Abstract
The utility model relates to an oil-block water drainage device. A seal disc seat with water drainage holes is fixedly arranged on a well opening, and the upper and the lower end surfaces of the seal disc seat are respectively fixed with a support frame and a flow guiding groove. A guide post is inserted in the support frame, and the lower end of the guide post contacts a fusing safety block which is arranged in the flow guiding groove. A float and a seal disc are respectively fixed on the guide post. When the fusing safety block meets oil and is fallen off, the guide post drives the seal disc and the float to move downwards. When the liquid surface in a fire bank reaches a critical height, the float drives the guide post and the seal disc to move upwards under the action of the flotage. Thereby, the utility model can automatically drain sewage under the normal conditions, and automatically prevent the petroleum product from leaking when accidental leakage occurs. The utility model keeps that the liquid surface is in a safe height, and avoids the overflow of the petroleum product.
Description
The utility model relates to-kind of oil resistance hydathode, belongs in the oil depot discharging fire-dike sewage and stops the oil product technical field that leaks.
At present oil depot generally adopts sewage in the movable metal baffle discharging fire-dike, and metal baffle is installed in sewage network well head in the fire-dike, and this baffle plate is in normally off at ordinary times, when in the fire-dike during sewage alluvial, draws back baffle plate, implements discharging.The drawback of its existence is: 1. metal baffle is operated the untimely reservoir area sewage alluvial that easily causes by manual operation.2. metal baffle is difficult for opening with the passing of time by corrosion gradually.3. in case oil product on fire overflows in the fire-dike, the fire fighting personnel can't carry out switching manipulation near baffle plate.4. the oil tank back oil product that breaks on fire is limited in the fire-dike, carrying out along with fire-fighting work, fire and cooling water system and foam mixing liquid conflux in a large number in fire-dike, liquid level constantly rises in the dike, if the interior fire-fighting waste water of dike this moment can not get timely discharging, to cause fire-fighting waste water that oil product is held up and overflow, fire is enlarged from fire-dike.
The purpose of this utility model is to provide a kind of oil resistance hydathode, and it can realize discharging automatically sewage in the fire-dike, stops oil product to leak automatically and is about to keep the interior liquid level of fire-dike in safe altitude when excessive when oil product in the fire-dike is on fire.
The purpose of this utility model is achieved in that
The seal disc seat of center band weep hole is installed on the blowdown well head.Seal disc seat lower end surface is fixed with guiding gutter.Seal disc seat upper-end surface is fixed with supporting frame.This supporting frame is made of the loam cake of support post and center band jack.The support post outer periphery is equipped with blocks dirty back-fire relief net.Directional post is inserted in the supporting frame, and both are slidingly matched.The lower end of directional post contacts with the molten molten safety block that is contained in the guiding gutter bottom, and is being supported by molten molten safety block.Be fixed with seal disc in supporting frame on the directional post, the sealing dish is corresponding with the middle weep hole of seal disc seat.Directional post top is fixed with float.Molten molten safety block is met water and is not reacted, and the support guide post is opened seal disc, and well head is in open mode, guarantees the normal discharging of sewage in the fire-dike; Molten molten safety block is met oil and is come off, and directional post loses the supporting drive seal disc and moves down, and seal disc is dropped in the central row water hole of seal disc seat, and well head is in closed state, stops oil product to flow into sewage network from well head; Be about to when excessive when oil product in the fire-dike is on fire, liquid level is in critical altitude, and the float that is fixed as one with directional post is subjected to floating function, drive on directional post and the seal disc and move, realize the discharging of fire-dike inner bottom part waste water, keep liquid level, avoid the excessive fire spread that makes of oil product in safe altitude.
The utility model has the advantages that simple in structure, easy to use.Automatically stop oil product to leak in the time of can realizing automatic sewage effluent, the accidental release under the normal condition and oil tank is on fire in putting out a fire to save life and property discharge of wastewater.Stop that flame enters sewage network in the fire-dike, stop outside sewerage network flame well head in the storehouse to enter the reservoir area.
Fig. 1 is the utility model structural representation.
Describe the utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the seal disc seat 11 of center band weep hole is fixedly mounted on the blowdown well head by stone bolt 12.Seal disc seat 11 lower end surfaces are fixed with guiding gutter 16, and molten molten safety block 13 is equipped with in the bottom of guiding gutter 16, and this safety block 13 can adopt pitch to make.The upper-end surface of seal disc seat 11 is fixed with supporting frame 7, and this supporting frame 7 is made of the upper end cap of support post and center band jack.The support post outer periphery is equipped with blocks dirty back-fire relief net 10.Directional post 4 is inserted in the supporting frame 7, and the lower end of directional post 4 contacts with molten molten safety block 13, and is being supported by molten molten safety block 13.Molten molten safety block 13 lower ends are provided with heat conduction steel wire 14.Seal disc 9 is fixed on the directional post 4 by limited ring 8, and sealing dish 9 is corresponding with the middle weep hole of seal disc seat 11.Float 5 is fixed on the top of directional post 4 by location clip 6, and two of directional post 4 is respectively equipped with stifled 2 and block up 15 down, and the top of directional post 4 also is provided with suspension ring 1 and screw 3.
Working procedure of the present utility model is such:
Molten molten safety block 13 is met water and is not reacted, and support guide post 4 is opened seal disc, and well head is in open mode, guarantees the normal discharging of sewage in the fire-dike; Molten molten safety block 13 is met oil and is come off, and directional post 4 loses supporting drive seal disc 9 and moves down, and seal disc 9 is dropped in the central row water hole of seal disc seat 11, and well head is in closed state, stops oil product to flow into sewage network from well head; Be about to when excessive when oil product in the fire-dike is on fire, liquid level is in critical altitude, and the float 5 that is fixed as one with directional post 4 is subjected to floating function, drive on directional post 4 and the seal disc 9 and move, realize the discharging of fire-dike inner bottom part waste water, keep liquid level, avoid the excessive fire spread that makes of oil product in safe altitude.
