Description
Technical field
The utility model is related to fluid conveying control field, particularly a kind of profile control pump valve.
Background technology
Profile control pump is one of indispensable equipment in the profile control of oil field.It is for conveying containing particle blending agent mostly
High viscosity liquid.And the fluid end of profile control pump needs to install profile control pump valve.
Profile control pump valve of the prior art, generally use ball valve, inventor in the process of implementing the utility model, have found
At least there are following defects for common ball valve：Pump valve conveys the high viscosity liquid containing particle blending agent in profile control operation
When, overcurrent sealing surface is easily mingled with has medium with remaining, cannot realize effective sealing, therefore increases the repair of pump valve so that
Pump efficiency declines；The overcurrent sealing surface that valve ball and valve seat are formed is also easy to produce defect and damage, and entire valve ball and valve seat are all reported after damage
It gives up, it is impossible to reuse, therefore the service life of pump valve is short, also considerably increases material and maintenance cost.
Utility model content
The purpose of this utility model is to provide a kind of profile control pump valve, rational in infrastructure, dependable performances, in conveying containing particle
During the high viscosity liquid of blending agent, the circulation of liquid is good, and transfer efficiency is high, and service life is long, easy to maintenance.
What the purpose of this utility model was realized in：A kind of profile control pump valve, including profile control pump, in the fluid end of profile control pump
Profile control pump valve is installed, the structure of profile control pump valve is to be evenly distributed with to be passed through by bonnet its underpart port of liquid outlet in circumferential wall on mouthful
Screw thread is connected with valve seat, coordinates on the centre bore of valve seat and is installed with the valve pocket suitable for reading with mating spherical surfaces seat, positioned at valve pocket
Steel ball guide holder is set on the valve seat on top, and valve ball is matched with the matching seat of valve pocket and the guide holder of valve seat, in bonnet
Lead is set on the back side at top, gland is assembled by spring on lead, gland is matched with valve ball.
Profile control pump valve provided by the utility model, liquid are flowed out by the inlet of valve pocket from overcurrent sealing surface, and outflow is
Into liquid outlet, liquid outlet is around flow-passing surface sealing surface and above logical other than valve ball ontology and a small amount of barrier of position limiting structure
Thoroughly, the relative position of design valve ball and flow-passing surface sealing surface, valve ball central point are apparently higher than overcurrent sealing surface, greatly improve tune
Cut open the liquid communication of pump valve.
Preferably a kind of ceramic material of valve ball, valve ball do not have to replace.Design valve ball is contacted with valve pocket, valve pocket inserted valve seat, valve
Set overcurrent sealing surface, which is broken, only needs to change a new valve pocket, and valve seat does not have to replace.Since the inserted mounting structure of valve pocket is simple,
Squash type takes out repair facility, and manufacture cost is also low so that the service life of pump valve had than in the past to be greatly improved.
The utility model is rational in infrastructure, dependable performance, in the high viscosity liquid for conveying the blending agent containing particle, ensure that
The circulation of liquid, it is easy to maintenance, transfer efficiency is improved, extends service life.
