Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of Novel oil gas throttle valve.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow, by throttle valve and one-way valve parallel connection capable of being combined become one-way throttle valve, throttle valve and one-way throttle valve are easy flow control valves, in hydraulic system with constant displacement pump, throttle valve and relief valve coordinate, can form three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil circuit Metering Flow Control Circuits and bypass throttling speed governing system.
Well head throttle valve is mainly for the production of throttling, for controlling flow, optimizes and produces, and can reduce well head pressure to can applying pressure scope.Also can be used for noting well throttling and drilling well throttling.The main operative norm of well head throttle valve is API Spec 6A or GB22513-2008, the common working environment very severe of throttle valve, in the environment of height erosion, high pressure (maximum pressure can reach 20000psi), high temperature, CO2 and H2S corrosion, work for a long time, therefore, throttle valve is shorter working life, general by the difference of its environment, the shortest only two weeks of working life, the time about half a year that also only can reach that working life is the longest.From working principle and the Environmental Conditions analysis of throttle valve, adopting at present in two ways can be for increasing the working life of throttle valve, the one, change throttle-valve structure, adjust MEDIA FLOW to, control media reduces medium to the erosion direction of pressure control part and the erosion of part is reached to the object that increases working life, lot of domestic and international producer all adopts this mode to improve the life-span of throttle valve now, needle regulator from nineteen twenty-five develops into present cage cover type throttle valve, diaphragm-type throttle valve and plug type throttle valve are also there is during this period, in the recent period, also some producer has developed mazy type throttle valve, by these improvement, the life-span of throttle valve has also obtained certain lifting, but improve and make throttle-valve structure complexity like this, be unfavorable for field maintenance.The 2nd, improve the material of pressure control part, the hardness that improves material directly strengthens part in abrasion-resistance, the mode of original adoption surface overlaying cobalt-based or nickel-base alloy improves part surface hardness, part surface hardness can be brought up to 45～60HRC, but actual effect is undesirable, then adopt again whole hard alloy to make pressure control part, its life-span has had and has significantly improved, but be limited by throttle valve cost, effective sale effect neither be too desirable.Less for controlling the fitting surface of uninterrupted between the spool of throttle valve and valve seat in addition, easily wearing and tearing, thus reduce its stable and sealability.
Separately there is China Patent No. to be: 201310375420.3 disclose a kind of throttle valve, particularly a kind of eccentric throttle valve.Concrete lower technological scheme is: a kind of eccentric throttle valve, include valve body, valve gap, spool, valve rod and driving mechanism, valve body is provided with medium inlet passage, medium flow pass and connection chamber, in connection chamber, be provided with the spool of throttle valve, medium inlet passage and medium flow pass are vertical setting, between connection chamber and medium flow pass, be provided with valve seat, this valve seat is embedded in medium flow pass, and valve seat is provided with the attachment hole that impels connection chamber and the conducting of medium flow pass, spool is seal disc, seal disc is provided with eccentric pod apertures, eccentric pod apertures is with the rotation of seal disc and the attachment hole coincidence conducting of valve seat or separate closure, between spool and valve rod, be provided with the rotating disk fork that impels valve core rotation, rotating disk fork is connected with the axle center of spool, between rotating disk fork and valve rod, be provided with current stabilization assembly.Structure in technique scheme between spool and valve seat is comparatively complicated, and especially sealability is also poor.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of Novel oil gas throttle valve, and this Novel oil gas has improved working life with throttle valve, has strengthened greatly the sealability of throttle valve simultaneously.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Novel oil gas throttle valve, comprise valve body, valve gap, valve rod, spool, and valve seat, described valve body is provided with medium flow channel and medium flow pass, described medium flow channel and medium flow pass are vertical setting, described valve seat is embedded in medium flow pass, one end of described valve rod is passed valve gap and is extended to outside valve gap and is connected with driving handle, the other end of valve rod connects spool, described spool coordinates control media flow under the driving of valve rod with valve seat, it is characterized in that: described spool is coniform, cone shape spool is inverted and is coordinated with valve seat, the outwardly formation flange in described inverted spool top, described flange lower surface is provided with seal ring, under the top of described valve seat, be recessed into step, while tightening valve rod, the flange of spool and step fitted seal.
Bottom in described valve seat is hollow cylindrical; Its top is the sealing surface matching with cone shape spool, and described sealing surface is horn-like, on described sealing surface, is embedded with wearing layer.
Described spool is that stupalith is made.
Described wearing layer is formed by compound PTFE teflon on rubber layer.
The utlity model has following advantage:
1, in the utility model, spool is coniform, cone shape spool is inverted and is coordinated with valve seat, the outwardly formation flange in described inverted spool top, described flange lower surface is provided with seal ring, under the top of described valve seat, be recessed into step, while tightening valve rod, the flange of spool and step fitted seal, the outwardly formation flange in inverted spool top is as the brim of a hat, under the top of valve seat, be recessed into step, while tightening valve rod, the seal ring of the flange lower surface of spool and step fitted seal, strengthened the sealing of this oil gas throttle valve in the time closing.
