Abstract
The utility model discloses a three-way butterfly valve. The three-way butterfly valve structurally comprises a valve body, a valve rod and a butterfly plate, wherein, the valve rod in the valve body is embedded in a sleeving hole at one end of the butterfly plate; and a valve body seal ring and a butterfly plate double-side seal ring are arranged in the contact positions between the valve body and a pipe orifice as well as between the butterfly plate and the a pipe orifice. The three-way butterfly valve provided by the utility model is used on a switching pipeline, and has the advantages of fast direction switching, small size, light weight, flexile operation, no abrasion, small opening and closing torque, good sealing performance, no gas/ liquid leakage, seal operation, self-help sealing reliability, aging resistance, abrasion resistance, long service life, and convenient seal ring replacement; the sealing adopts stainless steel; a seal ring of the valve body can be replaced without moving a large-caliber valve; the butterfly valve can optionally be applied on a pipeline under -15 to 425 DEG C; and the butterfly valve is light so as to facilitate high-altitude installation. Therefore, butterfly valve is a novel valve with energy conservation, environmental protection, and cost conservation and can save a plurality of valves.
Description
Technical field
The utility model relates to a kind of butterfly valve, specifically a kind of novel three-way butterfly valve.
Background technique
In the pipeline of carrying liquid or gas, use a large amount of valves, existing valve exists many deck valves door mostly, uses the valve seal friction, the switching time is long, and the switching moment of torsion is big, at switching port many deck valves door will be installed, the cost height, man-hour is many, switches slowly, and weight is big, and maintenance is difficult.In addition since the sealing of valve seal and flashboard rub, the sealing of directly grinding away, lack working life.
The model utility content
(1) technical problem that will solve
Technical problem to be solved in the utility model provides a kind of Three-way butterfly valve at the existing in prior technology defective, has solved the cost height of prior art, and man-hour is many, switches slowly, and weight is big, and maintenance is difficult, the sealing of grinding away, the defective that working life is short.
(2) technological scheme of being taked
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Three-way butterfly valve, structure comprise valve body, valve rod, butterfly plate, seal ring; Valve rod in the described valve body is enclosed in the trepanning of butterfly plate one end, and described valve body and butterfly plate and mouth of pipe contacting point are respectively arranged with valve seals and butterfly plate dual face seals circle.
Described valve seals and butterfly plate dual face seals circle are fixed by the seal ring set screw.Driving mechanism is selected for use, worm gear, electronic, pneumatic, surge, electricity surges, can be closely remote and shake control, the program control work of making an uproar.
The described mouth of pipe also is provided with sealing gasket.
(3) a kind of Three-way butterfly valve of the utility model compared with prior art has following beneficial effect:
A kind of Three-way butterfly valve of the utility model is used in and switches on the pipeline, and switching direction is fast, volume is little, and is in light weight, flexible operation, do not have wearing and tearing, the switching moment of torsion is little, good seal performance, gas liquid does not have leakage, have outside the operation sealing and help sealing reliability automatically, stainless steel is adopted in sealing, and is ageing-resistant, corrosion-resistant, long service life, it is convenient to change seal ring, and not dismounting of large bore valves valve body just can be changed seal ring, be applied in-use arbitrarily on the pipeline of 15-425 degree centigrade, install in the high-altitude of being convenient in light weight, is a kind ofly can save a plurality of valves, energy-conservation again, environmental protection again, the novel valve of cost-saving again.
Description of drawings
Below in conjunction with the drawings and specific embodiments a kind of Three-way butterfly valve of the utility model is described further.
Figure is the structural representation of a kind of Three-way butterfly valve of the utility model.
Among the figure: 1, valve body; 2, valve rod; 3, butterfly plate; 4, valve seals; 5, butterfly plate dual face seals circle; 6, seal ring set screw; 7, seal ring set screw; 8, sealing gasket.
Embodiment
Shown in figure, a kind of Three-way butterfly valve, structure comprises valve body 1, valve rod 2, butterfly plate 3; Valve rod in the described valve body is enclosed in the trepanning of butterfly plate one end, and described valve body and butterfly plate and mouth of pipe contacting point are respectively arranged with valve seals 4 and butterfly plate dual face seals circle 5.
Described valve seals and butterfly plate dual face seals circle are fixing by seal ring set screw 6,7.
The described mouth of pipe also is provided with sealing gasket 8.
Above-described only is the preferred implementation of a kind of Three-way butterfly valve of the utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, all belong to the protection domain of a kind of Three-way butterfly valve of the utility model.
