Description

Technical Field

[0001] This utility model relates to the field of clean air conditioning control technology, and in particular to a valve that allows observation of the internal mechanism status. Background Technology

[0002] During the commissioning of differential pressure and airflow in cleanroom air conditioning systems, the regulating mechanism of conventional galvanized manual regulating valves is in a closed state, making it impossible to directly observe the valve's internal opening status during commissioning or maintenance. Operators must rely on external dial indicators or manually rotate the valve to indirectly judge its status through differential pressure feedback. This can easily lead to inaccurate differential pressure regulation due to discrepancies between the dial and the actual position of the internal mechanism. Especially during the cleanroom differential pressure commissioning phase, the lack of transparency regarding valve status significantly increases troubleshooting time and may even affect system acceptance efficiency. Utility Model Content

[0003] The technical problem this invention aims to solve is that the opaque status of traditional valves leads to inaccurate actual adjustment operations, significantly increases troubleshooting time, and even affects system acceptance efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a valve that can observe the internal mechanism status, including a valve body, a control component installed on the valve body, the control component including a valve stem movably installed on the valve body and a valve plate assembled inside the valve body, a side-mounted glass observation window fixedly installed on the side wall of the valve body at the valve stem connection end, an internal assembly ring for assembling the valve stem installed inside the side-mounted glass observation window, and an external locking control head elastically assembled on the outer end of the valve stem.

[0005] The inner assembly ring has a polygonal limiting groove on its outer side surface, and the outer locking control head has a polygonal locking groove on its connecting surface that matches the polygonal limiting groove.

[0006] The outer end of the valve stem is axially fixed with an end limit head that cooperates with the external locking control head.

[0007] An internal compression spring is fitted on the outer side of the valve stem between the external locking control head and the end limit head.

[0008] The outer side of the side-mounted glass observation window is engraved with a ring scale around the inner assembly ring.

[0009] The side-mounted glass observation window can be a circular transparent observation window or a rectangular transparent observation window.

[0010] The beneficial effects of this utility model are:

[0011] (1) The valve of this utility model that allows observation of the internal mechanism status is provided with a side-mounted glass observation window on the side wall of the valve body. The glass material is pressure-resistant and corrosion-resistant and is sealed with the valve body, so that the operator can directly see the actual position of the control components and ensure that the valve scale is consistent with the internal mechanism status.

[0012] (2) By observing the internal status in an intuitive way, the pressure difference problem caused by valve opening deviation can be quickly identified, reducing the troubleshooting time and improving the efficiency of system acceptance. Attached Figure Description
