Abstract
The invention relates to a small-bore sealing structure for a downhole watermeter control valve. The small-bore sealing structure comprises a valve body, a valve rod and a motor chamber. The connecting end at the upper end of the valve rod extends out to the outside of a valve rod sleeve at the upper end of the valve body. The valve rod sleeve of the valve body is fixedly connected with the bottom face of the motor chamber. The small-bore sealing structure is characterized in that a locating stage is arranged at the upper end of the valve rod sleeve; a valve rod mounting hole is formed in the bottom face of the motor chamber; a locating groove in embedded connection with the locating stage at the upper end face of the valve rod sleeve is formed in the periphery of the valve rod mounting hole; an O-shaped ring used for sealing the valve rod mounting hole formed in the bottom face of the motor chamber is mounted on the valve rod in an embedded mode. The small-bore sealing structure for the downhole watermeter control valve is scientific and reasonable in structural design, high in innovativeness and capable of achieving good sealing of the valve rod of the watermeter control valve and the portion of the motor chamber.
Description
Counted fields
The invention belongs to water meter field, particularly a kind of minor caliber down water meter control valve seals structure.
Background count
Downhole radio-frequency card intellectual water meter is applicable to industrial and commercial enterprises, government departments and institutions and settlement place and goes into the well
The cold water inside installed and used measures and automatically controls.Downhole radio-frequency card intellectual water meter is by water meter, control
Valve, control motor are constituted.On the inlet tube of water meter install control valve, the valve rod of control valve stretch out into
Outside mouth pipe, and it is connected with the motor shaft controlling motor in motor bin.Owing to the valve rod of control valve exists
There is when installing with valve body the frame momentum on axially, therefore, be that motor bin coordinates and seals
Time, often there is the dislocation between the installing hole of motor bin bottom surface, causes close in the sealing ring on valve rod
Envelope lost efficacy.
Summary of the invention
It is an object of the invention to overcome the deficiency of existing counting, it is provided that a kind of motor bin bottom surface and control
The valve rod of valve processed realizes being accurately positioned and sealing, and is prevented effectively from liquid and enters in motor bin from valve body
Minor caliber down water meter control valve seals structure.
The present invention is solved its enumeration problem and is realized by following count protocol:
A kind of minor caliber down water meter control valve seals structure, including valve body, valve rod and motor bin,
Valve rod upper end connect end extend out to outside the valve stem sleeve of valve body upper end, the valve stem sleeve of valve body with
The bottom surface of motor bin is fixing to be connected, it is characterised in that: described valve stem sleeve upper end is shaped with positioning table,
The bottom surface of described motor bin is shaped with valve rod installing hole, is shaped with and valve in the periphery of this valve rod installing hole
Bar puts the locating slot that end face positioning table is chimeric, is embedded with and described motor bin bottom surface institute on valve rod
The O that the valve rod installing hole of system seals.
And, the depths of described locating slot is 1.2mm.
And, it is embedded with twice lower seal between described valve rod and valve stem sleeve.
Advantages of the present invention and having the beneficial effect that
1, this minor caliber down water meter control valve seals structure, and valve stem sleeve upper end is shaped with positioning table,
The bottom surface of described motor bin is shaped with valve rod installing hole, is shaped with and valve in the periphery of this valve rod installing hole
Bar puts the locating slot that end face positioning table is chimeric, is embedded with and described motor bin bottom surface institute on valve rod
The O that the valve rod installing hole of system seals, the depths of locating slot is 1.2mm, by locating slot
It is accurately positioned, it is ensured that O is in inside the axial height of valve rod installing hole, immediately there is frame
Momentum, does not falls out the outside of valve rod installing hole yet, thus ensure that between valve rod and motor bin
Sealing.
2, this minor caliber down water meter control valve seals structure, is embedded with two between valve rod and valve stem sleeve
Road lower seal, improves the sealing effectiveness between valve rod and valve body upper end valve stem sleeve further.
3, present configuration design science is reasonable, can realize valve rod and the motor bin portion of water meter control valve
The excellent sealing of position, is that a kind of minor caliber down water meter control valve with higher innovation seals knot
Structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Description of reference numerals:
1-motor bin, 2-positioning table, 3-lower seal, 4-O shape circle, 5-valve rod, 6-valve stem sleeve.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, and following example are illustrative, no
It is determinate, it is impossible to limit protection scope of the present invention with this.
A kind of minor caliber down water meter control valve seals structure, including valve body, valve rod 5 and motor bin 1,
The end that connects of valve rod upper end extend out to valve stem sleeve 6 outside of valve body upper end, the valve stem sleeve of valve body
Fixing with the bottom surface of motor bin and be connected, its innovation is: valve stem sleeve upper end is shaped with positioning table 2,
The bottom surface of motor bin is shaped with valve rod installing hole, be shaped with in the periphery of this valve rod installing hole with on valve stem sleeve
The locating slot that end face positioning table is chimeric, the depths of locating slot is 1.2mm.Valve rod is embedded with
The O 4 of the valve rod installing hole sealing that described motor bin bottom surface is made.Accurate by locating slot
Location, it is ensured that O is in inside the axial height of valve rod installing hole, immediately there is frame momentum,
Do not fall out the outside of valve rod installing hole, thus ensure that the sealing between valve rod and motor bin yet
Property.
Twice lower seal 3 it is embedded with between valve rod and valve stem sleeve.Improve further on valve rod and valve body
Sealing effectiveness between end valve stem sleeve.
Although disclosed embodiments of the invention and accompanying drawing for the purpose of illustration, but the counting of this area
Personnel are appreciated that without departing from the present invention and spirit and scope of the appended claims, various
Replace, to change and modifications be all possible, and therefore the scope of the present invention is not limited to embodiment and attached
Figure disclosure of that.
