Embodiment Construction

[0015] As shown in the figure, an improved shut-off valve includes a valve body 1, a transition chamber 2 is provided on the valve body 1, an inlet channel 3 and an outlet channel 4 are respectively provided on both sides of the transition chamber 2, and the transition chamber 2. The inlet channel 3 communicates with the outlet channel 4. A layer of filter membrane 5 is provided on the inside of the outlet channel 4. A drainage channel 6 is provided at the bottom of the transition chamber 2. The drainage channel 6 is a cylindrical structure. The drainage channel 6 is parallel to the outlet channel 4 and is arranged opposite to the outlet channel 4. The drainage channel 6 is provided with a fixed plug 7, and the fixed plug 7 includes a fixed plug body 8, a fixed plug end cover 9 and a filter member 10 , the fixed plug main body 8 is a cylindrical structure, the fixed plug main body 8 is interference fit with the drainage channel 6, the fixed plug end cap 9 is a cylindrical struc...

Abstract

The invention relates to an improved cut-off valve, comprising a valve body, the valve body is provided with a transition cavity, and the two sides of the transition cavity are respectively provided with an inlet channel and an outlet channel, and the transition cavity, the inlet channel and the outlet channel are connected wherein, the bottom end of the transition cavity is provided with a drainage channel, the drainage channel is a cylindrical structure, the drainage channel is parallel to the outlet channel, and is arranged opposite to the outlet channel, and a fixed plug is arranged in the drainage channel , simple structure, can effectively filter out the impurities in the fluid flowing through the stop valve, safe and reliable, and at the same time increase the service life and save costs.

Description

technical field [0001] The invention relates to a stop valve. Background technique [0002] The opening and closing part of the stop valve is a plug-shaped disc, the sealing surface is flat or conical, the disc moves in a straight line along the center line of the valve seat, and the movement form of the valve stem also has a lifting and rotating rod type. Valves whose parts (disc) move along the center line of the valve seat, according to the movement form of the valve disc, the change of the port of the valve seat is proportional to the stroke of the valve disc, because the opening or closing stroke of the valve stem of this type of valve is relatively It is short and has a very reliable cut-off function, and because the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, this type of shut-off globe valve is very suitable as a cut-off valve. Or adjustment and throttling. [0003] However, i...
