The angle valve can achieve high-efficiency seal, step-down performance and free combination of internal parts; in addition, the anti-scour and anti-cavitation performances are excellent, and the angle valve can be controlled stably and reliably.

Description

High-pressure multi-stage step-down cage balance type angle valve
Technical field
The utility model relates to a kind of high-pressure multi-stage step-down cage balance type angle valve, is particularly suitable for using in High Pressure Difference industrial fluids, gas, gas-liquid mixed phase system, plays and regulates and the shutoff effect, belongs to the automatic control technology field.
Background technique
In the prior art, especially in industrial fluids power conduit system, valve is primary element of realizing whole system automation control.What its assurance system controlled is safe, instant and effective, and central topmost factor is the operation of pressure adjusting and flow control valve, and can not cause the infringement of valve body and system under any mode of operation.It is the problem place that this field domestic demand solves.
On conventional control valve especially high pressure angle valve, exist common problem to be: 1, under the High Pressure Difference situation, the multistage step-down spool of general double seat or multiple seat type sealing configuration sealability is difficult to guarantee that reason is will guarantee simultaneously relatively difficulty of two or more sealing surface performances under certain Stroke Control.2, under the High Pressure Difference situation, general double seat seal spool structure easily produces vibration under the washing away of fluid, and valve rod is easily broken.3, under high-pressure situations, the processing medium flow velocity is very fast, easily produces and washes away and cavitation phenomenon.4, under the High Pressure Difference situation, flow velocity is very fast, and vibrations are severe that adjusting function is all had very big influence, and noise is very big, serious environment pollution.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of high-pressure multi-stage step-down cage balance type angle valve is provided, and can realize efficient sealed, step-down performance; The optional internals of energy combination in any, protection against erosion air defense voltinism can be good especially, and control is steadily reliable.
The technological scheme that provides according to the utility model, high-pressure multi-stage step-down cage balance type angle valve comprises actuator, body, valve rod, loam cake, valve seat, valve body, actuator be installed in body on cover, connect by round nut, valve seat is installed on the valve body, feature is: the first throttle cover and second orifice sleeve are installed on the described valve seat, gland is pushed down the first throttle cover and second orifice sleeve, last sealing cushion for cover is installed between valve body and the gland, gimbal is installed in the groove of gland and first throttle cover, valve rod is threaded with valve plug, pin by straight pin, the Packing seat of packing into successively in the described valve body stuffing box, the filler spacer, filler on chip and thread filler are installed Gland and hold-down grid on the described thread filler successively, and hold-down grid is fixed by bolts to and covers.
Described valve plug sealing surface bottom is provided with guiding gutter.Described gimbal adopts metallic material or nonmetallic material to make.
Compared with the prior art the utility model has the following advantages:
The utility model is because the trim seal form adopts the sealing of single seat guiding type, guarantee that sealing surface can steadily contact, can play good sealing effect, soft seal can reach the VI level, hard sealing can reach V or VI level, the use of balance type trim simultaneously greatly reduces valve plug top and bottom pressure reduction, regulates control steadily, reduces vibration.
2, because the heap face seal is adopted in the sealing of trim seal valve seat, pilot seal replaces two-seater sealing in the past, because the soft seal that gimbal adopts metallic material to make hard sealing or adopt nonmetallic material to make, the multi-form gimbal of soft seal and hard sealing all can play good sealing effect.
3, because the sleeve that matches with valve plug in the design of internals adopts split type, valve seat adopts fast assembling ﹠ disassembling, easy for installation flexible, and can the orifice sleeve that quantity does not wait be installed according to specific requirement, the main step-down noise reduction effect that rises, also can play good effect to the anti-cavitation of vibrationproof, the sleeve of different adjustment window can certainly be installed according to different control characteristics.
4, owing to be provided with guiding gutter in valve plug 14 sealing surface bottoms, require to be provided with the guiding gutter that population size does not wait according to different pressure reduction, though through the medium of orifice sleeve throttle orifice by step-down but speed is still very fast, easily spool valve body is washed away, the effect of guiding gutter at this moment just is to change the flow direction of medium, makes it at the certain swirling flow consumed energy of the inner formation of runner.
