Description

A kind of Parallel gate valve Parallel slide valve
Technical field
The utility model relates to valve field, particularly a kind of Parallel gate valve Parallel slide valve.
Background technique
Gate valve is an open-shut device flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, and when gate valve is closed, sealing surface can only rely on pressure medium to seal, and namely only relies on medium
The sealing surface of flashboard is pressed to the valve seat of opposite side to ensure the sealing of sealing surface by pressure, selfsealings that Here it is.Major part gate valve adopts forced seal, namely during valve closing, external force be relied on by force flashboard to be pressed to valve seat, to ensure sealingthe sealing in face.
Gate valve have flow resistance little, when opening and closing more laborsaving, medium can to two any directions flowings, be easy to advantages such as installing, body is simple, good manufacturability, structure length are less, this also makes gate valve usage range very wide, but most gate valve is intake at the easy top from gate valve, valve seat is easily by erosion, and the resistance of gate valve is comparatively large, the easy problem such as leakage.
Model utility content
For the deficiency that above-mentioned gate valve exists, technical purpose of the present utility model be to provide a kind of sealability better, valve stem top is sealed, fed sheet of a media resistance is less, have hard, soft valve seat concurrently, the Parallel gate valve Parallel slide valve of the longer service life of valve seat, this gate valve can make pipe-line system more reliable.
The utility model is achieved through the following technical solutions:
A kind of Parallel gate valve Parallel slide valve, described Parallel gate valve Parallel slide valve comprises: valve body, valve seat, valve plate, valve rod, valve seat and valve plate is provided with in described valve body, the bottom of described valve rod is arranged on the top of valve plate, described valve plate is provided with pod apertures, the top of described valve body is provided with valve rod frame, described valve rod frame is divided into upper valve rod frame and lower valve rod frame, described valve rod is arranged in upper valve rod frame and lower valve rod frame, sylphon seal is provided with between described lower valve rod frame and valve rod, be provided with Stem Mut between described upper valve rod frame and valve rod, the top of described valve rod is provided with handwheel.
