Embodiment 1

[0047] The valve actuating device of this embodiment includes: a valve actuating member 4 and a follower connecting rod.

[0048] The valve actuator 4 is operatively engaged with the first end of the follower link, the valve stop 4 and the first end of the follower link are fixed at least circumferentially therebetween, upon application of the valve stop 4, The valve stopper 4 rotates around the axis of the follower link, and the valve stopper 4 transmits the received rotational torque to the first end of the follower link.

[0049] The second end of the follower link is operatively engaged with the spool 5 of the valve, and the second end of the follower link and the spool 5 are at least circumferentially fixed. When the rotating torque acts, the follower connecting rod rotates around its own axis, and the follower connecting rod transmits the received rotating torque from the valve braking member 4 to the valve core 5 of the valve.

[0050] The operative engagement of the s...

Embodiment 2

[0074] The difference between the valve braking device of this embodiment and the valve braking device of Embodiment 1 is that the intermediate rod 3 is not integrally formed, but assembled by at least two or more intermediate rod elements extending along the same straight line .

[0075] Specifically, the intermediate rod 3 is composed of at least two or more intermediate rod elements extending along the same straight line, wherein adjacent intermediate rod elements are at least circumferentially fixed. The end surface of one intermediate rod element corresponding to the adjacent other intermediate rod element respectively includes a shape-matched fitting structure.

[0076] When the intermediate rod 3 is composed of two or more intermediate rod elements, the two ends of each intermediate rod element respectively include a first matching structure and a second matching structure, so that using the first matching structure and the second matching The fit of the structures is ...

Embodiment 3

[0079] The difference between the valve brake device in this embodiment and the valve brake device in Embodiment 1 is only that the connection mode between the middle rod 3 and the first rod 1 and the second rod 2 is different.

[0080] Specifically, the middle rod 3 forms an annular hole, the second end of the first rod 1 forms a circular shaft and is provided with a radial hole, and the second end of the first rod 1 connects with the screw passing through the radial hole. At least one wall of the middle rod 3 is connected, the first end of the second rod 2 forms a circular shaft and is provided with a radial hole, and the first end of the second rod 2 is connected to the middle rod by a screw passing through the radial hole. At least one wall of part 3 is connected.

[0081] When the middle rod 3 is a ring hole, the second end of the first rod 1 and the first end of the second rod 2 that cooperate with it form a cylinder, or at least form an outer cylindrical surface, and th...

Abstract

The invention relates to the technical field of drainage equipment, in particular to a valve braking device and drainage equipment. The valve braking device comprises a valve actuating part, the valveactuating part is in operable connection with a first end of a follow-up connecting rod, and a second end of the follow-up connecting rod is in operable connection with a valve element of a valve; the follow-up connecting rod comprises a first rod piece, a second rod piece and a middle rod piece, the middle rod piece is connected between the first rod piece and the second rod piece, the middle rod piece and the first rod piece and the second rod piece extend along the same straight line and are at least fixed in the circumferential direction of the straight line; and the drainage equipment comprises the valve and the valve braking device. According to the valve braking device and the drainage equipment, a connecting rod does not need to be specially customized, so that the valve actuatingpart of the drainage equipment can be installed according to the installation position requirement, therefore, the production cost is reduced, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a valve braking device and drainage equipment. Background technique [0002] Drainage equipment, as an important water conservancy equipment, is widely used in various industries, for example, it is used for drainage of condensed water in steam cabinets. [0003] During the use of the steamer, the food is steamed by the high temperature of the water vapor, but when the water vapor encounters an object with a relatively low temperature, the water vapor will generate condensed water. During the use of the steam cabinet, the generation of condensed water is unavoidable, so the steam cabinet is equipped with drainage equipment for draining condensed water. [0004] The drainage equipment on the steamer includes a valve arranged on the drain pipeline. When the valve actuator (valve handle) is operated, the valve is opened, and the condensed water is discharged from the dra...
