Specific embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following embodiment, and cooperate attached drawing
Detailed description are as follows:
Referring to Figure 1 to Fig. 4, the protecting apparatus special of a kind of flange and union, including protecting crust, the protecting crust include
Shell 6 and cap 2, the shell 6 and the cap 2 are removably butted into cylindrical body, and the shell 6 and the cap 2 can
It is docked and is fastened by a variety of removablies such as bolt, the appearance for accommodating flange 8 or union 7 is equipped in the cylindrical body
Chamber, the cylindrical body both ends are equipped with the spout part 9 being socketed with pipeline 3, and the shell 6 and the cap 2 can be arranged in spout part 9
Bolt etc. is docked and is fastened, and 2 top of cap is equipped with overflow port 1, and 6 lower part of shell is equipped with fluid guidance port, described to lead
Liquid mouth is connected with liquid storing tube 5.The vertical and horizontal installation connection direction that flange 8 or union 7 in pipeline 3 can be corresponded to, determines cap 2
Upper position and shell 6 lower position, 2 corresponding position of cap be arranged overflow port 1,6 corresponding position of shell setting lead
Liquid mouth keeps protecting crust horizontal positioned or is disposed vertically, and overflow port 1 is all located at protecting crust top, and fluid guidance port is all located at protecting crust
Lower part, overflow port 1 are higher than fluid guidance port.Fluid guidance port is located at protecting crust lowest part as far as possible, convenient for liquid outflow in cavity.It can will prevent
Protective case overflow port 1 and fluid guidance port are diagonally arranged up and down, and the protecting crust of this set is generally applicable, can be not only used for flange 8 or union 7
It is horizontally mounted connection, it can also be used to which no matter the connection of the right angle setting of flange 8 or union 7, this protecting crust are disposed vertically or water
Placing flat can be such that its overflow port 1 is located above fluid guidance port.
The cylindrical body both ends are equipped with the spout part 9 being socketed with pipeline 3, and the spout part 9 can be equipped with annular seal grooves,
Sealing ring is equipped in the annular seal grooves.The elastic seal ring of the preferred non-metallic material of sealing ring, such as rubber seal,
Resin seal circle etc.；The spout part 9 and pipeline 3 of the protecting crust are socketed, and are fastened by bolt, in annular seal grooves
It is interior to be equipped with sealing ring, it can make to seal between the spout part 9 of the protecting crust and pipeline, prevent liquid from flowing out from nozzle；Simultaneously
After the spout part 9 and pipeline 3 of protecting crust fasten, flexible sealing ring is set between spout part 9 and the outer surface of tube wall of pipeline 3,
The frictional force between the protecting crust and pipeline is also increased in this way, avoids the protecting crust relative duct size sliding, and bullet
Property the also absorbable vibration of body, avoid relative impact between the protecting crust and pipeline and therefore caused by the protecting crust
It is damaged.
Two radial ringed boss can be also set in the cylindrical body；Union 7 is located between two annular convex platform and quilt
The relatively described cylindrical body sliding of limitation.It prevents from vibrating because of pipeline 3,7 crash shell of flange 8 or union damages protecting crust.
Cylindrical body can be preferably cylindrical shape for the various shapes such as rectangular, round, the cylindrical body.This structure fabrication letter
It is single, the cutting of molding round tube and welding manufacture can be used.
The shell 6 and the cap 2 are removably butted into cylindrical body, can connect institute using a variety of removablies
Shell 6 and the cap 2 are stated, makes the shell 6 and the cap 2 is easy to disassemble is also convenient for being socketed in outside flange 8 or union 7.
The detachable connection method of one of shell 6 and cap 2 is to be connected by screw bolts the shell 6 and the cap
2: the present invention may also include bolt；The shell 6 and the cap 2, the two are correspondingly provided with the connection of docking in central axes two sides
Ear 4, the engaging lug 4 are equipped with connecting hole, and the bolt penetrates the connecting hole and and nut check.Screw bolt and nut will dock
Engaging lug 4 tighten together, so that the shell 6 and the cap 2 be tightened together.
It is that side uses radial type to connect that there are also a kind of shells 6 with the detachable connection method of cap 2, and the two other side is adopted
With detachable connection:
The shell 6 and the cap 2, the two side can connect for radial type, and the two other side can be detachable company
It connects.
Clamping connection can be used in detachable connection, can also be bolted using above-mentioned.The shell 6 and the shell
The detachable connection of lid 2 is preferably clamped connection.Grab mode can be used in clamping connection, for example, the cap 2 is detachable
Formula connecting side can be equipped with grab, and the shell 6 can be equipped with the clamping portion cooperated with the grab.
To be completely embedded shell 6 and the cap 2, the shell 6 and the cap 2 are equipped with phase interworking in interface
The protrusion and groove of conjunction.Also settable sealing ring in groove, prevents leaked liquid.
For convenience of observation, find that the leakage problem of flange 8 or union 7, the liquid storing tube 5 are transparent oil pipe in time.
The working principle of the invention: when smaller fluid leakage occur in flange or union junction, liquid flows into protecting crust
Liquid storing tube, liquid storing tube can be transparent oil pipe, can be made by transparent plastic material, staff can by observation liquid storing tube whether
Liquid storage, judges whether pipeline junction has liquid leakage, convenient for processing problem in time, checks leakaging cause；When junction occurs
Fluid thorn leakage, liquid will be injected on the protecting crust of protective device, after protecting crust buffering lets out power, liquid flow into liquid storing tube 5 or from
Overflow port 1 is discharged, and liquid thorn leakage is avoided to cause to damage to equipment and personnel.
Embodiment described above is merely to illustrate technical idea and feature of the invention, in the art its object is to make
Technical staff it will be appreciated that the contents of the present invention and implement accordingly, patent model of the invention only cannot be limited with the present embodiment
