Abstract
The utility model relates to a seal element pressure relief device which comprises a fixing plate and a support column, wherein the fixing plate is used for plugging a pressure relief hole in the outer wall of a seal element; the inner wall of the fixing plate is installed on the outer wall of the seal element in a fit manner; the fixing plate is provided with an air ventilation hole communicated with the pressure relief hole; one end of the support column is connected with the outer wall of the fixing plate, and the other end of the support column is provided with a compression plate; a movable cover plate capable of moving along the support column and covering the air ventilation hole of the fixing plate is arranged between the fixing plate and the compression plate; the support column is provided with a spring; one end of the spring is connected with the compression plate, and the other end of the spring is fixed on the movable cover plate, and the movable cover plate is compressed on the outer wall of the fixing plate through spring force of the spring. The utility model discloses the seal element pressure relief device, when a seal element is exploded internally, explosion air pressure can be relieved timely and rapidly; and the device is small in structure, saves spaces and cost, is simple in structure, is safe and reliable, and is extremely high in reliability of achieving the pressure relief and anti-explosion function.
Description
Technical field
The utility model relates to a kind of Sealing pressure relief device.
Background technique
Be arranged in the Sealings such as current transformer on locomotive, subway, motor-car, high iron product, high-voltaghe compartment a large amount of electric capacity, high-speed circuit breaker have been installed, if these device blasts, to produce very large blast air pressure in the current transformer that seals, high-voltaghe compartment, security incident occurs at this point.
But at present for converter cabinet, this Sealing of high-voltaghe compartment, do not have reliable blast protection pressure relief device, most of product is to be connected in the insurance that cabinet door and cabinet are done some safety chains or keeper subclass, but this kind structure is also unreliable, at explosion time, blast air pressure is very likely washed the cabinet door open fast, causes the accident.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of Sealing pressure relief device, can drain quickly blast air pressure, and Accident prevention occurs.
The technical solution of the utility model is, a kind of Sealing pressure relief device comprises the fixed plate for shutoff Sealing outer wall relief hole, and the inwall of this fixed plate is fitted and is arranged on the Sealing outer wall, and described fixed plate is provided with the exhaust port that is communicated with relief hole; This device also comprises pillar, one end of pillar is connected with this fixed plate outer wall, and the other end of pillar is installed pressure strip, be provided with between described fixed plate and pressure strip and can move and can cover along pillar the removable cover of fixed plate exhaust port, on described pillar, spring is housed, one end of spring is connected with pressure strip and the other end of spring is fixed on removable cover, and by the elastic force of spring, this removable cover is pressed on the fixed plate outer wall.
Under normal circumstances, spring force is pressed on the fixed plate outer wall with removable cover, reaches sealing effect; When blasting in Sealing, pressurized gas press to mobile plate from the exhaust port of relief hole on fixed plate of Sealing outer wall, mobile plate moves laterally along pillar, holddown spring, pressurized gas are discharged through exhaust port, after pressurized gas were drained, compacted spring pushing tow mobile plate again was pressed on the fixed plate outer wall.
Described fixed plate inwall outer is provided with the fixed plate Stamping Steel Ribbon, and the removable cover inwall outer that contacts with fixed plate is provided with the removable cover Stamping Steel Ribbon; Prevent Leakage Gas, reach better sealing effect.
The utility model is a kind of Sealing pressure relief device, when blasting in Sealing, can drain quickly blast air pressure, and this apparatus structure is small and exquisite, saves space and cost; Simple in structure, safe and reliable, realize that the reliability of the fried function of decompression explosion-proof is strong.
