Description
Technical field
The present invention relates to a kind of ball valve, in particular to a kind of lock controlled ball valve.
Background technique
Ball valve be for chemical industry, fuel gas transmission and city gas supply, water service pipeline in it is a kind of common
Valve, structure is simple, switch is reliable, long service life.Therefore, it is widely used in above-mentioned field.Ordinary construction ball valve
Can directly be manipulated by user as needed, there is control freedom degree and flexibility for end user, but to gas supply, supply water
Control is just lost for management unit, the forfeiture of this control, engineering construction does not complete or do not have gas supply in front end
When water supply conditions, after valve is misused or operates without authorization, there are the security risks of tap water, gas leakage, or stolen
Risk.It is now valvular to prevent from opening means without authorization mainly including that valve rod is pulled to Interface design for special purpose interface form, valve
Spanner or handwheel are not configured on door, can only be opened by special messenger's special spanner or dedicated handwheel.This specific purpose tool necessarily uses
Facilitate the snap-in structure of connection and taking-up, connection precision is low, fastness is poor, is easy to appear skidding, shadow after a period of use
It rings and opens and closes effect；And structure size is big, it is inconvenient to carry.Although occurring currently on the market some with locking machine
Structure, and by the ball valve of private key progress locking and unlock, but these ball valves are not in the presence of structure is complicated, are exactly in the presence of operation
Inconvenient deficiency.Such as Chinese patent notification number CN204312756U, April 4 2012 publication date, invention and created name
The utility model patent of " ball valve " discloses a kind of ball valve, which is provided with a kind of with locking between handle and valve body
Screw, and by the locking device of private key unlock and locking, Key structure size is small, easy to carry, locking and unlock
Rapid operation.But the valve could unlock after needing to remove locking screw, and there are the deficiencies that cumbersome and screw is easily lost.
For this purpose, needing to be further improved.
Summary of the invention
The purpose of the present invention is to the deficiencies in the prior art, provide a kind of lock controlled ball valve, which utilizes locking spiral shell
Nail locks spanner by the filling container outer wall of valve body, and when locking screw is only detached from filling container outer wall or limiting block tongue, i.e.,
Spanner can be unlocked；Its locking screw can only be turned by specialized opener, and misoperation of valve is effectively prevent to open or by without authorization
It opens, it is ensured that user is using safe, and opener structure size is small, easy to carry, locking and unlocks easy to operate, dynamics
It is small, long service life.
To achieve the above object, the present invention adopts the following technical scheme that.
A kind of lock controlled ball valve, including valve body, valve deck and spool, spool are connected with spanner by valve rod, and valve rod is located at valve body
The limiting block tongue of restricted spanner rotational angle range is formed in the filling container that side is equipped with, on spanner；The limiting block tongue with
The locking screw that head is formed with triangular prism or the columnar screwing structure of pintongs plum blossom, lock are equipped between the filling container outer wall of valve body
Only screw is used to lock the spanner by filling container outer wall, and only de- with filling container outer wall or limiting block tongue in locking screw
From when, spanner is unlocked.
Using the present invention of preceding solution, by the way that locking spiral shell is arranged between spanner and the filling container outer wall of valve body
Nail, for spanner and valve body to be formed lockup state.Locking is real by the limiting block tongue of spanner and the filling container outer wall of valve body
Existing, locking can be formed by not needing too great dynamics, lock high reliablity, and lock operation dynamics is small, and when unlock need to only turn
Screw makes it release connection relationship with one of them, is not required to remove screw, easy to operate, unlock rapidly, eliminates spiral shell
Nail loses hidden danger.Meanwhile locking screw is hidden or covered using limiting block tongue, other general works cannot be used to further ensure that
Tool or spanner turn, and have and obtain compact structure.Since the screwing structure on locking screw head is in triangular prism or pintongs plum
Therefore style structure can only turn realization lock by the matched quincunx sleeve opener of triangle or pintongs
Fixed and unlock operation, other any general utility tools or spanner cannot be unlocked or be locked；And locking screw head uses triangle
Or the quincunx screwing structure of pintongs, it is ensured that the seamed edge on locking screw head is not easy rounded, damage in use, from structure
On ensure it with long service life.
Preferably, the locking screw is screwed on the limiting block tongue, and the head of locking screw is hidden in limiting block tongue
In the counterbore being equipped with.It when using this structure, is usually coaxially set by the threaded hole that counterbore and locking screw screw togather, is convenient for screw thread
Bottom outlet and counterbore disposably drill and ream or bore ream and complete the process, and to improve processing efficiency, reduce manufacturing cost.
Preferably, the spanner is in T shape, and spanner is sleeved on the outer of the valve rod by the vertical portion at T-shaped middle part
End, and torque transfer arrangement is formed by two parallel flat horizontal surfaces, and the outer end of valve rod is hidden in valve body.So that wrench-shaped
At T-shaped knob structure, torque transmitting is reliable and compact-sized, simple, and easy to process, manufacturing cost is low.
Preferably, the spanner is fixedly connected with the valve rod by screw, which has phase with the locking screw
Same screwing structure, and the head of screw is hidden in the counterbore that the spanner is equipped with, and is passed through gland and covered.It can effectively prevent
Spanner is dismantled without authorization, eliminates the hidden danger unlocked by dismantling spanner, and can further cramped construction.
Compared with the prior art, the invention has the advantages that locking screw can only be turned by specialized opener, effectively
Prevent misoperation of valve from opening or being opened without authorization, it is ensured that user is using safe, and opener structure size is small, carrying side
Just, locking and unlock are easy to operate, dynamics is small, long service life, and locking screw is without loss hidden danger.
