inwall of valve import, leadsStream cover is fixed on valve interior wall, and flap axle one end is fixed on kuppe center by the first lining, and flap axle is anotherOne end is fixed on valve seat center by the second lining, and flap is arranged on flap axle, and buffer spring is arranged on valveOn lobe axle, buffer spring one end is fixedly connected with flap, and the buffer spring other end is fixedly connected with kuppe,Described valve seat is provided with the sealing surface that can seal with flap, and described sealing surface is provided with shock ring, and described valve entersMouth inwall is also detachably provided with the cutting ferrule for locating valve seat.
Further, described cutting ferrule is the circular ring structure of the first circular arc and the second circular arc composition, described the second circular arcTwo openends and two openends of the first circular arc be connected by screw.
As mentioned above, the utlity model has following beneficial effect: by the medium back flow in valve body to flapThe pressure producing, thus realize closure of check ring, on the sealing surface on valve seat, damping ring is set, canThe impulsive force of flap to sealing surface of seat while reducing valve closing, has increased service life of flap and valve seat,Meanwhile, the setting of cutting ferrule can facilitate the dismounting of valve seat.
Brief description of the drawings
In order to be illustrated more clearly in the scheme in the utility model embodiment, below will be in specific embodimentThe accompanying drawing of describing required use is briefly described, and apparently, the accompanying drawing in the following describes onlyBe embodiment more of the present utility model, for those skilled in the art, do not paying creative laborUnder moving prerequisite, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of cutting ferrule;
The structural representation that Fig. 3 valve seat coordinates with flap.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodimentBe clearly and completely described, obviously, described embodiment is only that a part of the present utility model is realExecute example, instead of whole embodiment. Based on embodiment of the present utility model, those of ordinary skill in the artAll other embodiment that obtain under the prerequisite of not making creative work, belong to the utility modelThe scope of protection.
Please refer to Fig. 1, Fig. 3, the spacing vibration damping check-valves of the wear-resisting cutting ferrule of a kind of axial-flow type of the present embodiment comprises valveBody 1, kuppe 10, flap axle 5, buffer spring 3, flap 6 and valve seat 8, valve body 1 is provided with valve import11 and valve outlet port 12, valve seat 8 is fixed on the inwall of valve import 11, and kuppe 10 is fixed in valve body 1Wall, flap axle 5 one end are fixed on kuppe 10 centers by the first lining 2, and flap axle 5 other ends are logicalCross the second lining 7 and be fixed on valve seat 8 centers, flap 6 is arranged on flap axle 5, and buffer spring 3 arrangesOn flap axle 5, buffer spring 3 one end are fixedly connected with flap 6, buffer spring 3 other ends and water conservancy diversionCover 10 is fixedly connected with, and described valve seat 8 is provided with the sealing surface 13 that can seal with flap, described sealing surface 13Be provided with shock ring 14, described valve import 11 inwalls are also detachably provided with the cutting ferrule 9 for locating valve seat 8.
As shown in Figure 2, particularly, described cutting ferrule 9 is the circle that the first circular arc 91 and the second circular arc 92 formRing structure, two openends of two openends of described the second circular arc 92 and the first circular arc 91 are by screw 93Connect.
Incorporated by reference to Fig. 1, the principle of such scheme is, when there being medium to be entered by valve import 11 places of valve body 1When valve body 1 is interior, the pressure of medium itself can promote flap 6 and push buffer spring 3, thereby makes medium pass through valveLobe 6 enters in valve body 1, is smoothly through valve body 1 thereby realize medium; When the medium that enters valve body 1 reducesOr while stopping, the pressure that promotion flap 6 pushes buffer spring 3 diminishes, in the reaction of buffer spring 3Pressure medium in power and valve body 1 will promote flap 6 and move towards valve seat 8, when flap 6 leans on completely surelyOn sealing surface 13 on valve seat 8 time, shock ring 14 will reduce the sealing surface 13 of flap 6 to valve seat 8Impulsive force, medium will end flow.
In sum, the utility model has been realized the adjusting to closure of check ring speed very dexterously. So,The utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
