Description
Technical field
The utility model relates to a kind of airtight detection gas tank, more specifically, relates to the gas tank used in the equipment that such as products air tightness such as microphone sound film or loudspeaker sound film detects.
Background technology
Existing air tightness detection equipment generally includes high pressure filter, the pressure regulator valve be connected with high pressure filter gas circuit, the gas filling valve that is connected with pressure regulator valve gas circuit, the gas tank be connected with gas filling valve gas circuit, gas tank is connected with tested product gas circuit by an opening, and gas tank is also connected with vent valve gas circuit; Pneumatic supply is inflated to gas tank through filter, pressure regulator valve and gas filling valve, and baroceptor is for measuring the air pressure of gas tank inside; Gas tank is vented by vent valve.
For detecting the microphone air tightness detection equipment of these series products such as sound film or loudspeaker sound film, the gas tank of use is usually less and have requirement to gas tank internal volume; And require Measurement accuracy gas tank air pressure inside.This makes when designing gas tank and sensor installs, and gas tank is often designed to two lid formulas, and sensor is arranged on gas tank inside.
But, together with this two lid formula gas tanks need to be screwed in by two lids by encapsulant and screw, there is the risk of leaking gas between Liang Gai, and to process materials require high, cost is also high.And existing mode sensor being arranged on two lid formula gas tank inside, when maintenance maintenance, need gas tank to take apart, workload is large, technical difficulty is high.
In addition, if when baroceptor being arranged on gas tank outside and being connected with gas tank by gas circuit, baroceptor and gas tank inside can be made to have thin channel owing to adding gas circuit, cause the stabilization time of air pressure inside long.
Utility model content
For the problems referred to above that prior art exists, the utility model provides a kind of good seal performance and the simple airtight detection gas tank of technique.
A kind of airtight detecting apparatus gas tank that the utility model provides, comprising:
The hollow housing of one end open, the inwall side face of described opening is provided with the first threaded area, and described hollow housing is provided with inflation inlet and exhausr port, and connects the air-path interface of tested product;
There is the sealing adaptor of groove, the outer peripheral face at least partially of described sealing adaptor is provided with the second threaded area, described sealing adaptor is arranged in described opening and described second threaded area and engages with described first threaded area, in the groove of described sealing adaptor, embedding has epoxide resin material, and is furnished with mutually insulated in described epoxide resin material and extends to the wire of described hollow housing inside through described groove;
Be provided with the printing board PCB of baroceptor, it is inner that described PCB is arranged on described hollow housing, and be welded on described wire.
Alternatively, described air-path interface is arranged on the other end relative with described opening of described hollow housing.
Alternatively, described inflation inlet and described exhausr port are same interface on described hollow housing.
Alternatively, described gas tank is applied in the airtight detecting apparatus of microphone sound film or loudspeaker sound film air-leakage test.Preferably, described gas tank is the parts in direct press type airtight detecting apparatus.
In gas tank of the present utility model, due to the inner peripheral surface of the outer peripheral face of sealing adaptor and one end of hollow housing being respectively arranged with threaded area, the mode that sealing adaptor can directly be screwed is installed on gas tank, and technique is simple, good airproof performance.Because the sealing adaptor with baroceptor of the present utility model can be select commercially available sealing adaptor standard component to carry out respective handling to obtain, therefore cost can be greatly reduced while raising sealing property.In addition, when carrying out maintenance maintenance to gas tank and sensor, also only sealing adaptor need be outwarded winding from gas tank, simple to operation.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the airtight detecting apparatus gas tank according to the utility model one embodiment.
Wherein, the label in accompanying drawing 1 is as follows:
Hollow housing 10, interface 12, air-filled pore 14, exhausr port 16;
Threaded area 24, epoxide resin material 26, sealing adaptor 28;
Pcb board 30, baroceptor 32, wire 34.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
Fig. 1 shows the structural representation according to airtight detecting apparatus gas tank of the present utility model.As shown in Figure 1, this gas tank is integral type gas tank, comprises hollow housing 10, and one end of hollow housing 10 has opening, and relative one end is provided with the interface 12 that gas circuit connects tested product.Hollow housing 10 is also provided with inflation inlet 14 and exhausr port 16.The inner circumferential sidewall of the opening of hollow housing 10 is provided with the first threaded area.
Described gas tank also comprises sealing adaptor 28, the outer peripheral face at least partially of sealing joint 28 is provided with the second threaded area, so that sealing adaptor 28 can be installed to open interior (threaded area gone out as shown in the reference numeral 24) by screwing at least partially, wherein the first threaded area and the second threaded area engagement.As shown in Figure 1, the outer peripheral face of sealing adaptor 28 one end is provided with screw thread.Alternatively, also can be sealing adaptor 28 whole outer peripheral faces on be provided with screw thread.
Sealing adaptor 28 is provided with a groove, can filling epoxy resin material 26 in groove, in order to ensure the sealing of sealing adaptor, can adopt the mode filling epoxy resin material of embedding.During embedding, put into the some wires 34 extending through groove.Wire 34 can be the wire needed for baroceptor 32, and it can be selected simple metal line and avoid contacting with each other or using enameled wire.
Baroceptor 32 is arranged on small-sized or micro-printed circuit board PCB30, and PCB30 can directly be welded on wire 34.If metal or enameled wire for having sufficient intensity that wire is selected, can directly play a supportive role to sensor, without the need to additionally fixing.
In an embodiment of the present utility model, in sealing adaptor 28 after encapsulated epoxy resin material 26, the PCB30 being provided with sensor is welded on the wire 34 be arranged in epoxide resin material 26.Then, be directly screwed on gas tank by the sealing adaptor 28 with baroceptor 32, namely complete installation, structure is simple, easy to operate.And, when carrying out maintenance maintenance, also just just can from gas tank sealing adaptor of outwarding winding.
Implement in novel embodiment at this, sealing adaptor can be adopt commercially available standard pipe sealing adaptor.As long as taken down by the O-ring seal of sealing adaptor inside, just epoxy resin encapsulated can be carried out.Owing to adopting standard component, therefore gas tank gas leakage risk diminishes, reduces technological requirement, and cost also reduces.Carry out embedding with common epoxide resin material also can reduce costs further.
It should be noted that, the position of the interface 12 shown in Fig. 1, inflation inlet 14 and exhausr port 16 is only schematic, and it also can be other positions being arranged on housing 10 that those skilled in the art can understand interface 12, inflation inlet 14 and exhausr port 16.Alternatively, inflation inlet and exhausr port can be identical interfaces, must not arrange separately.
The disclosure should be regarded as the illustration to the utility model principle, is not the utility model to be restricted in the scope of exemplified embodiment.When not departing from spirit of the present utility model, those skilled in the art can expect many distortion, and protection domain of the present utility model should be determined by the content of appended claims.
