Abstract
Present invention discloses a kind of swing check valves, it includes valve body (10), the valve deck (30) being connected with the valve body (10) and the flap component (50) being arranged in the valve body (10), the swing check valve further includes being symmetrically disposed on most valve bodies (10) internal the first valve seat (18) and the second valve seat (19), the flap component (50) is connected with the valve deck (30) and salable first valve seat (18), after valve deck (30) the rotation 180 degree is connect with the valve body (10), salable second valve seat (19) of flap component (50).Swing check valve of the invention, by the way that the flap component being connected with valve deck is arranged, so that the cut-off direction of swing check valve can be changed after valve deck rotates 180 degree;In this way when needing to change cut-off direction, valve deck need to be only dismounted, it is more convenient efficient.
Description
Technical field
The present invention relates to a kind of check-valves, in particular to a kind of swing check valve.
Background technique
Check-valves is used to prevent the refluence of medium in pipeline.When the medium forward flow in pipeline, the flap of check-valves
It is automatically turned under the action of medium power, when the medium reverse flow in pipeline, flap closes automatically under the action of medium power
It closes.Swing check valve is a kind of common check-valves, and the swing check valve of the prior art ends direction after installation is complete
It secures, if necessary to conversion cut-off direction (as there is a situation where swing check valve direction is surprisingly anti-loaded), then needs weight
It is new to remove swing check valve and reinstalled after turning direction, it is inconvenient.
Summary of the invention
It is an object of the invention in view of the above-mentioned drawbacks in the prior art, provide a kind of swing check valve, it is not necessarily to
Remove the i.e. changeable cut-off direction of swing check valve.
For achieving the above object, present invention employs following technical solutions: a kind of swing check valve comprising valve
In the intracorporal flap component of the valve, the swing check valve further includes for body, the valve deck being connected with the valve body and setting
It is symmetrically disposed on the first valve seat and the second valve seat of most valve inners, the flap component is connected and salable with the valve deck
First valve seat, the valve deck rotates by a certain angle connect with the valve body after, the flap component salable described second
Valve seat.
In addition, the present invention also proposes following attached technical scheme:
The flap component includes the connecting column being connected with the valve deck and the valve that is rotatably connected with the connecting column
Valve.
The valve deck is connected with the connecting column by screw.
The flap component further includes the shaft being threaded through between the connecting column and the flap.
The flap is provided with the recessed portion of indent.
The body top is connect with the bonnet flange.
Compared with the prior art, the present invention has the advantages that swing check valve of the invention, passes through setting and valve deck phase
Flap component even, so that the cut-off direction of swing check valve can be changed after valve deck rotates 180 degree;It is needing in this way
When changing cut-off direction, valve deck need to be only dismounted, it is more convenient efficient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of swing check valve of the present invention.
Fig. 2 is that swing check valve of the present invention changes the schematic diagram behind cut-off direction.
Fig. 3 is the structural schematic diagram of flap component in the present invention.
Specific embodiment
In conjunction with the preferred embodiment and its attached drawing is further non-limitingly described in detail technical solution of the present invention.
As shown in Figure 1, corresponding to a kind of swing check valve of preferred embodiment of the present invention comprising valve body 10, valve deck
30 and flap component 50.
Valve body 10 includes water inlet 11, water outlet 12, inner cavity 13 and position between water inlet 11 and water outlet 12
In the opening 14 valve body 10 top and communicated with inner cavity 13.Water inlet 11 is flowed into for medium, is connected with water inlet line,
Valve body 10 is provided with first flange interconnecting piece 15 at water inlet 11;Water outlet 12 is flowed out for medium, with outlet conduit phase
Even, valve body 10 is provided with second flange interconnecting piece 16 at water outlet 12.Valve body 10 is provided with third flange at opening 14 and connects
Socket part 17, for being connected with valve deck 30.Symmetrical first valve seat 18 and the second valve seat 19 are internally provided in valve body 10.
As shown in Fig. 2, flap component 50 includes connecting column 51 and the flap 52 being rotatably connected with connecting column 51.Connection
It is connected with valve deck 30 at the top of column 51 by screw 53, bottom passes through shaft 54 and is connected with flap 52, and flap 52 can around the shaft 54
Smooth rotation.
As shown in Figure 1, flap component 50 is located in inner cavity 13 after valve deck 30 is installed on valve body 10, flap 52 is rigid
Good to abut to the first valve seat 18, the first valve seat 18 has certain tilt angle, enable flap 52 reliably by it is close
Envelope.After medium enters from water inlet 11, flap 52 will be pushed open and flowed out from water outlet 12, and prevent medium from flowing back from water outlet 12
To water inlet 11;Need to change cut-off direction when, only need to by valve deck 30 rotate 180 degree be installed (it is understood that into
When horizontal plane angulation is not 180 degree, the rotational angle of valve deck 30 is no longer 180 degree for the mouth of a river 11 and 12 axis of water outlet,
But 12 axis angulation of water inlet 11 and water outlet), as shown in figure 3, flap 52 will be abutted to the second valve seat 19 at this time
On, so that medium can only be flowed into from water outlet 12, flowed out from water inlet 11.In this way, without the first method for dismounting 10 two sides of valve body
Blue interconnecting piece 15 and second flange interconnecting piece 16 need to only dismount valve deck 30, more convenient efficient.
In the present embodiment, it is provided centrally with the recessed portion 56 of indent in flap 52, in this way, it is only necessary to guarantee 52 surface of flap
Be in contact the precision at position with the first valve seat 18, the second valve seat 19, reduces the processing cost of flap 52.
Swing check valve of the invention, by the way that the flap component being connected with valve deck is arranged, so that rotating 180 degree in valve deck
Afterwards, the cut-off direction of swing check valve can be changed;In this way when needing to change cut-off direction, valve deck only need to be dismounted,
It is more convenient efficient.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
