Abstract

The invention relates to the field of water conservancy pipeline valve body machining, in particular to a water conservancy pipeline stop valve assembling device. The invention aims to solve the technical problem of providing the water conservancy pipeline stop valve assembling device which can accurately and moderately assemble a stop valve and a gasket, and is in accurate in positioning and highin assembling efficiency. According to the technical scheme, the water conservancy pipeline stop valve assembling device comprises a bottom plate, a main rack, double shift levers and an air cylinder; and the bottom plate is arranged at the bottommost portion, the main rack is fixedly connected over the bottom plate, the air cylinder is fixedly connected to the uppermost end of the main rack, anda piston rod of the air cylinder penetrates through a baffle at the upper end of the main rack and extends downwards. According to the water conservancy pipeline stop valve assembling device, the aircylinder, a slotted pipe, a material taking and placing device and the like are additionally arranged, the air cylinder can complete the gasket taking action and the gasket assembling action after stretching out and drawing back by one cycle, and therefore the gasket assembling speed of the stop valve is greatly increased.

Description

technical field

[0001] The invention relates to the field of processing a valve body of a water conservancy pipeline, in particular to an assembly device for a stop valve of a water conservancy pipeline. Background technique

[0002] Globe valve, also known as cut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the disc, the resistance that the operating force needs to overcome is the friction between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve must be large, otherwise the failure of the valve stem to bend will occur. The tightness of the stop valve is particularly important, so the stop valve gasket must be installed correctly and moderately on the sealing surface, not de...
