Further, corrugated tube and end plate are also included；The second end and the end plate connection of v-shaped tube is stretched out in one end of stopper rod；Bellows-sheathed is located at outside the part stretching out the second end of stopper rod, and the two ends of corrugated tube respectively with the second end and end plate connection；Corrugated tube is configured to flexible with stopper rod back and forth movement.
Further, corrugated tube is by graphite grazing pad and first end and end plate connection.
Further, stopper rod is metal material.
Further, valve is V-type ball valve.
Further, stopper rod includes chock plug and bar portion, and chock plug mates with opening, and opening is circular or polygon, is provided with the second end opening at the second end, and the second end opening is stretched out in bar portion, and bar portion mates with the second end opening.
Further, the angle of v-shaped tube is 30-90 degree.The preferably angle of v-shaped tube is 60-90 degree.
This utility model also provides for a kind of equipment comprising discharging opening as above sealing structure.
Further, equipment is boiler, fermentation tank or blender.
Its beneficial effect:
(1) annexation of v-shaped tube, valve and stopper rod makes this discharging opening seal structure to there is two-layer and seal, and one be stopper rod, one for valve, it is achieved thereby that good seal during closedown, it is possible to seal material；During unlatching material want can smooth and easy fall；Close and open the purpose not affected by material.
(2) corrugated tube and end plate and annexation thereof make the control of stopper rod and seal more preferably.And corrugated tube is by graphite grazing pad and v-shaped tube and end plate connection, further ensure that sealing effectiveness, it is ensured that seal structure negative pressure state in whole application system, and graphite can be high temperature resistant.
(3) stopper rod is that metal material makes this discharging opening sealing structure be capable of withstanding high temperature.Temperature of charge in the material storing box of such as boiler is the highest, it would be desirable to be able to the discharging opening of tolerance high temperature seals structure.
(4) angle of v-shaped tube is 30-90 degree.The preferably angle of v-shaped tube is 60-90 degree.When this is conducive to opening, material is glided by deadweight.
(5) bar portion, the second end opening, bar portion stretches out the second end opening, and bar portion mates with the second end opening, and stopper rod and corrugated tube and the annexation of end plate so that stopper rod can straight line to left movement, fill in accurately at opening part, seal.
Accompanying drawing explanation
Fig. 1 is that the discharging opening that this utility model provides seals the detailed description of the invention of the structure internal structure schematic diagram when opening.
Fig. 2 be this utility model provide discharging opening seal structure a detailed description of the invention in off position time internal structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, this utility model is described in further detail.Should be understood that these embodiments this utility model solely for the purpose of illustration, rather than limit the scope of utility model by any way.
Embodiment one
As illustrated in fig. 1 and 2, the discharging opening that this utility model provides seals structure and includes v-shaped tube 1, stopper rod 3, corrugated tube 4, end plate 5 and V-type ball valve 6.The opening 11 of v-shaped tube 1 is arranged on its V tip location, and during work, the discharging opening coupling with the material storing box 2 needing the equipment sealed is connected.The first end 12 of v-shaped tube 1 is connected with V-type ball valve 6.One end of stopper rod 3 extend in the second end 13 of v-shaped tube 1, and the other end is exposed to outside v-shaped tube 1 be connected with end plate 5.Corrugated tube 4 is set in outside the part that stopper rod 3 exposes v-shaped tube 1.The two ends of corrugated tube 4 are connected by graphite grazing with the second end 13 and the end plate 5 of v-shaped tube 1 respectively.The chock plug 31 of stopper rod 3 mates closely sealed with opening 11.The cross section in the bar portion 32 of stopper rod 3 mates with the second end opening 131, and the second end opening 131 has certain thickness, it is ensured that can move along a straight line and be directed at opening 11 when stopper rod 3 promotes to the left and seal.The angle of V-type ball valve is 60 degree.This discharging opening seals structure and is mainly metal structure, and especially stopper rod is that refractory metal material is made.
Work process is: when stopper rod 3 shortens along with stopper rod 3 motion to left movement, corrugated tube 4, and when chock plug 31 arrives at opening 11, the material in material storing box 2 is sealed, and will not leak out, and now V-type ball valve 6 is also at closed mode, as shown in Figure 2；When stopper rod 3 moves right, and corrugated tube 4 moves elongated along with stopper rod 3, when chock plug 31 leaves opening 11, material in material storing box 2 slips down at V-type ball valve 6 due to deadweight along v-shaped tube, now V-type ball valve 6 is in opening, and material just flows out at V-type ball valve 6, as shown in Figure 1.Due to the existence of stopper rod 3, the switch seal of V-type ball valve 6 is not affected by material.
The Main Function of corrugated tube 4 and end plate 5 is to sealing gap that may be present between stopper rod 3 and the second end opening 131.The device driving stopper rod 3 to move can also be designed as by pulling end plate 5 to drive stopper rod 3 to move.
This discharging opening seals structure and carries out stopper rod 3 motion and the automatically controlling of V-type ball valve 6 folding also by connecting automation equipment.
This discharging opening seals structure and may be used in plurality of devices, various boiler such as such as retort etc..
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should be in the protection domain being defined in the patent claims.
