Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, the Y-type filter capable of backwashing and quick sewage discharge of the present invention includes a filter body 1 and a screen cartridge 3. The filter body 1 has three ports in total, namely a fluid inlet 11 , a fluid outlet 12 and a sewage outlet 13 . The fluid inlet 11 is thread-tightly connected with the inlet ball valve 4, the sewage outlet 13 is thread-tightly connected with the transition joint 2, the other end of the transition joint 2 is thread-tightly connected with the sewage ball valve 5, and the filter cartridge 3 is installed in the filter body 1. In the cavity 10, the diameter of the sewage outlet 13 can be enough to take out the filter screen 3 cylinders, so that when the filter screen cylinder 3 breaks down, the filter screen cylinder 3 can be taken out from the sewage discharge port for replacement, and the inner diameter of the transition joint 2 is smaller than the diameter of the filter screen cylinder 3....

Abstract

The invention provides a Y-shaped filter capable of realizing backwashing and quickly discharging sewage. The Y-shaped filter comprises a filter body (1) and a filter screen cylinder (3) installed inthe filter body (1), an inlet ball valve (4) is installed on a fluid inlet (11) of the filter body (1), and a sewage draining exit (13) of the filter body (1) is connected with a sewage draining ballvalve (5) through a transition joint (2). According to the Y-shaped filter capable of realizing backwashing and quickly discharging sewage, the inlet ball valve and the sewage draining ball valve aremounted, so rapid backwashing and sewage draining of the Y-shaped filter can be realized; therefore, a plug and the filter screen cylinder do not need to be disassembled when impurities are removed from the Y-shaped filter, a series of problems caused by disassembling and assembling of the filter screen cylinder are reduced, and pollution discharge efficiency and quality are improved.

Description

technical field [0001] The present invention relates to a filter device, in particular to a filter for pipelines, pumps and the like. Background technique [0002] Y-type filter is an indispensable filter device for the pipeline system of conveying medium. Y-type filter is usually installed at the inlet of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to remove impurities in the medium. , to protect the normal use of valves and equipment. The Y-type filter has the characteristics of advanced structure, small resistance and convenient sewage discharge. The applicable medium of Y-type filter can be water, oil and gas. Generally, the water mesh is 18-30 mesh, the ventilation mesh is 10-100 mesh, and the oil mesh is 100-480 mesh. For example, in the existing residential heating system, the general household main pipe is equipped with a Y-shaped filter to remove impurities in the medium to protect the normal use of the indoor heatin...
