Abstract
The utility model discloses a pressure regulating valve rod connecting device on cleaning machine, including pressure regulating valve rod and coupling nut, the one end of pressure regulating valve rod is installed in the coupling nut, between being connected, the coupling nut is provided with O type sealing washer with the pressure regulating valve rod, the cover is equipped with the sealing ring on the pressure regulating valve rod, the pressure regulating valve rod is pegged graft there is the steel ball seat, be provided with a plurality of steel balls on the steel ball seat, the air -vent valve inserts is installed to the bottom of pressure regulating valve rod. The advantage: the utility model discloses novel structure through the setting of sealing ring and steel ball seat, has the effect of location to reach and to guarantee that the pressure regulating valve rod reciprocates along the axial of setting for, and pressure output is stable, through sealing ring and O type sealing washer, makes to have strengthened the leakproofness, setting through a style of calligraphy recess for the pressure regulating cap is rotatory rather than the cooperation, and with the efficiency that reaches the pressure regulating, it is very convenient to use.
Description
Technical field
This utility model belongs to cleaning machine component technology field, especially relates to the pressure regulator valve rod connecting device on a kind of cleaning machine.
Background technology
At present, being widely used jetting machine in the industries such as daily production, life, chemical industry, road, airport, the difference according to use occasion, required pressure range is bigger.
High pressure cleaning pump is usually constructed with pressure regulator valve for regulating high pressure cleaning pump discharge pressure, and pressure regulator valve lever apparatus is the parts that pressure regulator valve is indispensable.And the pressure regulation valve rod of prior art is installed, due to long use, it is easy to produce certain skew, it is impossible to ensure that pressure regulation valve rod is back and forth moving accurately along design direction so that pressure regulation operates and causes there is certain error, cause pressure output instability；But pressure regulator valve lever apparatus structure of the prior art is excessively simple, installs firm not, and sealing there is also certain problem；Therefore improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that the pressure regulator valve rod connecting device on a kind of cleaning machine, it have be able to ensure that pressure regulation valve rod along set axially move up and down, the feature of sealing that pressure output is stable and good.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that the pressure regulator valve rod connecting device on a kind of cleaning machine, including pressure regulation valve rod and coupling nut；One end of described pressure regulation valve rod is arranged in coupling nut；Described coupling nut is provided with O RunddichtringO between being connected with pressure regulation valve rod；Described pressure regulation valve rod is set with sealing ring；Described pressure regulation valve rod is plugged with steel ball seat, and described steel ball seat is provided with some steel balls；The bottom of described pressure regulation valve rod is provided with pressure regulator valve inserts.
The head of described pressure regulation valve rod is provided with yi word pattern groove.
The middle part of described pressure regulation valve rod is set with elastomeric pad.
It is provided with O RunddichtringO between described steel ball seat and pressure regulator valve inserts.
After adopting said structure, compared to the prior art this utility model has the advantage, that this utility model novel structure, setting by sealing ring and steel ball seat, there is the effect of location, to reach to be able to ensure that pressure regulation valve rod axially moves up and down along what set, and pressure output is stable, by sealing ring and O RunddichtringO so that enhance sealing；Setting by yi word pattern groove so that pressure regulation cap is mated rotation, to reach effect of pressure regulation, uses very convenient.
Accompanying drawing explanation
Fig. 1 is the explosive view of this utility model pressure regulator valve rod connecting device.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, below in conjunction with drawings and Examples, this utility model is further illustrated.
Embodiment, as shown in Figure 1, the pressure regulator valve rod connecting device on a kind of cleaning machine, including pressure regulation valve rod 10 and coupling nut 11；Coupling nut 11 is connected with pressure adjusting roller, pressure regulating valve device can be driven to do the motion of pressure regulation by the rotation of pressure adjusting roller.One end of pressure regulation valve rod 10 is arranged in coupling nut 11；The head of pressure regulation valve rod 10 is provided with yi word pattern groove 16；Setting by yi word pattern groove 16 so that pressure regulation cap protuberance and its clamping also rotate, and to reach effect of pressure regulation, use very convenient.Coupling nut 11 is provided with O RunddichtringO 12 between being connected with pressure regulation valve rod 10, strengthens the sealing of its connection.The middle part of pressure regulation valve rod 10 is set with elastomeric pad 17；Make installation more firm.Pressure regulation valve rod 10 is set with sealing ring 13, there is good sealing.Pressure regulation valve rod 10 is plugged with steel ball seat 14, steel ball seat 14 is provided with some steel balls, by the setting of the rolling of steel ball and steel ball seat 14, has positioning action, to reach to be able to ensure that pressure regulation valve rod 10 axially moves up and down along what set so that pressure output is stable.The bottom of pressure regulation valve rod 10 is provided with pressure regulator valve inserts 15, has good locking action, reaches the effect consolidated.O RunddichtringO 12 it is provided with so that enhance sealing between steel ball seat 14 and pressure regulator valve inserts 15.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
