Abstract
Positive pressure nitrogen protects gas valve body isolation box. The traditional gas control valve is generally installed in a naked mode, and once leakage occurs or sparks are brought in operation, the whole boiler is shut down. The utility model discloses the constitution includes: box (1), the box open and to have circular shape manhole (2) and transparent window (3) of patrolling and examining, a set of gas pipeline (7) certainly the box in pass through, the box with gas pipeline between sealing connection, the box in fill inert gas, the box inboard install long-range gas and reveal alarm (4), gas pipeline on have connected gradually gas filter (12), long-range pressure transmitter (11) and pressure sensor (9), long-range solenoid valve (8), spark arrester (5), the box be whole airtight structure. The utility model discloses with the air isolation protection of gas pipeline.
Description
The technical field is as follows:
the utility model relates to a natural gas power generation safety protection field, concretely relates to malleation nitrogen protection gas valve body shielded cell.
Background art:
the gas control valve that traditional natural gas power plant used generally adopts the exposed mode installation, can't judge directly perceivedly that valve body and junction have or not leak, in case take place to reveal or bring the spark in the operation, can lead to whole boiler blowing out, because there is not enclosure space, makes safety inspection and maintenance all need go on under the safe environment condition of expansion, has both increased the maintenance cycle, also makes the proruption trouble judge the ageing and receive the influence.
The utility model has the following contents:
the utility model aims at providing a malleation nitrogen protection gas valve body shielded cell.
The above purpose is realized by the following technical scheme:
malleation nitrogen protection gas valve body shielded cell, its constitution includes: the box, the box open and to have circular shape manhole and transparent window of patrolling and examining, a set of gas pipeline certainly the box in pass through, the box with gas pipeline between sealing connection, the box in fill inert gas, the box inboard install long-range gas and reveal the alarm, gas pipeline on have connected gradually gas filter, long-range pressure transmitter and pressure sensor, long-range solenoid valve, spark arrester, the box be whole airtight structure.
The positive pressure nitrogen protection gas valve body isolation box is characterized in that the junction of a lead of the remote pressure transmitter, the remote electromagnetic valve and the remote gas leakage alarm and the box body adopts a high-molecular airtight structure, the lower end of a gas pipeline is provided with a dehydrator, the inert gas adopts nitrogen with 0.005-0.02MPa, and an inflation valve and a pressure sensor are installed above the box body and connected with an inflation pipeline.
Has the advantages that:
1. the utility model discloses malleation nitrogen protection gas valve body shielded cell, this structure is kept apart gas operating element and atmosphere through the isolation of box, and general simple regulation and control operation is automatic completion under nitrogen protection, is equipped with the gas in the box and reveals the alarm, in case meet accident, can in time discover at long-range central control room, in time close this pipeline through the solenoid valve to open the manhole position and in time salvage, and then provide a safe combustible gas and control the environment.
The utility model discloses a be filled with inert gas nitrogen gas in the box, can effectual oxygen in the isolation air, the explosion that the little spark that probably produces and arouse in avoiding the operation process simultaneously reduces the risk, and inert gas is injected into by the inflation valve of installation on the box, through the nitrogen gas storage tank connection can.
The utility model discloses being equipped with the spark arrester, effectively cutting off the flame that the output pipeline direction accident was returned and is burnt, effectively reduce the scale of emergent accident.
And through the utility model discloses manometer on the box and transparent window of patrolling and examining can audio-visual display box internal inert gas's pressure variation and inside behavior make maintainer can in time judge the situation in the box, and the very first time provides the safe state situation, has improved gas control security level.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
example 1:
the utility model provides a malleation nitrogen protection gas valve body shielded cell, its constitution includes: box 1, the box open and to have circular shape manhole 2 and transparent window 3 of patrolling and examining, a set of gas pipeline 7 certainly the box in pass through, the box with gas pipeline between sealing connection, the box in fill with inert gas, the box inboard install long-range gas and reveal alarm 4, gas pipeline on have connected gradually gas filter 12, long-range pressure transmitter 11, pressure sensor 9, long-range solenoid valve 8, spark arrester 5, the box be whole airtight structure.
Example 2:
according to embodiment 1 malleation nitrogen protection gas valve body shielded cell, long-range pressure transmitter, long-range solenoid valve, the lead wire 13 of long-range gas leakage alarm with the box junction adopt the airtight structure of polymer, dehydrator 10 is equipped with to the lower extreme of gas pipeline, inert gas adopt have 0.005-0.02 MPa's nitrogen gas, box top install inflation valve 15 and pressure sensor 6 and connect the gas charging line, be equipped with nitrogen sensor on replacing the gas discharging pipeline, can effectively monitor the replacement degree, guarantee that the oxygen concentration in the box is less than the explosion point after mixing with the gas.
Claims (2)
