by:Mech     2020-10-20

a lot of customers to purchase feeding valve, phone, often to show type feeding valve and the exhibition type feeding valve somewhat confused, the difference between a mountain of Shanghai valve factory for exhibition and the exhibition on the applicability of the material valve, the structure, size and torque are analyzed, and compared the development type feeding valve and show the difference between the type of feeding valve:

1, applicability

feeding Industrial Valves is mainly used in storage tank, reaction kettle and other emissions material on the bottom of the container, the valve with flange or butt welding connected to the equipment and at its bottom, eliminate the process medium in the export of container usually residual phenomenon. According to the need of the actual situation is divided into the upper made of exhibition, the exhibition; On exhibition of a mixer used for feeding valve reaction kettle feeding; And the exhibition type feeding valve used in frame anchor agitator reaction kettle feeding. Structure difference:

3, open-close torque difference

to type feeding valve disc on the upward movement of the valve is opened, when open the valve to overcome forces of medium, opens the closing torque. To try to feeding valve disc (under Plunger) Downward movement of the valve to open, open the direction when the reaction is the same with the media, thus relatively closed torque is small when they open them.

4, opening and closing of the difference between

open/close schedule, installation dimensions have size show type feeding Industrial Valves and the exhibition type feeding valve opening and closing stroke is small, the installation height is smaller. Feeding valve press plunger plunger type structure and movement mode is divided into two lifting rod and rotating rod structure form, the lifting rod structure form it requires a larger installation space, but can be based on the movement of the plunger and intuitive judgment of the valve opening and closing and location. Rotating rod structure minimum installation height, rotation of the plunger is only in the process of opening and closing, it should be based on with opening and closing position indicator to judge the valve opening and closing and position.
