KYP-eccentric reducer rubber joint

KYP-eccentric reducer rubber joint

KYP eccentric reducer rubber joint
KYP eccentric reducer rubber joints are improved on the basis of KXT rubber joints, which can solve the problems of different calibers and different pipes in the connection of metal pipes. The eccentric reducer rubber joint can solve the problem of different calibers when the metal pipe is connected, and has the function of shock absorption and noise reduction, which can save the pipe installation parts and save cost. It consists of an inner rubber layer, a fabric reinforcement layer, a middle rubber layer, an outer rubber layer, an end reinforcing metal ring or a wire ring, and a metal flange. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, good noise reduction and convenient installation.
Eccentric reducer rubber joints can be widely used in water supply and drainage, circulating water, HVAC, fire, paper, pharmaceutical, petrochemical, ship, water pump, compressor, fan and other pipeline systems. General class: Suitable for conveying water with a temperature of -20~115 °C, acid solution or alkali solution with a concentration of 10%. There are also special rubber types required for special pipes: oil, high temperature, ozone, abrasion or chemical resistance.

[Product Certification]: ISO9001-2008
1. Pipe or pump valve installation eccentric head is used to prevent cavitation, and the size of the pump inlet should generally be installed horizontally. This is to prevent the gas in the pipe from accumulating at the pump port, forming large bubbles into the pump cavity and damaging the pump. . Only one case can be installed on the bottom. That is the elbow that is directly bent upwards behind the head. In this case, it is impossible to accumulate in the gas phase.
2. Pump-pipe installation reducer: There is a difference between the pump outlet and the outer pipe system. It is used for different diameter heads and can realize the straight connection of two pipes of different sizes.
The lateral displacement of the eccentric reducer rubber joint is: the displacement of the rubber joint in a direction perpendicular to the direction of the fluid, that is, the direction of the central axis.
The angular displacement of the eccentric reducer rubber joint is the sum of the angle between the vertical center line of the two end faces of the rubber joint and the original central axis.
product instructions:
First connect the joint flange with the corresponding flange hole of the corresponding pipe, then pass the fixing screw through the flange hole and lock the nut with the wrench.
1. This product can greatly reduce the vibration and noise of the pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and distraction of various pipelines.
2. According to different materials, it can be made into various varieties such as acid, alkali, corrosion, oil and high temperature, and adapt to various media and environment.
3. The material is polar rubber, good in sealing, light in weight, convenient in installation and maintenance, and long in service life, but avoid contact with sharp metal instruments to avoid puncturing the sphere.
4. If the overhead is used, it can be equipped with elastic brackets. When installing, the bolts should be tightened diagonally.
5. If the line pressure is too high, apply the limit bolts to connect the flanges at both ends.
6. The flange connection standard adopts GB/T9115.1-2000 standard. If other standards are used, it can be separately stated. The working pressure rating of this product is 0.6MPa, 1.0MPa.
7. The normal application of rubber joints is ordinary water with temperature of 0-60 °C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard texture, rubber should be selected according to special materials. Connector, can not be used blindly or universally.
