A handleless filter gate valve

Abstract

The invention relates to a handle-free filtration gate valve. The handle-free filtration gate valve comprises a rotary casing, valve cores and filter screens, wherein valve cores are used for being connected with a pipeline; two rotary baffles are mounted in an inner cavity of the rotary casing, and a through hole or a notch is formed in each of the rotary baffles; the valve cores are separately mounted at the end parts of the rotary casing; each of the valve cores comprises a connecting port which is used for sleeving the end part of the pipeline, a fixed sleeve and a fixed baffle; each of the connecting ports is in screwed connection with each of the fixed sleeves; the fixed sleeves are inserted into the end part of the rotary casing in a sealing manner; the fixed baffles are mounted on the inner end surfaces of the fixed sleeves in a sealing manner; the end surfaces of the fixed baffles are in sealing attachment with the end surfaces of the rotary baffles on the same side; the edges of the filter screens are fixedly connected with the inner walls of the fixed sleeves; the through holes or the notches in the fixed baffles correspond with those in the rotary baffles. The handle-free filtration gate valve disclosed by the invention has the beneficial effects that through the matching of the rotary casing and a rolling body, the action of opening and closing the valve under the handle-free condition is realized. A fixer can enable the valve cores to be axially positioned and provide guiding effects for the rotary casing; the handle-free filtration gate valve is simple and beautiful in appearance.

Description

technical field [0001] The invention relates to a handleless filter gate valve. Background technique [0002] At present, the existing pipeline gate valve is mainly composed of valve core, valve stem, valve body and handle. According to the classification of the valve core, it can be divided into ball valve, gate valve, butterfly valve, cylindrical valve, etc., and can be divided into stop valve and check valve according to its function. valve, diverter valve, safety valve, filter valve, etc. Its working process is to drive the valve core to move by rotating the handle (handle type or wheel type) to complete the opening and closing of the valve. At present, the existing gate valves are all controlled by a handle protruding from the outside of the valve body. Such a structural design requires a large rotating space during the working process, and the filter screen of the filter valve is installed sideways. And in the installation process, especially in the pipeline installa...

Problems solved by technology

[0003] In order to overcome the problems of existing gate valves, such as difficulty in installation, difficulty in integrating filtering functions into the valve, and insufficient appearance, the invention provides a filter gate valve with a handleless straight cavity, which simplifies the protruding handle part and makes the appearance more beautiful. A new opening and closing device and a multi-action filter installed in the valve cavity
