Embodiment 1

[0019] Such as figure 1 , The present invention provides a discharge butterfly valve, comprising a valve seat 8, a valve core 9 located in the inner cavity of the valve seat 8, and a valve stem 5 fixedly connected to the valve core 9 at one end, and the free end of the valve stem 5 is located in the valve The outside of the seat 8 also includes a rod-shaped handle 1, a spring 3 and a slot seat 7. The free end of the valve stem 5 is provided with a strip groove, and the handle 1 is partially located in the strip groove, and the handle 1 and the valve stem 5 Through the hinged connection of the hinge nail 4 crossing the strip groove, the slot seat 7 is fixedly connected to the valve seat 8. The slot seat 7 is provided with a plurality of slot slots 6, and the handle 1 is partly located in any slot 6, so One end of the spring 3 is in contact with the handle 1 and is compressed between the valve seat 8 and the handle 1, and the hinge nail 4 is located between the spring 3 and the s...

Embodiment 2

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

Embodiment 3

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

[0025] In order to make the spring 3 rotate at the same angular velocity with the valve stem 5 and avoid excessive distortion 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 following block 2 is also provided with a blind hole, and the spring 3 is partially located in the blind hole.

[0027] The set follower block 2 is used to limit the rotation angle of the valve stem 5, and can ...

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] A powder mixer is generally used in the solid drug production process to uniformly mix the components of the drug. The powder mixer used in mass production completes the above mixing. Generally, each component of the drug is poured into a container through a stirring device Stir to achieve. The bottom of the container is generally provided with a material discharge valve. At the same time, based on the shape of the powder fluid and the rapid opening and closing requirements of the valve in production, the valve is mostly butterfly valve. In order to avoid oil pollution, the butterfly valve is mostly manual. Moving butterfly valve. [0003] In the prior art, the manual brake mechanism of butterfly valves is generally divided into two structural forms: worm and worm gear and rack handle. The brake mechanism of the rack handle...
