Description
Technical field
The utility model relates to a kind of for the pressure relief device on reactor, belongs to chemical industry equipment field.
Background technology
Reactor is generally airtight container to ensure inner effecting reaction, but the gas of producing while reaction easily makes still internal pressure raise, if the generation that corresponding pressure relief device easily causes the perils such as blast is not set. And traditional pressure relief device conventionally rises in process at pressure and throws open, more violent to pressure measurement spool impulse ratio, easily there is the situation of pressure measurement spool clamping stagnation, impact resets.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide the pressure relief device on a kind of reactor, can repeatedly reuse, and still internal pressure leakage is when the normal value, and pressure relief device is closed pressure relief opening, ensures to reseal in still.
For achieving the above object, the utility model provides following technical scheme: a kind of for the pressure relief device on reactor, comprise kettle, kettle top is provided with relief tube, relief tube side is provided with bypass pipe, bypass pipe comprises a pressure relieving end straight up, in pressure relieving end, slippage is combined with pressure measurement slide block, pressure relieving end sidewall is provided with pressure relief opening, pressure relief opening is opened or closed to pressure measurement slide block induction kettle internal pressure also accordingly, pressure relieving end top is provided with exhaust outlet, described exhaust outlet is connected with discharge duct, described pressure relief opening is connected with relief pipeline, the outlet of described discharge duct is linked on relief pipeline, described discharge duct is provided with one-way throttle valve, described one-way throttle valve comprises that parallel connection is arranged in check valve and the choke valve on discharge duct, when exhaust outlet is during from pressure relieving end Exhaust Gas, gas flow is through choke valve, in the time that gas enters into pressure relieving end from exhaust outlet, gas flow is through check valve.
Preferably, the outlet of described relief pipeline straight down.
Preferably, described pressure measurement slider top is connected with boosting-rod, and boosting-rod stretches out pressure measurement end, the boosting-rod extension afterburning piece that has been threaded.
Preferably, the top of described relief tube is connected with Pressure gauge by pressure-measuring pipe, and described pressure-measuring pipe is provided with curled portion.
Compared with prior art, the beneficial effects of the utility model are: when still internal pressure jumps, gas pressure overcomes pressure measurement slide block gravity and it is upwards pushed up, and pressure relief opening is communicated with in still, discharge gas reactor; In the process of upwards pushing up due to pressure measurement slide block, the space on pressure relieving end top is compressed, gas will be discharged from choke valve, due to the damping action of choke valve, that pressure measurement slide block does not have the lofty property quickly rising to, but lentamente to rising, stability while ensureing the slippage of pressure measurement slide block, is not prone to clamping stagnation; Reply normally when internal gas pressure, pressure measurement slide block declines, and it is large that pressure relieving end upper space becomes, gas will reenter pressure relieving end top, if now gas is from choke valve process, certainly will affects pressure measurement slide block and move down speed, affect off-period, therefore check valve is set and ensures that gas passes through smoothly.

Detailed description of the invention
A kind of for the pressure relief device on reactor, comprise kettle 1, kettle 1 top is provided with relief tube 2, relief tube 2 sides are provided with bypass pipe 3, bypass pipe 3 comprises a pressure relieving end 3a straight up, in pressure relieving end 3a, slippage is combined with pressure measurement slide block 7, pressure relieving end 3a sidewall is provided with pressure relief opening 5a, pressure measurement slide block 7 is responded to kettle 1 internal pressure and is opened accordingly or close pressure relief opening 5a, pressure relieving end 3a top is provided with exhaust outlet 4a, described exhaust outlet 4a is connected with discharge duct 4, described pressure relief opening 5a is connected with relief pipeline 5, the outlet of described discharge duct 4 is linked on relief pipeline 5, described discharge duct 4 is provided with one-way throttle valve 6, described one-way throttle valve 6 comprises that parallel connection is arranged in check valve 6b and the choke valve 6a on discharge duct 4, when exhaust outlet 4a is during from pressure relieving end 3a Exhaust Gas, gas flow is through choke valve 6a, in the time that gas enters into pressure relieving end 3a from exhaust outlet 4a, gas flow is through check valve 6b. when still internal pressure jumps, gas pressure overcomes pressure measurement slide block 7 gravity and it is upwards pushed up, and pressure relief opening 5a is communicated with in still, discharges gas reactor, in the process of upwards pushing up due to pressure measurement slide block 7, the space on pressure relieving end 3a top is compressed, gas will be discharged from choke valve 6a, due to the damping action of choke valve 6a, that pressure measurement slide block 7 does not have the lofty property quickly rising to, but lentamente to rising, stability while ensureing 7 slippage of pressure measurement slide block, is not prone to clamping stagnation, when internal gas pressure is replied normal, pressure measurement slide block 7 declines, it is large that pressure relieving end 3a upper space becomes, gas will reenter pressure relieving end 3a top, if now gas passes through from choke valve 6a, certainly will affect pressure measurement slide block 7 and move down speed, affect off-period, therefore check valve 6b is set and ensure that gas passes through smoothly.
Wherein, the outlet of relief pipeline 5 straight down. Arranging is downwards for fear of disorderly spray of the gas of discharging, and especially avoids being sprayed onto staff.
Wherein, pressure measurement slide block 7 tops are connected with boosting-rod 8, and boosting-rod 8 stretches out pressure measurement end, the boosting-rod 8 extensions afterburning piece 9 that has been threaded. Boosting-rod 8 and afterburning piece 9 are set can increase the gravity of pressure measurement slide block 7, can tackle normal pressures different in reactor, adapts to the needs of various working environments. Afterburning piece 9 adopts the mode being threaded to be fixed on boosting-rod 8, for convenience detach and replacing.
Wherein, the top of relief tube 2 is connected with Pressure gauge 10 by pressure-measuring pipe 11, and described pressure-measuring pipe 11 is provided with curled portion 11a. Pressure gauge 10 is set and can facilitates staff to observe still internal pressure, psychology has preparation, if not so pressure measurement slide block 7 has blocked to regulate and malfunctioningly just bothered. It is to play cushioning effect that curled portion 11a is set, and avoids pressure suddenly too high to Pressure gauge 10 generation impacts.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
