Embodiment Construction

[0031] In order to distinguish the head and the tail of the parts, the part close to the handle 204 is called the tail, and the part far away from the handle 204 is called the head.

[0032] Such as figure 1 As shown, a sampler is installed near the bottom of the side wall of the boiler, and the sampling rod 2 is in the insertion position. When it is necessary to sample the liquid in the boiler, the sampling rod 2 only needs to be pulled out, and the sampling hole on the sampling rod 2 is 202 is fully exposed, that is, the sampling rod 2 is in the pulled out position (see Figure 8 ), turn the sampling rod 2 (see Figure 5 ), that is, the liquid in the sampling hole 202 is poured into the container, and then the sampling rod 2 is rotated and pushed back to the insertion position. The sampling process only needs three actions, one pull, one turn and one push, which is convenient and fast, with less actions, short time and high sampling efficiency.

[0033] Such as figure 2...

Abstract

The invention relates to a fast sampler used on a boiler. The fast sampler comprises a matrix and a thief rod which are in closed sliding or running fit. Part of a sliding cavity is communicated with the outside air through a ventilating channel. The fast sampler is characterized in that the head part of the matrix's sliding cavity, close to a sampling cavity, is provided with a first seal ring; the tail part of the matrix's sliding cavity, close to the sampling cavity, is equipped with second and third seal rings; axial distance between the second seal ring and the third seal ring is greater than width of a thief hole in the axial direction of the thief rod; the sampling cavity is isolated from the sliding cavity through the first seal ring; the sampling cavity is isolated from the outside air through the second and third seal rings; the head end of the thief rod is coaxially provided with a first blind hole; the tail end of the thief rod is coaxially provided with a second blind hole; and the thief hole is isolated from the first and second blind holes. By the design of the blind holes in the thief rod, sealing effect of the seal rings is enhanced and service life of the seal rings is prolonged. By the adoption of the two seal rings with small wire diameter, pulling force or thrust during sampling can be reduced, and user experience is improved.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a quick sampler. 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 opening a third valve between ...
