Abstract
The invention relates to a locking preventive type gate valve device. The device comprises a valve block which is connected with an oil cylinder through a valve rod; a valve seat is arranged at the lower end of the valve block; a plurality of inclined V-shaped grooves are respectively arranged in two sides of the valve block. With the adoption of the locking preventive type gate valve device, excessive pulverized coal can be prevented from falling between the valve block and the valve seat, the valve block is prevented from being locked in the a clamping seat to cause failure of normal lifting, and the normal running of the gate valve is ensured; in addition, the device is simple to manufacture with few materials, and the convenience of production is improved.
Description
Technical field
The present invention relates to a kind of auxiliary device of chemical field, be specifically related to a kind of anti-jamming push-pull valve device of coal gasifier full-automatic coke feeder.
Background technique
In little nitrogen enterprise, automatically adding coke installation adopts more and more extensive, push-pull valve is the important component part of full-automatic coke feeder, current push-pull valve is valve seat and valve block Full connected form, because of the existence of foam coal in actual motion, valve block is stuck in valve seat of being everlasting can not normally mention, and have impact on the normal operation of equipment.
Summary of the invention
For above-mentioned situation, the object of this invention is to provide a kind of anti-jamming push-pull valve device, make simple, operate steadily, life cycle is long.
Technological scheme of the present invention is as follows: a kind of anti-jamming push-pull valve device, and comprise valve block, be connected by valve rod with oil cylinder, valve block lower end is provided with valve seat, is respectively equipped with " V " shape groove of some inclinations in the both sides of valve block.
Preferably, 2-3 " V " shape groove tilted is respectively equipped with in the both sides of valve block.
Anti-jamming push-pull valve device of the present invention, valve block is connected with oil cylinder by valve rod, valve block rises and falls under hydraulic oil cylinder driving, foam ribbing can go out by " V " shape groove in process that rises and falls, and prevent the foam coal between valve block and valve seat too much, valve block is stuck can not normally mention in deck, ensure the normal operation of push-pull valve, and this device makes simple, material requested is few, brings larger facility to production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of anti-jamming push-pull valve device, is comprised valve block 1, is connected by valve rod 3 with oil cylinder 2, and valve block 1 lower end is provided with valve seat 5, is respectively equipped with 2 " V " shape grooves 4 tilted in the both sides of valve block 1.
During concrete enforcement, valve block 1 rises and falls under oil cylinder 2 drives, and foam ribbing can go out by " V " shape groove 4 in process that rises and falls, and prevent the foam coal between valve block 1 and valve seat 5 too much, valve block 1 is stuck can not normally mention in valve seat 5.
Claims (2)
1. an anti-jamming push-pull valve device, is comprised valve block, is connected by valve rod with oil cylinder, and valve block lower end is provided with valve seat, it is characterized in that the both sides of described valve block are respectively equipped with " V " shape groove of some inclinations.
2. anti-jamming push-pull valve device according to claim 1, is characterized in that the both sides of described valve block are respectively equipped with 2-3 " V " shape groove tilted.
