Description
Technical field
The utility model relates to throttle valve technology field, particularly a kind of drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy.
Background technique
Along with the development of domestic and international deep-well and ultra-deep well drilling, the throttling performance of drilling well throttle valve and safety and reliability come into one's own day by day.In oil drilling ground high-pressure liquid control apparatus or device, throttle valve is the core component of drilling pressure, flow control, by regulating the aperture of throttle valve, reaches the object controlling well head or bottom pressure or flow.At present, the throttle valve that domestic drilling well uses, for solving broken by vibration problem, adopts a kind of wedge shape throttle valve as standard configuration.There are the following problems for it: above-mentioned throttle-valve structure brings serious side direction erosion (nonsymmetry erosion) problem, has caused a lot of serious accident, has caused huge economic loss.Such as in August, 2013 is in the drillng operation of Xinjiang Shun Nan 5 well, when the throttling of huge discharge High Pressure Difference because of wedge shape throttle valve side blow (nonsymmetry erosion) the throttle valve upstream device that it uses, finally causes rig to be burnt.
Therefore the characteristic that throttle valve has the anti-side blow of energy (nonsymmetry erosion), against shock ruptures how is made to be problem to be solved in the utility model.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy reasonable in design, easy to use, it is simple that it has structure, cost is low, reasonable in design, there is anti-asymmetric erosion and vibration proof fracture energy, the advantages such as stable drilling well throttling requires can be met.
For achieving the above object, the technical solution adopted in the utility model is:
The drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy described in the utility model, it comprises throttle body, and described throttle body comprises a valve body, is provided with valve seat and valve core housing, valve seat is provided with valve core housing in this valve body; One spool is set in described valve core housing, this spool is evenly provided with five small through hole; One valve rod is set in valve core housing; This valve rod is connected by screw thread with spool.
Further, described valve core housing outer surface is coated with cemented carbide surface layer.
After adopting said structure, the utility model beneficial effect is: the drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy described in the utility model, it is simple that it has structure, cost is low, reasonable in design, there is anti-asymmetric erosion and vibration proof fracture energy, the advantages such as stable drilling well throttling requires can be met.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, the drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy described in the utility model, it comprises throttle body, and described throttle body comprises a valve body 4, be provided with valve seat 1 and valve core housing 3 in this valve body 4, valve seat 1 be provided with valve core housing 3; One spool 2 is set in described valve core housing 3, this spool 2 is evenly provided with five small through hole; One valve rod 5 is set in valve core housing 3; This valve rod 5 is connected by screw thread with spool 2.
Preferred as one of the present utility model, described valve core housing 3 outer surface is coated with cemented carbide surface layer.
Working principle of the present utility model:
Throttle valve is in throttling process, and fluid enters valve body 4, the hard alloy surface of direct washout valve core retainer plate 3, and spool 2 stretches out from interior movement of valve core housing 3, avoids inlet fluid and directly impacts spool 2 from regulation of longitudinal angle.Spool 2 is under the traction of valve rod 5, axis along valve seat 1 moves, run through five small through hole of spool 2, connecting valve core retainer plate 3 inner chamber and throttle valve downstream, guarantee that the pressure in these two spaces realizes real-time transient equiliblium, avoid these two space mineralization pressures poor, thus make spool 2 when axis moves held stationary, can not produce pressure reduction vibration.Because the design has the valve core housing of band cemented carbide surface layer and the spool of band five small through hole, thus there is when throttling anti-asymmetric erosion and vibration proof fracture energy.
The drilling well throttle valve with anti-asymmetric erosion and vibration proof fracture energy described in the utility model, it is simple that it has structure, and cost is low, reasonable in design, has anti-asymmetric erosion and vibration proof fracture energy, can meet the advantages such as stable drilling well throttling requires.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
