Rubber ball is one of the special equipment used with vibration, so the world is known as the vibrating screen rubber ball, rubber elastic ball, rubber bouncing ball. The reason why it can be called the bouncing ball, is because the rubber ball itself has good elastic performance, can be in the middle of the vibrating screen screen ring jumping, and constantly # hit the net hole. The resulting action force can be attached to the net material mass down. Therefore, the main role of rubber ball is to clean up the screen and sieve adhesion of the material, improve the screening efficiency of the material, avoid material waste and mesh plugging, improve the output of products. At present, the vibrating screen rubber ball for such as food, medicine, mining, gold and other industries in the cleaning effect of viscous materials is very good, so the application range is wide. But in the process of use, it is also necessary to inject the density and proportion of the rubber ball on each screening equipment. If the rubber ball is too much, it may not only cause the loss of the equipment, but also pollute the material.

The butterfly valve (English: butter flyvalve) refers to the closing part (disc or butterfly plate) is a disc, revolving around the valve shaft to achieve the opening and closing of a valve, mainly used in the pipeline to cut off and throttle. Butterfly valve opening and closing parts is a disc shaped butterfly plate, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or adjustment. Butterfly valve fully open to fully closed is usually less than 90° butterfly valve and butterfly rod itself has no self-locking ability, in order to the positioning of the butterfly plate, to install worm gear reducer on the valve stem. Using worm gear domain speed device, not only can make the butterfly plate with self-locking ability, make the butterfly plate stop in any position, but also can change the valve performance. The characteristics of the industrial butterfly valve can withstand high temperature, the applicable pressure range is higher, the nominal diameter of the valve is large, the valve body is made of carbon steel, the sealing ring of the valve plate (the butterfly valve is sealed) is made of metal ring instead of rubber ring.

Gas-filled sealing ring

Silicone inflatable sealing ring is a kind of sealing technology results used under specific conditions, due to the complex manufacturing process of the finished product, higher requirements for the material, the qualified rate of the finished product is low, and the cross-section shape of the silicone inflatable sealing ring used in different occasions, circumference size, circumference direction are not the same, inflatable sealing ring from the cross-section shape see circular, rectangular, square, D type, C type, V type, M type and other types of inflatable sealing ring. The inflatable sealing ring is mainly used in the following situation, the gap seal between the large hatch and the hatch, the general circumference of the hatch is relatively large, affected by the processing and assembly accuracy or by the change of environmental temperature produced thermal expansion cold contraction deformation, resulting in the need to seal the gap is inconsistent or change, the range of change is generally in 3-5mm or even larger, It is difficult to achieve the ideal sealing effect by using ordinary sealing strips. In this case, it is necessary to have a kind of sealing products that can change with the gap. The inflatable sealing ring is a new sealing technology achievement developed successfully in order to meet the sealing requirements.

LBH

The principle of achieving "self-sealing" effect: The pressure type seal in the contact dynamic seal is the contact pressure formed between the seal and the coupling surface through the pressing force generated by the pre-compression force and the medium pressure. The higher the medium pressure, the greater the contact pressure, which makes the seal The parts are tightly fitted with the coupling to block the leakage channel and achieve a "self-sealing" effect. The self-sealing self-tightening seal uses the back pressure generated by the deformation of the seal itself to increase with the increase of the medium pressure, so as to achieve the "self-sealing" effect.

dome valve seal

The valve core of the dome valve is a spherical dome. During the opening and closing process of the dome valve, there is a gap of about 2mm between the valve core and the rubber sealing ring, so that the valve core and the rubber sealing ring can move in a non-contact manner. The purpose is to There is no friction between the valve core and the sealing ring to reduce wear. The pneumatic actuator of the dome valve is a fully enclosed rotary push rod type cylinder, which directly drives the dome valve to rotate, effectively preventing the occurrence of wear and leakage caused by dust entering it.

Phenolic cloth support ring

Special-shaped oil seal

Under the condition of low pressure, the U-shaped Y-shaped sealing ring only relies on the interference deformation of the lip to generate the seal. Due to the small contact area, the friction force is relatively low. As the pressure increases, the elastic deformation of the lip increases, stretching, When the compression and bending stress increases, the radial pressure of the U-shaped ring automatically increases, and the length of the contact with the sealing surface continues to increase until the entire axial length of the U-shaped ring is in contact with the sealing surface, thereby ensuring good sealing performance under high pressure. The U-shaped Y-ring is the most commonly used oil seal in hydraulic cylinders. It is a typical lip seal and can obtain a good seal whether it is used for the piston or the piston rod.
