Abstract
The utility model discloses a spherical fine-tuning type non-return valve. The spherical fine-tuning type non-return valve comprises a barrel-type valve body; an outer wall of the valve body bulges outwards; the lower end of the valve body is a water inlet end; the upper end of the valve body is a water outlet end; a spherical cover is fixedly arranged in the barrel-type valve body; a sealed sphere is arranged at the lower end of the spherical cover; a cone is arranged at the lower end of the spherical cover; the sealed sphere is buckled in the cone; a water-passing groove is arranged on an inner wall at one side of the cone; a stopping block is arranged below the sealed sphere; an adjustment threaded rod is screwed on the stopping block; the top end of the adjustment threaded rod supports the bottom end of the sealed sphere; a cavity is arranged in the sealed sphere; a balancing rod is arranged in the cavity; and positioning balls are sleeved on two ends of the balancing rod in a sliding manner. The spherical fine-tuning type non-return valve is reasonable in structural design and good in water-seal effect and can be widely applied to high-rise buildings and water supply and drainage pipelines.
Description
Technical field
The utility model relates to safety check, specifically belongs to spherical fine turning safety check.
Background technique
The open-shut device of safety check leans on media flow and strength to open voluntarily or close, with the valve that prevents the medium refluence on safety check.Safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.The ball-type wastewater stopping valve: valve body adopts the full tunnel structure, has the advantage that flow is big, resistance is little.Adopt ball to do flap, be applicable to high viscosity, the industry and the domestic sewage pipe network of suspended matter are arranged.
The model utility content
The purpose of the utility model provides a kind of spherical fine turning safety check, reasonable in design, and stagnant water effect is good, and the openings of sizes of crossing water groove is adjustable, has the function of fine setting simultaneously, can be widely used in tall building, the water supply and sewerage pipeline.
Spherical fine turning safety check includes the valve body of tubular, and valve outer wall is outwards heaved; The lower end of valve body is that feed-water end, upper end are the waterexit end, and the cylindrical shell internal fixation has ball cover, and the lower end of ball cover is placed with ball sealer; The lower end of described ball cover has cone, and engaging has ball sealer in the cone, and a side inwall of cone was provided with water groove; The ball sealer below is provided with block, is combined with adjusting screw rod on the block, and the top jacking of adjusting screw rod is in the bottom of ball sealer; Have cavity in the ball sealer, be provided with balancing pole in the cavity, place kick is equipped with at the two ends of balancing pole flip sleeve respectively.
The top of described ball sealer is provided with support, and the bottom of support has pallet.
During the utility model turn on pump, liquid gets into valve from inlet channel, opens sealing sphere liquid through a plurality of through flow holes on the panel and just flows to outlet through a ball cover sidewall through hole entering valve body annular space, and this process is an opening process.During termination of pumping, liquid gets into valve body from outlet, and ball sealer will be closed on the face of ball cover under the effect of hydraulic pressure, thereby by the snout cavity that flows to, this process is the termination of pumping process, and ball sealer has improved the stability of ball sealer to crossing the tank lopsidedness.
The utility model reasonable in design, the openings of sizes of crossing water groove is adjustable, has the function of fine setting simultaneously, and stagnant water effect is good, can be widely used in tall building, the water supply and sewerage pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model.
