Description
Technical Field
The utility model belongs to the technical field of irrigation, and particularly relates to a high-flow energy pressure-regulating stop valve for an irrigation system and an irrigation system device.
Background
The stop valve, also called stop valve, is the most widely used valve, because the frictional force between the sealing surfaces is small in the opening and closing process, the stop valve is relatively durable, the opening height is not large, the manufacture is easy, the maintenance is convenient, and the stop valve is not only suitable for medium and low pressure, but also suitable for high pressure.
The stop valve is an extremely important cut-off valve, the sealing of the stop valve is realized by applying torque to a valve rod, and the valve rod applies pressure to a valve clack in the axial direction, so that a sealing surface of the valve clack is tightly attached to a sealing surface of a valve seat, and the leakage of a medium along a gap between the sealing surfaces is prevented.
With the development of agricultural irrigation, a relatively fine irrigation mode such as pipeline irrigation, water-saving irrigation and water and fertilizer integration needs to be changed from a relatively rough channel irrigation mode. The pipeline that widely uses in agricultural irrigation at present is two kinds of irrigation tubular product of PVC and PE, and how supporting corresponding valve is the big problem that the value must be studied among the industry, and the valve kind commonly used in agricultural irrigation divide into butterfly valve, gate valve, ball valve, stop valve etc.. The more commonly used valves in the input line are butterfly valves and gate valves, each of which has advantages and disadvantages. And the water distribution pipeline has two types, namely a ball valve and a stop valve.
The ball valve controls the closing and opening of the valve by the rotation of a perforated metal or plastic ball in the valve body, and compared with a stop valve, the water passing amount is relatively large, for example, the diameter of the ball valve is 30cm by matching with DN63 PE pipe, and the diameter of the stop valve is 25 cm. And therefore its water throughput is greater than with a shut-off valve. But also has the technical problem that the valve cannot be maintained once being damaged.
The stop valve drives the sealing gasket to move up and down through the lifting rod of the valve core, and controls the opening and closing of the valve by closing or opening the water inlet through the sealing gasket, so that the stop valve is easy to maintain.
To sum up, the widely used ball valve and stop valve in the agricultural irrigation at present can not satisfy the requirement of pipeline irrigation, cause the pipeline extravagant.
