Abstract
The utility model provides a cage cover choke valve, belong to the choke valve that oil mining manufacture used, by the valve body, a valve cove, a valve sea, the valve rod, the valve lever bushing, and a valve cor, the cage cover, the stem guide sleeve, the cylindric lock, locking screw assembles the component, characterized by case excircle has together the chimb that is compressed tightly by the disk seat bottom surface, the circle has 90 recess sealing conical face in the disk seat, be equipped with 90 recess sealing conical face with 90 recess sealing conical face complex valve rods of disk seat and the corresponding end of valve lever bushing, is furnished with the cage cover between stem guide sleeve and the disk seat, case accessible valve gap, the stem guide sleeve, the installation of cage cover and disk seat is compressed tightly, the cage cover is equipped with flow channel hole and asymmetric installation locating hole, and it is fixed with the stem guide sleeve through corresponding locking screw, make cage cover flow channel hole and valve body flow channel hole relative direction. The utility model is suitable for a producing well below the pressure rating 42Mpa is used for controlling the production flow and the pressure of oil gas well.
Description
Technical field
The utility model belongs to the throttle valve of oil exploration equipment, is especially applicable to the producing well of below pressure rating 42Mpa, is used for controlling the production flow of Oil/gas Well and the cage type throttling valve of pressure.
Background technique
Conventional throttle valves in off position time, valve rod and valve base chamber cannot form effective sealing, and this just causes producing under flow needs the strict working condition controlled, and valve there will be comparatively gross leak amount, causes the problems such as upstream device work overload; Due to reasons in structure, throttle orifice intensity under large flow fluid impacts of conventional throttle valves spool is lower, and easily rush damage, structure is not firm.For this situation, my company develops a kind of large discharge low leakage cage cover throttle valve, and adopt pole socket conical surface seal technology, when making valve in off position, leakage class reaches V level; Improve the orientation type of spool simultaneously, throttle orifice is distributed more reasonable, the usage requirement of large discharge can be met completely.
Summary of the invention
The utility model needs the problem solved to be to provide-kind of large discharge low leakage cage cover throttle valve.
The technical solution of the utility model is by valve body, valve gap, valve seat, valve rod, valve lever bushing, spool, cage cover, stem guiding sleeve, straight pin, lock screw assemblies, it is characterized in that spool cylindrical has the chimb compressed by valve seat bottom surface together, valve seat inner circle has 90 ° of groove sealing cones, the valve rod coordinated with valve seat 90 ° of groove sealing cones and the corresponding end of valve lever bushing are provided with 90 ° of groove sealing cones, cage cover is furnished with between stem guiding sleeve and valve seat, spool is by valve gap, stem guiding sleeve, the installation of cage cover and valve seat is compacted, cage is arranged with runner hole and asymmetric mounting-positioning holes, and fixed by corresponding lock screw and stem guiding sleeve, cage is made to overlap runner hole and valve flowing channel hole opposite direction.
The utility model is compared with conventional throttle valves, its difference is: 1. the means of fixation of spool becomes compression type from the embedded of routine, embedded spool, due to the restriction (being threaded) of valve seat, makes spool cylindrical cannot be excessive, and the throttle orifice size that cylindrical is offered then is restricted, and compression type spool is by seat compression, valve seat is structurally overlapped by cage and compresses, and spool cylindrical can design comparatively large, and the conventional structure avoided is to the restriction of throttling spool hole size, and throttle orifice distribution is more reasonable, and spool intensity is higher, can meet large discharge requirement, 2. valve lever bushing is designed with 90 ° of groove sealing cones, during valve closing, this conical surface can compress with the valve seat conical surface, form the sealing of the conical surface two road, this structure can make valve leak grade bring up to V level, and the valve rod cemented carbide lining of conventional throttle valves and valve base chamber are plane compresses, precision is low, uncontrollable leakage rate, 3. spool outside adds cage cover, this cage is enclosed within mounting type and adopts asymmetric mounting-positioning holes, and control cage cover direction, runner hole (relative with valve flowing channel hole) by corresponding lock screw and straight pin, reduce the impact energy that fluid overlaps cage, fluid is smoothly passed at place of valve core axis, protection valve outlet end is not by erosion, improve spool intensity, enhance sealability, simplify maintenance program, can meet on-the-spot to low pressure loss, the usage requirement of large discharge operating mode, be applicable to pressure rating 42Mpa(2500LB) following producing well, be used for controlling the production flow of Oil/gas Well and pressure.

Embodiment
The utility model is by valve body 9, valve gap, valve seat 2, valve rod 4, valve lever bushing 3, spool 1, cage cover 5, stem guiding sleeve 7, straight pin 8, lock screw 6 assemblies, spool cylindrical has the chimb compressed by valve seat bottom surface together, valve seat inner circle has 90 ° of groove sealing cones, the valve rod coordinated with valve seat 90 ° of groove sealing cones and the corresponding end of valve lever bushing are provided with 90 ° of groove sealing cones, 90 ° of groove sealing cone roughness 0.8, cage cover is furnished with between stem guiding sleeve and valve seat, spool is by valve gap, stem guiding sleeve, the installation of cage cover and valve seat is compacted, cage has put runner hole and asymmetric mounting-positioning holes, and fixed by corresponding lock screw and stem guiding sleeve, cage is made to overlap runner hole and valve flowing channel hole opposite direction.Valve rod and the valve seat of cage cover throttle valve adopt 90 ° of groove conical surface seals, can form the sealing of the conical surface two road, solve valve internal leakage problem when valve closing compresses.
