Abstract
A non-abrasion gas channel switching valve is composed of handle, valve rod connected to handle, valve body with conic gas holes, conic sealing rings matched with said gas hole, end cover, and valve rod locator in the valve body. Pulling handle can shift valve rod to switch the position of sealing ring relative to the gas holes, so changing the direction of gas flowing. Its advantages are no relative slide between sealing ring and gas hole surface, short stroke of sealing ring and valve rod, low friction and resistance, and long service life.
Description
Technical field:
The present invention relates to a kind of valve, especially a kind of valve that is used for gas circuit, particularly a kind of abrasion-less gas channel switchover valve.
Background technique:
In the prior art, air valve is widely used in all kinds of automation equipments, and air valve comprises seal ring, valve rod and be provided with the valve body of pore that in the motion switch of air valve, seal ring will slip over whole pore, has sliding friction between seal ring and valve body or valve rod.
Summary of the invention:
Technical problem to be solved by this invention is: because air valve of the prior art comprises seal ring, valve rod and be provided with the valve body of pore that in the motion switch of air valve, seal ring will slip over whole pore, has sliding friction between seal ring and valve body or valve rod.Cause ring wear fast, and the resistance of the push-and-pull of valve rod is big, so the life-span of air valve is shorter.The present invention solves the problems of the technologies described above the technological scheme that is adopted to provide a kind of abrasion-less gas channel switchover valve, described this abrasion-less gas channel switchover valve comprises handle, valve rod, valve body, seal ring, end cap and valve rod positioning device, wherein, described handle links to each other with valve rod, described valve rod is arranged in the described valve body, described seal ring is arranged on the described valve rod, described valve body is provided with pore, the opening of pore in the valve body inboard is coniform, described seal ring is coniform, its cone angle cooperates with the opening of valve body inboard, the maximum diameter of the inboard opening of described valve body in described valve body, also is provided with described positioning device greater than the thickness of described seal ring, described positioning device comprises a spring and a location spheroid, be provided with locating slot on described valve rod, when stem movement, the location spheroid slips in the locating slot, valve rod can be located, described end cap is arranged on two ends of valve body.Working procedure of the present invention is: the pulling handle makes the valve rod displacement, the inboard air vent openings of one side outer rim of seal ring and valve body place conical surface pushes contact mutually and plays the effect of sealing, seal ring is in the inboard air vent openings of valve body place switching position, thus the direction of change gas circuit.Air valve in the present invention and the prior art contrasts, because there is not relative slip between the seal ring of described air valve and the air vent wall, seal ring and valve rod travel are short, and it is little to rub, and the resistance of push-and-pull valve rod is little, so the air valve life-span is long.
Description of drawings:
Fig. 1 is the structural representation of a kind of abrasion-less gas channel switchover valve of the present invention.
Embodiment:
As shown in Figure 1, a kind of abrasion-less gas channel switchover valve of the present invention, comprise handle 1, valve rod 2, valve body 3, seal ring 4, end cap 5 and valve rod positioning device 6, wherein, described handle 1 links to each other with valve rod 2, described valve rod 2 is arranged in the described valve body 3, described seal ring 4 is arranged on the described valve rod 2, described valve body 3 is provided with pore 7, pore 7 is coniform at the opening of valve body 3 inboards, the both sides of described seal ring 4 are coniform, and its cone angle cooperates with the opening of valve body 2 inboards, and the maximum diameter of described valve body 2 inboard openings is greater than the thickness of described seal ring 4, in described valve body 2, also be provided with described valve rod positioning device 6, described valve rod positioning device 6 comprises a spring 8 and a location spheroid 9, is provided with locating slot 10 on described valve rod 3, when valve rod 3 motions, location spheroid 9 slips in the locating slot 10, can be with valve rod 3 location, and described end cap 5 is arranged on the two ends of valve body 2.Working procedure of the present invention is: pulling handle 1 makes valve rod 2 displacements, one side outer rim of seal ring 4 and valve body 3 inboard pore 7 opening conical surfaces push contact mutually and play the effect of sealing, seal ring 4 is in valve body 2 inboard pore 7 opening switching positions, thus the direction of change gas circuit.
Claims (2)
