Detailed description of the invention
Below in conjunction with detailed description of the invention and Figure of description, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Detailed description of the invention 1
Refer to Fig. 1, a kind of one-way relief valves, including valve shell 1, inlet channel 12, outlet passageway 2, piston 3 and elastic component 4, inlet channel 12 and outlet passageway 2 may be contained within valve shell 1, and valve shell 1 is internally provided with chamber 11, and outlet passageway 2 connects with chamber 11, piston 3 is arranged in chamber 11, piston 3 is applied pressure by elastic component 4 so that piston 3 closes inlet channel 12, is provided with gas cleaning plant 21 in inlet channel 12.Gas cleaning plant 21 is set to activated carbon, and air cleaning can be played good effect by activated carbon.Elastic component 4 is set to spring, because spring belongs to general elastic component, low cost of manufacture, result of use are good.
Preferably, valve shell 1 also includes sealing plate 5, and sealing plate 5 is arranged on the top of piston 3.Piston 3 includes contact site 31 and the movable part 32 connected as one with contact site 31, and elastic component 4 is sheathed on movable part 32, and one end of elastic component 4 props up sealing plate 5, and the other end of elastic component 4 props up contact site 31.The inwall of valve shell 1 is provided with step 13, step 13 contacts with contact site 31 cooperation, when contact site 31 moves up and does not contact with step 13 so that the connection of inlet channel 12 and outlet passageway 2, and then discharge the intrinsic pressure of the product that is connected with one-way relief valves.
Preferably, the thickness sum h of contact site 31 and movable part 32 less than the chamber of chamber 11 from d so that movable part 32 can move up and down in chamber 11.It addition, piston 3 total is set to "T"-shaped structure by present embodiment, what be so conducive to elastic component 4 installs the realization with operation principle of the present utility model.
Detailed description of the invention 2
Refer to Fig. 2, with detailed description of the invention 1 the difference is that: the piston 3 of present embodiment includes contact site 31, movable part 32 and extension 33, extension 33 is connected with contact site 31 by movable part 32, sealing plate 5 is provided with and stretches out hole 51, extension 33 stretches out in and stretches out hole 51, elastic component 4 is sheathed on movable part 32, and one end of elastic component 4 props up sealing plate 5, and the other end of elastic component 4 props up contact site 31.The surface configuration of extension 33 has scale (not shown), this scale the amount of movement that can observe extension 33 is set, the pressure of interiors of products can be monitored by observing the scale of extension 33.The calculating of extension 33 amount of movement can also adopt the aid such as laser displacement sensor or other sensors to calculate, thus improving the precision that extension 33 amount of movement calculates.
The gas cleaning plant 21 of present embodiment is set to filter cotton or adsorbed film, all can play the air purification effect the same with activated carbon.Elastic component 4 is set to rubber, because rubber also has certain contractile function, it is possible to play the effect the same with spring.Furthermore it is also possible to piston 3 and elastic component 4 to be made of one the rubber stopper (that is: remove elastic component 4, piston 3 is directly changed elastomeric material) of structure, equally possible play the effect that " piston 3+ elastic component 4 " combines.
