Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As depicted in figs. 1 and 2, the self-enclosed compression test fixture in the present invention's specific embodiment comprises supporting seat, for installing tested valve; Hold down gag, for the tested valve that is tightly connected; Bearing plate, for installing hold down gag; Base, for installing supporting seat and bearing plate.
Hold down gag comprises cylinder end piece 5, cylinder block 6, cylinder axis 8 and cylinder head 7, cylinder end piece 7 is arranged on cylinder block 6, cylinder block 6 is connected with cylinder head 7, cylinder axis 8 is movably connected in the seal cavity that formed by cylinder block 6 and cylinder head 7, and cylinder axis 8 can axially move along the inwall of cylinder head 7.One air intake opening 51 is set at the center of cylinder end piece 5.A cylindrical channel 83 is established in cylinder axis 8 inside, outer setting one boss 81 of cylinder axis 8, and the diameter of boss 81 is less than or equal to the diameter of cylinder head 7 endoporus, the inwall clearance fit of boss 81 and cylinder head 7.Sealed by O RunddichtringO between cylinder axis 8 and cylinder block 6; Sealed by O RunddichtringO between cylinder axis 8 and cylinder head 7.
Cylinder block 6 is arranged first L-type passage be made up of the first Vertical Channel 61 and the first horizontal channel 62, the entrance of the first Vertical Channel 61 connects source of the gas, the inside of the outlet access cylinder head of the first horizontal channel 61.Cylinder head 7 is arranged second L-type passage be made up of the second Vertical Channel 71 and the second horizontal channel 72, the entrance of the second Vertical Channel 71 connects source of the gas, the inside of the outlet access cylinder head 7 of the second horizontal channel 72.
Hold down gag also comprises an outlet locating piece 12, the gas outlet end of tested valve 10 leans on outlet locating piece 12, sealed by O RunddichtringO between tested valve 10 and outlet locating piece 12, the air intake opening end of tested valve and the end contact of cylinder axis 8, sealed by O RunddichtringO between tested valve 10 and cylinder axis 8.
Base comprises bottom welding gusset 1, base plate 2 and symmetrically arranged movable triangle gusset 3, uses M16 tools for bolts ' pretension between movable triangle gusset 3 and bearing plate 4.
Supporting seat 11 is symmetrically arranged first V-type cushion block 111 and the second V-type cushion block 112.And distance between the first V-type cushion block 111 and the second V-type cushion block 112 is adjustable.
Tested valve in the present invention is gas pressure regulating valve, ball valve, safety shut-off valve.
The principle of work of self-enclosed compression test fixture of the present invention is as follows:
During clamping, on the first V-type cushion block 111 being positioned over supporting seat 11 by tested 10 and the second V-type cushion block 112, cylinder axis 8 in hold down gag and the air intake opening end contact of tested valve 10, the butt-end packing O type circle passed through between tested valve 10 and cylinder axis 8 seals; The gas outlet end of tested valve 10 leans on outlet locating piece 12, is sealed between tested valve 10 and outlet locating piece 12 by O RunddichtringO.The source of the gas of 0.8Mpa is filled with from the first Vertical Channel 61 entrance to pretension chamber, now butt-end packing O type circle crimp, form sealing ring, then be filled with test source of the gas from air intake opening 51 and carry out the test event of testing of dispatching from the factory, because the bearing area 81 surveying cylinder is greater than the bearing area 82 of butt-end packing O type circle, so snap-in force can change along with the change of test bleed pressure, realize the test of safety and stability.Be completed backward second Vertical Channel 71 to be filled with certain source of the gas the cylinder axis 8 in hold down gag can be allowed to be separated with tested valve 10, taking off tested valve 10 can carry out next round test.
The structural principle of the self-enclosed compression test fixture of the present invention relies on test source of the gas clamping plane sealing O type circle, and when leaking appears in structure, the pressure of whole system all can reduce together, substantially increases the security of test; Hold down gag utilizes pretension bleed pressure pretension butt-end packing O type circle, utilize the bearing area of cylinder and the pressure-bearing surface product moment of butt-end packing O type circle in test source of the gas cavity, realize test bleed pressure larger, the feature that snap-in force is also larger, reach self-enclosed effect, simple to operate and safe and reliable.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make various change and modification, therefore all equivalent technical schemes also belong to protection category of the present invention.
