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 is mainly used in protection pressurized container, pipeline or other closed system, and it is avoided because of excessively superpressure or vacuum cause destroying.Blasting piece device be widely used in now industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection ground equipment in.
Conventional rupture disk can only explosion under a certain setting pressure, and its bursting pressure is confirmed through under a certain assigned temperature, carrying out burst pressure tests.But some occasion; Because temperature variation causes that huge change takes place the performance of medium; 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, so the unsafe factor that variation of temperature causes can't be got rid of.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned existing technology existence a kind of temperature, pressure double-action flameproof apparatus of releasing that under setting temperature or pressure condition, all can reach to be provided.
The object of the invention can be realized through following technological scheme:
A kind of temperature, pressure double-action flameproof apparatus 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 the rupture disk, and described rupture disk is located at the bottom of fixing frame, and 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, and the upper end is connected with Change-over frame, and described fusing pin is provided with between link press span lower end and the fixing frame.
Described gasket seal seals under the pretightening force of fusing pin.
Described rupture disk is the pressure releasing element, can directly select different rupture disk structures with bleed outlet according to setting relieving pressure.
The material of described fusing pin is the low melting alloy material, this fusing pin Connection Bracket and pretension gasket seal, and this fusing pin can rupture when 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, and is easy to use, and perhaps under the setting pressure condition, all can reach the purpose of releasing at setting temperature; Applicable scope is wider, has solved the more potential safety hazard that causes dielectric behavior to change producing owing to temperature variation.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of temperature, pressure double-action flameproof apparatus, its structure is as shown in Figure 1, and 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 the device housings 8, and 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, and rupture disk 1 is used to control the bursting pressure under the setting temperature; It is the setting pressure element of releasing; Can directly select different rupture disk structural types according to different setting relieving pressures and bleed outlet, in case when the equipment internal pressure reaches the setting bursting 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 the upper end is connected with Change-over frame 5, and the 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 when proper functioning; Can play the effect of the pretension sealing of gasket seal 4 again, guarantee that fixing frame 6 does not drop and gasket seal 4 place's media do not leak, when reaching predetermined temperature, can rupture automatically; 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 interconnect functions that connect whole temperature, pressure double-action flameproof apparatus and device housings 8 of Change-over frame; Hinge 7 fuses when temperature action and sells the effect of playing trip shaft when working.
Use condition of the present invention is 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 takes place in device interior for a certain reason, and device interior temperature no change, when this pressure reached 0.2MPa, the rupture disk action was opened automatically, and relieving pressure is as shown in Figure 2.Raise fast when device interior causes temperature for some reason, and this moment, internal pressure remained on 0.1MPa basically, because pressure does not arrive the 0.2MPa that sets; So rupture disk 1 can not move to open and releases, but the rising of temperature causes the safety of equipment and has a strong impact on, in case the temperature of device interior reaches 120 ℃ of setting; Fusing pin 2 is fracture automatically just; Whole fixing frame overturns 90 ° along hinge 7 counterclockwise, and is as shown in Figure 3, thereby the medium of releasing guarantees device security.
