Abstract
The utility model relates to a medium -low pressure reducing valve set, its characterized in that: be responsible for including admitting air with the branch pipe more than two, each branch pipe is parallelly connected to communicate with each other with admitting air to be responsible for to be connected, and each branch pipe follows gas flow direction and connected gradually preceding stop valve, Y appear filter, relief pressure valve and stop check valve and relief valve, the outlet side that each branch pipe is located the stop check valve is connected with the communicating tube replacement of cutting way, just it installs the switching stop valve on the road to cut tube replacement. The utility model discloses compact structure, occupation space position are few, and it is nimble convenient to use, and the decompression is stable.
Description
Technical field
This utility model relates to a kind of medium-low pressure reducing valve group, belongs to air relief valve technical field.
Background technology
It is usually mounted with high pressure air bottle, by the high pressure air that is stored in high pressure air bottle through decompression on medium-sized boats and ships
After reach pressure required during main engine starting, gas is delivered to main frame.For reducing in-site installation air relief valve and phase stop valve
And the installation period of filter sum and regulation, the pipeline between main frame and high pressure air bottle is provided with stop valve, mistake
The pressure that filter and air relief valve and screw down nonreturn valve combination are constituted subtracts valve group, has compact conformation, can improve in-site installation effect
Rate, shortens installation period, and the advantage that can form modularized production.But disclose distant medium-low pressure reducing valve group parallel connection at present to be connected to
One bypass pipe, is provided with bypass cutoff valve on bypass pipe, by controlling the bypass cutoff valve on bypass pipe, it is simple to right
Air relief valve keeps in repair and uninterruptedly supplies.Although bypass cutoff valve has certain decompression, but stop valve cannot substitute decompression
Valve, therefore when non-stop run, can cause post-decompression gas pressure unstable, and affect the starting performance of main frame.
Summary of the invention
The purpose of this utility model to be to provide a kind of compact conformation, the position that takes up room few, flexible and convenient to use, decompression is steady
Fixed medium-low pressure reducing valve group.
This utility model is that the technical scheme reaching above-mentioned purpose is: a kind of medium-low pressure reducing valve group, it is characterised in that: include
Air inlet supervisor and plural arm, each arm in parallel connection with air inlet supervisor communicates, and each arm is along gas flow direction
Being connected with front stop valve, Y-filter, air relief valve and screw down nonreturn valve and relief valve in turn, each arm is only positioned at cut-off
Return the outlet side of valve to connect and have a switching pipeline communicated, and on switching pipeline, switching stop valve is installed.
Medium-low pressure reducing valve group of the present utility model have employed air inlet and is responsible for and is connected in parallel on plural on air inlet supervisor
Pipe, and it is connected with front stop valve, Y-filter, air relief valve and cut-off non-return in turn along gas flow direction on the pipe of each road
Valve and relief valve, reduced pressure to air-flow by the air relief valve on each arm and arrive operating pressure, by multiple front stop valves, Y
Shape filter, air relief valve and screw down nonreturn valve and relief valve are connected by each arm and integrated, compact conformation, volume
Little and take up space little.This utility model can use flexibly by controlling the selection that switching stop valve can realize the gas outlet of valve group,
Owing to being mounted on air relief valve on each arm, the most no matter air-flow is by any one arm, can ensure gas after decompression
The stability of body, can meet the job requirement of main frame, can meet again not shut down and carries out Maintenance and Repair, by air inlet supervisor and
The outlet of each arm pipeline at the scene connects, and in-site installation efficiency is greatly improved, and shortens installation period.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of this utility model medium-low pressure reducing valve group.
Wherein: 1 air inlet supervisor, Pressure gauge before 2,3 arms, stop valve before 4,5 Y-filters, 6 subtract
Pressure valve, 7 screw down nonreturn valves, 8 switching stop valves, Pressure gauge after 9,10 relief valve, 11 switching pipelines.
Detailed description of the invention
As shown in Figure 1, medium-low pressure reducing valve group of the present utility model, including air inlet supervisor 1 and plural arm 3,
Each arm 3 in parallel connection with air inlet supervisor 1 communicates, and can be supplied to main frame by multichannel arm 3, or by the arm set
3 groups of main frame supply
As shown in Figure 1, each arm of this utility model 3 is connected with front stop valve 4 in turn along gas flow direction, Y shape filters
Device 5, air relief valve 6 and screw down nonreturn valve 7 and relief valve 10, gas medium by front stop valve 4 and Y shape filter with
After air relief valve 6, reduce to required operating pressure, follow-up pipeline is supplied.Y-filter 5 of the present utility model
Sewage draining exit be connected with blow-off pipe, outside the miscellaneous discharge pipe of matter after filtering, and prevent reducer unit from existing by screw down nonreturn valve 7
After entrance point mistake power, the phenomenon that medium flows backwards.
As shown in Figure 1, this utility model is provided with relief valve 10 in the outlet of each arm 3, the pressure in each arm 3
Time too high, relief valve 10 starts action, the pressure of gas, exactness pipeline safety in the corresponding arm 3 of release.See Fig. 1
Shown in, when the air relief valve 6 in one of them arm 3 breaks down and need to overhaul, air relief valve 6 can be connected to by control
Anterior front stop valve 4 and the screw down nonreturn valve 7 at rear portion, close the medium before and after air relief valve 6 in pipeline, the most right
Air relief valve 6 keeps in repair.
As shown in Figure 1, each arm of this utility model 3 be positioned at screw down nonreturn valve 7 outlet side connect have the switching pipeline communicated
11, switching pipeline 11 is provided with switching stop valve 8, each arm 3 can be realized by decompression by controlling switching stop valve 8
After gas supply main frame, it is possible to Jiang Ke mono-road arm 3 as standby, supply during go wrong after, can by control
System switching stop valve 8, makes gas medium discharge from the outlet of this arm 3 and realizes supplying to main frame.
As shown in Figure 1, this utility model is Pressure gauge 2 before air inlet is responsible for and is provided with on 1, and at least one arm 3 is in safety
The inlet side of valve 10 is provided with rear Pressure gauge 9, this utility model also can after each arm 3 is mounted on Pressure gauge 9, energy
Understand the decompressed pressure before and after reducer unit in time.
