Abstract
The utility model discloses an airtightness pressure measuring device for a center line type butterfly valve. The airtightness pressure measuring device comprises a tray and an air inlet pipe. The tray is a sealed cavity, the center of the top end of the tray is provided with an air outlet, the air inlet pipe is connected on one side wall of the tray, and a tray limit projection matched with the inner diameter of a valve seat of the center line type butterfly valve in shape is arranged on the upper end face of the tray. An air inlet of the air inlet pipe is connected with an air pump, and the air inlet pipe is communicated with an exhaust pipe. A first valve is arranged on the air inlet pipe between the air inlet and the exhaust pipe, and a barometer is arranged on the exhaust pipe between the air inlet pipe and a second valve. Compared with the prior art, the airtightness pressure measuring device is simple to operate, and requires no extra training on operators and increase of production cost; the airtightness pressure measuring device is simple in structure, convenient to manufacture and conducive to popularization and application in the industry; the measuring device is better in measurement by arranging the tray limit projection.
Description
Technical field
The utility model belongs to centre-pivoted butterfly valve processing technique field, relates in particular to a kind of centre-pivoted butterfly valve sealing barometric surveying equipment.
Background technology
Centre-pivoted butterfly valve is a kind of parts that are used for realizing pipe system break-make and flow control, in many fields such as oil, chemical industry, metallurgy, water power, obtains applying very widely.The architectural feature of centre-pivoted butterfly valve is that rotating shaft core, butterfly plate center, body center are on same position.
In the process segment that centre-pivoted butterfly valve performing leak test is manufactured as centre-pivoted butterfly valve, after performing leak test is qualified, product just can dispatch from the factory.At present, the standard that the processing and manufacturing of centre-pivoted butterfly valve leak tightness testing equipment is ununified, how this effectively carries out centre-pivoted butterfly valve performing leak test to enterprise and has proposed a difficult problem.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, the good centre-pivoted butterfly valve sealing of result of use barometric surveying equipment, to solve the problem of effectively carrying out centre-pivoted butterfly valve performing leak test existing in prior art.
For realizing the purpose of this utility model, the utility model provides a kind of centre-pivoted butterfly valve sealing barometric surveying equipment, described measuring equipment comprises: pallet, draft tube, described pallet is seal chamber, its centre, top is provided with gas outlet, on one sidewall, be connected with draft tube, its upper surface is provided with the pallet spacing preiection matching with described centre-pivoted butterfly valve valve seat bore shape; The air intake opening of described draft tube is connected with air pump, and described draft tube is also connected with a bleeder pipe; In the described draft tube between described air intake opening and described bleeder pipe, be provided with the first valve, on the described bleeder pipe between described draft tube and described the second valve, be provided with rain glass.
The beneficial effects of the utility model are, compared with the prior art, it is simple to operate, to operating personnel without additionally training, without increasing production cost; Simple in structure, easy to make, be conducive to industrially apply; Be provided with pallet spacing preiection, make measurement effect better.

In figure, 1-pallet, 11-gas outlet, 12-pallet spacing preiection, 2-air intake opening, 3-the first valve, 4-rain glass, 5-relief port, 6-the second valve.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model provides a kind of centre-pivoted butterfly valve sealing barometric surveying equipment, described measuring equipment comprises: pallet, draft tube, described pallet is seal chamber, its centre, top is provided with gas outlet, on one sidewall, be connected with draft tube, its upper surface is provided with the pallet spacing preiection matching with described centre-pivoted butterfly valve valve seat bore shape; The air intake opening of described draft tube is connected with air pump, and described draft tube is also connected with a bleeder pipe; In the described draft tube between described air intake opening and described bleeder pipe, be provided with the first valve, on the described bleeder pipe between described draft tube and described the second valve, be provided with rain glass.
When use, by the flap closure of centre-pivoted butterfly valve, lie on pallet, valve seat is just in time stuck on described pallet spacing preiection, such structural design, play sealing function, after placing, pallet band valve seat has been placed under the weight of pressing machine or specified weight, open the first valve, close the second valve, draft tube connects air pump, in pallet cavity, inflates, watch rain glass, whether inflation until reach preset air pressure value, stops inflation, watch rain glass to change, if nothing, sealing is out of question, if had, sealing has problem.After testing, open the second valve, venting, after having exitted, just can take off centre-pivoted butterfly valve from pallet.
The beneficial effects of the utility model are, compared with the prior art, it is simple to operate, to operating personnel without additionally training, without increasing production cost; Simple in structure, easy to make, be conducive to industrially apply; Be provided with pallet spacing preiection, make measurement effect better.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
