Description
Technical field
The utility model relates to oil-gas field development field, particularly a kind of fracturing plunger pump valve seals safety more changing device.
Background technique
Current fracturing has become the conventional measure of domestic and international well production increment, and pressure break pump truck used is its key equipment, all adopts plunger pump, relies on the folding of the pump valve assembly in plunger pump and piston/cylinder to realize squeezed fluid body and forms high pressure.Pump valve assembly (being commonly called as valve) is primarily of pump valve body and seal ring composition, pump valve body disabling damage reason as easily worn part be mostly ring wear, aging, follow the string, need in field operation process often to change the seal ring on installation pump valve body.And be generally interference fit between seal ring and pump valve body, install and change seal ring all more difficult.Current also do not have special and shaping plunger pump valve seals to install and replacing instrument, field operation mostly be artificial bottle opener internal diameter of the seal ring is supportted by force large after get in pump valve body, or use easy instrument to be pounded by force by seal ring in pump valve body, these two kinds of methods very easily damage seal ring, and it is low to be mounted to power, high material consumption, inefficiency.
In recent years, how safe and effective quick mounting and change plunger pump valve seals instrument in have made some progress.Publication CN201214227 discloses a kind of device adopting rotatable handle, support, screw mandrel, upper pressure cylinder, lower pressure cylinder and guide sleeve cooperation to carry out rotating the mode installation pump valve seal cushion rubber compressing into operation; Publication CN application number be 203738344 disclose adopt framework, gland, supporting positive cover, the additional jack of moving slide board coordinate the mode headed into install pump valve body O-ring seal; although but said method achieves righting and the protection of pump valve body O-ring seal in installation process; but complex structure; operate relatively loaded down with trivial details simultaneously, be unfavorable for on-the-spot replacing in time.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, be easy to carry about with one, easy to operate, fracturing plunger pump valve seals safety more changing device seal ring is arranged on pump valve body of once property in the situation not damaging seal ring.
For this reason, the technical solution of the utility model is as follows:
A kind of fracturing plunger pump valve seals safety more changing device, is arranged on pump valve body, comprises and advance cover, starting taper body and mounting base.
Described starting taper body comprises upper and lower, described starting taper body top is cone structure, described starting taper body bottom is cylindrical structural, described starting taper body top and joint, described starting taper body bottom are formed with the slope angle of 2 ~ 8 °, described cone center of leading is formed with through hole, and described starting taper body lower inner diameter and described pump valve body top external diameter adapt.The top of described starting taper body is cone structure, and bottom is then columnar structured, plays axially locating effect for righting seal ring, is advanced in the seal groove of pump valve body under being conducive to making seal ring evenly rise slightly state along starting taper body under the promotion advancing cover.
The cylindrical structural that described propelling cover is one end open, described propelling cover is inner is formed with the groove adapted with starting taper shape, is formed with the packing holder for placing seal ring in the aperture edge of described propelling cover.The described end advancing cover to close is for bearing impact when hammer knocks, and open end is processed with packing holder, for placing seal ring and preventing its surface from knocking damage.When carrying seal ring and push starting taper body and complete with the complete plug-in mounting of described inverted cone on the packing holder of described propelling cover, described seal ring is pushed in the seal groove of pump valve body just, completes the installation of pump valve body sealing ring.
Described mounting base local crowning is formed with annular brace seat.Described annular brace seat external diameter is less than described pump body base maximum outside diameter; described annular brace seat internal diameter is greater than the external diameter in described pump valve body bottom protrusion portion; this mounting base is used for laying when changing seal ring and supporting pump valve body, maintains stablizing and protecting pump body base to suffer damage of all parts.
Preferably, the slope angle that described starting taper body top and joint, described starting taper body bottom are formed is 5 °.
Compared with prior art, this fracturing plunger pump valve seals safety more coordinates between changing device utilization propelling cover and starting taper body, axially locating is carried out to seal ring, can in the situation not damaging seal ring once property seal ring is arranged on pump valve body, this device have structure simple, be easy to carry about with one, easy to operate feature, can manpower be saved, improve frock efficiency, be conducive to the cost saving pressing crack construction operation.
