Description
Technical field
Civil air defense constructions and installations equipment technology field is the utility model is related to, particularly belongs to a kind of gas-particulate filter with quick connection
Head.
Background technology
Gas-particulate filter is divulged information as wartime air-raid shelter filters the important equipment of poison, because its nicotine-filtering medium amount has certain threshold
Value, when reaching its filter poison limiting threshold value, needs to change gas-particulate filter.And in contamination between the filter poison where gas-particulate filter
Area, when replacing, staff, which need to dress biochemical defence suit, breathing mask, gas-protection boot, can just enter between filter poison.During replacement, work
It is more short better that personnel must control replacing construction, and as the working time is long, the filter poison ability of breathing mask can not support, just
Mortal injury can be caused to staff.
The connection of gas-particulate filter and ventilation duct is still by the way of screw group at present, and because screw is more, a filtering is inhaled
The average replacing construction for receiving device is about 50 minutes, and because labor intensity is larger, can accelerate the breathing of staff, accelerates gas defence face
The rate of ventilation of tool, the effective time of breathing mask are further shortened, and serious security risk is brought for staff.
Utility model content
The purpose of the utility model is to provide a kind of gas-particulate filter fast connector, the prior art is overcome not
Foot, it is proposed that a kind of fast connector of gas-particulate filter, realizes fast quick-detach, greatly reduce labor intensity.
The technical solution adopted in the utility model is as follows：
A kind of gas-particulate filter fast connector, including inlet attack and outlet connection, the inlet attack and filtering
Diffuser on absorber is connected, and the diffuser is equipped with connecting flange at air inlet, and the inlet attack is connected to method
On blue end face, rotation set, the company of the rotation set and inlet attack jointly are sleeved on the outside of the outlet connection and inlet attack
The junction at the place of connecing, rotation set and outlet connection is equipped with sealing rubber ring, is socketed with tracheae outside the afterbody of the outlet connection, institute
Tracheae is stated to be fixedly connected on outlet connection by clip.
The outlet connection and inlet attack are equipped with ladder shaft part, the periphery of the afterbody major diameter section of the ladder shaft part
Connection screw thread is equipped with, the periphery of the head path section of the ladder shaft part is equipped with the arc groove of annular.
The bottom surface of the rotation set is the ladder shaft part to match with outlet connection and inlet attack, and in both ends major diameter section
Inner hole surface is equipped with connection screw thread, and the corresponding arc groove of arc groove with annular is equipped with the inner hole surface of middle part path section,
The rotation set is connected by screw thread with outlet connection and inlet attack respectively, and close by the sealing rubber ring in arc groove
Envelope.
Connection screw thread on the outlet connection and inlet attack is oppositely oriented.
The exterior lateral of the outlet connection is equipped with annular groove, and the clip is located at the outside of annular groove, the gas
Pipe is embedded in groove by clip.
Compared with the prior art, the beneficial effects of the utility model are as follows：
The utility model realizes being bi-directionally connected for gas-particulate filter and exterior tracheae by using the mode of threaded connection, adopts
With oppositely oriented double thread structure, realization synchronously screws, and the requirement of air-tightness can be realized by circumferential sealing rubber ring,
It is convenient for disassembly and assembly quick, it is easy to operate, labor intensity is greatly reduced, the time of replacement is shortened, improves work safety.
