Description

A kind of pitch drain valve
Technical field
The utility model is related to a kind of drain valves, and in particular to a kind of pitch drain valve.
Background technology
At present, the pitch in asphalt tank is discharged by the way of ball valve mostly, under normal circumstances, gone out on asphalt tank The setting of mouth makes the pitch in asphalt tank be flowed out there are two types of mode, and one kind is horizontal outflow, and one kind is to flow out vertically;Pitch is general All it is to be discharged in the state of heating, is discharged according to the mode of level outflow, when discharge terminates, pitch will cool down solidifying Gu so as to be accumulated in ball valve, since the self structure of ball valve causes valve inner not clear up in time, stockpiled after a period of time Pitch will block valve body so that ball valve can not normal use;
In addition, when using vertical outflow mode, although the problem of stockpiling is improved, discharge is relatively difficult to Control, meanwhile, when ball valve leaks, pitch will flow out automatically under its own weight, cause unnecessary waste.
Utility model content
In order to solve the problems in background technology, the utility model provide that a kind of flow is controllable and valve body inner flow passage not The pitch drain valve that can be blocked.
The utility model solve technical problem specific technical solution be:
The utility model provides a kind of pitch drain valve, including bend pipe and rotation current-limiting mechanism;The bend pipe includes level Section and bending section;Described horizontal segment one end and the outlet of asphalt tank, the other end are connected with bending section;The outlet of bending section End is hinged with rotation current-limiting mechanism.
Further, the rotation current-limiting mechanism includes ear mount, axis pin and arc current limiting plate;The ear mount is mounted on institute Bending section is stated close to the top of the port of export, arc current limiting plate is hinged by axis pin and ear mount, and under natural conditions, arc current limiting plate will The port of export of the bending section is closed.
In order to make port of export contact with arc current limiting plate of bending section better, the bending section exit end face setting There is the arc crimp to match with arc current limliting plate shape;
In order to enable arc current limiting plate is fitted closely with arc crimp, so as to which pitch be made to be not in leakage, which limits Stream mechanism, which further includes, holds out against component;The arc current limiting plate includes arc inner panel and arc outside plate;The arc outside plate passes through pin Axis is hinged with ear mount;The component that holds out against includes housing, step fore-set, spring and puller bolt;One end of the housing with Arc outside plate welds, and the other end of housing is provided with internal thread, and the puller bolt is installed on the coat by the internal thread; The installation direction of housing is parallel with bending section;The step fore-set is located at jacket internal, the end face of the major diameter section of step fore-set with Arc inner plate welding is set with spring in path section;One end of spring is pressed on major diameter section end face, and the other end, which is pressed over, to be held out against On bolt.
Further, it is additionally provided with lifting handle on the arc outside plate.
The problem of crossing conference damage bend pipe in order to avoid rotary position-limit mechanism rotation angle, the rear of the ear mount is provided with Limiting stand.
Further, horizontal segment is connected by the outlet of screw thread and asphalt tank.
The beneficial effects of the utility model are:
1st, the utility model uses bend pipe and rotates the design of current-limiting mechanism, it is ensured that pitch can be clear in time in pipe Reason avoids the problem of pitch blocks valve body.
2nd, the utility model avoids rotation using component is held out against so that limiting arc panel with being fitted closely with arc crimp The problem of pitch leaks when current-limiting mechanism is closed.
3rd, the utility model is additionally provided with lifting handle on arc outside plate, is conveniently operated personnel's operation, avoids due to drip Green temperature excessively high the problem of scalding human hand.
4th, the utility model uses limiting stand, avoids rotary position-limit mechanism rotation angle and crosses asking for conference damage bend pipe Topic.
5th, the utility model is connected the outlet of bend pipe and asphalt tank by screw thread, and the drain valve is dismantled convenient for the later stage.

Specific embodiment
Below in conjunction with the accompanying drawings, the structure of the utility model and operation principle are introduced:
Structure
As shown in Figure 1, pitch drain valve, including bend pipe 1 and rotation current-limiting mechanism 2;Bend pipe includes horizontal segment 11 and curved Tune 12;11 one end of horizontal segment is connected with the outlet 6 of asphalt tank, and the other end is connected with bending section 12;The port of export of bending section 12 It is hinged with rotation current-limiting mechanism 2.
Rotation current-limiting mechanism 2 includes ear mount 21, axis pin 22, arc current limiting plate 23, holds out against component 24 and lifting handle 25; Ear mount 21 is mounted on the bending section 12 close to the top of the port of export, and arc current limiting plate 23 is included outside arc inner panel 231 and arc Plate 232;Arc outside plate 232 is hinged by axis pin 22 and ear mount 21;12 port of export of bending section is provided with and 23 shape of arc current limiting plate The arc crimp 3 that shape matches;
It holds out against component 24 and includes housing 241, step fore-set 242, spring 243 and puller bolt 244;The one of housing 241 End is welded with arc outside plate 232, and the other end of housing 241 is provided with internal thread, and puller bolt 244 is installed by the internal thread On housing 241;The installation direction of housing 241 is parallel with bending section 12;Step fore-set 242 is located inside housing 241, step-shaped top The end face of the major diameter section of column 242 is welded with arc inner panel 231, and spring 243 is set in path section;It is pressed against one end of spring 243 On major diameter end face, the other end is pressed against on puller bolt 244, and the rear of ear mount 21 is provided with limiting stand 4.
Detachable maintaining is carried out in order to facilitate later discharge valve, bend pipe is connected, and pass through by the outlet 6 of screw thread and asphalt tank The adjustment locking of nut 5.
Operation principle
When needing to discharge the pitch in asphalt tank, lifting handle is lifted up, is rotated in current-limiting mechanism Arc current limiting plate will be as illustrated counter clockwise direction rotation, rotate to certain angle and can be limited platform and block, so as to make The port of export for obtaining bend loss is opened, and the pitch in asphalt tank will flow outwardly.When discharge finishes, by lifting handle to decentralization It puts, what the arc current limiting plate in rotation current-limiting mechanism will be as illustrated is rotated clockwise, so that bend loss goes out Mouth end is closed.In order to ensure the leakproofness after closing, need to operate to holding out against component, specifically:Puller bolt is outside It is screwed in set, spring can force the arc inner panel in the tight arc current limiting plate in step-shaped top capital after being under pressure, so as to make in arc The arc crimp of plate and bend loss fits closely.
