Abstract
The utility model relates to a crystallizer pressure testing device, and belongs to the technical field of smelting equipment in the metallurgical industry. According to the technical scheme, a crystallizer water tank (1) is communicated with a water diversion bag (11) through a water tank pipe (5), a water tank valve (7) is arranged on the water tank pipe (5), one end of a nozzle pipe (4) is communicated with the water diversion bag (11), a nozzle (3) is arranged at the other end of the nozzle pipe (4), a nozzle valve (6) is arranged on the nozzle pipe (4), and a water discharge pipe (2) is arranged on the crystallizer water tank (1). When a high-pressure pump is started, water enters the crystallizer water tank (1) through the water diversion bag (11), after the pressure reaches a set value, the high-pressure pump is stopped, pressure maintaining is carried out for a half hour, pressure testing is carried out on the nozzle (3) after the nozzle valve (6) is opened, and water discharge is carried out by opening a valve on the water discharge pipe (2) and a valve on an air inlet pipe after a pressure testing result is qualified. The crystallizer pressure testing device has the advantages of being simple in structure, convenient to operate and good in water discharge effect, saving the water resource, shortening the starting time of the high-pressure pump, reducing equipment accidents and guaranteeing normal production of steelmaking.
Description
Technical field
The utility model relates to a kind of crystallizer pressure testing device, belongs to metallurgy industry smelting equipment technical field.
Background technology
The metallurgy industry STEELMAKING PRODUCTION, plate slab crystallizer is the important component part of steelmaking continuous casting machines, whether the crystallizer of reorganizing and outfit all will carry out the water pressure test to it, checks that whether water tank and the water of spraying water is unobstructed, leak, to testing underproof will the processing in time, guarantee the integrity that crystallizer is reached the standard grade, if water tank or nozzle etc. are located to occur leaking, can cause bleed-out, crystallizer hydraulic pressure deficiency, molten steel in mold such as blows out at the serious accident.Owing in the cold weather water tank and in the nozzle pipeline, having ponding, cause the accidents such as crystallizer freezes winter, and impact is normally produced.
The utility model content
The utility model purpose is to provide a kind of crystallizer pressure testing device, at first to the pressurize of crystallizer water tank examination water, and then utilizes overbottom pressure to crystallizer nozzle examination water, reduces water discharge and high-pressure pump continuous operation, solves the problem existed in background technology.
The technical solution of the utility model is: a kind of crystallizer pressure testing device, comprise crystallizer water tank, drainpipe, nozzle, nozzle pipeline, water tank pipeline, nozzle valve, Cistern valve, Pressure gauge, air inlet pipe, main water inlet tube and Fen Shuibao, divide the water bag to be communicated with respectively Pressure gauge, air inlet pipe and main water inlet tube, crystallizer water tank and minute water bag are by the water tank pipeline connection, the water tank pipeline is provided with Cistern valve, nozzle pipeline one end is communicated with a minute water bag, the other end is provided with nozzle, the nozzle pipeline is provided with nozzle valve, and the crystallizer water tank is provided with drainpipe.
Be respectively equipped with valve on described air inlet pipe, main water inlet tube and drainpipe, nozzle is positioned at crystallizer water tank below.
When the crystallizer hydrostatic test, high-pressure pump starts, and water enters the crystallizer water tank through undue water bag, and after pressure reaches setting value, high-pressure pump cuts out, and closes the valve on main water inlet tube simultaneously.Pressurize half an hour, after the water pressure test is qualified, opens nozzle valve nozzle carried out to pressure testing, qualified after, valve and the valve on air inlet pipe opened on drainpipe carry out draining.
The beneficial effects of the utility model are: simple in structure, easy to operate, drainage effect is good, saves water resource, reduces the high-pressure pump opening time, has reduced equipment breakdown, has guaranteed the normal production of steel-making.
