Abstract

The utility model relates to a novel knob butterfly valve which consists of a valve body (1), a valve rod (2), a gear shift knob (3) and the like and is characterized in that the valve body (1) adopts a through-type structure; a butterfly valve core (6) is positioned inside the valve body (1) and connected with the external gear shift knob (3) through the valve rod (2); and the butterfly valve core (6) is rotationally controlled by the gear shift knob (3) through the valve rod (2). A valve cover (4) and a valve seat (5) are tightly connected and combined on the valve body (1). The novel knob butterfly valve has the benefits that the structure is simple, the operation is convenient, and the flow rate can be effectively controlled; in addition, the novel knob butterfly valve is reliable in sealing performance and small in fluid resistance and is suitable for the pipeline application of viscous and granular matters; the knob directly drives the valve core through the valve rod, so that the control is more simple and convenient; meanwhile, the valve structure is simplified; through the arrangement of the shift knob, the flow rate can be changed according to the practical demands; and the operation is simple, the water is saved, and the environment is protected.

Description

The novel turn knob butterfly valve
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of novel turn knob butterfly valve.
Background technique
Valve is the device of the direction that in fluid system, is used for controlling fluid, pressure, flow.Valve is the device that pipe arrangement and the interior medium (liquid, gas, powder) of equipment is flowed or stop and controlling its flow.Valve is a controlling component in the pipeline fluid delivery system, and it is to be used for changing path section and media flow direction, has water conservancy diversion, by functions such as, throttling, non-return, shunting or overflow releases.The valve that is used for fluid control, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are various, the inside nominal diameter of valve is used valve to the industrial pipeline that latus rectum reaches 10m greatly from atomic little Gauge Valves.Valve can be used for controlling flowing of all kinds fluids such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid.Valve rely on to drive or automechanism makes open-shut device do up-down, slippage, swing or rotation motion, thereby the size that changes its Flow area is to realize its control function.The conventional valves complex structure, seal is poor, and is not easy to operate, can't accomplish to change flow by actual usage requirement.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provides a kind of novel turn knob butterfly valve, and it is simple in structure, and is easy to operate; Effectively control flow rate and environment-friendly water-saving; Be made up of valve body (1), valve rod (2), stepping knob (3), valve gap (4), valve seat (5), butterfly spool (6) dashpot (7), water inlet (8), water outlet (9), it is characterized in that valve body adopts through structure, the butterfly spool is positioned at the inside of valve body; The butterfly spool is connected with outside stepping knob through valve rod, and knob is through valve rod Spin Control spool.Valve gap is connected with valve seat combines closely on valve body.
The beneficial effect of the utility model is: sealing is reliable, and fluid resistance is little, is fit to thickness and contains the pipe applications of particulate material.Knob makes control more easy through the design that valve rod directly drives spool.Simplified valve mechanism simultaneously.The setting of stepping formula knob can make flow change immediately according to actual demand, and is simple to operate, water-saving and environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the spool part plan view of the utility model.
Embodiment
According to shown in Figure 1; Butterfly spool (6) is positioned at the inside of valve body (1); Butterfly spool (6) is connected with outside stepping knob (3) through valve rod (2), and stepping knob (3) can be divided into many grades of flow grades, and through controlling the Spin Control butterfly spool (6) of connected valve rod (2).Valve gap (4) is connected with valve seat (5) and combines closely on valve body (1).Valve rod (2) passes valve gap (4), valve seat (5) and is connected on stepping knob (3) and the butterfly spool (6) with valve body (1).

Claims (1)
