Abstract
The utility model provides safe and reliable, avoids a kind of device for safety valve protection of moist chlorine corrosion.Its technological scheme is: form primarily of relief pipeline (1), front slip-knot (2), ceramic layer (3), flash chamber (4), one-way valve (5), noble gas room (6), safety valve (7), rear slip-knot (8), air valve (9), feed channel (10), noble gas valve (11) and noble gas apotheca (12); Relief pipeline (1) connects flash chamber (4) by front slip-knot (2), flash chamber (4) internal layer is provided with ceramic layer (3), flash chamber (4) connects noble gas room (6) by one-way valve (5), noble gas room (6) connection safety valve (7), safety valve (7) connects air valve (9) by rear slip-knot (8), air valve (9) connects feed channel (10), and noble gas room (6) connect noble gas apotheca (12) by noble gas valve (11).The utility model practicality reasonable in design, has saved cost of production, avoids safety valve and corrodes from moist chlorine, has both improve Security and in turn ensure that economic benefit.
Description
Technical field
The utility model relates to valve technology field, especially a kind of device for safety valve protection.
Background technique
According to the regulation of relevant law, regulation, regulations, liquid chlorine storage tank must arrange safety valve, and the gas after pressure release is caused the absorption of accident tower, avoids befouling environment.The inlet pipeline of safety valve outlet and accident directly links together by traditional pressure relief device, along with time lengthening safety valve occur seal leakage or take-off device malfunctioning, a large amount of safety valves is caused to damage, not only each safety valve price, at about 60,000 yuan, causes benefit impaired but also can cause a hidden trouble to safety in production.
Summary of the invention
The purpose of this utility model be exactly for prior art exist defect, provide a kind of safe and reliable, avoid moist chlorine corrosion a kind of for safety valve protection device.Its technological scheme is: relief pipeline connects flash chamber by front slip-knot, flash chamber internal layer is provided with ceramic layer, flash chamber connects noble gas room by one-way valve, noble gas room connection safety valve, safety valve connects air valve by rear slip-knot, air valve connects feed channel, and noble gas room connects noble gas apotheca by noble gas valve.
The utility model practicality reasonable in design, has saved cost of production, avoids safety valve and corrodes from moist chlorine, has both improve Security and in turn ensure that economic benefit, is applicable to popularity and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, for a device for safety valve protection, form primarily of relief pipeline 1, front slip-knot 2, ceramic layer 3, flash chamber 4, one-way valve 5, noble gas room 6, safety valve 7, rear slip-knot 8, air valve 9, feed channel 10, noble gas valve 11 and noble gas apotheca 12; Relief pipeline 1 connects flash chamber 4 by front slip-knot 2, flash chamber 4 internal layer is provided with ceramic layer 3, flash chamber 4 connects noble gas room 6 by one-way valve 5, noble gas room 6 connection safety valve 7, safety valve 7 connects air valve 9 by rear slip-knot 8, air valve 9 connects feed channel 10, and noble gas room 6 connects noble gas apotheca 12 by noble gas valve 11.
The utility model technological process: owing to being provided with one-way valve 5, the pressure upper/lower positions sealing to remain on protection gas is fixed.Under normal circumstances; safety valve 7 seals position discord moist chlorine contact; once safety valve 7 starts; pressurized gas are washed one-way valve 5 open and pressure are let out accident tower; and in noble gas room 6, supplement process air or nitrogen by the uninterrupted small flow of noble gas apotheca 12 spray along the wall body of noble gas room 6; to keep malleation, the gate valve of protection safety valve 7.
Claims (1)
