Description

Gate valve lock

Technical Field

The utility model relates to a valve lock technical field, concretely relates to floodgate valve lock.

Background

The gate valve is a shutter plate, the moving direction of which is perpendicular to the fluid direction, and the gate valve can only be fully opened and fully closed, but cannot be adjusted and throttled. Gate valves are sealed by the contact of the valve seat and gate plate, and the sealing surface is usually welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate plate is divided into a rigid gate plate and an elastic gate plate according to the difference of the gate plate.

The gate valve is generally applied to the chemical industry, however, the gate valve switch on the spot is generally in a non-protection state at present, anyone can operate the plug valve switch, if staff misoperation exists, serious consequences can be caused, and certain potential safety hazards exist.

Preferably, the box body inboard is equipped with a plurality of cuboid archs down, be equipped with columniform fixture block in the cuboid arch, go up the box body inboard be equipped with a plurality of with the draw-in groove that the fixture block mutually supported.

Preferably, the fixture block is made of rubber and can be just inserted into the fixture groove.

Preferably, semicircular openings are formed in one sides of the upper box body and one side of the lower box body.

Preferably, the upper box body and the lower box body are both made of PTFE.

The utility model discloses following beneficial effect has:

this floodgate valve lock, easy operation can prevent indiscriminate operation, effectively improves the security of whole equipment to corrosion resisting property is strong, can be durable lasting under adverse circumstances such as open air, high temperature, low temperature.

Detailed Description

In order to make the objects and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-3, the embodiment of the utility model provides a gate valve lock, including last box body 1 and lower box body 2, it is hollow structure to go up box body 1 and box body 2 inside down, it is the same semi-circular structure of radius with lower box body 2 to go up box body 1, it is equipped with first lug 11 to go up box body 1 one side, the opposite side is equipped with second lug 13, all be equipped with circular through-hole 211 in the middle of first lug 11 and the second lug 13, box body 2 one side is equipped with third lug 21 down, the opposite side is equipped with lug assembly 25, lug assembly 25 includes two fourth lugs 251 that the shape is the same, the distance of being separated by between two fourth lugs 251 just can insert second lug 13, all be equipped with circular through-hole 211 in the middle of third lug 21 and the fourth lug 251.

In the structure, insert second lug 13 between two fourth lugs 251, and pass circular through-hole 211 on second lug 13 and the fourth lug 251 with screw nut and fix, after fixed the completion, go up box body 1 and form a hollow circular cavity in inside after the box body 2 closure down, and go up box body 1 and can open with lower box body 2, the biggest opening angle is 180, during the use, embolia the valve switch department of gate valve with last box body 1 and lower box body 2 jointly, after the closure, first lug 11 and third lug 21 mutually support, utilize the circular through-hole 211 on first lug 11 and the third lug 21 of outside tool to lock, pin last box body 1 and lower box body 2, effectively improve the security of whole equipment.

Further, 2 inboards of lower box body are equipped with a plurality of cuboid archs 24, are equipped with columniform fixture block 23 on the cuboid arch 24, go up 1 inboard of box body and be equipped with a plurality of draw-in grooves 12 of mutually supporting with fixture block 23, when going up box body 1 and lower box body 2 closure, in the draw-in groove 12 is just gone into to fixture block 23, stability when further strengthening the closure.

Furthermore, the fixture block 23 is made of rubber and can be just inserted into the fixture groove 12, and the rubber has certain damping performance and enhances the stability during closing.

Furthermore, semicircular openings 22 are formed in one sides of the upper box body 1 and the lower box body 2.

Further, the upper box body 1 and the lower box body 2 are made of PTFE (polytetrafluoroethylene), are made of PTFE materials, are high in corrosion resistance and can be durable in outdoor, high-temperature, low-temperature and other severe environments.

To sum up, the utility model discloses device easy operation can prevent indiscriminate operation, effectively improves the security of whole equipment to corrosion resisting property is strong, can be durable under adverse circumstances such as open air, high temperature, low temperature lastingly.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
