Abstract
This utility model relates to a kind of Novel cleaning clean room and enters singly to go out depressed control device with double, including admission line and outlet pipe, it is characterized in that: described admission line UNICOM the first air inlet branch road and the second air inlet branch road, described first air inlet branch road and the second air inlet branch road all with outlet pipe UNICOM, it is provided with switch valve on described first air inlet branch road and the second air inlet branch road, gas flows to the first air inlet branch road and the second air inlet branch road through admission line, then flows to outlet pipe.The beneficial effects of the utility model this utility model reliability is high, does not affect terminal unit and use during maintenance.
Description
Technical field
This utility model relates to a kind of clean gas chamber pipe network system, particularly relates to subtracting in a kind of operating room pipe network
Pressure control device.
Background technology
Hospital operating room, particularly obstetrics and gynecology operation room etc. are in addition to having high request to indoor sanitation, to operation room air
Require high, such as the humid control in operating room, this kind of operating room also known as toilet (Clean Room), also known as without
Dirt room, refers to, in the range of certain space, the pollutant such as the micropartical in air, noxious air, antibacterial are reduced to prescription
Once, and by indoor temperature, cleanliness factor, room pressure, air-flow quick-freezing and air flow method, the illumination of noise vibration machine, electrostatic control
System specially designed room in a certain range of needs.Whether the humidity in operating room is bigger to can infected have after operation in patients
Impact.No matter how the most external air conditions changes, its property such as the indoor cleanliness factor that original setting all can be maintained to require and humidity
Energy.Clean operating room humid control generally takes the principle of humidity priority, as a example by Fresh air handling units of asking for, at its air
Reason process carries out degree of depth dehumidifying for first new wind and return air being mixed, and to 90% apparatus dew point, is then reheated to ventilation state point,
After deliver to indoor, wet more than the waste heat in decontamination chamber.
Various gas pipeline has been installed in toilet and ward mostly, including oxygen channel, fresh air pipeline and other
The gas pipeline needed, for effectively controlling gas conveying, is required for a pressure control device and controls gas conveying, often through
Depressed control device is controlled.Existing depressed control device is all single channel, and once pipeline or interface are out of order, often
Have influence on terminal unit to use；Pipeline carries out cleaning when safeguarding, terminal unit can not normally use, extremely inconvenience.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of Novel cleaning clean room is used
Double entering singly to go out depressed control device, it includes a standby admission line and outlet pipe, simple in construction, though need to safeguard or
Maintenance system, nor affects on terminal unit and uses.
This utility model be the technical scheme is that to include admission line and outlet pipe, described admission line UNICOM
First air inlet branch road and the second air inlet branch road, described first air inlet branch road and the second air inlet branch road all with outlet pipe UNICOM, institute
State and be provided with switch valve on the first air inlet branch road and the second air inlet branch road, gas through admission line flow to the first air inlet branch road and
Second air inlet branch road, then flow to outlet pipe.
By such scheme, also including boost gauge and outlet pressure table, described boost gauge arranges on admission line,
Being positioned near admission line and the first air inlet tributary interface, described outlet pressure table is arranged on the second air inlet branch road, is positioned at
Near two air inlet branch roads and outlet pipe interface.
By such scheme, the first air inlet branch road and or the second air inlet branch road on be additionally provided with air relief valve, gas is through switch valve
Flow to air relief valve.
This utility model has the beneficial effects that:
1, it is transferred to outlet pipe due to the gas of admission line input by the first air inlet branch road and the second air inlet branch road,
Ensure that the most any air inlet branch road breaks down, all can keep in repair, it is only necessary to close this air inlet branch road, open another air inlet
Branch road, and do not affect and give vent to anger, it is ensured that terminal provisioning；
2, this utility model is provided with air relief valve, can effectively adjust admission line and outlet pipe pressure, improve equipment
Reliability；
3, this patent simple in construction, cheap for manufacturing cost.
Accompanying drawing explanation
Fig. 1 is this utility model structure diagram.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not limited to this utility model.
Fig. 1 shows concrete structure of the present utility model, is described further this utility model in conjunction with view.
The arrow of Fig. 1 is imitated table and is represented gas flow.
This utility model be the technical scheme is that to include admission line 1 and outlet pipe 2, described admission line 1
Logical first air inlet branch road 3 and the second air inlet branch road 4, described first air inlet branch road 3 and the second air inlet branch road 4 all with outlet pipe 2
UNICOM, described first air inlet branch road 3 and the second air inlet branch road 4 are respectively provided with switch valve 10 and switch valve 5, and gas is through air inlet pipe
Road stream 1 is to the first air inlet branch road 3 and the second air inlet branch road 4, then flows to outlet pipe 2.
By such scheme, also include that boost gauge 9 and outlet pressure table 12, described boost gauge 9 arrange air inlet pipe
On road 1, being positioned near admission line 1 and the first air inlet branch road 3 interface, described outlet pressure table 12 is arranged on the second air inlet branch road
On 4, it is positioned near the second air inlet branch road 4 and outlet pipe 2 interface.It is respectively provided with on first air inlet branch road and the second air inlet branch road
Air relief valve 11 and air relief valve 7, gas first flows to switch valve, then flows to air relief valve.
This device is fixed on casing 14, and the body in device is fixed on casing 14 by buckle 8.
