Problems solved by technology

Due to the soft material of the nylon seat, it is easy to get impurities on the surface, resulting in a poor seal between the steel ball and the nylon seat, resulting in internal leakage, which affects the reliability of the multi-way valve.

Abstract

The invention discloses an integral multiway valve with integral hydraulic locks and a fouling resistant plug-in mounting overflow valve. The integral multiway valve comprises an oil inlet valve block, a plurality of working valve blocks and an oil returning valve block. The oil inlet valve block, the working valve blocks and the oil returning valve block are of an integral structure. The oil inlet valve block is provided with an oil inlet P, and the oil returning valve block is provided with an oil returning port T. Each working valve block is provided with a working oil port, wherein a valve rod is inserted into the working oil port. Each working valve block is internally provided with one integral hydraulic lock, one valve rod, one double-lock hydraulic control push rod and a back plug. Each integral hydraulic lock comprises a steel lock valve base, a lock valve element, a lock valve sleeve and a reset spring. The oil inlet valve block is internally provided with the plug-in mounting overflow valve. The integral multiway valve with the integral hydraulic locks and the fouling resistant plug-in mounting overflow valve has the advantages that the risk of oil leakage can be reduced, internal leakage is avoided, working reliability of the valve is improved, the machining technology is simplified and machining cost is reduced.

Description

technical field [0001] The invention relates to a multi-way valve, in particular to an integral multi-way valve provided with an integral hydraulic lock and a pollution-resistant plug-in overflow valve. Background technique [0002] Harvesting is a highly seasonal, labor-intensive and labor-intensive link in the agricultural production process. In production practice, harvesting is often closely linked with the sowing of the next crop. Farmers often use "rushing to harvest and rush to plant" as a metaphor for the urgency of work, and associate it with a bumper harvest. With the development of the national economy, especially the rural economy and agricultural productivity, farmers are increasingly calling for the mechanization of rice and wheat harvesting, and the role and significance of harvesting mechanization are being recognized by more and more people. In the harvesting machinery industry, hydraulic technology has been more and more widely used, and the application p...
