Description

Safety valve experiment clamping tooling
Technical field
The utility model relates to a kind of frock of carrying out testing for clamping safety valve.
Background technology
The effect of safety valve test clamping tooling be entrapment valve on test-bed, simulated condition is carried out take-off to safety valve, is returned seat test.Requirement clamping is firm, and sealing is not tightly leaked, and has certain against shock function.
Existing safety valve test clamping tooling roughly has two kinds of installation way: to be relief valve connection with testing equipment interface all adopt a kind of mode that engagement thread docks to be connected tests; Another kind of mode is that relief valve connection welds anti-flange, testing equipment adopts flange, uses bolt to connect and tests.
All there is unicity limitation in existing safety valve test clamping tooling.And thread connecting mode frock requires that thread seal difficulty of processing is large; Flange connection frock requires that safety valve welds anti-flange, organizes the defect that the process-cycle is long, cost is high.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of safety valve to test clamping tooling, and convenient mounting and clamping, applicability is strong.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of safety valve experiment clamping tooling, comprises one for the base of place work piece, it is characterized in that: described base is provided with some Compact Mounts and vertical stopping means; Described Compact Mounts comprises the positive stop be arranged on base, described positive stop has the screw of level, is installed with the Limit screw coordinated with screw in screw; Described vertical stopping means comprises a briquetting, vertically puts into the tommyhead bolt of base T-slot, is vertically placed on base and rotatable adjusting bolt; Described briquetting is threaded with adjusting bolt, and is placed on tommyhead bolt; Tommyhead bolt is positioned at above briquetting and is also provided with a clamp nut.
Improve as one, described Compact Mounts and vertical stopping means are three groups, and press the distribution of base even circumferential, and interval is installed.Compact Mounts and vertical stopping means are uniformly distributed, the workpiece uniform force being.
Improve as one, described base bottom be also provided with one with the dowel screw of equipment connection.Convenience and equipment connection.
Improve as one, described Limit screw front end is provided with the spacing head with absorption surface position form fit.The contact point of Compact Mounts and workpiece is increased, improves limit effect.
Usefulness of the present utility model is: the utility model highly versatile, and clamping is firm, reliable, simple, handy.Avoid different bore safety valve and need process different screw thread or flange, greatly save frock materials and processing cost.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 of the present utility modelly faces sectional structure schematic diagram.
Mark in figure: 1 nut, 2 experiment safety valves, 4 positive stops, 5 bases, 6 Limit screws, 8 spacing heads, 9 clamp nuts, 12 briquettings, 13 adjusting bolts, 14T shape bolt, 15 studs
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises one for placing the base 5 of experiment safety valve 2, be also provided with bottom base 5 one with the stud 15 of equipment connection.Described base 5 is provided with some Compact Mounts and vertical stopping means; Described Compact Mounts comprises by the fastening positive stop 4 be arranged on base 5 of nut 1, described positive stop 4 has the screw of level, is installed with the Limit screw 6 coordinated with screw in screw; Limit screw 6 front end is provided with spacing 8 with workpiece 2 contact position form fit.Described vertical stopping means comprises a briquetting 12, vertically puts into the tommyhead bolt 14 of base 5T shape groove, is vertically placed on base 5 and rotatable adjusting bolt 13; Described briquetting 12 is threaded with adjusting bolt 13, and is placed on tommyhead bolt 14; Tommyhead bolt 14 is positioned at above briquetting 12 and is also provided with a clamp nut 9.Compact Mounts and vertical stopping means are preferably three groups, and press the distribution of base 5 even circumferential, and interval is installed.
When using, experiment safety valve 2 is placed on base 5, utilizes Limit screw to adjust spacing head and prevent the horizontal play of experiment safety valve 2, utilize briquetting 12 to prevent experiment safety valve about 2 play.Turn Limit screw 6 and adjusting bolt 13 can regulate the position of Limit screw 6 and briquetting 12, in order to be applicable to the experiment safety valve 2 of different model.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
