Abstract
The utility model discloses a pressure-adjustable ball check valve which comprises a cylindrical valve body, wherein the outer wall of the valve body bulges outwards; the lower end of the valve body is a water inlet end, and the upper end is a water outlet end; a ball cover is fixed in the cylinder; a seal ball is arranged at the lower end of the ball cover; the upper end of the seal ball is fixed with a T-shaped support; a support rod of the T-shaped support is provided with an external thread; the support rod is provided with an adjusting nut through a threaded manner; a spring is sleeved outside the support rod; the upper end of the spring is pressed on the adjusting nut, and the lower end of the spring is pressed on the upper surface of the seal ball; and a cambered water flow gap is formed between one side of the seal ball and the inner wall of the ball cover. The pressure-adjustable ball check valve has a reasonable structural design and a good water seal effect; the seal ball can be elastically pressed by the spring; the adjusting nut can be rotated, so that the preliminary pressure of the spring can be controlled; and a rubber anti-wear layer can further ensure the sealing property. Thus, the pressure-adjustable ball check valve can be widely used for high-rise buildings and water supply/drainage pipelines.
Description
Technical field
The utility model relates to safety check, but specifically belongs to the pressure regulating type ball check valve.
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
But the purpose of the utility model provides a kind of pressure regulating type ball check valve, utilizes spring to suppress ball sealer, but while turn-knob adjusting nut; Thereby the precompression of control spring; Reasonable in design, stagnant water effect is good, can be widely used in tall building, the water supply and sewerage pipeline.
The technological scheme of the utility model is following:
But the pressure regulating type ball check valve 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 upper end of ball sealer is fixed with T shape support, has outside thread on the pole of T shape support, has screwed togather adjusting nut on the pole; Pole is set with spring outward; The upper end of spring is pressed on adjusting nut, and the lower end of spring is pressed on the upper surface of ball sealer, and the inwall of ball sealer one side and ball cover has the water space excessively of arc.
The below of described ball sealer is provided with block.
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.
The utility model utilizes spring to suppress ball sealer, but while turn-knob adjusting nut, thus the precompression of control spring; While rubber wear-resisting layer is sealability further; Reasonable in design, 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.
Embodiment
Referring to accompanying drawing, but the pressure regulating type ball check valve includes the valve body 1 of tubular; Valve body 1 outer wall is outwards heaved, and the lower end of valve body 1 is that feed-water end 2, upper end are waterexit end 3, and cylindrical shell 1 internal fixation has ball cover 4; The lower end of ball cover 4 is placed with ball sealer 5, and the upper end of ball sealer 5 is fixed with T shape support 6, has outside thread on the pole 7 of T shape support 6; Screwed togather adjusting nut 8 on the pole, be set with spring 9 outside the pole 7, the upper end of spring 9 is pressed on adjusting nut; The lower end of spring is pressed on the upper surface of ball sealer 5, and the inwall of ball sealer one side and ball cover has the water space 10 excessively of arc, and the below of ball sealer is provided with block 11.
