Between accompany rubber seal conical sleeve and spool, be provided with outer annular distance and inner via hole on spool, reinforcing rib be equipped on the downside of outer annular distance muscle,
Inner via hole includes the conus portion of top and the cylindrical portion of lower section, and the cylindrical portion of inner via hole is equipped with a circle round tube hole, the circle of inner via hole
Tapering is equipped with a circle bellmouth, and valve body side is equipped with the holding screw for preventing valve internals from sliding;
When medium clockwise direction flows, medium pushes rubber seal conical sleeve to move up, and rubber seal conical sleeve rises slightly;
Medium reverse direction flow when, medium push rubber seal conical sleeve move down, rubber seal conical sleeve retraction and
Sealing is closely pressed with spool.
Further, the valve body is equipped with arrow shaped medium sign, and arrow shaped medium sign indicates Jie
Mass flow to.
Relative to the prior art, clamped silencing check valve of the present invention has the advantage that:Pass through rubber seal
Enclose the non-return sealing function that tapered sleeve realizes valve noiseless and valve with spool cooperation.Valve also have flow resistance coefficient it is low, installation
The advantages that convenience, good seal performance, simple in structure, function-stable.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the invention can
To be combined with each other.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " on ", " under ",
The orientation or position relationship of the instructions such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " are
Based on orientation shown in the drawings or position relationship, it is for only for ease of description the invention and simplifies description rather than instruction
Or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore be not understood that
For the limitation to the invention.In addition, term " first ", " second " etc. are only used for description purpose, and it is not intended that instruction
Or imply relative importance or the implicit quantity for indicating indicated technical characteristic." first ", " second " etc. are defined as a result,
Feature can express or implicitly include one or more this feature.In the description of the invention, unless separately
It is described, " multiple " are meant that two or more.
In the description of the invention, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally
Connection;Can be mechanical connection or electrical connection;It can be directly connected, can also be indirectly connected by intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
The technical program the technical problem to be solved is that:Existing check-valves is closed spool 5 in medium counter flow and can be produced
Raw larger noise.
In order to solve the above-mentioned technical problem, as shown in Figs. 1-3, a kind of clamped silencing check valve is present embodiments provided,
Including valve body 1, upper trim ring sheath body 2 and lower clamping ring sheath body 6, upper 2 outer surface of trim ring sheath body is equipped with upper vulcanised rubber layer 3, lower clamping ring
6 outer surface of sheath body is equipped with lower vulcanised rubber layer 7, and rubber seal conical sleeve is accompanied between upper trim ring sheath body 2 and lower clamping ring sheath body 6
4 and spool 5, outer annular distance and inner via hole are provided on spool 5, are equipped with reinforcing rib on the downside of outer annular distance muscle, reinforcing rib can enhance spool 5
Pressure-bearing bending resistance, the conus portion of inner via hole including top and the cylindrical portion of lower section, the cylindrical portion of inner via hole are equipped with a circle and justify
Through-hole, the conus portion of inner via hole are equipped with a circle bellmouth, and flow when bellmouth can increase valve opening simultaneously reduces flow resistance coefficient,
1 side of valve body is equipped with the holding screw 8 for preventing valve internals from sliding, and holding screw 8 can especially prevent valve in transportational process
Middle valve internals slide;When medium clockwise direction flows, medium pushes rubber seal conical sleeve 4 to move up, rubber seal circular cone
Set 4 rises thick;When medium reverse direction flows, medium pushes rubber seal conical sleeve 4 to move down, and rubber seal conical sleeve 4 bounces back
And closely pressed with spool 5, realize the noiseless closing of valve and non-return sealing function.As shown in figure 3, the valve body 1 is equipped with
Arrow shaped medium sign, arrow shaped medium sign indicate that medium flows to.
When valve is installed on pipeline, holding screw 8 is first unscrewed, flange bolt is being screwed by specification, by two methods
Blue pinch valve internals, moreover, not having to add flange gasket during installation, because of upper trim ring sheath body 2 and 6 internal diameter of lower clamping ring sheath body and side
Face has securely vulcanized one layer of rubber, i.e., upper vulcanised rubber layer 3 and lower vulcanised rubber layer 7, upper vulcanised rubber layer 3 and lower vulcanization
Rubber layer 7 can realize flange seal and the sealing of valve internals.
The technical solution that the embodiment is provided has the technical effect that:Reality is coordinated by rubber seal tapered sleeve and spool 5
The non-return sealing function of existing valve noiseless and valve.Valve also has low flow resistance coefficient, easy for installation, good seal performance, knot
The advantages that structure is simple, function-stable.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
