Description

Technical Field

[0001] The utility model relates to the technical field of pressure detectors, in particular to a pipeline internal pressure detector. Background Art

[0002] A hose is a closed, annular object that can be used to store or transfer gas, liquid, or even powdered materials. To test the sealing performance of a hose, it is necessary to perform a pressure test on the hose to prevent it from breaking due to the pressure. Therefore, a tester is often used to perform an internal pressure test on a section of the hose.

[0003] However, ordinary detectors are only connected to the pipe to be tested through metal pipe mouths and flanges, which have gaps and are difficult to maintain the connection between the pipes. Gas, powder, and liquid may overflow under the pressure, easily contaminating the surrounding environment and the workers' hands, which is very inconvenient.

[0004] Now, a new type of hose internal pressure detector is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a pipeline internal pressure detector to solve the problem of poor sealing performance mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipeline internal pressure detector, comprising a pressure gauge and a screen, a screen is installed above the front end of the pressure gauge, a connecting pipe 1 is fixed to the top of the pressure gauge, and the top of the connecting pipe 1 is fixedly connected to a hose, a connecting pipe 2 is fixed to the bottom of the right side of the hose, and the bottom of the connecting pipe 2 is movably connected to a shift rod, an assembly pipe is installed at the bottom of the shift rod, and a sleeve block is welded below the assembly pipe, a notch is provided between the upper part of the inside of the sleeve block and the assembly pipe, a rubber sleeve is fixed around the bottom of the sleeve block, and connecting pieces are respectively fixed on both sides of the top of the rubber sleeve, and adhesive hook pieces are fixed on the sides of the connecting piece, fluff strips are respectively fixed on the upper sides of the outside of the sleeve block, and an inner ring is fixed around the inside of the sleeve block.

[0007] Preferably, the hook sheet has the same area as the fluff strip, and the hook sheet is attached to the outside of the fluff strip.

[0008] Preferably, the notch is embedded between the assembly tube and the sleeve block, and the notch, the rubber sleeve, the inner ring and the assembly tube are arranged in concentric circles.

[0009] Preferably, a ferrule is respectively sleeved on both sides of the outer side of the connecting tube, and an arc-shaped sleeve is longitudinally fixed to the inner wall of the ferrule, a positioning piece is fixed to the surface of the front end of the ferrule, and a screw hole is transversely provided at the center of the positioning piece, and bolts are transversely assembled between the screw holes, and a rotary block is movably connected to the side of the outer side of the ferrule, and a shell is fixed on the outer side of the rotary block, elastic shafts are respectively installed on both sides of the inside of the shell, and a reel is installed at the center between the elastic shafts, a connecting rope is wound around the outside of the reel, and a circular hole is provided at the top end of the rear of the shell.

[0010] Preferably, both sides of the connecting rope are respectively embedded in the circular holes, and both sides of the connecting rope move back and forth along the circular holes respectively.

[0011] Preferably, the outer wall of the bolt matches the screw hole, and the bolt can tighten the positioning piece at the front end of the ferrule.

[0012] Preferably, the right side of the assembly tube is movably connected to a right limiting rod, and the left side of the assembly tube is movably connected to a left limiting rod, and the right limiting rod and the left limiting rod can be overlapped on the surface of the shifting rod.

[0013] Preferably, the right limiting rod and the left limiting rod have the same length, and the right limiting rod and the left limiting rod can be longitudinally rotated on both sides of the assembly tube respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the hose internal pressure detector not only strengthens the connection sealing between the instrument and the hose body, realizes the collection of the hose, but also realizes the limit lever;

[0015] (1) An assembly tube is installed at the bottom of the lever, and a rubber cover is wrapped around the outside of the assembly tube at the lower right corner. The connecting piece on the top of the rubber cover can be fixed to the velvet strip through an adhesive hook. It can be rolled up when not in use and put down when needed. When the tube body is inserted into the sleeve block, it contacts the inner ring. Then the connecting piece is put down and wrapped around the outer tube body for sealing. This prevents the assembly from being dispersed when pressure is applied to the other end of the tube body, which is beneficial to keep the pressure inside the detector from dropping.

[0016] (2) By wrapping a connecting rope around the outside of the reel, the ferrules wrapped around the outside of the connecting pipes 1 and 2 can be assembled by bolts. The threaded bolts can be screwed into the screw holes to tighten the positioning pieces. The direction of the circular hole of the shell can be adjusted by turning the rotary block. The reel installed on the internal elastic shaft can tighten the connecting rope from both sides to adjust the distance between the ports on both sides of the hose, so as to avoid the hose from opening too much and occupying too much area. The left and right pipe opening positions of the hose can also be adjusted according to the stretching requirements.

[0017] (3) A right limit rod is movably connected to the right side of the assembly tube, and a left limit rod is movably connected to the left side of the assembly tube. The lever at the bottom of the second connecting tube can control the opening and closing of the assembly tube, so that the tube body fixed by the assembly tube can introduce the pressure to be tested to the pressure gauge for the instrument to analyze and detect the tube body. The right limit rod and the left limit rod can also be locked according to the different fixed positions of the lever to prevent the lever from rotating and preventing the lever from shaking and affecting the release and closing of pressure.
