Description
Technical field
This utility model belongs to water meter field, water meter control valve sealing structure under particularly a kind of large-diameter well.
Background technology
Downhole radio-frequency card intellectual water meter is applied to industrial and commercial enterprises, installs and uses in government departments and institutions and resident's missile silo
Cold water measures and automatically controls.Downhole radio-frequency card intellectual water meter is made up of water meter, control valve, gauge outfit controller.Gauge outfit controller
Control valve top can be fixedly mounted on, or installation is connected by lead.Control valve is by valve body, valve element, valve rod and controlled motor.
It is attached with the motor shaft of the controlled motor being arranged in motor bin because valve rod stretches out valve body upper end, need to set on valve rod
Put sealing ring, it is to avoid in valve body, liquid enters into motor bin.Existing sealing ring is usually O-ring, and it has sealing effectiveness and owes
Good problem.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of existing counting, provides a kind of valve stem seal effect good, effectively keeps away
Exempt from water meter control valve sealing structure under the large-diameter well that automatic control liquid valve body enters in motor bin.
This utility model is solved its enumeration problem and is realized by following count protocol：
Water meter control valve sealing structure under a kind of large-diameter well, including valve body, valve rod and motor bin, the company of valve rod upper end
Connect end and extend out to outside the valve stem sleeve of valve body upper end, the valve stem sleeve of valve body is fixedly connected with the bottom surface of motor bin, and its feature exists
In：The corresponding valve stem sleeve end in the connection end of described valve rod is formed with sealing ring erecting bed, installs Y on this sealing ring erecting bed
Shape sealing ring, the upper surface of y-shaped ring is plane, and the upper surface of y-shaped ring is flushed with the upper surface of valve stem sleeve,
The bottom of y-shaped ring is inner seal and outer side seal, is embedded in a lower O-shape ring, institute between inner seal and outer side seal
State motor bin bottom surface and be formed with to should fall the hold-down ring of y-shaped ring.
And, the top of described valve rod connection end is embedded in the upper O-shape ring being sealed with motor bin bottom surface installing hole.
Advantage of the present utility model and having the beneficial effect that：
1st, water meter control valve sealing structure under this large-diameter well, is arranged between the connection end of valve rod and the valve stem sleeve of valve body
There is down y-shaped ring, when installing motor bin, the hold-down ring of motor bin bottom surface compresses to the upper plane of y-shaped ring, this
When fall y-shaped ring inner seal to internal locking, outer side seal supports, to outer locking, middle lower O-shape ring, the sealing of falling Y shape
Circle, it is ensured that it opens to both sides, is realized the sealing to valve rod, effectively prevents the liquid in valve body from entering motor bin from valve rod.
2nd, water meter control valve sealing structure under this large-diameter well, top setting-in and the motor bin bottom surface of valve rod connection end are installed
The upper O-shape ring that hole is sealed, effectively realizes preventing the fluid in motor bin from entering into the purpose in valve body.
3rd, this utility model scientific structure design is reasonable, and the excellent sealing at the valve rod position of achievable water meter control valve is
Water meter control valve sealing structure under a kind of large-diameter well with higher innovation.
Brief description
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：
1- motor bin, 2- screw, 3- valve stem sleeve, 4- fall y-shaped ring, 5- upper O-shape ring, 6- lower O-shape ring, 7- hold-down ring,
8- outer side seal, 9- inner seal, 10- erecting bed, 11- valve rod, 12- connection end.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, and following examples are descriptive, is not to limit
Property it is impossible to protection domain of the present utility model is limited with this.
Water meter control valve sealing structure under a kind of large-diameter well, including valve body, valve rod 11 and motor bin 1, valve rod upper end
Connection end 12 extend out to outside the valve stem sleeve 3 of valve body upper end, the underrun screw 2 of the valve stem sleeve of valve body and motor bin is solid
Fixed connection.Its innovation is：The corresponding valve stem sleeve end in the connection end of valve rod is formed with sealing ring erecting bed 10, in this sealing ring
Install y-shaped ring 4 on erecting bed, the upper surface of y-shaped ring is plane, the upper surface of y-shaped ring and valve rod
The upper surface of set flushes, and the bottom of y-shaped ring is inner seal 9 and outer side seal 8, inner seal and outer side seal it
Between be embedded in a lower O-shape ring 6, motor bin bottom surface is formed with to should fall the hold-down ring 7 of y-shaped ring.When installing motor bin, motor
The hold-down ring in orlop face compresses to the upper plane of y-shaped ring, now the inner seal of y-shaped ring to internal locking,
Outer side seal supports y-shaped ring it is ensured that it opens to both sides, realizes close to valve rod to outer locking, middle lower O-shape ring
Envelope, effectively prevents the liquid in valve body from entering motor bin from valve rod.
The upper O-shape ring 5 that the top setting-in of valve rod connection end is sealed with motor bin bottom surface installing hole.Effectively realize preventing
Fluid in motor bin enters into the purpose in valve body.
Although disclosed embodiment of the present utility model and accompanying drawing for the purpose of illustration, the counting personnel of this area are permissible
Understand, without departing from this utility model and spirit and scope of the appended claims, various replacements, to change and modifications be all can
Can, scope therefore of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
