Specific embodiment
With reference to Figure of description, the invention will be further described
Embodiment 1：A kind of unidirectional relief valve as shown in Figures 1 to 3, it is characterised in that by straight connector valve body 1, ball sealer 2
Constitute with elastic elastic 3.Wherein：
One end fixed connection and sealing ball 2 of elastic 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 contrary with ball sealer 2
Barb 12.The support bar 13 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 inserted in barb 12；In the opposite side of valve seat 11, elastic elastic 3 passes through support bar 13
Tightly, so that the elastic packing of ball sealer 2 is pressed in the side of above-mentioned valve seat 11.
Further, the above-mentioned support bar 13 for being 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, not can be located at valve seat 11 and sealing
Between ball, will otherwise gap, affect sealing effectiveness, so the fixed bit of above-mentioned many elastic one end of elastic 3 and ball sealer 2
Setting in the opposite side of seal line.
In order to preferably connect, while avoiding repeating connection and invalid connection, above-mentioned barb 12, elastic elastic 3, support
The quantity of bar 13 is consistent and is mutually paired.It is also two that above-mentioned elastic elastic 3 is two, i.e. barb 12, support bar 13, when
When above-mentioned elastic elastic 3 ruptures, support bar 13 can be adjusted by adjustable knob 14, tighten residual elasticity elastic 3, make list
Continue normally to use to relief valve.It is also the same that above-mentioned elastic elastic 3 is three, it is also possible to can be repaired when rupturing.
For the ease of quickly installing ball sealer, the above-mentioned hitch for being inserted in barb 12 can be by hook instrument 5, will
It is inserted in barb 12.
In order to ensure elastic elastic 3 in fluctuation, when using, and it is not fall off the end of support bar, affecting during adjustment
Support effect, so the end of above-mentioned support bar 13 is provided with Y shape groove 16, for the elastic elastic 3 placed, stably tighten.
As shown in figure 3, when the elastic elastic 3 in unidirectional relief valve wherein ruptures, can by adjust with still
The adjustable knob 14 on support bar 13 that root elasticity elastic 3 that can normally use is matched tightening elastic elastic 3, elasticity
Elastic 3 will drive ball sealer, the position of adjust automatically ball sealer so as to can normally 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 by sealing ring 3 from the right side of valve body 1, it is put at limiting section 11, 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 resting state, ball 2 can be subject to traction of elastic elastic 3 or so, cause it to be close to valve
Seat 11 and sealing ring, when right side has current to come in its figure, do not simply fail to close by what is formed between valve seat 11 and ball 2
Envelope line, can force on the contrary the connection between ball 2 and valve seat 11 more tight, only when left side has current to come in figure,
The seal line formed between valve seat 11 and ball 2 just can be rushed to open, but ball can still receive drawing for elastic elastic 3, no
Can be too remote from valve seat 11, when the water flow stops, then drawing for elastic elastic 3 can be received again, valve seat 11 is close to again, formed and sealed
Line.
Above-mentioned above is only, to presently preferred embodiments of the present invention, not the scope of the present invention to be defined, therefore is not being taken off
On the premise of design spirit of the present invention, this area ordinary skill technical staff construction above-mentioned to the present invention, feature and principle
The equivalence changes made or decoration, all should fall in the protection domain of the present patent application patent.
