advantages and disadvantages of gate valves
S-shaped GATE VALVE and the valve of the advantages and disadvantages.GATE VALVE concrete fuel dispenser of the main advantages of simple structure, easy maintenance, for the force, suction is good, unlike the requirement of concrete S-shaped concrete pipe valve as high fuel dispenser, fuel dispenser may be sent from the mixed concrete ( adapt to low slump concrete fuel dispenser delivery): But by the GATE VALVE seal structure of capped, sealed low pressure, in the construction inevitably need to use Y-shaped tube to connect to dual fuel dispenser concrete block and transmission tube, while the Y-shaped tube will result in greater pressure loss. Also when using transmission gate valve, also called for the installation of vertical pipes in the front section of a horizontal pipeline, the length of concrete lifting height of 1 / 2. Because the gate of the vertical concrete caused by fluid pressure generated by the return of a great sensitivity to the formation of hydraulic resistance, and this resistance will reduce the height of the delivery of concrete, which is the gate valve concrete are highly affected by the delivery of fuel dispenser One of the main factors limit.
