Embodiment 1

[0044] This embodiment provides a detection method for a gate valve gate, which includes the following steps: take a standard gate, place it on a wedge-shaped block 1 with a slope 11 of a chute 4, and make the top of the standard gate The sealing surface is kept horizontal, and the sum of the height of the wedge block 1 and the thickness of the standard gate is equal to the standard thickness (H 标准 ); Get a ram 2 to be tested, place it on the inclined plane 11 of the wedge block 1, measure the height of its small head end B point (H B ); according to H B with H 标准 Determine the relationship between the thickness dimension (b) of the gate plate 2 to be tested and the thickness dimension of the standard gate plate.

[0045] The wedge block 1 provided by the present invention has a standard size. When the standard gate is placed on the wedge block 1, one sealing surface of the standard gate will fit the inclined surface 11 of the wedge block 1, so that the other seal of the sta...

Embodiment 2

[0055] In this embodiment, the distance measuring device includes a dial gauge 5 for measuring H A 、H B and H 标准 Take measurements. The structure of the dial indicator 5 is relatively simple, the transmission mechanism is a gear train, the outer dimension is small, the weight is light, and it is convenient for dimension measurement.

[0056] As a variation, other tools can be used to measure the size, as long as they can play the role of size measurement.

[0057] At the same time, the measuring device also includes a gauge base 6, through which the dial indicator 5 can be measured at different positions, which has great flexibility.

[0058] Simultaneously, on the basis of present embodiment, also can be provided with a standard sample block 7, the height of this standard sample block 7 is equal to the height of the whole body of the two after the standard flashboard is placed on the wedge block 1, can save by the standard sample block 7 time and improve detection efficie...

Embodiment 3

[0062] In this example, if Figure 5As shown, a kind of through-gauge slider 3 is provided, including: a detection end 31, which is connected inside the guide groove 21 of the gate to be tested 2 or a standard gate; a sliding end 32, which is installed on the In the chute 4 , the detection end 31 and the sliding end 32 are parallel to each other, and the distance between them is equal to the distance between the chute 4 and the guide groove 21 when the standard flashboard is placed on the wedge block 1 . The connecting block 33 , the detecting end 31 and the sliding end 32 are connected to the connecting block 33 , and the detecting end 31 and / or the sliding end 32 can move on the connecting block 33 .

[0063] Place the standard ram on the wedge block 1, keep the top sealing surface of the standard ram horizontal, put the through-gauge slider 3 into the guide groove 21 and the chute 4, and adjust the detection end 31 at this time And / or the sliding end 32 makes it move on th...

Abstract

The invention relates to the technical field of a gate valve and particularly relates to a gate valve flashboard detection method. According to the method, qualitative analysis on a flashboard is carried out in a quantitative mode; after detection, if a display dimension is overlarge, the dimension of the processed flashboard is adjusted to be smaller during the next processing process; values are employed to replace a visual detection method, higher accuracy and relatively high efficiency are realized, and detection on batches of flashboards is convenient. Through the method, a problem of over-cumbersomeness for requiring assemblying a flashboard in a valve body during a width detection process of a guiding groove of the flashboard in the prior art can be effectively solved through a Go-gauge sliding block.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to a detection method for gate valve gates. Background technique [0002] As a common fluid switch, the gate valve includes a valve body and a gate plate. There are symmetrical seat ring holes processed inside the valve body, and seat rings are welded on the seat ring holes. When the gate valve is closed, the gate plate and the seat ring fit together to form a seal. surface, thus completing the sealing action. [0003] In the prior art, the wedge gate valve adopts a V-shaped wedge gate, and a V-shaped valve seat matched with the gate is arranged in the passage of the valve body. For the gate, the wedge angle of the two sealing surfaces must be consistent with the wedge angle of the corresponding valve body seat ring hole. The two sides corresponding to the gate and the seat ring are called sealing surfaces, such as figure 2 As shown, the topmost point of the sealing surface i...
