Problems solved by technology
[0004] The present invention mainly provides a sprinkling valve that integrates manual and automatic operation, is simple and convenient to operate, has good reliability and long service life, and solves the problems existing in the prior art when the asphalt sprinkler or road sprinkler is spraying. Can only use ordinary valves, poor reliability, short service life and other technical problems
[0005] The present invention mainly also provides a spraying device with a high degree of automation, which can close any nozzle according to the use situation and automatically control the synchronous switch of the selected nozzle, which solves the problem of the asphalt sprinkler or road sprinkler in the prior art. During operation, it is impossible to switch the corresponding nozzles according to the road width or spraying operation requirements, resulting in technical problems such as waste of resources

Embodiment
[0028] Such as Figure 4 with 6As shown, a spraying device using a spray valve of the present invention includes a hollow horizontal spraying rod 17 with a square cross section. The horizontal spraying rod 17 communicates with the liquid storage tank through a pipeline. On the horizontal spraying rod 17 Four spray valves are arranged equidistantly along the length direction, and the liquid outlet 15 of the spray valve vertically penetrates downwards between the top surface and the bottom surface of the horizontal spray rod 17, as figure 1 As shown, the sprinkler valve includes a circular tubular valve body 1 and a valve stem 2 coaxially slidably inserted into the valve body 1. The upper and lower end surfaces of the valve body 1 are flush with the top and bottom surfaces of the corresponding horizontal spray rod 17, A ring-shaped bottom cover 14 is coaxially fixed outside the liquid outlet 15 corresponding to the lower end surface of the valve body 1. The bottom cover 14 is ...

The present invention discloses a valve and spraying device with the valve, which provides a manual self -integration, good stability, long service life, and can turn off any spray valve and automatically control the spray valve and the spray valve and the synchronous switching valve of the spray valve.The spray valve spraying device is used to solve the asphalt sprinkler or road sprinkler existing in the existing technology. When spraying operations, only ordinary valves can be used.The technical problem, the spray valve includes the valve body and sliding the valve stem that is inserted in the valve body. One end of the valve stem extends to the valve body and is blocked on the outlet.The bumper cover plate is set on the outer ring surface of the bun cover plate with an extended spiral positioning slot. Sliding in the spiral positioning slot is connected to one end of the bunter.On the support plate outside the valve, there is also a rocker arm on the split.
Description
technical field [0001] The invention relates to a valve and a spraying device using the valve, in particular to a manual spray valve and a spray valve that can automatically control the synchronous switch of the selected nozzle and can close any selected spray valve according to the need. sprinkler. Background technique [0002] In the spraying device of the existing asphalt sprinkler or road sprinkler, a horizontal spray bar is often arranged at the rear and lower part of the asphalt sprinkler or road sprinkler, and the front of the horizontal spray bar is connected to the asphalt sprinkler or road. The liquid storage tanks on the sprinkler are connected, and several nozzles are set horizontally under the horizontal spray rod, and then the cylinder drives all the valves to open or close at the same time, that is, the operation can only be carried out according to the spray width set by the car body, but in Due to the difference in road width during actual use, it cannot be...
