The utility model provides a modified star-shaped cinder valve. The modified star-shaped cinder valve comprises a shell, an impeller, a driving motor, a baffle assembly and a plugging assembly. The impeller is arranged in an inner cavity of the shell and comprises a rotating shaft and a plurality of blades, the driving motor is in transmission connection with the impeller, the baffle assembly comprises two baffles fixedly connected in a feeding port of the shell, an inlet is formed between the two baffles, and the plugging assembly comprises a sealing plate connected between the outer ends of every two adjacent blades. The two partition plates are connected to the outer side of each sealing plate, a material receiving groove is formed between the two partition plates, and the material receiving grooves sequentially pass through the position below the inlet along with rotation of the impeller; the baffle assembly can reduce entering of materials, the blocking assembly can reduce the conveying amount of the materials, and therefore the requirement for the small conveying amount of the materials is met, and the motor frequency does not need to be reduced.

The utility model discloses a kind of test equipment for pneumatic control valve or actuator in the field of pneumatic actuator detection, including valve displacement measuring instrument and control cabinet;Control cabinet is delivered to pneumatic control valve or actuator and measures the pressure of compressed air, valve displacement measuring instrument measures the displacement of pneumatic control valve or actuator;The controller of control cabinet transmits pressure and displacement data to PC host computer by Ethernet, and PC host computer generates the detection report of pneumatic control valve or actuator.The utility model can improve the detection quality and efficiency of pneumatic actuator, improve the production efficiency of pneumatic actuator production enterprise, meet the increasing delivery requirement, solve the problem of low efficiency of factory inspection, stroke etc. rely on visual inspection, realize the digitization and intelligentization of production final inspection.

The utility model discloses a kind of sealing structure for carrier roller, including seal cover and end cap, seal cover and end cap are all set as circular disc body structure, and the outer diameter of end cap is greater than the outer diameter of seal cover, axial through hole one is equipped in the center of seal cover, and axial through hole two is equipped in the center of end cap, seal cover rear end surface is equipped with boss surface one, and first sealing portion is equipped in boss surface one;While end cap front end surface is equipped with boss surface two, and second sealing portion is equipped in boss surface two, seal cover and end cap are mutually inserted and buckled between first sealing portion and second sealing portion, form intercalation labyrinth type sealing connection structure.Using the sealing structure in the utility model, through the cooperation of seal cover, end cap and dust cover, the assembly process is simplified, effectively solve carrier roller end portion water seepage and dust problem, improve the service life of carrier roller, to meet the conveying requirement of belt conveyor, its overall structure is simple, reasonable in design, suitable for popularization and application.
