Description
Technical field
The utility model belongs to the improvement of the matching used throttling resistance oil nozzle sleeve of oil-extracting well structure in field produces, the particularly adjustable resistance oil nozzle sleeve of a kind of pin type.
Background technology
Current existing choke valve is divided into fixed and adjustable.
Fixed, with the oil nozzle of different pore size, by being threaded into, in resistance oil nozzle sleeve, regulate fluid flow.During each adjusting of this fixed choke cover, all want plug that dismounting oil injection nozzle puts and original filled oil nozzle, be replaced with the oil nozzle in required aperture, do like this labour intensity large, can not make continuously linear regulation, and in the situation that oil well valve lost efficacy, change oil nozzle and have potential safety hazard.
Adjustable needle type choke valve does not have indication mechanism, or only has simple indication mechanism, and to the adjusting of flow very inaccuracy, and valve inner is by serious erosion corrosion, affects and uses safety.1, traditional product only has two ports, needs to weld in addition at the scene pipeline, to connect sampler or experimental rig etc.Increase work and material cost; 2, the sealing component of traditional product, are fixedly connected with by welding or other modes, to the accuracy of manufacture, require high; Be worn or after impurity interferes, very easily distortion walks, effect is closed in impact.3, traditional product is for being threaded or flange form connects, complex operation.4, traditional product is being used Field adjustment seal assembly inconvenient, or has ejection dangerous at adjustment process shaft; 5, when traditional product need to regulate maximum diameter of hole, integral demounting could be changed to hole circle.Efficiency is low, and labour cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of pin type adjustable resistance oil nozzle sleeve, and it is rational in infrastructure, and performance safety is reliable, can with multiple pipeline or equipment connection, adjust flux quick and precisely, can show the size of flow channels intuitively, and use, installation, easy to maintenance.
The purpose of this utility model is achieved in that the adjustable resistance oil nozzle sleeve of a kind of pin type, the main body with cross four-way mouth, its left side, right port and bottom port are respectively a left side with hoop, right tube connector and lower tube connector, top port is the core base that upper end has the turbination hole of ladder concave station, the conical sealed core Guan Yuxin base with gear platform matches, gland is threaded on core base, core pipe is packed in core base, core pipe pore top is arranging ladder concave station, the bottom of pore is arranging screw, rotating shaft cooperation is arranged in pore, rotating shaft matches with the screw of core pipe by screw thread, stretching out the turbination spindle nose of installing on the rotating shaft axle bed of core pipe lower end matches with the hole circle in lower tube connector, the seal assembly of installing in the ladder concave station of core pipe pore coordinates with rotating shaft sealing, the pillar being fixedly mounted with in the upper end of core pipe is being fixedly mounted with the graduated metering seat of tool with rotating shaft and is matching, in the upper end of rotating shaft, be fixedly mounted with handle or handwheel.
According to the user demand to triplate line, the utility model is arranged on production tree production flow line,
By rotating handwheel, rotating shaft is moved up and down, make to form annular space area of passage between spindle nose and hole circle.
The scale that pointer place shows, represents the equivalent aperture diameter that annular transition face is long-pending.The size that can show intuitively flow channels, adjust flux fast, accurately.
Forward rotating shaft to bottommost, spindle nose can enclose in automatic centering hole, realizes preliminary closed condition.
In the time of need to the compression effect of seal assembly being regulated, be safeguarded, part more than pillar can be taken off, with special spanner rotatory sealing gland, other parts such as rotating shaft are unaffected.
In the time of need to making regular check on maintenance, open gland, directly take off seal plug; Hole seat takes out with sleeve metal plate hand.
Main body of the present utility model adopts tubing type structure, can with multiple pipeline or equipment connection, improve the degree of freedom that pipeline connects.
Spindle nose belongs to T shape with rotating shaft and is flexibly connected, and while closing, the centering better effects if of spindle nose reduces difficulty of processing simultaneously.Left and right, lower tube connector all adopts clamping hoop type to connect, metal ring sealing, and effective sealing connects fast.
When the compression effect of seal assembly is regulated, safeguarded, part more than pillar can be taken off, not need to dismantle other parts such as rotating shaft.
When the component such as hole circle are carried out to major tune-up, replacing, gland is taken off, available special spanner takes out inner body.
The utility model is rational in infrastructure, and performance safety is reliable, has realized multiple pipeline or equipment connection, and adjust flux quick and precisely, can show the size of flow channels intuitively, and uses, installs, safeguards easily.
