Abstract
The utility model particularly relates to a sleeve cage type throttling valve, which includes a valve body, a seal ring, a valve seat, a clamping ring, a sleeve cage, a clamp nut, a valve rod, a hand wheel and a valve rod nut, wherein the valve seat is mounted inside a valve body hole; the clamping ring is used for clamping the valve seat; the valve seat is sleeved with the sleeve cage; the valve rod and the sleeve cage are connected through the clamp nut; small holes are uniformly distributed on the excircle of the valve seat; and a valve rod equalizing hole in the valve rod and a sleeve cage equalizing hole in the sleeve cage are communicated. The sleeve cage type throttling valve has the advantages of erosion resistance, small operation moment, low noise and long service life.
Description
Technical field
The utility model relates to the throttle valve that a kind of rate-of flow control gear, especially wellhead assembly, throttle kill manifold are used.
Background technique
At present, the throttle valve of known wellhead assembly, throttle kill manifold has needle-type throttle valve, hole plate type throttle valve usually.Needle-type throttle valve has the shortcomings such as erosive wear resistance is poor, noise is large; Orifice-plate type throttle operation moment greatly, easily by erosion.
Summary of the invention
The utility model is for the deficiency that existing above problem exists, and provides that a kind of cage type throttling valve possesses higher erosive wear resistance, operational torque is little, noise is little, long service life.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model comprises valve body, seal ring, valve seat, trim ring, cage cover, gland nut, valve rod, handwheel, Stem Mut.Described valve seat is installed in the valve body hole; Described trim ring is used for compressing valve seat; Described cage cover is enclosed within on the valve seat; Valve rod links to each other by gland nut with the cage cover.Even distribution aperture on the described valve seat cylindrical.Described valve rod upper valve rod equalizing orifice puts cage cover equalizing orifice with cage and communicates.
The beneficial effects of the utility model: valve seat, cage cover adopt erosion resistant material; Even distribution aperture impacts the medium ecto-entad mutually on the valve seat cylindrical, reduces the erosion to the valve seat body.Thereby the erosive wear resistance, the operational torque that have improved valve are little, noise is little, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is sectional view of the present utility model.
1. valve bodies among the figure, 2. seal ring, 3. valve seat, 4. trim ring, 5. cage cover, 51. cages cover equalizing orifice, 6. gland nuts, 7. valve rod, 71. valve rod equalizing orifices, 8. handwheel, 9. Stem Mut.
Embodiment
Such as Fig. 1, the utility model valve body (1) and trim ring (4) are with being threaded, trim ring (4) compresses valve seat (3), seal ring (2) is equipped with in valve seat (3) lower end surface, cage cover (5) is enclosed within on the valve seat (3), cage cover (5) links to each other by gland nut (6) with valve rod (7), and valve rod (7) links to each other by Stem Mut (9) with handwheel (8).
Valve rod (7) upper valve rod equalizing orifice (71) communicates with the upper cage cover equalizing orifice of cage cover (5) (51).Play the balance pressure effect, thereby reduce operational torque.
In the time of need reducing flow, right-hand rotation handwheel (8), it is descending that Stem Mut (9) rotarily drives valve rod (7) cage cover (5), and flow reduces gradually.Until contacting fully with trim ring (4), cage cover (5) closes.
When needing augmented flow, left-hand rotation handwheel (8), it is up that Stem Mut (9) rotarily drives valve rod (7) cage cover (5), and flow increases gradually.Until being up to the outer circular hole of valve seat (3) fully, cage cover (5) all exposes.The valve body flow is maximum.
Claims (1)
1. a cage type throttling valve comprises valve body (1), seal ring (2), valve seat (3), trim ring (4), cage cover (5), gland nut (6), valve rod (7), handwheel (8), Stem Mut (9), it is characterized in that: described valve seat (3) is installed in valve body (1) hole; Described trim ring (4) is used for compressing valve seat; Described cage cover (5) is enclosed within on the valve seat (3); Valve rod (7) links to each other by gland nut (6) with cage cover (5); Even distribution aperture on described valve seat (3) cylindrical; Described valve rod (7) upper valve rod equalizing orifice (71) communicates with the upper cage cover equalizing orifice of cage cover (5) (51).
