Problems solved by technology

[0003] In the actual use of the existing butterfly valve, because the internal crude oil contains more solid impurities, if the crude oil in the valve is not treated, it will fail or be blocked because the crude oil in the valve is too thick, and the excessive water flow in the block will cause the valve to break down. Reduced effect, poor practicability

Embodiment

[0035] Embodiment: When using the butterfly valve, by twisting the valve button 1, it is possible to control whether the valve body 4 is on or off. The extruding device 2 is used to squeeze the solid petroleum sludge deposited inside the valve body into pieces for easy collection. When the device is overhauled, the valve button 1 is first turned into a closed state, and the biopsy plug can be opened at this time. At this time, the maintenance worker is put into the inside of the valve body 4 from the overhaul tank to overhaul the internal components. The overhaul process is convenient and easy to overhaul. When it is finished, just close the biopsy plug, and take out the maintenance tool at this time; when the butterfly valve is used normally, since the crude oil in the oil field contains more impurities such as sediment, when these impurities flow in the valve body 4, they will pass through Abrasive shell 23 is trapped on one side of abrasive trough 231. At this time, impuriti...

Abstract

The invention discloses a fluorine-lined butterfly valve, which includes a valve body. A jaw block is provided, the cross-section of the jaw block is L-shaped, and an inspection groove is opened on the inner side of the jaw block. The interior of the inspection groove and the valve body communicate with each other, and the contact between the inspection groove and the valve body A biopsy plug is arranged on the surface, and the extruding device includes an outer shell, and the inside of the outer shell is fixed with an abrasive shell by bolts. The abrasive shell is a hollow structure, and the top of the abrasive shell is provided with a Abrasive trough, the top of the abrasive shell is fixed with a power end by welding, the two sides of the power end are correspondingly connected with connecting rods, and one end of the connecting rod is connected with a extrusion roller, and the extrusion roller and the abrasive trough are The matching structure of the present invention has the characteristics of strong practicability and good suction filtration effect.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a fluorine-lined butterfly valve. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. Butterfly valves can be used to control the flow of fluids such as air, water, steam, etc., and mainly play the role of cutting off and throttling the pipeline. The opening and closing part of the butterfly valve is a circular disc version, which rotates around its own axis in the valve body to achieve the functions of opening, closing and adjustment. [0003] In the actual use of the existing butterfly valve, because the internal crude oil contains more solid impurities, if the crude oil in the valve is not treated, it will fail or be blocked because the crude oil in the valve is too thick, and the excessive water flow in the block will cause the valve to break...
