Description

Nozzle body with heating sleeve for aerospace instrument

Technical Field

The utility model discloses a nozzle body of taking heating jacket for aerospace apparatus specifically is aerospace apparatus articles for use technical field.

Background

In recent years, a new round of exploration in the international aerospace field is promoted, and further control of "confidentiality" and resources of space is desired. The countries are busy in researching and developing rockets and satellites, developing manned space technology, making a plan for exploring moon and mars, and trying to conquer space in one step by a predecessor, and none of the schemes is 'no hoof stopping by the horse'. Besides the ability to obtain important strategic benefits and economic benefits, the investment of various countries in the aerospace field also increasingly shows the important significance of the "astrology right" on national security and development.

Because the aerospace apparatus mostly operates at high altitude, the temperature is lower, and the used nozzle needs to install the heating jacket to guarantee the temperature in the nozzle, and the nozzle body of current area heating jacket is mostly applicable to the high frequency vibrations environment, and heating efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a nozzle body of area heating jacket for aerospace instrument to solve the current nozzle body of taking the heating jacket that proposes among the above-mentioned background art and be applicable to high frequency vibration environment mostly, problem that heating efficiency is low.

In order to achieve the above object, the utility model provides a following technical scheme: the nozzle body with the heating jacket for the aerospace instrument comprises a nozzle, wherein clamping grooves are uniformly formed in the circumference of the outer wall of the nozzle, the heating jacket is sleeved on the outer wall of the nozzle, a sealing cover is screwed on the top of the heating jacket, a wire walking hole is formed in the outer wall of the heating jacket, a heating bin is formed in the top wall of the heating jacket, a clamping block is uniformly and fixedly mounted on the circumference of the inner wall of the heating jacket, and a weight reduction groove is formed in the top wall of the clamping block

Preferably, the cross sections of the clamping groove and the clamping block are in one of a trapezoid shape or a fan shape.

Preferably, the weight reduction groove is communicated with the heating bin.

Preferably, a sealing gasket is arranged between the bottom wall of the sealing cover and the top wall of the heating jacket.

Compared with the prior art, the beneficial effects of the utility model are that:

1) the device is characterized in that a clamping groove is formed in the outer wall of the nozzle, a clamping block is fixedly mounted on the inner wall of the heating sleeve, the clamping block is clamped with the clamping groove, the connection stability between the heating sleeve and the nozzle is improved, the outer wall of the clamping block is in contact with the inner wall of the clamping groove, the contact area between the inner wall of the heating sleeve and the outer wall of the nozzle is improved, and the heating effect is improved;

2) this device has seted up the heated warehouses at the antetheca of heating jacket, through placing heating device in the heated warehouses inner chamber, seals the heated warehouses through sealed lid, avoids high frequency vibrations to lead to breaking away from of heating device, and this device simple structure, convenient to use is applicable to the high frequency vibrations environment, and heating efficiency is high.
