Description

Technical Field

[0001] The invention relates to the technical field of electrode boiler sealing component detection, in particular to an electrode boiler sealing component testing device. Background Art

[0002] An electrode boiler is a device that heats water by converting electrical energy into heat energy through electrodes. Its working principle is based on the ionic conductivity of water. In an electrode boiler, the electrodes are directly inserted into the water. When the electrodes are connected to the power supply, the current passes through the water, and the water acts as a resistor. Due to the thermal effect of the current, the water is heated, thereby producing hot water or steam. Electrode boilers are mostly used in urban central heating systems. Electrode boilers can be used as heat source equipment to provide heating for buildings in the area. Especially in areas with abundant electricity resources and high environmental protection requirements, electrode boilers are used because of their clean and efficient characteristics. During the use of electrode boilers, the seals in electrode boilers are crucial parts; electrode boiler seals are used to prevent water, steam and other media inside the electrode boiler from leaking, and to prevent external air from entering; when the electrode boiler is in operation, the interior is in a high temperature and high pressure state. If the seal is poor, it will not only cause heat energy loss and affect the thermal efficiency of the boiler, but may also cause safety accidents; for example, steam leakage may scald the operator, and water leakage may cause electrical short circuits and other problems; Therefore, in the process of producing seals for electrode boilers, the compression-rebound characteristics of the seals are an important factor affecting their sealing performance. If the compression-rebound characteristics of the seals are poor, when the electrode boiler is frequently started and stopped or the operating conditions change, the seals will be subjected to multiple compression-rebound cycles, thereby reducing the rebound effect of the seals, resulting in reduced sealing effect of the seals. Based on the above problems, it is necessary to test the compression and rebound characteristics of seals during production. In existing factories, compression and rebound tests of seals are mostly performed on dedicated machines, that is, one test device can only test seals of one size at a time, and cannot test seals of multiple sizes at the same time; this results in low test efficiency.

The mounting post 133 drives the first ring 131 to continue to move upward. During the process, the second ring 132 is moved upward by the first slider 136 on the outer side thereof. 36 pushes the No. 1 ring 131 to move upward. During the upward movement of the No. 1 ring 131, the No. 1 slider 136 on the outer side of the No. 1 ring 131 moves upward inside the No. 1 slide groove 135 on the inner side of the mounting plate 13 until the No. 1 slider 136 on the outer side of the No. 1 ring 131 moves to the top of the No. 1 slide groove 135 on the inner side of the mounting plate 13, and the telescopic device 14 stops moving; so that the mounting column 133, the No. 2 ring 132, the No. 1 ring 131 and the mounting plate 13 present a stepped structure; After the mounting column 133, the second ring 132, the first ring 131 and the mounting plate 13 form a stepped structure, the staff will sleeve the corresponding size of the sealing piece on the outer wall of the corresponding mounting column 133, the first ring 131 and the second ring 132; that is, the smallest size of the sealing piece is sleeved on the outer wall of the mounting column 133, the largest size of the sealing piece is sleeved on the outer wall of the first ring 131, and the medium size of the sealing piece is sleeved on the outer wall of the second ring 132; when the sleeve is completed; the telescopic device 14 is retracted; it is particularly important to measure and record the thickness and height of the sealing piece before sleeve installation; When the telescopic device 14 contracts, the mounting column 133 first drives the mounting column 133 to move downward, and the No. 1 slider 136 on the outer side of the mounting column 133 supports the No. 1 slide groove 135 on the inner side of the No. 2 ring 132, so when the mounting column 133 moves downward, the No. 2 ring 132 moves downward; similarly, the No. 1 slider 136 on the outer side of the No. 2 ring 132 supports the No. 1 slide groove 135 on the outer side of the No. 1 ring 131, and the No. 1 ring 131 moves downward synchronously; in this process, the sealing member 136 on the outer side of the mounting column 133 is The seal gradually moves into the placement groove 134 opened on the inner side of the upper end of the second ring 132, the outer side of the second ring 132 is sleeved in the placement groove 134 opened on the inner side of the upper end of the first ring 131, and the seal sleeved on the outer side of the first ring 131 moves into the placement groove 134 opened on the inner side of the upper end of the mounting plate 13; until all the seals enter the corresponding placement grooves 134, at which time the mounting column 133, the second ring 132, the first ring 131 and the upper end surface of the mounting plate 13 are in the same horizontal plane; After the seal enters the placement groove 134, the hydraulic cylinder 15 at the upper end of the mounting plate 12 is extended and retracted, and the hydraulic cylinder 15 pushes the extrusion plate 16 to move downward.

The elastic member 166 is an annular sheet structure, and the elastic member 166 is made of natural rubber. In the initial state, the fifth ring 163, the fourth ring 162 and the third ring 161 are in a stepped structure. At the same time, the elastic member 166 blocks the gap between the third ring 161 and the fourth ring 162, and the elastic member 166 blocks the gap between the fourth ring 162 and the fifth ring 163. At the same time, the elastic member 166 connected to the outer side of the fourth ring 162 is connected at the outer side lower end of the fourth ring 162; the elastic member 166 connected to the outer side of the fifth ring 163 is connected at the outer side lower end of the fifth ring 163; so that when the elastic member 166 on the outer side of the fourth ring 162 is installed, the sealing member is located below the elastic member 166; when the elastic member 166 on the outer side of the fifth ring 163 is installed, the sealing member is located below the fifth ring 163; On the basis of the above-mentioned second embodiment, when the fourth ring 162 slides downward on the outer side of the fifth ring 163, the seal on the outer side of the fifth ring 163 is squeezed by the end of the outer side of the first ring 131 where the placement groove 134 is not provided, and the seal on the outer side of the fifth ring 163 enters the gap between the fourth ring 162 and the fifth ring 163. During the process, the seal on the outer side of the fifth ring 163 squeezes the elastic member 166 between the fifth ring 163 and the fourth ring 162; at the same time, the seal on the outer side of the fourth ring 162 squeezes the elastic member 166 between the fourth ring 162 and the fifth ring 163; When the seal extrusion test is completed, the hydraulic cylinder 15 is retracted upward, the extrusion plate 16 moves upward, and the No. 3 ring 161 moves upward synchronously. During this process, the No. 4 ring 162 is affected by its own gravity and the elastic reset effect of the elastic member 166 between the No. 3 ring 161 and the No. 4 ring 162, and the No. 4 ring 162 and the No. 5 ring 163 remain motionless; until the No. 2 slider 165 on the outside of the No. 4 ring 162 slides to the bottom of the No. 2 slide groove 164 on the inside of the No. 3 ring 161, the No. 3 ring 161 drives the No. 4 ring 162 to move upward, and during this process, the No. 5 ring 1 63 remains different until the second slider 165 on the outside of the fifth ring 163 moves to the lower end of the second slide groove 164 on the inside of the fourth ring 162, and the third ring 161 drives the fifth ring 163 to move upward through the fourth ring 162; until the third ring 161, the fourth ring 162 and the fifth ring 163 form a step shape; and then through the elastic reset of the elastic member 166, the elastic member 166 between the third ring 161 and the fourth ring 162 and the elastic member 166 between the fourth ring 162 and the fifth ring 163 are ejected; thereby improving the convenience of removing the sealing member.
