The components in the figures are numbered as follows: the device comprises a protective cylinder 1, a protective cylinder heat-insulating layer 3, an air intake and exhaust heat-insulating mechanism 4, a supporting plate 401, a guide shaft 402, a fixed heat-insulating layer 403, a movable sleeve 404, a heat-insulating layer supporting plate 405, a movable heat-insulating layer 406, a spring 407 and a limiting sleeve 408.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in fig. 1-2, a combined type intake and exhaust valve heat preservation mechanism, including a protection section of thick bamboo 1 of direct-burried in the soil layer, be equipped with the air valve that is used for controlling the water pipe intake and exhaust in the protection section of thick bamboo, the outer wall parcel of a protection section of thick bamboo 1 has a protection section of thick bamboo heat preservation 3, fixedly connected with intake and exhaust heat preservation mechanism 4 in the protection section of thick bamboo 1, intake and exhaust heat preservation mechanism 4 includes fixed heat preservation 403 with protection section of thick bamboo 1 fixed connection and liftable motion's movable heat preservation 406, certain clearance staggers with fixed heat preservation 403 when intake and exhaust of movable heat preservation 406, with fixed heat preservation 403 sealed cooperation when there is not pressure difference inside and outside protection. The utility model discloses a set up into when exhausting heat preservation mechanism guarantees to advance to exhaust in protecting a section of thick bamboo, the air business turn over can be allowed to the heat preservation, and the heat preservation seals completely when there is not pressure differential inside and outside a protection section of thick bamboo, avoids low temperature air to get into, has improved the heat preservation effect of air valve.
In the above technical solution, the air intake and exhaust heat preservation mechanism 4 further includes an upper layer of support plate 401 and a lower layer of support plate 401 fixedly connected with the protection tube 1, the two layers of support plates 401 are respectively located at the upper end and the lower end of the fixed heat preservation layer 403, and the support plates 401 are fixedly connected through the guide shaft 402. The guide shaft 402 is movably sleeved with a movable sleeve 404, the outer side of the movable sleeve 404 is provided with an insulating layer supporting plate 405 for supporting a movable insulating layer 406, the guide shaft 402 is sleeved with a spring 407 positioned at the lower end of the insulating layer supporting plate 405, and the lower end of the guide shaft 402 is fixedly sleeved with a limiting sleeve 408 which is in limiting and abutting connection with the insulating layer supporting plate 405.
When the air valve does not exhaust or intake air, no pressure difference exists between the inside and the outside of the protective cylinder, and the movable heat-insulating layer is just positioned in the heat-insulating hole of the fixed heat-insulating layer to form a sealing structure so as to completely prevent external low-temperature air from entering; when the air valve exhausts, the pressure in the protective cylinder is greater than the outside pressure, the movable heat-insulating layer moves upwards under the action of pressure difference and staggers a certain gap, and air flows out of the heat-insulating hole; when the air valve admits air, the outer side pressure of the protective cylinder is larger than the inner side pressure, the movable heat-insulating layer moves downwards under the action of pressure difference and staggers a certain gap, and air flows out of the heat-insulating hole.
