The rubber petal stop valve is composed of valve body, valve cover, valve flap, and spring. It is mainly used to exit the pipeline exit of the industrial sectors such as water drainage systems, petroleum, and chemical industry to prevent the medium from flowing.Due to the tilt design of this product, the shutdown time is short, which can reduce the pressure of water hammer.The valve petals are suppressed by diced rubber and steel plates by high temperature. They are resistant to brushing and have good sealing performance. The product structure is simple, maintenance, maintenance, and transportation are very convenient.

Rubber petal stop valve function
1. The rubber petals in the valve are made of steel plates, steel rods and reinforcement nylon cloth. The outer layer is made of rubber, and the life of the valve petals can reach 1 million times.The H44X (SFCV) series of rubber flap stop valve is designed with a full -current area, which has the characteristics of small water head loss, not easy to accumulate debris, and simple maintenance.2. The rubber flap stop valve is mainly suitable for the water supply drainage system for the horizontal installation. It can be installed at the water outlet of the pump to prevent the backflow and the water hammer from damage to the pump.The H44X (SFCV) series of rubber flap stop valves can also be installed on the bypass pipe of the inlet and out of the water pipe of the reservoir to prevent the pond water from flowing into the water supply system.The stop valve is generally suitable for a clean media, and it should not be used in the medium that contains solid particles and large viscosity.
Principle
The working characteristics of the rubber flap stopping valve are that the load is large, the frequency of the opening and closing is small, and when it invested in a closed or open state, the combined cycle is very long, and the motion component movement is not required.But once the "switching" requirement, it is necessary to move flexible. This requirement is more harsh than the common mechanical movements.Because the rubber petal stop valve is used in most actual use, it is qualitatively determined to be used for rapid closure. At the moment when the rubber petone stopping valve is closed, the medium is directed.It drops to zero, and the pressure rises rapidly, that is, the "water hammer" phenomenon that may have a destructive effect on the pipeline system.For the high -voltage pipe system used by multiple pumps and combined, the water hammer problem of the rubber petal stop valve is even more raised.Water hammer is a kind of pressure wave in the transient change activity in the pressure pipeline. It is a hydraulic impact of pressure rising or decreased due to changes in fluid flow rates in the pressure pipeline.The physical cause of the rubber flap stopping valve is the comprehensive effect of fluids non -compressed, fluid motion inertia and pipeline elasticity.In order to prevent the hidden dangers of the water hammer in the pipeline, for many years, people have adopted some new structures and new materials in the design of the rubber flap stopping valve.The smallest aspects have made gratifying progress.
