Embodiment Construction

[0033] 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.

[0034] 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.

[0035] Such as figure 2...

Abstract

The invention relates to a design method of a quick sampler used in a boiler, which comprises providing a base body and a sampling rod, so that the sampling rod and the base body can be slidingly or rotatably matched in a closed manner; it is characterized in that the head of the sliding cavity of the base body is close to the sampling cavity. Set the first sealing ring, and set the second and third sealing rings at the end of the sliding cavity of the base body near the sampling cavity, so that the axial distance between the second and third sealing rings is greater than the width of the sampling hole, and the first sealing ring The sampling cavity is isolated from the sliding cavity, and the sampling cavity is isolated from the outside atmosphere through the second and third sealing rings. A first blind hole is set at the head end of the sampling rod, and a second blind hole is set at the tail end of the sampling rod, so that the sampling hole is isolated from the first blind hole and the second blind hole, and the first blind hole and the second blind hole are separated by the ventilation channel. Blind vias are connected. The blind hole design on the sampling rod improves the sealing effect and service life of the sealing ring. The use of two small diameter sealing rings can reduce the pulling force or pushing force during sampling and improve the sampling speed.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a design method of 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 t...
