Abstract
The invention relates to the technical field of valves, in particular to a novel ball valve capable of being maintained without a production halt. The novel ball valve capable of being maintained without the production halt is characterized by comprising a valve jacking block, a bayonet, a ball, a valve seat, a seal, a valve rod, a sealing spacer, a soft seat, an upper liquid circuit, a liquid opening, a liquid circuit, a long liquid tube, a bottom oil seal, a valve body and a pipeline. According to the novel ball valve capable of being maintained without the production halt, the liquid opening is formed in the valve body; the liquid circuit is arranged at the lower end of the liquid opening; the long liquid tube is arranged at the lower end of the liquid circuit; the upper liquid circuit is arranged on the long liquid tube; the soft seat is arranged at the upper end of the upper liquid circuit; the ball is arranged at the upper end of the soft seat; the liquid opening is formed in the valve body; the liquid circuit is chiseled at the lower end of the liquid opening; the liquid circuit is connected with the liquid opening; the long liquid tube is chiseled at the lower end of the liquid circuit; the long liquid tube is connected with the liquid circuit; meanwhile, the upper liquid circuit is chiseled and connected with the long liquid tube; the soft seat is arranged at the upper end of the upper liquid circuit and inlaid into a groove of the valve body; and the soft seat inlaid in the groove of the valve body can make contact with the ball to form the valve seal and also can achieve the function of the valve seat.
