Abstract
The invention relates to a fire hydrant valve. The fire hydrant valve comprises a valve body, wherein a valve deck is connected to the left upper end of the valve body, an inlet channel and an outlet channel are formed in the lower end and right upper end of the valve body respectively, a valve seat is hinged to the left side wall of the valve body and located at the upper end of the inlet channel, a gasket is connected to the lower end of the valve seat through a bolt, a water outlet cover is connected to the upper side of the outlet channel, a fire hydrant valve rod is connected to the center of the valve deck in a sleeved mode, a positioning ring is arranged between the fire hydrant valve rod and the valve deck, an O-shaped ring and a first sealing ring are arranged between the fire hydrant valve rod and a copper nut, a second sealing ring is arranged between the upper end of the copper nut and the valve deck, a sliding groove is formed in the upper end of the valve seat, a connecting base in sliding fit with the valve seat is installed in the sliding groove, and the upper end of the connecting base is fixedly connected with the fire hydrant valve rod. The fire hydrant valve has the advantages that sealing performance is higher, liquid backflow preventing performance is higher, and service life is long.
Description
Technical field
The present invention relates to valve, specifically a kind of fire hydrant valve.
Background technique
Fire hydrant valve is a kind of one way stop peturn valve, and it except ensureing the water outlet of the unidirectional water inlet by lower end of water (flow) direction to upper end, the most important thing is to ensure the working life of sealing in valve body and valve seat in use.
Be disclose a kind of underground hydrant in CN102002967 in China Patent Publication No., it comprises body, be arranged on the water intake for being connected with water pipe on described body, for the water outlet be connected with outside water-band, be arranged on described body interior control described in water outlet water outlet whether valve assembly and be arranged on the cap on described water outlet top, described valve assembly comprises spool, the valve rod be connected with described spool, be arranged on the valve gap on described body, it is outside that described valve gap is stretched out on described valve rod top, bottom described spool, described water intake is covered, first center line at described water intake place parallels with second center line at described water outlet place.
Foregoing invention is disposed with copper nut, snap ring, copper ring from top to bottom between valve rod and valve gap, and is provided with O RunddichtringO in joint.Although this mode has ensured the sealing between valve rod and copper nut, between copper nut and valve gap, but do not do any Sealing Device, the important step that this this easy generation is leaked.In addition, the mode that valve seat is pulled open by spacing spiral is not rigorous, and during closedown, must close by manual rotation, this " shut " mode" is completely not rigorous, probably can not close completely and shut valve seat, makes to stop the function of liquid backflow to be difficult to effectively be realized.
Summary of the invention
For above-mentioned technical problem, the present invention proposes on the basis of above-mentioned fire hydrant, can further poppet body inner sealing and stop the valve body of characteristic of liquid backflow, i.e. a kind of fire hydrant valve.
A kind of fire hydrant valve, comprise valve body, described valve body left upper end is connected with valve gap, described valve body lower end, upper right side is respectively equipped with inlet passage, outlet passage, the valve body left side wall of described inlet passage upper end is hinged with valve seat, described valve seat lower end has been bolted pad, outflow cover for water is connected with above described outlet passage, described bonnet central is socketed with hydrant valve rod, positioning ring is provided with between described hydrant valve rod and valve gap, O type circle and seal ring one is provided with between described hydrant valve rod and copper nut, seal ring two is provided with between described copper nut upper end and valve gap, described valve seat upper end is provided with chute, described chute is built with the connecting base be slidably matched with valve seat, described connecting base upper end and hydrant valve rod are connected.Seal ring two can effectively prevent liquid from leaking from copper nut and valve cover chamber, and hydrant valve rod and valve seat be slidably matched when having ensured that flow of fluid stops, valve seat can fall automatically closes good inlet passage completely, ensures its characteristic stoping liquid backflow.
The invention has the beneficial effects as follows: core of the present invention increases the sealing of valve inner further by the mode of adding seal ring between copper nut and valve gap, feature of the present invention be sealing and stop liquid backflow functional better, when using the life-span long.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, invention is further illustrated.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the I place close-up schematic view of the present invention about Fig. 1.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As depicted in figs. 1 and 2, a kind of fire hydrant valve, comprise valve body 1, described valve body 1 left upper end is connected with valve gap 5, described valve body 1 lower end, upper right side is respectively equipped with inlet passage 1a, outlet passage 1b, valve body 1 left side wall of described inlet passage 1a upper end is hinged with valve seat 2, described valve seat 2 lower end has been bolted pad 3, outflow cover for water 9 is connected with above described outlet passage 1b, described valve gap 5 central sleeve is connected to hydrant valve rod 4, positioning ring 6 is provided with between described hydrant valve rod 4 and valve gap 5, O type circle 11 and seal ring 1 is provided with between described hydrant valve rod 4 and copper nut 7, seal ring 2 10 is provided with between described copper nut 7 upper end and valve gap 5, described valve seat 2 upper end is provided with chute 2a, described chute 2a is built with the connecting base 8 be slidably matched with valve seat 2, described connecting base 8 upper end and hydrant valve rod 4 are connected.Seal ring 2 10 can effectively prevent liquid from leaking between copper nut 7 and valve gap 5, and hydrant valve rod 4 and valve seat 2 be slidably matched when having ensured that flow of fluid stops, valve seat 2 can fall automatically closes good inlet passage 1a completely, ensures its characteristic stoping liquid backflow.
Before use, outflow cover for water 9 is opened, outlet passage 1b is connected with water pipe.Open inlet valve.
During use, only need exert oneself upwards to pull hydrant valve rod 4, water can flow into from inlet passage 1a, flow out from outlet passage 1b behind valve body 1 inside, hand is unclamped after finishing using, under gravity, hydrant valve rod 4, connecting base 8, valve seat 2 automatically can fall block input port passage 1a and prevent liquid backflow.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed the present invention.Application claims protection domain is defined by appending claims and equivalent thereof.
