Problems solved by technology

[0002] At present, there are relatively large defects in the structure of the control of the valve body, so that the control of the valve body is all in one step, and it cannot effectively control the multi-stage closing and opening of the valve body.
Moreover, after the valve body is controlled to open the valve, the reset of the entire mechanism for controlling the opening and closing of the valve has a relatively large defect, which cannot be effectively reset, thereby affecting the next opening and closing of the valve.

Embodiment Construction

[0009] Combine below figure 1 with figure 2 Specific description embodiment:

[0010] The step-by-step automatic reset mechanism includes a bracket 4 and a graded switch bar 7. The graded switch bar includes a first-level switch bar 8, a second-level switch bar 9, a third-level switch bar 10 and a substrate 11. The first-level switch bar and the second-level switch bar The first-level switch bar is hingedly arranged, the second-level switch bar is hingedly arranged with the third-level switch bar, and the third-level switch bar is hingedly arranged with the base plate. Bar slot 12, the other side of the second-level switch bar, the third-level switch bar and the substrate are each provided with a reset hole 13, and the reset hole communicates with the bar slot; the support is provided with a reset lever corresponding to the reset hole 17. When the substrate is reset, the reset rod hits the third-level switch bar, the second-level switch bar and the first-level switch bar in...

Abstract

The invention belongs to the technical field of automatic valve tools, and particularly relates to a step-by-step type automatic reset mechanism. The step-by-step type automatic reset mechanism comprises a bracket and a grading switch bar, wherein the grading switch bar comprises a first-stage switch bar, a second-stage switch bar, a third-stage switch bar and a substrate. The bracket is providedwith reset rods corresponding to reset holes, and when the substrate is reset, the reset rods pass through the reset holes and then impact the third-stage switch bar, the second-stage switch bar and the first-stage switch bar in bar grooves, so that the third-stage switch bar, the second-stage switch bar and the first-stage switch bar are reset. The step-by-step type automatic reset mechanism hasthe beneficial effects that a valve of a valve body can be hierarchically controlled, the degree of opening of the valve can be effectively controlled, a valve opening device after the hierarchical control can be effectively reset, and the reset is accurate and orderly.

Description

technical field [0001] The invention belongs to the technical field of automatic valve appliances, in particular to a step-by-step automatic reset mechanism. Background technique [0002] At present, there are relatively large defects in the structure of the control of the valve body, so that the control of the valve body is all in one step, and the multi-stage closing and opening of the valve body cannot be effectively controlled. Moreover, after the valve body is controlled to open the valve, the reset of the whole control valve opening and closing mechanism has a relatively large defect, which cannot be effectively reset, thereby affecting the next opening and closing of the valve. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems described above, to provide a valve that can control the valve of the valve body in stages, can effectively control the degree of opening of the valve, and can effectively reset the valv...
