Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this instructions.
Refer to Fig. 1 and Fig. 3.Notice, appended graphic the illustrated structure of this instructions, ratio, size etc., equal contents in order to coordinate instructions to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this instructions, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 1 to Figure 3, a kind of sanitary pneumatic valve stem seal device for fast detecting, comprise pneumatic means 1, water inlet interface 4, water inlet interface 4 is for being connected to the detection position of pneumatic valve rod 7, water inlet interface 4 has two, each water inlet interface 4 is provided with hickey end, two positions detecting for being closely connected to the need of pneumatic valve rod 7.Water inlet interface 4 is provided with a tensimeter 5, can need accurate adjustment test pressure according to test, and the position that water inlet one end of interface 4 and the need of pneumatic valve rod 7 detect is connected, and the other end is connected with a tank.
Pneumatic means 1 comprises pneumatic body 11, moving structure, moving structure comprises seal pad 14, air-leg 13, pneumatic 12, one end of air-leg 13 is connected with seal pad 14, the other end of air-leg 13 is connected with pneumatic 12, pneumatic body 11 hollows, seal pad 14 is positioned at pneumatic body, seal pad 14 forms a sealing area with the bottom of pneumatic body 11, the bottom of pneumatic body 11 is connected with a draft tube 2, after draft tube 2 air inlets, air pressure can promote seal pad 14 and move upward, and seal pad 14 drives pneumatic 12 on air-leg 13 and air-leg 13 to move upward.
Four altogether of pneumatic means 1, the size of each pneumatic means 1 is all not identical, for adapting to the pneumatic valve rod 7 of different sizes, pneumatic 12 of each pneumatic means 1 is all replaceable, four pneumatic means 1 are arranged on a substrate 6, the draft tube 2 of each pneumatic means 1 is connected with a baroswitch 8 separately, for controlling air pressure, enters in pneumatic body 11.Baroswitch 8 is positioned on substrate 6.Draft tube 2 is positioned at the below of substrate 6, below be connected to the bottom of pneumatic body 11, for giving pneumatic body 11 air feed.
Pneumatic 12 is to be changed a social system and formed by the assembling fittings of pneumatic valve, and pneumatic means 1 has four kinds of different models, can change according to the size of the pneumatic valve rod that will detect for pneumatic 12, for adapting to the detection of the pneumatic valve rod of all models of prior art.
At pneumatic body 11 coboundarys, be provided with a circle clip 3, clip 3 is provided with plum blossom setting nut 31, and for regulating the degree of tightness of clip 3, clip 3 needs the pneumatic valve rod detecting on pneumatic body 11 for fixed placement.
While carrying out the sealing propertytest of pneumatic valve rod, first according to the size of pneumatic valve rod 7, select corresponding pneumatic means, regulate clip 3, pneumatic valve rod 7 is placed on pneumatic body 11, locking hoop 3, make pneumatic valve rod 7 be fixed on pneumatic with it.Water inlet interface 4 is threaded with needing the position of detecting on pneumatic valve rod 7.Open subsequently the corresponding baroswitch 8 of selected pneumatic means 1, carry out air feed, motion and the piston movement of moving structure in pneumatic body 11 is similar.Air pressure can promote seal pad 14 and move upward, thereby promote pneumatic 12, moves upward, and pneumatic 12 through hole 71 positions that move to pneumatic valve rod 7, for blocking the through hole 71 of pneumatic valve rod 7.Then the interface 4 of intaking is intake, and observation pneumatic valve rod 7 needs the position of testing whether to have overflow, with this, tests impermeability, if pneumatic valve rod 7 needs the position of testing to have overflow, represents that this test position exists gas leakage possibility.If air pressure gas leakage simultaneously, the value on rain glass 5 can decline, and this is also an index of the pneumatic property of monitoring pneumatic valve rod.
As mentioned above, sanitary pneumatic valve stem seal device for fast detecting of the present utility model, the detection mode that has adopted gas to combine with liquid, can detect impermeability more intuitively; And device for fast detecting assembly of the present utility model is still less, test more conveniently sooner, promoted production efficiency and production capacity; In addition, this device is simple to operate, and the pneumatic valve rod that need are detected is placed on pick-up unit, and whether after the water flowing of then ventilating, position is detected by observation post overflow, and testing result is accurately accurate, and cost is low, and safe and practical property is high.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
