Description

Rotary-core automatic drain filter

The utility model relates to a kind of rotary-core automatic drain filter that is used for hot water pipe net, metal conduit accessory class.

According to the requirement of nation-building portion, the newly-built heating residential hot water pipe net of China all will be designed to parallel system, and install hotlist additional, by chargeing with heat.For guaranteeing that hotlist normally moves, need before hotlist, add fixed filter, be used to tackle mechanical admixture in the pipeline, and with its timely eliminating.At present, the filter that hot water pipe net uses mainly contains y-type filter and automatic pollution discharge filter, but these two kinds of filters all belong to blowdown mode outside pipe, and y-type filter artificial unloading's blowdown regularly, though automatic pollution discharge filter energy automatic pollution discharge, but physical dimension is big, and is also not ideal from developing result, is not suitable for the preceding hot water of resident's building warmer hotlist and filters.

The utility model is at having a kind of core formula automatic pollution discharge filter that revolves that deficiency and the present heating pipe network of pipeline with the filter existence designs with the needs of hot metrology now, insert water pipe before this filter, following access valve (or other valves) also links to each other with return pipe, two screen packs are fixed on and revolve on the core, revolving the core framework cooperates with housing two screen packs is divided into two working chambers, backing plate and revolve on the core base plate symmetry and offer two breach, by revolving the joint operation of core and lower ball valve, can realize the backwash filter net at any time, and blowdown in return pipe, need not interim dismounting, clean hygiene, convenient and reliable, especially be fit to the preceding hot water of resident's building warmer hotlist and filter.

The purpose of this utility model can realize by following measures:

The utility model is positioned at before the hotlist, preceding access water pipe, and the below links to each other with return pipe by ball valve, and it includes housing parts, revolves core segment and operation part; Wherein housing parts comprises housing, cap; Revolve core within housing, include core frame, main filter screen and auxiliary filter screen; Below housing inward turning core, be provided with backing plate, can with revolve core and cooperate and form the filter drain outlet; The outer machined surface of core frame cooperates with working face on the interior machined surface of housing, the backing plate main filter screen and auxiliary filter screen is divided into two working chambers.When revolving core and be in position shown in Figure 2, the auxiliary filter screen working chamber communicates with following outlet, when the bottom ball valve is closed, come water to filter by main filter screen, outlet all flows to hotlist through a left side, being blocked the mechanical admixture that gets off then is deposited on the backing plate, if open ball valve this moment, filter outlet down is open-minded with return pipe, a water part of filtering through main filter screen flows to hotlist, part backwash auxiliary filter screen, as having impurity in the auxiliary filter screen chamber, it will be with outlet row under this part water warp to return pipe so; Lower ball valve is closed, to revolve core and turn clockwise 90 °, the main filter screen working chamber communicates with following outlet, outlet all flows to hotlist through a left side by the auxiliary filter screen filtration to come water, being blocked the mechanical admixture that gets off then is deposited on the backing plate, if open ball valve this moment, filter outlet down is open-minded with return pipe, a water part of filtering through auxiliary filter screen flows to hotlist, part backwash main filter screen, arrange to return pipe together with outlet under the warp of the mechanical admixture in the main filter screen working chamber, thereby realize backwash automatic pollution discharge purpose; Close ball valve, will revolve the core homing, filter returns to first kind of duty again.

The utility model is furnished with the I type and revolves core and II type and revolve core and revolve core for two kinds, can exchange, can select according to actual needs wherein a kind of, to realize different backwash effects; Its compact conformation is skillfully constructed, and is easy to operate, safety and sanitation, and reliable operation is a kind of desirable family's hotlist automatic pollution discharge filter.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
