Abstract
The invention relates to a hydraulic and hand-actuated thermal-insulation high corrosion-resisting two-way sealing butterfly valve, in which, outside of the valve body are welded and casted an insulated casing and an inlet-outlet connector means butterfly valve. The driving device is incorporated with an interface for transferring state signals to a central control chamber and receiving the signals of the central control chamber, so as to realize the controlled regulation.
Description
The present invention relates to improved butterfly valve on a kind of industrial pipeline, be that the thin hydraulic and hand operated drive unit of butterfly valve of a kind of body has hydraulic and hand operated double-purpose functional, have hydraulic and hand operated switching mechanism, handwheel can not rotate when surging, and handwheel can not cause the rotor rotation of surging when driving.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 hydraulic and hand operated insulation high corrosion resisting bidirectional sealed butterfly valve is provided, it is the thin valve of a kind of body, butterfly valve structure rationally, reliably, axle and valve plate close installation, open and close reliably, have 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 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 body with center displacement and burn-ons outward or cast heat-preservating shell and pass in and out connecting tube device seal valve seat crush seal face when closing, and the seal ring pressurized is even, and has positive and negative two way sealed performance.Valve body is burn-on outward or is cast heat-preservating shell and the making of turnover connecting tube device seal valve seat built-up welding 1Cr18Ni8Ti Stainless Acid Resistant Steel, 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.Hydraulic and hand operated 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.Hydraulic and hand operated 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 hydraulic and hand operated 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.Hydraulic and hand operated drive unit has hydraulic and hand operated double-purpose functional, has hydraulic and hand operated switching mechanism, and handwheel can not rotate when surging, and handwheel can not cause hydraulic and hand operated rotor rotation when driving.Drive unit and the configuration interface and the signaling interface of accepting central control chamber to Central Control Room transmission state signal surges.
This product has the following advantages: a kind of hydraulic and hand operated insulation high corrosion resisting bidirectional sealed butterfly valve, include body, mandrel, valve body is burn-on outward or is cast heat-preservating shell and the connection of turnover connecting tube device for mechanical, valve body is burn-on outward or is cast heat-preservating shell and turnover connecting tube device, the drive unit mechanical connection surges, 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 body with center displacement and burn-ons outward or cast heat-preservating shell and pass in and out connecting tube device seal valve seat crush seal face when closing, and the seal ring pressurized is even, and has positive and negative two way sealed performance.Valve body is burn-on outward or is cast heat-preservating shell and the making of turnover connecting tube device seal valve seat built-up welding 1r1Cr18Ni8Ti Stainless Acid Resistant Steel, 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.
Describe details and the working condition that proposes concrete structure according to the present invention in detail below in conjunction with Fig. 1.
This invention by 1, end cap, 2, socket head screw, 3, pad, 4, valve rod, 5, copper sheathing, 6, valve body is burn-on outward or cast heat-preservating shell and turnover connecting tube device, 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, the driving-controlling device that surges, compositions such as 20 manual operating devices.The driving-controlling device 19 manual operating device control gear 20 that surge connect 4 one groups of butterfly plates 7 of valve rod, by bolton on valve rod 4, valve body is burn-on outward or is cast heat-preservating shell and turnover connecting tube device 6 sealing surfaces and butterfly plate 7 sealing couplings, to reach sealing purpose, use on the special pipeline that adapts on the ground environment that often shakes in the roadside of the driving-controlling device that surges.
