Abstract

The invention provides an angular travel adjusting valve, which comprises a first valve channel, a second valve channel, a valve rod, a valve element and a valve seat. The valve rod and the valve element are arranged in the valve seat, by rotating the valve rod, the valve element can be driven to rotate, the first valve channel communicates with a flow-guiding groove in the valve rod, the flow-guiding groove communicates with the second valve channel through a flow channel hole in the valve element, thus the angular travel adjusting valve is opened, by revolving the valve rod, the angular travel adjusting valve can be closed, the plane, close to the second valve channel, of the valve element serves as a sealing face to plug the second valve channel or communicate with the second valve channel, the phenomenon of unbalance loading of the valve rod or switch tripping is avoided, the applicability and compatibility of the travel adjusting valve are improved, and manufacturing, using and popularizing are convenient.

Description

technical field [0001] The invention relates to the field of valve manufacturing, in particular to an angular stroke regulating valve. Background technique [0002] In the existing valve technology, the scope of application of control valves is more and more extensive. Generally, conventional control valves have good adaptability under the condition of lower medium pressure difference, but in the case of higher medium pressure difference The lower sealing performance and reliability are not ideal enough. Under the condition of high medium pressure difference, the eccentric load of the valve stem of the straight-stroke regulating valve is relatively large, so it is necessary to improve the sealing level of the valve to meet the use requirements. Improving the sealing level of the valve not only needs to increase the diameter of the valve stem, but also the valve required The output power of the actuator is also large, the overall structure of the valve is heavy, and it is co...
