Problems solved by technology

[0004] However, in the above-mentioned filter valve, only one filter core is fixed in the sewage branch pipe, the flow velocity of the medium is faster when it enters the valve body, and the impurities mixed in the medium have the same flow velocity as the medium, so when the medium passes through the filter net, the impurities are in the Under the action of the flow velocity, it can also partly pass through the filter screen with the medium, which leads to unsatisfactory filtering effect and insufficient practical value.

Embodiment 1

[0026] like figure 1 and figure 2 As shown, a filter valve includes a valve body 1 with two ends respectively being a water inlet 2 and a water outlet 3, and a filter tube 4 is also provided on the valve body 1, and the water outlet 3 and the water inlet 2 of the valve body 1 pass through the filter The tubes 4 communicate with each other, the filter tube 4 is inclined relative to the valve body 1 and the filter tube 4 and the valve body 1 are in an integrated structure.

[0027] The filter pipe 4 is fixed with a coarse filter screen 5 and a fine filter screen 6, the coarse filter screen 5 is set outside the fine filter screen 6, the coarse filter screen 5 and the fine filter screen 6 are in a regular grid shape and the thickness of the coarse filter screen 5 The meshes are larger than the meshes of the fine filter screen 6 . The valve body 1 has a positioning seat 7 at the inner port of the filter tube 4, the inner end of the coarse filter screen 5 leans against the positi...

Embodiment 2

[0032] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: image 3 As shown, the blowdown member in this embodiment also includes a blowdown valve 14 that is threadedly connected with the gland 9 , and the blowdown valve 14 is a ball valve and communicates with the filter pipe 4 . By setting a blowdown valve 14 connected with the filter pipe 4, when the impurities in the filter pipe 4 accumulate more, it is not necessary to unscrew the gland 9, and the blowdown can be carried out quickly only by opening the blowdown. Close the drain valve 14 and get final product. Of course, when cleaning or replacing the filter screen, the drain valve 14 needs to be unscrewed together with the gland 9 .

Abstract

The invention provides a filter valve, which belongs to the technical field of machinery, and solves the problems of unsatisfactory filtering effect and low practical valve of a conventional filter valve. The filter valve comprises a valve body with a water inlet and a water outlet formed in two ends, wherein the valve body is provided with one filtering pipe for allowing the valve body water inlet and the valve body water outlet to be communicated; an outer end of the filtering pipe is connected with a sewage draining piece; a rough filter screen and a fine filter screen are fixed in the filtering pipe; the rough filter screen is sleeved with the fine filter screen; the rough filter screen and the fine filter screen are all regular grid shape, and mesh of the rough filter screen is greater than that of the thin filter screen. The filter valve has the advantages of simple structure, good filtering effect, high practical value, and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a filter valve, in particular to a filter valve with double-layer filter nets. Background technique [0002] The filter valve is a device for filtering pretreatment, and it is also an indispensable device for the pipeline series of conveying media. It is usually installed at the inlet end of hydraulic control valves, pressure reducing valves, pressure relief valves, constant water valves and other equipment. Eliminate impurities in the medium, prevent granular impurities from entering the channel, and cause blockage, so as to protect the fittings on the equipment pipeline from wear and blockage. [0003] Filter valves are widely used in industrial production and daily life. Existing filter valves include components such as a valve body, a valve cover, and a filter core. The valve body includes an inner cavity with an inlet and an outlet and a branch pipe. For example, a Chinese ...
