Abstract
The utility model discloses a closed-smelting machine hydraulic upper top bolt cooling water sealing device with good sealing property, which comprises a piston-rod [1], a pressure lead [5] which is fixed with a retainer ring [4], a flange [6] and a pressure plate [2], and is characterized in that axial seal rings are respectively arranged on the outer ring of the piston-rod [1] and between the pressure plate [2] and the flange [6], and end face seal rings are respectively arranged on the outer ring of the retainer ring [4] and between the flange [6] and the pressure lead [5]. The closed-smelting machine hydraulic upper top bolt cooling water sealing device has the advantages of simple structure, good sealing property, and which controls leakage of original leakage point cooling water effectively and expands time of usage of the device.
Description
Technical field:
The utility model relates to a kind of banbury hydraulic top ram, specifically a kind of banbury hydraulic top ram cooling water sealing device.
Background technology:
At present, banbury hydraulic top ram cooling water sealing device is to be provided with the sealing of O RunddichtringO between the outer ring of piston rod and ram.Because piston rod is up to two meters, cooling water is big at the pressure of bottom, add the matched in clearance of upper piston rod and ram and the temperature rise of cooling water circulation time, reduced the sealing effectiveness of O RunddichtringO, along with banbury running continuously all the year round, cooling water between pressing plate and flange and position contacted with it produce seepage even leakage.
Summary of the invention:
The purpose of this utility model provides a kind of banbury hydraulic top ram cooling water sealing device of good seal performance.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of banbury hydraulic top ram cooling water sealing device, it comprises piston rod, ram, snap ring, flange and pressing plate are installed on the ram, outer ring at piston rod, be provided with axial sealing ring between pressing plate and the flange,, be provided with end-face seal ring between flange, the ram in the outer ring of snap ring.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and good airproof performance has been controlled former leakage point leakage of cooling water effectively, has prolonged the service time of equipment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A place enlarged diagram of Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As seen from Figure 1, Figure 2, a kind of banbury hydraulic top ram cooling water sealing device, it comprises piston rod 1, ram 5, and snap ring 4, flange 6 and pressing plate 2 are installed on the ram 5, and existing sealing device is to be provided with O RunddichtringO 8 to seal between the outer ring of piston rod 1 and ram 5.For increasing sealing effectiveness, the utility model is provided with axial sealing ring 3 in the outer ring of piston rod 1 between pressing plate 2 and the flange 6, in the outer ring of snap ring 4, is provided with end-face seal ring 7 between flange 6, the ram 5.
The utility model has been controlled former leakage point leakage of cooling water effectively, has prolonged the service time of equipment.
