Abstract
The utility model relates to a sealing rotating joint for transporting fluid between body rotation and solid, which comprises a rotating shaft, a casing and a sealing device; the sealing device is composed of an elastic component, a rotating ring and a fixing ring; the body rotation is sleeved tightly with the rotating shaft, and smooth end surfaces of the body rotation and the fixing ring are jointed fixedly by the elastic component to reach the sealing aim. The medium leakage problem of the existing rotating joint can be solved effectively; the utility model can be used under the condition of high work rotary speed, and can be used for medical treatment, mechanical industry, chemical industry, etc.
Description
The utility model relates to a kind of swivel joint, the seal swivel joint that has fluid to carry between solid of rotation and fixed body in particularly a kind of.
Existing seal swivel joint structure is made up of Sealing 1, running shaft 2, housing 3 etc. as shown in Figure 1.Sealing 1 adopts filler or leather cup, with the sealing means of running shaft 2 be the circumferential surface sealing.After the sealing material wearing and tearing, will cause dielectric leakage when rotated.And when rotatablely moving, it is comparatively serious to generate heat owing to rubbing between solid of rotation and the Sealing, thereby only is applicable to the occasion of low speed rotation.
The purpose of this utility model is that the sealing configuration to swivel joint makes improvements, to solve dielectric leakage and to adapt to the problem of high speed rotating.
The utility model is realized in the following way: this seal swivel joint comprises running shaft, housing and seal arrangement.Seal arrangement is made up of resilient member, rotating ring and retaining ring.Resilient member is connected with rotating ring, and tightly is enclosed within on the running shaft and rotates with running shaft.Fixing shrink ring is outside running shaft and keep certain clearance.Rotating ring and retaining ring are fitted mutually with smooth end face, and by resilient member rotating ring are fitted tightly on retaining ring.Seal with sealing material between retaining ring and housing.
In swivel joint when work, by the pressure of resilient member and medium, produce suitable impacting force on the contact surface of rotating ring and retaining ring, these two end faces are fitted tightly, and between end face, keep one deck as thin as a wafer medium film and reach the purpose of sealing.When wearing and tearing take place in sealing surface, under the effect of spring force, can compensate automatically, two end faces are remained fit tightly, thereby guarantee that medium does not leak.Simultaneously, because sealing surface is smooth, add the cooling action of fed sheet of a media, the temperature rise of sealing surface is not obvious, thereby not only can be used as common seal swivel joint, and is suitable for the seal swivel joint of making high speed rotary motion spare.
Fig. 1 is existing seal swivel joint structural representation;
Fig. 2 is a seal swivel joint structural representation of the present utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
With reference to Fig. 2, the seal swivel joint of present embodiment comprises running shaft 8, housing 9 and seal arrangement, has attacked outside thread on the running shaft 8, can be connected with solid of rotation, has attacked internal thread on the housing 9, can be connected with fixed body.According to the installation requirement of solid of rotation, running shaft can be made into different amount.Seal arrangement is made up of rotating ring 4, retaining ring 6 and resilient member.Resilient member comprises spring seat 1, spring 2 and gland 3, gland 3 respectively with spring seat 1 and rotating ring 4 tablings, 8 interference fit of spring seat 1 and running shaft are so that spring seat 1, gland 3, rotating ring 4 rotate simultaneously with running shaft 8.Retaining ring 6 is enclosed within outside the running shaft 8, and keeps certain clearance.Rotating ring and retaining ring are made with the high-abrasive material with good lubrication performance, and cause smooth contact surface.During work, the frictional heat that sealing surface produces is less, adds the cooling action of fed sheet of a media, and the temperature rise of sealing surface is not obvious, and the working speed of running shaft can reach 3000 rev/mins, and short-term can be up to 5000 rev/mins.In using seal ring 5 and seal ring 7 sealings between rotating ring 4 and the running shaft 8 and between retaining ring 6 and the housing 9 respectively, because these two seal points are static seals, difficult generation is worn and torn and is caused leaking, thereby can not influence the sealability of this swivel joint.
The advantages such as this seal swivel joint has good seal performance, working speed height, the life-span is long, the scope of application is wide can be widely used in the industries such as medical treatment, machinery, chemical industry.
Claims (2)
1, a kind of seal swivel joint, comprise running shaft, housing and seal arrangement, it is characterized in that: seal arrangement is made up of resilient member, rotating ring and retaining ring, resilient member is connected with rotating ring, and tightly be enclosed within on the running shaft and rotate with running shaft, Fixing shrink ring is outside running shaft and keep certain clearance, and rotating ring and retaining ring are fitted mutually with smooth end face, and by resilient member rotating ring is fitted tightly on retaining ring, seal with sealing material between retaining ring and housing.
2, seal swivel joint according to claim 1 is characterized in that resilient member comprises spring seat, spring and gland, gland respectively with spring seat and rotating ring tabling, interference fit between spring seat and running shaft.
