Preferably, the first sealing ring lip is arranged towards the inside.
Preferably, the second sealing ring lip is arranged towards the outside.
Preferably, the sealing device further comprises a limiting strip, wherein the limiting strip is arranged between the first sealing plate and the second sealing plate, and is arranged at the upper end of the flashboard.
Preferably, the sealing device further comprises a bolt, and the limiting strip is connected with the first sealing plate and the second sealing plate through the bolt in a fastening mode.
Compared with the prior art, the utility model has the advantages of it is following:
the utility model discloses a closing plate respectively has two seal grooves about three one-way valves, puts two sets of sealing washers, and wherein, the sealed slurry that is in the sealed valve pocket of oval groove can not leak in four directions from controlling closing plate and flashboard formation valve body, and the sealed pipeline of circular seal groove middle and high pressure side ore pulp is not to the low pressure side leakage.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples, which are not intended to limit the present invention.
As shown in fig. 1 to 3, the embodiment of the utility model discloses an including the valve body and the hoist mechanism 1 of setting at the valve body front end, be provided with flashboard 2 in the valve body, flashboard 2 upper end is connected with hoist mechanism 1, still be provided with seal structure on the valve body, seal structure includes closing plate and seal groove, the closing plate includes first closing plate 3 and second closing plate 4, the seal groove includes first seal groove 5 and second seal groove 6, first closing plate 3 and second closing plate 4 set up both ends about the valve body respectively, first seal groove 5 sets up at the front end of closing plate and first seal groove 5 is circular structure, second seal groove 6 sets up at the rear end of closing plate and second seal groove 6 is oval structure, be provided with first sealing washer in the first seal groove 5, be provided with the second sealing washer in the second seal groove 6. The first sealing ring is a KY-type sealing ring, and the lip edge of the first sealing ring faces the inner side. The second sealing ring is a 0-shaped sealing ring or a KY-shaped sealing ring, and the lip edge of the second sealing ring faces the outer side. Spacing strip 7 sets up between first closing plate 3 and second closing plate 4 to spacing strip 7 sets up the upper end at flashboard 2, and spacing strip 7 is through bolt and first closing plate 3 and the even fastening connection of second closing plate 4. The height of the gate plate 2 and the limiting strip 7 between the first sealing plate 3 and the second sealing plate 4 is ensured to be 20.03 mm higher than the gate plate.
The specific implementation method comprises the following steps: the 0-type sealing ring is placed in a second sealing groove 6 of the first sealing plate 3 and the second sealing plate 4, the KY-type sealing ring at the inner lip edge is placed in a first sealing groove 5, the KY-type sealing ring at the outer lip edge is placed in the first sealing groove 5, the limiting strip 7 is placed between the first sealing plate 3 and the second sealing plate 4, the flashboard 2 is placed between the limiting strips 7, the first sealing plate 3, the second sealing plate 4 and the limiting strips 7 are fastened through bolts 8, and the flashboard 2 is connected with the lifting mechanism 1 through a trapezoid groove.
The working principle of the embodiment is as follows: in the circular sealing groove of the one-way three-piece valve, a sealing plate with a KY-type sealing ring lip edge facing the inner side is connected with a high-pressure end pipeline correspondingly, and a sealing plate with a KY-type sealing ring lip edge facing the outer side is connected with a low-pressure end pipeline correspondingly. When the one-way three-piece valve is opened, the valve is a section of short pipe, when the one-way three-piece valve is closed, ore pulp on a high-pressure side is sealed by virtue of the KY-type sealing ring with the lip edge facing inwards, the ore pulp cannot enter a valve cavity formed by the two sealing plates, so that sealing is realized, once the KY-type sealing ring with the lip edge facing inwards is damaged, the ore pulp enters the valve cavity, but the lip edge of the KY-type sealing ring on the other side faces outwards, the ore pulp in the valve cavity of the one-way three-piece valve is sealed, and the ore pulp cannot enter a pipeline on a low-pressure side.
In the past, three valves can be used in two directions, once the three valves are installed, ore pulp flows in a single direction, and the sealing structure on the other side has no significance. In this embodiment, one-way three-piece valve changes seal structure through making clear of high-low pressure installation direction, and the KY type sealing washer of placing in the circular seal groove on the closing plate, the inside KY type sealing washer of lip limit is placed to one side, and the outside KY type sealing washer of lip limit is placed to one side, realizes dual seal, and in case one side is sealed to be damaged, the opposite side still can be realized sealing, and its life can improve nearly one time.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
