Abstract
The utility model discloses an electro-hydraulic corbula throttle valve, the throttle valve is provided with a sleeve type valve core. The electro-hydraulic corbula throttle valve is characterized in that the barrel of the throttle valve is provided at least two circles of throttle holes, and the number of the throttle holes for each circle is at least two, the throttle holes are uniformly arranged at the circumference of the circle, the throttle hole diameter for each circle increases sequentially from top to bottom. The electro-hydraulic corbula throttle valve adopts the sleeve type valve core, so that the energy of a fluid is consumed when the fluid flows past a throttling hole to enter the cage through the fluid mechanics principle; compared with a conventional throttle valve core, on the condition of the same drift diameter, the inner runner is small, the fluid flows along the centre line of the corbula after throttling, the blunt loss of the fluid to the throttle valve core is greatly reduced, thereby avoiding flashing and cavitation; secondly the throttle holes of the throttle valve core are distributed from small to large, so that the flow of the throttle valve is modulated close to the linearity and is in accordance with the working condition, therefore the characteristic of high flow capacity and high pressure drop can be met for a gas well.
Description
[technical field]
The utility model is a kind of electric liquid cage cover throttle valve, belongs to oil exploration equipment, is used for wellhead assembly and production tree, and flow and pressure are produced in control.
[background technique]
The same with common valve, electric liquid cage cover throttle valve is a throttle element that local resistance can change.When fluid flows through electric liquid cage cover throttle valve, because of throttling valve core causes the circulation area subcontract, form local resistance, the pressure of fluid and speed are changed, produce power loss when fluid flows through the throttle valve spool.Usually the size of representing drag losses with the pressure differential deltap P before and after the valve, the pressure reduction when representing to produce choked flow with Δ PT, if Δ P＞Δ PT, then the fluid that flows in the throttle valve is the choked flow state, is prone to two kinds of phenomenons of flash distillation and cavitation.The generation of choked flow not only influences the selection and the calculating of bore, and will cause destruction of severe noise, vibration, material etc., directly influences the working life of throttle valve.Therefore need be according to the applying working condition of throttle valve, throttling valve core reasonable in design produces the Flow characteristics electric liquid cage cover throttle valve consistent with applying working condition.
[summary of the invention]
In order to prevent that the fluid that flows in the throttle valve from being that flash distillation and cavitation phenomenon appear in the choked flow state, the utility model is designed a kind of electric liquid cage cover throttle valve, can reach the purpose of control flow rate and pressure, keeps the conformity of Flow characteristics and applying working condition.
Design proposal of the present utility model is: a kind of electric liquid cage cover throttle valve, has a sleeve type spool, it is characterized in that, at least two circle throttle orifices are set on the cylindrical shell of spool, the throttle orifice quantity of every circle is at least two and be evenly arranged on the circumference at this circle place, and the throttle orifice diameter in each circle increases progressively from top to bottom successively.
The sleeve type spool that the utility model adopts utilizes fluid mechanics principle to make fluid consume self-energy when throttle orifice enters the cage cover flowing through, compare with conventional throttle valve spool, under same latus rectum situation, its inner flow passage is little, center line along the cage cover after the fluid throttling flows, fluid reduces greatly to the damage of dashing of throttling valve core, can avoid occurring flash distillation and cavitation phenomenon thus; Secondly, the ascending throttle orifice characteristic distributions of throttling valve core makes the flow modulation of throttle valve approach linearity, and consistent with applying working condition satisfies the characteristics of gas well high flow capacity high pressure drop.

[embodiment]
Be described further below in conjunction with the utility model embodiment and accompanying drawing thereof.
Present embodiment is a kind of electric liquid cage cover throttle valve, has a sleeve type spool 1 as shown in Figure 1, at least two circle throttle orifices 2 are set on the cylindrical shell of spool 1, throttle orifice 2 quantity of every circle are at least two and be evenly arranged on the circumference at this circle place, and throttle orifice 2 diameters in each circle increase progressively from top to bottom successively.
The throttle orifice 2 of present embodiment setting is four circles, and every circle throttle orifice 2 quantity are four, all throttle orifices 2 on spool 1 cylindrical shell distributing position shown in the unfolded drawing of Fig. 2.The equivalent diameter of all throttle orifice 2 additions is 2.8 inches.
