Abstract
The utility model belongs to a valve, in particular to a check filter combined valve which makes a piston (stop) valve and a filter into integration. The utility model mainly comprises a piston (stop) valve part formed by a valve body, a valve cap, a valve rod and a piston. The utility model is characterized in that a lower filter cavity is arranged on a same prolonged axis of a stop cavity on the valve body, the inlet of which is communicated with the stop valve, while the outlet of the valve body is communicated with the lower filter cavity of valve body with a cylinder filter screen. And the axis of the stop cavity in the valve body and the filter cavity part and the connecting axis of the inlet of valve body and the outlet pipeline form an included angle. The utility model has the beneficial effects that a valve has two functions of stop and filter, thereby reducing the cost of valve, reducing the using space and installing time and prolonging the service life of valve, in particular improving the repairing efficiency when applied in liquid (gas) pipeline with impurity.
Description
Technical field
The utility model belongs to valve field, relate in particular to a kind of with plunger (ending) valve and filter make one by filtering combination brake switch and proporting.
Background technique
Plunger valve in the known technology, stop valve occasion different with the filtration device structure function and that use is also different, acts on singlely, and all is independent use.Especially at liquid (gas) body plunger valve and the stop valve that uses in the pipeline of impurity arranged, owing to impurity is arranged through regular meeting's blocking pipeline and wearing and tearing valve in the fluid, the working life of causing valve is short and often overhaul pipeline or change valve.
The model utility content
Technical problem to be solved in the utility model is to overcome above-mentioned plunger (ending) valve at liquid (gas) body the defective of using in the pipeline of impurity to be arranged, and provide an a kind of valve have unidirectional by and filter double effects by filtering combination brake switch and proporting.
The technological scheme that the utility model adopted is: a kind of by filtering combination brake switch and proporting, the plunger that it mainly is made of valve body, valve gap, valve rod and plunger (ending) valve portion, it is characterized in that going up on the same prolongation axis in chamber in the described valve body filtering cavity is set down, the import of its valve body be communicated with by the chamber, and the outlet of valve body is communicated with filtering cavity under the valve body that the tubular filter screen is housed.And in the valve body by the axis and the valve body import of chamber and filtering cavity part with the export pipeline coupling shaft is linear has angle.
The beneficial effects of the utility model are: have the structure and the effect of ending and filtering owing to designed on a valve, promptly reduced the manufacture cost of valve, reduced usage space and installation work-hour, prolonged the working life of valve.Improve overhaul efficiency when particularly in the liquid of impurity (gas) pipeline is arranged, using.
