A filter valve with a rotating inner core

Abstract

The invention discloses a filter valve provided with a rotary inner core. The filter valve comprises a cylindrical valve body, wherein a water inlet end and a water outlet end are respectively arranged on two sides of the outer wall of the valve body; a circle of filter screen is arranged on the inner wall of the valve body; a filter core is arranged in the filter screen; the filter core is connected to a rotating shaft in a sleeving manner; the rotating shaft is arranged in the center of the valve body; the upper end of the rotating shaft is screwed onto a valve cover; the valve cover is connected to the top end of the valve body in a clamping manner; a layer of sealing rubber ring is arranged at a position, which is in contact with the inner wall of the upper part of the valve body, of the rotating shaft; a blowdown outlet is formed in the bottom of the valve body; a blowdown tank is arranged on the bottom of the blowdown outlet in a screwed manner. According to the filter valve provided with the rotary inner core, the filter inner core which is capable of rotating is arranged inside the valve body, so that the filtering effect is good; the blowdown outlet and the blowdown tank are arranged, so that the washing period of the filter inner core can be prolonged. The filter valve has a favorable application prospect.

Description

technical field [0001] The invention relates to a filter valve provided with a rotating inner core, belonging to the technical field of valve body components. Background technique [0002] The filter valve is a filter pretreatment device, which is a necessary filter equipment for hydraulic control valves and precision mechanical products that are easy to clog. However, the filter core in the existing filter valve body is fixed in the valve body, and the filter effect cannot be rotated Not good, moreover, it is inconvenient to discharge sewage, and the filter core needs to be replaced and cleaned frequently, which takes a lot of time and effort. Contents of the invention [0003] The technical problem solved by the present invention is that the filter inner core in the traditional filter valve body is fixed in the valve body, which cannot be rotated and the filtering effect is not good, and it is inconvenient to discharge sewage, and the filter core needs to be replaced and...
