Description
Technical field
The blowdown apparatus in a kind of gas system is the utility model is related to, especially a kind of centralized rapid pollution discharging device.
Background technology
Automatic sewage discharging device in existing gas separation or cleaning system, is broadly divided into two kinds：One is that float-ball type is arranged automatically
Dirty valve, two be electronic type timing blowoff electromagnetic valve.Both blowdown apparatus are all mounted in air accumulator in gas system, carbonated drink point
From device or the housing bottom of filter, this is the place for condensing saturation water discharge.It is clean that the use of blowdown apparatus can improve source of the gas
Cleanliness, protect the service life of downstream gas equipment, improve the operating efficiency of gas.
The general character shortcoming of existing two kinds of blowdown apparatus, it is broken to the rust in pipe network, welding or mach metal
The adaptability extreme difference of the solid granulates of bits and imbedibility, it is easy to blocking, clamping stagnation are resulted in, until operational failure.Float-ball type is certainly
Dynamic blowoff valve, being used for the life-span when ductwork pressure fluctuation is larger has considerable influence, and normal blowdown is time-consuming longer, and source of the gas wave
Take it is more, it is long-term use of less economical.Electronic type timing blowoff electromagnetic valve, by time module or time relay control by setting
Time timing blowdown, is swift in motion, is stable, but influenced by environmental temperature, can not adapt to explosion-proof environment, use limitation
Property is larger.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, and the adaptability of source of the gas cleanliness factor will be got well, be swift in motion,
Source of the gas waste it is small, have blast resistance construction can under inflammable and explosive environment and can under -30~40 DEG C of environment normal work blowdown dress
Put.
Blowdown apparatus designed by the utility model includes blow down branch road, concentrates blowdown main line, a fast pneumatic
Stop valve, an explosion-proof two-position-five-way solenoid valve, described blow down branch road is connected on described blowdown main line, described
Check valve is filled on blow down branch road, the fast pneumatic stop valve concentrated described in the terminal installation of blowdown main line, passes through institute
The explosion-proof two-position-five-way solenoid valve stated starts the opening and closing of stop valve to control.
The utility model is that a subsystem in gas system or neighbouring several subsystems are needed into automatic drainage equipment
Sewage draining exit, individually directly blowdown but do a concentration blowdown main line, by the bye-pass of each sewage draining exit by each sewage draining exit
With concentrate blowdown main line be connected, needed on the bye-pass of each sewage draining exit installation check valve, with avoid because each sewage draining exit pressure difference not
Deng and interacting between causing each sewage draining exit blowdown.Concentrate blowdown main line according to the total quantity of each sewage draining exit bye-pass with
And obtained after processing air volume calculation needed for each waste removal equipment.Blowoff line terminal is being concentrated, one fast pneumatic of installation is cut
Disconnected valve, start the opening and closing of stop valve with an explosion-proof two-position-five-way solenoid valve control so as to realize automatic pollution discharge, blowdown frequency and
Duration is according to pipe network requirement and needs blowdown flow rate to determine, is realized by the PLC control two-position-five-way solenoid valves in system.
The independent blowdown automatically of more table flotation ball or electronic type automatic blowdown valve, make a fast pneumatic stop valve into and concentrate
Blowdown, the waste that source of the gas is discharged at random when substantially reducing blowdown, improves economy；Bigbore pneumatic cut-off valve is to source of the gas
The adaptability of cleanliness factor significantly improves, and is not in caused failure phenomenon, operational reliability in the automatic pollution discharges such as blocking, clamping stagnation
Significantly improve；Electric elements select explosion-proof type two-position-five-way solenoid valve, solve the use range under inflammable and explosive work condition environment；
All master, branch blowoff line and pneumatic cut-off valves are incubated more or electric tracing, can solve normal under extremely low environment
Operation.
The beneficial effects of the utility model be can make gas system operation it is more stable, air source quality is improved significantly,
Source of the gas waste is small, and ductwork pressure is steady, preferably protects the service life of downstream gas equipment.And of the present utility model use the longevity
Life length, without frequently changing the accessories such as blowoff valve, operating cost substantially reduces.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
Embodiment
The utility model is described in detail below in conjunction with embodiment.
The blowdown apparatus designed by the utility model shown in figure includes blow down branch road 1, manual blowdown valve 2, unidirectional
Valve 3, concentrate blowdown main line 4, a fast pneumatic stop valve 5, an explosion-proof two-position-five-way solenoid valve 6.
Sewage draining exit arranged at equipment (such as filter) bottom for discharging impurity needed for gas system, and the impurity in gas passes through
Blow down branch road 1, by check valve 3, enter and concentrate blowdown main line 4 to be automatically drained out again by fast pneumatic stop valve 5.Row
Manual blowdown valve 2 is additionally provided with dirty bye-pass 1.It can make when automatic pollution discharge failure or when other need the situation of manual blowdown
Use manual blowdown valve.
A subsystem in gas system or neighbouring several subsystems are needed to the sewage draining exit of automatic drainage equipment, it is not single
Solely directly blowdown but it is connected to by blow down branch road 1 and concentrated on blowdown main line 4, and on blow down branch road 1 plus
Fill check valve 2, with avoid because the pressure difference of each sewage draining exit does not wait and caused by interacting between each sewage draining exit blowdown.
Blowdown main line 4 is concentrated to handle tolerance according to needed for the total quantity on each blow down branch road 1 and each waste removal equipment
Obtained after calculating.The terminal of blowdown main line 4 is being concentrated, a fast pneumatic stop valve 5 is being installed, with an explosion-proof two-position five-way
The control of magnetic valve 6 starts the opening and closing of fast pneumatic stop valve 5 so as to realize automatic pollution discharge, and blowdown frequency and duration are according to pipe
Net requires and needs blowdown flow rate to determine, is realized by the PLC control two-position-five-way solenoid valves 6 in system.
