Abstract
The utility model discloses an eccentric-type electric ball valve, which comprises a valve cover, a valve body, a supporting shaft jacket, a supporting shaft, an eccentric ball, a valve rod, an O-ring, a reducer and an electric motor, wherein, the reducer is connected with the valve rod, the head part of the valve rod which is of a geometrical shape is matched with an eccentric hole arranged on the upper part of the eccentric ball, so that the valve rod can drive the eccentric ball to rotate so as to form a structure that the spherical surface of the eccentric ball moves along the valve rod in the way of a cam when the valve is opened or closed,; the lower end of the eccentric ball is supported for positioning by the supporting shaft, and a sealing seat and a sealing ring, regulating the pressing force, are arranged between the valve body and the eccentric ball. The ball body of the eccentric-type electric ball valve is an eccentric ball body, so the ball body is free from contacting with the sealing ring most of the time during the rotating motion, thereby reducing the friction, reducing the rotation torque, reducing the power consumption and saving the energy; since the contact between the ball body and the sealing ring becomes less, the abrasion of the sealing ring is less, thereby greatly improving the service life of the valve.
Description
Technical field
The utility model belongs to valve technology field, a kind of valve of controlling automatically by the electronic equipment realization, particularly a kind of eccentric electric ball valve.
Background technique
In intelligent instrument (as water meter, gas meter etc.) industry, existing electric ball valve mostly is the electric ball valve that spheroid and seal ring are adjacent to.In this electric ball valve switch valve process, spheroid contacts all the time with seal ring, in Environmental Conditions, because the influence of medium causes the frictional force between spheroid and the seal ring more and more big, resistance was increasing when ball valve was rotated, and electrical consumption power is big, required also high to motor; Simultaneously, directly influenced the interior sealing index of electric ball valve, so on the power consumption index of product and interior sealing index, can't satisfy user's requirement because friction for a long time between spheroid and the seal ring causes the wearing and tearing of seal ring.
The model utility content
The purpose of this utility model is that a kind of big, high-power problem of electric ball valve required rotation torque of when work that both solved is provided for the technical deficiency that solves above-mentioned electric ball valve, does not produce the eccentric electric ball valve of the novel structure of leakage in the time of guaranteeing to close valve again.
In order to achieve the above object, a kind of eccentric electric ball valve of the utility model design, comprise valve gap, valve body, support sleeve, back shaft, eccentric sphere, valve rod, O shape circle, retarder, motor, retarder links to each other with valve rod, the valve rod head is geometric form and matches with the eccentric opening that eccentric sphere top is opened, valve rod drives the eccentric sphere rotation when making switch valve, form the eccentric sphere sphere and make cam mode motion structure with valve rod, the location is supported by back shaft in the eccentric sphere lower end, is provided with sealing seat and the seal ring of adjusting impacting force between valve body and eccentric sphere.It can be square, flat, triangle, ellipse and other geometric form of determining that described valve rod head is geometric form.
The resulting eccentric electric ball valve of the utility model is characterized in: ball valve is selected fixedly spherical ball valve for use; Spheroid is eccentric spheroid, utilizes the working principle of cam mode, and spheroid most of the time in rotatablely moving is not contacted with seal ring, has reduced friction, has reduced driving torque, has also reduced power consumption simultaneously, has saved the energy; Spheroid is few with contacting of seal ring, and the wearing and tearing of seal ring are also few, the working life of having improved valve greatly.
Description of drawings
Fig. 1 is the utility model eccentric electric ball valve close valve state cross-sectional schematic;
Fig. 2 is the utility model eccentric electric ball valve close valve state structure principle chart schematic representation.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, a kind of eccentric electric ball valve that present embodiment is described, comprise valve gap 1, valve body 2, sealing seat 3, seal ring 4, support sleeve 5, back shaft 6, eccentric sphere 7, valve rod 8, O shape circle 9, retarder 10, motor 11, retarder 10 links to each other with valve rod 8, valve rod 8 heads are square and match with the eccentric opening 12 that opens on eccentric sphere 7 tops, valve rod 8 drives eccentric sphere 7 rotations when making switch valve, form eccentric sphere 7 spheres and make cam mode motion structure with valve rod 8, eccentric sphere 7 lower ends are supported and the location by back shaft 6, are provided with sealing seat 3 and the seal ring 4 of adjusting impacting force between valve body 2 and eccentric sphere 7.This moment, eccentric sphere 7 guaranteed not leaking of water or gas medium by compressing seal ring 4, and eccentric sphere 7 is regulated by sealing seat 3 with the impacting force size of seal ring 4.
Open the valve process: motor 11 drives valve rod 8 by retarder 10 and does motion counterclockwise, as shown in Figure 2, sphere centre 13 is corresponding with runner center 14, owing to move so eccentric sphere 7 spheres are made the cam mode with valve rod 8 not on same point in the sphere centre 13 of eccentric sphere 7 and the valve rod center 15 of valve rod 8.When valve rod 8 drive eccentric spheres 7 are done counterclockwise to rotate together, only need rotate very small angle, just broken away between eccentric sphere 7 and the seal ring 4 and contacted, the follow-up middle eccentric sphere 7 that rotatablely moves has not just contacted entirely with seal ring 4, rotate to 90 ° up to valve rod 8, this moment the through hole of eccentric sphere 7 and seal ring 4 the hole to the jail, the valve full open.
In closing the valve process, valve rod 8 will be done the clockwise direction rotation with motor 11 and retarder 10, driving eccentric sphere 7 simultaneously rotates, begin to closing before valve is about to put in place from closing valve, eccentric sphere 7 does not contact all the time with seal ring 4, when valve rod 8 is about to rotate to 90 °, eccentric sphere 7 just begins to contact with seal ring 4, utilize the eccentric cam mode to make eccentric sphere 7 compress seal ring 4, guarantee interior good airproof performance, thereby finish the valve work of closing.
