Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Referring to fig. 1 to 5, a dustproof and waterproof pressure-relief explosion venting device comprises a housing 100, wherein a baffle 101 and a sealing plate 103 provided with a through hole are arranged inside the housing 100, the baffle 101 is rotatably connected with the housing 100 through a rotating shaft, and the edge of the sealing plate 103 is hermetically connected with the interior of the housing 100. The sealing plate 103 is connected with a first sealing element 110 in a sealing way on one side close to the baffle 101, and the first sealing element 110 is positioned at the edge of the through hole. The side of the baffle 101 adjacent to the sealing plate 103 is sealingly provided with a second seal 130. The first sealing member 110 and the second sealing member 130 are both annular structures, and the first sealing member 110 and the second sealing member 130 are both made of rubber materials. When the shutter 101 is closed, one end of the first seal 110 away from the sealing plate 103 is located inside or outside the second seal 130, the end of the first seal 110 abuts against the shutter 101, and the end of the second seal 130 abuts against the sealing plate 103.
When the first seal 110 and the second seal 130 intersect, there are two positional relationships between the first seal 110 and the second seal 130. First, there is a gap between the first seal 110 and the second seal 130. Referring to fig. 5, a first sealing member 110 is abutted against the baffle plate 101 to form a first sealing layer, a second sealing member 130 is abutted against the baffle plate 101 to form a second sealing layer, and a sealing space is formed between the first sealing layer and the second sealing layer, so that double-layer sealing of the space between the baffle plate 101 and the sealing plate 103 is realized, and sealing performance is enhanced. With the above arrangement, when there is a gap between the first seal 110 and the baffle 101 or the sealing plate 103, the second seal 130 keeps the baffle 101 and the sealing plate 103 in a sealed state. Because the second sealing layer is intact, liquid cannot enter the sealing space from the gap under the action of pressure in the sealing space, and therefore the second sealing layer cannot be corroded.
The second positional relationship is that the first seal 110 and the second seal 130 are in interference connection. When the first sealing member 110 and the second sealing member 130 are in interference connection, the contact area of the first sealing member 110 and the second sealing member 130 can be increased, and the first sealing member 110 and the second sealing member 130 are mutually extruded through the elasticity of the first sealing member 110 and the second sealing member 130, so that the gap between the first sealing member 110 and the second sealing member 130 is sealed, the tightness of the baffle 101 and the sealing plate 103 is further enhanced, and external fluid and dust are prevented from entering the inner space through the through hole.
Preferably, a groove 111 is provided at an end of the first sealing member 110 away from the second sealing member 130, a mounting ring 105 is provided at an edge of the through hole, the mounting ring 105 is located in the groove 111 and is connected with a side wall of the groove 111 in a sealing manner, and in this embodiment, the side wall of the groove 111 is adhered to the side wall of the mounting ring 105.
Referring to fig. 3, the cross-sectional shape of the first sealing member 110 is isosceles trapezoid, that is, the thickness of the end of the first sealing member 110 near the second sealing member 130 is smaller than the thickness of the end of the first sealing member 110 far from the second sealing member 130. When the first sealing member 110 extends into the second sealing member 130, the end portion of the first sealing member 110, which is close to the second sealing member 130, is not in contact with the second sealing member 130, so that the first sealing member 110 is prevented from abutting against the second sealing member 130 in the rotation process of the baffle 101, and the baffle 101 cannot be normally closed. When the end of the first seal member 110 extends into the second seal member 130, the first seal member 110 and the second seal member 130 abut against each other, and are pressed against each other as the shutter 101 is closed.
Referring to fig. 4, preferably, a third sealing member 131 is disposed in the inner hole of the second sealing member 130, and one end of the third sealing member 131 is adhered to the sidewall of the baffle plate 101. The peripheral wall of the third seal 131 cooperates with the inner bore wall of the second seal 130 to form an annular seal groove 133, the annular seal groove 133 for receiving the first seal 110. When the first seal 110 is located in the annular seal groove 133, the outer peripheral wall and the inner hole wall of the first seal 110 are both abutted against the groove wall of the annular seal groove 133, that is, the groove wall of the annular seal groove 133 and the outer peripheral wall of the third seal 131 are pressed together against the first seal 110, and by providing the third seal 131, the sealing area is increased, so that the sealing performance of the first seal 110 and the second seal 130 is enhanced. In addition, when the second seal member 130 is pressed by the first seal member 110 and tends to move away from the second seal member 130, the third seal member 131 can give the first seal member 110 a force close to the second seal member 130, thereby increasing the pressing force between the first seal member 110 and the second seal member 130 and further enhancing the sealing performance between the first seal member 110 and the second seal member 130.
Preferably, the third sealing member 131 is a cylinder or an air sealing ring made of rubber. The air seal is prior art and will not be described in detail here. When the worker regularly maintains, the air pressure of the air seal ring is checked, and air is supplied to the air seal ring, so that the tightness between the third seal member 131 and the second seal member 130 can be ensured. When the third sealing member 131 adopts the air sealing ring, in the closing process of the baffle 101, the upper portion of the second sealing member 130 is contacted with the peripheral wall of the air sealing ring, along with the closing of the baffle 101, the contact area is larger and larger, and the air sealing ring is easier to squeeze and deform, so that the closing of the baffle 101 is easier, along with the increase of the contact area, the squeezing degree between the air sealing ring and the second sealing member 130 is stronger and stronger, and therefore, the baffle 101 is easier to close, and the tightness between the air sealing ring and the second sealing member 130 is ensured.
Preferably, the inner hole wall of the second sealing member 130 is provided with a containing groove 132, a sealing ring 134 is arranged in the containing groove 132, the section diameter value of the sealing ring 134 is larger than the depth value of the containing groove 132, namely, part of the sealing ring 134 is positioned outside the containing groove 132, and when the first sealing member 110 is positioned in the annular sealing groove 133, the end side wall of the first sealing member 110 is abutted with the peripheral wall of the sealing ring 134 to fill a gap between the first sealing member 110 and the second sealing member 130. It should be noted that the seal ring 134 is only applicable to the case where the first seal member 110 and the second seal member 130 are in interference connection.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
