Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A trough body for a valve-controlled sealed storage battery is formed as shown in figure 1 and comprises a box body 1 for placing the battery, wherein the top end of the box body 1 is covered with a top cover 2; the top end of the top cover 2 is provided with a through hole 3, and a liquid feeding pipe 4 is connected on the through hole 3; a bifurcated port is formed in the liquid feeding pipe 4, one end of the bifurcated port is connected with a pressure relief pipe 5, and the other end of the bifurcated port is connected with a switch valve 6; and a pressure release valve 7 is arranged on the pressure release pipe 5.
A sealing ring 8 is arranged between the top cover 2 and the box body 1, and the bottom end of the top cover 2 is provided with an annularly arranged hot melt adhesive 9; a sealing ring 10 is connected to the top cover 2 in a hot melting way at a position corresponding to the connection position of the through hole 3 and the liquid feeding pipe 4; the top cover 2 is provided with an opening 11 for extending the positive plate and the negative plate, and the edge of the opening 11 is provided with hot melt resin 12.
The working principle is as follows: a worker puts the battery and the electrode solution into the box body 1 and seals and covers the top cover 2; the hot melt adhesive 9 at the bottom end of the top cover 2 is well adhered to the top of the box body 1 by heating the bottom end of the top cover 2, so that the top cover 2 and the box body 1 are hermetically connected; and the position department of contact between top cap 2 and the box body 1 is provided with sealing washer 8, has further improved the leakproofness between top cap 2 and the box body 1.
