Estimating the term…
The gate valve has a housing hermetically joined with pipelines and a closing member which is translationally traversable in between the sealing elements of the housing. A bottom end of the closing member having a bevelled edge made so that at the instance when the pipelines get intercommunicated, the passageway is established in between the abovesaid bevelled edge, the housing and the sealing elements, said passageway growing narrow towards the direction of the flow of liquid. The above feature makes it possible to rule out the onset of conditions fraught with cavitation under the closing member and bring the cavitation outside the closing member, thereby adding to the service life of the gate valve.
A gate valve comprising, a valve housing defining a flow path therethrough having an inlet and an outlet to allow flow of a liquid therebetween, a gate valve operable to close and open the valve and disposed to extend across said flow path substantially normal to the flow of liquid therethrough, said gate valve having a tapered lower edge extending across a lower portion of a major side face of the gate, said gate decreasing in cross section toward said lower edge and in a direction toward the periphery of said face in a direction toward the direction of flow of said liquid, a projection extending downwardly from said lower edge, and said projection having a width substantially less than the width of said gate across said flow path.
A gate valve comprising, a valve housing defining a flow path for flowing a liquid therethrough, a movable gate valve in said valve housing operable to a position closing said flow path and to a position in which said valve is open and liquid can flow through said flow path;
