Description

Integral flange stop valve body forging

Technical Field

The utility model relates to a valve component, in particular to a valve body forging of an integral flange stop valve.

Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the sealing surface not to leak. When the medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force between the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur.

Valves are used in a wide variety of applications, such as in emergency pipelines where many valves are manually opened to ensure the reliability of the valves. When the sudden fire causes that an operator cannot reach the position of the valve to open the valve, secondary accidents are easily caused, and therefore greater potential safety hazards exist.

Further setting the following steps: including being formed at urgent passageway and cooperation valve clack formation sealed disk seat, the disk seat is located directly over the valve clack, the disk seat is separated into urgent flow channel and urgent flow channel of going into with urgent passageway, the urgent flow channel of going into communicates the one end of disk seat and is located directly over the valve clack.

By adopting the technical scheme, the valve seat and the emergency inflow channel are arranged above the valve clack, so that the acting force for opening the valve clack is combined with the fluid pressure and the gravity of the valve clack, the valve clack is ensured to be stably and quickly opened, and the stability of the structure is ensured.

Further setting the following steps: the end, back to the second lockhole, of the first lockhole and the end, back to the first lockhole, of the second lockhole are respectively provided with a plug, two elastic connecting strips are connected between the plugs, and the plug limiting locking pieces are located in the first lockhole and the second lockhole simultaneously.

Through adopting above-mentioned technical scheme, the setting up of end cap ensures that the locking piece is spacing in first lockhole and second lockhole by stable, prevents that the locking piece from appearing unexpected the dropping to avoid unexpected emergence. The elastic connecting strip facilitates the installation and the disassembly of the two plugs and can prevent the two plugs from falling off.

Further setting the following steps: the valve body is internally detachably provided with a support frame, and a through hole for the valve rod to pass through is formed in the support frame.

Through adopting above-mentioned technical scheme, braced frame's setting plays further bearing effect to the atress on the valve rod to promote the structural strength of valve rod installation, prolong the life of valve rod.

Further setting the following steps: the valve body is internally provided with a mounting groove, and the supporting frame is embedded in the mounting groove.

Through adopting above-mentioned technical scheme, the setting of mounting groove is fixed a position the installation to braced frame, makes the equipment operation more convenient.

In conclusion, the utility model has the following beneficial effects: the utility model can realize the emergency opening of the valve when a fire disaster happens, thereby avoiding the occurrence of secondary accidents and avoiding the potential safety hazard.
