Abstract
The invention discloses an overflow valve of a filtering device. The overflow valve comprises an overflow valve body and a one-way valve. The overflow valve body and the one-way valve are arranged inside an overflow valve case. Two ends of an oil inlet hole inside the overflow valve case are communicated with an oil outlet of an oil pump and an upper cavity of the one-way valve respectively. An oil outlet hole of the right side inside the overflow valve case is respectively communicated with the lower cavity of the one-way valve and the filtering device. Two ends of the other oil outlet hole inside the overflow valve case are communicated with the overflow valve body and a gearbox respectively. The overflow valve has the advantages of being small in occupied space and lowering packaging and transporting cost.
Description
Technical field:
The present invention relates to the relief valve of a kind of filtering technique, particularly a kind of filter.
Background technique:
Gear case oil in the wind power equipment needs to filter in cyclic process, in this circulatory system, in order to prevent because plugged filter when serious, fluid can not be got back to and cause gear-box not have oil in the gear-box, oil circuit between filter and gear-box arranges relief valve, the relief valve of She Zhiing is when filter stops up when serious like this, if do not quit work immediately, the oil that comes out from oil pump can not directly be entered through relief valve filter core is damaged.Existing relief valve is arranged on the outside of filter simultaneously, the bulk of filter system and motor and oil pump is increased, influence packing and transportation.
Summary of the invention:
The object of the invention provides a kind of relief valve that prevents a kind of filter of filter core damage and take up room little reduction packing and cost of transportation.
The technological scheme that realizes the object of the invention is, a kind of relief valve of filter, comprise relief valve and one-way valve, it is characterized in that: in the overflow valve casing, be provided with relief valve and one-way valve, the oil outlet of the two-port difference oil pump of the oil inlet hole in the described overflow valve casing and the epicoele of described one-way valve are communicated with, the oil outlet on right side is communicated with cavity of resorption and the filter of described one-way valve respectively in the described overflow valve casing, and the two-port of another oil outlet in the described overflow valve casing is communicated with described relief valve and gear-box respectively.
The present invention has the advantage little and reduction packing and cost of transportation that takes up room compared with the prior art.
Description of drawings:
Fig. 1 is plan view of the present invention; Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment:
The technological scheme that the present invention solves the problems of the technologies described above is, move on to oil pump and filter between by filter right side, original place relief valve and contiguous block herein assembles one, concrete structure is, in overflow valve casing 4, be provided with relief valve 5 and one-way valve 6, the two-port of the oil inlet hole in the described overflow valve casing is communicated with the oil outlet of oil pump 3 and the epicoele 8 of described one-way valve respectively, the oil outlet 9 on right side is communicated with cavity of resorption 10 and the filter 1 of described one-way valve respectively in the described overflow valve casing, and the two-port of another oil outlet 7 in the described overflow valve casing is communicated with described relief valve and gear-box respectively.
Working principle of the present invention is, under the filter normal condition, one-way valve is in open mode, relief valve then is in closed condition, the oil pump that driven by motor 2 this moment is extracted the oil in the gear-box out in the overflow valve casing oil inlet hole to the cavity of resorption of one-way valve, oil outlet in the overflow valve casing enters filter, gets back in the gear-box after filtering.When filter uses the regular period and stops up when serious, because oil pressure raises when reaching setting value, relief valve is opened, and fluid is directly got back in the gear-box through relief valve and another oil outlet 7, thereby the generation of having avoided oil pump to find time.
