The utility model provides a but butt clamp formula handle butterfly valve that emergency closed simple structure uses more convenient and more reliable in the valve use.
Description
Technical Field
The utility model relates to a valve field especially relates to the wafer formula handle butterfly valve that can emergent close.
Background
The valve is a pipeline accessory used for opening and closing a pipeline, controlling the flow direction, adjusting and controlling parameters of a conveying medium, and can be divided into a shut-off valve, a check valve, a regulating valve and the like according to the functions of the valve, wherein the valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing backflow, stabilizing pressure, shunting or overflowing and relieving pressure and the like, the valve used for the fluid control system is a valve from a simplest stop valve to various valves used in a very complicated automatic control system, the variety and the specification of the valves are quite various, the clamp type handle butterfly valve is widely applied due to simplicity and convenience in the use process, the problems of aging and even damage of parts cannot be avoided in the use process, the handle of the clamp type handle butterfly valve is exposed in the environment in a protruding mode and has a high damage probability, when the handle is damaged or is disconnected with a valve rod in the use process of the clamp type handle butterfly valve, the valve plate cannot be closed or opened, resulting in property loss.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that when providing handle damage or its and valve rod disconnection, the still usable butt clamp formula handle butterfly valve that can meet an urgent need of valve closed.
The utility model discloses a realize through following technical scheme:
but the butt clamp formula handle butterfly valve that emergency closed, including valve body and valve rod, be provided with the brake disc of arc structure on the valve body, be provided with the slide rail on the brake disc, the slide rail is for using the arc that the valve rod is the center pin runs through the groove structure, be provided with in the slide rail along the radial direction can freely gliding screw thread handle, threaded connection has brake nut on the screw thread handle, the head end of screw thread handle is connected the top of valve rod, the end of screw thread handle is provided with handle, its characterized in that: the valve rod runs through the bottom of the valve body, a boss is arranged at the bottom end of the valve rod, and the boss is of a polygonal structure protruding in the radial direction.
Further, the handle is of a cylindrical structure made of polypropylene resin.
Furthermore, the number of the brake nuts is two, and the two brake nuts are symmetrically arranged along the slide rail.
Beneficial effects of the utility model
The utility model provides a but valve rod of the wafer formula handle butterfly valve that emergency shut off runs through the bottom of valve body and forms the boss of the bellied polygonized structure of radial direction in the bottom, and when the handle damaged or its and valve rod disconnection, use the rotatory boss of spanner or other instruments, can drive the valve plate and rotate the function that realizes the urgent opening and close of valve.
Furthermore, the handle is of a cylindrical structure made of polypropylene resin, and the polypropylene resin is used as an environment-friendly material, so that the pollution to the environment is avoided.
Furthermore, the number of the two brake nuts is two, the two brake nuts are symmetrically arranged along the sliding rail, when one brake nut slides, the other brake nut can be put into use, and the situation that the valve cannot work is avoided.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1, a valve body, 2, a brake disc, 3, a sliding rail, 4, a brake nut, 5, a threaded handle, 6, a handle, 7, a valve rod and 8, a boss are arranged.
Detailed Description
As shown in figure 1, the utility model provides a but opposite-clamping formula handle butterfly valve that emergency closed provided, be equipped with the brake disc 2 of arc structure on the valve body 1, be equipped with the slide rail 3 that the arc that uses valve rod 7 as the center pin runs through the groove structure on the brake disc 2, be equipped with in the slide rail 3 along the free gliding screw thread handle 5 of radial direction, threaded connection has brake nut 4 on the screw thread handle 5, and set up two along slide rail 3 symmetry, the head end of screw thread handle 5 is connected at the top of valve rod 7, the end of screw thread handle 5 is equipped with the handle 6 of the cylinder structure of polypropylene resin material, valve rod 7 runs through the valve body 1 bottom and is equipped with radial direction bellied polygon structure's boss 8 in its bottom, when wanting to change the butterfly valve state, stir screw thread handle 5, it drives valve rod 7 rotation and realizes the control flow, when the flow is suitable, twist brake nut 4 to support tightly on slide rail 3, at this time, the screw handle 5 can not move relative to the brake disc 2 any more, the position of the valve rod 7 is fixed, and the flow rate is stable and unchanged.
The working mode is as follows: when the screw thread handle 5 damaged or it and valve rod 7 disconnection, used spanner or other instrument rotatory boss 8, boss 8 drove valve rod 7 rotatory, and valve rod 7 control valve plate normally opens and close, accomplishes the utility model discloses the function of emergent closing.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
