The specific embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1 to Figure 3, the utility model embodiment provides a kind of seal valve, comprises valve body 10, valve gap 20 and waterproof ventilated membrane 30.Valve body 10 comprises body and is arranged at intrinsic capillary channel 11, and capillary channel 11 extends along the axial direction of body.Valve gap 20 is connected with valve body 10, and valve gap 20 is provided with the connecting hole 21 being communicated with atmosphere, and the first end of capillary channel 11 is communicated with connecting hole 21; Waterproof ventilated membrane 30 is arranged between valve body 10 and valve gap 20, and corresponding to the first end setting of capillary channel 11.
What need to say is, the first end of valve body 10 and valve gap 20 are connected, and the first end of the first end of valve body 10 and capillary channel 11 is positioned at homonymy, the second end of valve body 10 arranges away from valve gap 20, and the second end of valve body 10 and the second end of capillary channel 11 are positioned at homonymy.When the pressure of the second end of valve body 10 is normal or fluctuate in little situation, above-mentioned capillary channel can prevent that the liquid of valve body 10 second ends from being flowed out by the first end of valve body 10, thereby plays the effect of throttling sealing.When the pressure of the second end of valve body 10 promotes rapidly or when lifting amplitude is larger, the pressure of this side is greater than the pressure drag of capillary channel 11, makes the gas of valve body 10 second ends can be delivered to by capillary channel 11 first end of valve body 10.
Further, owing to there being the existence of waterproof ventilated membrane 30, after capillary channel 11 reducing pressure by regulating flows, the steam that is conducive to be discharged by the first end of capillary channel 11 is condensed into rapidly liquid water droplets on waterproof ventilated membrane 30, and above-mentioned water droplet is assembled near a side of capillary channel 11 at waterproof ventilated membrane 30.
In the time of the pressure decreased of the second end of valve body 10, because the gas of the existence outside of pressure differential and water droplet that waterproof ventilated membrane 30 1 sides are condensed are inhaled into the second end of valve body 10 again, to guarantee the water content of this end.
As shown in Figure 1, valve body 10 in the utility model embodiment is stepped, comprise large footpath section, path section and be connected large footpath section and the linkage section of path section, valve gap 20 is connected with large footpath section, waterproof ventilated membrane 30 is arranged on linkage section, and containing cavities 12 is surrounded jointly by path section and waterproof ventilated membrane 30.
On valve gap 20, be provided with external thread section, in the section of large footpath, be provided with the internal thread segment coordinating with above-mentioned external screw thread linkage section, above-mentioned valve gap 20 is threaded connection fixing with valve body 10.
Further, in order to guarantee the reliability of sealing, between valve gap 20 and waterproof ventilated membrane 30, be also provided with the first black box 41, above-mentioned the first black box 41 is crimped on waterproof ventilated membrane 30, and in the time of the rigging position of seal valve, coordinate with the end extruding of the external thread section of valve gap 20, to guarantee the sealing reliability of waterproof ventilated membrane 30.
Preferably, above-mentioned valve body 10 also comprises containing cavities 12, is arranged on body, and waterproof ventilated membrane 30 is covered in the first end of containing cavities 12, and capillary channel 11 is connected with the second end of containing cavities 12.Containing cavities 12 is set can be so that the water droplet that condenses of storage waterproof ventilated membrane 30, thereby in the time that valve body 10 second end pressures reduce, the above-mentioned water droplet condensing can reclaim comparatively efficiently and easily.
Further, the bottom of the second end of containing cavities 12 is provided with liquid collecting portion, and above-mentioned capillary channel 11 is connected with liquid collecting portion.Particularly, as shown in Figure 1, the liquid collecting portion in the utility model embodiment is arranged to rounded channels structure.
Liquid collecting portion is arranged to rounded channels structure, because the position of rounded channels is lower, the water droplet condensing is entered in rounded channels under the effect of gravity, in the time there is low pressure in the second end of valve body 10, due to water droplet isolated capillary channel 11 and outside air, so the water droplet in rounded channels can preferentially be recycled to the second end of valve body 10, and then maintain the pressure balance inside and outside seal valve by drawing extraneous part air.
Preferably, above-mentioned capillary channel 11 can be many, circumferentially spaced apart along the body of valve body 10.Many capillary channels 11 are set, can make pressure release, ventilative to wait operation to carry out faster, thereby reach the object of the pressure release of raising seal valve, the efficiency of breathing freely.
It should be noted that, in the utility model embodiment, on valve gap 20, be also provided with the air chamber 22 being connected with connecting hole 21, waterproof ventilated membrane 30 is covered in air chamber 22 one end away from connecting hole 21, be that air chamber 22 is oppositely arranged with containing cavities 12, above-mentioned waterproof ventilated membrane 30 is separated the cut-off rule as the two by above-mentioned two cavitys.
Further, in the utility model embodiment connecting hole 21 be multiple, circumferentially spaced apart along valve gap 20, so that the time of ventilation and exhaust is shorter, improves and takes a breath and the efficiency of exhaust.
The utility model also provides a kind of regenerative apparatus, comprises above-mentioned seal valve.
Particularly, above-mentioned regenerative apparatus comprises heat-accumulator tank, and seal valve is installed on heat-accumulator tank, and is provided with the second black box 42 between the valve body 10 of seal valve and heat-accumulator tank.On the second end of above-mentioned valve body 10, be provided with external screw thread, above-mentioned heat-accumulator tank correspondence position is provided with internal thread, and above-mentioned valve body 10 is fixedly connected with by screw thread with heat-accumulator tank.
Further, the second end of above-mentioned capillary channel 11 and the internal communication of heat-accumulator tank, the pressure of the heat-accumulator tank inside, pressure position of valve body 10 second ends mentioned above.
It should be noted that, the first black box 41 and the second black box 42 in the utility model embodiment are sealing ring.
From above description, can find out, the utility model the above embodiments have realized following technique effect: capillary channel is set, in the time that the pressure of valve body one end of seal valve is normal, capillary channel can play the effect of throttling sealing, in the time that the pressure increasing degree of this end of valve body of seal valve is larger, capillary channel can play the effect of pressure release, waterproof ventilated membrane is set, can stop the liquid turnover of valve body both sides, but can not stop the gas of seal valve and ambient atmosphere to exchange, solve pressure release, sealing, waterproof and ventilative object thereby reach simultaneously.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
