Abstract
A lifting stop valve is characterized in that all flow passage components are provided with a coating layer with the thickness of 0.5-1.5 mm, wherein the coating layer is formed by combining thermosetting melting and modified epoxy powder coating. The utility model discloses corrosion resistance is good, and is with low costs, is particularly suitable for jumbo size stop valve.
Description
The utility model relates to the valve technology, and a kind of lifting type stop valve is provided especially.
The lifting type stop valve is the very wide flow passage components of kind of application, under some special aggressive medium situation, has to make of stainless steel or corrosion resistant alloy, has increased cost greatly, when particularly required stop valve size is big.
The purpose of this utility model is to provide a kind of corrosion-resistant and large-scale lifting type stop valve that cost is low.
The utility model provides a kind of lifting type stop valve, flashboard (1) is driven by valve rod (2) and does elevating movement with closed gate, and it is characterized in that: all flow passage components all are provided with the coating (4) that a bed thickness is the thermosetting property adhere modified epoxy powder coating of 0.5～1.5mm.Thermosetting property adhere modified epoxy powder coating can be on metal construction melting and solidification to form a layer thickness even, the anti-corrosion corrosion resistant coating that surface finishment is good, itself and metal surface binding ability are fabulous.Thereby the stop valve major part can be made by Ordinary Steel, thereby reduces cost greatly.By embodiment in detail the utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, most of parts are all made of Ordinary Steel, evenly apply the commercially available SEBF thermosetting property of one deck adhere modified epoxy powder coating at all overcurrent positions.Thickness is 0.8mm, for avoiding between flashboard (1) and valve rod (2) because the damage that the mechanical shock that often has causes coating, do some structural improvement and part at this place and used corrosion resistant alloy, the underpart that is valve rod (2) is the corrosion resistant alloy spare (21) with a circle semicircle gap, other has corrosion resistant alloy cover (11) and the flashboard (1) of half garden gap in the band to screw togather, and valve rod (2) and flashboard (2) rely on a circle corrosion resistant alloy silk (3) of squeezing in the gap of corrosion resistant alloy spare (21) and corrosion resistant alloy cover (11) fixing.
Claims (2)
1. lifting type stop valve, flashboard (1) are driven by valve rod (2) and do elevating movement with closed gate, and it is characterized in that: all flow passage components all are provided with the coating (4) that a bed thickness is the thermosetting property adhere modified epoxy powder coating of 0.5～1.5mm.
2. carry only valve according to the described lifting type of claim 1, it is characterized in that: the underpart of valve rod (2) is the corrosion resistant alloy spare (21) with a circle semicircle gap, other has the anti-corrosion component cover (11) of half garden gap in the band to screw togather with flashboard (1), relies on a circle corrosion resistant alloy silk (3) of squeezing in the gap of corrosion resistant alloy spare (21) and corrosion resistant alloy cover (11) fixing between valve rod (2) and flashboard (2).
