Embodiment 1

[0034] A flow control valve with anti-corrosion 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 with 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 flange 2 on the right side is fixedly connected with the right side of the pipeline 1, and 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 arranged on the inner wall of the pipeline 1. The polytetrafluoroethylene layer 301 is named "Teflon", referred to as PTE or F4 , commonly known as the king of plastics, is one of the most corrosion-resistant materials in the world today. The polytetrafluoroethylene layer 301 is sprayed together wi...

Embodiment 2

[0036] As an option, see Figure 1-4 , a flow control valve with anti-corrosion 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 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 polystyrene foam plastic layer 401 is provided with a rigid polyurethane foam plastic layer 402, which has good thermal insulation effect, light weight, high specific strength, and convenient construction. Sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, solvent resistance, etc., the inner wall of the polyurethane rigid foam plastic layer 402 is bonded with the molded polys...

Embodiment 3

[0039] As an option, see figure 1 , 5and 6, the flow control valve with anti-corrosion function, the top of the pipeline 1 is provided with a control mechanism 5, the control mechanism 5 includes a box body 501, a first rubber pad 502, a valve body 503, a through hole 504, a threaded hole 505, a slide Rod 506, screw rod 507 and first handle 508, the box body 501 communicates with the top of the pipeline 1, the inner wall of the box body 501 is provided with a first rubber pad 502, the first rubber pad 502 is sleeved on the inner wall of the box body 501, the first rubber pad The inner wall of the bottom 502 is interference-fitted with a valve body 503, and the outer wall of the valve body 503 fits closely with the inner wall of the pipeline 1, so that the valve body 503 can seal the pipeline 1, and the top left side of the valve body 503 is provided with a through hole 504, Valve body *503. A threaded hole 505 is provided on the top of the through hole 504, and a slide bar 5...

Abstract

The invention discloses a flow regulation and control valve with an anti-corrosion function. The flow regulation and control valve comprises a pipeline, wherein flanges are arranged on the left side and right side of the outer wall of the pipeline; the left side of the flange on the right side is fixedly connected with the right side of the pipeline; an anti-corrosion layer is arranged on the inner wall of the pipeline; a polytetrafluoroethylene layer is sprayed together with the inner wall of the pipeline; and a copper oxide layer is plated on the inner wall of the polytetrafluoroethylene layer. According to the flow regulation and control valve with the anti-corrosion function, the polytetrafluoroethylene layer and the copper oxide are good in acid and alkali corrosion resistance, the pipeline is prevented from conveying liquid for a long time, and then the liquid flow in the interior of the pipeline can be controlled stably; and the diameter of the outer wall of a first bevel gear is smaller than the diameter of the outer wall of a second bevel gear, so that a valve body is slowly ascended and descended while the first bevel gear drives the second bevel gear to rotate, and thenthe liquid flow rate is controlled according to the requirements of users.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a flow control valve with an anti-corrosion 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 liquids, the interior of the existing valve body does not have good corrosion resistance. After a long period of liquid transport, the interior of the valve body will be corroded by the liquid, resulting in damage to the valve body. problem, and the existing valve body has no thermal insulation, when the liquid is transported in cold winter, the liquid inside the valve body may freeze and cannot be transported. Contents of the invention [0003] The purpose of th...
