Through the unique valve seats capable of relieving pressure, the utility model ensures that valve can be fully sealed under high-pressure, low-pressure and vacuum states, improves the safety and the sealing performance of the whole ball valve, and has the advantages of little pressure loss, labor-saving operation, convenient repair, reliable action and the like.
Description
Technical field
The utility model relates to a kind of valve component, particularly a kind of floating ball valve.
Background technique
Ball valve mainly is applicable to industrial systems such as oil, letter shoot line and power station, chemical industry, metallurgy, it has anti-normal temperature, anticorrosive, applied widely, operation advantage such as nimble, therefore use very extensive, and the circulation of existing floating ball valve upstream and downstream fluid is to rotate the through hole that makes on the spheroid medial axis by spheroid in valve body to communicate with the upstream and downstream mouth of pipe and realize, therefore there are easy to leak, the not defective of easy care.
The model utility content
The utility model is by improving existing floating ball valve, thereby make valve at height, can seal fully under low pressure and the vacuum state, and be convenient to dismounting, the utility model provides a kind of floating ball valve, comprise valve body, valve gap, spheroid, valve rod and handle, described valve rod is arranged in the valve body, stem bottom links to each other with spheroid, be provided with valve seat in the described valve body, described spheroid is arranged between 2 valve seats, described valve seat respectively with the contacting of valve body and valve gap, described valve body is connected by screw bolt and nut with valve gap, is provided with O type circle and Graphite pad between described valve body and the valve gap, described valve body is provided with limiting board, described handle is arranged on valve stem tip, is provided with gland between described valve rod upper end and the handle, dish spring and locking plate are provided with spring and bead in the described valve rod.
As another kind of improvement the of the present utility model, described spring and bead are respectively antistatic spring and antistatic bead, for antistatic the utility model is being provided with the antistatic spring to prevent friction-produced static between spheroid and the valve seat between valve rod and the valve body.
But the utility model is by adopting unique valve seat of pressure release, thereby guarantee that valve can seal fully under high and low pressure and vacuum state, improved the Security and the sealing of whole ball valve, and it is few to have the pressure loss, rapid operation, easy to maintenance, advantages such as reliable in action.
