Detailed Description

Referring to fig. 1, a small-flow turbine flowmeter includes a flowmeter body 1, a connection port 11 is flanged on both sides of the flowmeter body 1, a plate frame 12 is slidably sleeved in the connection port 11, a filter screen 13 is fixedly embedded in the plate frame 12, a support plate 14 is fixed on the connection port 11, a winding post 15 is fixed on the support plate 14, a tightening cap 16 covers the winding post 15, and two symmetrically distributed through wire notches 17 are formed in the tightening cap 16.

Referring to fig. 1 and 2, a handle 2 is fixed to the tightening cap 16, and the tightening cap 16 is pulled to be disengaged from the winding post 15.

Referring to fig. 1 and 3, a limiting block 3 is fixed on the inner wall of the mouthpiece 11, and the plate frame 12 is disposed in contact with the limiting block 3, so as to limit and position the position of the filter screen 13.

Referring to fig. 1 and 3, the upper and lower sides of the plate frame 12 are provided with symmetrically distributed fork slots 4, a fork block 41 is slidably sleeved in the fork slots 4, the fork block 41 is connected with the fork slots 4 through a spring 42, and a shift pin 43 is fixed on the fork block 41 to ensure the stability of the telescopic reset of the fork block 41.

Referring to fig. 1 and 3, the slot 44 is disposed on the mouthpiece 11, and the pin 43 is inserted into the slot 44, so that the plate frame 12 can be conveniently taken out, and the filter screen 13 can be more conveniently cleaned.
