Abstract
The utility model relates to a manual speed reducer for a valve. The manual speed reducer for the valve comprises a shell body, a shell cover, a fan-shaped worm gear, a worm and a stamping hand wheel. Worm gear bases are arranged in the middle of the shell body and in the middle of the shell cover respectively. The fan-shaped worm gear is arranged in the shell body. A working hole is formed in the swing central position of the fan-shaped worm gear. Positioning bosses are arranged on the outer sides, at the two ends of the working hole, of the working hole. The positioning bosses are arranged in corresponding worm gear bases respectively. A worm base is arranged on the edge of one side of the shell body in the tangential direction. The worm is arranged in the worm base. A meshing part of the worm is meshed with the fan-shaped worm gear. The stamping hand wheel is arranged at an extending end of the worm. The shell cover is installed on the shell body in a buckled mode. According to the technical scheme, moving control is replaced by rotating control for controlling the valve, the force which is needed for opening and closing the valve is lowered, the opening degree of the valve can be controlled accurately, and the opening position of the valve can be indicated; moreover, the manual speed reducer for the valve has a quite good self-locking effect, and is low in weight, and small, exquisite and beautiful in appearance.
Description
Technical field
The utility model relates to the opening device that a kind of valve opening is used, and particularly relates to the manual retarder of a kind of valve.
Background technique
In the prior art, all be the opening and closing that realize valve with handwheel or the direct rotating valve of handle, and come the aperture size of control valve by the difference of rotation angle that there is following defective in this kind mode:
1. manually opened effort in the prior art, aperture size are difficult to control.
2. when valve is subjected to big flow attack, change the enable possition easily, thereby cause changes in flow rate.
The model utility content
In view of this, main purpose of the present utility model is to provide a kind of valve manual retarder, pass through the technical program, to move and be controlled to be the rotation control valve, greatly reduce the dynamics of opening and closing valve, and the unlatching size of control valve more accurately, and have self-locking effect preferably, outward appearance is small and exquisite beautiful.
In order to achieve the above object, the technical solution of the utility model is achieved in that the manual retarder of a kind of valve, include housing and cap, described housing and cap are formed by aluminium die-casting, also include worm sector, worm screw and punching press handwheel, the middle part of described housing and cap is respectively arranged with the worm gear seat, described worm sector is arranged in the housing, oscillation center position at worm sector is provided with working hole, working hole arranged outside at the working hole two ends has positioning boss, described positioning boss is separately positioned in the corresponding worm gear seat, the working hole axial direction is provided with the work keyway in described working hole inwall upper edge, the tangent direction of one side margin of described housing is provided with the worm screw seat, described worm screw is arranged in the worm screw seat, engagement position on the described worm screw is meshed with worm sector, and the punching press handwheel is arranged on the external part of worm screw, and described cap spiral-lock is on housing.
Be positioned on the described housing on the symmetrical position of worm screw and be respectively arranged with spacing screw, be installed with spacing screw rod in spacing screw, when worm sector swung to limit position, the lower end of two spacing screw rods was pressed on respectively on the side, both sides of worm sector.
Be positioned on the positioning boss of cap one side and be set with the rotation capping, rotate capping and be provided with indicating arrow, the corresponding cap of indicating arrow is provided with valve opening position scale line.
Worm screw seat arranged outside has oil sealing on the housing of worm screw external part one side.
Beneficial effect after the employing technique scheme is: the manual retarder of a kind of valve, adjustment configuration by the technical program and technical parameter, to move and be controlled to be the rotation control valve, output torque increases greatly in product of the same type, greatly reduce the dynamics of opening and closing valve, and the unlatching size of control valve more accurately, indicate the valve opening position, and have self-locking effect preferably, weight is slim and graceful, outward appearance is small and exquisite beautiful.
