Description

Cold air pressure testing fixture

A kind of tensimeter of the utility model refers to a kind of interpretation, cold air pressure testing fixture easy to use of being easy to especially.

As shown in Figure 7, be the cold air pressure testing fixture of commonly using, it has two

tensimeters

81,82, portrayal has a circle temperature scale 83 and a circle pressure scale 84 on the surface of each

tensimeter

81,82, operating personnel need with reference to each pointer institute on two

tensimeters

81,82 respectively temperature indicative scale 83 and pressure scale 84 come interpretation when different room temperatures, the refrigerant force value that cold air is interior.The rather cumbersome complexity of process of its interpretation pressure of pressure testing fixture of structure as mentioned above, regular meeting makes operating personnel produce the situation of interpretation mistake.

Because this equal pressure testing fixture needs when interpretation with reference to the numerical value on two tables; so can expend the long period; and when filling the refrigerant detection; the pointer of two tables all is at the state that moves, and is more difficult when making interpretation pressure, and regular meeting causes the pressure after the filling higher; press, in right amount, in time fill refrigerant and be difficult to fit; so fill the refrigerant operating type, not only efficient is poor, and causes the waste of refrigerant easily.

Fundamental purpose of the present utility model is, provide a kind of cold air pressure testing fixture for solving the above problems, owing to except that pressure scale, be provided with a temperature alignment point on this manometric surface, and be pivoted with one on this manometric transparency cover and can rotate the display disc of adjusting by turn-button, portrayal has temperature scale and several pressure blocks of arranging along the display disc periphery on this display disc, can rotate display disc by turn-button, so that the temperature scale of room temperature is corresponding with the temperature alignment point, and borrow the position of the pressure block on gauge hand and the display disc to concern the detected pressures source, to reach the effect that is easy to interpretation.

Of the present utility model time a purpose is that for a kind of cold air pressure testing fixture is provided, it is to combine with tensimeter by the larger area chassis, makes tensimeter can borrow this chassis to be fixed on the box body, can produce preferable fixed effect.

The purpose of this utility model is realized by following technical scheme.

A kind of cold air pressure testing fixture, be in a box body, to be provided with a tensimeter and a thermometer, this tensimeter has a joint to be connected with pressure source, it is characterized in that: also be provided with a temperature alignment point on the described manometric surface, and be pivoted with a display disc on this manometric transparency cover, portrayal has temperature scale and several pressure blocks of arranging along the display disc periphery on this display disc, and this display disc extends the transparency cover end face and is provided with a turn-button, for rotating display disc, so that the temperature scale of room temperature is corresponding with the temperature alignment point by turn-button.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid cold air pressure testing fixture, tensimeter bottom surface lock wherein is provided with a chassis, is fixed in box body to borrow the chassis.

Aforesaid cold air pressure testing fixture, tensimeter wherein has one second joint, and this second joint is to communicate with the joint that is connected pressure source.

The utility model borrows the position of the pressure block on gauge hand and the display disc to concern the detected pressures source, and reaching the effect that is easy to interpretation, and tensimeter can be fixed on the box body by means of this chassis, can produce preferable fixed effect.

For further understanding technology contents of the present utility model, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is an exploded perspective synoptic diagram of the present utility model.

Fig. 3 is III-III line cut-open view of Fig. 1.

Fig. 4 is the manometric user mode synoptic diagram of the utility model.

Fig. 5 is the utility model user mode synoptic diagram one.

Fig. 6 is the utility model user mode synoptic diagram two.

Fig. 7 commonly uses cold air pressure testing fixture.

See also Fig. 1 to Fig. 4, the utlity model has a box body 1, this box body 1 is made up of a loam cake 11 and a lower cover 12, be provided with a tensimeter 2 and a thermometer 3 in this box body 1, this tensimeter 2 bottom surfaces lock is provided with a larger area chassis 13, to borrow chassis 13 to be locked in lower cover 12, this tensimeter 2 has one first joint 21 to be connected with pressure source, and has second joint 22 that communicates with first joint 21, on the surface 23 of this tensimeter 2 except that pressure scale 24 and be provided with a temperature alignment point 25, and be pivoted with a display disc 27 on the transparency cover 26 of this tensimeter 2, portrayal has temperature scale 271 and four pressure block A that arrange along display disc 27 peripheries on this display disc 27, B, C, D, and this display disc 27 extends transparency cover 26 end faces and is provided with a turn-button 28, in order to do rotating display disc 27 by turn-button 28.

When being used to check pressure, the operator checks the temperature on the thermometer 3 earlier, with 30 ℃ of room temperatures is example, the operator needs the temperature alignment point 25 on 30 ℃ temperature scale 271 alignment surfaces 23 on the display disc 27, pipeline with pressure source is connected with first joint 21 again, as shown in Figure 5, can drop on this moment among that pressure block A, B, C, D of display disc 27 by the pointer 29 of tensimeter 2, the force value of coming this pressure source of interpretation how, with pressure block A, B, C, D among Fig. 4 is example explanation, represents that then hypotony need fill if pointer 29 drops on pressure block A place; Pointer 29 drops on the depression belt of pressure block B place expression pressure in permissible range; It is suitable that pointer 29 drops on pressure block C place expression pressure; Pointer 29 drops on pressure block D place and represents that then hypertonia needs pressure release, so, can make the operator easily and exactly interpretation go out the pressure condition of pressure source.

When need are released refrigerant, can borrow first joint 21 to be connected with the pipeline of pressure source, again by second joint, 22 relieving pressures, as shown in Figure 6, so also can be in the time of pressure release its force value of synchronous monitoring, when reaching suitable pressure, stop the action of pressure release in real time, can simplify the program of filling or checking pressure during pressure release with the refrigerant pressure in cold air.

In sum, the utility model can have following effect by said structure:

One, can rotate display disc 27 by turn-button 28, aim at temperature alignment point 25, and close the detected pressures source, can reach the effect that is easy to interpretation by means of the position of the pressure block A on tensimeter 2 pointers 29 and the display disc 27, B, C, D with the temperature scale 271 of room temperature.

Two, this tensimeter 2 has first and

second joint

21,22 that communicates, and can be connected with the pipeline of pressure source, with the force value of this pressure source of synchronous monitoring when the pressure release, to obtain suitable pressure and to avoid unnecessary waste.
