Abstract
The utility model discloses a kind of good valve mechanism of seal wear-resistant performance, include the valve body for cooperating and installing, valve rod, valve seat, valve element, valve pocket, divided ring is passed sequentially through from top to bottom between the valve rod and valve element and gland press-fits, and the positioning screw of gland upper end is compressed, multiple tracks groove is distributed with the outer circumference surface that the upper end of the valve element coordinates with valve pocket, wear ring and sealing ring are installed with the groove, and sealing ring is located at middle part, the bottom of the valve pocket is provided with axially position hole, orientation axes for blocking valve element top bar are installed in the positioning hole, and by positioning the screw in compression of shaft end.The utility model is simple in construction, reasonable in design, can enable valve element and the correct centering of valve pocket, and prevents foreign matter from entering O shape circles, and the wearability and sealing of valve element and valve pocket sealing surfaces are enhanced for this, the service life of product is extended.
Description
Technical field：
The utility model is related to a kind of valve, relates generally to a kind of good valve mechanism of seal wear-resistant performance.
Background technology：
During general valve assembling, valve seat is difficult to be fitted into the valve seat groove of valve body, and the runner hole of valve pocket and valve element is difficult to pair
In, influence throttle-flow.When valve controls flow under the operating mode of super-pressure, medium will wash away runner.If valve seat and valve element
Sealing surfaces sustain damage when needing detachable maintaining, and valve seat is not easy to remove and assembles, and the throttling stop valve of through type is in dismounting valve seat
During with valve pocket, the specific purpose tool for wanting special of still needing is not easy to repair and check on pipeline.
Utility model content：
The utility model purpose is exactly that there is provided a kind of good valve of seal wear-resistant performance in order to make up the defect of prior art
Structure.
The utility model is achieved through the following technical solutions：
A kind of good valve mechanism of seal wear-resistant performance, include cooperate install valve body, valve rod, valve seat, valve element,
Valve pocket, it is characterised in that：Divided ring is passed sequentially through from top to bottom between the valve rod and valve element and gland press-fits, and gland upper end
The positioning screw in portion is compressed, and the upper end of the valve element is described recessed with multiple tracks groove is distributed with the outer circumference surface of valve pocket cooperation
Wear ring and sealing ring are installed with groove, and sealing ring is located at middle part, the bottom of the valve pocket is provided with axially position hole, described
Orientation axes for blocking valve element top bar are installed in positioning hole, and by positioning the screw in compression of shaft end.
Described groove is four roads.
Its principle is by changing valvular valve rod and valve element, the fit structure between valve element and valve pocket, by increasing
Plus orientation axes and the structure of wear ring and divided ring, when can assemble valve, gland is first inserted in valve rod and is reloaded into after divided ring
Valve element is screwed into, with positioning screw is made, each wear ring and seal is installed, then valve seat is loaded into valve pocket, valve element is then loaded into valve
Set.Load orientation axes automatically to position runner direction, the part after installing together is loaded into valve body.
The utility model has the advantages that：
The utility model is simple in construction, reasonable in design, can enable valve element and the correct centering of valve pocket, and prevent foreign matter from entering O
Shape circle, the wearability and sealing of valve element and valve pocket sealing surfaces are enhanced for this, the service life of product is extended.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Referring to accompanying drawing.
A kind of good valve mechanism of seal wear-resistant performance, includes the cooperate valve body 1 installed, valve rod 2, valve seat, valve
Core 3, valve pocket 4, pass sequentially through divided ring 5 from top to bottom between valve rod 1 and valve element 3 and gland 6 press-fits, and the upper end of gland 6
Positioning screw compresses 7, and the upper end of valve element 3 is installed with being distributed with the outer circumference surface of the cooperation of valve pocket 4 in multiple tracks groove, groove
Wear ring 8 and sealing ring 9, and sealing ring 9 is located at middle part, the bottom of valve pocket 4 is provided with to install in axially position hole, positioning hole and used
In blocking the orientation axes 10 of valve element top bar, and pass through the screw in compression of the end of locating shaft 10.Described groove is four roads.
