Abstract

The utility model provides a disassembling and assembling device for a valve seat of a manual-operated flat valve. A tapered hole is formed in one side of a disassembling and assembling module and is matched with a tapered pull block, a tapered pull block pull rod is arranged in the center of the disassembling and assembling module and the tapered pull block, a disassembling and assembling guide barrel is fixedly connected with the disassembling and assembling module through a fixing bolt, and the diameter of an inner hole of the disassembling and assembling guide barrel equals that of an inner hole of the disassembling and assembling module; the tapered pull block pull rod is connected to the tapered pull block through threads and penetrates through the disassembling and assembling guide barrel, and the other end of the tapered pull block pull rod is connected with a tapered pull block pulling nut; a rotating module is connected with the disassembling and assembling guide barrel through threads, and a force adding rod is connected and fixed to the rotating module through threads. The disassembling and assembling device for the valve seat of the manual-operated flat valve has the advantages that an existing hexagon nut is replaced by the rotating module and the force adding rod, a heavy spanner can be placed by the force adding rod, and therefore labor intensity is reduced.

Description

A kind of attaching/detaching apparatus of manual flat valve valve seat
Technical field
The utility model relates to a kind of mechanical device, especially a kind of valve maintenance unit.
Background technology
In throttle kill manifold manual flat valve maintenance process, can involve dismounting and the assembling of valve seat, in the dismounting of valve seat and assembling process, just need a device play the dismounting effect.
In throttle kill manifold manual flat valve overhaul process, when reaching the overhaul life, manual flat valve need to change the consumable accessory that manual flat valve is relevant, in consumable accessory, just comprise o type circle and wavy spring on valve seat, and removing and installing of valve seat just needs a set of attaching/detaching apparatus.Under this condition according to the concrete size design of the practical structures of valve, valve seat a set ofly have a covering device simple in structure, easy to operate, economic actual effect, thereby the turnover job that reaches convenient and swift, high-quality and efficient, completes at low cost manual flat valve.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art and provides a kind of for manual flat valve valve seat attaching/detaching apparatus, has improved the recycling of manual flat valve, has reduced purchase cost.
The technical solution of the utility model is: a kind of attaching/detaching apparatus for the manual flat valve valve seat, comprise dismounting module, tapering pulling block, set bolt, boosting-rod, rotary module, dismounting guide cylinder, tapering pulling block pull bar, tapering pulling block drawing nut, one side of dismounting module has tapered hole, with the tapering pulling block, coordinate, in dismounting module and tapering pulling block, tapering pulling block pull bar is equipped with in center, the dismounting guide cylinder is fixedly connected with by set bolt with the dismounting module, and the dismounting guide cylinder is identical with dismounting module diameter of bore; Tapering pulling block pull bar is threaded connection on the tapering module, passes the dismounting guide cylinder, connects tapering pulling block drawing nut at the other end; Rotary module and dismounting guide cylinder are threaded connection, and boosting-rod is threaded connection and is fixed on rotary module.
The utility model has the advantages that: by installation, use rotary module and boosting-rod to replace existing six square nuts, just can utilize since like this boosting-rod to replace heavy spanner, reduced simultaneously labour intensity.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is the dismounting module, and 2 is the tapering pulling block, and 3 is set bolt, and 4 is boosting-rod, and 5 is rotary module, and 6 are the dismounting guide cylinder, and 7 is tapering pulling block drawing nut, and 8 is tapering pulling block pull bar.
The specific embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.
A kind of attaching/detaching apparatus for the manual flat valve valve seat, comprise that 1 is the dismounting module, and 2 is the tapering pulling block, and 3 is set bolt, and 4 is boosting-rod, and 5 is rotary module, and 6 are the dismounting guide cylinder, and 7 is tapering pulling block drawing nut, and 8 is tapering pulling block pull bar.One side of dismounting module 1 has tapered hole, with tapering pulling block 2, coordinate, tapering pulling block pull bar 8 is equipped with in dismounting module 1 and the interior center of tapering pulling block 2, dismounting guide cylinder 6 is fixedly connected with by set bolt 3 with dismounting module 1, dismounting guide cylinder 6 is identical with dismounting module 1 diameter of bore, tapering pulling block pull bar 8 one sides are connected with tapering pulling block 2 by screw thread, pass dismounting guide cylinder 6, and the other end is connected with tapering pulling block drawing nut 7; Rotary module 5 is connected by screw thread and dismounting guide cylinder 6, and boosting-rod 4 is fixed on rotary module 5.
In the process of overhaul manual flat valve, first handwheel, valve gap, valve plate are dismantled.Left-handed boosting-rod 4 is to certain position, the dismounting position that attaching/detaching apparatus is packed into and will be dismantled valve seat.Dextrorotation tapering pulling block drawing nut 7 produces an outside pulling force, and tapering pulling block 2 forces 1 expansion of dismounting module under the effect of pulling force, thereby makes grinding one's teeth in sleep of dismounting module 1 bite valve base inner wall.By external force, knock the square toes place of tapering pulling block pull bar 8, produce an inside percussion power, dismounting module 1 is bitten valve seat and is moved to the direction of percussion power under the effect of percussion power, thereby makes valve seat split out valve pocket.Left-handed tapering pulling block drawing nut 7, shrink its dismounting module of biting valve base inner wall 1, takes out valve seat, completes dismantlement work.
Attaching/detaching apparatus is put in to installation position, ready valve seat is contained in to dismounting module 1 place.Dextrorotation tapering pulling block drawing nut 7, make dismounting module 1 bite valve base cavity.Dextrorotation boosting-rod 4 produces an outside pulling force, and the manual flat valve end face of flange of take forces attaching/detaching apparatus to drive valve seat and enters valve pocket under the effect of pulling force as supporting surface.After valve seat put in place, left-handed boosting-rod 4, to certain position, left certain stroke space to attaching/detaching apparatus.Left-handed tapering pulling block drawing nut 7, shrink dismounting module 1, thereby dismounting module 1 and valve base inner wall are broken away from, and extracts attaching/detaching apparatus out, completes assembly working.

Claims (1)

1. attaching/detaching apparatus for the manual flat valve valve seat, comprise dismounting module, tapering pulling block, set bolt, boosting-rod, rotary module, dismounting guide cylinder, tapering pulling block pull bar, tapering pulling block drawing nut, it is characterized in that: a side of dismounting module has tapered hole, with the tapering pulling block, coordinate, in dismounting module and tapering pulling block, tapering pulling block pull bar is equipped with in center, the dismounting guide cylinder is fixedly connected with by set bolt with the dismounting module, and the dismounting guide cylinder is identical with dismounting module diameter of bore; Tapering pulling block pull bar is threaded connection on the tapering module, passes the dismounting guide cylinder, connects tapering pulling block drawing nut at the other end; Rotary module and dismounting guide cylinder are threaded connection, and boosting-rod is threaded connection and is fixed on rotary module.
