Abstract

The utility model discloses a gate valve with a slide gate for a steel ladle. In the existing structure, the method that springs directly support a gate plate is changed into the method that a spring compressing device indirectly supports the gate plate. The utility model is characterized in that two spring boxes are respectively installed on a door frame, the springs are placed in the spring boxes, spring pressing plates press on the springs and contact elbow blocks, and the elbow blocks are connected with an installing plate via a connecting rod. in the utility model, the service life of the springs can be effectively extended, and the springs can not be damaged due to high temperature, and accident that the steel of blowby between an upper and a lower gate plates can not occur. For the structure, the utility model has economy, safety, and commonality.

Description

A kind of steel ladle slide gate nozzle gate valve

The utility model relates to a kind of liquid metal casting ladle gate valve, specifically the hold down gag in the molten steel casting ladle slide gate nozzle gate valve is improved.

The as above FHK-2C shaped steel water casting ladle gate valve (Fig. 1, shown in Figure 2) that uses of steel in the prior art, fitting tightly of the upper and lower gate valve plate of the slide gate nozzle sliding surface of this class molten steel casting ladle is by being arranged in the spring compression in the slider bar, spring directly contacts with lower flashboard, spring is subjected to very easily to damage behind the high temperature, thereby cause blowby steel accident between the upper and lower flashboard of gate valve, in addition such flashboard be shaped as ellipse, size is bigger, materials are also many.

The purpose of this utility model is to improve the resiliency supported mode of sliding frame on the basis of existing this class molten steel casting ladle gate valve, makes spring not fragile, thereby avoids the generation of blowby steel accident between the upper and lower flashboard of gate valve.

The technical solution of the utility model is to realize like this, existing spring is directly supported flashboard to be become spring and supports flashboard indirectly, it comprises that mainly one can be contained in the installing plate on the terminal pad at the bottom of the ladle and place upper flashboard in the installing plate, place the lower flashboard in the slider bar, the doorframe and the spring attachment with matching of supporting slider bar and lower flashboard, it is characterized in that: this spring attachment is by spring box, spring, spring bearer plate, connecting rod, elbow piece pivot pin and key seat are formed, be specially: two spring boxs are installed on the doorframe respectively, at least be provided with two spring bases in the spring box, spring is placed in the spring box, spring bearer plate is pressed on the spring and with the elbow piece and touches mutually, and the elbow piece links to each other with installing plate by connecting rod.

The utility model supports flashboard indirectly because the spring in the existing structure is directly supported the spring that flashboard is modified in the spring attachment, prolonged the service life of spring very effectively, thereby prevented spring Yin Gaowen from damaging and caused the generation of blowby steel accident between upper and lower flashboard, structurally with on the performance have more economy, on fitting operation, have more security reliability and versatility.

The utility model will be further described below in conjunction with drawings and Examples.

The utility model comprises that can be contained in the installing plate 4 on the terminal pad at the bottom of the ladle, inserting a hollow brick 1 in the hole of installing plate 4 is located on the installing plate 4 upper flashboard 2, and with pressing tight plate 18, puller bolt 19 is with the upper flashboard pretension, lower flashboard 3 places on the backing plate 9 of slider bar 10, backing plate 9 and slider bar 10 also can be made of one, and doorframe 6 is connected with key seat 5 on being contained in installing plate 4 by doorframe hinge 7 and pivot pin 8, and doorframe 6 can play the effect of supporting slider bar 10 and lower flashboard 3; Spring attachment comprises spring box 11, spring 12, spring bearer plate 13, connecting rod 14, elbow piece 15, pivot pin 16 and key seat 5, concrete structure is: two spring boxs 11 are installed in the outside of doorframe 6 respectively, at least be provided with two spring bases in the spring box, present embodiment is provided with five spring bases, there are five springs 12 to be placed on the interior spring base of spring box, spring bearer plate 13 is pressed on the spring 12 and with elbow piece 15 and touches mutually, elbow piece 15 links to each other with key seat 5 on being arranged on installing plate by connecting rod 14 and pivot pin 16, owing to adopt this hold down gag, lower flashboard 3 evenly can be pressurizeed by spring 12 with upper flashboard 2 and be adjacent to, the ball pivot bar 17 that is arranged on the slider bar 10 can open or close position promotion lower flashboard 3 on request, on, lower flashboard is made by refractory material, be wound with ferrule all around, the metal asbestos board is pasted in the bottom surface, also can directly used for refractory material metal iron-clad be wrapped up, on, lower flashboard be shaped as oval, littler than existing flashboard materials, after overall package is good with installing plate with bolt with fixedly connected at the bottom of the casting ladle and can come into operation, also can earlier installing plate be connected with at the bottom of the steel ladle with bolt, in the hole of installing plate, insert a hollow brick then, upper flashboard is located on the installing plate assembles by the front description again.
