Abstract
The utility model relates to a boiler fuel leak test shunting device, into oil pipe oil feed fast valve is on the road managed, located including the female pipe of oil feed, oil return mother to, be equipped with the tubule footpath bypass of connecting in parallel in the oil feed fast valve on entering the oil pipe way, be equipped with the leak test fast valve in the tubule footpath bypass, tubule footpath bypass pipe diameter is lighter than the into pipe diameter on oil pipe way. The utility model provides a pair of boiler fuel leak test shunting device, through in the parallelly connected tubule footpath bypass in oil feed fast valve both ends, the oil pressure that appears in the time of can effectually avoiding boiler fuel leak test is undulant, simultaneously, the device simple structure arranges the convenience.
Description
Technical field
The utility model relates to field of thermal power, particularly relates to a kind of based on furnace fuel oil leak test shunting device.
Background technology
In the coal-burning boiler of thermal power plant, fuel system is the important component part of boiler.Due to the particularity of fuel oil, the safe operation of fuel system is very crucial.Will carry out fuel leakage test before boiler ignition start, object carries out pressure test to the flowmeter on fuel passage, valve, pipeline and some subsidiary pressure-containing members, and the load performance of inspection boiler oil system and tightness, ensure the reliably working of oil circuit.
In fuel leakage test, a wherein more crucial step is closedown oil return fast valve, opens oil-feed fast valve, punching oil is carried out to stokehold fuel system, then closes oil-feed fast valve, system tightness and bearing capacity between inspection oil-feed fast valve and oil return fast valve.But in existing coal-burning boiler, frequent multiple stage boiler shares a set of fuel system, open oil-feed fast valve in fuel system leak test when rushing oil to system, the oil pressure of fuel system there will be fluctuation, all forms adverse effect to facing stove, starting trouble and fuel pipe.In order to avoid there is this situation of pressure fluctuation in fuel leakage test, ensureing that constant pressure is constant, needing to take certain measure.In prior art, adopt the method increasing some equipment in the fuel system of routine configuration, realize constant pressure.
But carrying out in fuel leakage test, technique scheme can not ensure that fluctuation does not appear in oil pressure when oil-feed fast valve is opened.
Utility model content
The purpose of this utility model is to provide a kind of furnace fuel oil leak test shunting device, there will be the problem of fluctuation in order to solve oil pressure in existing furnace fuel oil leak test.
For achieving the above object, scheme of the present utility model comprises:
A kind of furnace fuel oil leak test shunting device, comprise oil-feed mother pipe, oil return mother pipe, the oil-feed fast valve be located on in-line, and, in-line is provided with the pipe with small pipe diameter bypass being parallel to oil-feed fast valve, pipe with small pipe diameter bypass is provided with leak test fast valve, and described pipe with small pipe diameter bypass caliber is less than the caliber of in-line.
Further, in described caliber bypass, be arranged in series at least one hand-operated valve with described leak test fast valve.
Further, the two ends of described leak test fast valve are respectively equipped with a hand-operated valve.
A kind of furnace fuel oil leak test shunting device that the utility model provides, by pipe with small pipe diameter bypass in parallel at oil-feed fast valve two ends, effectively can avoid the pressure fluctuation occurred during furnace fuel oil leak test; Meanwhile, this apparatus structure is simple, arrangement convenience.
Accompanying drawing explanation
Fig. 1 is embodiment 1 furnace fuel oil leak test shunting device schematic diagram;
Fig. 2 is embodiment 2 furnace fuel oil leak test shunting device schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Embodiment 1
As shown in Figure 1, furnace fuel oil leak test shunting device comprises the female pipe 2 of oil-feed, filter screen 3, oil-feed fast valve 10, each layer oil gun 11 of boiler, oil return pitch 9, flowmeter 8, oil return fast valve 7, oil return bus 1, and the pipe with small pipe diameter bypass in parallel with oil-feed fast valve 10; Pipe with small pipe diameter bypass is provided with test fast valve 5, and the caliber of pipe with small pipe diameter bypass is less than the caliber of in-line.
Fuel oil through two filter screens 3 of in-line set up in parallel, and then flows through oil-feed fast valve 10 and manually operated door, flowmeter etc., and then enters in each layer oil gun 11 of boiler after entering in-line from the female pipe of oil-feed; After fuel oil flows out from each layer oil gun, after flowing through oil return pitch 9, flowmeter 8, oil return fast valve 7 successively, enter oil return mother pipe.When oil-feed flows to oil-feed fast valve on in-line, can select to flow in each layer oil gun of boiler through oil-feed fast valve, also can select to flow in each layer oil gun after pipe with small pipe diameter bypass.
When carrying out fuel leakage test, close oil return fast valve 7, open test fast valve 5, punching oil is carried out to stokehold fuel system, now owing to no longer opening oil-feed fast valve when rushing oil, therefore avoiding in fuel system leak test and opening oil-feed fast valve system is carried out rushing oil and the oil pressure fluctuation that causes.
In the above-described embodiments, pipe with small pipe diameter bypass is connected in parallel on the two ends of the oil-feed fast valve assembly be made up of oil-feed fast valve, manually operated door, flowmeter, manually operated door, and as other embodiments, pipe with small pipe diameter bypass also can be directly parallel in the two ends of oil-feed fast valve.
Embodiment 2
As shown in Figure 2, be from the different of above-described embodiment 1, be respectively equipped with manually operated door 4 and manually operated door 6 at the two ends of leak test fast valve.
Before carrying out fuel leakage test, first open test manually operated door 4 and manually operated door 6; When carrying out fuel leakage test, close oil return fast valve 7, open test fast valve 5, punching oil is carried out to stokehold fuel system, now owing to no longer opening oil-feed fast valve when rushing oil, therefore avoiding in fuel system leak test and opening oil-feed fast valve system is carried out rushing oil and the oil pressure fluctuation that causes.
Be presented above the embodiment that the utility model is concrete, but the utility model is not limited to described embodiment.Under the thinking that the utility model provides; the mode easily expected to those skilled in the art is adopted to convert the technological means in above-described embodiment, replace, revise; and the effect played utility model object that is substantially identical with the relevant art means in the utility model, that realize is also substantially identical; the technical scheme of such formation is carried out fine setting to above-described embodiment and is formed, and this technical scheme still falls in protection domain of the present utility model.
