Abstract
The utility model discloses a rust -resistant device of dying for electrical ball valve, including valve rod and valve rod cover, at least, it has an annular to open on the valve rod, install little sealing washer in the annular, the valve rod cover is established it is in the valve rod cover, sealed through little sealing washer, valve rod cover outer wall is opened there is the external screw thread. The utility model discloses an installing a valve rod cover that adopts the wear resistant non -metallic material of the smoothness preparation of polyformaldehyde preparation additional between the table body and valve rod, effectually keeping apart two metal material of the valve rod and the water gauge table body and separate, avoid direct contact, the dead possibility of just so can greatly reduced electric valve being become rusty has a practical meaning to many now the intelligent water gauge of the metal material of electrical ball valve for the data acquisition.
Description
Technical field
This utility model is related to a kind of anti-rust device for electrical ball valve.
Background technology
With the promotion of family table engineering and stepped water pricing policy, intellectual water meter is promoted from the beginning with its prominent functionality advantage
The technological progress of water charge metering, is also increasingly becoming the important selection of water sector.On market today, there are various difference materials
The water meter of matter, but the water meter (as copper shell table, cast iron shell etc.) of wherein metal material still accounts for the larger market share, and metal material
The water meter of matter itself, because table has the material problem of valve and table body, is susceptible to the problems such as get rusty.For intellectual water meter,
Valve is vital performance indications, the problem finding during the use of intellectual water meter, mainly leak, valve
It is unable to completely close, valve loses function etc., and cause the main cause of these phenomenons to be in use because water quality is asked
Topic, causes the position that valve rod is contacted with water meter to be become rusty extremely, this can affect the normal work of valve, greatly shortens the longevity of product
Life.
Content of the invention
This utility model purpose is for the deficiencies in the prior art, provides a kind of anti-rust device for electrical ball valve.
The technical scheme in the invention for solving the technical problem is: a kind of anti-rust device for electrical ball valve, bag
Include valve rod and valve stem sleeve；One annular groove is at least had on described valve rod, in described annular groove, small sealing ring is installed；Described valve stem sleeve
It is located in described valve stem sleeve, sealed by small sealing ring；Described valve stem sleeve outer wall has external screw thread.
Further, described annular groove quantity is two.
Further, also include large sealing packing ring；Described large sealing packing ring is set on the outer wall of valve stem sleeve.
Further, the material of described valve stem sleeve is polyformaldehyde.
The beneficial effects of the utility model are: by installing the light adopting polyformaldehyde to make between table body and valve rod additional
Valve rod and two metal material isolation of water meter can effectively be separated by the valve stem sleeve that the wear-resisting nonmetallic materials of cunning make,
Avoid direct contact with, thus can substantially reduce electrically operated valve by dead probability of becoming rusty, electric ball is adopted for majority now
For the intellectual water meter of the metal material of valve, there is Practical significance.
Brief description
The utility model is further described below in conjunction with the accompanying drawings；
Fig. 1 is the general assembly drawing that this utility model is arranged in the whole table of finished product；
Fig. 2 is the partial enlarged drawing in Fig. 1；
In figure, 1- valve ball 2- table body 3- valve rod 4- small sealing ring 5- valve stem sleeve 6- large sealing packing ring.
Specific embodiment
As shown in Fig. 2 as a kind of embodiment of the present utility model, it includes valve rod 3 and valve stem sleeve 5；On described valve rod 3
Have two annular grooves, small sealing ring 4 is installed in described annular groove；Described valve rod 3 is set in described valve stem sleeve 5, by little close
Seal 4 seals；Described valve stem sleeve 5 outer wall has external screw thread.The material of described valve stem sleeve 5 is polyformaldehyde, plays isolation valve rod 3 He
The effect of the direct metal friction of table body 2；Also include large sealing packing ring 6；Described large sealing packing ring 6 is set on the outer wall of valve stem sleeve 5.
As shown in figure 1, this utility model is arranged in intellectual water meter, for connect the motor drive mechanism in intellectual water meter and
Ball valve 1, particularly as follows: valve stem sleeve 5 is screwed on table body 2, and is sealed by large sealing packing ring 6, the lower end of valve rod 3 and valve ball
1 is connected, and the upper end of valve rod 3 is connected with motor drive mechanism, by the rotation of motor drive mechanism, realizes the rotation of valve ball 1.This utility model
It is applied to intellectual water meter, the watchcase of this intellectual water meter can be metal or plastics.
It should be appreciated that this utility model is not limited to be described above and accurate knot illustrated in the accompanying drawings
Structure, and various modifications and changes can carried out without departing from the scope.Scope of the present utility model only will by appended right
Ask to limit.
