Abstract
The utility model provides a lever ball float type automatic draining device suitable for large displacement. The utility model is characterized in that a liquid inlet hole and a liquid outlet hole are respectively formed on the lower section of a full-welding casing, and the liquid inlet hole and the liquid outlet hole are respectively buckled with a press cover; the press cover of one side in the casing is hinged with a rocker whose front end is connected with a big ball float, and the rear section of the rocker is hinged with an opening and closing rod whose lower end is connected with a ball float cover in which an opening and closing ball float is arranged. When condensed water flows into an inner cavity of the casing through the liquid inlet hole and achieves a certain liquid degree, a lever mechanism is driven to rise by the big ball float in order to lift the opening and closing ball float to open a spray hole; contrarily, the liquid level drops, and the lever mechanism subsides with the big float, so that the spray hole is closed.
Description
The utility model relates to a kind of pumping equipment, particularly a kind of lever float ball type automatic drain device.
At present, domestic employed big discharge capacity drain valve, it all is external imported product, its structural feature is to adopt foundry goods to process, and not only volume, weight are big, and because casting defects such as sand holes, crackle, pores, make its reject rate height, and cost rises, and especially under high pressure, worst hot case, is easy to generate leakage.In addition, the keying element of this type of drain valve mostly is taper valve core and the contacted opening structure of valve seat, and it seals desired directivity height, does not satisfy positioning requirements sometimes and then is easy to generate leakage.And this type of opens and closes element and often frequently causes wearing and tearing, is out of shape and causes seal failure because of impacting.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of lever float ball type automatic drain device that adopts ball float as the integral solder structure that opens and closes element is provided.
The purpose of this utility model is to be realized by following technological scheme, at all-welded liquid exhauster housing hypomere one inlet opening and outage are arranged respectively, enter the outage place and respectively linked gland, gland inboard in outage one side is hinged with fork, the fork front end is connected with a hollow float, the fork back segment is hinged with start and stop lever again, the ball float cover of ball float in being fixed with, the start and stop lever lower end is housed, open and close the ball float bottom one liquid-discharging tube is arranged, when condensed water is entered the housing inner cavity and is reached certain liquid level by inlet opening, big ball float floats thereupon and drives leverage and will open and close ball float and lift, condensed fluid is discharged through spray orifice, after liquid level descended, big ball float sank thereupon, opened and closed ball float and was repositioned to again and the identical sealing station of spray orifice.
Therefore remarkable result of the present utility model is:
Because ball float is free to rotate in the ball float cover, therefore, it can carry out omnibearing sealing, and has higher life-span and good sealing effect.
Because the weldment that housing adopts, thereby cost is low, be difficult for leakage.
Volume is little, and is in light weight.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is the A-A cross section view of Fig. 1.
Below in conjunction with accompanying drawing 1-2 concrete structure of the present utility model is described in detail.
The utility model improves the back and realizes on existing drain valve basis, it has housing 1, gland 2, on gland 2, be hinged with fork 3, fork 3 front ends are connected with a big ball float 4, housing 1 hypomere correspondence has inlet opening 5 and liquid outlet opening 6, it is characterized in that: fork 3 back segments are hinged with the start and stop lever 7 of test, start and stop lever 7 lower ends are connected with ball float cover 8, the keying ball float 9 of spherome surface evagination in 8 times apertures of ball float cover put in activity in the ball float cover 8, the spray orifice 10a that opens and closes the spray orifice seat 10 of ball float 9 and its below matches and seals or disengaging, and gland 2 is two respective side of twisting the housing 1 that is connected in welding.
Structure characteristic of the present utility model also is:
Keying ball float 9 is one and can overlaps the hollow ball that freely rotates in 8 at ball float.
Working principle of the present utility model is:
When the condensed water in condensed liquid in the gas engineering equipment or the steam engineering gas utilization unit in inlet opening 5 enters housing 1 and when reaching certain liquid level, big ball float 4 floats thereupon and makes on the fork 3 to be put, when putting on the fork 3, then drive on connected start and stop lever 7 and the ball float 9 and move, 10a opens with spray orifice, condensed fluid is discharged through liquid outlet opening 6, big ball float and fork are sunk under the dead weight effect because condensed fluid is discharged back liquid level falling.Therefore drive keying ball float 9 again spray orifice 10a is blocked, because start and stop lever 7 and fork rear portion are hinged, ball float can be with the swing of ball float cover, the pumping action when adding discharge opeing, and ball float 9 can seal with the Sealing 10b of spray orifice 10a periphery is identical exactly.Open and close ball float when preventing inoperative and press down, bearing support 11 is housed at the housing inner chamber of ball float bottom greatly with the excessive of spray orifice.
Claims (3)
1, lever float ball type automatic drain device, it has housing 1, gland 2, on gland 2, be hinged with fork 3, fork 3 front ends are connected with a big ball float 4, housing 1 hypomere correspondence has inlet opening 5 and liquid outlet opening 6, it is characterized in that: fork 3 back segments are hinged with the start and stop lever 7 of test, start and stop lever 7 lower ends are connected with ball float cover 8, the keying ball float 9 of spherome surface evagination in 8 times apertures of ball float cover put in activity in the ball float cover 8, the spray orifice 10a that opens and closes the spray orifice seat 10 of ball float 9 and its below matches and seals or disengaging, and gland 2 is two respective side of twisting the housing 1 that is connected in welding.
2, according to the described lever float ball type automatic drain of claim 1 device, it is characterized in that: spray orifice seat 10 is connected on the gland 2 and probes in the housing 1 of welding, have L type spray orifice 10a on the spray orifice seat 10, ring-like Sealing 10b is equipped with along periphery in the hole on vertical section of spray orifice 10a.
3, according to claim 1 or 2 described lever float ball type automatic drain devices, it is characterized in that: keying ball float 9 is one and can overlaps the hollow ball that freely rotates in 8 at ball float.
