Abstract

A kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve, by stiff end and sliding-end on measurement section is set, the slope suitable with U-shaped sealing pair rim inner diameter inclined-plane is provided with inside measurement section, because gradient inside measurement section adapts to sealing pair internal diameter, add the accuracy of measurement, and the second scale of mark measurement section width, only vernier caliper reading need be added measurement section width during calculating, namely can be regarded as to obtain sealing pair internal diameter size, preferably the O-ring seal size of production is added with meticulous measurement to machine, substantially increase the demand that the interchangeability of O-ring seal and accuracy better meet market.

Description

A kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve
Technical field
The utility model relates to valve fields of measurement, is specifically related to a kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve.
Background technology
Along with the develop rapidly of modern industrial technology, three eccentric metal sealed butterfly valve is widely used in pipe control system, and particularly other control the implacable large diameter pipeline control system of class.Some are needed to the occasion of frequent switch, the sealing reliability of valve can be particularly important, and coordinate excellent sealing pair to be the key point determining its life-span and quality.What current most domestic producer manufactured mostly is valve body and butterfly plate list distribution type, its closure size value is many to be obtained by interior card rough measure, fitness is corrected finally by singly joining correction bore hole, but the size finally measured of such design often precision is not high, particularly U-shaped sealing pair has inclined-plane due to its interior shape, and often measuring accuracy is inaccurate to adopt traditional survey instrument.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve.
The technical solution that the utility model adopts is: a kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve, comprise main scale and sliding-end, described main scale is provided with the first scale, described sliding-end is provided with vernier, described main scale is provided with stiff end, described stiff end and sliding-end are provided with measuring head, described measuring head is provided with the measurement section for measuring U-shaped sealing pair rim inner diameter size, first slope suitable with U-shaped sealing pair rim inner diameter inclined-plane is provided with inside described measurement section, described measurement section also comprises front end and is also provided with the first boss for joining with the clamping of U-shaped sealing pair interior grooves, the first described boss comprises the second slope with U-shaped sealing pair interior grooves adaptation.
The first described boss is provided with the second boss for fixing U-shaped sealing pair.
Described measurement section is also provided with the second scale of mark measurement section width.
Also clamping section is provided with inside described measurement section.
Described sliding-end and vernier are welded to connect.
Described main scale and sliding-end surface scribble corrosion-inhibiting coating.
The beneficial effects of the utility model are: the utility model provides a kind of special vernier caliper measuring the U-shaped sealing pair internal diameter size of butterfly valve, by stiff end and sliding-end on measurement section is set, the slope suitable with U-shaped sealing pair rim inner diameter inclined-plane is provided with inside measurement section, because gradient inside measurement section adapts to sealing pair internal diameter, add the accuracy of measurement, and the second scale of mark measurement section width, only vernier caliper reading need be added measurement section width during calculating, namely can be regarded as to obtain sealing pair internal diameter size, preferably the O-ring seal size of production is added with meticulous measurement to machine, substantially increase the demand that the interchangeability of O-ring seal and accuracy better meet market.
