Description
Technical field
The utility model relates to built-in type opposite clip back valves.
Background technique
It is using the automatic valve for preventing medium counter flow in the duct to folder connection, due to the closing of flap to folder check-valves
Stroke is short, and has spring loads, can substantially reduce water hammer.It is usually used in city, industry and skyscraper water supply, drainpipe
On the net.And its structure length is shorter than general check-valves, is applicable in the most the place for having installation space to limit.Check-valves is in pipeline
In purpose be prevent medium counter flow, once the reason is that medium counter flow will cause unnecessary loss, it is seen that the sealing of check-valves
Performance is very important, in certain pipelines, once check-valves leakage or adverse current can cause consequence very serious, even
The life security of people may be threatened.
Summary of the invention
The utility model provides a kind of structure simple, easy for installation, to good airproof performance built-in type opposite clip back valve.
In order to solve the above technical problems, the utility model uses a kind of following technical scheme: built-in type opposite clip back valve, packet
Valve body, flap, pin shaft and torsional spring are included, the valve body is equipped with axle sleeve slot, and axle sleeve is equipped in the axle sleeve slot, and the axle sleeve is used
In fixed pin shaft, the pin shaft is equipped with locking plate and screw for fixing flap and torsional spring, axle sleeve upper end, and the locking plate is equipped with convex
It rises, the valve body is equipped with locked groove, and the protrusion is matched with locked groove, and the screw is matched by protrusion with locked groove, by axis
Set is fixed on valve body.
The beneficial effects of the utility model are: flap and torsional spring are fixed on pin shaft, then pin shaft both ends are used when assembly
Axle sleeve is fixed, then axle sleeve slot of the axle sleeve on valve body is put into valve body, then be put into locking plate in above axle sleeve, makes protrusion and locked groove phase
Cooperation, is finally screwed in valve body, whole installation process is very convenient, compared to traditional external fixed pin shaft of screw
Mode, the utility model, which is used instead, puts the mode fixed pin shaft that axle sleeve locks piece, and all parts are packed into valve from valve latus rectum position
Body ensure that the globality of valve body, avoids punching on valve body, prevents to leak outside.
Further, the flap is symmetrical arranged by two flaps, and the angle under two flap full-gears is 20 degree, by
Bigger in full-gear flap angle, bigger to the resistance of media flow, the pressure loss is necessarily bigger, and when angle is too small,
Flap is in dynamic equilibrium state under the collective effect of medium and torsional spring, is easy to happen vibration, causes the secondary turbulent flow of medium and whirlpool
Whirlpool, energy loss increases, and when showing that two flap fully open position angles are 20 degree by testing repeatedly, the pressure loss is minimum, simultaneously
It will not cause secondary turbulent flow and whirlpool.
The utility model offer is further described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of built-in type opposite clip back valve provided by the utility model.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of built-in type opposite clip back valve provided by the utility model, including valve body 1, flap 2, pin
Axis 3 and torsional spring 4, the valve body 1 are equipped with axle sleeve slot 5, axle sleeve 6 are equipped in the axle sleeve slot 5, the axle sleeve 6 is for fixing
Pin shaft 3, the pin shaft 3 are equipped with locking plate 7 and screw 8 for fixing flap 2 and torsional spring 4,6 upper end of axle sleeve, and the locking plate 7 is equipped with
Protrusion 9, the valve body 1 are equipped with locked groove 10, and described raised 9 match with locked groove 10, and the screw 8 passes through protrusion 9 and locked groove
10 match, and axle sleeve 6 is fixed on valve body 1, and the flap 2 is symmetrical arranged by two flaps 2, two 2 full-gears of flap
Under angle be 20 degree.
