Abstract
The invention belongs to the technical field of machine manufacturing, and particularly relates to a gate valve. The gate valve comprises a valve body, a cylinder, a guide rail, a connecting rod, a compression rod, a valve plate and a guide wheel, wherein the valve plate and the connecting rod are connected with the compression rod; the compression rod is provided with a guide wheel which is arranged in the guide rail; a fitted sawtooth sealing structure is arranged between the valve body and the valve plate; at least two sawteeth of the sealing structure is arranged; and a sealing pad is arranged on the sawtooth surface with the sealing structure. According to the gate valve, the sealing structure is arranged between the valve plate and the valve body, so that the gate valve can be tightly sealed; besides, by adopting the sealing pad, the sealing effect is further improved, the precision and the efficiency of the equipment are improved, the valve body can not be eroded by contents easily, and the service life of the gate valve is prolonged.
Description
Technical field
The invention belongs to machinery manufacturing technology field, particularly relate to push-pull valve.
Background technique
At present, push-pull valve is widely used in the furnace apparatus of chemical industry, machine building industry and all trades and professions.The sealing effect of push-pull valve to push-pull valve itself even the technique effect of integral device play vital meaning.The ring structure of push-pull valve of the prior art is comparatively simple, and sealing effect is often very undesirable, is having a strong impact on precision and the efficiency of equipment.Such push-pull valve, valve body itself also is easy to be subject to the erosion of content, and working life is shorter.
Summary of the invention
Technical problem to be solved is to overcome the defect that prior art exists, and the push-pull valve that a kind of sealing effect is good is provided.
The technology used in the present invention solution is push-pull valve, comprise valve body, cylinder, guide rail, connecting rod, depression bar, valve plate, upper saw pulley, described valve plate is connected with depression bar with connecting rod, described depression bar is provided with upper saw pulley, upper saw pulley is arranged in guide rail, has the zigzag fashion sealing configuration agreed with mutually between valve body and valve plate.
At least 2 of the sawtooth numbers of described sealing configuration, the serrated surface of described sealing configuration is provided with seal rubber pad.
Compared with prior art, the beneficial effect that the present invention has is: the present invention is by the sealing configuration arranged between gate valve plate and valve body, make push-pull valve there is good sealing, seal rubber pad in structure has further improved sealing effect, precision and the efficiency of equipment have been improved, make valve body itself be difficult to be subject to the erosion of content, extended the working life of push-pull valve.
