Abstract
The utility model provides a sealing device of plunger pump intermediate lever, is including the sealed letter body, the sealed and reinforced seal of Y shape, the boss is established into at the sealed internal side of letter middle part, Y shape sealed with the reinforced seal assembly in the sealed internal side of letter and be located the both sides of boss respectively, the sealed letter body, Y shape is sealed and reinforced seal is used for the cover to locate the intermediate lever, the reinforced seal outside is equipped with the gland, the gland is fixed on sealed letter is personally experienced sth. Part of the body. The utility model discloses simple structure, simple to operate with reinforced seal and the sealed sealing method who makes up of Y shape, reduce the wearing and tearing to the intermediate lever, lengthen the life of intermediate lever, reinforced seal is fixed to the gland, avoids reinforced seal to be reciprocating motion along with the intermediate lever, and the running cost of equipment has been saved to the wearing and tearing intermediate lever.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of seal arrangement of plunger pump intermediate bar.
Background technique
At oil, chemical industry, chemical fertilizer industry field generally uses high-pressure plunger pump as flow process pump, the sealing of plunger pump intermediate bar is the primary sealing member of equipment, at present, intermediate bar sealing is packing seal, filler due to wearing and tearing comes off and easily blocks oil diverting port, cause oil return not smooth, intermediate bar leakage of oil is serious, the bad not only serious waste machine oil of intermediate bar sealing, make plunger pump be in the bad state of lubrication for a long time simultaneously, be degrading plunger pump working condition, add equipment operating cost, and filler easily causes intermediate bar surface abrasion, shorten intermediate bar working life, and frequently change intermediate bar, intensity of workers is caused to increase, raising equipment operating cost.
Summary of the invention
The utility model object is intended to the seal arrangement providing a kind of plunger pump intermediate bar, solves intermediate bar Leakage, reduces the wearing and tearing to intermediate bar, extends intermediate bar working life.
Based on above object, the utility model takes following technological scheme:
A kind of seal arrangement of plunger pump intermediate bar, comprise sealed letter body, Y shape sealing and reinforced seal, sealed letter body middle inside is set as boss, Y shape sealing and reinforced seal to be assemblied in inside sealed letter body and to lay respectively at the both sides of boss, the sealing of sealed letter body, Y shape and reinforced seal are for being sheathed on intermediate bar, be provided with gland outside reinforced seal, gland is fixed on sealed letter body.
Preferably, that side that described sealed letter body is equipped with Y shape sealing is provided with Oil Guide lid, and Oil Guide lid is L-shaped, and Oil Guide lid is fixed on sealed letter body.
Preferred further, described Y shape is sealed into the sealing of not contour lip Y shape.
The beneficial effects of the utility model: the utility model structure is simple, easy for installation, with the sealing means of reinforced seal and Y shape seal combination, reduce the wearing and tearing to intermediate bar, extend the working life of intermediate bar; Gland fixes reinforced seal, and avoid reinforced seal to move reciprocatingly along with intermediate bar, wear and tear intermediate bar, saves the operating cost of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of seal arrangement of plunger pump intermediate bar, as shown in Figure 1, comprise sealed letter body 1, Y shape sealing 5 and reinforced seal 3, sealed letter body 1 middle inside is set as boss, Y shape sealing 5 and reinforced seal 3 to be assemblied in inside sealed letter body 1 and to lay respectively at the both sides of boss, sealed letter body 1, Y shape sealing 5 and reinforced seal 3 are for being sheathed on intermediate bar 6, gland 2 is provided with outside reinforced seal 3, gland 2 is fixed on sealed letter body 1 by bolt 7, that side that sealed letter body 1 is equipped with Y shape sealing 5 is equipped with Oil Guide lid 4, Oil Guide lid 4 is L-shaped, Oil Guide lid 4 is fixed on sealed letter body 1, Y shape sealing 5 is the sealing of not contour lip Y shape.
During work, Y shape sealing and reinforced seal are first assemblied on sealed letter body, then bolt 7 stationary gland 2 is used, gland 2 is made to compress reinforced seal 3, after opposite side loads onto Oil Guide lid 4, be set on intermediate bar 6, sealed letter body 1 is fixed on Plunger pump body, and between sealed letter body 1 and the pump housing, surface of contact is sealed by O-ring seals.The mode that the utility model adopts reinforced seal 3 and Y shape sealing 5 to combine, decrease the wearing and tearing to intermediate bar 6 to greatest extent, oil diverting port keeps unimpeded, lubricant oil is not easily leaked outside, saves cost of production.
