The further optimization of the kiln pressure relief and pressure taking connecting bolt further comprises that the sealing element 2 is of a weight-shaped structure with a double-layer cylinder, wherein the outer circular surface of the cylinder 2a with the larger diameter at the lower part is a smooth surface and is matched with a smooth sealing surface, the middle part of the cylinder 2b with the smaller diameter at the upper part is provided with a connecting groove 2c, and the top of the connecting groove 2c is provided with a notch 2 d; the lower extreme of interior screw rod is equipped with connecting portion, and connecting portion 3a is the cylinder that can insert in spread groove 2c, and connecting portion 3a passes through spliced pole 3b with interior screw rod and is connected, and spliced pole 3b diameter is less than connecting portion 3a and can block in the breach 2 d. The structure is convenient to process and manufacture, simple to use and operate, high in flexibility and beneficial to use and maintenance of the structure.
The further optimization of the kiln pressure relief and pressure taking connecting bolt further comprises an elastic body arranged between the bottom surface of the sealing element 3 and the step surface 1c, wherein the elastic body is made of a plastic material with a high thermal expansion coefficient, and a hole is formed in the middle of the elastic body. The elastomer can improve the sealing performance of the connecting bolt when pressure is taken out without pressure relief after the connecting bolt is installed, and after the inner bolt is screwed in, the elastomer under the influence of high temperature on one side of the kiln can fill a gap between the bottom surface of the sealing element and the step surface, so that the sealing performance of the inner part is further improved, and the conventional performance of the bolt is ensured.
The beneficial effects are that:
in the utility model, the main bolt not only plays a role of connecting various structures of the kiln as a common connecting piece, but also needs to be used as a supporting piece of a pressure relief and pressure taking structure, so that the hole structure at the bottom of the main bolt can be directly communicated with the inner cavity of the kiln when being installed, for example, a screw hole for installing the main bolt is arranged to be a through hole connected to the inside of the kiln; in order to avoid the adverse effect of high temperature in the kiln on the overall structure and functions, the main bolt, the sealing element and the inner screw rod are preferably made of high-temperature-resistant and friction-resistant metal materials; in the specific use process, the main bolts are designed into different lengths according to requirements and are mutually installed on various structures of the kiln to be used as conventional connecting pieces; when needs pressure release, drive sealing member 2 rebound behind the rotatory inner bolt, when the sealing member under the terminal surface move up to the trench position of giving vent to anger and when above position, can utilize the inside gas of the groove of giving vent to anger excretion, perhaps with sealing member and inner screw directly back of screwing out, will get and press and get and press work such as getting in the device screw in kingbolt such as pipe or temperature measurement, based on this design, can be so that the bolt as conventional connecting piece produces more functions, because the bolt is essential structure in the kiln installation use, through utilizing the utility model discloses a connecting bolt replaces conventional bolt, can reduce the required pressure release of original kiln by a wide margin and get auxiliary structure such as pressure, the design cost of producing of kiln is effectively simplified, improves the sealing performance of structure.
Compared with the traditional bolt structure, the utility model discloses its function has been expanded, and low cost, for this connecting bolt easy dismounting of conventional pressure release structure, original kiln structure can effectively be simplified, and then the cost of reduction kiln manufacturing and use.
