Embodiment 1

[0051] 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.

[0052] like 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 7 ), turn the sampling rod 2 (see image 3 and 8 ), 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.

[0053] like figure 2...

Embodiment 2

[0079] like Figure 14-16 As shown, the limiter 3 is provided with two limit pins 301 and one extension spring 302, the extension spring 302 and the limit pin 301 are coaxially arranged, the two limit pins 301 are placed oppositely, and the extension spring 302 makes The shoulder end surface 303 of the limiting pin 301 cooperates with the outer cylindrical surface of the sampling rod 2 , and the shoulder cylindrical surface 304 of the limiting pin 301 cooperates with the stepped surface 111 of the base 102 . Such setting realizes the friendliness of assembly. First, turn the two mounting holes at the head end of the sampling rod 2 to a horizontal position, and then conveniently install the two limit pins 301 from the outer cylindrical surface of the sampling rod 2 into corresponding positions. Then one end of the extension spring 302 is hooked to the stop pin 301, and then the extension spring 302 is elongated by a certain amount and hooked to another stop pin 301. After assem...

Embodiment 3

[0081] like Figure 12 As shown, the number of the second through holes 104 of the base 102 in the first embodiment is set to 1, and the diameter of the second through holes 104 is larger than the diameter of the first through holes 103. A certain space is formed on both sides, and such a space serves as a flow area 111 , which facilitates the flow of the liquid in the second through hole 104 , thereby renewing the liquid around the sampling hole 202 .

Abstract

The invention relates to a design method for a fast sampler used on a boiler. The fast sampler comprises a sampling rod in closed sliding or running fit with a base body, wherein a cover is arranged on the base body and is detachably matched with a base in a closed manner, an accommodating cavity for accommodating the sampling rod is coaxially formed in the cover, and when the sampling rod is in an insertion position, the joint of the cover and the base is located between a first groove and a limit piece; a first counter bore is formed in the head part of the base, the diameter of the first counter bore is larger than that of a first through hole and a stepped surface is formed; the limit piece is detachably arranged at the head part of the sampling rod, and when the limit piece is matched with the stepped surface of the base, a sampling hole is formed outside the base. The base body is dismounted into the base and the cover, the axial processing length of the base is reduced, and the processing difficulty is reduced accordingly; the joint is arranged between the first groove and the limit piece, and the limit piece is assembled conveniently; the limit piece is arranged at the head part of the sampling rod, the axial dimensions of the base and the sampling rods are both reduced accordingly, and materials are saved.

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...
