Abstract

The invention discloses a detection device for a polyethylene ball valve and relates to the technical field of valve detection. The device at least comprises a base, a torque sensor and a motor, wherein the base comprises an upper bottom plate and a lower bottom plate; the torque sensor is disposed between the upper bottom plate and the lower bottom plate; the central axis of the torque sensor islongitudinal, the lower end of the torque sensor is driven to rotate by the motor and a valve rod connecting block is fixed at the upper end of the torque sensor; the top part of the valve rod connecting block is provided with a strip groove which can be engaged with the valve rod of a ball valve; the upper surface of the upper bottom plate is provided with a ball valve positioning mechanism whichcomprises a left positioning seat and a right positioning seat; the left positioning seat is provided with a left positioning bayonet for positioning a left connection pipe of ball valve and the right positioning seat is provided with a right positioning bayonet for positioning a right connection pipe of the ball valve. In order to solve a problem of low accuracy of direct detection of the polyethylene ball valve with a torque wrench directly in the prior art, the invention provides the polyethylene ball valve detection device with high accuracy and convenient operation.

Description

technical field [0001] The invention relates to the technical field of valve detection, in particular to a detection device for a polyethylene ball valve. Background technique [0002] In the existing natural gas pipeline network, metal ball valves have been gradually replaced by polyethylene ball valves. Polyethylene ball valves have the advantages of light weight, corrosion resistance, long life, etc., and are also convenient for construction and maintenance. [0003] As the opening and closing switch in the natural gas pipeline network, the natural gas ball valve needs to pass the torque test and air tightness test before leaving the factory. The existing torque test is often directly tested with a torque wrench. This torque test method has low precision and the data cannot be saved; the existing ball valve leak detection equipment often uses force-applying devices such as cylinders and jacks to clamp both ends of the ball valve. Fill the inner cavity of the ball valve w...
