Embodiment Construction

[0008] The present invention will be described in further detail below. see figure 2 , a device for checking the correctness of the assembly of the sealing ring and the protective ring on the valve sleeve, characterized in that: it is composed of a V-shaped block 1 made of transparent material and a comparison card 2; the cross-sectional profile of the V-shaped block 1 is rectangular, On the upper surface of the V-shaped block 1, there is a V-shaped groove 3 penetrating along the length direction of the V-shaped block 1. The angle α between the two groove walls of the V-shaped groove 3 is α=60°~120°. At least one side is provided with a comparison card placement slot that runs through the length direction of the V-shaped block 1 and has a rectangular cross section. The comparison card 2 is placed in the comparison card placement slot; A 1:1 photo of the valve sleeve with the sealing ring and the protective ring.

[0009] In order to facilitate the positioning of the valve s...

Abstract

The invention belongs to the technical field of hydraulic detection, and relates to a checking device for assembly correctness of seal rings and protective rings on valve bushes. The checking device is characterized by being composed of a V-shaped block (1) made of transparent material and a comparison card (2). According to the checking device, mistaken assembly or neglected assembly can be conveniently found, the assembly quality is guaranteed, and the assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic detection, and relates to a device for checking the correctness of assembly of a sealing ring and a protection ring on a valve sleeve. Background technique [0002] see figure 1 The schematic diagram of the structure of a certain type of valve sleeve is shown. The sealing groove of the valve sleeve 4 in the hydraulic product will be installed with a protection ring 6 made of fluoroplastic and several sealing rings 5 ​​of different materials. The sealing rings 5 ​​of different materials generally have different characteristics. The relative position of the protection ring 6 and the sealing ring 5 has the following situations: the single protection ring 6 is located on the left side of the sealing ring 5, the single protection ring 6 is located on the right side of the sealing ring 5, and the double protection ring 6 is located on the sealing ring 5 sides. In the actual assembly process, there a...
