Abstract
The utility model provides a device suitable for valve valve rod withdraws from, including consecutive landing leg, the oil tank, the handle, manual hydraulic pump, defeated oil pipe, the jack, the blind plate, a screw rod, through using the device, it is difficult to extract to have solved present valve valve rod, it is hard during the valve rod exit fee, the low scheduling problem of work efficiency, it withdraws from only to need alone can to accomplish the valve rod, withdraw from the in -process at the valve rod, the phenomenon of rocking about can not appearing, valve rod and filler have been protected, and the valve rod withdraws from efficiently, the spoilage is low, the operation is thus simple, it is convenient.
Description
Technical field
The utility model relates to a kind of valve rod extracting apparatus, is particularly applicable to the device that valve rod exits.
Background technology
When assembling valve, valve rod being encased in the operation carrying out a no leakage after in valve rod hole, if valve gas leakage, just needing valve rod to take out from valve rod hole; In addition, in the Long-Time Service of valve, along with under the effect such as the rotation of the switch of valve, the erosion of internal liquid, valve also there will be interior leakage, and in Chemical Manufacture, valve uses more, all can there is a large amount of interior valve leaked every day, valve rod must be extracted by internal leakage valve, thus additional fillers, prevent interior leakage.At present; valve rod for valve exits; the mode adopted is that manually the instrument such as direct spanner or pliers is outwards extracted; if the larger needs of valve two people can extract valve rod in turn; in the process of extracting, often valve rod can be caused to be out of shape, to scrap due to double swerve; waste time and energy, operating efficiency is low.
Summary of the invention
The utility model solves that current valve rod is difficult to extract, valve rod exits wastes time and energy, the inferior problem of inefficiency, by using valve rod extractor, only need a people can complete valve rod to exit, and valve rod exits that efficiency is high, spoilage is low, simple, convenient.
The technical solution adopted in the utility model is: a kind of device being applicable to valve rod and exiting, and comprises the supporting leg, oil tank, handle, hydraulic hand-pump, petroleum pipeline, jack, blind plate, the screw rod that are connected successively; Hydraulic hand-pump is connected with jack by petroleum pipeline; Screw rod one end has external screw thread, and the other end connects with blind plate.
Described a kind of device being applicable to valve rod and exiting, its jack is fluid pressure type hollow jack, facilitates the even power of valve rod to extract.
Described a kind of device being applicable to valve rod and exiting, the screw thread of its screw rod one end is external screw thread, can screw up, be convenient to valve rod and exit with valve rod.
Described a kind of device being applicable to valve rod and exiting, its screw rod and blind plate adopt welding manner to be connected, and connect closely not fragile.
Described a kind of device being applicable to valve rod and exiting, its blind plate diameter is greater than hollow jack interior diameter.
The beneficial effects of the utility model: by using a kind of device being applicable to valve rod and exiting; solve that current valve rod is difficult to extract, valve rod exits and waste time and energy, the inferior problem of inefficiency; by using valve rod extractor; only need a people can complete valve rod to exit; exit in process at valve rod; there will not be the phenomenon of double swerve; protect valve rod and filler; and valve rod exits, and efficiency is high, spoilage is low; simple, convenient, the utility model has the advantages such as structure is simple, simple operation.The utility model is applicable in the technology of industrial valve maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1 is supporting leg, and 2 is handle, and 3 is oil tank, and 4 is hydraulic hand-pump, and 5 is petroleum pipeline, and 6 is blind plate, and 7 is screw rod, and 8 is jack.
Detailed description of the invention
With reference to accompanying drawing 1, a kind of device being applicable to valve rod and exiting, comprise the supporting leg 1, oil tank 3, handle 2, hydraulic hand-pump 4, petroleum pipeline 5, jack 8, blind plate 6, the screw rod 7 that are connected successively; Hydraulic hand-pump is connected with jack by petroleum pipeline; Screw rod one end has external screw thread, and the other end connects with blind plate.
Another embodiment difference is that its jack is fluid pressure type hollow jack, facilitates the even power of valve rod to extract.
Another embodiment difference is that the screw thread of its screw rod one end is external screw thread, can screw up, be convenient to valve rod and exit with valve rod.
Another embodiment difference is that its screw rod and blind plate adopt welding manner to be connected, and connects closely not fragile.
Another embodiment difference is that its blind plate diameter is greater than hollow jack interior diameter.
Utility model works principle: after valve is dismantled, remove link and executing agency, after opening gland, expose valve rod, fluid pressure type hollow jack is enclosed within valve rod, and hollow jack base is placed in valve top, screw rod with blind plate is inserted hollow jack, and screwed one section is screwed up mutually with spiral shell in valve rod top, then open hydraulic hand-pump, press handle, hollow jack is under the effect of hydraulic pressure, by blind plate jack-up, be with ovable valve stem simultaneously, thus valve rod is exited.
Claims (3)
1. be applicable to the device that valve rod exits, it is characterized in that: comprise the supporting leg, oil tank, handle, hydraulic hand-pump, petroleum pipeline, jack, blind plate, the screw rod that are connected successively; Hydraulic hand-pump is connected with jack by petroleum pipeline; Screw rod one end has external screw thread, and the other end connects with blind plate.
2. a kind of device being applicable to valve rod and exiting according to claim 1, is characterized in that: jack is fluid pressure type hollow jack.
