Detailed Description

The present invention will be described in more detail with reference to the following examples, which are illustrated in the accompanying drawings. This example is merely a description of the best mode of carrying out the invention and is not intended to limit the scope of the invention in any way.

As shown in fig. 1 to 5, a waterproof vent valve comprises a main valve body 1, and a valve cover 11 and a sealing nut 12 which are respectively in threaded connection with two ends of the main valve body 1, wherein the main valve body 1 sequentially comprises a lower thread section 2, a clamping part 3, an upper thread section 4 and a screwing section 5 from bottom to top, the main valve body 1 is hollow inside, a step hole 31 which is directly communicated with the inner wall of the main valve body 1 is arranged on the periphery of the clamping part 3, an annular pipe 6 and a waterproof vent membrane 61 are connected and fixed in the step hole 31, an auxiliary cover 7 and a combined cover 8 which are mutually buckled are arranged on the periphery of the annular pipe 6, a vent pipe 62 is connected and fixed on one end of the annular pipe 6 which is far away from the step hole 31, evenly distributed shunting holes 63 are arranged on the periphery of the annular pipe 6 which is close to the combined cover 8, an annular groove 71 which is in contact with the periphery of the annular pipe 6 is arranged on one end of the auxiliary, a gap is arranged between the shunting groove 81 and the annular pipe 6, water falling holes 82 which are uniformly distributed are arranged in the shunting groove 81, and an annular bulge 83 is arranged at the edge of one end, far away from the annular pipe 6, of the shunting hole 63. When the valve cover 11 is in threaded connection with the upper threaded section 4, the pressing pieces 52 are pressed by the interior of the valve cover 11, so that the adjacent pressing pieces 52 are attached and extruded with each other, the locking pipe 51 is tightened and firmly attached to the connected parts, and a sealing effect is achieved; the sealing nut 12 is screwed to press the sealing ring 21 to play a role in sealing, and the pressing pipe is made of rubber.

The screwing section 5 comprises a locking pipe 51 fixedly connected with the upper thread section 4 and pressing pieces 52 uniformly distributed around the periphery of the locking pipe 51, and the pressing pieces 52 are matched with the inner wall of the valve cover 11.

A sealing ring 21 sleeved on the periphery of the lower thread section 2 is arranged between the clamping part 3 and the sealing nut 12.

The axis of the vent pipe 62 is arranged parallel to the axis of the main valve body 1.

One end of the auxiliary cover 7 close to the combined cover 8 is provided with clamping columns 72 which are uniformly distributed. The clamping column 72 is used for clamping connection after the auxiliary cover 7 is buckled with the combined cover 8.

The specific working principle is as follows:

when the main valve body 1 is in a working state, external liquid drops down when passing through the vent pipe 62, even if a small amount of liquid enters the annular pipe 6, the liquid also flows into the diversion groove 81 along the diversion hole 63 and drops out through the guide of the water falling hole 82 and the annular protrusion 83, and thus, the liquid can be effectively prevented from being sucked when the pressure in the main valve body 1 is too low and the balance pressure of the external air is absorbed.

Since the technical scheme is used, a waterproof breather valve filters liquid through setting up the effectual filtration of toroidal tube 6, avoids liquid to plug up waterproof ventilated membrane 61, the utility model discloses simple structure, simple to operate has effectually solved the difficult problem that liquid plugged up waterproof ventilated membrane.
