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 2 is used to connect the left and right ends of the pipeline 1 with the external delivery pipe, the left side of the right flange 2 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 seal bushi...

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, molded The polystyrene foam layer 401 is sleeved on the outer wall of the pipe 1. The molded polystyrene foam layer 401 has excellent and durable thermal insulation, unique cushioning, shock resistance, aging resistance and waterproof performance. The outer wall of the ethylene foam layer 401 is provided with a polyurethane rigid foam layer 402, which has good thermal insulation effect, light weight, high specific strength, convenient construction, etc., and also has sound insulation and shock resistance. Electrical insulation, heat resistance, cold resistance, solvent resistance, etc., the inner wall of the polyurethane rigid foam layer 402 is bonded with the molded polystyrene...

Abstract

The invention discloses a flow control valve with a flow stop function, which includes a pipeline, flanges are arranged on the left and right sides of the outer wall of the pipeline, and the left side of the flange on the right side is fixedly connected to the right side of the pipeline. Together, the lower part of the telescopic rod is connected with a horizontal plate, the telescopic rod is wound with a torsion spring, the upper end of the torsion spring is fixedly connected with the lower side wall of the horizontal plate, and the lower end of the torsion spring is connected with a block, and the clamp There is a through-hole plate on the left side of the block, and the outer wall of the through-hole plate is socketed with the left side of the inner wall of the pipeline. The clamping block is deflected by the pressure of the water flow in the pipeline, so that the clamping block is parallel to the through-hole plate in the pipeline. Cooperating, it can hinder the water flowing from the right pipe to the left pipe, so as to stop the flow, and the block offsets part of the water flow pressure under the elastic force of the torsion spring, prolonging the service life of the flow stop mechanism.

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...
