Split-type proportional valve

The utility model discloses a split-type proportional valve which comprises a valve body and a filter net. The split-type proportional valve is characterized in that the valve body is of a split-type structure and is composed of an upper valve body and a lower valve body, the upper portion of a center hole in the upper valve body is an external connection connector connecting section, the filter net is embedded in the middle of the center hole in the upper valve body, a center hole in the lower valve body is a two-section stepped hole with the two large ends and the small middle, the middle diameter section of the center hole in the lower valve body is a flow limiting section, and the large diameter section at the lower portion of the center hole in the lower valve body is an external connection connector connecting section. When the upper portion of the lower valve body is inserted into the lower portion of the center hole in the upper valve body, the inserted portion is in threaded connection with the lower portion of the center hole of the upper valve body, and the center hole in the upper valve body and the center hole in the lower valve body are on the same straight line. Due to the fact that the split-type proportional valve is of the split-type structure, the upper valve body and the lower valve body can be split when needed, and then the filter net inside the center hole in the upper valve body is cleaned, so that normal use of the filter net is ensured, the defect that a whole proportional valve is scrapped due to the fact that a filter net cannot be used in the prior art is avoided, and the purpose of reducing the cost is achieved.
