Abstract
The utility model provides a low torque ball valve, through respectively installing a slice cam disc in spheroid top and bottom, when the valve when closing and open, the little disk seat of cam outside diameter can be laminated on the spheroid, when the valve starts, cam outside diameter is the grow slowly, the disk seat breaks away from the spheroid when backing down the disk seat on both sides, like this frictional force has become, the friction of cam disc and disk seat, these two contact surfaces are little, frictional force is more a lot of than disk seat and spheroid small friction, via the structure, the moment of torsion diminishes when making the spheroid open, the switch is more convenient.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of low torque ball valve.
Background technique
Existing conventional ball valve, when its valve seat and spheroid are all fitting together, such structure make words ball valve open and close time cause switching torque excessive, need the frictional force simultaneously overcoming valve seat and spheroid, thus cause in the switching process of ball valve very inconvenient.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of low torque ball valve.
The technical solution that the utility model adopts is: a kind of low torque ball valve, comprise valve body, valve seat, valve rod and spheroid, filler is provided with between described valve body and valve rod, Gland is provided with above described filler, described Gland is arranged on valve body by bolt, the upper and lower two ends of described spheroid are equipped with cam disk, and described cam disk comprises the first state that spheroid and valve seat are fitted and the second state that spheroid and valve seat are departed from.
Described cam disk comprises normal disc, and described normal disc is provided with the convex portion being greater than normal disc diameter.
Be provided with mounting hole in the middle of described normal disc, described cam disk is set on spheroid by mounting hole.
Described cam disk is mounted by means of bolts on spheroid.
The beneficial effects of the utility model are: the utility model provides a kind of low torque ball valve, by respectively installing a slice cam disk in spheroid top and bottom, when valve is when closing and open, the little valve seat of cam outside diameter can be fitted on spheroid, when the valve is activated, cam outside diameter slowly becomes large, when the valve seat on both sides is backed down, valve seat departs from spheroid, like this frictional force becomes, the friction of cam disk and valve seat, these two surface of contact are little, frictional force than valve seat and sphere friction power much little, by such structure, when spheroid is opened, moment of torsion diminishes, switch is more convenient.

Embodiment
Existing composition graphs 1, Fig. 2, Fig. 3 are further described the utility model, a kind of low torque ball valve, comprise valve body 1, valve seat 2, valve rod 3 and spheroid 4, filler 5 is provided with between described valve body 1 and valve rod 3, Gland 51 is provided with above described filler 5, described filler 5 gland is arranged on valve body 1 by bolt, described spheroid about 4 two ends are equipped with cam disk 6, and described cam disk 6 comprises the first state that spheroid 4 and valve seat 2 are fitted and the second state that spheroid 4 and valve seat 2 are departed from.Described cam disk 6 comprises normal disc 61, and described normal disc 61 is provided with the convex portion 62 being greater than normal disc 61 diameter.Be provided with mounting hole 63 in the middle of described normal disc 61, described cam disk 6 is set on spheroid 4 by mounting hole 63.Described cam disk 6 is mounted by means of bolts on spheroid 4.The utility model is by respectively installing a slice cam disk 6 in spheroid 4 top and bottom, when valve is when closing and open, the little valve seat 2 of cam outside diameter can be fitted on spheroid 4, when the valve is activated, cam outside diameter slowly becomes large, when the valve seat 2 on both sides is backed down, valve seat departs from spheroid 4, like this frictional force becomes, the friction of cam disk 6 and valve seat 2, these two surface of contact are little, frictional force than valve seat 2 and ball 4 body frictional force much little, by such structure, when spheroid 4 is opened, moment of torsion diminishes, and switch is more convenient.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
