Abstract

The invention relates to a plug. The plug comprises a handle and a support, wherein the excircle of the support is provided with a thread. The plug is characterized in that: one end of the handle is fixedly provided with an eccentric wheel; a spindle is arranged in an inner hole of the support; the lower end of the spindle is provided with a step; a sealing sleeve is sleeved between the step of the spindle and the lower end face of the support; the upper end of the spindle stretches out of the support; and the eccentric wheel is hinged to the upper end of the spindle and contacted with a support groove at the upper end of the support. During use, the plug is arranged in an orifice of a gas storage barrel through the external thread of the support, the eccentric wheel is rotated by the handle, the spindle moves upwards, the sealing sleeve is stressed and expanded to plug the inner end face of the gas storage barrel, and a plug hole is more tightly attached when gas pressure in the gas storage barrel is higher, so that the plugging sealing property is enhanced, the gas tightness and safety of the gas storage barrel during detection are ensured, and the working time of an inspector is shortened. The plug has a simple structure and is convenient to operate.

Description

A kind of plug

Technical field

The present invention relates to a kind of plug, especially a kind of plug that detects the gas cylinder sealing.

Background technique

The plug of existing detection gas cylinder sealing comprises handle and bearing.Make the nut on plug and the gas cylinder flexibly connect also fastening through handle; Plug makes the stressed expansion of the rubber pad on the nut seal the exterior edge face of nut, in the airtight checkout procedure of gas cylinder, if the precision of plug is low excessively; When the gas cylinder internal pressure increases; Cause the sealing of rubber pad to descend, make detection person can't correctly judge the reason of gas cylinder leakage gas, prolonged detection person's operating time; While possibly caused plug to become flexible even flown out, so can't guarantee the sealing of gas cylinder and detection person's safety.

Summary of the invention

The invention provides a kind of plug, can solve the gas leak phenomenon in the gas cylinder air tight test process, shorten detection person's operating time.

The technological scheme that the present invention adopts is following: a kind of plug, comprise handle and bearing, and the cylindrical of bearing is provided with screw thread; It is characterized in that: an end of handle is fixed with eccentric wheel, and a mandrel is contained in the endoporus of bearing, and the lower end of mandrel is provided with step; Be with stuffing box gland between the step of mandrel and the lower end surface of bearing; Stretch out from bearing the upper end of mandrel, and eccentric wheel is hinged on the upper end of mandrel, and eccentric wheel contacts with the support slot of bearing upper end.

Beneficial effect: during use, plug is contained in the aperture of gas cylinder through the outside thread of its bearing, rotates eccentric wheel through handle, moves on the mandrel; Make the stressed expansion of stuffing box gland, the interior edge face of shutoff gas cylinder is when the gas cylinder air pressure inside heals big; The place's applying of blocking up is tighter, strengthens the shutoff sealing, has guaranteed tightness and Security when gas cylinder detects; Shortened the inspectoral operating time, this plug is simple in structure, and is easy to operate.

Description of drawings

Fig. 1 is a longitudinal section of the present invention.

Fig. 2 is the schematic representation of the present invention under sealing state.

Embodiment

As shown in Figure 1, a kind of plug comprises handle 1 and bearing 2, and the cylindrical of bearing 2 is provided with screw thread; It is characterized in that: an end of handle 1 is fixed with 3, mandrels 4 of eccentric wheel and is contained in the endoporus of bearing 2, and the lower end of mandrel 4 is provided with step, is with stuffing box gland 5 between the lower end surface of the step of mandrel 4 and bearing 2; Stretch out from bearing 2 upper end of mandrel 4, and eccentric wheel 3 is hinged on the upper end of mandrel 4, and eccentric wheel 3 contacts with the support slot of bearing 2 upper ends, and is as shown in Figure 2; Handle 1 horizontally rotates, and eccentric wheel 3 cooperatively interacts with bearing 2, and bearing 2 and nut are flexibly connected; Handle 1 rotates, and mandrel 4 cooperatively interacts with bearing 2, makes the two ends stressed expansion simultaneously of stuffing box gland 5.
