Abstract
The utility model relates to a maintenance of petrochemical fluid machinery instrument, especially a plunger pump pulls out valve ware. The utility model discloses constitute by pull rod, jump bit. Installing to strike on the pull rod and keeping off the ring sum limit baffle ring, the jump bit suit is on strikeing the pull rod that keeps off between the ring sum limit baffle ring. The utility model discloses a be connected the pull rod and the valve rod of pump valve, utilize the impact force drive pull rod safety of jump bit swiftly to dismantle the pump valve.
Description
Technical field
The utility model relates to petrochemical industry fluid machinery service kit, and especially a kind of plunger displacement pump pulls out valve device.
Background technology
Need in oil extraction process to use high-pressure plunger pump in a large number, the operating pressure of high-pressure plunger pump is high, and the service life of its pump valve is limited, needs frequent dismounting maintain and replace, and because high-pressure plunger pump working media corrosivity is strong, pump valve is easy to corrosion, not quick detachable.201020633005.5 disclose a kind of pump valve disassembling device of high-pressure plunger pump, this device comprises hoisting nut, gasket ring, lift-bolt, valve hanger, pump valve connecting screw rod, support frame, gasket ring is fixed on the end face of support frame, valve hanger is placed on support frame inside, lift-bolt is from bottom to top through valve hanger, support frame, gasket ring, the external screw thread of lift-bolt and the internal thread of hoisting nut screw, valve hanger is suspended on the shoulder of lift-bolt bottom, hoisting nut is located on gasket ring, pump valve connecting screw rod upper suspension is on valve hanger, pump valve connecting screw rod there is external screw thread, rotate and upgrade nut, under threaded function, make lift-bolt generation lifting force upwards, pump valve is extracted from pump head.Under normal circumstances, between pump valve and pump head, frictional resistance is less, uses this device to be taken out from pump head by pump valve easily, but when pump valve gets rusty, combine between pump valve and pump head closely, frictional force is large, and in this device, the torsion of lift-bolt is not enough to pump valve to take out from pump head.
Utility model content
The purpose of this utility model solves above-mentioned high-pressure plunger pump to pull out valve device in use due to the torsion deficiency that lift-bolt is formed, and pump valve is difficult to the defect of extracting, and provides a kind of plunger displacement pump to pull out valve device.
For achieving the above object, the technical scheme that the utility model is taked is:
The utility model is made up of pull bar, jump bit.Pull bar is provided with and impacts baffle ring and limit baffle ring, jump bit is sleeved on the pull bar between impact baffle ring and limit baffle ring.
The utility model is connected with the valve rod of pump valve by pull bar, utilizes the impulsive force of jump bit to drive drag link safety to dismantle pump valve quickly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By reference to the accompanying drawings, the utility model embodiment is provided as follows:
As shown in Figure 1, the utility model forms 2 by pull bar 1 and jump bit and forms, and is provided with and impacts baffle ring 301, pull bar 1 is set with jump bit 2 at the tail end of pull bar 1.
The middle part of described pull bar 1 is provided with limit baffle ring 302.
The front end of described pull bar 1 is branch sleeve, can be threaded with pump valve valve rod 5.
The nose threads branch sleeve pipe nipple 4 of preferred pull bar 1, if sleeve pipe nipple 4 damages, can change in time.
When dismantling pump valve, the branch sleeve of pull bar 1 front end of the present utility model or sleeve pipe nipple 4 are threaded with pump valve valve rod 5.Operating personnel promote the impact baffle ring 301 that jump bit 2 clashes into pull bar 1 tail end repeatedly, pump valve can be extracted.
