Abstract
The utility model discloses an integrated manual overflow reversing valve. The integrated manual overflow reversing valve comprises a valve body and a slide valve in an inner cavity of the valve body, wherein the both ends of the slide valve are respectively connected with a spring location mechanism and an operation rod; a working cavity and an oil return channel are arranged in the valve body; an overflow valve mounting hole is also formed in the valve body; and an overflow valve is mounted in the overflow valve mounting hole which is communicated with the working cavity and the oil return channel. According to the utility model, the overflow valve and a reversing valve are designed to have an integrated structure so as to provides oil channel overload protection during the use of the reversing valve. In addition, the integrated manual overflow reversing valve provided by the utility model has the advantages of small size, low cost, reliable performance, and greatly widened application range.
Description
Technical field
The utility model relates to the manually operated valve field, is specifically related to integral manual overflow selector valve.
Background technique
Hand-operated direction valve is the controlling component in the pipeline fluid transporting system, and by operating handle tractive guiding valve, the guiding valve displacement changes path section and media flow direction.In the hand-operated direction valve using process; often On The Problem Of Overpressure can appear; in order to protect the work safety of oil circuit; need to establish a relief valve oil circuit is carried out overload protection; mostly existing hand-operated direction valve is an external relief valve, need to set up auxiliary oil pipe and other auxiliary valve, and auxiliary oil pipe and auxiliary valve not only can increase the user cost of hand-operated direction valve; and volume is large, affects the complete machine layout of selector valve.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of integral manual overflow selector valve, relief valve and selector valve integrative-structure, and volume is little, cost is low, reliable performance, and application area significantly promotes.
The utility model is achieved through the following technical solutions:
Integral manual overflow selector valve, comprise the guiding valve in valve body and the valve body internal valve cavity, the guiding valve two ends are linking springs positioning means and operating stem respectively, be provided with active chamber and oil return circuit in the valve body, also be provided with the relief valve mounting hole on the described valve body, relief valve is installed wherein, and described relief valve mounting hole communicates with active chamber and oil return circuit.
The utility model compared with prior art has following obvious advantage:
The utility model is designed to integrative-structure owing to being provided with the relief valve mounting hole at hand-operated direction valve with relief valve and selector valve, provide the oil circuit overload protection in the selector valve using process, and volume is little, cost is low, and reliable performance just significantly promotes with scope.
