Abstract
The utility model discloses a lower valve body of a large gate valve for cement and metallurgical industries, which comprises the lower valve body, a connecting square flange, a cavity body, a circular-opening short sub, a gap adjusting ring, a supporting seat and a valve plate. The lower valve body is connected with the connecting square flange, the supporting seat is arranged at the bottom of the lower valve body, the circular-opening short sub is arranged in the cavity body of the lower valve body, and the gap adjusting ring is arranged between the valve plate and the lower valve body and located in the cavity gap of the lower valve body. The lower valve body of the large gate valve for the cement and metallurgical industries is convenient, reliable, convenient in manufacture, easy to control and low in production cost.
Description
Technical field
The utility model relates to valve body under a kind of gate valve, is specifically related to a kind of cement, metallurgical industry with valve body under the large-scale gate valve.
Background technique
Cement, metallurgical industry are weldment with valve body under the large-scale gate valve, and the gap between valve body and the valve plate is difficult to guarantee, excesssive gap, and the internal leakage rate does not reach requirement; Though the too small internal leakage rate in gap can reach requirement, because of valve plate also is a weldment, has welding deformation, and is stuck easily; If adopt machined into, can reach requirement fully, but cost be too high.At present domesticly lack valve body under the large-scale gate valve that economic and reliable addresses this problem.
Summary of the invention
The purpose of the utility model is in order to solve the deficiency of existing technology, a kind of economy to be provided, and the cement that the reliability price ratio is high, metallurgical industry are with valve body under the large-scale gate valve.The technological scheme that the utility model adopts is: a kind of cement, metallurgical industry are with valve body under the large-scale gate valve; Comprise valve body, connecting part's flange, cavity, round mouth short circuit, accent crack ring, bearing and valve plate down; Said valve body down is connected with connecting part's flange, and the bottom of following valve body is equipped with bearing, is provided with the round mouth short circuit in the cavity of following valve body; Be provided with between said valve plate and the following valve body and transfer the crack ring, transfer the crack ring to be installed in the lower valve body cavity crack.
As preferably, said accent crack ring connects band steel circle circle part for essence.
Said accent crack ring can guarantee low internal leakage rate, and be difficult for stuck according to the adjustment of the gap between valve body and valve plate size.
The beneficial effect of the utility model: convenient and reliable, be convenient to processing, control easily, cost of production is low.
