Abstract
The utility model discloses a flow control valve controlling maximum flow. The flow control valve controlling maximum flow comprises a handle (1), a valve rod (2), a valve cover (3), a valve body (4) and a seal ring (5), wherein a spacing baffle ring (6) limiting movements of the valve rod (2) is arranged on the valve rod (2) of the flow control valve; and when the spacing baffle ring (6) on the valve rod (2) contacts with the valve cover (3) via the flow control valve, a maximum gap is formed between a tapered body on the valve rod (2) and a round hole on the valve body (4), so an open degree of the flow control valve is maximum and flow of cleaning agent becomes maximum, thereby achieving a purpose of controlling the maximum flow.
Description
Technical field: the utility model relates to a kind of flow control valve of controlling peak rate of flow, is mainly used in automobile ternary/gas handling system cleaning equipment.
Background technique: existing automobile ternary/gas handling system cleaning equipment flow control valve used is not controlled the function of peak rate of flow, easily causes washing agent flow excessive, and motor car engine is caused damage.
Model utility content: the purpose of this utility model is to provide a kind of flow control valve to have the function of controlling peak rate of flow.Technical problem to be solved is: existing flow control valve is not controlled the function of peak rate of flow, and when adjust flux, flow control valve is easy to regulate excessive, makes the flow of washing agent excessive, and motor car engine is caused damage.
The technological scheme that the utility model technical solution problem adopts is as follows:
The spacing back-up ring that design restriction valve rod moves on the valve rod of flow control valve, it is the peak rate of flow of limited flow modulating valve, when adjust flux modulating valve makes spacing back-up ring on valve rod contact with valve gap, it is maximum that the aperture of flow control valve reaches, it is maximum that the flow of washing agent just reaches, and plays the function of controlling peak rate of flow.
Good effect of the present utility model is: the spacing back-up ring that design restriction valve rod moves on the valve rod of flow control valve, when adjust flux modulating valve makes spacing back-up ring on valve rod contact with valve gap, it is maximum that the aperture of flow control valve reaches, it is maximum that the flow of washing agent just reaches, and plays the function of controlling peak rate of flow.Can design as required the relative position of spacing back-up ring and valve gap, control required peak rate of flow, guarantee that the peak rate of flow of washing agent is no more than safe traffic, during to the cleaning of ternary and gas handling system, motor car engine be played to safety protection effect.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment: below in conjunction with accompanying drawing and embodiment is provided, the utility model is further described.
As shown in Figure 1, the utility model comprises handle 1, valve rod 2, valve gap 3, valve body 4, seal ring 5; It is characterized in that: at the mobile spacing back-up ring (6) of the upper design restriction valve rod of valve rod (2) (2), the external diameter of spacing back-up ring 6 is greater than the external diameter of the upper screw thread coordinating with valve gap (3) of valve rod (2), taper on valve rod (2) coordinates with the circular hole on valve body (4), the diameter of circular hole is less than the maximum diameter of taper, when taper be moved to the left until and while there is no gap between circular hole, valve cuts out, adjust flux modulating valve is moved to the left valve rod (2), change from small to big in the gap of taper and circular hole, flow also changes from small to big; When the spacing back-up ring (6) on valve rod (2) contacts with valve gap (3), the taper of valve rod (2) becomes maximal clearance with the circular hole on valve body (4), now the aperture of flow control valve is maximum, and it is maximum that flow also reaches, thereby realizes the object of restriction washing agent flow.
Claims (1)
1. a flow control valve of controlling peak rate of flow, it is characterized in that: at the mobile spacing back-up ring (6) of the upper design restriction valve rod of valve rod (2) (2), the external diameter of spacing back-up ring (6) is greater than the external diameter of the upper screw thread coordinating with valve gap (3) of valve rod (2), taper on valve rod (2) coordinates with the circular hole on valve body (4), the diameter of circular hole is less than the maximum diameter of taper, when taper be moved to the left until and while there is no gap between circular hole, valve cuts out, adjust flux modulating valve is moved to the left valve rod (2), change from small to big in the gap of taper and circular hole, flow also changes from small to big, when the spacing back-up ring (6) on valve rod (2) contacts with valve gap (3), the taper of valve rod (2) becomes maximal clearance with the circular hole on valve body (4), now the aperture of flow control valve is maximum, and it is maximum that flow also reaches, thereby realizes the object of restriction washing agent flow.
