Abstract

The invention discloses a large-size center line-type butterfly valve clack watertightness measurement equipment which comprises a support frame, a cavity tray, an upper cover, a water inlet pipe, a water outlet pipe and a hydraulic pressure gauge, wherein the support frame is used for supporting the cavity tray; the cavity tray has a fixed edge, and the fixed edge is provided with a cavity tray fixing hole; the upper cover is in a ring shape, the inner diameter of the upper cover is the same as the diameter of a valve clack in size, the upper end surface of the upper cover is uniformly provided with an upper cover fixing hole around a periphery. According to the large-size center line-type butterfly valve clack watertightness measurement equipment, the convenience for use is achieved, and extra training is unnecessarily carried out on an operator, so that the production cost can not be increased; simple structure and the convenience for manufacture are achieved, the popularization and application on industry are facilitated; the upper cover and the tray are fixed through a fixed bolt, so that the measurement effect is good; extra upper cover fixing equipment is unnecessarily used, so that the investment cost of the equipment is saved.

Description

technical field [0001] The invention belongs to the technical field of centerline butterfly valve processing, and in particular relates to a large-scale centerline butterfly valve flap watertightness measuring device. Background technique [0002] The centerline butterfly valve is a component used to realize the on-off and flow control of the pipeline system, and has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. The structural feature of the centerline butterfly valve is that the axis of the shaft, the center of the butterfly plate, and the center of the body are at the same position. [0003] The watertightness test of the valve disc is a process in the processing of the centerline butterfly valve. Due to the large size and weight of the large centerline butterfly valve, the existing disc watertightness testing equipment cannot be used for the large centerline butterfly valve. Therefore, how to effectively measure the wa...
