Abstract
The utility model relates to a novel automatic oil choking water drain valve, which belongs to the improvement on an oil choking water drain valve of the petrochemical industry. The utility model utilizes the principle of the medium density difference between two liquids to control the opening and closing of the valve, and achieves sealing and full automatic control of the mechanical self force type of the liquid drain. The utility model has no need of any power supply or an electric device. The utility model is mainly composed of a limit valve cover (1), a float valve, a liquid drain opening fixing cap (3) and a liquid drain pipe (5).
Description
The utility model relates to a kind of novel automatic oil resistance drain valve, and it is the improvement that belongs to the oil resistance water discharging valve in the petrochemical industry.It is to have utilized the principle of the Media density difference between two kinds of liquid to control the open and close of float valve, thereby reaches the automatic control of sealing and discharge opeing.It mainly is to be made of spacing valve bonnet (1), float valve, liquid port locking cap (3) and liquid-discharging tube (5).
In many processes of petrochemical industry, oil movement and storage, the automatic separation of profit and the means of eliminating are very important safety measures.As the oil resistance drain valve that stores in the fire-dike of storage tank field of oil and products thereof is exactly one of them, the effect of this drain valve is exactly: when oil storage tank takes place to run oil, fire-dike can be limited in oil in the fire-dike, and its oil is not outflowed and prevent contingent fire spread, the oil resistance drain valve of this moment cuts out; But when usual raining, then to open this valve in time, so that the rainwater in the fire-dike is in time discharged.At present, countries in the world all are to adopt manual drainage to control the discharge of rainwater, have arranged behind the rainwater manual-lock drain valve again.In petrochemical plant and in the gun barrel in oil field, also adopt similar manual drainage valve to realize the purpose of oil resistance draining often.The shortcoming of this manual drainage valve, the one, troublesome poeration, because as long as rain or other reason think draining, just must remove switch valve manually in time, otherwise rainwater may cause to the corrosion of tank bottom with to the oily fire of contingent race and constitutes floating excessive threat; The 2nd, dangerous, because the drain valve of present fire-dike is Chang Kai or normal closing, what have does not simply have drain valve and lets alone free draining, thus oil run out of the situation of fire-dike and happen occasionally, to around facility and personnel work the mischief; The 3rd, in case take place to run oil, then both caused any property loss, again environment and ecology is on every side polluted.Therefore, design the automatic valve of oil resistance draining automatically, make it be issued to self-draining purpose in operatorless situation, be that the oil worker explores and studies always.
The utility model purpose provides a kind of automatic oil resistance drain valve with regard to being to avoid above-mentioned deficiency of the prior art, and it is to utilize the open and close of the density difference control float valve of oil product and water to realize the function of oil resistance draining.It mainly is to be made of spacing valve bonnet (1), float valve, liquid port locking cap (3) and liquid-discharging tube (5), its major technology key is to be provided with liquid port locking cap (3) in liquid-discharging tube (5) inlet, and float valve being set in the upper end of locking cap (3), the arranged outside of its float valve (2) has the upper spacing valve bonnet (1) of the float valve of qualification.
Accompanying drawing 1 is the structural representation that the utility model is not provided with the counterweight float valve.
Accompanying drawing 2 is the structural representation that the utility model is provided with the counterweight float valve.
In order to realize better above-mentioned advantage of the present utility model, designer of the present utility model then is designed to be float valve by hollow float valve (2) and counterweight float valve (8) and is formed, and its hollow float valve (2) is internal diameter greater than leakage fluid dram locking cap (3) external diameter, top shutoff, with the hollow cylinder of sealing annular space; Its counterweight float valve (8) be internal diameter greater than hollow float valve (2) external diameter, the top is with the radial support body and with the hollow cylinder of sealing annular space; The import department of its discharging tube (5) is provided with leakage fluid dram locking cap (2), the internal diameter of this locking cap (2) is greater than the external diameter of discharging tube (5), and be fixed on the outer wall of discharging tube (5) with supporting rib (4), be provided with ring packing limited block (6) in the lower end of discharging tube locking cap (3), the diameter of its position limiting sealed piece (6) is greater than the internal diameter of hollow float valve (2); The internal diameter of its spacing valve bonnet (1) is greater than the external diameter of float valve, and its top offers intercommunicating pore (9), its lower end be fixed on diametral rib discharging tube (5) sealing limited block (6) below, filter screen (7) is set simultaneously diametrically.
Come enumeration structural feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, two kinds of then float valve being designed to have the counterweight float valve and not having the counterweight float valve according to the density of different oil products of artificer of the present utility model.Like this, be the mouth of pipe place that the locking cap of the discharge opeing mouth of pipe is fixed on liquid-discharging tube by rib in the mill, an annular stop piece that the hollow float valve that seals and limit is the next is set in its following a distance, hollow float valve (the density size of looking oil product determines whether to dispose the counterweight float valve) is set outside its locking cap, and the lower end of hollow float valve can be dropped on down on the sealing limiting stopper; One of outer arrangement at float valve simultaneously plays the upper spacing valve bonnet of qualification float valve, and the top of this valve bonnet also has intercommunicating pore; Cause obstruction for preventing that foreign material enter liquid-discharging tube in the process of draining, the artificer also is provided with screen cloth in the lower end of spacing valve bonnet.When this automatic oil resistance drain valve is worked, utilize the principle of the Media density difference of two kinds of liquid, float valve is floated, the big liquid of below density this moment is then discharged along the discharge opeing mouth of pipe, when being discharged to, discharge opeing make float valve fall to the sealing limiting stopper and when sealing up the mouth of pipe, the liquid that density is little then is stopped in outside the valve.Simultaneously, because the special construction of locking cap makes the utility model overcome the dirty vortex pumping action that produces of straight tube, this also is one of characteristics of liquid outlet of the present utility model.
Of the present utility model simple in structure, reasonable in design, without any need for power supply or electrical part, be the full automatic working of mechanical self-powering type fully, and cheap for manufacturing cost, easy for installation, have the advantage that manual liquid discharging valve can't be compared.The accumulating that it not only can be used for oil with collection defeated in, but also can use widely in the storage tank of light-end products and chemical product in the petrochemical industry.
