Abstract
The utility model relates to a pipeline control tool, in particular to a thermal recovery steam valve which is used for controlling pipeline systems of power station, metallurgy industry, chemical industry and oil field. The technical proposal is that the utility model mainly comprises a valve (1), a valve flap (2), an upper valve rod (9), a lower valve rod (3), a metal winding (4), a filling pad (5), filling (6), a bracket (7), a fixture block (8), a valve rod nut (10) and a hand wheel (11); the axes of the upper and the lower valve rods and the sideline of the valve connecting end form an angle which is 30 to 60 degrees; the upper and the lower valve rods are connected by the fixture block; the lower valve rod is fixed on the bracket by the valve flap and the hand wheel is fixed on the top of the upper valve rod. The utility model has the beneficial effect that with the angle formed by the axes of the upper and the lower valve rods and the sideline of the valve connecting end, the current resistance can be greatly reduced in the process of opening and closing; because the upper and the lower valve rods are connected by the fixture block, the sealing effect on the sealing surfaces can be promoted; the sealing surfaces of the valve and the valve flap can be fit for wider environment.
Description
One, technical field:
The utility model relates to a kind of pipeline controlling tool, particularly relates to a kind of steam for thermal recovery valve that is applied to pipeline system controls such as power station, metallurgy, chemical industry, oil field.
Two, background technique:
Steam valve is widely used in the pipeline control in fields such as existing power station, metallurgy, chemical industry, oil field, but the problem of its existence is: fluid resistance is big during keying, and the sealing effect of sealing surfaces is poor, and suitable environment is comparatively single.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and fluid resistance was little when a kind of keying was provided, and the good sealing effect of sealing surfaces, suitable environment be the steam for thermal recovery valve widely.
Its technological scheme is: mainly twine (4), Packing seat (5), filler (6), support (7), fixture block (8), Stem Mut (10) and handwheel (11) by valve body (1), flap (2), upper and lower valve rod (9,3), metal and form, the axis of described upper and lower valve rod becomes 30-60 degree angle with valve body connecting end sideline; Connect by fixture block (8) between the upper and lower valve rod, lower valve rod is fixed on the support (7) by flap (2), the top of upper valve rod is handwheel (11) fixedly, the inner chamber of described flap (2) is provided with Packing seat (5) and filler (6), the side is provided with gland (12), is connected with nut (17) by stud bolt (18).
Fixedly handwheel (11) of nut (13), packing ring (14) and impact block (15) is passed through on the top of described upper valve rod.
The beneficial effects of the utility model are: the angle in the axis of the last lower valve rod of employing and valve body connecting end sideline can reduce the resistance of fluid when opening and closing significantly; Connect the sealing effect that can improve mutual sealing surfaces by fixture block between the last lower valve rod; The sealing surface of valve body and flap can make suitable environment more extensive.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described: its technological scheme is: mainly be made up of valve body 1, flap 2, upper and lower valve rod 9,3, metal winding 4, Packing seat 5, filler 6, support 7, fixture block 8, Stem Mut 10 and handwheel 11, the axis of described upper and lower valve rod becomes 30-60 degree angle with valve body connecting end sideline, the best is 45 degree, can reduce the resistance of fluid when opening and closing significantly; Connect by fixture block 8 between the upper and lower valve rod, lower valve rod is tightly done axial lifting during keying, avoid radial friction with sealing surfaces, thereby improved mutual sealing effect, fixture block is fixing by nuts and bolt 16, and lower valve rod is fixed on the support 7 by 2, and is different according to the kind of serviceability temperature and medium, flap has been selected for use corrosion-resistant, anti-abrasive alloy material makes suitable environment more extensive; The top of upper valve rod is handwheel 11 fixedly.The inner chamber of described flap 2 is provided with Packing seat 5 and filler 6, and the side is provided with gland 12, is connected with nut 17 by stud bolt 18.Fixedly handwheel 11 of nut 13, packing ring 14 and impact block 15 is passed through on the top of described upper valve rod, and the side also is provided with label.
