Description
Technical Field
The utility model relates to the valve field, concretely relates to executor support that adjusting valve was used.
Background
The regulating valve is also called a control valve, and is operated by power to change the flow of the fluid by receiving a control signal output by the regulating control unit. The regulating valve generally consists of an actuator and a valve. If the power is used by the matched actuating mechanism, the regulating valve can be divided into a pneumatic regulating valve, an electric regulating valve and a hydraulic regulating valve, and in addition, the regulating valve is divided into three types, namely a linear characteristic, an equal percentage characteristic and a parabolic characteristic according to the functions and the characteristics of the regulating valve.
The regulating valve mostly adopts a straight stroke structure, namely a valve core does straight reciprocating motion, and the outlet flow value of the valve is regulated through the valve core at different positions, so that actuators used by the regulating valve are basically straight stroke actuators. In order to ensure the characteristic curve of the regulating valve, the regulating valve strokes of all specifications are different, so that the corresponding stroke value of the actuator is required, but when the actuator changes one stroke, the electrical components, the circuit board, the program and the mechanical part are required to be changed, the design is complicated, and the cost is high.
At present, in order to reduce the types of actuators, two strokes of 20mm and 40mm are mostly adopted in the market, so that the characteristic curve of the valve needs to be sacrificed to adapt to the actuators, and the problems of inaccurate characteristic curve and poor valve performance are caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems of the existing actuators, the actuator support for the angle stroke-to-straight stroke adjusting valve can change the angle stroke actuator into a linear stroke, the same actuator can change the stroke size only by changing the actuator support, the operation is simple, the change is convenient, the cost is low, and the problem of poor valve performance caused by few types of actuator strokes is solved.
The utility model adopts the technical proposal that: an actuator support for an angular travel-to-straight travel adjusting valve comprises a support body, an input shaft bearing, a change gear, an output shaft bearing, a support cover, an output shaft and a connecting shaft device, wherein the input shaft bearing and the output shaft bearing are respectively connected with the support body, the input shaft is arranged in the input shaft bearing, the output shaft is arranged in the output shaft bearing, the change gear is arranged on the input shaft, teeth matched with the change gear are arranged on the output shaft, the support cover seals the part, matched with the teeth of the output shaft, of the change gear in the support body to form a closed cavity, and the connecting shaft device connected with a valve rod is arranged on the output shaft.
Preferably, the number of the teeth of the change gear can be changed, the distance between the output shaft and the change gear is changed, and when the change gear rotates at the same angle, the moving distance of the output shaft is changed along with the change gear, so that the function of outputting different strokes by the same actuator is realized.
The utility model has the advantages that: simple structure, processing is convenient, only needs to change the number of teeth of the change gear and the distance with the output shaft, and same executor will have different output strokes to reach the function of the various stroke valves of adaptation, the change is convenient, the great reduction of cost.

Detailed Description
In order to make the purpose and technical solution of the present invention more clear, the present invention will be further described with reference to the accompanying drawings.
The actuator support comprises a support body 1, an input shaft 2, an input shaft bearing 3, a change gear 4, an output shaft bearing 5, a support cover 6, an output shaft 7 and a connecting shaft device 8, wherein the input shaft bearing 2 and the output shaft bearing 5 are connected with the support body 1, the input shaft 2 is arranged in the input shaft bearing 3, the output shaft 7 is arranged in the output shaft bearing 5, the change gear 4 is arranged on the input shaft 2, teeth matched with the change gear 4 are arranged on the output shaft 7, the support cover 6 seals the part, matched with the teeth, of the change gear 4 and the output shaft 7 in the support body 1 to form a closed cavity, and the connecting shaft device 8 connected with a valve rod is further arranged on the output shaft 7.
The support body 1 is connected with an angle stroke actuator, the angle stroke actuator transmits power to the change gear 4 through the input shaft 2, the change gear 4 changes the rotary motion of the change gear 4 into the linear motion of the output shaft 7 through teeth on the output shaft 7, and the output shaft 7 transmits the linear motion to the valve through the connecting shaft device 8.
By changing the number of teeth of the change gear 4 and the distance between the change gear and the output shaft 7, the moving distance of the output shaft 7 changes when the change gear 4 rotates at the same angle, and the function of outputting different strokes by the same actuator is realized.
