Below with reference to embodiment shown in the drawings the utility model is described in detail.But these mode of executions do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in the protection domain of the present utility model.
Consult Fig. 1 to Fig. 2, check valve 10 of the present utility model mainly includes body 20 and hollow elasticity body 30.
As shown in Figure 2, described body 20 is made up of water inlet housing 21 and water outlet housing 23.Wherein, described water inlet housing 21 has into water 211, tank 213, intake tunnel 215 and flange 217; Described drainage channel 215 is communicated with described tank 213 and described water inlet 211, and have be positioned at described room 25 open 216; The external diameter of described tank 213 is greater than described water intake 211, and has with described and open the interior diapire 218 that 216 ora terminalis flush; 217 of described flanges are surrounded on described tank 213.Secondly, described water outlet housing 23 have that water outlet 231, ring-type are outstanding 233, intake tunnel 235 and flange 237; Described intake tunnel 235 is communicated with described ring-type outstanding 233 and described water outlet 231, and have be positioned at described room 25 open 236; Described ring-type outstanding 233 has with described opens the end 238 that 236 ora terminalis flush; 237 of described flanges are surrounded on described ring-type outstanding 233.In addition, the outer circumferential face of the outer circumferential face of described water inlet housing 21 and described water outlet housing 23 is respectively arranged with snap ring portion 22,24, and so as to making water pipe T1, T2 can firmly be socketed on the outer circumferential face of described water inlet housing 21 and the outer circumferential face of described water outlet housing 23.
During assembling, as shown in Figure 3, the ring-type of described water outlet housing 23 outstanding 233 embeds in the tank 213 of described water inlet housing 21, makes the flange 217 of described water inlet housing 21 be fixed in the flange 237 of described water outlet housing 23.Described flange 217 is fixed in the mode of described flange 237, see through (but being not limited to) and on described flange 217, form fusion piece 219 around the notch of described tank 213, after described ring-type outstanding 233 embeds in the described tank 213, described water inlet housing 21 of fast rotational and water outlet housing 23 make described flange 217 be fused to described flange 237 so as to the mode of utilizing frictional heat.After described water inlet housing 21 and described water outlet housing 23 are affixed, its inner room 25 that forms, described discharge water W can enter described room 25 by described water inlet 211 and be discharged by described water outlet 231.
Please consult Fig. 2 again, described hollow elasticity body 30 has head 31, body portion 33, end 35 and is communicated with described head 31, body portion 33 and end 35 in present embodiment chamber 37.Described head 31 extends the former of institute by described body portion 33 bodies towards outer ring-like in this example; Described end 35 is made of from the limb 351 that described body portion 33 bodies extend respectively (but being not limited to) two, and, as shown in Figure 2, the end 353 of described two limbs 351 has part to be abutted against mutually under normality and has part affixed mutually, and forms otch 355.As shown in Figure 4, described two limb 351 elastically deformables are opened described otch 355, and as shown in Figure 3, but described two limbs, 351 elasticity involutions make described otch 355 closures.
When assembling check valve 10 of the present utility model, head 31 with described hollow elasticity body 30 is placed in the described tank 213 earlier, make the ring-type outstanding 233 of described water outlet housing 23 embed in the described tank 213 again and make its end 238 be tight against described head 31, and with described head 31 be anchored on described terminal 238 and described between the diapire 218, at this moment, the body portion 33 of described hollow elasticity body 30 and end 35 are located in the described water outlet housing 23, afterwards, utilize affixed described water inlet housing 21 of foregoing mode and water outlet housing 23, described hollow elasticity body 30 is arranged in the room 25 of described body 20.
During actual the use, as shown in Figure 4, check valve 10 of the present utility model connects the water pipe T1 of aircondition (not shown) and is sheathed on described water inlet housing 21 and described water outlet housing 23 respectively in order to the water pipe T2 that discharge water is drained into the collecting annulus (not shown) in order to be installed in the discharge pipe line (not shown).When the discharge water W that discharges from aircondition continues to flow in the described chamber 37 and during generation hydraulic pressure through described intake tunnel 215 from described water intake 211, described end 35 is understood resiliently deformables and described otch 355 is opened, at this moment, described chamber 37 can be connected with described body water outlet 231, make discharge water W from described chamber 37 through described exhalant canal 235 and in described water outlet 231 flow to described water pipe T2; On the contrary, as shown in Figure 3, in discharge water W stops to flow into described chamber 37, when causing hydraulic pressure to disappear, described end 35 is understood the elasticity involutions and is made described otch 355 closures, and at this moment, described chamber 37 can't be connected with described body water outlet 231, in order to do the discharge water W that residues in the described exhalant canal 235 can be back in the described chamber 37, be back in the described intake tunnel 215 to avoid discharge water.
Because the end 35 of check valve 10 of the present utility model can be according to having or not hydraulic pressure and resiliently deformable in the chamber 37, and then control described otch 355 closure or openness, therefore can not be subjected to gravitational restriction, compared to against current valve commonly used, the utility model can be installed on the discharge pipe line of various configuration trends, so suitability is preferable, practicability is more extensive.In addition, because the head 31 of described hollow elasticity body 30 is pushed against between the interior diapire 218 of the end 238 that is fixed in described ring-type outstanding 233 and described tank 213, described hollow elasticity body 30 can firmly be arranged in the described body room 25, and can avoid the discharge water in the described exhalant canal 235 to leak out in the described intake tunnel 215.
The detailed description of above listed row only is specifying at feasibility mode of execution of the present utility model; they are not in order to limiting protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit done and all should be included within the protection domain of the present utility model.
