Abstract

A multiple directional control valve spring shield comprises a base and a barrel, wherein the base and the barrel are formed in an integrated mode, a spring installation hole and an overflow valve hole are formed in the multiple directional control valve spring shield, internal threads are formed in the overflow valve hole, and four corners of the base are provided with fixing bolt holes. The multiple directional control valve spring shield has the advantages that the structure is simple, forming convenience is achieved, the size is small, material consumption is low, one reversing valve needs to be provided with six spring shields in the past, now one reversing valve only needs to be provided with the two multiple directional control valve spring shields, production cost is lowered, and economical benefits are improved.

Description

The multiple directional control valve spring shield
Technical field
The utility model relates to a kind of hoist component, specifically a kind of multiple directional control valve spring shield.
Background technique
At present, general mechanic factory workers production hoist selector valve spring shield is all generally the cast iron manufacture, the moulding by casting trouble, and materials are many, and volume is large, needs to use 6 spring shields on a selector valve, and cost is high.
The model utility content
The deficiency existed for above-mentioned similar technical problem, the purpose of this utility model is to provide a kind of simple in structure, multiple directional control valve spring shield that volume is little.
The technical solution of the utility model is: the multiple directional control valve spring shield, comprise base, cylindrical shell, it is characterized in that: base and cylindrical shell are one-body molded, and inside has spring mounting hole and overflow valve opening, overflow valve opening inside is processed with internal thread, and four angles of base are processed with fixing screw hole.
The utility model has the advantages that: this product structure is simple, convenient formation, volume is little, materials are few, to need to use 6 spring shields on last selector valve, uses now two of a need on selector valve of this product to get final product, reduce cost of production, improved economic benefit.
