Abstract
The utility model discloses an overpressure protector which comprises a first pressure guide pipe and a second pressure guide pipe, wherein one end of the pressure guide pipe is an inlet and the other end of the pressure guide pipe is an outlet; external threads are arranged on the inlet and the outlet; the first pressure guide pipe is provided with a telescopic stop valve; one end of the second pressure guide pipe is communicated with the inlet, and the other end of the second pressure guide pipe is connected with the telescopic stop valve, thereby forming a straight sealing section which is internally provided with a movable interlayer which can move along with the change of pressure; a control connecting rod of the telescopic stop valve is also arranged in the sealing section; the end part of the control connecting rod is connected with the movable interlayer; and a spring is arranged between the movable interlayer and the telescopic stop valve. The overpressure protector is simple in structure, can be manufactured and assembled conveniently, and can cut off the pressure when the tested pressure is excessively high, can play the protection role when the excessive pressure exists, and can automatically recover to test the pressure when the pressure is normal.
Description
Technical field
The utility model relates to gas phase or liquid-phase tube linear pressure container overvoltage protective device in a kind of industrial processes, especially a kind of overvoltage protector.
Background technique
In various production processes, all can use pressure gauge, pressure transmitter at present; and during tested overpressure, tend to make pressure instrumentation to damage, or cause production accident; bring inconvenience to production, but so overvoltage protector of people's cut-out pressure when always expecting a kind of tested overpressure.
Summary of the invention
But the overvoltage protector of cut-out pressure when the purpose of this utility model is a kind of tested overpressure that designs for the deficiency that solves above-mentioned technology.
The overvoltage protector that the utility model is designed comprises first PRESSURE PIPE, and first PRESSURE PIPE, one end is import, and the other end is outlet, all is provided with external connection screw in described import and the outlet, and described first PRESSURE PIPE is provided with a telescopic type stop valve; Also comprise second PRESSURE PIPE, this second PRESSURE PIPE, one end is communicated with described import, its the other end links to each other with the sealing of telescopic type stop valve, and form a straight seal section, be provided with in the sealing section one with variation in pressure mobile mobile interlayer, the control link of described telescopic type stop valve also is arranged in the sealing section, and the end of this control link links to each other with described mobile interlayer, is provided with spring between described mobile interlayer and the telescopic type stop valve.When tested overpressure, the second PRESSURE PIPE internal pressure also increases thereupon, and mobile interlayer moves and pressure spring towards the telescopic type stop valve, drives the control link action of telescopic type stop valve simultaneously, until the path that cuts off first PRESSURE PIPE, thereby play the overvoltage protection effect of cutting off; When tested overpressure reduced, spring recovered, with pneumatic interlayer toward returning back to top, simultaneously with control link toward pulling back, make the path conducting again of first PRESSURE PIPE, normal pressure measurement.Described mobile interlayer can be a piston, and as preferably, described mobile interlayer is an air film, and air film can be fixedly installed in the seal section, and the deformation that produces by its pressurized realizes the action back and forth of control link, compares the movable back and forth easier sealing of piston.
As preferably, also comprise a clutch movably, this clutch passes described second PRESSURE PIPE, and the one end is connected with mobile interlayer, the other end links to each other with a snubber, described snubber is provided with spacing reception and registration point, and described second PRESSURE PIPE is provided with the spacing point relative with described spacing reception and registration point, and clutch can move with mobile interlayer, when pressure is excessive, spacing reception and registration point is contacted with spacing point, therefore can outwards provide a switching signal, be used for controlling alarm.
As preferably, also comprise alarm, this alarm is connected with described snubber signal, thereby can make overvoltage protector itself promptly have the warning effect.The preferred illuminator of alarm.
The overvoltage protector of the utility model gained, simple in structure, fabrication and installation are convenient, but cut-out pressure during tested overpressure when overvoltage, can play a protective role, pressure just often can recover pressure measurement again automatically.
