Embodiment 2

[0022] This embodiment is further limited on the basis of embodiment 1: as figure 1 , also includes a follower block 2 fixed on the valve stem 5, and the side of the free end of the card slot seat 7 is also provided with an arc whose arc length is within the range of one-third to one-half of the circumference of the card slot seat 7 The gaps and slots 6 are evenly distributed in the area other than the arc-shaped gaps on the free end, and the follower block 2 is located in the arc-shaped gaps. The above setting is convenient to set the card slot 6 along the circumferential direction of the card slot seat 7 at the end of the card slot seat 7. When the number of the card slots 6 is equal, the card slot seat 7 of the above structural form is compared with other structural forms. It has the characteristics of small size.

Embodiment 3

[0024] The present embodiment is further limited on the basis of embodiment 2: as figure 1 , also includes a follower block 2 fixed on the valve stem 5, and the side of the free end of the card slot seat 7 is also provided with an arc whose arc length is within the range of one-third to one-half of the circumference of the card slot seat 7 The gaps and slots 6 are evenly distributed in the area other than the arc-shaped gaps on the free end, and the follower block 2 is located in the arc-shaped gaps.

[0025] In order to make the spring 3 rotate with the same angular velocity of the valve stem 5 and avoid excessive twisting of the spring 3 when adjusting the opening of the butterfly valve, the two ends of the spring 3 are in contact with the follower block 2 and the handle 1 respectively.

[0026] The follower block 2 is also provided with a blind hole, and the spring 3 is partly located in the blind hole.

[0027] The set follower block 2 is used to limit the rotation angle ...

Abstract

The invention discloses a discharging butterfly valve. The discharging butterfly valve comprises a valve seat, a valve element located in an inner cavity of the valve seat and a valve rod of which one end is fixedly connected with the valve element and further comprises a rod-shaped handle, a spring and a clamping groove seat. The free end of the valve rod is located outside the valve seat. The end of the free end of the valve rod is provided with a bar-shaped groove, the handle is partially located in the bar-shaped groove, and the handle and the valve rod are hinged together through a hinging nail transversely penetrating through the bar-shaped groove. The clamping groove seat is fixedly connected to the valve seat and provided with a plurality of clamping grooves. The handle is partially located in any clamping groove. One end of the spring makes contact with the handle and is compressed between the valve seat and the handle. The hinging nail is located between the spring and the clamping grooves. The discharging butterfly valve is simple in structure, easy to manufacture and convenient to operate and clean and can meet requirements for cleaning regions around a discharge port of a powder mixing machine.

Description

technical field [0001] The invention relates to a powder medicine discharge valve, in particular to a discharge butterfly valve. Background technique [0002] In the production process of solid drugs, a powder mixer is generally used to uniformly mix the components of the drug. The powder mixer used in mass production completes the above mixing. Generally, the components of the drug are put into the container and passed through the stirring device. Stirring is achieved. The bottom of the above-mentioned container is generally provided with a material discharge valve. At the same time, based on the shape of the powder fluid and the requirement for the opening and closing of the above-mentioned valve quickly during production, the above-mentioned valve is mostly a butterfly valve. In order to avoid oil pollution, the above-mentioned butterfly valve is mostly manual. Butterfly valve. [0003] The manual braking mechanism of butterfly valves in the prior art is generally divid...
