Abstract
The utility model relates to an automatic air exhaust valve which especially solves the problem that redundant air generated in a fluid pipeline or a device is automatically exhausted. The utility model is mainly composed of an upper flange (1), an air exhaust larynx (2), a core-shaped valve plug (3), a casing (4), a shim (5), a spring (6), a plug guide lug (7), a floating body (8), a bolt nut (9), a flange (10) of a casing, a floating guide plate (11), a lower flange (12), adjusting nuts (13), a lifting lug (14), a lever (15), a flange cover (16), a bolt nut (17) and a pin shaft (18). The utility model has the advantages of less investment, automatic operation completion, labor saving, safety, reliability, simple and reasonable structure and convenient fabrication and installation.
Description
The utility model relates to a kind of valve, in particular for solving the problem of the unnecessary gas that produces in the pipeline of discharging full of liquid automatically or the equipment.
Existing industrial liquid pipeline or equipment (as heat exchanger liquid phase shell side etc.) in, if gathered a large amount of unnecessary gases, lean on artificial exhaust.Artificial exhaust mainly contains several shortcomings: 1. operation inconvenience often needs supporting facility.Because of exhaust outlet point often is in the highest point of all pipelines or equipment, ladder or the facility such as platform up and down for the people must be set.2. poor reliability, exhaust difficult grasp the on opportunity.If gas is not in time discharged, then may influence production, even can cause danger.3. artificial exhaust labor intensity is big, needs artificial often the observation and Open valve.4. frequent ladder, platform up and down of workman easily caused danger.
The purpose of this utility model provides a kind of simple and effective automatic exhaust valve for fluid pipeline or equipment exactly, and it need not artificial exhaust, can reduce equipment investment, improves operational reliability, avoids untimely or the improper and production accident that cause of artificial exhaust; It can also reduce working strength of workers; Avoid the frequent contingent danger of ladder up and down of workman.
The utility model is achieved in that a buoyancy aid (can be floating drum or ball float etc.) is set in the housing of valve, valve plug and buoyancy aid are by leading ear plug or lever is connected, lifting along with liquid level in the housing, buoyancy aid drives valve plug and slides up and down in the exhaust larynx in housing, to open and close valve, in time discharge gas.The leading kickboard and can guarantee that buoyancy aid and valve plug can not tilt of inner walls is so that the closed surface driving fit of valve plug and exhaust larynx is good.The flange at valve two ends is used for connecting fluid pipeline and exhaust duct respectively.The utility model can reduce investment, and complete operation is saved the labour automatically, and is safe and reliable, simple and reasonable, is convenient to make and install.
Now provide embodiment of the present utility model in conjunction with the accompanying drawings
Fig. 1 is a low-pressure type structure sectional view of the present utility model;
Fig. 2 is a medium-pressure type structure sectional view of the present utility model:
Among the figure: 1 is upper flange, and 2 are the exhaust larynx, and 3 are flower core valve plug, 4 is housing, and 5 is pad, and 6 is spring, 7 for leading ear plug, and 8 is buoyancy aid, and 9 is bolt and nut, 10 is shell flange, and 11 for leading kickboard, and 12 is lower flange, 13 for adjusting nut, and 14 is hanger, and 15 is lever, 16 is blind flange, and 17 is bolt and nut, and 18 is bearing pin.As shown in Figure 1 and Figure 2, buoyancy aid (8) is in housing (4), flower core valve plug (3) flexibly connects by leading ear plug (7) or lever (15) with buoyancy aid (8), spring (6) is enclosed within the bar portion of colored core valve plug (3), exhaust larynx (2) is fixed in the housing (4), the colored core segment of flower core valve plug (3) is led kickboard (11) and is fixed in housing (4) inwall in exhaust larynx (2), buoyancy aid (8) and lead between the kickboard (11) and maintain the slit.Lever (15) one ends have adjustment nut (13) among Fig. 2, and the other end is hinged with bearing pin (18) and blind flange (16).
The utility model working principle is as follows: when no too much gas gathers in the housing (4), liquid level is higher, buoyancy aid (8) floats on liquid level and heads on colored core valve plug (3) and upwards close exhaust larynx (2), gaseous pressure also makes the closed surface of colored core valve plug (3) and exhaust larynx (2) be close to simultaneously, at this moment valve closing.If when having produced gas in pipeline or the equipment, gas can rise and enter in the automatic vent valve housing (4) that is installed in the top, at this moment the interior liquid level of housing (4) descends, buoyancy aid (8) is also along with decline, overcome gaseous pressure and affect colored core valve plug (3) to move downward up to its gravity, open valve, discharge gas.Along with the discharge of gas, the liquid level in the housing (4) rises, and buoyancy aid (8) promotes flower core valve plug (3) and rises, up to throttle down also along with rising.So just can realize the automatic opening-closing valve, self-bleeding purpose.Impact force when spring (6) can be alleviated valve opening and closing between flower core valve plug (3) and the exhaust larynx (2), and when closing, can make the closed surface applying of colored core valve plug (3) and exhaust larynx (2) tight and reliable and stable, can not leak.Colored core part of flower core valve plug (3) can be slided in exhaust larynx (2) guiding colored core method plug (3), gas can between its lobe by discharging.The colored core segment of flower core valve plug (3) can be made three lobes or pintongs etc., can wear seal washer on the closed surface of flower core valve plug (3).The closed surface of flower core valve plug (3) and exhaust larynx (2) can be made the plane or the conical surface, and buoyancy aid (8) can be floating drum or ball float etc.
Structure shown in Figure 2 is the medium-pressure type automatic control pressure vent, is more suitable in pipeline or the bigger occasion of equipment internal pressure.To increase the active force of buoyancy aid (8) to flower core valve plug (3), wherein the adjustment nut (13) on the lever (15) can be adjusted the size of this active force by changing its quantity or position, so that open and close valve more reliably with lever (15).
