Abstract
An inswept anti wear eccentric rotary valve comprises a valve body, an upper shaft, a lower shaft, a rotary spool and a valve seat, wherein the valve seat is fixed on the valve body, the rotary spool is connected with the upper and lower shaft, the rotation of the upper shaft drives the rotation of the rotary spool and has on and off cooperation with the valve seat, the valve body inner wall and the spool block section appear inswept, two supporting arms of the rotary spool is equipped on the edge of a truncated sphere, and the valve body inner wall can be equipped with lining glue layer. According to the improvement, the utility model decreases the shocking effect on the valve body inner wall of the medium, increases the communication area of the valve body inner chamber for the convenient communication of the medium, which makes the utility model has a quite strong anti wear anti erosion function, effectively absorb the choking energy of hard mass point, and decreases the flushing effect on the valve body inner wall. The utility model has reasonable design and convenient using and can prolong the using life.
Description
(1) technical field
The utility model relates to a kind of valve, particularly a kind of streamlined wear-resisting camflex valve door.
(2) background technique
Be people's question of common concern the working life of valve all the time.Many production media of iron and steel, electric power, chemical industry are all gas, liquid and solid matter, and it is wherein in the majority with liquid and solid especially, in these media, contain a large amount of hard points and solid granular thing, under the effect of pressure and flow velocity, trim and valve body are produced strong souring, cause valve to be destroyed in a short time, produce the inconvenience that has brought very big cost pressure and used to enterprise.The immediate cause that causes the valve premature damage is nothing but that unreasonable structure, valve material wear no resistance.Circulation and protection against erosion that traditional camflex valve intracoelomic cavity structure, trim structural design are unfavorable for medium.As: valve shaft runs through valve body block media circulation passage; Spool, body cavity part-structure are unreasonable, make between body cavity and the medium and have formed direct corresponding contact, cause valve body, trim to be washed away and premature damage, influence working life.
(3) summary of the invention
At the defective of prior art, the utility model provides a kind of reasonable in design, easy to use and streamlined wear-resisting camflex valve door that can increase the service life.
A kind of streamlined wear-resisting camflex valve door is made up of valve body, valve shaft, rotary spool and valve seat, and valve seat is fixed on the valve body by the locking back-up ring; Rotary spool is connected on the valve shaft, and the rotation by valve shaft drives the rotary spool rotation, closes with valve seat to cooperate, and it is characterized in that valve shaft comprises spool (live axle) and a lower shaft (back shaft); Body cavity and rotary spool shelves mouth cross section are streamlined.
Two support arms of described rotary spool are positioned at the intercept sphere edge.
Described valve interior wall has the line with rubber layer.
Described line with rubber layer is made by rubber material.
The utility model has weakened the percussion of medium to body cavity and spool shelves mouth because body cavity and rotary spool shelves mouth cross section are carried out airflow design; The valve shaft that will run through body cavity changes axle (live axle) and lower shaft (back shaft) (see figure 1) into and two support arms of rotary spool is designed in intercept sphere edge (see figure 3), increased rotary spool shelves mouth aperture, compare with the correlation technique (see figure 4), the circulation area that has obviously increased body cavity makes medium be convenient to circulation; Make it have extremely strong antiwear anti-corrosion effect by the improvement that valve interior wall is had line with rubber layer (see figure 2), absorb the impact energy of hard point effectively, reduced souring valve interior wall.
The utility model is reasonable in design, and is easy to use and can prolong working life of valve.

(5) embodiment
Embodiment 1:
The utility model is made up of valve body 12, last axle (live axle) 7, lower shaft (back shaft) 13, rotary spool 10 and valve seat 9 as shown in Figure 1, and valve seat 9 is fixed on the valve body 12 by locking back-up ring 11; Rotary spool 10 is connected on axle 7 and the lower shaft 13, and the rotation by last axle (live axle) 7 drives rotary spool 10 rotations, closes with valve seat 9 to cooperate, and 10 grades of mouth cross sections of valve body 12 inwalls and rotary spool are streamlined; Two support arms 19 of rotary spool 10 are positioned at intercept sphere 18 edges.
Embodiment 2:
Present embodiment is as described in the embodiment 1, and different is that valve body 12 inwalls have line with rubber layer 17, as shown in Figure 2.
Claims (4)
1. a streamlined wear-resisting camflex valve door is made up of valve body, valve shaft, rotary spool and valve seat, and valve seat is fixed on the valve body by the locking back-up ring; Rotary spool is connected on the valve shaft, and the rotation by valve shaft drives the rotary spool rotation, closes with valve seat to cooperate, and it is characterized in that valve shaft comprises spool and lower shaft; Valve interior wall and spool shelves mouth cross section are streamlined.
