Abstract
The utility model relates to a small -bore valve of water meter controller in pit seal structure, including valve body, valve rod and motor storehouse, the link of valve rod upper end stretches out to the valve rod cover outside of valve body upper end, the valve rod cover of valve body and the bottom surface fixed connection in motor storehouse, and its characterized in that: valve rod cover upper end system have the location platform, the bottom surface system in motor storehouse have a valve rod mounting hole, the periphery system of this valve rod mounting hole have with the constant head tank of valve rod cover up end location platform gomphosis, inlay on the valve rod be equipped with with the O that the valve rod mounting hole the is sealed shape circle that made motor storehouse bottom surface. The utility model discloses structural design scientific and reasonable can realize the valve rod of water meter controller valve and the good of motor storehouse position and seal, is a small -bore valve of water meter controller in pit seal structure who has higher novelty.
Description
Technical field
This utility model belongs to water meter field, particularly a kind of minor caliber down water meter control valve sealing structure.
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, controlled motor.The inlet tube of water meter
Upper installation control valve, the valve rod of control valve stretches out outside inlet tube, and is connected with the motor shaft of the controlled motor in motor bin.Due to
The valve rod of control valve has the frame momentum in axial direction with valve body when installing, therefore, when being that motor bin coordinates and sealed,
Often the dislocation and the installing hole of motor bin bottom surface between in sealing ring on valve rod, causes seal failure.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the valve of a kind of motor bin bottom surface and control valve
Bar is realized being accurately positioned and sealing, and is prevented effectively from liquid and enters the minor caliber down water meter control valve sealing in motor bin from valve body
Structure.
This utility model solves its technical problem and is achieved through the following technical solutions：
A kind of minor caliber down water meter control valve sealing structure, 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：Described valve stem sleeve upper end is formed with positioning table, and the bottom surface of described motor bin is formed with valve rod installing hole, installs in this valve rod
The periphery in hole is formed with the locating slot chimeric with valve stem sleeve upper surface positioning table, is embedded with and described motor bin bottom surface institute on valve rod
The O-ring of the valve rod installing hole sealing of system.
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.
Advantage of the present utility model and having the beneficial effect that：
1st, this minor caliber down water meter control valve sealing structure, valve stem sleeve upper end is formed with positioning table, described motor bin
Bottom surface be formed with valve rod installing hole, be formed with the positioning chimeric with valve stem sleeve upper surface positioning table in the periphery of this valve rod installing hole
Groove, is embedded with the O-ring of the valve rod installing hole sealing made with described motor bin bottom surface, the depths of locating slot is on valve rod
1.2mm, being accurately positioned it is ensured that O-ring is in inside the axial height of valve rod installing hole by locating slot, immediately there is frame
Momentum, does not fall out the outside of valve rod installing hole yet, thus ensure that the sealing between valve rod and motor bin.
2nd, this minor caliber down water meter control valve sealing structure, is embedded with twice lower seal between valve rod and valve stem sleeve,
Improve the sealing effectiveness between valve rod and valve body upper end valve stem sleeve further.
3rd, rationally, the valve rod of achievable water meter control valve is good with motor bin position for this utility model scientific structure design
Sealing, is a kind of minor caliber down water meter control valve sealing structure with higher innovation.
Brief description
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：
1- motor bin, 2- positioning table, 3- lower seal, 4-O shape circle, 5- valve rod, 6- valve stem sleeve.
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.
A kind of minor caliber down water meter control valve sealing structure, including valve body, valve rod 5 and motor bin 1, valve rod upper end
Connection end extend out to outside the valve stem sleeve 6 of valve body upper end, and the valve stem sleeve of valve body is fixedly connected with the bottom surface of motor bin, its innovation
Part is：Valve stem sleeve upper end is formed with positioning table 2, and the bottom surface of motor bin is formed with valve rod installing hole, in this valve rod installing hole
Periphery is formed with the locating slot chimeric with valve stem sleeve upper surface positioning table, and the depths of locating slot is 1.2mm.Valve rod is embedded with
The O-ring 4 of the valve rod installing hole sealing made with described motor bin bottom surface.It is accurately positioned it is ensured that O-ring by locating slot
It is in inside the axial height of valve rod installing hole, immediately there is frame momentum, also do not fall out the outside of valve rod installing hole, thus
Ensure that the sealing between valve rod and motor bin.
It is embedded with twice lower seal 3 between valve rod and valve stem sleeve.Improve further valve rod and valve body upper end valve stem sleeve it
Between sealing effectiveness.
Although disclosed embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art is 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.
