Detailed Description
The embodiment discloses an r-shaped check valve, which comprises an r-shaped tee joint 1 and a limiting ball 3 which is arranged in the r-shaped tee joint 1 in a limiting way;
the r-shaped tee joint 1 comprises a vertical conveying pipe 12 and a lateral liquid outlet pipe 11 communicated with the vertical conveying pipe 12 in an r shape; wherein the length of the lateral liquid outlet pipe 11 is smaller than the radius of the limiting ball 3 so as to be convenient for the lateral liquid outlet pipe to automatically fall to the bottom of the vertical conveying pipe 12;
in this embodiment, as shown in fig. 3, a flange stop collar 4 for preventing the stop ball 3 from escaping is installed at the outlet end of the lateral liquid outlet pipe 11; specifically, the outlet end of the lateral liquid outlet pipe 11 is formed with a flange bottom plate 2, the flange limit ring 4 is fixed on the flange bottom plate 2 through a bolt, and a limit hole with an inner diameter smaller than the diameter of the limit ball 3 is formed in the flange limit ring 4, so that when the liquid in the vertical conveying pipe 12 is conveyed from bottom to top, the liquid pushes the limit ball 3 to be blocked in the flange limit ring 4, and the liquid is prevented from being discharged from the lateral liquid outlet pipe 11;
in this embodiment, an inlet and outlet retainer ring 5 for preventing the limiting ball 3 from falling is installed at the lower port of the vertical conveying pipe 12; the inner diameter of the inlet and outlet check ring 5 is smaller than the diameter of the limit ball 3;
as shown in fig. 4, when the liquid in the vertical conveying pipe 12 is conveyed/discharged downwards from top to bottom, the limiting ball 3 is automatically blocked in the inlet and outlet check ring 5 by self gravity, so that the liquid is prevented from being discharged from the vertical conveying pipe 12, and the lateral liquid outlet pipe 11 is used as a single discharging port, so that vertical automatic discharging is realized.
In this embodiment, the r-shaped check valve is applied to a cleaning device inside a liquid tank, and may be specifically applied to a cleaning pipeline of a milk tank, where the limit ball 3 is a food-grade limit ball.
As shown in fig. 5, a limiting post 6 for preventing the limiting ball 3 from escaping upwards is also installed in the vertical conveying pipe 12; if the flow rate of the liquid in the vertical conveying pipe 12 is too high, the limit ball 3 is directly flushed into a pipeline above the vertical conveying pipe 12; the limit column 6 is used for enabling the limit ball 3 to smoothly enter the lateral liquid outlet pipe 11 and be blocked at the flange limit ring 4; a baffle 6a for preventing the limit ball 3 from escaping upwards is further installed in the vertical conveying pipe 12, wherein the vertical conveying pipe 12 is divided into two conveying flow passages by the baffle 6a, and meanwhile, the limit ball 3 can be prevented from blocking the vertical conveying pipe 12 upwards.
Application example
The method can be applied to the internal cleaning equipment of the milk tank;
the internal cleaning equipment comprises a main cleaning water pipe arranged in a milk tank, a plurality of auxiliary cleaning water pipes which are arranged in the milk tank and are communicated with the main cleaning water pipe, and cleaning spray heads respectively arranged at the water outlet ends of the auxiliary cleaning water pipes;
the conventional cleaning equipment is arranged in the milk tank, and the cleaning main water pipe and the cleaning auxiliary water pipe are still communicated with the interior of the milk tank when the cleaning main water pipe and the cleaning auxiliary water pipe do not work; therefore, when discharging milk, the main cleaning water pipe and the auxiliary cleaning water pipe still intercept part of milk, and if the milk is not discharged in the main cleaning water pipe and the auxiliary cleaning water pipe, fermentation can be caused to influence the conveying of the follow-up fresh milk;
based on the above, the r-shaped check valve can be arranged at the lowest end of the main water pipe in the milk tank;
when the milk tank needs to be cleaned, the water supply end is communicated with the lower end of the vertical conveying pipe 12, and then the liquid is pushed to push the limiting ball 3 to be blocked in the flange limiting ring 4, so that the liquid is prevented from being discharged from the lateral liquid outlet pipe 11, and cleaning spray water is conveniently and continuously supplied to a cleaning main water pipe and a cleaning auxiliary water pipe;
after the milk tank is cleaned, an external valve is opened to empty the cleaning main water pipe and the cleaning auxiliary water pipe to accumulate water;
when the milk tank needs to discharge milk, the main cleaning water pipe and the auxiliary cleaning water pipe are communicated with the milk tank, so that part of milk is trapped;
wherein the vertical conveying pipe 12 is closed when the valve is externally connected during milk discharging, and the lower end of the vertical conveying pipe 12 is regarded as a blind pipe based on the closed valve;
the limiting ball 3 slides down by self gravity and is automatically blocked in the inlet and outlet check ring 5 to prevent liquid from being discharged from the vertical conveying pipe 12, so that the lateral liquid outlet pipe 11 serves as a single drain port, and the main cleaning water pipe and the auxiliary cleaning water pipe are automatically emptied of milk along with the lowering of the milk liquid level through the vertical conveying pipe 12 and the lateral liquid outlet pipe 11 vertically.
The foregoing embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to which the present invention pertains should fall within the scope of the invention as defined in the appended claims without departing from the spirit of the invention.
