Description

Direct insert valve device and combustor Technical Field The utility model relates to the technical field of combustors, in particular to an in-line valve device and a combustor. Background The combustor that uses straight insert valve among the prior art is equipped with limit structure on the injection pipe generally, and the nozzle of straight insert valve inserts and locates in spacing and carry out spacingly through limit structure, because limit structure and injection pipe are general structure as an organic whole, leads to limit structure's thickness to be great generally, and the radiating effect is relatively poor, and the nozzle leads to the temperature higher in being in constrictive high temperature region, also makes the temperature of valve body higher, influences the life of straight insert valve. Disclosure of utility model The utility model aims to overcome the defect that the service life of an in-line valve is influenced due to the fact that the temperature of a joint of an injection pipe and the in-line valve is high in the prior art. The utility model solves the technical problems by the following technical scheme: The utility model provides a direct-insert valve device, which comprises an injection pipe and a nozzle, wherein one end of the injection pipe is provided with an opening, the direct-insert valve device also comprises a limiting piece, the limiting piece comprises a limiting body and an extending part, the limiting body is provided with a first nozzle hole and a first air valve hole, the limiting body is covered on the opening, the first air valve hole is communicated with the opening, and the extending part is arranged on the side edge of the limiting body and extends out of the injection pipe; The nozzle is inserted in the first nozzle hole, a nozzle opening is formed in one end, close to the injection pipe, of the nozzle, the nozzle opening stretches into the inner side of the limiting piece in the thickness direction and is communicated with the opening, and the thickness of the limiting piece is smaller than 2mm. In this scheme, through with spacing piece and the split design of ejecting pipe to can make the thickness of spacing piece thinner, set the thickness of spacing piece to be less than 2mm, compare in limit structure integrated into one piece's ejecting pipe, spacing piece thickness is less, more easily dispel the heat, and spacing piece still includes the extension, and the extension is located spacing body's both sides and is extended to the outside and is ejected the pipe, thereby is convenient for spacing piece heat dissipation more. Because the spacing piece is made thinner, the nozzle opening also stretches into the inboard of the thickness direction of spacing piece more easily, makes the periphery of nozzle opening not sheltered from, and the nozzle opening is in half open space, and the nozzle opening is easier to dispel the heat, and when using, the in-process that the air of penetrating gets into the inside of penetrating the pipe from first air door hole cools off the nozzle repeatedly to can reduce the temperature of nozzle, extension cut straightly the life-span of valve. Preferably, the number of the extending parts is two, and the two extending parts are arranged on two sides of the limiting body and below the center of the nozzle. In this scheme, regard nozzle center as the world, nozzle center's below temperature is lower, locates the below at nozzle center with the extension to more be convenient for dispel the heat, further promoted the radiating effect. Preferably, the limiting piece further comprises a mounting portion, one end of the mounting portion is connected to the limiting body, and the other end of the mounting portion is detachably connected to the injection pipe. In this scheme, through setting up the installation department to the spacing piece of being convenient for more is with the installation and the dismantlement of ejecting pipe, the equipment and the later maintenance of the valve device of cut straightly of being convenient for. The opening is located to spacing body lid, and the installation department is connected in spacing body, and it is located the injection pipe opening part to avoid the mounted position to be connected through the installation department, reduces the influence to the injection effect. Preferably, the mounting part extends along the insertion direction of the nozzle, and the mounting part is abutted against the outer surface of the injection pipe. In this scheme, extend along the direction of insertion of nozzle through with the installation department, and the installation department laminating is supported and is leaned on in the surface of penetrating the pipe to be connected with penetrating the pipe more convenient for installation department, and make the installation department and penetrate the connection of pipe more firm. In addition, the installation department also can play radiating e
