Description
Technical field
The present invention relates to subsurface drainage field, relate in particular to a kind of explosion-proof gas defence deodorization multifunctional floor drain.
Background technology
Common floor drain in existing engineering is mainly comprised of manhole cover, water storage seat, manhole cover with drain hole is placed in the cannelure of water storage seat, manhole cover upper section is on the standpipe of " U " type and water storage seat between the formed standpipe of alice, to be water storage ditch, and water storage seat is longitudinally connected on the standpipe of three water service pipes.Water storage ditch is darker, and water-holding quantity is larger, and odor-resistant result is better, the structure of tradition odour-proof floor drain, because water storage seat is assembled on three water service pipes, must improve accomodation ground height, increase construction volume, cannot deepen the degree of depth of water storage ditch, cause water storage ditch shallow, how between 5mm-15mm, water-holding quantity is few, easily evaporation, most importantly bears the positive/negative pressure producing while incessantly draining the sewage away, and odor-resistant result is bad.
Summary of the invention
The object of this invention is to provide a kind of explosion-proof gas defence deodorization multifunctional floor drain, to solve the floor drain protection airtight gas defence deodorization in existing underground protective engineering passage, the technical problem that fragile, perishable, maintenance cost is high, maintenance management is inconvenient.
For achieving the above object, the present invention adopts following technical scheme:
Explosion-proof gas defence deodorization multifunctional floor drain of the present invention comprises that floor drain body, Cancellation Missed, Cancellation Missed handle, seal and deodorized valve form; Cancellation Missed is positioned at the top open part of floor drain body; Cancellation Missed handle is positioned on Cancellation Missed, and seal is positioned at the cavity of the leakage body of Cancellation Missed below, and seal is connected by hold-down screw with Cancellation Missed handle; Deodorized valve is positioned at the below of seal, and in leaking the lower ending opening place of body.
Seal below is provided with seal washer, and there is a trim ring seal washer outside, and seal washer and trim ring are fixed on seal by attachment screw.
Deodorized valve is comprised of deodorization valve body, deodorization valve gap and deodorization valve gap back-moving spring; Deodorization valve gap is positioned at the bottom of deodorization valve body; Deodorization valve body is to be connected by deodorization valve gap back-moving spring with deodorization valve gap.
Deodorized valve is arranged on sewer pipe, under the effect of deodorization valve gap back-moving spring, in normally off, prevents on foul smell anti-; When having current through herein time, deodorized valve is opened under flow action.
Above Cancellation Missed, be distributed with drain hole.Cancellation Missed can rotate by rotation Cancellation Missed handle, and 60 degree that turn clockwise can make seal close, and is rotated counterclockwise 60 degree and can makes seal open.
Floor drain body material is HT250 cast steel structure, and Cancellation Missed, seal and deodorized valve are stainless steel 1Cr18Ni9Ti.
During installation, the end face seat of floor drain is lower than ground 5-10mm.
Seal washer is solid high resiliency anti-aging corrosion resistant rubber.
Be used in air raid shelter, be arranged on the guard plot leading on people guard plot gutter in addition inner.All tubing of drainage system and annex should adopt steel pipe or feedwater cast iron pipe.During installation, non-of the top of floor drain seat is lower than ground 5-10mm.
Blastproof strainer has several specifications such as DN50, DN80, DN100, DN150.
Concrete material has two kinds of cast iron blastproof strainer and stainless steel blastproof strainers.
Stainless steel blastproof strainer: material: shell HT250, outer ring and spool are stainless steel 1Cr18Ni9Ti,
1), FBFDDCr DN80 appearance and size: outside diameter 175mm, floor drain height 130mm, wall thickness 10mm, 3 cun of gas thread connections.
2), FBFDD DN100 appearance and size: outside diameter 225mm, floor drain height 135mm, wall thickness 10mm, 4 cun of gas thread connections.The water seal height of blastproof strainer is 30mm.
Described explosion-wave-preventing floor drain is applicable to newly-built or reconstructs the floor drain device for draining waste that diffuser casing in all kinds of air defense basements, wash and disinfectant house, gas defence passage etc. need to rinse room, at ordinary times in closed condition.Seal is placed on Lou in body cavity, and clockwise direction rotate approximately 60 degree can complete airtight locking (otherwise counterclockwise rotate 60 degree, can exit), can prevent exploding shock wave when airtight and other toxic gases enter guard plot, play the effect of security protection.When wartime, this location contamination needed to clean, floor drain can be opened, carry out draining.
Described explosion-wave-preventing floor drain is installed and is used: 1, this explosion-wave-preventing floor drain product is arranged on the drainage pipe place of civil air defense constructions and installations, and floor drain, in opening, guarantees normal draining at ordinary times.Wartime, floor drain Cancellation Missed declined, and screwed counterclockwise rear enclosed outfall, prevented shock wave, and poison gas enters people defence area, and can check underground water and pour in down a chimney.When 2, explosion-wave-preventing floor drain is installed, floor drain body and sewer pipe screw thread are constructed after tightening again, and upper cover top surface should be lower than concrete water plane 5～10mm.3, explosion-wave-preventing floor drain should regularly clean foreign material after installing and using.4, explosion-wave-preventing floor drain sealing joint strip checked once every 1 year, and long-term use found the corrosion of floor drain body sealing surface, answers processing of rust removing, and maintenance.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention has the advantages that intensity is high, lightweight, processing is installed easily, working service is convenient, maintenance cost is low, reach required intensity, rigidity, anticorrosion and airtight requirement completely, be applicable to underground protective engineering.
The explosion-proof odour-proof floor drain benefit analysis of people's air defense of the present invention: 1, principle: do not need water seal, utilize water flow pressure automatically to regulate deodorant cover sealing mat to open and close by spring.2, material: high-quality environment-friendly materials, body foundry goods, seal are made by stainless steel quality material, shock-resistant, high temperature resistant.3, feature: (1) seals deodorant cover completely when current reach certain pressure, the sealing mat of floor drain bottom is opened automatically, direct drainage; (2), after mosquito-insect-proof draining, deodorant cover, by gravity auto-closing, forms sealing completely, prevents that mosquito and cockroach etc. from returning and entering in engineering through floor drain along sewer pipe.
Explosion-wave-preventing floor drain of the present invention is that can prevent shock wave and the poison gas that in civil air defense constructions and installations, adopt enter the floor drain of engineering inside, with the difference of common floor drain be to have anti-buffer brake, can resist shock wave.Be very easy to install, in the bottom of blastproof strainer, have screw thread, can directly be connected on and on steel pipe, carry out technological processing for explosion protection feature.Deodorized valve design makes it be easily installed in lower discharging tube mouth.Effectively improved the integral level of engineering protection.So the relatively existing floor drain of the present invention has had obvious difference and progress.
