Detailed description of the invention
In order to be better understood by the purpose of this utility model, structure and function, below in conjunction with the accompanying drawings, to this
A kind of dibit of utility model seals valve and does further detailed description.
As shown in Figures 2 and 3, dibit of the present utility model sealing valve includes valve body 1 and valve plate 2, valve
It is provided with pressure head 3 on body 1, valve plate 2 is provided with sealing ring 4, the pressure head 3 on valve body 1 and valve plate
Sealing ring 4 on 2 is oppositely arranged and contacts with each other, to realize sealing.Wherein, valve plate 2 is provided with
Trim ring 5, trim ring 5 is removably disposed on valve plate 2 (being to be bolted in the present embodiment),
Trim ring 5 contacts with sealing ring 4, to be fixed on valve plate 2 by sealing ring 4.
Further, the bottom of valve plate 2 is provided with bearing pin 6, and bearing pin 6 has the top of dome shape, valve plate
Groove 7 (being preferably placed at the central position of valve plate 2), the sphere of bearing pin 6 it is formed with on the bottom surface of 2
Shape top is contained in the groove 7 on valve plate 2 bottom surface, and valve plate 2 is at the work on the dome shape top of bearing pin 6
Under with, there is rotary freedom, valve plate 2 and pressure head 3 automatic centering on valve body 1 can be made.Wherein, valve
Groove 7 on plate 2 bottom surface can be provided with wear-resistant pad 8, the dome shape top of bearing pin 6 and wear-resistant pad 8
Contact, to avoid the dome shape top of bearing pin 6 directly to contact friction with valve plate 2, extend bearing pin 6
Service life and avoid valve plate 2 impaired.
Further, the opening part of the groove 7 on valve plate 2 bottom surface is provided with end cap 9, the opening of end cap 9
Diameter is less than the diameter on the dome shape top of bearing pin 6, so that the dome shape top of bearing pin 6 is limited in valve plate
In groove 7 on 2 bottom surfaces.Wherein, groove 7, end cap 9 and the company of bearing pin 6 on valve plate 2 bottom surface
The place of connecing can be provided with silicone rubber pad 10, to avoid the contact friction between end cap 9, bearing pin 6 and valve plate 2,
Extend the service life of bearing pin 6 and avoid valve plate 2 impaired.
Further, the bottom of valve plate 2 be provided with lever 11, lever 11 and valve plate 2 be parallel to each other and
Every setting, the bottom of bearing pin 6 is through lever 11 and connects with nut 12, with by lever 11 and valve plate
2 link together.Wherein, on lever 11, surrounding along bearing pin 6 is evenly arranged with many tops 13 (this
Embodiment is provided with four), top 13 is extended towards valve plate 2, the end of top 13 and valve
There is between the bottom surface of plate 2 degree of freedom and limit gap, to limit the rotary freedom of valve plate 2.It should be noted that
, the degree of freedom restriction gap between end and the bottom surface of valve plate 2 of top 13 can be 1-3mm,
It is preferably 2mm.
Thus, the valve plate 2 in this utility model is arranged on the sphere top of bearing pin 6 so that valve plate 2 has
There are two rotary freedoms, and by the limit degree of freedom of four tops 13 restriction valve plate 2 on lever 11
Scope, when sealing valve and closing, valve plate 2 can automatic and pressure head 3 centering, the sealing ring 4 on valve plate 2
Being in close contact with pressure head 3, sealing ring 4 is not by tangential force, and service life is long, good airproof performance.
As shown in Figure 2 and Figure 4, the lever 11 in this utility model is connected with connecting rod 14, connecting rod 14
On be provided with work and connect position 15 and maintenance connects position 16, hydraulic cylinder 17 can respectively with on connecting rod 14
Work connection position 15 or maintenance connect position 16 and are connected, to realize the normally-open of valve plate 2 or maintenance unlatching.
Wherein, between work connection position 15 and the maintenance connection position 16 on connecting rod 14, there is maintenance angle, dimension
Repair angle and can be 30 °-50 °, preferably 40 °.
Thus, when the sealing valve in this utility model normally works, the homalocephalus of hydraulic cylinder 17 and connecting rod 14
Work connect position 15 connect, the opening and closing angle of valve plate 2 is 95 °；When maintenance, valve plate 2 is first beaten
Reaching 95 °, the homalocephalus taking out hydraulic cylinder 17 is connected the connection bearing pin of position 15 with the work of connecting rod 14,
Allow oil cylinder reach maintenance again and connect position 16, connect the homalocephalus of hydraulic cylinder 17 and connecting rod 14 with bearing pin
Maintenance connects position 16, hydraulic cylinder 17 rod chamber oil supply, and oil cylinder is retracted, and valve plate 2 can be opened to 135 °,
So maintainer is just without changing sealing ring inside head tank, and only need to stand in just can be fast outside upper sealing valve
Speed is changed.
Dibit of the present utility model seals valve by ball stud shaft design, makes the valve plate when closed can be automatic
Centering, sealing ring and pressure head can tightly contact, and sealing ring by tangential force, does not improves the close of upper sealing valve
Sealing property also extends use time of sealing ring.Meanwhile, valve plate can be opened to the outside of general overhaul door,
Maintainer stands in the replacing that just can carry out sealing ring outside equipment, shortens the time of maintenance, improves
The safety of work, reduces labor intensity.
By specific embodiment, this utility model is further described above, it should be appreciated that
It is, the most concrete description, should not be construed as the restriction to spirit and scope of the present utility model, ability
