Abstract
The utility model discloses an automatic air inlet/outlet valve for a double floatation hot water boiler, belonging to a safety accessory for a hot water boiler. A valve cover is arranged above a valve body. The inner part of the valve body is provided with a float ball, and the center part of the float ball is penetrated with a float rod. The upper and the lower parts of the float rod are respectively arranged in a guide plate and a guide sleeve movably. The guide sleeve is arranged at a center above the valve cover, and the inner part of the guide sleeve is movably provided with a slide plug. The center part of the slide plug is provided with an air outlet hole, and the outer circle of the lower end of the slide plug is formed into a cone. A sealing ring is arranged on a cone surface. The utility model has the advantages of reasonable structure, and reliable performance.
Description
The utility model relates to a kind of two unsteady hot-water boiler automatic air intake and discharge valve, belongs to the hot-water boiler safety attachment.
One of key of guaranteeing the hot-water boiler safe operation at present is to solve the escaping gas from water of boiler internal cause a variety of causes in the running in time to be discharged and timely air inlet when negative pressure occurring in some accidental cause boilers the balance inside and outside differential pressure.The conventional practice of above-mentioned exhaust, air inlet is to have closing valve to realize by fireman's manual operations, and it is reliable to be absolutely unsafe like this; The pipe laying automatic exhaust steam valve is also arranged, the hot-water boiler automatic air intake and discharge valve that this series products produces for Changchun Kuan Cheng on the current market, its primary structure is: valve casing is a basin shape, drive disk assembly is a float closing by a lever and a hinge aperture of control, this version easily causes the deposition of dirt in the valve pocket and fills up stifled and stuck operation parts, make the automatic vent performance malfunctioning, and there is the weakness that needs the air bleeding valve of installation varying number because of boiler capacity is different, hot-water boiler as a 1.4kw need be installed the 2-3 platform, and this will cause installation and maintenance inconvenience.Though also have a kind of twoport automatic air intake and discharge valve on the intake and exhaust problem, to solve the operating exhaust of hot-water boiler, air inlet problem on the current market, complex structure, the cost height, the cost of repairs is big.Exhaust gear comes off or malfunctioning phenomenon in case all may occur moving when transporting, load and unload or being subjected to vibrations big.Especially escaping gas is more after a little while in the hot water boiler system, water level is nearer apart from steam vent, the mechanism that the control steam vent opens and closes can not reset fully, often there is leakage phenomenon in this hole when system pressure is lower than 0.04Mpa, this corrodes on the one hand and washes away operation steam vent mechanism, cause the boiler body external corrosion on the other hand, bring inconvenience to the user.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of two unsteady hot-water boiler automatic air intake and discharge valve is provided, and it is simple in structure, the safety coefficient height, and cost is low, and result of use is good.
The purpose of this utility model is achieved in that
Valve gap is installed in the valve body top, the valve gap top is provided with protective cover, the body cavity Lower Half is spherical, Lower Half is the garden cylindricality, is placed with ball float in it, and the ball float center is coated with fly rod, the fly rod upper end is taper, its upper and lower part is movably arranged on respectively in guide plate and the fairlead, and guide plate is fixed on the valve gap below, and fairlead is fixed on the valve body below;
The center, top of valve gap is equipped with guide pin bushing, slides plug by movable installation of setscrew nut in the guide pin bushing, and sliding plug center is provided with steam vent, and the steam vent lower end is a taper hole, and sealing ring is installed, and the garden is a cone outside the sliding plug lower end, and sealing ring is installed on the conical surface;
The valve gap upper end is provided with pore in garden week.
The utility model compared with prior art, its advantage is reasonable in design, dependable performance, easy for installation, maintenance capacity is little, nothing is leaked, and applicable to any heating boiler, fundamentally avoids heating water boiler to produce vent plug, impact, vibrations, hot-spot or negative pressure damage parts occur reaching owing to the caused leakage of this valve, corrosion phenomenon.
The explanation of accompanying drawing drawing:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model comprises valve body (9), valve gap (12), ball float (10), valve gap (12) is installed in valve body (9) top, valve gap (12) top is provided with protective cover (16), valve body (9) inner chamber Lower Half is spherical, the first half is the garden cylindricality, be placed with ball float (10) in it, ball float (10) center is coated with fly rod (8), fly rod (8) upper end (11) is taper, its upper and lower part is movably arranged on respectively in guide plate (6) and the fairlead (7), guide plate (6) is fixed on valve gap (12) below, and fairlead (7) is fixed on valve body (9) below;
The center, top of valve gap (12) is equipped with guide pin bushing (1), slide plug (13) by movable installation of setscrew nut (18) in the guide pin bushing (1), sliding plug (13) center is provided with steam vent (2), steam vent (2) lower end is taper hole (4), and sealing ring (3) is installed, the garden is cone (5) outside sliding plug (13) lower end, and sealing ring (14) is installed on the conical surface;
Valve gap (12) upper end is provided with pore (17) garden week.
The taper of fly rod (8) upper end (11) equates with steam vent (2) lower end taper hole (4) tapering of sliding plug (13).
Be processed with the internal taper hole (15) that matches with sliding plug (13) cone in the valve gap (12).Be in the boiler when anhydrous before the boiler operatiopn, ball float (10) is positioned at the lower position, steam vent (2) on pore (17) on valve gap this moment (12) and the sliding plug (13) all is in opening, and when boiler feed water, the gas in the boiler can be discharged from pore (17) and steam vent (2).Continuous rising along with water level, water enters in the valve body (9), ball float (10) rises under the buoyancy of water effect, fly rod (8) rises and closed grate hole (2), then, ball float (10) and sliding plug (13) rise in the lump, are adjacent to internal taper hole (15) up to sealing ring (14), at this moment, pore (17) also seals.Boiler water supply stops.
When pot normally moves, along with water temperature rises, steam is more and more, and pressure is increasing, and water level also constantly reduces, at this moment, ball float (10) and fly rod (8) descend, and open steam vent (2), and gas will be discharged, water level rises ball float (10) and fly rod (8) closed grate hole (2) that rises once more again in this moment valve.Finish emergent gas gathering in the boiler operatiopn and so forth, discharge, seal, the process of overflowing again, reassociating, discharging again.When the serious dehydration of boiler, water level descends, and ball float (10) can drop to minimum point, and pore (17) is all opened with steam vent (2), enters air with pore and pressure reduction inside and outside the balance boiler, and boiler is played a protective role.
