Abstract
A built-in lock rod device of a fire valve mainly comprises a rod outer sleeve, a cover cap and a valve rod, wherein the cover cap is arranged at the upper end of the rod outer sleeve; the inner cavity of the rod outer sleeve is a cavity which is also an inner regular hexagon, and a push rod and a passive push rod are sequentially and tightly arranged in the cavity from top to bottom; a regular hexagon inner hole is formed in the center of the upper end of the valve rod; the utility model discloses simple structure, unlocking means conceals, as long as open the block after, withstands downwards and promote the push rod, drives passive push rod and pushes away the regular hexagon in the hole to make the outer hexagonal of passive push rod coincide with the interior six shapes in the regular hexagon hole and be connected the back just, the rotation rod cover is the valve rod and follows the rotation promptly, in case the valve rod rotates the back, the valve can be opened, and very portably, and locking device is difficult to discover.
Description
Technical Field
The utility model belongs to the technical field of the fire control gate valve accessory, concretely relates to be a compact structure, reasonable in design's fire control valve's built-in locking lever device.
Background
The valve is used very extensively in daily life and industrial production, and in order to prevent that the valve from being operated by irrelevant personnel, set up certain locking device on the gate valve usually and prevent that irrelevant personnel from opening the valve at will, traditional gate valve sets up obvious trick lock or other lockable device in the outside of valve usually, all exposes in the outside of valve, and the disguise is not strong, suffers artificial vandalism easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, provide a disguise is stronger, and locking device is difficult to the built-in locking lever device of the fire valve door by the discovery.
In order to achieve the above object, the utility model provides a following technical scheme: a built-in lock rod device of a fire valve mainly comprises a rod outer sleeve, a cover cap and a valve rod, wherein the cover cap is arranged at the upper end of the rod outer sleeve; the method is characterized in that: the inner cavity of the rod outer sleeve is a cavity which is also an inner regular hexagon, and a push rod and a passive push rod are sequentially and tightly arranged in the cavity from top to bottom; the center of the upper end of the valve rod is provided with a regular hexagon inner hole.
The push rod and the driven push rod are both regular hexagon push rods, and the size of each regular hexagon push rod corresponds to the size of the inner hole of each regular hexagon.
And a spring is fixedly arranged at the bottom of the regular hexagonal inner hole.
The cover cap is screwed on the top surface of the rod outer sleeve.
The utility model has the advantages that: compared with the prior art, the utility model discloses simple structure, unlocking means is hidden, as long as open the block after, withstands downwards and promote the push rod, drives passive push rod and pushes away the regular hexagon inner hole to make the outer hexagonal of passive push rod coincide with the interior six shapes in the regular hexagon hole and couple together just, the rotation is followed to the rotating rod cover promptly valve rod, in case the valve rod rotates the back, the valve can be opened, and is very simple and convenient, and locking device is difficult to discover.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. capping; 2. a push rod; 3. a regular hexagonal inner hole; 4. a valve stem; 5. a spring; 6. a passive push rod; 7. the rod is sleeved outside.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides the following technical solutions: a built-in lock rod device of a fire valve mainly comprises a rod outer sleeve 7, a cover cap 1 and a valve rod 4, wherein the cover cap 1 is arranged at the upper end of the rod outer sleeve 7; the rod outer sleeve 7 can also be used as a hand wheel for rotary arrangement; the inner cavity of the rod outer sleeve 7 is a cavity which is also an inner regular hexagon, and the push rod 2 and the passive push rod 6 are sequentially and tightly arranged in the cavity from top to bottom; the passive push rod 6 can move downwards together under the push of the push rod 2; a regular hexagon inner hole 3 is formed in the center of the upper end face of the valve rod 4; the push rod 2 and the driven push rod 6 which are arranged in the rod outer sleeve 7 are both formed by connecting inner hexagons
Push rod 2 and passive push rod 6 be regular hexagon appearance push rod, the corresponding setting of size and regular hexagon hole 3 size of its regular hexagon push rod forms, consequently after passive push rod 6 is pushed interior regular hexagon hole 3, passive push rod 6 and valve rod 4 be connected and rely on regular hexagon's outer pole and the identical installation of regular hexagon hole completely.
And a spring 5 is fixedly arranged at the bottom of the regular hexagonal inner hole 3.
The cap 1 is screwed on the top surface of the rod outer sleeve 7.
The utility model discloses the use method does: the valve rod 4 is arranged on the gate valve, and the valve of the gate valve can be opened through the rotation of the valve rod 4; in a natural state, the driven push rod 6 pushes the driven push rod 6 out of the regular hexagon inner hole 3 under the action of the elastic force of the spring 5, and after the driven push rod 6 pushes out of the regular hexagon inner hole 3, no matter how the outer sleeve 7 is rotated, the valve rod cannot rotate; when needs use the gate valve, open block 1, push up 2 downwards hard with push rod for passive push rod 6 moves down and enters into regular hexagon hole 3 up to the removal in, dwang overcoat 7 again, in the dwang overcoat 7, drives valve rod 4 promptly and rotates, thereby just can open the valve of gate valve.
Claims (2)
1. A built-in lock rod device of a fire valve consists of a rod outer sleeve, a cover cap and a valve rod, wherein the cover cap is arranged at the upper end of the rod outer sleeve; the method is characterized in that: the inner cavity of the rod outer sleeve is a cavity which is also an inner regular hexagon, and a push rod and a passive push rod are sequentially and tightly arranged in the cavity from top to bottom; a regular hexagon inner hole is formed in the center of the upper end of the valve rod; the push rod and the driven push rod are both regular hexagon push rods, and the size of each regular hexagon push rod is arranged corresponding to the size of the regular hexagon inner hole; and a spring is fixedly arranged at the bottom of the regular hexagonal inner hole.
