Embodiment Construction
[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.
[0027] Please refer to the figure. The split pilot valve of the present invention includes a first valve body 1 and a second valve body 2 arranged symmetrically with the first valve body 1. The connection between the first valve body 1 and the second valve body 2 is through a connecting piece. 3 are connected together to form the whole valve body. Wherein, in this embodiment, the connecting member 3 is a bolt.
[0028] The outer surface of the first valve body 1 is pro...

The invention discloses a split pilot valve. The split pilot valve comprises a first valve body and a second valve body. The first valve body is provided with two oil path holes which communicate with first oil channels. First rectangular holes are formed in the inner side face of the first valve body. The sides, close to the two upper rectangular holes, of the lower rectangular holes are provided with two arc-shaped grooves, and the radius of the first arc-shaped groove is greater than that of the second arc-shaped groove. Second oil channels are formed in the second valve body. Second rectangular holes are formed in the inner side face of the second valve body. The second rectangular holes and the first rectangular holes are consistent in shape and position. When the first valve body and second valve body are connected together through connecting parts to form a whole valve body, the second rectangular holes and the first rectangular holes are connected together in a butt-joint mode, so that the first oil channels communicate with the second oil channels. The split pilot valve is universal, low in machining difficulty and high in machining precision.
Description
technical field [0001] The invention relates to a split pilot valve. Background technique [0002] The oil-guiding pilot valve below the hand-operated pilot valve on the existing excavator is integrally formed, which makes it very difficult to process the oil circuit in the pilot valve and the machining accuracy is not high, which often cannot meet the requirements. At the same time, the handle and the pilot valve are all integrally formed, which will cause the pilot valve not to be universal and unable to achieve mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a split pilot valve with versatility, low processing difficulty and high processing precision. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a split pilot valve, including a first valve body and a second valve body symmetrically arranged with the first valve body, the first va...
