Utility model content
This utility model embodiment technical problem to be solved is, it is provided that a kind of replacing filler, plunger, the maintenance man-hours of valve group and fittings cost of being greatly decreased, the utilization rate of raising equipment, has conveying sewage fluid end structure Han granule of good economic benefit.
Described conveying sewage fluid end structure Han granule, including sealed letter body and the valve group that is connected with described sealed letter body, described sealed letter body is double sealing structure, including plunger and be arranged on the peripheral primary seal letter body being sequentially connected with of plunger, primary seal filler, main regulation nut and secondary sealed letter body, secondary airtight and watertight padding, secondary adjusting nut；It is provided with primary seal filler between described primary seal letter body and secondary sealed letter body, secondary sealed letter body is blocked in described main regulation nut one end, the other end is connected with primary seal letter body, described secondary adjusting nut is connected with secondary sealed letter body, described secondary airtight and watertight padding is arranged between described secondary adjusting nut and secondary sealed letter body, described primary seal letter body, between secondary seal and plunger, define a cavity, described cavity is provided with oilhole;Described valve group includes the spool with the valve seat that described plunger is connected, being arranged in described valve seat and is successively set on the rubber valve above described spool, rubber valve gland.
Described rubber valve face exceeds spool metallic sealing section 0.5-0.8mm.
Implement this utility model embodiment, have the advantages that
The conveying of this utility model embodiment is containing injecting lubricating oil between granule sewage fluid end structure sealed letter body, plunger, filler, the friction of plunger and filler can be reduced, reduce heating, store particulate contaminant, reduce granule to pull, wear and tear, improve plunger and the service life of filler；Spool uses and nonmetal seals with metallic combination formula, and nonmetal valve face exceeds metal valve face 0.5-0.8mm, when valve cuts out, and first nonmetal valve face contact, then metal valve face contact, reduce and valve face can be collided with the impact clashed into thing, raising valve group service life.Improved by said structure, replacing filler, plunger, the maintenance man-hours of valve group and fittings cost are greatly decreased, improve the utilization rate of equipment, there is good economic benefit.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram；
Fig. 2 is conventional conveying sewage fluid end structure schematic diagram Han granule.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail.
Conventional conveying sewage fluid end structure is shown in accompanying drawing 2, is made up of sealed letter body 1', airtight and watertight padding 2', adjusting nut 3', plunger 4', valve seat 5', spool 6' and adnexa;Utility model conveying sewage fluid end structure Han granule is shown in accompanying drawing 1, including sealed letter body and the grease nipple that is connected with sealed letter body, sealed letter body is double sealing structure, is made up of primary seal letter body 1, primary seal filler 2, secondary sealed letter body 3, plunger 7, main regulation nut 4, secondary airtight and watertight padding 5, secondary adjusting nut 6 and grease nipple 8；It is provided with primary seal filler 2 between primary seal letter body 1 and secondary sealed letter body 3, secondary sealed letter body 3 is blocked in main regulation nut 4 one end, the other end is connected with primary seal letter body 1, secondary adjusting nut 6 is connected with secondary sealed letter body 3, secondary airtight and watertight padding 5 is arranged between secondary adjusting nut 6 and secondary sealed letter body 3, primary seal letter body 1, a cavity 101 is defined between secondary seal 3 and plunger 7, oilhole 102 it is provided with on cavity 101, lubricant grease is injected in described cavity 101 by grease nipple 8, valve group includes valve seat 9, the spool 10 that is arranged in valve seat 9 and be successively set on the rubber valve 11 above described spool 10, valve rubber gland 12, rubber valve face exceeds spool metallic sealing section 0.5-0.8mm.
Sealed letter structure uses dual-seal, and primary seal seals high-pressure medium part, secondary sealing sealing low pressure lubricant grease；By grease nipple, injecting lubricant grease, between primary seal and secondary sealing, lubricant grease is deposited in gap；Spool uses nonmetal with metallic combination formula valve face, and first nonmetal valve face contact sealing surface of seat is, then spool metal covering contact sealing surface of seat.
When piston reciprocation moves, the 75% of plunger spray-welding coating polished surface contacts with lubricant grease, lubrication plunger and filler.
When reciprocating pump termination of pumping, with grease gun by grease nipple, lubricant grease can be added to major-minor airtight and watertight padding gap.
The conveying of this utility model embodiment is containing injecting lubricating oil between granule sewage fluid end structure sealed letter body, plunger, filler, the friction of plunger and filler can be reduced, reduce heating, store particulate contaminant, reduce granule to pull, wear and tear, improve plunger and the service life of filler；Spool uses and nonmetal seals with metallic combination formula, and nonmetal valve face exceeds metal valve face 0.5-0.8mm, when valve cuts out, and first nonmetal valve face contact, then metal valve face contact, reduce and valve face can be collided with the impact clashed into thing, raising valve group service life.Improved by said structure, replacing filler, plunger, the maintenance man-hours of valve group and fittings cost are greatly decreased, improve the utilization rate of equipment, there is good economic benefit.
Above disclosed it is only this utility model one preferred embodiment, certainly can not limit the interest field of this utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
