Abstract
The utility model discloses a kind of loader multiple directional control valve dustproof construction, belong to loader hydraulic system dust guard field, be mainly used in loader multiple directional control valve dust-proof, it comprises end cap, described end cap is provided with dust-proof cover, described dust-proof cover is the telescopic wave structure of hollow, and is connected with end cap by connection set.In view of technique scheme, the utility model overcomes multi-way reversing valve member and hydraulic system is high because dust impurities pollutes the rate of fault caused, the problem that working life is short.
Description
Technical field
The utility model belongs to loader hydraulic system dust guard field, specifically, particularly relates to a kind of loader multiple directional control valve dustproof construction.
Background technique
Loader is as machinery important in engineering machinery; its working environment is comparatively severe; the pollutants such as dust are more, bring baptism to the high cleanliness of hydraulic system and critical component, therefore need in using process to carry out proofing dust and protecting to hydraulic system and critical component.And in actual use, multiple directional control valve needs to move back and forth, the two ends of multiple directional control valve lack the dust-proof protective gear waiting pollutant, and the impurity such as particle very easily enter multiple directional control valve inside, cause the fault of hydraulic system.
Summary of the invention
The utility model discloses a kind of loader multiple directional control valve dustproof construction, it can overcome multi-way reversing valve member and hydraulic system is high because dust impurities pollutes the rate of fault caused, the problem that working life is short.
The utility model is achieved through the following technical solutions:
Loader multiple directional control valve dustproof construction described in the utility model, comprise end cap, described end cap is provided with dust-proof cover, and described dust-proof cover is the telescopic wave structure of hollow, and is connected with end cap by connection set.
On the basis of technique scheme, the dust-proof cover in the utility model can preferably adopt extension type sealed colloid to make further, and described connection set is larynx hoop.
Compared with prior art, the utility model has following beneficial effect: the utility model can overcome conventional load machine multiple directional control valve and carry out with external environment the problem that gas exchanges sucks particle foreign material in operation, make multiple directional control valve can have higher dust-proof effect, ensure the hydraulic system of loader and the working life of related keyword structure, reduce rate of fault.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is rigging position schematic diagram of the present utility model.
In figure: 1, end cap; 2, connection set; 3, dust-proof cover.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of loader multiple directional control valve dustproof construction, comprises end cap 1, and described end cap 1 is provided with dust-proof cover 3, and described dust-proof cover 3 is the telescopic wave structure of hollow, and is connected with end cap 1 by connection set 2; Described dust-proof cover 3 adopts extension type sealed colloid to make, and described connection set 2 is larynx hoop.
In actual use, the valve rod to-and-fro motion due to multiple directional control valve makes the space of end cap 1 inside that the change of volume occur to the utility model, and then the air exchange of formation and external environment condition, may cause sucking the particle foreign material such as the dust in air.The utility model end cap 1 will install enclosed dust-proof cover 3 additional; block multiple directional control valve and external environment carries out air exchange; because dust-proof cover 3 is the wave structure of extension type; can change accordingly when end cap 1 interior space volume changes; thus ensure that the normal commutation function of multiple directional control valve; and the intrusion of environmental contaminants also stopped by enclosed spatial structure; the turbidity test of hydraulic environment are improved further, improves the reliability of hydraulic system and critical component.
Claims (2)
