Summary of the invention
In order to overcome the operating mode lower valve base that in prior art, ordinary ball valve is large at fluid pressure difference, flow velocity is high, be easy to be washed out, and valve seat cannot meet the problem of high temperature media usage requirement, the utility model provides a kind of novel multiplex ball valve, this multiplex ball valve not only has the good regulatory function of butterfly valve, the sealability simultaneously with closed circuit ball valve, and applicable high temperature media is used, reliability is strong.
The utility model solves the technological scheme that its technical problem adopts: comprise valve body, valve rod, spool and valve seat, valve rod drives the Spool rotating in valve body, spool coordinates with valve base sealing, valve seat adopts flexible graphite material, valve rod is through spool, fixing butterfly plate on valve rod in spool, the upper end of spool is offered annular and is driven groove, annular drives the annular drive plate that in groove, installation matches, between the cell wall of the Pan Bi of annular drive plate and annular driving groove, form relatively symmetrically two independently driver slots, roller is set in driver slot, valve rod drives annular drive plate to rotate.
Valve seat is placed in the frame groove of bracing ring, and bracing ring is fixed on the valve body of spool both sides.
Butterfly plate is fixed on valve rod by straight pin.
The utility model, by above-mentioned specific design, not only has the good regulatory function of butterfly valve, has the sealability of closed circuit ball valve simultaneously, and applicable high temperature media uses, and has advantages of compact structure, easy for operation, reliability strong, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, detailed content of the present utility model is described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve rod 2, spool 3 and valve seat 4, valve rod 2 drives spool 3 rotations in valve body 1, spool 3 is sealed and matched with valve seat 4, valve seat 4 adopts flexible graphite material, the valve seat 4 of flexible graphite material is placed in the frame groove of bracing ring 10, in order to avoid stressed avalanche damages, bracing ring 10 is fixed on the valve body 1 of spool 3 both sides.Valve rod 2 is through spool 3, fixing butterfly plate 5 on the valve rod 2 in spool 3, and butterfly plate 5 is fixed on valve rod 2 by straight pin 11.The upper end of spool 3 is offered annular and is driven groove 6, annular drives the annular drive plate 7 that in groove 6, installation matches, between the cell wall of the Pan Bi of annular drive plate 7 and annular driving groove 6, form relatively symmetrically two independently driver slots 8, roller 9 is set in driver slot 8, and valve rod 2 drives annular drive plate 7 to rotate.Accompanying drawing is depicted as spool 3 and butterfly plate 5 all in fully open position, and the fluid flow passing through is maximum.When valve rod 2 clockwise directions rotate, drive annular drive plate 7 to rotate, annular drive plate 7 drives again roller 9 in the interior rolling of driver slot 8.At this moment spool 3 does not rotate, and the butterfly plate 5 being connected with valve rod 2 is closed gradually in spool 3, and the flow flowing through reduces gradually from maximum, and when turning to 90 ° of positions, butterfly plate 5 reaches the position of full cut-off, and fluid is completely severed.If valve rod 2 is rotated further subsequently, 7 of annular drive plates by roller 9 band movable valve plugs 3 rotate together with ball butterfly plate 5 butterfly plate 5 with spool 3 now without relative movement, when turning to 180 °, spool 3 cuts off passage completely, and keeps sealing state, vice versa.Adopt the valve seat 4 of flexible graphite material to there is good decay resistance, except strong oxidizing property medium as chloroazotic acid, nitric acid, concentration be more than 60% chromic acid, dichromic acid, potassium permanganate etc., the corrosion of the acid of any concentration of ability, alkali, salt and all organic compounds.Expanded graphite has particularly preferred self-lubricating property, during the suitable low and metal friction of friction factor, is 0.04-0.05.It also has very high thermal conductivity [116-128W/(m ℃)], lower linear expansion coeffcient (2-3 * 10
-6/ ℃) and good heat-resisting and heatproof degree performance jumpy.In reducing atmosphere, serviceability temperature is-200-1000 ℃.The mechanical processing characteristic of Expanded graphite is good, can carry out various machining.Expanded graphite also has following feature: 1, good flexibility, and under the condition of adhesive-free and bulking agent, with still having 10%-15% elasticity after mold pressing and continuous rolled-on method machine shaping on its thickness direction.During as sealing material, part corresponding to it has good contact, and therefore lower impacting force just can reach sealing; 2, the resistance to irradiation of heat-and corrosion-resistant, Expanded graphite can bear the superhigh temperature from the low temperature to 3650 of-200 ℃ ℃, and in this temperature range, its physical and mechanical property does not have any variation; 3, good self-lubricating property and impermeable performance, the combination force between crystal the same as native graphite is little, and interlayer easily slides and therefore has good self-lubricating property under external force.The seal ring that Expanded graphite is used for to valve seat has following characteristics: 1, heat resistance is higher than special macromolecular material, 300 ℃ of the valve base sealing material contraposition polyphenyl maximum operation (service) temperatures that in special macromolecular material, heatproof is the highest, and Expanded graphite is 600 ℃ as valve seat maximum operation (service) temperature; 2, metal sealing valve seat maximum operation (service) temperature is suitable, and the material maximum operation (service) temperature of conventional metal sealing is 600 ℃; 3, to compare seal pressure little with metal sealing valve seat; 4, to compare friction factor little with metal sealing valve seat; 5, to compare valve opening and closing moment little with metal sealing valve seat; 6, compare sealability with metal sealing valve seat and had reliable assurance; 7, compare valve low cost of manufacture, good in economic efficiency with metal sealing valve seat.Above-described embodiment is described the preferred implementation of a kind of novel multiplex ball valve of the utility model; not the design of model utility and scope are limited; do not departing under the prerequisite of the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model, all should fall into the protection domain of a kind of novel multiplex ball valve of the utility model.
