Abstract
The utility model discloses a throttling valve which comprises a handwheel, an adjusting assembly, a valve rod, an O-shaped seal ring, a sealing washer and a valve body. The throttling valve is characterized in that a cone part at the lower end of the valve rod is set into a ladder-shaped structure, the outer surface of the adjusting assembly is provided with screw threads, and the outer surface of the lower end of the handwheel is provided with scales for indicating the adjusted flow rate. The throttling valve has the characteristics of realization of two purposes of one valve, convenient control of the flow rate in adjustment as well as convenient installation and fixation.
Description
Technical field
The utility model relates to a kind of throttle valve, goes into F16K15/18.
Background technique
Throttle valve is a kind of skeleton symbol flow control valve, and it is to change the pressure that passage section is regulated flow or changed the valve front and back when utilizing flow by throttle valve.Existing throttle valve is clearance type mostly, leans on the cone structure of valve rod end to play on-off action, and function ratio is more single, and does not have the flow indication, brings inconvenience to the user.
The model utility content
The purpose of this utility model is to provide that a kind of to overcome existing throttle functionality single, the novel throttling valve of the defective of no flow indication.
The utility model is achieved in that a kind of throttle valve comprises handwheel, adjusting part, valve rod, O RunddichtringO, seal washer and valve body.Wherein, valve rod is contained in the inner chamber of adjusting part and is scyewed joint, conical section is arranged to stepped construction in the lower end of valve rod, between adjusting part lower end and valve body, seal washer is housed, in the adjusting part upper end handwheel is housed, the lower end outer surface of handwheel is provided with the scale that flow is regulated in indication, and the outer surface of adjusting part is provided with screw thread, is convenient to install and fix.The O RunddichtringO is contained in the seal groove on the valve rod.
The utility model compared with prior art its main feature is:
1, on the outer surface of adjusting part, is provided with screw thread, is convenient to install and fix;
2, the lower end outer surface of handwheel is provided with the scale that flow is regulated in indication, is convenient to control flow rate when throttle valve uses;
3, because valve rod lower end conical section is arranged to stepped construction, thereby throttle valve becomes stop valve when dead when handwheel closes, and it is throttle valve that handwheel does not close when dead, realizes that a valve is dual-purpose.
Description of drawings
Fig. 1, throttle valve structural representation of the present utility model.
Fig. 2, handwheel external form schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Throttle valve of the present utility model is as shown in Figure 1 and Figure 2: it comprises handwheel 1, adjusting part 2, valve rod 3, O RunddichtringO 4, seal washer 5 and valve body 6.Wherein, valve rod 3 is contained in the inner chamber of adjusting part 2 and is scyewed joint, conical section is arranged to stepped construction in the lower end of valve rod 3, seal washer 5 is housed between adjusting part lower end and valve body, in the adjusting part upper end handwheel 1 is housed, be provided with indication and regulate the scale of flow on the outer surface of the lower end of handwheel, the outer surface of adjusting part is provided with screw thread, and the O RunddichtringO is contained in the seal groove on the valve rod 3.The working principle of the utility model throttle valve is same as the prior art or similar.
