Abstract
The invention relates to a hand operated and dynamoelectric highly corrosion resistant two way sealed butterfly valve, which is featured by reasonable structure, reliability, compact installation between the axis and the valve plate, reliable opening and closing, two way sealing, is not affected by the direction of flowing medium or location and can be installed at any place of the pipe. The valve shaft adopts the half axis structure and the valve plate adopts the girder construction. The butterfly valve adopts double eccentric sealed construction and when being closed, the seal ring of the valve plate moves to the seal valve seat of flange valve body, extrudes the sealing surface. The seal ring is pressed uniformly and has the function of two way sealing. The seal valve seat of flange valve body is made by means of welding the stainless acid resisting steel and the seal interface of the valve is featured by the corrosion resistance, no fouling and abrasion resistance. The rubber seal ring is fixed on the valve plate through mechanical means, is firm and convenient for field adjustment or replacing the seal ring. The electric actuating device connects with the interface transferring the stator signals to the central control room and the interface receiving the remote control signal to realize the remote control and adjustment. It is widely applied to: oil extraction, chemical industry, petrifaction, coal gas, natural gas, thermoelectricity, hydraulic power plant, steel, municipal construction, tap water, pharmacy, food and other projects and especially to the pipeline transportation.
Description
The present invention relates to improved butterfly valve on a kind of industrial pipeline, be the thin butterfly valve of a kind of body, Vidacare corp has manually and the electric dual-purpose function, has manual and electronic switching mechanism, handwheel can not rotate when electronic, and handwheel can not cause when driving that rotor rotates.Gate valve weight on the existing pipeline is very heavy, can not install on suspended piping, as install and must design a lot of supports, has wasted a large amount of metals and structural material and man-hour, and has influenced the traffic under the pipeline.
The objective of the invention is: a kind of manual and electronic high-corrosion resisting two-way sealed butterfly valve is provided, rational in infrastructure, reliable, axle and valve plate close installation, open and close reliable, has positive and negative two way sealed function, be not subjected to during installation MEDIA FLOW to restriction, be not subjected to the influence of spatial position yet, can be on pipeline install arbitrarily.Valve shaft adopts the semiaxis structure, and valve plate adopts truss structure.Butterfly valve adopts two eccentric sealed structures, and the valve plate seal ring relies on valve seal valve seat crush seal face with center displacement when closing, and the seal ring pressurized is even, and has positive and negative two way sealed performance.Valve seal valve seat built-up welding 1Cr18Ni8Ti Stainless Acid Resistant Steel is made, and valve sealing face has corrosion-resistant non-scaling, and is wear-resistant.Rubber seal is fixed on the valve plate with machinery type, and sound construction is convenient to the on-the-spot seal ring of adjusting or change.Drive unit and valve joint are provided with the shaft sealing inspection and adjust the hole, must not dismantle drive unit and other parts again, and axial seal is adjusted or changed by checking, the valve shaft sealing material adopts Expanded graphite.The drive unit outdoor type can prevent dust fully, protection against the tide and waterproof, and no matter valve is used in any operating mode, and drive unit all is in good lubricating status, guarantees the working life of valve.Butterfly valve is furnished with the adjustable mechanical limit stoper and valve plate opens and closes lever position indicator, and the arrow and the switch printed words sign of tangible switch direction all arranged on the wheel rim of driving handwheel.Vidacare corp has manually and the electric dual-purpose function, has manual and electronic switching mechanism, and handwheel can not rotate when electronic, and handwheel can not cause when driving that rotor rotates.Vidacare corp and configuration are to the interface and the signaling interface of accepting the central control chamber remote control of Central Control Room transmission state signal.Mechanical cover adopts double sealing structure, and has anti-hammering function.
This product has the following advantages: a kind of manual and electronic high-corrosion resisting two-way sealed butterfly valve, include body, mandrel, the valve body mechanical connection, corrosion-resistant characteristics, butterfly plate has cam action and except all contact frictions between Sealing in valve stroke and the valve seat, making it frequent keying is the sealing effect that still has all the time, seal ring contacts with valve seat with certain wrapping angle, face is equivalent to an elongated wedge again around centering on it equably, and make active force be evenly distributed on the valve seat fully, owing to be that valve seat is stressed, valve shaft adopts the semiaxis structure, and valve plate adopts truss structure.Butterfly valve adopts two eccentric sealed structures, and the valve plate seal ring relies on valve seal valve seat crush seal face with center displacement when closing, and the seal ring pressurized is even, and has positive and negative two way sealed performance.Valve seal valve seat built-up welding 1Cr18Ni8Ti Stainless Acid Resistant Steel is made, and valve sealing face has corrosion-resistant non-scaling, and is wear-resistant.Rubber seal is fixed on the valve plate with machinery type, and sound construction is convenient to the on-the-spot seal ring of adjusting or change.
Be widely used in: oilfield exploitation, chemical industry, petrochemical industry, coal gas, rock gas, thermoelectricity, the water power plant, iron and steel, urban construction, tap water, sewage treatment, pharmacy, engineerings such as food are particularly used on the pipeline transport engineering.
The present invention is easy to use, exchange to install light and handy, when below adopting during embodiment, gate valve under pressure and the material and stop valve, its weight only is 1/3 of gate valve and stop valve, so has reduced cost greatly.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.
Fig. 2 is a circuit diagram of the present invention.
Describe details and the working condition that proposes concrete structure according to the present invention in detail below in conjunction with Fig. 1 Fig. 2.
This invention is by 1, end cap, 2, socket head screw, 3, pad, 4, valve rod, 5, copper sheathing, 6, valve body, 7, the dish plate, 8, seal ring, 9, trim ring, 10, hex screw, 11, pin, 12, filler, 13, Gland, 14, support, 15, double-screw bolt, 16, packing ring, 17, stud, 18, nut, 19, manual overvide, 20 motor-driven control devices, compositions such as 21 speed reducer, control speed reducer 21 connects 4 one groups of butterfly plates 7 of valve rod, on valve rod 4, valve body 6 sealing surfaces and butterfly plate 7 sealing couplings are to reach sealing purpose by bolton, the transportation of motorized motions control large diameter pipeline, the special adaptation on the pipeline on the ground environment of the frequent vibrations in roadside, use.
