Description
Technical field
The utility model relates to the regulating valve of using on the aerodynamic investigation pilot system pipeline.Belong to technical field of valve manufacturing.
Background technique
The chink type ring-type modulating valve that surges is a kind of valve that the aerodynamic investigation wind tunnel test system uses always, reaches the purpose of regulating working medium flow and pressure by the circulation area that changes valve.Existing chink type ring-type modulating valve is mainly by valve body, valve seat, sleeve, parts such as spool, displacement transducer, servo-cylinder and transmission device are formed, there is more defective, mainly show as: the valve seal auxiliary structure is simple soft sealing structure, can not effectively resist medium to the washing away of seal ring, and valve seat is fixed on the valve body, in use O-ring seal damages easily, need often to change, manipulate inconvenience; Valve body is a single layer structure, and when medium flowed by valve inner, because the valve inner part is more, and structure was various, easily produces turbulent flow and noise, and energy loss is big; Servo-cylinder and transmission device are located at the valve body outside, need drive valve core movement by linkage mechanism, complex structure; Original displacement transducer is more single, and measuring accuracy is not high.
The model utility content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, provides a kind of simple in structure, stable, the reliable chink type ring-type of the sealability modulating valve that surges.
The surge formation of modulating valve of the chink type ring-type that realizes the utility model purpose comprises valve body, valve seat, spool, the sealing pair structure, displacement transducer, servo-cylinder, it is characterized in that the double-deck valve body of described valve body for forming by inner casing and shell, the front end of valve body inner casing has the motion guide section of one section spool, the rear portion of valve body inner casing is connected with a sealed mode air guide sleeve, described servo-cylinder is installed in the valve body inner casing, spool is fixed on the servo-cylinder shell, be connected to a servovalve at the servo-cylinder piston end, described displacement transducer is by horizontal displacement sensors, the vertical displacement sensor is served as jointly, and described sealing pair structure is by the dovetail groove that is arranged on the valve base sealing end face excircle, be embedded in the soft seal circle in the dovetail groove, the hard sealing surface and the corresponding hard sealing surface that is arranged on the spool that are arranged on the dovetail groove upper end constitute.
The utility model is double-deck valve body with original single-beat valve structural reform, the rear portion of valve body inner casing connects a sealed mode air guide sleeve, the cavity that makes valve body inner casing inner chamber form sealing is installed servo-cylinder, guaranteed the flowing medium smooth flow on the one hand, solved the defective that the single layer structure fluid oscillation is big, energy loss is big, noise is big, remove the linkage mechanism of original drive valve core movement simultaneously, simplified the structure greatly, reduced the occupation of land space; The soft or hard double sealing structure guarantees the reliability of sealing; The displacement transducer of different azimuth setting has the function of double insurance.
Characteristics such as compared with the aforementioned existing similar products, the utlity model has simple in structurely, operate steadily, flexibly, Installation and Debugging are convenient, and Flow-rate adjustment is accurate, and sealability is reliable, the life-span is long, and the hydraulic system response rapidly, the displacement signal reaction is accurate quick.Through facts have proved, this modulating valve can satisfy the requirement of aerodynamic investigation system test fully.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Embodiment
Shown in Fig. 1～2, the surge double-deck valve body of valve body for being made up of inner casing 13 and shell 4 of modulating valve of this chink type ring-type supports wing plate 14 by streamline between the inside and outside shell and connects the formation medium runner.The front end of valve shell is connected with valve seat 1, and the front end of valve body inner casing 13 has the motion guide section 15 of one section spool 3, and the rear portion of valve body inner casing 13 is connected with a sealed mode air guide sleeve 12.Servo-cylinder 5 is installed in the valve body inner casing by the mode that at valve body inner casing middle part supporting frame 6 is set, servo-cylinder is fixed in the above.Spool 3 is fixed on the servo-cylinder shell, and its outer surface kink is in motion guide section 15.Servovalve 7 is fixed on the servo-cylinder piston end.On supporting frame 6, be fixed with a displacement supporting frame 8 for sensor installation, one end of horizontal displacement sensors 11 is fixed on the air guide sleeve 12, the other end inserts in the displacement supporting frame 8, and an end of vertical displacement sensor 10 is fixed on the valve body, and the other end inserts in the transmission rod 9.Transmission rod 9 is connected between the inclined-plane of valve body and displacement supporting frame.Referring to Fig. 3, soft seal circle 2 is embedded in the dovetail groove 16 that is arranged on the valve base sealing end face excircle, seals between spool, valve body and valve seat.Being arranged on the hard sealing surface 18 of dovetail groove upper end can constitute according to the different alloy material of different seal request built-up welding with hard sealing surface 17 on being arranged on spool.
The same with prior art, pass through external HPS input signal during work, oil pump begins fuel feeding, and commander's servovalve 7 control servo-cylinders 5 motions, promote the to-and-fro motion of oil cylinder outer cylinder sheath, drive spool 3 to-and-fro motion that are connected on the outer cylinder sheath simultaneously, change the circulation area of medium, realize the requirement of regulating valve flow, pressure; During valve closing, the hard sealing surface 17 of spool at first contacts the soft seal circle 2 on the valve seat, realizes reliable soft seal shutoff, reaches the seal request of soft seal; After the soft seal circle was compressed or weares and teares, the hard sealing surface 17 on the spool contacted with hard sealing surface 18 on the valve seat, and valve can continue reliable sealing.The stroke of spool 3 passes to horizontal displacement sensors 11 and vertical displacement sensor 10 by displacement supporting frame 8 with the displacement signal of spool.Vertical displacement sensor 10 can be fitted on the inclined-plane of displacement supporting frame by roller always, and the variation of the bevel altitude of displacement supporting frame 8 passes to vertical displacement sensor 10 by transmission rod 9, and vertical displacement sensor 10 is exported with digital signal after the signal processing; Horizontal displacement is directly provided by moving horizontally of displacement supporting frame 8, the Horizontal displacement signal is directly passed to horizontal displacement sensors 11, horizontal displacement sensors with signal processing after, export with digital signal, the travel position information of valve accurately is provided fast, realizes all functions that modulating valve is predetermined.Even under the situation that a displacement transducer lost efficacy, do not influence the reaction of stroke yet, have the function of double insurance.
Referring to Fig. 4, described spool can be designed as the combination valve core that is connected to form by bolt 21 by spool liner 19 and spool overcoat 20.The benefit of making like this is to alleviate the weight of spool by changing the combination of materials of spool liner and spool overcoat.
