Abstract
One kind sealing check-valves, including valve body, bonnet, flap；The valve body is hollow circular cylinder, both ends are respectively inflow entrance, flow export, valve body vertically forms cavity, in the bonnet insertion cavity, valve interior wall is located at cavity lower end fixed rotating shaft, and the flap is rotatably connected by rotating shaft and valve interior wall, and the valve interior wall sets annular groove with valve flap contacts face, projection corresponding with annular groove is set on flap, and the projection is inserted in annular groove.Pass through annular groove and projection corresponding to the setting on valve body, flap, in projection insertion annular groove, so as to can be effectively by flap by valve seal when reverse fluid flow in valve body, the valve rod moved up and down is further set on bonnet, the uninterrupted of valve body is flowed through by controlling the opening angle of flap to control.
Description
Technical field
It the utility model is related to valve body technical field, and in particular to one kind sealing check-valves.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.Check-valves can also be used to rise to pressure therein
There is provided to the accessory system for exceeding system pressure on the pipeline of supply.Check-valves can be divided mainly into swing check valve and (be revolved according to center of gravity
Turn) and lift check valve (being moved along axis).The effect of check-valves is only to allow medium to be flowed to a direction, and is prevented
Opposite direction flows.Usual this valve is worked automatically, and under the Fluid pressure effect flowed in one direction, flap is opened；
When fluid opposite direction flows, valve seat is acted on by the gravity closing flap of Fluid pressure and flap, so as to cut off flowing.But mesh
A problem existing for the check-valves of preceding in the market is that flap can not generally act on valve seat shape when opposed flow occurs for fluid
Into preferable sealing, this can not meet to require for the higher occasion of sealing requirements.Even if fluid is in forward flow simultaneously
Flap is opened also can the certain resistance of convection body generation.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided one kind sealing non-return
Valve.
Technical problem to be solved in the utility model is realized using following technical scheme：
One kind sealing check-valves, including valve body, bonnet, flap；The valve body is hollow circular cylinder, and both ends are respectively to flow into
Mouth, flow export, valve body vertically form cavity, and the bonnet is inserted in cavity, and valve interior wall, which is located at cavity lower end, to be fixed
Rotating shaft, the flap are rotatably connected by rotating shaft and valve interior wall, it is characterised in that：The valve interior wall and valve flap contacts face
Annular groove is set, projection corresponding with annular groove is set on flap, the projection is inserted in annular groove.
The bonnet is provided with the through hole of internal thread, and valve rod is through the through hole and can be moved up and down along the through hole.
By valve rod move up and down control flap opening angle, so as to control the uninterrupted for flowing through valve body.
Sealing ring is set in the annular groove, further by flap and valve seal.
The cavity diameter is more than flap diameter, reduces fluid when valve interior wall flows because of resistance caused by flap.
The beneficial effects of the utility model are：Pass through annular groove and projection, projection corresponding to the setting on valve body, flap
Insert in annular groove, so as to can be effectively by flap by valve seal, further when reverse fluid flow in valve body
The valve rod moved up and down is set on bonnet, the uninterrupted of valve body is flowed through by controlling the opening angle of flap to control.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of sealing check-valves, including valve body 1, bonnet 5, flap 7；Valve body 1 is hollow circular cylinder, both ends
Respectively inflow entrance 2, flow export 3, valve body 1 vertically form cavity 4, and bonnet 5 is inserted in cavity 4, and the inwall of valve body 1 is located at
The lower end fixed rotating shaft 6 of cavity 4, flap 7 are rotatably connected by rotating shaft 6 and the inwall of valve body 1, the inwall of valve body 1 and the contact surface of flap 7
Annular groove 8 is set, projection 9 corresponding with annular groove 8 is set on flap 7, projection 9 is inserted in annular groove 8, so that
Flap 7 seals valve body 1, sets sealing ring 10 to further function as sealing function in annular groove 8, the diameter of cavity 4 is more than valve
The diameter of valve 7, fluid can be reduced when the inwall of valve body 1 flows because of resistance caused by flap 7, bonnet 5 is provided with internal thread
Through hole 11, valve rod 12 passes through through hole 1, by valve rod 12 the opening angle for moving up and down control flap 7, so as to controlling stream
Cross the uninterrupted of valve body 1.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
