Abstract
The utility model relates to the technical field of air conditioners, and discloses a hydraulic press device of an improved structure. The hydraulic press device comprises an inlet end, a first airtight end, a second airtight end and an outlet end. The inlet end and the outlet end are horizontally arranged and partitioned by a baffle. The first airtight end and the second airtight end are arranged in parallel and are perpendicular to the inlet end and the outlet end. The first airtight end is provided with a first hydraulic valve. The second airtight end is provided with a second hydraulic valve. The first hydraulic valve comprises a first airtight valve, a second airtight valve and a third airtight valve, wherein the first airtight valve, the second airtight valve and the third airtight valve can be independently switched on and off, and the ratio of the airtight effect of the first airtight valve to the airtight effect of the second airtight valve to the airtight effect of the third airtight valve is 1:2:4. The second hydraulic valve comprises a first auxiliary sealing valve, a second auxiliary sealing valve and a third auxiliary sealing valve which can be independently switched on and off. The hydraulic press device is simple in structure and novel in design, the inverted T-type loop design is adopted, the effective road segment is longer, the air pressure of the first airtight end and the second airtight end can be more precisely controlled, and therefore the control precision of the hydraulic press device is higher.
Description
Technical field
The utility model belongs to hydraulic pressure device technical field, relates in particular to a kind of structure improved hydraulic pressure device device.
Background technique
Current making rapid progress along with science and technology, the sci-tech products such as especially weaving, papermaking, metering, quality inspection, military affairs, space flight, aviation, electronics, biomedicine are produced, process, are detected and all be unable to do without constant-temperature constant-humidity air-conditioner, humidity control apparatus is as the important component part of constant-temperature constant-humidity air-conditioner, and its humidity control is generally divided into several as follows:
Extra fine grade relative moisture ± 2%;
Fine grade relative moisture ± 3%;
