Abstract
The utility model relates to a glass fiber reinforced plastic flap valve which comprises a glass fiber reinforced plastic valve plate 3, a glass fiber reinforced plastic valve seat 1, a stainless steel hinge 4 and a rubber sealing ring 2, wherein the glass fiber reinforced plastic valve plate 3 is arranged on the glass fiber reinforced plastic valve seat 1; a pressing plate used for fixing the glass fiber reinforced plastic valve plate 3 is connected with the glass fiber reinforced plastic valve seat 1 through the stainless steel hinge 4; the end of the glass fibre reinforced plastic valve seat 1 is provided with a seal groove in which the rubber sealing ring 2 is arranged; the glass fibre reinforced plastic valve plate 3 and the glass fibre reinforced plastic valve seat 1 are respectively formed by compounding a structure layer 5 and a reinforced layer 6. The structure layer 5 is positioned at the center position with a thick wall of the glass fibre reinforced plastic valve plate 3 or the glass fibre reinforced plastic valve seat, and the outer side of the structure layer 5 is coated with the reinforced layer 6; the structure layer 5 is composed of the mixture of resin, sandstone and glass reinforcing bars or adopts a glass fiber reinforced plastic honeycomb structure; the reinforced layer 6 is composed of resin, glass fibres and glass fibre fabric. The glass fiber reinforced plastic flap valve provided by the utility model has the advantages of good strength, corrosion resistance and low cost.
Description
Technical field
The utility model relates to the flap valve (safety check) in order to prevent that river, river, tidewater etc. from pouring in down a chimney.Especially the composite material flap valve that a kind of intensity is good, corrosion-resistant, cost is low.
Background technique
At present, flap valve is widely used in the outlet port in various pipelines such as municipal water supply draining, sewage treatment project, industrial pipeline and water channel road.In order to prevent medium counter flow, be a kind of device that relies on the interior outside pressure difference of flap valve to realize opening and closing automatically.It makes material is not that cast iron is exactly steel.Cast iron and steel long period of soaking are in water, and corrosion resistance is quite limited, and particularly seawater is particularly serious to the etch of cast iron and steel, so that use department all will be arranged in non-flood season every year or other suitable period is checked, keeps in repair, maintains this type of flap valve.The flap valve made from steel corrosion-resistant not only cylinder iron, and be easy to stolen.This also is a major reason using department often to repeat to purchase over the years.In order to solve the corrosion-resistant problem of flap valve, the stainless steel flap valve has appearred again on the market, though the stainless steel flap valve is corrosion-resistant, cost will increase several times, and the easier target of being stolen that becomes.
The purpose of this utility model be cast iron, the steel flap valve at present use easily get rusty, easily stolen; The stainless steel flap valve is easily stolen, and the problem that cost is high provides the glass fibre reinforced plastic check valve that a kind of intensity is good, corrosion-resistant, cost is low.
Glass fibre reinforced plastic check valve described in the utility model is made up of glass fibre reinforced plastics valve seat, glass fibre reinforced plastics valve plate, stainless steel hinge and rubber seal four parts.
The glass fibre reinforced plastics valve plate is arranged on the glass fibre reinforced plastics valve seat.The pressing plate of fixing glass steel valve plate links to each other with the glass fibre reinforced plastics valve seat by the stainless steel hinge.The end of glass fibre reinforced plastics valve seat is provided with seal groove, and rubber seal is housed in the seal groove.
Described glass fibre reinforced plastics valve plate and glass fibre reinforced plastics valve seat are by construction layer and enhancement layer is compound constitutes.Construction layer is positioned at the center portion of glass fibre reinforced plastics valve plate or glass fibre reinforced plastics valve seat wall thickness, and the outside of construction layer is coated with enhancement layer.
Construction layer is made of the mixture of resin, sandstone and glass-fiber reinforcement, or adopts the frp honeycomb structure.
Enhancement layer is made of the fabric of resin, glass fibre and glass fibre.
Glass fibre reinforced plastic check valve intensity described in the utility model is good, corrosion-resistant, cost is low.
