Abstract
The utility model discloses a bellows detection device, including detecting body and pressure testing pole, the pressure testing pole is worn out downwards to detect the body and be connected with hexagon nut, still is provided with the pressure testing pad between this hexagon nut and measuring body the bellows is established to the cover on the pressure testing pole, be provided with a O type circle between the upper end of bellows and the pressure testing pole, the lower extreme of bellows stretches into detect this and internal and seal up through seal gasket form airtight cavity between pressure testing pole and the bellows detect and still to set up threaded inlet port on the body, this screw thread inlet port with the cavity is linked together. It is showing the effect: simple structure, convenient operation, whether intact, avoided the bellows to assemble moreover and accomplished the shortcoming that could detect later its integrity if not only effectively having detected the bellows, practiced thrift artifical man -hour, has prevented the waste of material.
Description
Technical field
The utility model is related to valve body anti-leak detection technique field, is a kind of bellows detection device specifically.
Background technology
In many chemical industries, many media are toxic or severe corrosive, once leakage, will be to environment and life safety
Impact, so the leakage requirement to regulating valve is especially tight.Many valves can set ripple to realize that medium does not leak outside in valve
Pipe, to strengthen the protection to valve, prevents medium from leaking outside.
However, the processing of bellows valve and assembling process are complicated compared with common valve a lot, especially with the connection of valve rod, it is necessary to
Welding, technique is complex, and positioning requirements are higher.If cannot determine that whether bellows is intact, welds and assembles before welding
After test and find again, now doing over again easily causes bellows and valve rod is damaged.So, the inspection in advance to bellows is just especially weighed
It has been wanted that, and the detection of bellows exclusive structures shape bellows needs to be completed by other devices.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of bellows detection device, and the device exists
Detector integrity by before bellows assembling completion, can effectively prevent the waste of material.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of bellows detection device, it is critical only that：Including detection body and pressure testing bar, the pressure testing bar is passed downwards
Detection body is simultaneously connected with hex nut, pressure testing pad is additionally provided between the hex nut and detection body, in the pressure testing
Bellows is arranged on bar, the first O-ring is provided between the upper end of the bellows and pressure testing bar, the lower end of the bellows is stretched
Enter in the detection body and sealed by gasket seal, airtight cavity is formed between the pressure testing bar and bellows,
Thread inleting hole is further opened with the detection body, the thread inleting hole is connected with the cavity.
Further, the detection body includes the first pressure testing structure and the second pressure testing structure, the first pressure testing structure
It is connected by bolt and nut with the second pressure testing structure, boss, the sealing is provided with the center of the second pressure testing structure
Pad is supported on the boss with bellows, and the first pressure testing structure is located on the boss, in the second pressure testing knot
The thread inleting hole is opened up on structure.
Further, it is provided with the second O-ring between the second pressure testing structure and pressure testing bar.
Further, the upper end of the pressure testing bar is respectively arranged at two ends with the first limited step and the second limited step, described
First limited step is abutted with the upper end of the bellows, and second limited step is in the detection body.
Remarkable result of the present utility model is：Simple structure, easy to operate, not only whether effective detection bellows is complete
It is good, and avoiding bellows needs assembling to complete that the shortcoming of its integrity could be detected later, has saved labor hour, prevents
The waste of material.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of bellows detection device, including body 1 and pressure testing bar 2 are detected, the pressure testing bar 2 is worn downwards
Go out to detect body 1 and be connected with hex nut 3, pressure testing pad 4 is additionally provided between the hex nut 3 and detection body 1, in institute
State and bellows 5 is arranged on pressure testing bar 2, the first O-ring 6, the ripple are provided between the upper end of the bellows 5 and pressure testing bar 2
The lower end of line pipe 5 is stretched into the detection body 1 and is sealed by gasket seal 7, in the pressure testing bar 2 and bellows 5
Between form airtight cavity, be further opened with thread inleting hole 8 on the detection body 1, the thread inleting hole 8 and the cavity
It is connected.
Referring to accompanying drawing 1, the detection body 1 includes the first pressure testing structure 11 and the second pressure testing structure 12, first examination
Laminated structure 11 is connected with the second pressure testing structure 12 by bolt and nut, is provided with convex at the center of the second pressure testing structure 12
Platform 13, the gasket seal 7 is supported on the boss 13 with bellows 5, and the first pressure testing structure 11 is located at the boss
On 13, the thread inleting hole 8 is opened up in the second pressure testing structure 12.
By said structure, the modularization of device is not only realized, be easy to process and install and use, and by boss 13
With the cooperation between the first pressure testing structure 11, bellows 5 can be sealed more effectively by gasket seal 7, so as to protect
Hinder being smoothed out for bellows detection process.
In this example, in order to better ensure that the sealing of the present apparatus, between the second pressure testing structure 12 and pressure testing bar 2
It is provided with the second O-ring 9.
It can further be seen from figure 1 that the upper end of the pressure testing bar 2 is respectively arranged at two ends with the first limited step 21 and the second limit
Position step 22, first limited step 21 is abutted with the upper end of the bellows 5, and second limited step 22 is in the inspection
Survey in body 1.Pressure testing bar 2 can be carried out with the position of bellows 5 with the second limited step 22 by the first limited step 21
It is fixed, the stability and sealing adhered to during surveying are effectively guaranteed, so as to improve the confidence level of testing result.
The present apparatus is fixed on the first limited step 21 and detection body on pressure testing bar 2 when in use, first by bellows 5
Between 1, and repairing for ripple end is singly sealed by gasket seal 7, then by the injected media of the thread inleting hole 8,
It is to test bellows whether intact so that whether effective detection bellows intact, it is to avoid bellows need the assembling to complete with
The shortcoming of its integrity could be detected afterwards.
