Description

A quick connection device for a pressure transmitter

technical field

The utility model relates to a quick connection device for a pressure transmitter, which belongs to the mechanical field.

Background technique

In the process of verifying and calibrating the intelligent pressure transmitter, it is found that the various joint sets used now need to remove the original connecting pipes and joints in the process of connecting the pressure transmitter and the pressure source, which is very uncomfortable. convenient. In the calibration process, in fact, it is only necessary to effectively ensure the sealing of the connection between the pressure transmitter and the pressure source so that there is no leakage in the pressure transmission. Therefore, be badly in need of designing a kind of novel special-purpose fast connection device, meet actual needs.

Contents of the invention

In order to overcome the above disadvantages, the utility model provides a quick connection device for a pressure transmitter, which can conveniently and quickly check the intelligent pressure transmitter, and facilitates the connection between the intelligent pressure transmitter and the pressure source.

The technical solution adopted by the utility model is: a quick connection device for a pressure transmitter, which is characterized in that it includes a quick joint and a screw rod, the quick joint is open at both ends, the quick joint and the screw are screwed together, and the other end of the quick joint is connected to the The pressure source is connected; there is a hexagonal nut on the screw rod, the screw rod is hollow inside, and the other end of the screw rod is a conical air source port, which is connected to the drain port of the pressure transmitter.

Further, the screw is welded with the hex nut, and the quick connector is welded with the screw.

Furthermore, the quick connector has a length of 35 mm, an inner diameter of the quick connector of 2.5 mm, and a thickness of 3 mm, and the length of the screw is 25 mm, an inner diameter of the screw of 5 mm, and a thickness of 5 mm.

The implementation of the utility model must firstly play the basic role of sealing the pressure source and the pressure chamber of the intelligent pressure transmitter; secondly, there must be a hexagonal nut in the design, and the connecting nut must be connected to the sewage outlet of the intelligent pressure transmitter. Matching; material selection should be based on actual needs, such as compressive strength, softness and hardness, etc., there are several options with different materials.

The quick connection device of the pressure transmitter provided by the utility model, in actual use, directly enters from the sewage outlet of the intelligent pressure transmitter. On the premise of ensuring air tightness, the calibration speed is greatly accelerated and the work Efficiency has great promotion significance for on-site verification.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Description of drawings

Fig. 1 is a structural schematic view (sectional view) of the present utility model.

In the figure, 1 is a quick connector, 2 is a screw rod, 3 is a thread, 4 is a hex nut, and 5 is a tapered air source port.

Detailed ways

Example:

As shown in Figure 1, a quick connection device for a pressure transmitter is characterized in that it includes a quick joint 1 and a screw 2, the quick joint 1 is open at both ends, the quick joint 1 and the screw 2 are tightened through the thread 3, the quick joint 1 The other end is connected to the pressure source; the screw 2 is provided with a hex nut 4, the screw 2 is hollow inside, the other end of the screw 2 is a conical air source port 5, and the conical air source port 5 is connected to the drain port of the pressure transmitter ; In order to ensure good air tightness, the screw 2 is welded with the hex nut 4, and the quick joint 1 is welded with the screw 2.

In this embodiment, the quick connector is 35 mm long, the inner diameter of the quick connector is 2.5 mm, and the thickness is 3 mm. The length of the screw is 25 mm, the inner diameter of the screw is 5 mm, and the thickness is 5 mm.

When in use, one end of the conical air source port can be screwed into the drain port of the intelligent pressure transmitter through the thread on the screw rod, and the other end can be connected to the pressure source through the joint group or the pressure guiding hose. Under the premise of ensuring airtightness, the pressure of the air source is introduced into the platform and the intervention port; the visual pressure value can be randomly controlled and applied flexibly.
