Abstract
Provided is a circular port mechanical sealing or pressure measuring device. A mechanical sealing part of the circular port mechanical sealing or pressure measuring device is composed of an internal taper disc (1), a hollow screw rod (2) and a locking nut (4), the hollow screw rod (2) penetrates through the internal taper disc (1) and is fastened through the locking nut (4), a groove (3) is formed in the internal taper disc (1) along the circumference, and the groove (3) is sleeved with an O-shaped sealing ring (5). A pressure measuring part of the circular port mechanical sealing or pressure measuring device is connected with the hollow screw rod (2) through a threaded hole and is composed of a pressure meter (6) and a pressure regulation valve (7). The circular port mechanical sealing or pressure measuring device is a plugging device which is good in sealing effect, simple in operation, convenient to use and efficient and saves time.
Description
Technical field
The utility model belongs to the machine plugging apparatus structure technical field of pressure test.
Background technique
Existing pressure test blocking technology generally adopts: 1. welding; 2. silk mouthful shutoff; 3. bonding; 4. flange connects shutoff; 5. rigid obstruction etc.The sealability of these shutoff modes is also bad, and has some limitations, or will have certain precondition.
Summary of the invention: the object of the utility model device is just in order to fill up existing pressure test conditional defect in pipe plugging structure, and a kind of good sealing effect, simple to operate, easy to use, efficient, timesaving blocking device are provided.
The purpose of this utility model is achieved by the following technical solution.
Circular port mechanical seal or a pressure-detecting device, comprising: mechanical seal part and pressure measurement part; The utility model feature is, mechanical seal part consists of inner cone scale, cored screw, locking nut, and it is fastening that cored screw adopts locking nut to carry out through inner cone scale, on inner cone scale, along circumference, offers groove, is arranged with O RunddichtringO on groove; Pressure measurement part is connected with cored screw by tapped hole, and pressure measurement part consists of pressure gauge and pressure regulator valve.
The utility model is for sealing or the pressure measurement of the circular ports such as sterile gloves, drainage pipeline, floor drain.
The utility model carries out shutoff by interior expansion principle to pipe end, as long as have certain circularity and certain internal surface smoothness.As everyone knows, more modern pipelines are mostly plastic pipe and metallic conduit, can say that their circularity and internal surface smoothness foot have reached this and install required precondition, add that its sealing medium is colloid O type circle, so sealing effect is better, and can bearing certain pressure.
The beneficial effects of the utility model are, the utlity model has simple in structure, easy to operate, the advantage of good sealing effect, time-saving and efficiency.Its mechanical seal part can be done separately the port shutoff of different tube diameters, has very strong applicability.Sealing medium used is colloid O type circle, therefore sealing effect is better.Can be widely used in machinery, pharmaceutical industry.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
See Fig. 1, a kind of circular port mechanical seal pressure-detecting device, comprising: mechanical seal part and pressure measurement part; The utility model feature is, mechanical seal part consists of inner cone scale 1, cored screw 2, locking nut 4, it is fastening that cored screw 2 adopts locking nut 4 to carry out through inner cone scale 1, on inner cone scale 1, along circumference, offers groove 3, is arranged with O RunddichtringO 5 on groove 3; Pressure measurement part is connected with cored screw 2 by tapped hole, and pressure measurement part consists of pressure gauge 6 and pressure regulator valve 7.
The utility model is for sealing or the pressure measurement of the circular ports such as sterile gloves, drainage pipeline, floor drain.
On the groove 3 that the utility model inner cone scale 1 is offered, play holder colloid O RunddichtringO 5; By the locking nut 4 on cored screw 2, screw, inner cone scale and groove are done motion to axial, thereby push O RunddichtringO, make its diameter become large and tube wall extruding, thereby play seal action.
The utility model can be widely used in machinery, pharmaceutical industry.As the 1. bottling department A level gloves leak detection of pharmaceutical industry; 2. clean area floor drain shutoff; 3. pipe end shutoff is filled hydrogen brazing and is connect; 4. make adjustable piston etc. by oneself.
Claims (1)
1. circular port mechanical seal or a pressure-detecting device, comprise mechanical seal part and pressure measurement part; It is characterized in that, mechanical seal part consists of inner cone scale (1), cored screw (2), locking nut (4), cored screw (2) adopts locking nut (4) to carry out fastening through inner cone scale (1), at inner cone scale (1), above along circumference, offer groove dish (3), at groove dish (3) termination point casing, be provided with O RunddichtringO (5); Pressure measurement part is connected with cored screw (2) by tapped hole, and pressure measurement part consists of pressure gauge (6) and pressure regulator valve (7).
