Abstract
More particularly to a kind of filler ring structure of high voltage adjusting valve group of the utility model.Including at least one set of hard packing ring and at least one set of soft packing ring, the hard packing ring and soft packing ring position setting successively on the valve rod of septum valve along the order by pressure medium in valve from small to large, and oil syringe and oil level detection sensor are respectively equipped with each group of soft packing ring and hard packing ring.The utility model uses special filler ring structure on septum valve, by way of hard packing ring and soft packing ring group are closed, not only increases the sealing property of septum valve, and reduce the abrasion of packing ring；Oil filler point is set at each filler ring group simultaneously, and the oil level at every group of packing ring is detected, it is ensured that the lubrication of valve rod, so as to improve sealing effectiveness, reduce abrasion.
Description
Technical field
The utility model is related to filler ring structure, more particularly to a kind of filler ring structure of high voltage adjusting valve group.
Background technology
Packing seal is frequently used in each plant equipment, carries out the dynamic sealing of motion parts, such as centrifugal pump, compression
The plunger or piston rod of machine, vavuum pump, mixer, the rotating shaft sealing of reactor and reciprocating pump, reciprocating compressor, and do straight
Sealing between line, the valve rod of screw valve and fixed body.Prior art generally using soft packing seal mode or
Hard packing sealing means, need using multiple soft packing rings during soft packing seal, when using in high voltage adjusting valve group,
Because the pressure received is larger, the soft packing ring at the aperture is easily overly compressed, and causes the abrasion of soft packing ring, and away from
Soft packing ring at aperture can not reach the sealing effectiveness of needs due to the insufficient pressure being subject to again.
Utility model content
The utility model provides a kind of filler ring structure of high voltage adjusting valve group, solves techniques discussed above and asks
Topic.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of packing ring knot of high voltage adjusting valve group
Structure, including at least one set of hard packing ring and at least one set of soft packing ring, the hard packing ring and soft packing ring are in septum valve
Valve rod on position setting successively along the order by pressure medium in valve from small to large, near each group of soft packing ring and hard
Oil syringe and oil level detection sensor are respectively equipped with packing ring.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the hard packing ring is carbon fiber and the composite bed or molybdenum bisuphide of tin bronze and being combined for tin bronze
Layer.
Further, the hard packing ring is tin bronze layer, and the tin bronze layer surface is coated with molybdenum bisuphide coating.
Further, the soft packing ring is mixing for graphite annulus, polytetrafluoroethylene ring or graphite annulus and polytetrafluoroethylene ring
Cyclization.
The beneficial effects of the utility model are：The utility model uses special filler ring structure on septum valve,
By way of hard packing ring and soft packing ring group are closed, the sealing property of septum valve is not only increased, and reduce and fill out
Expect the abrasion of ring；Oil filler point is set at each filler ring group simultaneously, and the oil level at every group of packing ring is detected, it is ensured that
The lubrication of valve rod, so as to improve sealing effectiveness, reduces abrasion.
Brief description of the drawings
Fig. 1 is a kind of sectional view of the filling-material structure of high voltage adjusting valve group of the present embodiment.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, be a kind of sectional view of the filling-material structure of high voltage adjusting valve group of the present embodiment, including set gradually
Gland pad 1, gland 2, filler group 3, the collar 4 and pad 5, described filler group 3 include one group of hard packing ring 3.1 and one group
Soft packing ring 3.2, the hard packing ring and soft packing ring on the valve rod of septum valve along by pressure medium in valve from
Small to position setting successively to big order, oil syringe is respectively equipped with each group of soft packing ring and hard packing ring, and (Tu Zhong is saved
Omit) and oil level detection sensor (being omitted in figure).The present embodiment uses special filler ring structure on septum valve, passes through
The mode that hard packing ring and soft packing ring group are closed, not only increases the sealing property of septum valve, and reduce packing ring
Abrasion；Oil filler point is set at each filler ring group simultaneously, and the oil level at every group of packing ring is detected, it is ensured that valve rod
Lubrication, so as to improve sealing effectiveness, reduce abrasion.
In the present embodiment, the hard packing ring is tin bronze layer, and the tin bronze layer surface is coated with molybdenum bisuphide coating,
The soft packing ring is graphite annulus, so as to improve the slickness of hard packing ring surface, improves sealing effectiveness.In other embodiment
In, the hard packing ring is the composite bed or molybdenum bisuphide and the composite bed of tin bronze of carbon fiber and tin bronze, the soft packing
Ring is the mixing ring of polytetrafluoroethylene ring or graphite annulus and polytetrafluoroethylene ring.
The utility model uses special filler ring structure on septum valve, by hard packing ring and soft packing ring group
The mode of conjunction, not only increases the sealing property of septum valve, and reduces the abrasion of packing ring；Simultaneously in each filler
Oil filler point is set at ring group, and the oil level at every group of packing ring is detected, it is ensured that the lubrication of valve rod, so as to improve sealing effect
Really, abrasion is reduced.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
