Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Description.Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is based on
The embodiments of the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments are fallen within the protection scope of the utility model.
Embodiment 1
As shown in Figure 1, a kind of drainage valve arrangement provided by the utility model, the drainage valve arrangement includes flap 1, described
Flap 1 includes capping 2, lower connecting pin 3, and lower 3 inner surface of connecting pin is equipped with connection structure, for flap 1 to be fixed on appearance
Device opening；The capping 2 is equipped with relief hole, is equipped with duckbill valve 4 in the relief hole.As shown in Figure 2 and Figure 3, the duckbilled
4 one end of valve is big, and one end is small, and to installing inside container, the duckbill valve 4 is made of elastic material for small one end, and top is connection
Structure makes gas inside and outside container be connected；The drainage valve arrangement further includes upper connecting pin 5, the upper connecting pin 5 and capping 2
Upper connecting hole is connected, for being connected to drainage tube；A upper cover 6 is additionally provided on the flap 1, the upper cover 6 passes through connector
It is connected on flap 1, the upper cover 6 matches with upper 5 outer diameter of connecting pin, for covering in connecting pin, seals.
Alternatively, top is cylindricality, and lower part is taper as shown in figure 4,6 section of the upper cover is in " ┗ ┙ " font.Lid mouth with
Upper connecting pin 5 is interference fit, and cover port is horizontal end face, and the upper end of upper connecting pin 5 is against on horizontal end face, plays sealing and makees
With.
Drainage valve arrangement has an ellipse circular hole, and Duckbill valve is inserted into the hole, and drainage valve arrangement can be used as lid and cover
It fills on the plastic barrel of additive, upper cover 6 is connected on flap 1 by connector, the upper cover 6 and upper 5 outer diameter phase of connecting pin
Matching, for covering in connecting pin, seals.
As shown in figure 5, being toppled in a 2 gallon volume plastic barrels using flow guiding structure provided by the utility model
When liquid, addition program is completed from starting to be poured into, it is only necessary to which about 30 second time, time are obviously shortened, and improve efficiency, and subtract
The light working strength of worker.
When toppling over plastic barrel liquid, the Duckbill valve plays balance bucket external and internal pressure, keeps flow rate of liquid steady, quickly and not
It can generate and backflow and splash stream.The plastic barrel for filling liquid is that have plastic drum lid screw thread, usually tightens drainage when shutting when not in use
Valve arrangement does not make liquid in bucket leak.Upper cover 6 need to be only opened when output liquid, make the upper connecting pin 5 and the plastics that drain valve arrangement
Drainage tube is connected, and elongates plastic telescopic pipe and protrudes into fuel tank fluid injection.After, drainage tube is pulled up, upper cover 6 is covered, such as Fig. 6
It is shown.
In the prior art, the lid of plastic barrel is matched with plastic barrel, and flow guiding structure and drainage tube are by hot melt side
What formula linked together, when use, needs first to open the lid of plastic barrel, then is inclined by flow guiding structure, a drainage tube
.Operation has following problems in this way:
1, flow guiding structure is not provided with duckbill valve 4, and flow velocity is slow, and the time is long, is very laboriously for Automobile Service worker.
2, additive is only toppled over by diversion pipe, is easy to appear flow velocity shakiness, reflux, splashes the problems such as stream, reduction comes into force
Efficiency, at high cost, safety is low.
3, since the cooperation of plastic barrel and lid is a kind of special structure, different from conventional threaded connection, plastic barrel
Interface, lower end be a conical surface, lid is also the conical surface corresponding with plastic barrel in the lower end of screw thread, back out lid or
Person will extremely exert oneself when tightening lid, grown lid using the time and be easily damaged, and lead to leakage or gaseous volatilization.
If 4, flow guiding structure and drainage tube hot melt technique have deviation, it is easy to cause and gap occurs, connect blow-by, topple over
When can leakage.
The duckbill valve 4 provided in the present embodiment is made of silica gel, and one end is big, and one end is small, and big one end is equipped with limit convex
It rises and is connected to a fixed with capping 2, the connection type of small one end prolate, shape in the form of a duckbill, the duckbill valve 4 and capping 2 was
It is full of mating connection.
Drainage valve arrangement provided by the utility model, using duckbill valve 4, when toppling over plastic barrel liquid, the Duckbill valve is played
Bucket external and internal pressure is balanced, keeps flow rate of liquid steady, quickly and will not generate and backflow and splash stream.Also, it since structure changes, saves
The lid of plastic barrel, also avoids the problem of lid is often screwed down or tightened.Heat-welding process is lacked in production, cost is big
It is big to reduce.
Embodiment 2
Further, described in order to further increase the connection provided by the utility model for draining valve arrangement and drainage tube
Upper connecting pin 5(i.e. and drainage tube connector position) with drainage tube be interference fit connection, the upper connecting pin 5 is equipped at intervals at least
One annular protrusion, the drainage tube are connected thereto part and match equipped with ring structure with the annular protrusion.
Using the structure of second ring slot and two annular protrusions in the present embodiment, it connect drainage valve arrangement more with drainage tube
Closely, formation is gap-free sealed, guarantees that the liquid in plastic barrel will not leak.
Embodiment 3
Further, use for convenience, the upper cover 6 is plug connection with upper connecting pin 5, the upper connecting pin 5 with
Upper cover 6 is interference fit connection, and the upper cover 6 is connected thereto part and matches equipped with ring structure with the annular protrusion.
Drainage valve arrangement provided by the utility model, upper cover 6 are connect with upper connecting pin 5 by connect-disconnect structure, can also be made
With other structures, such as threaded connection, but if being to be threadedly coupled, then the screw thread at upper connecting pin 5 will be connect with drainage tube
Annular groove it is arranged apart, cannot be overlapped, also, upper cover 6 need to be rotatably attached on connector.
As a preference, based on the above-mentioned technical proposal, in order to more convenient to use, described connector one end is fixed present
On lid 1, the other end connects upper cover 6, and the connector is bar shaped, and one end width connecting with flap 1 is less than it and connect with upper cover 6
One end width.The benefit designed in this way is 1) to save material；2) both ends thickness is had any different, and makes to open more convenient.
As a preference, the flap 1, upper connecting pin 5, connector and upper cover 6 are structure as a whole.
3 inner surface of lower connecting pin is equipped with screw thread, and lower connecting pin 3 is a boss, the plastics with plastic barrel junction
The pour spout top of bucket is withstood in the boss plane, and the boss and duckbill valve 4 form twice leakage-proof structure, guarantees that flap 1 is close
Sealing property is good, and in a non-operative state, even if plastic barrel is toppled over, the liquid in bucket will not overflow.
The utility model is created the application mode and can be adjusted according to the actual situation, is not practical for limiting
Novel creation.Technical solution provided by the utility model is described in detail above；The explanation of the present embodiment is only used
The method of the utility model is understood in help.Application mode described in the utility model can be adjusted according to the actual situation, and
