Problems solved by technology
[0004] However, the connection mechanism of the existing system is complicated, and reciprocating motion is used at the same time. Under the action of frequent reciprocating force, the connecting rod and the motor shaft are prone to fatigue and fracture, which makes the spraying system have a high failure rate and a short service life.
In addition, the rotation structure of the existing double-layer bushing is complicated, and the mass of the follower is large, which makes the system response slow and difficult to seal, which not only causes waste of dust suppressant and pollutes the surrounding environment, but also leads It will also affect the normal operation of the train if it is blocked by the hook or sprayed on the track

Embodiment Construction
[0020] The specific embodiment of the present invention is illustrated below in conjunction with accompanying drawing:
[0021] see figure 1 , a special high-frequency response valve system for train transport spraying, including: a motor 1, a motor seat 2, a coupling 3, a shaft valve 4, a bearing seat 5, a shaft seat 6 and a bottom plate 7. The motor 1 is installed on the motor base 2, and the motor base 2, the bearing base 5 and the shaft base 6 are fixed on the bottom plate 7 by several nuts 701.
[0022] see figure 1 and figure 2 , the shaft valve 4 is provided with a driving connection part 401, a central shaft 402 and a liquid control part 403, and the driving connection part 401 and the liquid control part 403 are respectively arranged at two ends of the central shaft 402; the liquid control part 403 The inner diameter is larger than the inner diameter of the central shaft 402 , so that the junction of the central shaft 402 and the liquid control part 403 forms a sh...

The invention belongs to the field of spraying systems and particularly relates to a high-frequency response valve system special for train transportation spraying. The high-frequency response valve system special for train transportation spraying comprises a bottom board, a motor, a shaft valve and a shaft base, wherein the motor and the shaft base are fixed to the bottom board; a drive connection part, a middle shaft and a liquid control part which are connected with the motor are sequentially arranged from the top end of the shaft valve; an axially inward liquid storage cavity is formed in the tail end of the liquid control part, and the side of the liquid storage cavity is provided with a liquid inlet; the shaft base covers the liquid storage cavity, a liquid inlet pipe is arranged on the side of the shaft base, and the axial position of the liquid inlet pipe corresponds to the axial position of the liquid inlet; a spraying connector piece is arranged at the tail end of the liquid storage cavity. The motor drives the shaft valve to rotate to adjust the superposition area of the liquid inlet pipe and the liquid inlet, so that the valve system is controlled to be opened or closed. As a driven piece is small in mass and size, the valve system has the advantages of being short in response time, long in service life, capable of accurately spraying liquid to appointed areas, and the like.
Description
technical field [0001] The invention belongs to the field of spraying systems, in particular to a special high-frequency response valve system for train transport spraying. Background technique [0002] Coal is an organic mineral with a certain hardness and brittleness. It forms pulverized coal during the crushing process. Dust and dust during transportation are inevitable. In addition to causing coal loss, it will also cause air pollution. During the transportation of coal, often It is necessary to adopt some methods of dust suppression to reduce the loss of coal and reduce the pollution to the atmosphere. [0003] At present, the dust suppression method of spraying dust suppressant is mostly used in the process of coal transportation in China. The existing spraying system adopts a double-layer casing, and the outer tube rotates back and forth to form a shield to realize the opening and closing of the spraying system. [0004] However, the connection mechanism of the exis...
