Description

A kind of manometer leak-proof device
Technical field
The present invention relates to manometer technical field, more particularly to a kind of manometer leak-proof device.
Background technology
Pressure gauge passes through the sensing element in table(Bourdon tube, bellows, bellows)Elastic deformation, by table movement turn The deformation is conducted to pointer by converting mechanism, so as to cause indicators turn to show pressure.By taking Bourdon pressure gauge as an example, Bourdon tube Sensing element is a circumflexion, the elastic C-shaped pipes of the aobvious ellipse of sectional area, and the pressure of measured medium acts on the interior of Bourdon tube Side, such Bourdon tube oval cross section can tend to circular section.Due to the micro-strain of Bourdon tube, certain Zernike annular polynomial is formed, the ring Stress makes Bourdon tube stretch out, and because elastic bowden tube head is not fixed, it can produce slight deformation, and it is deformed big The small pressure size depending on measured medium.The deformation of Bourdon tube is directly shown the pressure of measured medium by movement by pointer Power.
The input of traditional manometer is the sealing simply by threaded connection at the detection mouth of equipment It is ineffective, so as to influenceing the detection of manometer, while it is not easy to control to adjust the input and detection mouth of manometer It is logical to close, influence the use of manometer.In order to solve the above problems, we have proposed a kind of manometer leak-proof device.
The content of the invention
The invention aims to solve the input of existing manometer simply to install simply by threaded connection At the detection mouth of equipment, sealing effectiveness is bad, so as to influence the detection of manometer, while is not easy to control to adjust Instrument for Pressure The input of table and the logical of detection mouth close, and influence the problem of manometer uses, and a kind of manometer proposed is with anti-neglected loading Put.
To achieve these goals, present invention employs following technical scheme:
A kind of manometer leak-proof device, including the first communicating pipe being connected with manometer body, first communicating pipe Threaded one end away from manometer body was socketed with for the second communicating pipe, and second communicating pipe is close to one end of the first communicating pipe Screw thread is socketed with locking nut, and upper fixed cover was connected to and corresponding with locking nut compressed ring, the locking first communicating pipe Nut is fixedly connected with the first gasket seal, the side of first gasket seal away from locking nut close to the one end for compressing ring Offseted with compressing ring, be provided with mounting blocks in second communicating pipe, the side of the mounting blocks is provided with mounting groove, the mounting groove Inner bottom part ball sealer is connected with by spring, end of the ball sealer away from spring through mounting groove notch and with first Communicating pipe, the madial wall away from manometer one end offseted, and the both sides of the mounting blocks are by rotating shaft and the second communicating pipe Side wall is rotatablely connected, and one of them one end of the rotating shaft away from mounting blocks is run through the madial wall of the second communicating pipe and is fixedly connected There is adjustment disk.
Preferably, the adjustment disk is provided with retaining ring close to the side of the second communicating pipe, and the retaining ring screw thread is socketed in In rotating shaft, side of the retaining ring away from adjustment disk is provided with the second gasket seal, and second gasket seal is away from retaining ring Side and the lateral wall of the second communicating pipe offset.
Preferably, second gasket seal close to the side of the second communicating pipe be provided with second communicating pipe lateral wall it is corresponding Arc contact groove.
Preferably, it is provided with the madial wall of second gasket seal around multiple accommodating grooves are provided with the accommodating groove Ball, end of the ball away from accommodating groove madial wall is through accommodating groove notch and and shaft contacts.
Preferably, second communicating pipe close to first communicating pipe one end outboard sidewalls on be arranged with raw material band.
Preferably, the mounting blocks are in the form of annular discs, and its diameter is less than the internal diameter of the second communicating pipe.
In the present invention, the detection mouth seamless welding of the second communicating pipe and equipment, while pass through the first communicating pipe and locking screw Female threaded connection with the second communicating pipe, secondary thread seal is carried out, improve sealing property, turn locking nut so that first Gasket seal offsets with compressing ring, further improves sealing property, by rotating adjustment disk, so that rotating shaft drives mounting blocks Rotate, the direction deflection of mounting groove notch in rotation process, so that ball sealer and the first madial wall for connecting pipe port Depart from, and then manometer input connects with equipment detection mouth, when mounting groove notch and the first position pair for connecting pipe port At once, because the elastic force of spring acts on so that the madial wall that ball sealer connects pipe port with first offsets, so as to which manometer is defeated Enter end to close with equipment detection mouth.The present invention improves sealing property by secondary thread seal, while by turning locking screw It is female so that the first gasket seal offsets with compressing ring, further improves sealing property, the input of manometer and detection mouth Logical close is easy to control, consequently facilitating the use of manometer.
