Description
Technical field
This utility model relates to a kind of valve, is specifically related to a kind of wafer type full-bore soft seal water impact preventing check-valves.
Background technology
Check-valves is also known as check valve or non-return valve, and its effect is to prevent the medium in pipeline from flowing backwards, and opening and closing element leans on medium stream
Dynamic and strength is turned on and off voluntarily, to prevent valve that medium flows backwards on check-valves.Check-valves belongs to automatic valve class, mainly uses
On the pipeline of medium one-way flow, medium is only allowed to flow to a direction, to try to avert accidents.
But the common Wafer Check Valves that firmly seals, in the case of in use pressure is little, flap and valve body it
Between there is certain gap, it may appear that seepage, and negotiability is poor；And the flap of common soft seal Wafer Check Valves is all
Being planar designs, its vertical is big, high to the thickness requirement of flap, seepage the most easily occurs, and easily occurs
Water hammer, has noise big, the shortcoming of sealing effectiveness difference.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of wafer type full-bore soft seal water impact preventing non-return
Valve, mainly solves the problems such as check valve sealing is poor, noise is big, this wafer type full-bore soft seal water impact preventing check valve seal
Performance is good, and negotiability is strong, and flap design is spherical shape, can be thus thinning with the disperse medium vertical to flap
Flap thickness, saves material, and spherical shape facilitates current to pass through, thus it also avoid water hammer, have with low cost,
Practical and convenient, it is easy to the advantages such as popularization.
This utility model be the technical scheme is that a kind of wafer type full-bore soft seal water impact preventing check-valves, including
Valve body and valve seat, offer latus rectum in described valve body, described latus rectum includes that water inlet and outlet, described valve seat are located at
Water inlet, the junction of described water inlet and valve seat is respectively equipped with cooperate interior to ladder with extroversion ladder, described
Interior use interference fit to ladder and export-oriented ladder, be provided with reinforcement in described valve body, described reinforcement connects to be had
Elastic component, it is spherical flap that one end connection of described elastic component has flap, described flap, described flap and valve seat
The first sealing ring it is provided with at sealing.
Further, described interior it is provided with the second sealing ring, the second described sealing ring between ladder and export-oriented ladder
For round rubber sealing ring.
Further, the first described sealing ring is through vulcanizing treatment and to have angled rubber seal, described
Angle is 100 ° ~ 150 °.
Further, described reinforcement is the six roots of sensation.
Further, described valve body and valve seat are the most circular.
The beneficial effects of the utility model are: owing to taking technique scheme, and this wafer type full-bore soft seal is waterproof
Hitting check valve seal performance good, negotiability is strong, and flap design is spherical shape, can be with the disperse medium perpendicular acting to flap
Power, thus it is thinned flap thickness, saving material, spherical shape facilitates current to pass through, thus it also avoid water hammer, tool
Have with low cost, practical and convenient, it is easy to the advantages such as popularization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 reinforcement 8 structural representation.
In figure 1, valve body；2, valve seat；3, latus rectum；4, water inlet；5, outlet；6, interior to ladder；7, export-oriented ladder；8, add
Strong muscle；9, elastic component；10, flap；11, the first sealing ring；12, the second sealing ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of wafer type full-bore soft seal water impact preventing check-valves, including valve body 1 and valve seat 2,
Offering latus rectum 3 in described valve body 1, described latus rectum 3 includes that water inlet 4 and outlet 5, described valve seat 2 are located at into water
At mouthfuls 4, described water inlet 4 and the junction of valve seat 2 are respectively equipped with cooperate interior to ladder 6 with extroversion ladder 7, described
Interior use interference fit to ladder 6 and export-oriented ladder 7, be provided with reinforcement 8 in described valve body 1, described reinforcement 8 connect
Being connected to elastic component 9, one end of described elastic component 9 connects flap 10, and described flap 10 is spherical flap, described valve
Lobe 10 is provided with the first sealing ring 11 at the sealing of valve seat 2.Flap 10 is designed as spherical, can be with disperse medium to flap 10
Vertical, the most just can save raw material with the thickness of thinning flap 10, reduce cost, the flap 10 of spherical
Facilitate current to circulate, thus it also avoid water hammer.
Preferably, described is interior to being provided with the second sealing ring 12 between ladder 6 and export-oriented ladder 7, the second described sealing
Circle 12 is round rubber sealing ring.Second sealing ring 12 can improve the sealing of check-valves further.
Preferably, the first described sealing ring 11 is through vulcanizing treatment and to have angled rubber seal, described
Angle is 100 ° ~ 150 °.At valve seat 2 and flap 10 sealing, sulfuration has the first sealing ring 11 of an angle, has certain angle
First sealing ring 11 uses by the way of contact of line to face with spherical flap, thus reaches absolute zero leakage, and soft seal
Noise can also be reduced.
Preferably, described reinforcement 8 is the six roots of sensation；Described valve body 1 and valve seat 2 are the most circular.Reinforcement 8 can improve
The bulk strength of check-valves, valve body 1 and valve seat 2 inner flow passage use sulfuration process design, will not be washed away by medium, only improve
Return the service life of valve.
It is valve seat 2 nominal bore diameter that the combination of valve body 1 and flap 10 is computed meeting five runners of full-bore, i.e. runner one；
Runner two is the ring-like area that flap 10 Lift becomes with hole rows in valve seat 2；Runner three is that valve body 1 internal diameter is with flap 10 external diameter
Between spacer ring profile amass；Runner four flows out the intersection area of valve body 1 for medium；Runner five flows out valve body 1 for medium
Rear runner.Five flow areas are all higher than or are equal to the flow area of pipeline nominal such that it is able to improve the circulation of check-valves
Ability, decrease flow resistance.
The when of use, medium is intake at water inlet 4, under the pressure effect of medium, backs down flap 10, at check-valves
In open mode, medium is discharged from outlet 5.After medium is drained, upstream pressure, close to zero, relies on working media after valve
Pressure makes flap 10 compress valve seat 10, coordinates angled first sealing ring 11, reaches sealing effectiveness, closes valve, so, only
Return valve just can work the most circularly.
This wafer type full-bore soft seal water impact preventing check valve seal performance is good, and negotiability is strong, and flap design is sphere
Shape, with the disperse medium vertical to flap, thus can be thinned flap thickness, save material, spherical shape side
Informal water stream passes through, thus it also avoid water hammer, has with low cost, practical and convenient, it is easy to the advantages such as popularization.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention, but this
The invention thought of utility model is not limited to that utility model, the repacking of any utilization inventive concept, all will include this in specially
In profit scope of patent protection.
