Design method of quick sampling boiler

Abstract

The invention relates to a design method of a quick sampling boiler. The design method is characterized in that: the quick sampling boiler comprises a feed inlet, a feed outlet and a heating unit; a sampler is arranged on the side wall of the boiler; a sampling chamber is communicated with the interior of the boiler; a sampling hole of the sampler can slide or rotate between the outer part and inner part of the boiler; a first seal ring is arranged at the part, near the sampling chamber, of the head part of a sliding chamber of a base; a second seal ring and a third seal ring are arranged at the parts, near the sampling chamber, of the tail part of the sliding chamber of the base; the distance between the second seal ring and the third seal ring is larger than the width of the sampling hole; the sampling chamber is isolated from the sliding chamber through the first seal ring; the sealing chamber is isolated from the external air through the second seal ring and the third seal ring; a first blind hole is formed in the head end of a sampling rod, and a second blind hole is formed in the tail end of the sampling rod; the sampling hole is isolated from the first blind hole and the second blind hole; the first blind hole and the second blind hole are communicated through a ventilation channel. According to the design method, the sealing effect of the seal rings is improved and the service life of the seal rings is prolonged through the design of the blind holes; the two seal rings with a small wire diameter are adopted, so that the tensile force or thrust during sampling is decreased, and the sampling speed is increased.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a design method for a rapid sampling boiler. Background technique [0002] The air pressure in the boiler is usually inconsistent with the air pressure of the outside atmosphere. When it is necessary to detect and analyze the liquid in the boiler, it must be sampled first, so some sampling ports will be set on the boiler. There are two common approaches. 1. Install a ventilation valve on the top of the boiler, and set a sampling valve at the bottom of the boiler. When sampling is required, first open the ventilation valve to make the air pressure inside the boiler equal to the outside air pressure, then open the sampling valve to complete the sampling. 2. Install a pipe with 3 valves on the boiler. The liquid in the pipe and the liquid in the boiler are circulating. First close two of the valves to isolate the liquid between the two valves from the boiler. Sampling is accomplished by op...
