Specific embodiment

For make the above-mentioned purpose of the utility model, feature and a little can become apparent it is understandable, with reference to the accompanying drawing to this Invention is further described in detail, and embodiments given below is only for illustrating the utility model, rather than in order to limit The scope of the utility model.

In the description of the present invention, it should be noted that the orientation of the instructions such as term "front", "rear", "left", "right" Or positional relationship, it is the utility model and to simplify description, rather than the device or member of indication or suggestion meaning for ease of description Part must have specific direction, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention. Wherein, the position by the first valve body with respect to the second valve body, is defined as " preceding ".In addition, term " first ", " second " etc. are only used for retouching Purpose is stated, cannot be understood as indicating or implying relative importance.

As shown in Figs. 1-2, a kind of hydraulic drive high-temperature blank-plate valve, including gantry support 1, valve body, valve plate 4, carry mechanism 5, stretch Contracting set 6, locking drive mechanism 7.

The valve body include the first valve body 2, the second valve body 3,3 correspondence of first valve body 2 and the second valve body it is solid Dingan County is on gantry support 1, position of the valve plate 4 between the first valve body 2 and the second valve body 3, and passes through carry machine Structure 5 is hung on gantry support 1.

1 upper end of gantry support be equipped with upper rail compatible with carry mechanism 5, lower end be equipped with it is compatible with valve plate 4 under Guide rail, carry mechanism 5 can slide along upper rail, and valve plate 4 or so is guided to slide together with lower guideway, and inlet-outlet valve body realizes valve Open and close.

6 front end of telescopic is corresponding with the first valve body 2, and rear end is protruded into the second valve body 3, with 3 inner wall of the second valve body Sealing sliding cooperation；The locking drive mechanism 7 is drivingly connected telescopic 6, can drive telescopic 6 before 3 axial direction of the second valve body Afterwards toward polyslip.

When the valve is closed, valve plate 4 is located in valve body, and locking drive mechanism 7 drives telescopic 6 to compress valve plate 4, so that valve 4 front side of plate is sealed with the first valve body 2, and rear side and telescopic 6 seal.

When valve needs to open, locking drive mechanism 7 drives contracting set 6 to move backward, and separates with valve plate 4, then passes through Valve plate 4 is moved to outside valve body by carry mechanism 5, and last locking drive mechanism 7 drives telescopic 6 to move forward again, makes to stretch Set 6 is fitted closely with the first valve body 2, realizes sealing.

When valve needs to close, locking drive mechanism 7 drives telescopic 6 to move backward, and separates with the first valve body 2, and The space entered for valve body 4 is reserved, valve plate 4 is then moved by valve inner by carry mechanism 5, finally locking driving Mechanism 7 drives telescopic 6 to move forward again, and telescopic 6 and valve plate 4 is made to compress valve plate 4, so that 4 front side of valve plate and the first valve body 2 Sealing, rear side and telescopic 6 seal.

Using the above structure, valve plate can be made to omit the structure of deflector hole, valve plate is made to be always positioned at the side of valve body, it is right There is no space requirement in the other side of valve body, the left side or the right can be set by in-site installation spatial choice, compared with blank-plate valve, Volume is smaller, reduces occupied space, more practical.

It is provided with hydraulic station in the present embodiment, carry mechanism 5 and locking drive mechanism 7 are all made of hydraulic driving side Formula runs smoothly.

Wherein, locking drive mechanism 7 is equipped with multiple, and is circumferentially uniformly mounted to the second valve body 3, and telescopic 6 passes through lock Tight driving mechanism 7 automatically controls, and compared with existing machinery formula locking device, operation is more convenient, and time saving and energy saving, synchronism is more It is good, be not in the problems such as card relates to, and can sealing force caused by, external force poor according to compensation temperature etc. deficiency, realization is close Envelope compensation, sealing performance are more preferable.

In addition, energy storage canister energy storage can be used, ftercompction can be started automatically after system pressure drops to setting pressure, it is ensured that hair Sealing force needed for bright sealing is realized long-term non-maintaining.

Certainly, other automatic driving methods such as screw rod, cylinder can also be used with locking drive mechanism 7 in the carry mechanism 5.

As shown, the rear end face of first valve body 2 is equipped with two layer of first sealing ring 8, the front end of the telescopic 6 Face is equipped with two layer of second sealing ring 9, two layers of sealing ring, the sealing ring of multilayered structure is certainly not limited to, so that sealing effect is more It is good.

First sealing ring 8 and the second sealing ring 9 can be using materials such as rubber, graphite, it is preferred that can select stone Ink material, can have better high temperature resistance in this way, and temperature use scope is bigger.

In addition, first sealing ring 8 is mutually staggered with the second sealing ring 9, it is ensured that work as valve opening, the first valve body 2 with When telescopic 6 is bonded to each other sealing, it can guarantee the sealing effect of the first sealing ring 8 and the second sealing ring 9.

As shown, the rear end of second valve body 3 is additionally provided with creeping flange 10,10 front end of creeping flange protrudes into In two valve bodies 3, sliding cooperation is sealed with 3 inner wall of the second valve body, rear end forms connecting flange.It is sliding by the front and back of creeping flange 10 It moves, not only facilitates installation, but also pipeline connection can be better adapted to, according to the installation space of different pipelines, can be adjusted It reorganizes and brings up to full strength and repays, the scope of application is higher.

It is of course also possible to be that creeping flange is arranged in the front end of the first valve body 2.

As shown, second valve body 3 is equipped with first annular positive stop lug boss 31, the telescopic by the inner wall of front end 6 and second are equipped with the first airtight and watertight padding 11 between valve body 3, first airtight and watertight padding 11 by the first airtight and watertight padding gland 12 with First annular positive stop lug boss 31 is fixed；Inner wall of second valve body 3 close to rear end is equipped with the second annular stop boss 32, The second airtight and watertight padding 13 is equipped between the creeping flange 10 and the second valve body 3, second airtight and watertight padding 13 is close by second Envelope gland 14 is fixed with the second annular stop boss 32.

Guarantee the sealing effect between telescopic 6 and the second valve body 3 by the first airtight and watertight padding 11, passes through the second sealing Gland 14 guarantees the sealing effect between creeping flange 10 and the second valve body 3, guarantees sealing zero leakage.

Meanwhile it being filled out by the first airtight and watertight padding 11, convenient sealed to the first airtight and watertight padding 11, second of the second airtight and watertight padding 13 Material 13 is replaced.

Digital programmable control system can be used, joint-action mechanism is set, prevents maloperation, and can realize and a variety of remote collection The compatibility of middle control system.

Embodiment is not construed as the limitation to utility model, but any spiritual improvements introduced based on the utility model, It should all be within the protection scope of the utility model.
