Description
Technical field
This utility model belongs to valve technology field, especially relates to a kind of regulation for electronic blank-plate valve chain drive and draws
Lever apparatus.
Background technology
The one safe and reliable partition equipment that electronic blank-plate valve is mounted on gaspipe line.This valve is arranged on outdoor,
When valve is closed, can definitely cut off pipe-line system medium, be that the safety of a kind of reliable cut-out gas medium sets
Standby.And electronic blank-plate valve can realize opening and closing at a distance, reliably cuts off gas medium, be a kind of preferably coal gas and
The security control valve that toxic gas pipeline definitely cuts off.Electric chain formula blank-plate valve is mainly by left valve barrel, right valve barrel, driving wire
Bar, sprocket wheel, the linkage being made up of chain, valve plate, sealing ring, rustless steel compensator, gear revolute, driving means etc. zero
Part forms, and is constituted a rigid structure body by base, support seat, relies on chain drive so that sprocket wheel drives transmission screw mandrel to drive
Dynamic left and right valve body unclamps, clamp YE carries out unclamping or clamping, and realizes the valve opening of electric chain formula blank-plate valve, turns over
The a series of actions such as plate, pass valve.
For electric chain formula blank-plate valve, during assembly and adjustment, there is an outstanding problem: because of three in equipment
Root drive lead screw and three fixing connections of sprocket wheel, and be positioned on three vertex positions of equilateral triangle, chain is around three chains
Wheel is tightened；This causes chain to be wasted time and energy when mounted, installed to add the resistance of rotation tight, debugging pine chain and sprocket wheel
Degree of engagement inadequate, during sprocket wheel chain rotates and uses, chain easily comes off, and additionally user uses process for a long time
In, chain the most easily gets loose, and causes the biggest trouble to assembler and user.
Summary of the invention
It is convenient that the purpose of this utility model is to provide a kind of installation and debugging, and prevent that chain from getting loose for electronic blank-plate valve
Chain drive adjusting yoke device.
The purpose of this utility model is realized by following technical proposals:
Of the present utility model for electronic blank-plate valve chain drive adjusting yoke device, including by one group of end to end chain
The linkage of bar composition, it is characterised in that also include that the afterbody with wherein chain being arranged between each two chain is connected
The left-handed fork that head is connected, the dextrorotation being connected with the stem union joint of another chain fork, one end and described left-handed fork spiral shell
The adjusting yoke that stricture of vagina connects and the other end is threadeded with described dextrorotation fork, left locking nut, right locking nut,
One end of described adjusting yoke is provided with left-handed screw, and the other end is provided with right handed screw, described left-handed screw with
Described left-handed fork is threaded, and described right handed screw is threadeded with described dextrorotation fork.
In flat in the middle part of described adjusting yoke.
Advantage of the present utility model:
Of the present utility model for electronic blank-plate valve chain drive adjusting yoke dress, simple in construction, easy to use, operation is clever
Live, only need to the left during installation and debugging or right rotation adjusting yoke, linkage is adjusted to suitable rate of tension, and locks left and right
Nut can complete；The regulated quantity of adjusting yoke can be adjusted at any time according to practical situation, makes chain operationally be not easy to
Come off, reach the best state of valve transmission.
Accompanying drawing explanation
Fig. 1 is this utility model position view at electronic blank-plate valve.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, of the present utility model for electronic blank-plate valve chain drive adjusting yoke device, including by one group
The linkage of end to end chain 2 composition, it is characterised in that also include being arranged between each two chain 2 with wherein one
The left-handed fork 6 that the afterbody union joint 5 of chain 2 is connected, the dextrorotation being connected with the stem union joint 10 of another chain 2 fork 9,
Threaded with described left-handed fork 6 in one end and the other end pitches 9 adjusting yokes 1 threadeded, left locking with described dextrorotation
Nut 11, right locking nut 12,
One end of described adjusting yoke 1 is provided with left-handed screw 7, and the other end is provided with right handed screw 8, described left-handed screw
7 threaded with described left-handed fork 6, and described right handed screw 8 is pitched 9 with described dextrorotation and threadeded.
In flat in the middle part of described adjusting yoke 1.
After electric chain blank-plate valve global tissue of the present utility model, chain 2 is centered around on three drive lead screws 3
Sprocket wheel 4 on, then adjusting yoke 1 is connected with chain 2, blocks the flat place on adjusting yoke 1 with spanner, to the left or right rotation
Adjusting yoke 1, is adjusted to suitable rate of tension linkage, locks left locking nut 11 and right locking nut 12, and root
According to practical situation can adjusting yoke at any time so that the transmission of valve reaches best state.This utility model is in assembling process
In by rotate adjusting yoke 1, just chain 2 can be adjusted to required elasticity, not only increase the work efficiency of assembling, also
Solve the use difficult problem of onsite user.
