Abstract
The utility model relates to an adjustable thermal test seal device. The adjustable thermal test seal device consists of a compression cover, a connecting element and a high-temperature-resistant silica gel seal ring. When a thermal test is carried out, an end B of the connecting element is installed on a test point; the compression cover compresses the high-temperature-resistant silica gel seal ring into a space of an end A of the connecting element by adjusting a fine thread; the silica gel seal ring is compressed to reach an appropriate tightening force by rotating the compression cover so as to achieve a seal effect. The adjustable thermal test seal device provided by the utility model eradicates the problems of not thorough seal of an original seal device, severe dust pollution, high measurement data errors and poor safety of working areas of workers, and has the beneficial effects of comprising few parts, being low cost, increasing friction between hands and the surface of the device, and being convenient to operate.
Description
Technical field
The utility model relates to a kind of adjustable heating power test packoff.
Background technology
In thermal power generation process, need to calcine produce power to coal dust, sometimes need the parameters such as the wind speed in stove, fineness of pulverized coal to measure.Conventionally heating power survey crew need to carry out with Portable high temperature anemoscope measuring wind speed and the demarcation of boiler, because the aging design defect of original packoff is outstanding, sealing effectiveness completely without.High temperature coal dust ejection when measuring four jiaos of wind speed of boiler in tube cell, environmental pollution is very serious, the difficulty and the error of measured data that have greatly increased while measuring large simultaneously, and the personal safety of survey crew is caused to very large hidden danger, is difficult to improve and solve always.
Summary of the invention
The purpose of this utility model is intended to solve the packing less shortcoming of thermal test water-tight equipment, and a kind of adjustable heating power test packoff is provided, and its concrete scheme is:
A kind of adjustable heating power test packoff, by friction top, web member and high temperature resistant silica gel O-ring seal form, wherein web member A end is provided with one for placing the space of high temperature resistant silica gel O-ring seal, in opening, be provided with internal thread, B end is provided with the external thread suitable with testing site internal thread, friction top bottom is provided with the external thread suitable with web member A end internal thread, described high temperature resistant silica gel O-ring seal is placed in web member A end spaces, high temperature resistant silica gel O-ring seal is I-shaped shape, by the size of the adjustable high temperature resistant silica gel O-ring seal bore of exerting pressure, it is adjustable fine thread that the suitable external thread of internal thread is held with web member A in friction top bottom, the suitable external thread of web member B end and testing site internal thread is coarse thread.
The utlity model has following advantage: stopped original water-tight equipment blow-by, during measurement, dust pollution is serious, and error of measured data is large, the problem of personnel perform region safety, and parts are few, and cost is low, increases the friction force of hand and apparatus surface, easy to operate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated: a kind of adjustable heating power test packoff, by friction top 1, web member 2 and high temperature resistant silica gel O-ring seal 3 form, wherein the B of web member 2 end is provided with the external thread suitable with testing site internal thread, A end is provided with one for placing the space of high temperature resistant silica gel O-ring seal 3, in opening, be provided with internal thread, friction top 1 bottom is provided with the external thread suitable with the A end internal thread of web member 2, described high temperature resistant silica gel O-ring seal 3 is placed in the A end spaces of web member 2, friction top 1 screws can oppress high temperature resistant silica gel O-ring seal 3 distortion, the surface of friction top 1 is also provided with anti-slip veins.
Example 1: carrying out measuring wind speed and the timing signal of boiler with high temperature anemoscope, heating power survey crew need to be arranged on thermal test packoff on tube cell, extend into the probe of anemoscope in the middle circular hole of packoff, measures.
The B end of web member 2 is arranged on tube cell, friction top 1 is by regulating fine thread high temperature resistant silica gel O-ring seal 3 to be depressed in the A end spaces of web member 2, according to the diameter of anemoscope probe, regulate friction top 1, oppress high temperature resistant silica gel O-ring seal 3, high temperature resistant like this silica gel O-ring seal 3 pressurizeds, inwall forms projection, bore diminishes to suitable with anemoscope probe diameter, like this anemoscope probe is stuck in completely to the prominence of high temperature resistant silica gel O-ring seal 3, seamless, prop up malleation in stove, in stove, coal dust can not leak, and plays sealing effectiveness.
The utility model significant sealing affection, has stopped the problem of dust pollution, and the accuracy of measurement data while having guaranteed test also guaranteed staff's personal safety problem, and parts is few, and cost is low, increases the friction force of hand and apparatus surface, easy to operate.
