Fig. 4:For the structural schematic diagram of the embodiment of the present invention 2.
Specific implementation mode
The invention is further explained in the following combination with the attached drawings of the specification
Embodiment 1:A kind of unidirectional relief valve as shown in Fig. 1 ~ 3, which is characterized in that by straight connector valve body 1, ball sealer 2 and bullet Property elastic 3 form.Wherein:
3 one end fixed connection and sealing ball 2 of elastic elastic;1 inner wall of straight connector valve body be equipped with 2 matched valve seat 11 of ball sealer, it is close Blocking 2 is limited to the side of valve seat 11, and barb is equipped on 1 inner wall of straight connector valve body of the valve seat other side opposite with ball sealer 2 12.The supporting rod 13 for being tensioned elastic elastic 3 is equipped in straight connector valve body 1 between barb 12 and valve seat 11.Elastic elastic 3 The other end be equipped with hitch for being inserted in barb 12;In 11 other side of valve seat, elastic elastic 3 is tensioned by supporting rod 13, with So that 2 elastic packing of ball sealer is pressed in 11 side of above-mentioned valve seat.
Further, the above-mentioned supporting rod 13 for being tensioned elastic elastic 3 is adjustable to stretch 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 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, supporting rod 13 are also two, when When above-mentioned elasticity elastic 3 is broken, it can adjust supporting rod 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 elasticity elastic 3, which is three, can also can be repaired when being broken.
For the ease of quickly installing ball sealer, the above-mentioned hitch for being inserted in barb 12 can be by hooking tool 5, will It is inserted in barb 12.
In order to ensure elastic elastic 3 in fluctuation, in use, and when adjustment do not fall off the end of supporting rod, influence Support effect, so the end of above-mentioned supporting 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 is broken, can by adjust with still Adjustable knob 14 that can be on the supporting 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, the position of adjust automatically ball sealer to make 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.
Installation method:First sealing ring 3 is put into from the right side of valve body 1 at limiting section 11, then puts ball sealer 2 Enter, tool is recycled to hook two spring ropes 21 to barb 12 from the left side of valve body 1.
Its operation principle:In stationary state, ball 2 can be caused it to be close to valve by the traction or so of elastic elastic 3 Seat 11 and sealing ring do not simply fail to close by what is formed between valve seat 11 and ball 2 when right side has flow to come in its figure Line is sealed, connection between ball 2 and valve seat 11 can be forced instead more closely, only when left side has flow 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 far 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 not to be defined to 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 domain of the present patent application patent.
