Abstract
The utility model relates to a water-saving mechanical sealing device. A static ring is arranged in a static ring seat and provided with a static ring sealing ring; a moving ring component is arranged at the corresponding position at the inner side of the static ring; the static ring is provided with a limiting plate; and a gland bush gasket is arranged outside the static ring seat. By adopting an integrated structure, the water-saving mechanical sealing device is convenient to install and simultaneously adjust the compression amount of side seal and main seal of medium. A dowel is riveted on a driving ring of the moving ring component and plays the roles of super guidance and rotation prevention. Because of being free from a push ring used by normal mechanical seal, the water-saving mechanical sealing device reduces the driving resistance, improves the driving efficiency, thereby not only reducing the axial installation size of mechanical seal, but also ensuring that the following performance of mechanical sealing is better and the compensation performance is more excellent. A protective hood is formed on the exircle of the driving ring, accommodates a moving ring and a spring in the moving ring component, and prevents excessive dust in the air from falling into the moving ring component to block the spring to lead to losing elasticity or the ash from attaching to a shaft sleeve to influence the slipping of an O-shaped ring of the moving ring on the shaft sleeve so as to cause water-saving mechanical seal to lose efficiency.
Description
Technical field
The utility model relates to a kind of mechanical seal device.
Background technique
High temperature pump in the petrochemical industry all is furnished with the cooling water clean-up line, and on the gland of mechanical seal water deflector cover is installed, and prevents that cooling water from leaking.Because water deflector cover adopts the rubber material to be made substantially, and is not wear-resistant, and is generally interference fit between water deflector cover and the axle sleeve.Equipment is after running after a while, and water deflector cover is because wear and tear, and the change of the radial clearance between the axle sleeve is big, causes the cooling water vent flow to strengthen.The cooling water that leaks often is thrown out of along running shaft, sprays to be everywhere.Especially after leaking at some side medium mechanical seal, with cooling water pollution, cooling water leaks in the atmosphere and goes, and causes serious environmental to pollute, and entire field is formed very big potential safety hazard, does not more reach environmental requirement.As shown in Figure 3, be water deflector cover form commonly used.When installing, because magnitude of interference is excessive, the water deflector cover inward flange is scratched by axle sleeve through regular meeting, leak immediately behind the feeding cooling water.
Summary of the invention
At the defective that existing water deflector cover mechanical seal device exists, the utility model provides the axial installation dimension of a kind of mechanical seal little, simple and practical, cooling water does not take place leak in a large number, the mechanical seal device of befouling environment.
Solving the problems of the technologies described above the concrete technical measures of being taked is: a kind of water saving mechanical seal device, it is characterized in that: stationary ring (2) is housed in stationary seat (1), stationary ring O shape circle (3) is housed on stationary ring (2), at the inboard opposite position of stationary ring (2) moving ring assembly (4) is housed, limiting board (5) is housed on stationary ring (2), goes up the outside at stationary seat (1) gland pad (6) is housed.
Moving ring assembly (4) structure is: spring (22) is housed in the rotating ring groove, and spring outside pin (24) is connected with transmission ring (26), and rotating ring O shape circle (23) is housed on rotating ring (21), and transmission screw (25) is housed on the transmission ring (26).
Beneficial effect of the present invention: adopt integrated structure, the convenient installation adjusted the decrement of side medium primary seal simultaneously.Riveting has pin on the transmission ring of moving ring assembly, plays guiding and anti-rotation.The throw-out collar that does not need normal mechanical sealing to use reduces the transmission resistance, increases transmission efficiency, has not only reduced the axial installation dimension of mechanical seal, more make mechanical seal to follow performance better, compensation performance is better.Transmission ring forms a protective housing at the cylindrical place, rotating ring in the moving ring assembly, spring are included in the inside, prevent that dust too much in the atmosphere from falling into moving ring assembly, spring is blocked the mistake bullet, perhaps dust adhesion is on axle sleeve, influence the slippage of rotating ring O shape circle on axle sleeve, the mechanical seal that causes economizing on water was lost efficacy.
Description of drawings

Fig. 2 is a moving ring assembly structural representation among Fig. 1.
Fig. 3 is existing water deflector cover schematic diagram of sealing device.
Embodiment
Accompanying drawings structure of the present utility model.
A kind of water saving mechanical seal device as depicted in figs. 1 and 2, is equipped with stationary ring 2 in stationary seat 1 bottom, and stationary ring O shape circle 3 is housed on stationary ring 2, and stationary ring 2 adopts graphite material, realizes sealing with stationary seat 1 by O shape circle interference fit.At stationary ring 2 inboard opposite positions moving ring assembly 4 is housed, the moving ring assembly structure is: in rotating ring 21 grooves spring 22 is housed, spring outside pin 24 is connected with transmission ring 26, and rotating ring O shape circle 23 is housed on rotating ring 21, and transmission screw 25 is housed on the transmission ring.Rotating ring surface of friction pair in the moving ring assembly 4 selects for use surperficial spraying or pile-up welding hard alloy and other hard materials that can make friction pair all can.The material of rotating ring can be chosen 2Cr13, draws materials extensively, and is with low cost.The effect that the while rotating ring also serves as spring case directly gets out spring eye, transmission pin hole on rotating ring, riveting has pin on the transmission ring of moving ring assembly 4, plays guiding and anti-rotation.The throw-out collar that does not need normal mechanical sealing to use reduces the transmission resistance, increases transmission efficiency, has not only reduced the axial installation dimension of mechanical seal, more make mechanical seal to follow performance better, compensation performance is better.In addition, the thickness of transmission ring suitably extends, quite form a protective housing at the cylindrical place, rotating ring, spring in the moving ring assembly 4 are included in the inside, prevent that dust too much in the atmosphere from falling into moving ring assembly 4, spring blocked lose bullet that perhaps dust adhesion is on axle sleeve, influence the slippage of rotating ring O shape circle 23 on axle sleeve, the mechanical seal that causes economizing on water was lost efficacy.Limiting board 5 is housed on stationary ring 2, utilizes limiting board 5 that the transmission ring in stationary seat 1 and the moving ring assembly 4 is coupled together.In stationary seat 1 outside asbestos gland pad 6 is housed, realizes sealing between stationary seat 1 and the mechanical seal cover.
