Abstract
The utility model relates to an adjusting valve, which is provided with a valve body, wherein a valve rod is arranged in an inner cavity of the valve body; a valve plug is connected with the bottom end part of the valve rod; a sleeve is sleeved at the external part of the valve plug; an annular bulge is arranged at the bottom end of the sleeve; the annular bulge of the sleeve is hermetically connected with the valve body; a bulge on the inner wall at the middle part of the sleeve is engaged with the bulge on the outer wall of the valve plug; the bulge on the outer wall at the upper end of the sleeve is hermetically connected with the valve body; the annular bulge of the sleeve is hermetically connected with the valve body through a spiral washer; the bulge on the outer wall at the upper end of the sleeve is hermetically connected with the valve through a sawtoothed washer; and a wedge-shaped part is arranged at the upper part of the sleeve. As the sleeve for guiding is arranged on the valve rod, the upper and the rear ends of the sleeve are provided with the bulges which are hermetically connected with the valve body, the upper part of the sleeve is provided with the wedge-shaped part, and the sleeve is engaged with the valve plug through the bulge, a satisfactory guiding function can be achieved for the valve rod, a double-seat adjusting valve can be manufactured, the valve is stable to operate, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of modulating valve.
Background technique
Conventional modulating valve is single-seat adjusting valve, has no guiding device on the valve rod, so stable inadequately during stem movement, and valve is little working life.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of modulating valve is provided, valve rod is stable, the valve long service life.
The utility model solves the technological scheme that its technical problem adopted: a kind of modulating valve, have valve body, and body cavity has valve rod; End, valve rod bottom is connected with valve plug; The valve plug outer cover is connected to sleeve, and described sleeve bottom has annular protrusion, and the annular protrusion of sleeve is connected with valve seal; The protruding interlock of the protruding outer wall with valve plug of the inwall at described sleeve middle part, the outer wall of described sleeve upper end is protruding to be connected with valve seal.
Further, the annular protrusion of sleeve and valve body are tightly connected through screw washer.
Further, the outer wall of sleeve upper end is protruding is tightly connected through serrated lock washer with valve body.
Further, described upper cartridge has wedge-like portion.
The beneficial effect of the utility model is: the sleeve of the utility model through on valve rod, being provided for leading; The sleeve upper and lower end all has convexity to be connected with valve seal, and upper cartridge has wedge-like portion, and sleeve and valve plug are also through protruding interlock; Can play leading role preferably to valve rod; Can be made into the two-seat version modulating valve simultaneously, valve rod is stable, has prolonged the working life of valve.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the partial structurtes schematic representation of the utility model;
Wherein: 1. valve body, 2. valve rod, 3. valve plug, 4. sleeve, 5. screw washer, 6. serrated lock washer.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Like the described a kind of modulating valve of Fig. 1, have valve body 1, valve body 1 inner chamber has valve rod 2; End, valve rod 2 bottom is connected with valve plug 3; Valve plug 3 outer cover are connected to sleeve 4, and sleeve 4 bottoms have annular protrusion, and the annular protrusion of sleeve 4 and valve body 1 are tightly connected through screw washer 5; The protruding interlock of the protruding outer wall with valve plug 3 of the inwall at sleeve 4 middle parts, the protruding joint with valve body 1 of the outer wall of sleeve 4 upper ends is tightly connected through serrated lock washer 6.
The sleeve 4 of the utility model through on valve rod 2, being provided for leading; Sleeve 4 upper and lower end all have protruding and valve body 1 is tightly connected, and sleeve 4 tops have wedge-like portion, and sleeve 4 and valve plug 3 are also through protruding interlock; Can be to 2 leading roles preferably of valve rod; Can be made into the two-seat version modulating valve simultaneously, valve rod 2 is stable, has prolonged the working life of valve.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
