Abstract
The utility model relates to a fast open -blind board is equipped with the barrel flange and can inlays into the blind plate skull in the barrel flange, be equipped with sealed face between barrel flange and the blind plate skull, seal cover spare is equipped with on the sealed face, be equipped with fixed nipple joint under fixed nipple joint on the rocking arm, the rocking arm on the outer wall of barrel flange one side, be fixed with the fixed rocking arm of a blind plate skull on the rocking arm under fixed nipple joint and the rocking arm between the fixed nipple joint, the fixed rocking arm of blind plate skull passes through fixed nipple joint of blind plate skull and blind plate skull fixed connection, be equipped with the manual crow bar of unscrewing on the fixed rocking arm of blind plate skull, still be equipped with safe locking mechanism on the blind plate skull. The utility model is suitable for a pipeline under pressure, pressure vessel have that the design is scientific, rational in infrastructure, the switching is quick, convenient operation, and sealing performance is good, and the preparation is easy, the wide advantage of application scope.
Description
Technical field
The utility model belongs to a kind of fast-opening blind on the circular open such as pressure piping, pressurized container, and this fast-opening blind is the mechanical device belonging to special equipment scope, can realize unlatching and closing function fast.
Background technique
At present, in the corollary equipment such as pressurized container, pressure piping, fast-opening blind is a kind of conventional quick unlatching or shutoff device.Fast-opening blind structure mainly contains following several, i.e. clamp band type, castellated, plug-snap type and lock-ring-type fast-opening blind.The first clamp-type quick opening blind plate drives tightening up of two or more clip by screw rod, blind plate end cap and shell flange are compressed, seal ring is made to produce distortion, thus realize sealing, but clamp-type quick opening blind plate is when opening and closing, needing special instrument makes blind plate end cap and shell flange compress, larger to the moment of torsion of bigbore needs, if for a long time need not, even cause screw thread to glue together, can not open, need in operation to carry out adjusting to ensure centering, so operate loaded down with trivial details, therefore opening and closing speed is relatively slow.The castellated fast-opening blind locking method of the second leans on the inclined-plane of cylindrical shell and blind plate upper teeth to engage each other realization, and its shortcoming is that the angle requirement on each tooth inclined-plane is completely the same, and during locking, each tooth must contact simultaneously, and difficulty of processing is large, wastes time and energy.The third eye-splice type fast-opening blind plate is rotated by interruption single head or multiple thread between blind plate end cap and simplified flange to gnaw conjunction, makes O shape circle be subject to the effect of axial force and be out of shape, thus realize sealing.But blind plate machining is complicated, if do not use for a long time, easily glue together, occur being difficult to the situation of opening, open during work, close that to apply moment of torsion excessive, and be only limitted to use on small-bore equipment.
Model utility content
The purpose of this utility model is to solve the problem, and proposes a kind of fast-opening blind, and this fast-opening blind has design science, rational in infrastructure, opening and closing quick, easy to operate, good seal performance, makes easily, feature applied widely.
The purpose of this utility model is achieved through the following technical solutions: fast-opening blind, be provided with shell flange and the Blind plate head in shell flange can be inlaid into, it is characterized in that: between described shell flange and Blind plate head, be provided with sealing surface, described sealing surface is equipped with Seal Kit, described shell flange side outer wall is provided with on pivoted arm fixes pipe nipple, pipe nipple is fixed under pivoted arm, fix under described pivoted arm being fixed pipe nipple and pivoted arm and be fixed with a Blind plate head between pipe nipple and fix pivoted arm, described Blind plate head is fixed pivoted arm and is fixed pipe nipple by Blind plate head and be fixedly connected with Blind plate head, described Blind plate head is fixed pivoted arm and is provided with crowbar of manually outwarding winding, described Blind plate head is also provided with safety locking mechanism, described safety locking mechanism manually lock-up wheel controls to open and closed state.
Described Seal Kit adopts the compound mode of a U-shaped seal ring, an anti-extrusion eyelet, 1 O type pad, the model of described U-shaped seal ring: FKM.
1, the utility model opening and closing is quick, easy to operate, structurally take into full account the on-the-spot operational condition possessed, installation, maintenance, easy to operate, and when opening and closing, operate without the need for special tool, open and close fast, simple, convenient, labor intensity is low, time saving and energy saving;
2, quality is good, and rational in infrastructure making does not need very large power when opening and closing, and large small-bore difference in operation is little, and this makes component not easily occur the phenomenons such as wearing and tearing gummed, and quality is good, long service life, and sealing is reliable, and pressure is higher, and sealing is better;
3, make easily, applied widely, make easily simple, and applied widely, the utility model is not only applicable to vertical equipment, is also applicable to horizontal equipment, is not only applicable to heavy caliber equipment, is also applicable to small-bore equipment.
Accompanying drawing explanation
Fig. 1 is closed state structural representation of the present utility model;
Fig. 2 is opening state structural representation of the present utility model;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, 2, fast-opening blind, the Blind plate head 2 being provided with shell flange 1 and can being inlaid in shell flange, sealing surface is provided with between described shell flange and Blind plate head, described sealing surface is equipped with Seal Kit, described shell flange side outer wall is provided with on pivoted arm fixes pipe nipple 4, pipe nipple 3 is fixed under pivoted arm, fix under described pivoted arm being fixed pipe nipple and pivoted arm and be fixed with a Blind plate head between pipe nipple and fix pivoted arm 5, described Blind plate head is fixed pivoted arm and is fixed pipe nipple 6 by Blind plate head and be fixedly connected with Blind plate head, described Blind plate head is fixed pivoted arm and is provided with crowbar 7 of manually outwarding winding, described Blind plate head is also provided with safety locking mechanism, described safety locking mechanism manually lock-up wheel 8 controls to open and closed state, described Seal Kit adopts the compound mode of a U-shaped seal ring, an anti-extrusion eyelet, 1 O type pad, the model of described U-shaped seal ring: FKM.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
