Abstract
The planar sealing three-way valve is especially suitable for use in petroleum, chemical, power generating and other industry. It consists of valve casing with connecting pipe, upper and lower covers, connected sealing unit, and opening/closing unit. The sealing unit includes the butterfly valve comprising butterfly plate with spring, steel ball and sealing part and the valve seat fixed on the valve casing. The opening/closing unit is one interlocked integral comprising a shaft with cam and matching with steel balls on two valve butterflies and a pulling rod connecting the two valve butterflies. The sealing unit is one planar sealing structure. The cam on the rotating shaft applies the opening or closing force directly onto the steel balls of the valve butterflies, with the magnitude of the force being regulated automatically with the spring on the valve butterflies, and the sealing part has small contact are with the valve seat, acted force, high sealing performance and long service life.
Description
Technical field
The present invention relates to a kind of valve, suit in the pipeline of the important device of industries such as oil, chemical industry, generating connects the Planar Seal Three-Way Valve of installing and using especially.
Background technique
Used three-way valve in the pipeline of existing every profession and trade important device, its unlatching, close, seal arrangement all adopts butterfly valve or ball-valve structure, be shaped as the not only difficult processing of curved surface, and also require the machining accuracy height, especially the required precision of cooperation place is higher, and sealing surface is directly stressed, Sealing is fragile, working life is short, needs often transposing, has increased the trouble of working strength of workers and maintenance.
Summary of the invention
Technical problem to be solved by this invention is: a kind of Planar Seal Three-Way Valve is provided, adopts plane sealing structure, it is simple in structure, easily processing, and processing cost is low, and sealing load can be regulated automatically, and seal durability is long, good airproof performance.
The present invention addresses the above problem the technological scheme that is adopted: Planar Seal Three-Way Valve is by in the valve casing that has adapter, loam cake, lower cover, be connected with seal arrangement, open and close control valve unit and constitute, described seal arrangement connects to form valve setting by butterfly plate that spring, steel ball, Sealing are installed and pressing plate, respectively be fixed on valve casing on valve seat cooperate formation, described keying control valve unit is that the axle that has cam in the valve casing cooperates with steel ball on two valve settings respectively, and two valve settings is connected into a whole formation of linkage with pull bar.
Compared with prior art, the invention has the advantages that: this valve cooperates the keying control valve unit of formation and cooperates the flat seal that constitutes with valve seat by Sealing protruding on the valve setting plane because of adopting valve setting with cam, it is simple in structure, and cam, the easy installation and processing of valve setting, processing, quality of fit is less demanding, cam is applied to power on the steel ball of valve setting when opening and closing valve, the big I of power is regulated automatically by spring, make the surface of contact of Sealing on the valve disc plane and valve seat big and stressed little, thereby reduce the distortion and the wearing and tearing of Sealing, prolonged working life greatly, good airproof performance.

Embodiment
Embodiment is further described the present invention below in conjunction with accompanying drawing.
Butterfly plate 10 is a shape, bottom periphery has the screw of two correspondences, the waist shape blind hole that the bottom lower surface edge has two correspondences and communicates with screw, there is a groove centre, one blind hole is arranged in the middle of the groove, it is step-like ring groove and screw that upper base surface has a cross section, cast rubber material in the ring groove, produce the Sealing 18 that exceeds groove, in butterfly plate 10 blind holes, pack into stage clip 20 and steel ball 19, and with the middle pressing plate 17 that bellmouth orifice is arranged, be screwed in the groove of butterfly plate 10 lower surfaces, make steel ball can from butterfly plate 10, not drop out the formation valve setting, as shown in Figure 3.
The threeway valve casing of valve casing 6 for there being three to take over 12, three valve ports, bottom are screwed the middle lower cover 14 that blind hole is arranged.
Valve seat 11 is tubular for the centre, and three supporting ribs and fan-shaped pylone, peripheral reeded circle are arranged on the bottom surface.
Peripheral groove is embedded with the valve seat 11 of seal ring 8, be weldingly fixed in 6 liang of correspondences of valve casing and two adapters 12 in a straight line, two valve settings respectively with valve seat 11 on pore be slidingly matched, and the screw 9 of opening arranged with an end, be clamped on the supporting rib of valve seat 11, screw 9 end in addition is fixed in the screw of butterfly plate 10 upper surfaces with screw thread on it, whole valve setting is hung the jail can not rotate it, can only do a left side along screw 9 and supporting rib, moving of right, again the two ends of two pull bars 15 are inserted in the waist shape blind hole of butterfly plate 10 lower surfaces respectively, and with screw by screw on the butterfly plate 10 with its firm fixation on butterfly plate 10, an integral body that two valve settings is connected into linkage is the interlock body, asks as Fig. 2.
Axle is connected with seal ring 3 and plane bearing 4 on 2, and with pin cam 13 is fixed on the axle 2, and the axle 2 that assembles is inserted in the middle of two valve settings, in the blind hole on the lower end insertion lower cover 14 of axle 2, and can rotate in blind hole.
Pointer 1 is used screw, locating pin 5 usefulness on it screw thread be separately fixed on the neutral position of loam cake 7, the loam cake 7 that assembles is screwed on an end face of valve casing 6, and axle 2 ends pass the through hole on loam cake 7 and the pointer 1, stretch out outside the loam cake 7 and be convenient to be operatively connected, as shown in Figure 1.
During use, flowing medium is taken over 12 from the valve port on valve casing 6 one sidewalls and is flowed into, and valve casing 6 left side valve ports are closed, and fluid flows out through adapter 12 places of valve casing 6 the right valve ports, as shown in Figure 1, 2.
If will change the flow direction of flowing medium, rotatingshaft 2 makes it rotate 180 °, allow the cam 13 of axle on 2 forward on the location right from the left side, and the steel ball 19 on the valve setting on the right of withstanding, promoting valve setting simultaneously moves right, make Sealing 18 on the valve setting be close to the right and take over a valve seat 11 on 12, play and close, seal action, simultaneously under the effect of pull bar 15, make the left side valve disc interlock body that links together with the right valve setting, parallel moving right opened a valve port on the valve casing left side synchronously, fluid is taken over 12 from valve casing 6 one sidewall valve ports and is flowed into, and takes over 12 from valve casing 6 left side valve ports and flows out the commutation effect of playing.(figure does not draw)
