Abstract
The utility model relates to a valve body of the multiway hydraulic valve, and the valve body is an integral casting. A valve cavity 1, a valve cavity 2, a valve cavity 3, and a valve cavity 4 are communicated with each other through an oil way 1; a valve cavity 5 and a valve cavity 6 are communicated with each other through an oil way 2. The valve body is cast by precision casting, since the whole valve body has an integral structure, the defects, such as leakage, and the like, brought by multichip assembly of the traditional valve body are avoided. Since the utility model has rational and compact structure, and small mechanical workout volume, the work period is reduced, and the using of the sealing pieces is reduced, the product quality is more stable with better performance, and the utility model can be widely applied to the hydraulic valve used in the car and the crane, thus having great practical and popularizing value.
Description
Technical field
The utility model relates to the valve body of a kind of multi-path hydraulic valve in the hydraulic system.
Background technique
Relevant by retrieval patent documentation, the present valve body that does not retrieve the multi-path hydraulic valve identical as yet with the utility model structure.The valve body of existing multi-path hydraulic valve, because complex structure, a plurality of lamellar bodies are generally all made valve body in processing for convenience, assemble with bolt again; Be prone to phenomenons such as seepage at junction plane because it forms the back, cause stability to descend, thus be necessary that in addition this advances to improve to existing valve body, so that satisfy actual needs better.
Summary of the invention
The purpose of this utility model is that a kind of concrete overall structure, the valve body of a kind of multi-path hydraulic valve rational in infrastructure will be provided.
Technical characteristics of the present utility model is: on the basis of considering compact structure, and the valve body of described multi-path hydraulic valve, the foundry goods of the as a whole structure of its valve body, described valve pocket I, valve pocket II, valve pocket III, valve pocket IV communicate by oil duct I; Connect by oil duct II between described valve pocket V, the valve pocket VI.The valve body of described valve body for adopting precision casting to cast.
Valve body is designed to overall structure, its objective is that being prone to the seepage phenomenon for fear of the traditional product combinating face designs, and forms naturally when the oil duct in the inner chamber adopts casting, has reduced amount of finish.
The utility model has the advantages that: because whole valve body is designed to an integral body, thereby the defectives such as seepage of having avoided traditional multichannel valve body multi-disc assembling to bring, because compact structure, rationally, machining amount is little, manufacture cycle is shortened, reduced the use of Sealing simultaneously, made quality of product more stable, performance is better, so on the hydrovalve that can be widely used in using on automobile, the hoist, so very big practical and popularizing value is arranged.
Description of drawings
Further describe the utility model below with reference to accompanying drawing:
Accompanying drawing 1 is the plan view of the valve body of a kind of multi-path hydraulic valve of the utility model;
Accompanying drawing 2 is plan views of a kind of valve body of multi-path hydraulic valve;
Accompanying drawing 3 is the sectional views along the A-A section of accompanying drawing 2;
Accompanying drawing 4 is stereograms of a kind of valve body of multi-path hydraulic valve.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, the valve body of a kind of multi-path hydraulic valve of the utility model, the integrally-built foundry goods of its valve body for adopting precision casting to cast, described valve pocket I1, valve pocket II2, valve pocket III3, valve pocket IV4 communicate by oil duct I5; Connect by oil duct II8 between valve pocket V6, the valve pocket VI7.
Claims (2)
1. the valve body of a multi-path hydraulic valve is characterized in that: the foundry goods of the as a whole structure of valve body, and described valve pocket I (1), valve pocket II (2), valve pocket III (3), valve pocket IV (4) communicate by oil duct I (5); Connect by oil duct II (8) between described valve pocket V (6), the valve pocket VI (7).
2. the valve body of a kind of multi-path hydraulic valve according to claim 1 is characterized in that: the valve body of described valve body for adopting precision casting to cast.
