Embodiment 1

[0040]A flow regulating valve with a flow stop function, comprising a pipeline 1, flanges 2 are provided on the left and right sides of the outer wall of the pipeline 1, and the right side of the left flange 2 is fixedly connected to the left side of the pipeline 1, The flange plate 2 is used to connect the left and right ends of the pipeline 1 with the external delivery pipe, and the flange plate 2 on the right side is fixedly connected with the right side of the pipeline 1, and the left side of the pipeline 1 is provided with a flow stop mechanism 9 The flow stop mechanism 9 includes a sealing sleeve 901, a telescopic rod 902, a rotating handle 903, a fixed plate 904, a slot 905, a limit post 906, a horizontal plate 907, a torsion spring 908, a block 909 and a through-hole plate 910; The shaft sleeve 901 is connected to the top left side of the pipe 1. The top of the sealing shaft sleeve 901 is provided with a fixed plate 904. Rod 902 is rotatably connected to pipe 1 through...

Embodiment 2

[0042] As an option, see Figure 1-2 , the inner wall of the pipeline 1 is provided with an anti-corrosion layer 3, the anti-corrosion layer 3 includes a polytetrafluoroethylene layer 301 and a copper oxide layer 302, the polytetrafluoroethylene layer 301 is located on the inner wall of the pipeline 1, and the polytetrafluoroethylene layer 301 is named "Teflon", abbreviated as PTE or F4, commonly known as the king of plastics, is one of the most corrosion-resistant materials in the world today. The PTFE layer 301 is sprayed together with the inner wall of the pipe 1. Copper oxide layer 302 is plated on the inner wall, and the copper oxide layer 302 has a chemical formula of CuO, which is a black oxide of copper and has good corrosion resistance.

[0043] The solution in this embodiment can be selectively used in combination with the solutions in other embodiments.

Embodiment 3

[0045] As an option, see Figure 1-4 , a flow control valve with a stop-flow function, the outer wall of the pipeline 1 is provided with an insulation layer 4, the insulation layer 4 includes a molded polystyrene foam layer 401, a polyurethane rigid foam layer 402 and an acrylic waterproof coating 403, the molded The molded polystyrene foam layer 401 is sleeved on the outer wall of the pipe 1.

Abstract

The invention dislcoses a flow regulation and control valve with a flow stopping function. The flow regulation and control valve with the flow stopping function comprises a pipeline, wherein flange plates are arranged at the left side and the right side of the outer wall of the pipeline separately; the flange plate at the right side is fixedly connected with the right side of the pipeline; a transverse plate is connected to the lower part of a telescopic rod; a torque spring is wound around the telescopic rod; the upper end of the torque spring is fixedly connected with the lower side wall ofthe transverse plate; a clamping block is connected to the lower end of the torque spring; a through hole plate is arranged at the left side of the clamping block; the outer wall of the through hole plate and the left side of the inner wall of the pipeline are connected together in a sleeving manner; and the clamping block deflects under the pressure of water flow in the pipeline, and is enabled to be in parallel clearance fit with the through hole plate in the pipeline, and water flowing from the pipeline at the right side to the pipeline at the left side can be stopped, so that a flow stopping effect is achieved; and moreover, the clamping block counteracts a part of the pressure of the water flow under the elastic acting force of the torque spring, so that the service life of the flow stopping mechanism is prolonged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a flow control valve with a flow stop function. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Although the existing valve body can transport liquid, it cannot stop the flow when the valve is damaged, resulting in a lot of waste of water resources. The interior of the existing valve body does not have good corrosion resistance. After a long period of liquid transport, The inside of the valve body will be corroded by the liquid, causing damage to the valve body, and the existing valve body has no insulation. When the liquid is transported in cold winter, the liquid inside the valve body may freeze, making it imp...
