High pressure manual Globe Valve
technical field
[0001] the utility model relates to a valve which is mainly applied to the maintenance of the hydraulic system of large isostatic press,
The utility model relates to a manual Globe Valve applied to the high-pressure pipeline of the working cylinder of a large isostatic press.
Background technology
[0002] with the continuous expansion of the application field of isostatic pressing technology, there is an increasing demand for large pressed parts
Hydrostatic press also increased. However, during the maintenance of the hydraulic system of the large isostatic press, the existing large isostatic press is in the high-pressure pipe
This functional valve is not set on the road, often because the residual hydraulic oil in the working cylinder can not be completely drained, resulting in a large number of problems
The oil flows out of the working cylinder, which not only causes the oil loss and pollutes the environment, but also brings a lot of inconvenience to the maintenance of high-pressure pipeline.
Content of utility model
[0003] the purpose of the utility model is to provide a simple, convenient, easy to operate, safe and reliable high-pressure manual cut-off valve
Valve to overcome the defects of oil loss, environmental pollution and inconvenient maintenance during high-pressure pipeline maintenance.
[0004] the technical scheme adopted by the utility model to solve the technical problem is: a high-pressure manual Globe Valve, comprising a
A valve core connected with a hand wheel and a valve body assembled with the valve core through a flange are characterized in that the ring groove at the end of the valve core
A sealing element group composed of a sealing ring, an O-ring and a retaining ring bearing ultra-high pressure is installed, and a conical hard seal is arranged between the valve core and the valve body
A safety transmitting device for detecting the position of the valve core is arranged on the valve body
[0005] the utility model has the following beneficial effects:
[0006] simple structure, easy operation, safety and reliability. The utility model adopts that the valve core is provided with a sealing ring which can bear ultra-high pressure
The sealing element group and the conical hard seal between the valve core and the valve body can not only bear the role of ultra-high pressure seal, but also prevent
Stop the outflow of high-pressure hydraulic oil in the working cylinder. It not only provides the convenience of maintenance and operation on the high-pressure pipeline, but also
It ensures the safety and reliability of tight sealing in maintenance operation. It overcomes the large oil loss and environmental pollution in traditional maintenance
Serious and inconvenient maintenance defects.
[0007] on the high-pressure pipeline of the working cylinder of the large isostatic press, the normally open super open valve with the valve core fully open is added
High pressure manual Globe Valve ensures the safety and smoothness of the pipeline. A grounding device which can detect the position of the valve core is arranged on the valve body
The utility model avoids the disadvantage that the ultra-high pressure manual Globe Valve is not opened when the press works. When the proximity switch sends a message, the ultra-high voltage is manual
The Globe Valve is open.
