Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
A two way sealed double eccentric butterfly valve sealing configuration peculiar to vessel as shown in Figure 1, this butterfly valve seal structure comprises: valve body 1, butterfly plate parts 2, stem member 3, a pair seal ring 4 and a pair seal ring pressing plate 5.
Wherein, valve body 1 inside is provided with a pair valve seal groove.Butterfly plate parts 2 have a pair circular surface, are arranged on middle part in valve body 1.Stem member 3 is arranged in valve body 1, in the middle part of butterfly plate parts 2, and is fixedly connected with these butterfly plate parts 2.Each seal ring 4 is nested with in valve seal groove corresponding in valve body 1; A pair seal ring pressing plate 5 is fixedly installed in valve body 1 respectively, and is compressed by the seal ring 4 of correspondence.
In the present invention, each seal ring 4 is O shape sealing configuration, and sealing circle 4 adopts the coated U-shaped rubber of the T-shaped stainless steel insert of liner to form O shape sealing configuration.Each seal ring pressing plate 5 is many tapped holes RunddichtringO pressing plate.In the present embodiment, each seal ring pressing plate 5 by fastening for the seal ring 4 of correspondence valve body 1 by hexagon socket cap head screw, is made seal ring pressing plate 5 compress corresponding seal ring 4, thus ensure that the sealing of high performance craft two way sealed double eccentric butterfly valve.
As Figure 1 and Figure 4, be provided with in valve body 1: the first valve rod hole 11, valve flowing channel 12.Wherein, valve flowing channel 12 is arranged in the middle part of valve body 1, and mutually through with the first valve rod hole 11.
As shown in Figure 1, butterfly plate parts 2 adopt pin 6 fixing with on the valve flowing channel 12 of valve body 1 inside.
In the present invention, valve body 1 is cast member, and the size of valve body 1 installs ANSIB16.34 standard and ANSIB16.5 standard makes.Valve body 1 is the most important support accessory of two way sealed double eccentric butterfly valve sealing configuration peculiar to vessel.
As shown in Figure 1, shown in Figure 5, butterfly plate parts 2 are arranged in valve flowing channel 12, are provided with the second valve rod hole 21 in the middle part of these butterfly plate parts 2.In the present invention, butterfly plate parts 2 are cast member.
As shown in Figure 4, stem member 3 comprises: valve rod 31, driving actuating device 32.Wherein, valve rod 31 is arranged in valve body 1 by the first valve rod hole 11; And inner through butterfly plate parts 2 by the second valve rod hole 21, and be fixedly connected with these butterfly plate parts 2.Drive actuating device 32 to be arranged on valve body 1 top, and be connected with valve rod.
As shown in Figure 3, actuating device 32 is driven to comprise: to drive power unit 321, handwheel 322.Handwheel 322 is connected with driving power unit 321, drives power unit 321 to be connected with valve rod 31.User is driven by handwheel 322 and drives power unit 321 to work, thus band ovable valve stem 31 rotates.
As shown in Figure 2, the sealing surface that each seal ring 4 is corresponding with valve body 1 forms the first sealing pair 41, and the spherical seal surface that sealing circle 4 is corresponding with butterfly plate parts 2 forms the second sealing pair 42.
In the present invention, the spherical seal surface that each seal ring 4 is corresponding with butterfly plate parts 2 forms the second sealing pair 42, can realize the seal action of high performance craft two way sealed double eccentric butterfly valve.
One disclosed by the invention two way sealed peculiar to vessel double eccentric butterfly valve sealing configuration specific works principle is as follows:
User is by handwheel 322 rotary actuation power unit 321, thus band ovable valve stem 31, butterfly plate parts 2 rotate freely within the scope of 90 °, makes butterfly plate parts 2 be in unlatching or closed condition.Thus reach the object switching on or off two way sealed double eccentric butterfly valve sealing configuration pipeline peculiar to vessel.When opening butterfly plate parts 2, in the valve flowing channel 12 of valve body 1, butterfly plate parts 2 rotate around valve rod 31 axis, and make the spherical seal surface of butterfly plate parts 2 depart from corresponding seal ring 4 gradually, when rotating arrival 90 °, butterfly plate parts 2 are in full open position.When closing butterfly plate parts 2, by the rotation of butterfly plate parts 2, the spherical seal surface of butterfly plate parts 2 moved closer to and extrudes corresponding seal ring 4, making it produce resiliently deformable and form elastic force as seal pressure, guarantee the sealability of two way sealed double eccentric butterfly valve sealing configuration peculiar to vessel.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
