Abstract
The utility model provides a nozzle chamber of concatenation formula, it includes 4 the same nozzle chamber bodies, a circular shape nozzle chamber is constituteed in two liang of connections of 4 the same nozzle chamber bodies, be equipped with convex mouth of pipe from top to bottom respectively, this mouth of pipe both sides are equipped with the sealing device who is connected with interior cylinder wall respectively, still be equipped with the flange circle in sealing device's upper end, 4 the relative nozzle body of piece is connected through the unsmooth spread groove between two to be equipped with the dentate groove in the spread groove, it has sealed effect better, has saved manpower and material resources, simple structure, and easy maintenance also great improvement to the life of product.
Description
Technical Field
The invention relates to the field of nozzle chambers, in particular to a spliced nozzle chamber.
Background
The nozzle room is commonly used on the steam turbine, and the nozzle room that common steam turbine used all fixes on the steam turbine, but more and more steam turbine kind now, lead to the nozzle room if under the fixed circumstances, in case damage will all change, very resource-wasting to the nozzle room is only a cavity, the storage is used, and is not fragile, but the nozzle room concatenation department of common concatenation formula is not sealed, damages very easily, it is not high to cause the leakproofness well to lead to steam turbine work efficiency.
Disclosure of Invention
The utility model aims at having the above-mentioned problem to current technique, provided one kind and be convenient for the installation, simple structure, convenient to use's a be used for cylinder bottom reinforcing seat.
The purpose of the utility model can be realized by the following technical proposal: the spliced nozzle chamber comprises 4 identical nozzle chamber bodies and is characterized in that the 4 identical nozzle chamber bodies are connected in pairs to form a circular nozzle chamber, convex pipe orifices are arranged at the upper part and the lower part respectively, sealing devices connected with the inner cylinder wall are arranged on two sides of each pipe orifice respectively, a flange ring is further arranged at the upper end of each sealing device, the 4 opposite nozzle chambers are connected through concave-convex connecting grooves between the two nozzle chambers, and tooth-shaped grooves are formed in the connecting grooves. Preferably, the outer side of each nozzle chamber is provided with a half groove, the outer side of each nozzle chamber is connected with the other nozzle chamber to form a complete concave connecting groove, a convex connecting block is arranged on the concave connecting groove, and the connecting convex block plays a role in fixing the splicing between the two nozzle chambers and connecting the air cylinders. Preferably, the sealing device on the pipe orifice is a toothed belt connecting port arranged on the pipe orifice, a layer of elastic gasket with the toothed connecting port in the same manner is arranged outside the toothed connecting port, and the toothed connecting port is coated with anti-skid adhesive tape or glue. The utility model overcomes prior art's is not enough, adopts the recess that can prevent lubricating oil in the bottom setting to the nozzle room of concatenation formula to be equipped with in the both sides of cylinder and place the sawtooth that removes to use, such technique can let the hydro-cylinder remove the in-process that leaves more convenient, the utility model discloses still have simple to operate, convenient to use, characteristics such as easy operation.
Description of the drawings:
FIG. 1 is a schematic flow diagram of the present invention.
Detailed Description
The invention will be described in detail below with reference to the following figures: FIG. 1 shows the following steps: a splicing type nozzle chamber comprises 4 identical nozzle chamber bodies 1, and is characterized in that the 4 identical nozzle chamber bodies are connected in pairs to form a circular 2 nozzle chamber 3, convex pipe orifices 4 are respectively arranged at the upper part and the lower part, sealing devices 5 connected with the wall of an inner cylinder are respectively arranged at two sides of each pipe orifice 4, a flange ring 6 is further arranged at the upper end of each sealing device 5, the 4 opposite nozzle bodies are connected through concave-convex connecting grooves 9 between the two nozzle chambers, tooth-shaped grooves 7 are arranged in the connecting grooves 13, a half groove 8 is respectively arranged at the connecting position of the outer side of each nozzle chamber, a complete concave connecting groove 9 is formed after the two nozzle chambers are connected, a convex connecting block 10 is arranged on the concave connecting groove 9, the connecting convex block 10 plays a role in fixing the splicing between the two nozzle chambers and connecting the cylinder, the sealing device 5 on the pipe orifices is a tooth-shaped belt connecting port 11 arranged on the pipe orifices, a layer of elastic gasket 12 with the same toothed connecting port is arranged outside the toothed connecting port 11, and anti-skid adhesive tapes or glue is coated on the toothed connecting port 11.
The utility model overcomes prior art's is not enough, an improvement has been made to current nozzle chamber, change original nozzle chamber into present concatenation formula, but the problem of concatenation formula lies in the sealing performance of connecting portion and the elasticity of mouth of pipe, so to this the invention makes further improvement to these two parts, in the leakproofness, connect through 4 nozzle chambers of the same size, all be equipped with connecting groove between every two nozzle chambers, and connect with the connecting block, this connecting block passes through the welding mode and welds in the recess, both can work as the mounting, its connecting block has can be regarded as the connecting piece, and set up sealing device at the mouth of pipe, this sealing device has unique connector, adopt the cusp to connect, can place and remove, and further bonding through sticky tape or glue is firm.
