Description
Technical field
The utility model relates to a kind of valve more particularly to a kind of non-return valves.
Background technique
Currently, the effect of non-return valve is only fluid media (medium) to be allowed to flow to a direction, and prevent fluid media (medium) negative side
To flowing.In use, non-return valve is automatic work, when fluid media (medium) fair current, flap pushes flap rotation by fluid media (medium),
And open the non-return valve；When fluid media (medium) arrheas, flap, which leans against to turn under its self weight left and right, cuts off media flow on valve seat,
To close the non-return valve；But since this kind of non-return valve realizes cutting fluid media (medium) flowing, installation due to being self-possessed by flap
When, need to consider the gravity direction of flap, and non-return valve is caused to be only capable of by the way of being horizontally mounted, that is, lead to making for non-return valve
Compare limitation with environment.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of non-return valves, pass through guiding
Flap cutting fluid media (medium) flowing is realized in the cooperation of part, guide rod and elastic element, and then expands its use environment.
The purpose of this utility model adopts the following technical scheme that realization:
A kind of non-return valve, including valve body, flap, elastic element, guide part and baffle；The baffle is fixed on the valve body
It is interior, offer water inlet；The flap is movably arranged in the valve body, and can in the closed position for blocking the water inlet and
It is moved between open position far from the water inlet；The elastic element promotes flap to move to the close stance for providing
The elastic stress set；The guide part is fixed in the valve body, and offers guide groove；The guide groove is along the flap
Moving direction extends；The guide rod that activity is plugged in the guide groove is fixed on the flap.
Further, the valve body is L-shaped.
Further, the first binding face is formed on the baffle；The second binding face is formed on the flap；Described
Two binding faces are bonded with the first binding face movable closed so that the flap blocks the water inlet.
Further, the flap is flexible disk.
Further, one end of the valve body is formed as water inlet end, and the other end is formed as water outlet；The baffle and described
Flap is arranged successively from the water inlet end to the water outlet extreme direction.
Further, the water inlet end offers external screw thread.
Further, the non-return valve further includes installation part；The installation part is fixed in the valve body, and the installation
Part and the baffle are placed in the two sides of the guide part；The elastic element is spring, and the both ends of the spring are fixed respectively
On the guide part and the flap.
Further, the installation part is gasket, and the gasket is through with outlet pass.
Compared with prior art, the utility model has the beneficial effects that:
The utility model guides the direction of motion of flap by using the cooperation of guide part and guide rod, later in elastic element
Elastic stress effect under promote flap move to block water inlet closed position, and realize close the non-return valve, it is relatively existing
Some non-return valves need not rely on flap self gravity and realize closing, realize the gravity direction for being not necessarily to consider flap during installation,
And then it is applicable to wider use environment.

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of non-return valve as shown in Figs. 1-2, including valve body 10, flap 20, elastic element 30, guide part 40 and baffle
50；Baffle 50 can be fixed in valve body 10 by modes such as gluing, clampings, and offer water inlet 52 on the baffle 50；It should be into
The mouth of a river 52 flows in valve body 10 for external water；The flap 20 is movably arranged in valve body 10, and can block the water inlet 52
Closed position and far from the water inlet 52 open position between move；Elastic element 30 promotes flap 20 to move for providing
To the elastic stress of the closed position；The guide part 40 is fixed in valve body 10 by modes such as gluing, clampings, and is being oriented to
Guide groove 41 is opened up on part 40；The guide groove 41 extends along the direction of motion of the flap 20；Movable inserting is fixed on flap 20
Guide rod 60 in the guide groove 41 can be greater than the diameter of guide rod 60 by the diameter of guide groove 41 to realize guide rod 60 herein
Activity is plugged in guide groove 41.
On the basis of above structure, when using this non-return valve, this non-return valve is connected to outer water tube, in Fig. 2
Shown in arrow, external fluid flows to water inlet 52, is greater than the bullet that elastic element 30 acts on flap 20 in the hydraulic pressure of external fluid
Property stress when, push flap 20, flap 20 is under the cooperation guiding of guide groove 41 and guide rod 60 to far from water inlet 52 at this time
Direction is mobile, realizes and opens this non-return valve；Simultaneously, when closing external fluid, the elastic stress of elastic element 30 is acted on
Flap 20, and promote flap 20 under the cooperation guiding of guide groove 41 and guide rod 60, move to the close stance for blocking water inlet 52
It sets, that is, realizes and close this non-return valve；In above structure, it is real to need not rely on 20 self gravity of flap for relatively existing non-return valve
It now closes, realizes during installation without considering the gravity direction of flap 20, and then be applicable to wider use environment.
Above-mentioned valve body 10 can be I type or L-type.
Above-mentioned flap 20 can be by being plugged in water inlet 52, and the mode for blocking water inlet 52 blocks the water inlet
52, and the present embodiment preferably tries lower embodiment, is formed with the first binding face 51 on baffle 50；The second patch is formed on flap 20
Conjunction face 21；Second binding face 21 is bonded with 51 movable closed of the first binding face so that flap 20 blocks water inlet 52, in this way, can keep away
It is stuck in water inlet 52 to exempt from flap 20.
It is highly preferred that flap 20 is flexible disk；In this way, acting on flap 20, the second patch in elastic element 30
When conjunction face 21 is bonded with the first binding face 51, deformation occurs for flap 20, and can make the second binding face 21 and the first binding face 51 more
Stick on conjunction, improves leakproofness；Furthermore when reverse flow of fluids in valve body 10, play the role of buffer fluid, reduces impact；Tool
Body, above-mentioned flap 20 can be existing sucker, flexible glue disk etc..
Specifically, one end of valve body 10 is formed as water inlet end, and the other end is formed as water outlet；Baffle 50 and flap 20 from into
Water end (W.E.) is arranged successively to water outlet extreme direction.
Furthermore water inlet end offers external screw thread 11, which realizes this non-return valve convenient for being spirally connected with external lug
Installation.
Further, this non-return valve further includes installation part 70；Installation part 70 is fixed in valve body 10, and installation part 70 and gear
Plate 50 is placed in the two sides of guide part 40；Elastic element 30 is spring, and the both ends of spring are separately fixed at guide part 40 and flap
On 20, simple installation；Furthermore the elastic element 30 can be elastic slice, Elastic force post etc..
The installation part 70 is gasket, and gasket is through with outlet pass, which passes through for fluid；Laminated structure weight compared with
Gently, the overall weight that can be further decreased weight, and then reduce this non-return valve is opened up and by mouth；Furthermore the installation part 70
It can be mounting rod, mounting plate etc..
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
