Description
Technical field
This utility model belongs to pipe transportation technology field, relates to a kind of check-valves, particularly a kind of non-return valve.
Background technology
Check-valves refers to rely on medium itself to flow and automatic open and close flap, is used for the valve preventing medium from flowing backwards, 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
Stream, prevent pump and drive motor reversion, and the releasing of vessel media.It is presently used for preventing the check valve design of aqueous reflux
Loaded down with trivial details, cost is high, complex manufacturing, and airtight quality is the most unstable.Therefore, a kind of production technology is needed badly simple, cost
Cheap, airtight quality is good, can effectively stop the check-valves of the refluence of water in pipeline.
Summary of the invention
The purpose of this utility model is to provide a kind of non-return valve, and this non-return valve production technology is simple, it is simple to
Installing and using, valve closing is tight, good sealing effect, can effectively stop the refluence of water in pipeline, have high use value.
The purpose of this utility model is achieved in that a kind of non-return valve, including valve body, valve pocket, water inlet, water outlet
Mouth, netted baffle plate, valve ball, the water inlet of described valve body connects water inlet pipe, and the outlet of described valve body connects water outlet
Pipe, described valve body has a spherical valve pocket expanded, is fixed with netted baffle plate, has one in described valve pocket in described valve pocket
Valve ball, described valve ball is between water inlet and netted baffle plate.
The diameter of described valve ball is more than the diameter of water inlet.
Described valve ball is the high molecule plastic valve ball with certain rigidity, and the density of valve ball is more than the density of water.
Being uniform-distribution with a lot of mesh on described netted baffle plate, the diameter of mesh is less than the diameter of valve ball.
Described valve pocket is bonding with a circle sealing gasket above water inlet one end.
This utility model produces and provides the benefit that: a kind of non-return valve, is fixed with a netted baffle plate, net in valve pocket
There is a lot of mesh above shape baffle plate, do not hinder passing through of current, between netted baffle plate and valve pocket water inlet, have a valve ball, due to
The diameter of valve ball is bigger than water inlet diameter, and valve ball is limited in the cavity area between netted baffle plate and valve pocket water inlet.When having
Current are by time in water inlet entrance valve pocket, and valve ball is backed down by current, and current can pass freely through；When current flow backwards, valve ball
It is tightly pressed at valve pocket water inlet by current, stops current to flow backwards, further, since there is a circle sealing gasket valve pocket water inlet one end,
Make the contact between valve ball and valve pocket tightr, play preferably sealing process.
Accompanying drawing explanation
Fig. 1 is the structural representation during unlatching of this utility model valve ball.
Fig. 2 is the structural representation during closedown of this utility model valve ball.
Fig. 3 is the top view of the netted baffle plate of this utility model.
In figure: 1, valve body 2, valve pocket 3, water inlet 4, outlet 5, netted baffle plate 6, valve ball 7, sealing gasket 8, water
Flow path direction 9, mesh.
Detailed description of the invention
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment 1
As illustrated in the accompanying drawings from 1 to 3, a kind of non-return valve, including valve body 1, valve pocket 2, water inlet 3, outlet 4, netted baffle plate
5, valve ball 6, the water inlet 3 of described valve body 1 connects water inlet pipe, and the outlet 4 of described valve body 1 connects outlet pipe, institute
The valve body 1 stated has a spherical valve pocket 2 expanded, and is fixed with netted baffle plate 5, has one in described valve pocket 2 in described valve pocket 2
Valve ball 6, described valve ball 6 is between water inlet 4 and netted baffle plate 5.
The diameter of described valve ball 6 is more than the diameter of water inlet 4.
Described valve ball 6 is the high molecule plastic valve ball with certain rigidity, and the density of valve ball 6 is more than the density of water.
Being uniform-distribution with a lot of mesh 9 on described netted baffle plate 5, the diameter of mesh 9 is less than the diameter of valve ball 6.
Described valve pocket 2 is bonding with a circle sealing gasket 7 above water inlet 3 one end.
This utility model is in use: a kind of non-return valve, connects, water inlet and the water inlet pipe of valve body by valve body
Outlet and outlet pipe connect, and fixedly mount a netted baffle plate in valve pocket, and netted baffle plate has a lot of meshes, it is ensured that current are not
Interrupted passes through baffle plate；Having a spherical valve ball between netted baffle plate and water inlet, valve ball is the plastics of macromolecular material
Valve ball, density is slightly larger than the density of water, it is ensured that valve ball has certain buoyancy.When current forward passes through, current can push valve ball open,
Making valve ball move to the direction of netted baffle plate, due to the existence of netted baffle plate, valve ball is blocked, it is to avoid valve ball blocking water outlet
Mouthful；When flow reversal in pipeline, the current of adverse current can promote valve ball to move to valve pocket water inlet, owing to the diameter of valve ball is big
In the diameter of water inlet, water inlet is blocked by valve ball, additionally under the effect of sealing gasket, and valve ball and valve pocket firm contact, thus
Prevent the refluence of water in pipeline.
Generally, this utility model has simple in construction, manufactures easy for installation, and airtight quality is good, can effectively stop pipeline
The advantage of the refluence of interior water.
