As an embodiment of the invention, a supporting groove is formed in the blocking ball 17, a supporting block 38 is arranged in the supporting groove, slots are symmetrically formed in one end of the blocking ball 17 close to the flow limiting groove 15, push rods 39 are symmetrically and fixedly connected to the inner wall of the flow limiting groove 15, and free ends of the push rods 39 respectively penetrate through the slots and are attached to the side walls of the supporting block 38; during operation, when the pressure inside the cavity 6 is too high, the acting force of the air pressure inside the cavity 6 on the sealing ball 17 is large at the moment, so that the openings of the sealing ball 17 and the flow limiting groove 15 are easily damaged due to the fact that the single-point pressing force is too large, at the moment, the supporting block 38 is arranged inside the sealing ball 17, the ejector rod 39 can indirectly support the sealing ball 17 by applying the acting force to the supporting block 38, the single-point pressing force between the sealing ball 17 and the flow limiting groove 15 is converted into the pressing force between the side wall of the sealing groove and the sealing ball 17, the stress area of the sealing ball 17 is effectively increased, damage to the sealing ball 17 due to stress concentration is reduced, meanwhile, the ejector rod 39 in sliding connection with the inserting groove can also play a role in positioning for the movement of the sealing ball 17, and the stability and effectiveness of the sealing ball 17 during operation are improved.
When the base layer 2 is expanded with heat, the end part of the base layer 2 can apply pressure to the rubber block 5, the elastic rubber block 5 and the compressed cavity 6 can generate certain deformation, and the acting force applied to the base layer 2 is buffered, so that the extrusion damage of the base layer 2 and the wall columns 4 at the end part during expansion with heat and contraction with cold is effectively reduced; when the base layer 2 extrudes the rubber block 5 too much, the air pressure in the cavity 6 is gradually increased at the moment, so that the first piston 12 drives the sliding plate 10 to move towards the inside of the sliding groove 13 at the top end gradually under the action of the air pressure in the cavity 6 until the through groove 11 on the sliding plate 10 moves to the position communicated with the first air passage 8, at the moment, the air in the cavity 6 can flow out and be decompressed through the communicated first air passage 8, the damage or poor buffering effect caused by the overlarge air pressure in the rubber block 5 is effectively reduced, after the pressure in the cavity 6 is gradually reduced, the sliding plate 10 is reset under the action of the compressed first spring 14, so that the through groove 11 is disconnected from the first air passage 8 and is not communicated, the cavity 6 is in a closed state again, the subsequent expansion of the base layer 2 can be effectively buffered, and when the base layer 2 is shrunk, along with the inside pressure reduction of cavity 6 this moment, outside gas can be through pushing up blocking ball 17 from the current-limiting groove 15 this moment and flow into inside cavity 6 to make the gas in cavity 6 can carry out effectual replenishment, guarantee going on that subsequent work of block rubber 5 can stably last, thereby improved the life of block rubber 5 greatly and to the buffer effect of basic unit 2, reduce concrete basic unit 2 and lead to the emery terrace to take place the condition of fracture harm because of expend with heat and contract with cold.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
