Description
Technical field
The utility model belongs to a kind of fire fighting extinguisher, especially belongs to a kind of new type water fire hydrant.
Background technique
Existing water fire hydrant structure mostly includes sequentially connected valve body, flap, valve shaft, valve deck, mortar board, is usually led to
It crosses rotation mortar board and drives valve shaft that flap is driven to move up and down linearly the open and close for realizing flap, to realize traditional water
With fire hydrant full-gear and closed state.Currently, existing water fire hydrant is mostly by between valve shaft and valve deck contact site
The O-ring seal of installation and the sealing for realizing valve shaft and valve deck, the O-shaped sealing used between this valve shaft and valve deck contact site
Circle sealing means cause poorly sealed drainage occur sometimes because of single sealing；Furthermore existing water fire hydrant, also not
It is able to achieve online replacement valve shaft sealing ring, when O-ring seal ageing failure between valve shaft and valve deck contact site, existing water is used
Also it there is also leak at fire hydrant valve shaft, then just existing water need to be all dismantled with fire hydrant could replace, and delay the fire that disappears
The normal use of bolt increases water fire hydrant maintenance cost.How to realize prevents water fire hydrant single with valve deck because of valve shaft
It seals and causes poorly sealed and drainage occur；How to realize that water can replace valve shaft sealing ring with fire hydrant online, improves
Water fire hydrant maintenance working efficiency, the maintenance cost and labor intensity for reducing water fire hydrant are problems to be solved.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of new type water fire hydrants.It is used using the new type water
Fire hydrant can prevent from causing poorly sealed because of valve shaft and the single sealing of valve deck and drainage occurs；It is able to achieve the water fire that disappears
Bolt can replace valve shaft O-ring seal online, improve the water fire hydrant maintenance working efficiency, reduce the maintenance of the water fire hydrant
Cost and labor intensity.
The technical solution that the utility model solves above-mentioned technical problem is: a kind of new type water fire hydrant, including valve body, valve
Valve, valve shaft, valve deck, valve shaft and valve deck contact site are provided with O-ring, it is characterized in that: further include gland, gland using bolt with
Valve deck is fixedly connected；Further include the second road sealing device being arranged between gland and valve shaft, further includes being set between gland and valve deck
The sealing device set further includes the automatic freezing-protective dew valve for being fixedly mounted on one side bottom of valve body；
The second road sealing device being arranged between the gland and valve shaft is 2 O-ring seals, which connects with valve shaft
It is 2/3 circular annular groove that 2 cross sections are disposed on inner wall between touching, and 2 O-ring seals are sequentially arranged at gland
2 cross sections being arranged on inner wall are in 2/3 circular ring-shaped slot, and 2 cross sections being arranged on the gland inner wall are 2/3 round
2 O-ring seals being installed in annular groove are respectively with the valve shaft in sealing cooperation；
The sealing device being arranged between the gland and valve deck is 1 O ' type sealing ring, top surface and gland on the valve deck
Bottom surface be in contact between position on to be provided with 1 cross section be 2/3 circular annular groove, 1 O ' type sealing ring successively pacifies
1 cross section being arranged mounted in top surface on valve deck is to use 1 cross of top surface setting on bolt, valve deck in 2/3 circular ring-shaped slot
Section is that 1 O ' type sealing ring being installed in 2/3 circular ring-shaped slot compresses gland, valve bonnet seal；
The automatic freezing-protective dew valve uses the prior art.
When the utility model new type water fire hydrant set condition, by rotating clockwise mortar board, driving valve shaft drives valve
Valve moves downward, and until the valve seat on the sealing ring and valve body on flap is in close contact, i.e., water is in close state with fire hydrant；
When the utility model new type water fire hydrant working condition, by rotating mortar board counterclockwise, driving valve shaft drives valve
Valve moves upwards, and the valve seat on sealing ring and valve body on flap is promoted to progressively disengage, and the fire water in fire_fighting pipe network is from valve body
Inlet enter fire hydrant, until the top of flap is contacted with the lower plane of valve deck, i.e., fire hydrant is shown in a fully open operation, this
When connect corresponding extension tube attached and carry out out above-water method.
When the utility model new type water is in close state with fire hydrant, automatic drip water valve is automatically drained out remaining water in bolt, and
When fire hydrant is in working condition, because being acted on by hydraulic pressure, automatic drip water valve, which is automatically closed, no longer to be drained.
The utility model maintenance process is: using when the new type water fire hydrant passes through, sets for many years between gland and valve shaft
When there is ageing failure in 1 O ' type sealing ring of the sealing device being arranged between 2 O-ring seals and gland and valve deck set,
The utility model water is in close state with fire hydrant, mortar board, bolt is successively removed, removes gland, can replace online at this time
1 O ' type of the sealing device being arranged between 2 O-ring seals and gland and valve deck being arranged between gland and valve shaft seals
Circle, it is not necessary that the utility model fire hydrant to be replaced to 2 O-ring seals being arranged between gland and valve shaft again after dismantling in pipeline
And 1 O ' type sealing ring of the sealing device being arranged between gland and valve deck.
The beneficial effects of the utility model are: gland is solid using bolt and valve deck since the utility model is provided with gland
Fixed connection.It is also provided with the second road sealing device between gland and valve shaft, sealing device is also provided between gland and valve deck, also
Automatic freezing-protective dew valve including being fixedly mounted on one side bottom of valve body.The second road sealing device being arranged between gland and valve shaft
For 2 O-ring seals, the sealing device being arranged between gland and valve deck is 1 O ' type sealing ring.Realize valve shaft and gland and
The double containment of valve deck, it is therefore prevented that the utility model water fire hydrant causes poorly sealed appearance because of valve shaft and the single sealing of valve deck
Drainage occur, also achieve the utility model water and replace O-ring seal between valve shaft and gland online with fire hydrant
And O ' type the sealing ring between gland and valve deck, improve the water fire hydrant maintenance working efficiency, reduce maintenance, maintenance
Labor intensity and maintenance cost.Remaining water noresidue in the utility model water fire hydrant is also achieved, the utility model is increased
Suitable environment applicability, severe cold area solve the antifreeze technical problem of severe cold area water fire hydrant.
