The utility model discloses a material leakage prevention device for a flap valve used for closing the gap between the rotation shaft of the turnover panel and its copper sleeve. The tight ring and the sealing sleeve are fixedly connected with the valve body through welding seams. The sealing sleeve is provided with an annular groove, and the sealing packing matching the outer circle of the turning shaft of the flap is arranged in the annular convex groove. The sealing packing is pressed and fixed by the pressing ring. In the annular groove, the compression ring is connected to the sealing sleeve through bolts, and the leak-prone gap is blocked by the sealing packing in the annular groove on the sealing sleeve, thereby reducing the occurrence of leakage accidents. The air port, through the air inlet, the input pressure is higher than the gas inside the valve body to avoid leakage, which is conducive to saving costs, ensuring production safety and protecting the environment, and can be used for leak-proof transformation of flap valves.
Description
Technical field
The utility model relates to a kind of application accessory of Flap valve, especially a kind of Flap valve leakage-proof material device.
Background technique
At present, Flap valve is widely used in pipeline transport control.Usually, the pipeline of installation Flap valve is to be used to carry fluidized material.When the internal pressure of pipeline is higher than barometric pressure, will cause the gap location ejection between the copper sheathing of a large amount of fluidized materials on turnover panel rotating shaft and the valve body, material is depleted, and environment is contaminated, if the scald accident also very easily takes place high-temperature fluidizedization material.
The model utility content
Be prone to deficiency in order to overcome existing Flap valve in turnover panel rotating shaft and the generation leakage of copper sheathing cooperation place; The utility model technical problem to be solved provides a kind of Flap valve leakage-proof material device; Be used to seal the gap between turnover panel rotating shaft and its copper sheathing, thereby reduce the generation of leakage accident.
The utility model solves the technological scheme that its technical problem adopted: Flap valve leakage-proof material device; Comprise and be positioned at the valve body outside and be socketed in stuffing box gland and the hold-down ring in the turnover panel rotating shaft; Stuffing box gland is fixedly connected with valve body through weld seam; Stuffing box gland is provided with annular groove, is provided with the stuffing box packing that cooperates with turnover panel rotating shaft cylindrical in the annular tongue, and the compacted ring of stuffing box packing is fixed in said annular groove.
Said hold-down ring is connected with stuffing box gland through bolt.
Said stuffing box gland is provided with suction port, and the inner of suction port is communicated with following gap, and this gap axis is between valve body and stuffing box packing, radially between turnover panel rotating shaft and stuffing box gland.
The beneficial effect of the utility model is: through outside valve body, setting up stuffing box gland and the hold-down ring that is socketed in the turnover panel rotating shaft; Make the gap between the copper sheathing on turnover panel rotating shaft and the valve body be positioned at the stuffing box packing shutoff in the annular groove on the stuffing box gland; Thereby reduce the leakage of material, suction port further is set on stuffing box gland, be higher than the gas of valve inner through the suction port incoming pressure; Avoid the generation of leaking; Help practicing thrift cost, ensure production safety and protection environment, can be used for the leakproof transformation of Flap valve.
Description of drawings
Fig. 1 is the schematic representation of existing Flap valve rotating shaft place structure.
Fig. 2 is the utility model Flap valve leakage-proof material schematic representation of apparatus.
Be labeled as 1-valve body, 2-copper sheathing, the rotating shaft of 3-turnover panel, 4-stuffing box gland, 5-stuffing box packing, 6-hold-down ring, 7-bolt, 8-suction port, 9-valve inner, 11-weld seam, 41-annular groove among the figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the turnover panel rotating shaft 3 of existing Flap valve cooperates with copper sheathing 2 on the valve body 1, after long-term the use; Copper sheathing 2 wearing and tearing; Gap between turnover panel rotating shaft 3 and the copper sheathing 2 is strengthened, and when the internal pressure of pipeline is higher than barometric pressure, will cause a large amount of fluidized materials to spray from the gap location between turnover panel rotating shaft 3 and the copper sheathing 2; Material is depleted, and environment is contaminated.
As shown in Figure 2, the Flap valve leakage-proof material device of the utility model comprises that to be positioned at valve body 1 outside and be socketed in the stuffing box gland 4 and hold-down ring 6 in the turnover panel rotating shaft 3, and stuffing box gland 4 is fixedly connected with valve body 1 through weld seam 11; Said weld seam 11 can prevent that material from spilling from the gap between stuffing box gland 4 and the valve body 1; Stuffing box gland 4 is provided with annular groove 41, is provided with the stuffing box packing 5 that cooperates with the cylindrical of turnover panel rotating shaft 3 in the annular tongue 41, and stuffing box packing 5 compacted rings 6 are fixed in said annular groove 41; Stuffing box packing 5 deforms under pressure; It closely contacts with the cylindrical of turnover panel rotating shaft 3 and the inwall of annular groove 41, shutoff the gap between turnover panel rotating shaft 3 and the copper sheathing 2, when stuffing box packing 5 wearing and tearing, can change; Thereby can greatly reduce the leakage of material, avoid environmental pollution.
As shown in Figure 2, said hold-down ring 6 is connected with stuffing box gland 4 through bolt 7, is convenient for changing stuffing box packing 5, also is convenient to adjust the impacting force of hold-down ring 6.
As shown in Figure 2, preferably be provided with suction port 8 on the said stuffing box gland 4, the inner of suction port 8 is communicated with following gap; This gap axis is between valve body 1 and stuffing box packing 5; Radially between turnover panel rotating shaft 3 and stuffing box gland 4,, can said suction port 8 be connected with pressurization-gas cascade through pipeline for the demanding occasion of leakage-proof material; Make the pressure in the said pressurization-gas cascade be higher than the pressure in the valve inner 9, strengthen sealing effect with hermetic seal.
