The valve body is a wedge-shaped rubber body molded on the rib plate, the contact surface of the valve body and the nozzle of the short valve pipe is a plane, and the back surface of the valve body is a transition cambered surface. The short valve pipe is a metal pipe with one end being reduced and is fixedly connected with the inlet cavity of the valve body. The necking end is in effective seal with the valve body, and the necking of the short valve pipe reduces the acting area of the fluid on the supply side to the valve body, thereby reducing the acting force of the fluid on the valve body. The torque of the valve switch can be properly reduced through optimization, and the overall comprehensive performance of the electric valve is improved.

Description

Optimize structure of motorised valve switching moment of torsion

Technical Field

The utility model relates to an optimize structure of motorised valve switching moment of torsion.

Background

The diameter of the short valve pipe of the existing similar electric valve is an equal-diameter pipe with constant diameter, when the valve body and the short valve pipe are sealed, the pressure borne by the valve body is the product of the pressure of the fluid on the supply side and the area of the corresponding short valve pipe opening, the torque required by the electric valve to open and close the valve is determined by the pressure borne by the valve body, and how to reduce the energy consumption of the electric valve and improve the comprehensive performance of the valve is important for the electric valve with large flow or used in a pipe network with higher pressure.

Disclosure of Invention

The utility model discloses an on the basis of original motorised valve of the same kind, optimize the constant diameter valve nozzle stub for under the condition of equal pipe network pressure, can suitably reduce the moment of torsion of valve switch, if former motorised valve power configuration is unchangeable, then the abundance degree of switch valve moment of torsion increases, and switch valve's reliability just obtains promoting. The utility model discloses a realize like this, it comprises valve pivot, gusset, valve body, valve nozzle stub, valve body, the valve pivot for the metal ladder staff that is equipped with sealed slot, jump ring groove, be equipped with the metal gusset as mould pressing valve body inserts, adopt the riveted method that punches to consolidate between valve pivot and gusset, mould pressing valve body formation subassembly on the gusset again. The valve body is a wedge-shaped rubber body molded on the rib plate, the contact surface of the valve body and the nozzle of the short valve pipe is a plane, and the back surface of the valve body is a transition cambered surface. The short valve pipe is a metal pipe with one end being reduced and is fixedly connected with the inlet cavity of the valve body. The necking end is effectively sealed with the contact of the valve body, the necking of the short valve pipe reduces the acting area of the supplied side fluid on the valve body, thereby reducing the acting force of the fluid on the valve body, and the flow speed of the necking is accelerated when the valve is opened because the short valve pipe is locally necked, so the necking of the short valve pipe does not obstruct the stability of the rated flow. The valve body is a stepped through hole with internal threads at two ends, one end of the stepped through hole is tightly and fixedly connected with the short valve pipe, the middle part of the valve body is provided with a mounting hole which is perpendicular to the axis and used for mounting the rotating shaft of the valve and the valve body component, the mounting hole is provided with internal threads and a sealing ring shoulder, and the mounting hole is screwed and closed by a sealing cover after the rotating shaft of the valve and the valve body component are mounted. A rotating shaft mounting hole for mounting the valve rotating shaft is offset from the opposite surface of the valve body middle mounting hole, the valve rotating shaft is inserted into the rotating shaft mounting hole from the valve body middle mounting hole during mounting and is locked by a clamp spring, the valve rotating shaft can freely rotate in the rotating shaft mounting hole, and the exposed part of the valve rotating shaft in the valve body is connected with a motor transmission part.
