Description
Technical field
The utility model relates to a kind of fuel gas plug valve.
Background technique
Stopcock in gas range is the manual operating valve controlling source of the gas supply.Common stopcock generally comprises the valve body having gas-entered passageway and outlet passageway, revolvable spool is provided with in valve body, spool top has spring chamber, spool bottom is provided with venting cavity, valve body is equipped with the valve rod that can drive Spool rotating, the lower end of valve rod holds and makes valve rod keep moving and departing from the spring being connected trend with spool, and spring is positioned at the spring chamber on spool, the venting cavity sidewall of spool has the large fire hole and the small fire hole that are communicated with gas-entered passageway and outlet passageway.During use, user is by being arranged on knob on operation panel and operating valve lever, general first pressing knob also rotates counterclockwise, movable valve plug can be with to rotate counterclockwise, large fire hole on spool is connected with the gas-entered passageway in valve body, now, source of the gas can spray, for gas utensil from nozzle through gas-entered passageway, greatly fire hole, venting cavity and outlet passageway.When turning the intensity of a fire down, user continues to rotate counterclockwise knob, and the small fire hole on spool is connected with the gas-entered passageway in valve body, reduces the circulation passage of source of the gas and reaches the object reducing the intensity of a fire.If user wants the little intensity of a fire to remap to the maximum intensity of a fire, also, rotary valve key, spool to be communicated with the gas-entered passageway in valve body from its small fire hole and is converted into its large fire hole and communicates with the gas-entered passageway in valve body.
A kind of gas valve as disclosed in the patent No. Chinese utility model patent " fuel gas plug valve " that is ZL201020181562.8 (notification number is CN201672087U).
In existing this stopcock, valve rod is when regulating intensity of a fire size, and the rotation of valve rod does not all have damping, and valve rod can by driven rotary very like a cork, and feel is poor, easily excessive or not in place when valve rod rotates, thus when causing regulating the intensity of a fire, is difficult to precisely control intensity of a fire size.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of valve rod in rotary course, have the fuel gas plug valve of certain damping for above-mentioned prior art present situation, this stopcock has valve rod and rotates good hand touch, and more precisely can manipulate the advantage of valve rod angle of swing.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of fuel gas plug valve, comprise valve body, spool and valve rod, the end winding support of valve body has valve gap, spool is located in valve body, valve rod is connected to drive Spool rotating through after valve gap with spool, is also provided with and acts on valve rod with the spring making valve rod keep trend of moving in valve body; It is characterized in that: described valve rod is fixed with contact component, this contact component keeps contacting with the inner top surface of valve gap under the effect of described spring, concave-convex fit structure is provided with between the end face that the inner top surface of contact component and valve gap contacts with each other, recessed in concave-convex fit structure is the spaced apart hole of multiple circumference or groove, and convex in concave-convex fit structure is salient point or convex tendon.
Above described holes or groove are arranged on contact component, and described salient point is then arranged on the inner top surface place of valve gap.The position of certain hole or groove and salient point can exchange.
Ringwise, described hole or groove circumferentially uniform intervals are arranged above-mentioned contact component.Because the angle of swing of valve rod when regulating the intensity of a fire is less than 360 °, therefore contact component is curved also can meet the demands, just to there is difference that orientation is set for dissimilar stopcock to contact component relative to the position of valve rod like this, but as contact component is arranged ringwise, the so no matter stopcock of which kind of type, can ensure in valve rod rotary course, salient point can with hole or slot fit effect.
Above-mentioned salient point or convex tendon have multiple.Multiple salient point or convex tendon with hole or coordinating of groove damping sense can be made larger, feel during rotary valve rod is better.
Together with above-mentioned contact component is molded over valve-stem integrated.Certain contact component and valve rod also can split productions.
The inner top surface place of above-mentioned valve gap is fixed with pad, and described salient point is arranged on this pad.Because salient point will rub with hole or flute length time, and valve gap generally adopts aluminium cast iron manufacture to form, its wear resistance is poor, and as being set directly on the inner top surface of valve gap by salient point, the long-time salient point that uses is easy to wear, in addition valve gap is arranged salient point also inconvenient, salient point is arranged on pad by this structure, and such pad can adopt the metal manufacture of other wear-resistant material, and salient point also can directly punching press be out in addition, easily manufactured, pad and valve gap need be fixed for last.
Above-mentioned salient point has three and is uniformly distributed along the circumference.
Compared with prior art, the utility model has the advantage of: under the action of the spring, coordinated with the conflict of hole or groove by salient point or convex tendon between contact component and the inner top surface of valve gap, form certain damping to valve rod in rotary course, the operating handle of user is better; The conflict of salient point and hole or groove coordinates and can make valve rod in rotary course in addition, has the instruction sound of whip, judges the angle that valve rod rotates, can more precisely manipulate valve rod angle of swing according to the large activation of number of times that instruction sound sends; Realize aforementioned object and additionally increase parts hardly, and make full use of original valve inner space, the basis being adapted at original stopcock is transformed.
