Need, dress is convenient, light long tube is supplied gas formula positive-pressure biological protective clothing.
The technical solution of the utility model is summarized as follows：
A kind of long tube is supplied gas formula positive-pressure biological protective clothing, including is connected as a single entity by head-shield, jacket, trousers and Protective Boots anti-
Shield takes main body 1, and protective gloves 8 is connected with the gloves retainer ring 9 in protective garment main body, and airtight drawing is provided with protective garment main body
Chain 3, is provided with gas flow regulating valve 4, one-way exhaust valve 10 in protective garment main body, and one end of gas flow regulating valve 4 leads to
Piping is connected with the air-flow distributor 6 being arranged on inside protective garment main body 1, and air-flow distributor 6 leads to protection respectively with 5 again
Take the head in main body 1, the breather pipe 5 of upper limbs and lower limb connects, and the other end of gas flow regulating valve 4 passes through long tube 2 and pressure
Contracting air supply system is connected, and detection mouth 7, airtight slide fastener 3 are provided with the lower section of the gas flow regulating valve 4 of protective garment main body
In the front upper part of protective garment main body, the outlet port of the breather pipe towards protective garment body head is arranged on for the position of setting
The transparent window bottom of head-shield.
The advantages of the utility model：Simple in construction, overall weight is light, and cost is low, and user can easily put on, take off
Under, it is not necessary to other people assistance, the gas of operator's exhalation, which does not haze, does not interfere with operator's vision, can meet bio-safety
Level Four and above laboratory, high-risk biological pollution environmental activity personnel need.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
A kind of long tube is supplied gas formula positive-pressure biological protective clothing, sees Fig. 1 and Fig. 2, including by head-shield, jacket, trousers and Protective Boots
The protective garment main body 1 being connected as a single entity, protective gloves 8 is connected with the gloves retainer ring 9 in protective garment main body, in protective garment main body
Airtight slide fastener 3 is provided with, gas flow regulating valve 4, one-way exhaust valve 10, gas flow regulation are provided with protective garment main body
One end of valve 4 is connected by pipeline with the air-flow distributor 6 being arranged on inside protective garment main body 1, air-flow distributor 6 again with 5
The breather pipe 5 of the head led to respectively in protective garment main body 1, upper limbs and lower limb connects, and the other end of gas flow regulating valve 4 leads to
Cross long tube 2 to be connected with compressed-air supply system, the lower section of the gas flow regulating valve 4 of protective garment main body is provided with detection mouth
7, in the front upper part of protective garment main body, the breather pipe towards protective garment body head goes out for the position that airtight slide fastener 3 is set
Gas port end is arranged on the transparent window bottom of head-shield.
Protective garment main body has good mechanical performance and air-tightness.The mechanical performance of protective garment fabric meets standard GB
24539-2009 requirement, first suppresses 1000Pa during air tightness test, test pressure after 4min, it is found that Decay Rate is small
