The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-3, the present invention provides an embodiment: a joint for protecting a pressure gauge comprises a cover 1, wherein one end of the cover 1 is in threaded connection with the pressure gauge, and the other end of the cover 1 is in threaded connection with a joint body 3; the cap 1 is connected with the connector body 1 through threads, and the bag 5 is connected between the cap 1 and the connector body in a sealing manner; the outer surface of the bag 5 is rotatably connected with a gasket 2; rotation of the liner 2 on the bladder 5 is effected when the connector body 3 and the cap 1 are rotated relative to each other, thereby sealing the bladder 5 between the cap 1 and the connector body 3. The connector body 3 is in threaded connection with the cap 1, so that the gasket 2 and the bag 5 are pushed to be tightly connected between the cap 1 and the connector body 3; on guaranteeing that the device solves former problematic basis, through the effect of liner 2 for the phenomenon of tearing and fold can not take place for the terminal surface of bag 5, especially liner 2 can follow the terminal surface that connects the body 3 and take place the axial rotation, avoids connecting the body 3 and bag 5's direct contact, and then leads to bag 5 to take place the fold and the torn problem.

In order to facilitate the transmission of the pressure, a guide pillar 10 is further arranged at the center of the circle of the cover 1, and a through hole 9 for pressure transmission is arranged at the center of the guide pillar 10.

In order to facilitate the connection between the cover 1 and the joint body 3, the cover 1 is cylindrical, threads matched with the joint body 3 in a threaded manner are arranged on the outer surface of the cover 1, one end, far away from the joint body 3, of the cover 1 is in threaded connection with a pressure gauge through a connecting end 7, and the cross section of the connecting end 7 on the horizontal plane is hexagonal.

Further still be equipped with cavity 11 in the lid 3, wherein guide pillar 10 is located the centre of cavity 11, owing to set up cavity 11 and make the deflection of bag 5 bigger, and then reduce to lead to because of the reason of bag 5 self, slight deviation appears in the pressure measurement, consequently also further promotion manometer detection's precision.

In order to further solve the problem that the bag 5 is wrinkled and torn, a cushion trough 12 is further arranged on the end face, facing the connector body 3, of the cover 1, the bag 5 is limited to move continuously through the cushion trough 12, the end face of the bag 5 is further compacted through the arranged cushion trough 12, the bag 5 is prevented from moving eccentrically while the sealing degree is improved, and therefore the end face of the bag 5 is attached to the end face of the cushion trough 12 smoothly without wrinkling, and the phenomenon that the bag 5 is torn is avoided.

In order to further improve the sealing degree and avoid medium leakage, the bag 5 is also provided with a bag opening 6 which is attached to the material filling groove 12; wherein one side of liner 2 and sack 6 laminating, the another side with connect the body 3 laminating, because set up sack 6 and make when connecting body 3 and lid 1 extrusion, make sack 6 radially extend to enlarge the area of contact with the terminal surface of lid 1 and with the terminal surface that connects the body 3, thereby make the sealing performance of bag 5 obtain great promotion.

Because the connector body 3 is in threaded fit with the cover 1 through the connecting part 8, the connector body 3, the bag 5 and the cover 1 can be connected independently through the connecting part 8, and the problem of mutual interference caused by connection among the connector body 3, the bag 5 is axially distorted caused by rotation when the cover 1 is installed on the connector body 3, and the problem that detection deviation is large or sensitive parts of the pressure gauge are directly contacted with media caused by interference among the bag 5 is avoided when the pressure is transmitted by the bag 5.

In order to provide sufficient deformation space for the bladder 5 to ensure the problem of inaccurate detection caused by the deformation of the bladder 5 being blocked, the connector body 3 is provided with a cavity 13 for accommodating the bladder 5, and the cavity 13 is connected and communicated with the connecting portion 8.

Because the one end that the body 3 of piecing is kept away from lid 1 still is equipped with external screw thread post 4, install the device on the assigned position through external screw thread post 4 for the installation and the dismantlement of the device are simple and convenient.

Through the technical scheme, the utility model discloses easy dismounting still has, therefore make taking off and the installation simple and easy of bag 5, and then make the device both can prolong the life of whole equipment through changing cheap bag 5, simultaneously when the device is used for examining time measuring, it is simple and convenient, detachable bag 5, the repair time of the device has been shortened greatly, only need when detecting easy stifled medium pull down bag 5 and change new bag 5 can, bag 5 that pulls down simultaneously, it is washd, can also continue to use after the mediation, greatly reduced the maintenance cost of the device.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
