Embodiment
With reference to Figure of description, the utility model is described in further detail
Embodiment 1：Unidirectional relief valve as shown in Figures 1 to 3, it is characterised in that by straight connector valve body 1, ball sealer 2 and bullet
Property elastic 3 forms.Wherein：
The elastic one end fixed connection and sealing ball 2 of elastic 3；The inwall of straight connector valve body 1 is provided with the valve seat matched with ball sealer 2
11, ball sealer 2 is limited to the side of valve seat 11, is provided with the inwall of straight connector valve body 1 of the valve seat opposite side opposite with ball sealer 2
Barb 12.The support bar 13 for being used for being tensioned elastic elastic 3 is provided with straight connector valve body 1 between barb 12 and valve seat 11.Elasticity
The other end of elastic 3 is provided with the hitch for being used for being inserted in barb 12；In the opposite side of valve seat 11, elastic elastic 3 is opened by support bar 13
Tightly, to cause the elastic packing of ball sealer 2 to be pressed in the above-mentioned side of valve seat 11.
Further, the above-mentioned support bar 13 for being used to be tensioned elastic elastic 3 is adjustable to stretch into the axle center stroke of straight connector valve body 1
Threaded support bar, its top be provided with adjustable knob 14.
In order to more preferably reach better seal effect, above-mentioned valve seat 11 is made up of annular stop portion and sealing ring, annular limit
The internal diameter in position portion is less than the sphere diameter of ball sealer 2；Sealing ring is fixed on the interior edge of above-mentioned annular stop portion side；During sealing, ball sealer 2
Seal line is formed with above-mentioned sealing ring.
In order to ensure normal sealing effectiveness, elastic elastic must be positioned in seal line, can not be located at valve seat 11 and sealing
Between ball, it otherwise will gap, and influence sealing effectiveness, so above-mentioned more elastic one end of elastic 3 and the fixed bit of ball sealer 2
Setting in the opposite side of seal line.
In order to preferably connect, while avoid repeating connection and invalid connection, above-mentioned barb 12, elastic elastic 3, support
The quantity of bar 13 is consistent and is mutually paired.Above-mentioned elastic elastic 3 is two, i.e., barb 12, support bar 13 are also two, when
When above-mentioned elastic elastic 3 is broken, it can adjust support bar 13 by adjustable knob 14, tighten residual elasticity elastic 3, make list
Continue normal use to relief valve.It is also the same that above-mentioned elastic elastic 3, which is three, can also can be repaired when being broken.
For the ease of quickly installation ball sealer, the above-mentioned hitch for being used to be inserted in barb 12 can be by hooking instrument 5, will
It is inserted in barb 12.
In order to ensure elastic elastic 3 in fluctuation, in use, and do not fall off the end of support bar during adjustment, influence
Support effect, so the end of above-mentioned support bar 13 is provided with Y shape groove 16, the elastic elastic 3 for placing, stably tightened.
As shown in figure 3, when the elastic elastic 3 in unidirectional relief valve wherein one is broken, can by regulation with still
Adjustable knob 14 that can be on the support bar 13 that is matched of that root elasticity elastic 3 of normal use, to tighten elastic elastic 3, elasticity
Elastic 3 will drive ball sealer, the position of adjust automatically ball sealer, make it can normal use.
Side as described above is the right side in accompanying drawing, and opposite side is the left side in accompanying drawing.
Installation method：First sealing ring 3 is put at limiting section 11 from the right side of valve body 1, then puts ball sealer 2
Enter, recycling instrument hooks two spring ropes 21 to barb 12 from the left side of valve body 1.
Its operation principle：In inactive state, ball 2 can be caused it to be close to valve by traction of elastic elastic 3 or so
Seat 11 and sealing ring, when right side there are current to come in its figure, do not simply fail to close by what is formed between valve seat 11 and ball 2
Line is sealed, can force the connection between ball 2 and valve seat 11 more close on the contrary, only when left side has current to come in figure,
The seal line formed between valve seat 11 and ball 2 can be just rushed to open, but ball still can be by the traction of elastic elastic 3, no
Can be too remote from valve seat 11, when the water flow stops, then it can be close to valve seat 11 again by the traction of elastic elastic 3 again, form sealing
Line.
Above-mentioned above is only to preferred embodiment of the present utility model, and not the scope of the utility model is defined,
Therefore on the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff is above-mentioned to the utility model
The equivalence changes or decoration that construction, feature and principle are made, all should fall into the protection domain of present utility model application patent.
