The basic concept definition of bursting disc
:
Bursting disc safety device (bursting disc
+
holder)
: consists of bursting disc and clamping device The non-reclosing device is a pressure relief device composed of parts such as the regulator.
Bursting disc
: It is a pressure sensitive component that acts quickly due to overpressure. (To put it bluntly, it is a protection device for protecting equipment to prevent explosion due to excessive pressure. It is used to relieve pressure.)
Clamp
: The function of the clamp is to provide a safe release amount consistent with the container. The medium discharge nozzle is equivalent. The periphery of the explosion bursting disc is firmly clamped and tightly sealed. It matches the bursting disc components so that the pressure can be relieved within the calibrated bursting disc pressure. Generally, there are upper and lower clamps, which can be equipped with sealing gaskets. (lozenge).
Reinforcement ring
: In the combined bursting disc, it is an annular ring that closely fits the edge of the bursting disc and plays a role in enhancing its edge stiffness.
Back pressure difference
: Under normal operating conditions, when the pressure on the discharge side of the rupture disc safety device is higher than the pressure on the inlet side, including the inlet side, it is in a negative pressure (i.e. vacuum, negative pressure is pressure) state When, the two sides of the bursting disc form a pressure difference in the opposite direction of pressure relief. This pressure difference is called back pressure difference.
Back pressure bracket
: In the combined bursting disc, it is used to prevent the bursting disc from accidental damage due to back pressure difference
Bursting disc product types:
Positive Arch-slit type bursting disc
: The structure is a combined bursting disc. The bursting disc and back-pressure bracket are opened with holes and slits (radial or circumferential slits) that weaken the material strength, which will cause overpressure. Tensile failure occurs at the interface with the minimum pore spacing
. Suitable for use in both gas and liquid media and low pressure conditions.
3. When determining the bursting temperature, consider the suitable temperature of the sealing film to ensure sealing performance
. The maximum working pressure must reach
. Debris may be generated, and it is not recommended to be connected in series with the safety valve.
Ordinary arched bursting disc (
)
: The bursting disc is a single-layer diaphragm. The wall thickness of the overpressure arched disc will be thinned and damaged by tension.
/> .Suitable for use in gas and liquid media and working conditions with relatively high pressure of bursting discs
3. With a bracket, it can withstand back pressure
.The maximum working pressure is higher than the minimum bursting pressure
. It may produce fragments. It is not recommended to be used in series with the safety valve, which is more dangerous.
. Because there may be material restrictions (usually stainless steel 3.3 is used), the processing burst pressure has certain limitations.
Positive arch grooved bursting disc (
)
: The structure is a single-layer diaphragm. The arch surface is carved with cross grooves and annular grooves that weaken the strength. It is pulled from the grooves when overpressure occurs. Stretch failure
. Suitable for both gas and liquid media and working conditions with high burst pressure
. The maximum working pressure can reach the minimum burst pressure
. No fragments are produced during blasting, and can be used with Safety valves are used in series
． There are no sparks during blasting
Reverse-arched crocodile-tooth bursting disc
: Suitable for gas phase media, good ability to withstand back pressure, can withstand full vacuum without brackets, anti-fatigue, no debris generated, More suitable for use in equipment with low pressure
Reverse arched slotted bursting disc
:
This model is generally used on sanitary equipment in pharmaceutical factories. There is no spark during blasting and it is suitable for gas phase. Medium, suitable for use in equipment with lower pressure
Reverse arched slotted bursting disc (
)
: The structure is a single-layer arched diaphragm, and the concave surface of the arch is engraved with cross weakening groove, the bursting disc will tear and release along the groove after instability and overturning.
. Adapted to gas phase media
. Good ability to withstand pressure, can withstand full vacuum without brackets
. Maximum working pressure can reach minimum burst pressure
. Anti-fatigue, Can be used in situations with pulsating pressure
. No fragments after blasting, can be used in series with safety valves
. No sparks after blasting
Flat-plate slotted bursting disc
: round shape Flat slit type and square flat slit type, square is generally standard, while round is non-standard and needs to be customized.
It is composed of bursting disc, sealing film, and back-pressure bracket. The bursting disc and back-pressure bracket have holes and slits (slits on all four sides) that weaken the material strength. The overpressure is at the interface with the smallest hole spacing. Tensile failure.
.The working medium is suitable for gas phase and liquid phase. It is suitable for equipment with low pressure and large discharge diameter. It is often used in dust storage equipment.
