Abstract
The utility model discloses a kind of valve body, its drip irrigation device is: comprise body, and described body is provided with water intake and water outlet, described body is also provided with the positioning hole for matching with pressure-bearing cape.The utility model solves existing valve body when doing air-leakage test, the problem be fixed on pressure-bearing cape that can not be stable.
Description
Technical field
The utility model relates to a kind of valve, and in particular, it relates to a kind of valve body.
Background technique
At present, the product produced in many industries has manyly will carry out air-leakage test, and some products are very high to bubble-tight requirement, does not airtightly reach when requiring, is easy to produce security incident.
Such as, in pipeline connects, need the valve used, valve body is wherein the important composition parts of valve.Because valve body can exist the defect such as trachoma, micropore that naked eyes cannot distinguish in the fabrication process, therefore need to carry out air tightness test to valve body.Wherein, application number be 201010298264.1 Chinese patent disclose a kind of housing airtightness detection apparatus, this equipment comprises pressure-bearing cape, inflator and tank, in use, workpiece is fixed on pressure-bearing cape, then tank rises, until workpiece is immersed in the liquid in tank completely, then opens inflator, if the surface being immersed in the workpiece in tank produces bubble, illustrate that bubbling place exists the defect such as pore or crackle, if not bubbling, illustrate that this workpiece is acceptable product.Pressure-bearing cape is provided with the fixing device that can be fixed valve body, fixing device comprises the first Sealing coordinated with water intake, and the second Sealing to coordinate with water outlet, the second Sealing blocks, and the first Sealing is inflated by the inside of inflator to valve body.Fixing device also includes depression bar, and depression bar carries out pressing to valve body to be fixed.
But the structure due to existing valve body exists some defects, what cause that existing valve body can not be stable is fixed on pressure-bearing cape, and the air-leakage test of valve body so will be caused to there is inaccurate situation.Concrete condition is as follows: existing valve body comprises body, and body is provided with water intake and water outlet, and the setting of water intake and water outlet is generally straight-tube, and it can not well coordinate with the first Sealing and the second Sealing.Secondly, existing valve body only relies on water intake and water outlet to coordinate with the first Sealing in fixing device and the second Sealing, then by the pressing effect of depression bar, valve body pressing is fixed on pressure-bearing cape, owing to valve body there is no special position point, so the location of valve body on pressure-bearing cape is stable not.Moreover the depression bar of existing fixing device carries out pressing to the cambered surface of valve body, cause both connections stable not.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of valve body, and this valve body is provided with the special position point matched with fixing device, and then makes stable being fixed on pressure-bearing cape of this valve body.
For achieving the above object, the utility model provides following technological scheme: a kind of valve body, comprises body, and described body is provided with water intake and water outlet, described body is also provided with the positioning hole for matching with pressure-bearing cape.
Preferably, described positioning hole comprises two and forms trigonometric expression with water intake or water outlet and distributes.
Preferably, described body is provided with the bonding facets matched with depression bar.
Preferably, described bonding facets is provided with to increase and wipes lines.
Preferably, described water intake is that shoulder hole is arranged.
Preferably, described water outlet is that shoulder hole is arranged.
The utility model has following advantage: the utility model valve body is provided with the positioning hole for matching with pressure-bearing cape, so when being fixed on pressure-bearing cape, realize the location of this valve body on pressure-bearing cape by positioning hole, the stability that it is fixing can be improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model valve body and air tightness detection equipment;
Fig. 2 is the partial structurtes schematic diagram of the utility model valve body and air tightness detection equipment;
Fig. 3 is the A portion enlarged diagram of Fig. 2;
Fig. 4 is the structural representation one of the utility model valve body;
Fig. 5 is the structural representation two of the utility model valve body.
In figure: 1, air tightness detection equipment; 11, pressure-bearing cape; 12, depression bar; 13, the first Sealing; 14, the second Sealing; 15, locating column; 2, body; 21, water intake; 22, water outlet; 23, positioning hole; 24, bonding facets.
Embodiment
With reference to shown in accompanying drawing, the utility model valve body is further illustrated.
Embodiment: a kind of valve body, comprises body 2, and body 2 is provided with water intake 21 and water outlet 22, body 2 is also provided with the positioning hole 23 for matching with pressure-bearing cape 11.So when being fixed on pressure-bearing cape by this valve body, realizing the location of this valve body on pressure-bearing cape 11 by positioning hole 23, the stability that it is fixing can be improved.
Wherein, positioning hole 23 comprises two and is symmetrically distributed on body 2, and forms trigonometric expression with water intake 21 or water outlet 22 and distribute, when body 2 is subject to external force, coordinating of positioning hole 23 and pressure-bearing cape 11 can the effect of dispersion forces, and the structure arranged in trigonometric expression like this makes location more stable.
Secondly, body 2 is provided with the bonding facets 24 matched with depression bar 12, and coordinate compared to the cambered surface of original valve body, this bonding facets 24 can increase area of contact, makes pressing more stable.
Further, bonding facets 24 is provided with to increase wipes lines, and so, when depression bar 12 with its pressing, frictional force between the two increases, and makes pressing more stable, not easily slides.
Moreover water intake 21 is arranged in shoulder hole, so, when matching with the first Sealing 13, surface of contact can be made to become double layer construction, the density of both raisings.Water outlet 22 is arranged in shoulder hole, so, when matching with the second Sealing 14, surface of contact can be made to become double layer construction, the density of both raisings.
In the present embodiment, air tightness detection equipment comprises pressure-bearing cape 11, inflator and tank, in use, workpiece is fixed on pressure-bearing cape 11, pressure-bearing cape 11 is provided with the fixing device that can be fixed valve body, and fixing device comprises the first Sealing 13 coordinated with water intake 21, and the second Sealing 14 coordinated with water outlet 22, second Sealing 14 blocks, and the first Sealing 13 is inflated by the inside of inflator to valve body.Fixing device also includes depression bar 12, and depression bar 12 pairs of valve bodies carry out pressing to be fixed.Further, pressure-bearing cape 11 is also provided with locating column 15.
When this valve body is fixed on pressure-bearing cape 11, first water intake 21 is matched with the first Sealing 13, water outlet 22 is coordinated with the second Sealing 14, positioning hole 23 coordinates with locating column 15, due to trigonometric expression Structure composing plane that two positioning holes 23 and water intake 21 are formed, coordinate the pressing of upperpush rod 12 again, what it is such that this valve body can be stable is fixed on pressure-bearing cape 11.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
