Abstract
The utility model discloses a mechanical seal, comprising a stationary ring, a movable ring and push rings. A spring is arranged between the two push rings, and the movable ring is provided with a packing which has the sealing function. The push rings and the movable rings are connected with screws, and the push rings can press the packing tightly. The utility model has the advantages of reliable seal, simple structure and high temperature resistance and can be widely used on various high-temperature pumps, corrosive-resistant pumps, ball valves and eccentric valves.
Description
The utility model relates to a kind of mechanical seal.
The existing mechanical sealing is to adopt seal ring, and the seal ring of resistant to elevated temperatures mechanical seal is to adopt expensive exotic material to make, the cost height, and price is expensive.The employing that seal ring has is single, and it is unreliable to seal, the seal of employing double density, though good seal, whole mechanical seal structure complexity is difficult to be generalized on all kinds of high temperature pumps, ball valve, the eccentric valve.
The purpose of this utility model is to provide a kind of mechanical seal, and it is simple in structure, and cost is low, can be applied to all kinds of high temperature pumps well.
The purpose of this utility model is achieved in that packing is installed in the rotating ring, and rotating ring adopts with throw-out collar and is threaded, and throw-out collar compresses packing, is placed with spring between two throw-out collars, and stationary ring is in the outside of rotating ring.
The utility model is owing to be arranged on packing in the rotating ring, by being threaded of rotating ring and throw-out collar, by throw-out collar it is pressed in the rotating ring, and simple in structure, cost is low.Can make with resistant to elevated temperatures asbestos material owing to packing again, so this mechanical seal is high temperature resistant, corrosion-resistant, may be used on all kinds of high temperature pumps and the valve.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional view according to the mechanical seal that the utility model proposes.
Describe details and the working condition of complying with the mechanical seal that the utility model proposes in detail below in conjunction with accompanying drawing.
This mechanical seal has 1, two throw-out collar 3 of 2, two stationary rings of two rotating rings, and packing 5 is installed in the rotating ring 2, and throw-out collar 3 and rotating ring 2 utilizes and be threaded, and throw-out collar 2 also is pressed on packing 5 in the rotating ring 2.Rotating ring 2 can be made with T8 steel, pottery or alloy material, and packing 5 can be made with asbestos, and at least three layers, otch is 30 °.During installation, otch is evenly arranged.Between two throw-out collars 2 spring 4 is installed.The Manufacturing material of spring 4 can need be selected according to heatproof.One end of rotating ring 2 has stationary ring 1, and stationary ring 1 contacts with rotating ring 2 end faces, but relative movement seals.Pressure between spring 4 controllable brakes, the stationary ring end face.
When using this mechanical seal, with stationary ring, in the rotating ring of packing is housed, throw-out collar is installed in the spring between two throw-out collars, is installed on the axle of equipment needed thereby.Stationary ring is fixed on the sealing seat, and dynamic and static ring has certain clearance, packing just in time to fill up the gap of rotating ring and axle with axle, seals.
