Summary of the invention

Technical problem to be solved in the utility model is the defective that remedies above-mentioned prior art, and a kind of designs simplification, reasonable is provided, and vapour-pressure type ball valve sealing pick-up unit simple to operate.

The utility model is solved by the following technical programs.

This vapour-pressure type ball valve sealing pick-up unit, comprise: by the bed die that embeds for ball valve body be used for cylinder constitutes before and after the inflation of ball valve body crosswise fixed ball valve body level, by frame, rack-mounted pressure regulator valve, inflation rotation upper and lower air cylinders, inflation rotary cylinder and the vertically fixing and opening of valves catanator of ball valve body that can a backstay that be stuck in the ball valve switch constitutes to fixed mechanism.

The characteristics of this vapour-pressure type ball valve sealing pick-up unit are:

Comprise that also one is arranged on the pressed gas conveying mechanism that inflation front and back cylinder end can be docked with ball valve one port sealing.

Technical matters of the present utility model is solved by following further technical scheme.

Described pressed gas conveying mechanism comprises one cylinder body, and cylinder body is provided with the air intake opening that a band detects pressure regulator valve, and cylinder body one end is provided with the cylinder mouth that can dock with ball valve one end valve mouth, and the cylinder mouth is provided with sealing gasket.

Described sealing gasket is made of the colloid sealing frame circle that adapts with tested ball valve end valve mouth, around the colloid sealing frame circle by the cylinder mouth end of screw retention at cylinder body.

Described colloid sealing frame circle is provided with can be to entering the filter screen that tested ball valve gas filters.

The utility model compared with prior art has following remarkable result:

This vapour-pressure type ball valve sealing pick-up unit design science, rational in infrastructure.Ball valve in the ball valve sealing detection is fixing and ball valve is opened manipulation and the ball valve sealing detection only needs to adopt a gas transmission mechanism, not only simplify apparatus structure, reduced the device manufacturing expense, improved the accuracy of sealing detection, and made things convenient for operation, improved detection efficiency.

The concrete structure of the utility model vapour-pressure type ball valve sealing pick-up unit is provided in detail by the following drawings and embodiment.

Description of drawings

Fig. 1 is the structural representation of vapour-pressure type ball valve sealing pick-up unit;

Fig. 2 is the pressed gas conveying mechanism structural representation of vapour-pressure type ball valve sealing pick-up unit shown in Figure 1.

Embodiment

Can be clear that vapour-pressure type ball valve sealing pick-up unit from Fig. 1, comprise: the ball valve body level is to the vertically fixing pressed gas conveying mechanism 3 that reaches opening of valves catanator 2 and can dock with the sealing of ball valve one end of fixed mechanism 1, ball valve body.

Described ball valve body level is made of bed die 11 that embeds for ball valve body and the inflation front and back cylinder 12 that is used for the ball valve body crosswise fixed to fixed mechanism 1.

The vertically fixing and opening of valves catanator 2 of described ball valve body by frame 21, be installed in pressure regulator valve 22, inflation rotation upper and lower air cylinders 23, the inflation rotary cylinder 24 on the frame 21 and be installed in the backstay 25 that inflation rotary cylinder 24 ends can be stuck in the ball valve switch and constitute.

Described pressed gas conveying mechanism 3 by the cylinder body 32 that is provided with draft tube 31, be arranged on the detection pressure regulator valve 33 on the draft tube 31 and be arranged on cylinder body cylinder mouth end 34 and constitute with the colloid sealing frame circle 35 that tested ball valve end valve mouth adapts, be fixed on the cylinder mouth end 34 of cylinder body 32 around the colloid sealing frame circle 35 by screw 36.
