The utility model adopts two orifice plates up and down, open one and a half months type through hole at the Ban Yuanchu of every orifice plate, by the size of the limited change aperture of relative energy of rotation of two orifice plates up and down, reach the purpose of transferring flow from the standard-sized sheet to the full cut-off, orifice plate adopts high abrasion resisting material to form, can be effectively through frayed and corrosion, during use, handwheel dextrorotation, flow reduces, and left-handed flow increases.
The cemented carbide orifice plate of diamond lap is ground to the planeness that need are measured by edge of a knife chi, guarantees two orifice plates adhesives mutually up and down.
The utility model is definitely closed, one 17 ° the dead band of having gone back crossover when two orifice plates surpass full close position up and down, be in the fluid that contains abrasive material for a long time and still assurance closure under the situation of wearing and tearing at orifice plate, under pressure reduction or fluctuation situation, can not influence the quality of plate to the plate sealing, in fact, pressurized lower seal performance is better.
A lengthening wear sleeve of stretching out end face of flange is arranged in the endoporus of the present utility model, and this wear sleeve adopts cemented carbide manufacturing, can improve working life, and the wear sleeve of lengthening can play and absorb the energy that washes away and the effect of anti-attrition, is in underbalance drilling well by it.
Open and close of the present utility model are that to adopt the drive unit that surges be that the angle valve controller carries out, can guarantee the to surge open and close of drilling well orifice control valve of this drive unit that surges.
Be configured to removable crossover flange short circuit at outlet end of the present utility model, this crossover flange short circuit can make things convenient for the user to exchange according to different pressures grade, latus rectum and be connected, and do not need to reconfigure new orifice control valve, and can under the prerequisite of not removing whole orifice control valve, change wear sleeve.
In the utility model, there is not a rubber seal, valve gap and valve body, crossover flange short circuit and valve body adopt metal to metal seal, sealing steel rings adopts the stainless steel manufacturing of 300 series, can reuse, lip packing and sealing steel rings are adopted in the sealing of valve rod and valve gap, and its material is the 777PTFE+Eigloy elastic skeleton, and this lip packing maximum can be born the pressure of 20000Psi, can be low temperature resistant-120 ℃, high temperature resistant 288 ℃.Orifice plate bracket and valve body adopt rectangular seal, wear sleeve and crossover flange short circuit to adopt the O RunddichtringO, rectangular seal 14 all adopts the PEK borrow with the sealing of O RunddichtringO 11, this PEK borrow has excellent sealing ability, can be under ultralow temperature and ultra-high temperature condition proper functioning.
It is to realize by the angle valve controller that matches that aperture of the present utility model is regulated, and has an indicator of opening to show the whole process of orifice plate from " standard-sized sheet " to " complete shut-down " position on the angle valve controller.
Angle valve controller of the present utility model can exchange use with the gear device of hand drill wellhole plate throttle valve.
The utility model has the advantages that good seal performance, wear sleeve can be changed, and can know the process of orifice plate standard-sized sheet and complete shut-down.
