Pneumatic butterfly valve of manufacturer's supply pump unit
Introduction to damper spring pneumatic butterfly valve:
Damping spring damper (ZTE type) Characteristics of damping spring pneumatic butterfly valve: the body is made of ordinary cast iron and ball cast iron. The body is hot-dip galvanized and has good weather resistance. Special structure design, height can be adjusted according to practical needs.
It is light and firm in appearance, easy to install, and suitable for internal vibration absorption installation of various machines. Springs are subject to heat treatment, ED rust prevention, paint baking and other procedures. The load deflection of 20mm and 40mm can effectively eliminate the vibration of mechanical structure. The anti slip rubber at the bottom is easy to install and has high safety, easy control and adjustment, which can effectively eliminate floor vibration and is cheap.
Damping spring pneumatic butterfly valve is mainly used: ZTE damping spring shock absorber is applicable to various water chillers, cooling towers, floor fans or floor air conditioning boxes and other equipment.
Description of damper spring pneumatic butterfly valve device: before damper spring damper device, please confirm whether the model, specification and model of damper are correct. The compression of the shock absorber is generally 10-25mm. After the shock absorber is placed in the correct position, it is necessary to remove the fixing bolts first, and then fix the fixed foot device of the equipment on the shock absorber. Fix the shock absorber with the foundation bolt first.
Adjust the height of the shock absorber to the extent of the equipment. Adjust the nut in a clockwise direction upward and counterclockwise direction downward, and then configure the receiving circuit after the degree is adjusted.

All hose makers know that this product is also a big one, with a large sales volume. Then customers will choose the right product according to their own industry, and then the needs of this PTFE lined hose in terms of model selection will be well explained! Then the details are as follows:
(1) The profile structure of the valve core is mainly based on the selected flow characteristics, unbalanced force and other factors.
(2) Wear resistance When the fluid medium is a suspension containing high concentration of abrasive particles, the joint surface of valve core and valve seat will be severely rubbed every time it is closed. Therefore, the flow path of the valve should be lubricated and the internal data of the valve should be hard.
(3) Corrosion resistance As the medium is corrosive, the PTFE compensator should try to choose a valve with simple structure when it can meet the conditioning function.
(4) Medium temperature and pressure When the medium temperature and pressure are high and vary greatly, select the valve whose valve core and valve seat data are subject to small changes in temperature and pressure.
(5) Teflon hose is lined to avoid flashing and cavitation flashing and cavitation only occur in liquid medium. In the process of practical consumption, flashing and cavitation not only affect the calculation of flow coefficient, but also constitute vibration and noise, which shortens the service life of valves. Therefore, flashing and cavitation should be avoided when selecting valves.
