Description

Valve torque testing device

Technical Field

The utility model relates to a valve torque test technical field especially relates to a valve torque testing arrangement.

Background

Valves are mechanical products that are subjected to internal pressure and must therefore have sufficient strength and rigidity to ensure long-term use without cracking or deformation. The opening and closing force and the opening and closing torque refer to the force or torque that must be applied to open or close the valve. The valve opening and closing torque is an important performance index for reflecting the comprehensive level of the valve. All current valve detection devices display the test strength and the sealing performance by a pressure gauge according to relevant national standards. For this purpose, corresponding test devices have been developed for testing the torque of the valve.

When the torque test of the valve is carried out, the torque test experiment table is required to be connected with the valve shaft of the valve, a bridge is formed between the torque test experiment table and the valve shaft, and the torque force of the valve is measured by applying force to rotate the valve shaft through the torque test experiment table. The existing tool for torque test connection is of a single type, one tool can only be used for one product and cannot meet the connection requirements of valve shafts of various specifications, and therefore improvement is needed.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 to 5, a valve torque testing device includes a valve torque testing fixture for connecting one end 101 of a valve shaft of a tested valve 100 and one end of a connecting rod 4, the valve torque testing fixture has a tool connecting end 1 and a valve shaft connecting portion 2 of the valve, the valve shaft connecting portion is a rectangular body and has a first positioning hole 21 adapted to the shape of a first valve shaft, and the valve torque testing device further includes at least one positioning block 3 capable of being embedded into the positioning hole and having a second positioning hole 32 adapted to the shape of a second valve shaft. Of course, more positioning blocks may be nested, such as two or more positioning blocks, or even more positioning blocks, which are not limited to the positioning blocks shown in this application and the drawings, and for example, a positioning block is further embedded in a positioning block, so that connection that can adapt to valve shafts of more models can be achieved.

Of course, the size or model of the second positioning hole 32 can be made into various specifications, so that the valve shaft connection which can adapt to various specifications can be realized.

The first positioning hole 21 is a regular multi-shape hole, and can be inserted into a shaft head of the rectangular body of the first valve shaft or into the positioning block 3. The outer peripheral surface of the positioning block is a regular polygon structure 31, and the first positioning hole is a regular polygon hole corresponding to the regular polygon structure. The second positioning hole is a rectangular hole, and a shaft head of the rectangular body of the second valve shaft is inserted into the second positioning hole. The tool connecting end is a cylinder, the connecting rod is a tubular body, and the cylinder is connected with the valve torque testing tool in the tubular body through insertion. Wherein, a pull ring 5 is arranged on the outer wall of the connecting rod at a position close to the other end. Through setting up the pull ring, can connect the stay cord of transmission effort through the pull ring, through the taut stay cord of moment of torsion laboratory bench equipment to the effort that provides the moment of torsion test and use, give connecting rod 4 one for the rotatory effort of valve shaft, through detecting the tensile size of stay cord, obtain moment of torsion test data, thereby realize testing the moment of torsion of valve under the user state as shown in fig. 2.
