The invention discloses a stop valve for a single energy accumulator. The stop valve comprises a first valve body, a connecting section and a second valve body. The first valve body is connected with a connecting pipe, the second valve body is connected with a connector, and the connecting pipe, the first valve body, the connecting section, the second valve body and the connector are communicated with one another. A first cone valve is arranged in the first valve body, a second cone valve is arranged in the second valve body, an oil returning port is formed in the second valve body, and the oil returning port and the connector are located on the two sides of the contact position of the second valve body and a second conical face respectively. Sealing rings are arranged between the first cone valve and a first valve plug and between the second cone valve and a second valve plug. The stop valve has the advantages of being simple in integral structure, convenient to install and maintain, free of occupying the space, light, flexible, safe and reliable.
Description
technical field [0001] The invention relates to a valve, in particular to a shut-off valve for a single accumulator. Background technique [0002] The existing cut-off valves for single accumulators are all ball valves, with complex structure, large volume, heavy weight, and inconvenient installation and maintenance. Contents of the invention [0003] The object of the present invention is to provide a stop valve for single accumulator with simple structure, small size, no space occupation, light weight and flexible application, so as to overcome the shortcomings of the prior art. [0004] The cut-off valve for single accumulator of the present invention comprises a first valve body and a second valve body, there is a connecting section between the first valve body and the second valve body, and there is a valve connected to the pressure oil on the first valve body. The connecting pipe has an interface connected to the accumulator on the second valve body, and the connect...
