Specific embodiment
The invention is further explained in the following combination with the attached drawings of the specification
A kind of embodiment 1: unidirectional relief valve as shown in Fig. 1 ~ 3, which is characterized in that by straight connector valve body 1, ball sealer 2
It is formed with elastic elastic 3.Wherein:
Elastic 3 one end fixed connection and sealing ball 2 of elastic；1 inner wall of straight connector valve body is equipped with and the matched valve seat of ball sealer 2
11, ball sealer 2 is limited to the side of valve seat 11, is equipped on 1 inner wall of straight connector valve body of the valve seat other side opposite with ball sealer 2
Barb 12.The support rod 13 for being tensioned elastic elastic 3 is equipped in straight connector valve body 1 between barb 12 and valve seat 11.Elasticity
The other end of elastic 3 is equipped with the hitch for being inserted in barb 12；In 11 other side of valve seat, elastic elastic 3 is opened by support rod 13
Tightly, so that 2 elastic packing of ball sealer is pressed in above-mentioned 11 side of valve seat.
Further, the above-mentioned support rod 13 for being tensioned elastic elastic 3 is adjustable to protrude into 1 axle center stroke of straight connector valve body
Threaded support bar, top be equipped with adjustable knob 14.
In order to more preferably reach better seal effect, above-mentioned valve seat 11 is made of annular stop portion and sealing ring, annular limit
The internal diameter in position portion is less than 2 sphere diameter of ball sealer；Sealing ring is fixed on the interior edge of above-mentioned annular stop portion side；When sealing, ball sealer 2
Seal line is formed with above-mentioned sealing ring.
In order to ensure normal sealing effect, elastic elastic be 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 effect, so the fixed bit of above-mentioned more elastic elastics 3 one end and ball sealer 2
Setting in the other side of seal line.
It in order to preferably connect, while avoiding repeating to connect and connecting in vain, above-mentioned barb 12, elastic elastic 3, support
The quantity of bar 13 is consistent and is mutually paired.Above-mentioned elasticity elastic 3 is two, i.e., barb 12, support rod 13 are also two, when
When above-mentioned elasticity elastic 3 is broken, support rod 13 can be adjusted, residual elasticity elastic 3 is tightened, makes list by adjustable knob 14
Continue normal use to relief valve.Above-mentioned elasticity elastic 3 be three be also it is the same, can also can be repaired when being broken.
It is above-mentioned for being inserted in the hitch of barb 12 for the ease of quickly installing ball sealer, can be by hook tool 5, it will
It is inserted in barb 12.
In order to guarantee elastic elastic 3 in fluctuation, in use, and when adjustment do not fall off the end of support rod, influence
Support effect, so the end of above-mentioned support rod 13 is equipped with Y shape groove 16, for placing, stablizing the elastic elastic 3 tightened.
As shown in figure 3, when the elastic elastic 3 in unidirectional relief valve wherein one be broken when, can by adjust with still
Can adjustable knob 14 on the support rod 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, and the position of adjust automatically ball sealer makes it can normal use.
Side as described above is the right side in attached drawing, and the other side is the left side in attached drawing.
Sealing ring: being first put at valve seat 11 from the right side of valve body 1, be then put into ball sealer 2 by installation method,
Recycling tool hooks two spring elastics 3 to barb 12 from the left side of valve body 1.
Its working principle: in stationary state, ball sealer 2 will receive the traction or so of elastic elastic 3, it is caused to be close to valve
Seat 11 and sealing ring do not simply fail to close by what is formed between valve seat 11 and ball sealer 2 when right side has water flow to come in its figure
Line is sealed, connection between ball sealer 2 and valve seat 11 can be forced instead more closely, only when left side has water flow to come in figure,
The seal line formed between valve seat 11 and ball sealer 2 can be just rushed to open, but ball sealer 2 still can be by the traction of elastic elastic 3, no
Can be too far from valve seat 11, when the water flow stops, then it can be close to again valve seat 11 by the traction of elastic elastic 3 again, form sealing
Line.
Above-mentioned above is only to be not intended to limit the scope of the present invention to presently preferred embodiments of the present invention, therefore do not taking off
Under the premise of design spirit of the present invention, this field ordinary engineering and technical personnel structure, feature and principle above-mentioned to the present invention
The equivalence changes or decoration made, should all fall into the protection scope of the present patent application patent.
