Raw material formula and production method of electric butterfly valve rubber
The invention discloses a raw material formula and a production method of an electric butterfly valve skin capsule rubber, which comprises a raw material formula and a production method. The invention adopts the technical scheme that cigarette rubber and chloroprene CR3222 are respectively plasticated in an open mill, and then mixed together with vulcanizing agent and other additives in an internal mixer. The utility model solves the problems that the electric butterfly valve produced by the prior art has large performance variation, is easy to scorch, is easy to delaminate, and has poor bending resistance, flexibility, and aging resistance cracking performance. The bag glue obtained has good adhesion, no delamination, strong heat dissipation, ozone resistance, aging resistance, flame resistance, oil resistance, and longer service life.

The electric butterfly valve of "Lanshan 2B14-468 Electric Butterfly Valve" is an electric butterfly valve. The electric butterfly valve is used to isolate the interference of the external environment on the imprint lithography machine, which can protect the imprint lithography machine from the interference caused by external noise and vibration. The flange sealing forms of the end and connecting plate of the electric butterfly valve are: LHF, JBF, GF, HF and ZF.
"Lanshan 2B14-468 electric butterfly valve" is classified according to the structure and function of the air butterfly valve. The air butterfly valve includes free air butterfly valve, self-locking air butterfly valve, traction air butterfly valve, free stop air butterfly valve, swivel chair air butterfly valve, air bar, damper, etc. The product is widely used in automobile, aviation, medical equipment, furniture, machinery manufacturing and other fields. The advantages of electric butterfly valve, such as high frequency vibration isolation, sound insulation and low natural vibration frequency, can better realize vibration isolation and ensure the safety and stability of the base and control system of vibration equipment. Therefore, electric butterfly valve is widely used in equipment such as vibration isolation of vibrating screen and vibration reduction of luxury vehicle seats. On the rear suspension of Mann, Lilan and other buses, the A-frame structure is adopted, and the electric butterfly valve is arranged near the rear wheel, which increases the center distance of the butterfly valve and improves the anti roll ability of the car. Therefore, some people call the electric butterfly valve so arranged as the anti roll suspension.

Vibration isolation design and performance analysis of electric butterfly valve
Imprint lithography machine is a kind of precision instrument, and the external environment excitation has a great impact on the imprint lithography machine. The electric butterfly valve is a kind of electric butterfly valve. The electric butterfly valve can isolate the interference of the external environment on the imprint lithography machine, which can protect the imprint lithography machine from the excitation of low-frequency excitation force. This paper describes the vibration isolation principle of the single degree of freedom vibration isolation system of the low-frequency electric butterfly valve of the imprint lithography machine, and determines the rigidity of the electric butterfly valve and the natural frequency of the vibration isolation system, The theoretical results of the natural frequency and vibration isolation efficiency of the vibration isolation system are consistent with the experimental results of the actual vibration isolation system, indicating that the low-frequency vibration isolation design of the imprint lithography machine is reasonable and feasible.
