Description
Technical Field
The utility model relates to a valve, in particular to have aperture to instruct can stabilize the choke valve of regulation flow.
Background
The shape of the throttle valve is not different from that of the shut-off valve, except for the shape of the opening and closing member. The throttle valve is usually of a conical streamline shape, and the flow and pressure can be adjusted by changing the cross section of the channel. The throttle valve serves to reduce the pressure of the medium in the event of a very large pressure drop.
When the existing manual throttle valve is used for flow regulation of a pipeline system, two problems are usually encountered, namely, the opening degree of a valve clack cannot be known accurately when the flow regulation is carried out; when the valve clack is in a partially opened state, the valve rod can only be positioned by the aid of the threads, the valve clack vibrates due to fluid flowing through the valve clack, and therefore the valve rod positioned by the aid of the threads loses self-locking capacity of the threads, opening degree of the valve clack is changed, and the existing throttling valve cannot be suitable for harsh use working conditions.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a have the aperture to instruct can stabilize the choke valve of regulation flow, this choke valve can observe the aperture of valve clack and guarantee that the aperture of opening of valve clack can not change to be applicable to harsh use operating mode.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a have aperture to instruct can stable regulation flow's choke valve, includes the valve body, sets up in valve gap, the screw thread of valve body and installs in the valve rod of valve gap and install in valve rod and cooperation valve body formation sealed valve clack, including the locking member who is used for the real-time aperture of locking valve rod, install the instruction piece along with the valve rod motion on the valve rod, be equipped with the aperture indicator that the cooperation instruction piece is used for observing the valve clack aperture on valve body or the valve gap.
Through adopting above-mentioned technical scheme, the valve rod drives the instruction piece synchronous motion at the pivoted in-process, and through the instruction piece of observing after the displacement and contrast the scale on the aperture indicator, the staff can be clear knows the aperture of locating of valve rod. After the valve clack is rotated to the required opening degree, the valve rod is locked in real time through the locking member, so that the opening degree of the valve clack is fixed and cannot be changed, and the valve can be suitable for harsh use working conditions.
Further setting the following steps: the locking member is disposed between the opening indicator and the indicating block.
Through adopting above-mentioned technical scheme, set up and realize the real-time locking operation to the valve rod between aperture indicator and instruction block.
Further setting the following steps: the locking member comprises a waist-shaped hole which is arranged on the opening indicator and extends along the axial direction of the valve rod, a threaded hole which is arranged on the indicating block and a locking screw which penetrates through the waist-shaped hole and is in threaded connection with the threaded hole.
By adopting the technical scheme, the locking screw penetrates through the waist-shaped hole and is in threaded connection with the threaded hole to limit the rotation of the valve rod, so that the opening of the valve clack is positioned in real time. Due to the fact that the kidney-shaped hole is matched with the locking screw, the height of the indicating block can be changed, the valve rod can be limited to rotate in real time, and the structure is simple and convenient.
Further setting the following steps: the threaded holes are arranged in a plurality of surrounding modes around the circle center of the valve rod.
Through adopting above-mentioned technical scheme, the aperture position of regulation valve clack that the setting of a plurality of screw holes can be more accurate to promote the quality of valve.
Further setting the following steps: and the valve rod is fixedly connected with the indicating block.
Through adopting above-mentioned technical scheme, the mode of fixed connection makes the motion along with the valve rod that the instruction piece can be accurate.
Further setting the following steps: the sealing packing is arranged between the valve cover and the valve rod, the packing pressing sleeve used for extruding the sealing packing is arranged on the valve cover, and the packing pressing plate used for locking the packing pressing sleeve is arranged on the valve cover.
Through adopting above-mentioned technical scheme, the leakproofness between valve rod and the valve gap is guaranteed in the cooperation between sealing filler, gland and the packing clamp plate three, prevents to leak.
Further setting the following steps: the bottom of the valve clack is in a conical streamline shape protruding outwards.
By adopting the technical scheme, the valve clack in the shape can better adjust the flow and the pressure of a medium.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses can observe the aperture of valve clack and guarantee that opening of valve clack can not change to be applicable to harsh use operating mode.
