Description
Technical field
The present invention relates to the rupture disk field, especially relate to a kind of temperature, pressure double-action flameproof apparatus.
Background technique
Blasting piece device is by pressure differential, non-automatic urgent pressure relief device of closing, and mainly for the protection of pressurized container, pipeline or other closed system, it is avoided because excessively superpressure or vacuum cause destroying.Blasting piece device be widely used in now the industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection ground equipment in.
The conventional blasting method sheet can only explosion under a certain setting pressure, and its bursting pressure is determined by under a certain assigned temperature, carrying out burst pressure tests.But some occasion, because temperature variation causes the performance of medium, huge change occurs, this change will make a big impact to the safety of equipment, and at this time rupture disk can explosion because equipment does not reach predetermined bursting pressure, therefore the unsafe factor that the variation of temperature causes can't be got rid of.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of temperature, pressure double-action flameproof apparatus of releasing that all can reach in order to overcome the defect that above-mentioned prior art exists under setting temperature or pressure condition.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of temperature, pressure double-action flameproof apparatus, it is characterized in that, this device comprises Change-over frame, fixing frame, gasket seal, rupture disk, hinge, link and fusing pin, described Change-over frame is located at the top of fixing frame, described gasket seal is located between Change-over frame and rupture disk, described rupture disk is located at the bottom of fixing frame, described hinge is located at the right side of device, two ends are connected with Change-over frame and fixing frame respectively, described link is located at the left side of device, upper end is connected with Change-over frame, and described fusing pin arranges between link press span lower end and fixing frame.
Described gasket seal seals under the pretightening force of fusing pin.
Described rupture disk is the pressure releasing element, can select different rupture disk structures according to setting relieving pressure and bleed outlet footpath.
The material of described fusing pin is the low melting alloy material, this fusing pin Connection Bracket pretension gasket seal, and this fusing pin can rupture while reaching predetermined temperature fast, and fixing frame is rotated counterclockwise 90 ° of media of releasing along hinge.
Compared with prior art, the present invention is simple in structure, easy to use, and all can reach the purpose of releasing at setting temperature or under the setting pressure condition, Applicable scope is wider, has solved the more potential safety hazard that causes dielectric behavior to change producing due to temperature variation.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of temperature, pressure double-action flameproof apparatus, its structure as shown in Figure 1, this device comprises rupture disk 1, fusing pin 2, link 3, gasket seal 4, Change-over frame 5, fixing frame 6 and hinge 7, this device is contained in device housings 8, Change-over frame 5 is located at the top of fixing frame 6, between gasket seal 4 is set, under the pretightening force of fusing pin 2, seal, rupture disk 1 is located at the bottom of fixing frame 6, rupture disk 1 is for controlling the bursting pressure under setting temperature, it is the setting pressure element of releasing, can select different rupture disk structural types according to different setting relieving pressures and bleed outlet footpath, set bursting pressure once reach when the equipment internal pressure, rupture disk 1 is opened, relieving pressure, the pressure release direction straight up.Hinge 7 is located at the right side of device, and two ends are connected with Change-over frame 5 and fixing frame 6 respectively, and link 3 is located at the left side of device, and upper end is connected with Change-over frame 5, and lower end is connected with fixing frame 6 through fusing pin 2.The material of fusing pin 2 is the low melting alloy material, can Connection Bracket 6 in when normal operation, can play the effect of the pre-tightening seal of gasket seal 4 again, assurance fixing frame 6 does not drop and does not leak with gasket seal 4 place's media, when reaching predetermined temperature, can automatically rupture, make whole device because deadweight is rotated counterclockwise 90 ° along hinge, to reach the purpose of the medium of releasing; Link 3 works to connect fusing pin 2 and Change-over frame 5; 5 connection functions that connect whole temperature, pressure double-action flameproof apparatus and device housings 8 of Change-over frame; Hinge 7 fuses and plays the effect of trip shaft when pin works when temperature action.
Service condition of the present invention is as shown in Fig. 2～3, and certain equipment normal operating pressure is 0.1MPa, and operating temperature is 60 ℃, and the explosion temperature of the rupture disk 1 of customization is 60 ℃, bursting pressure 0.2MPa, and the fracture temperature of fusing pin 2 is 120 ℃.When the equipment normal working, fusing pin 2 Connection Brackets 6 and link 3, play fixedly fixing frame 6 and the pretension seal action that guarantees gasket seal 4, and medium is not leaked.When superpressure occurs device interior for a certain reason, and the device interior temperature is unchanged, and when this pressure reaches 0.2MPa, the rupture disk action, open automatically, relieving pressure, as shown in Figure 2.When causing temperature for some reason, device interior raises fast, and now internal pressure remains on 0.1MPa substantially, because pressure does not arrive the 0.2MPa set, therefore rupture disk 1 can not move to open and releases, but the rising of temperature causes and has a strong impact on the safety of equipment, once the temperature of device interior reaches 120 ℃ of setting, fusing pin 2 is fracture automatically just, whole fixing frame overturns 90 ° counterclockwise along hinge 7, and as shown in Figure 3, thereby the medium of releasing guarantees device security.
