Description

Novel cylinder valve mouth

Technical Field

The utility model belongs to the technical field of the industry gas fills dress, concretely relates to gas cylinder valve.

Background

The method is characterized in that the method is opened for 40 years, the rapid development of national economy of China, the high-speed development of industry drives the unprecedented demand of industrial gas products, the supply of the products is short, under the condition, the industrial gas products such as bamboo shoots emerge in Guangdong bead triangle gas plants after raining, but the method is limited to the current technical means and hardware facilities, the gas filling adopts a hard-to-hard filling mode at the time, namely, a metal inflating nozzle is adopted and is fastened with a gas cylinder valve through threads, the butt joint of the gas cylinder valve and the inflating nozzle is a conical surface-to-arc surface, as shown in figure 1, the filling mode is the filling mode in use in the field, however, the hard-to-hard butt joint mode increases the gas leakage condition once the butt joint is slightly deviated, the gas leakage condition occurs, a filling worker only can adopt the butt joint force of the gas cylinder valve and the inflating nozzle, the force for screwing the threads is increased, and when the sealing effect is difficult to, the fastening mode of knocking by a switch wrench at home is adopted, although a certain effect is achieved when the tool is used, the butt joint mode can be imagined to easily cause thread damage, the butt joint conical surface is scored, the air leakage condition is more serious when the tool is filled next time, so that workers can adopt the fastening mode of knocking by a wrench and a hammer under the common condition, namely the current most common filling situation, the phenomenon that the wrench is often damaged by the mode, a pit appears on the conical filling surface of a valve, the thread deforms, the aperture of a copper top nozzle of the tool is compressed to become small is caused, and the traditional filling mode has defects in the process of long-term operation proved by practice. Even if the filling of the product is certified, the poor tapered filling surface and the damaged screw thread of the cylinder valve cannot be covered, and the user must discharge gas through the screw thread and the filling surface when using the bottle valve, so that the user has poor product experience.

The applicant has applied for utility model patent in 2010, application number CN201020634969.1, industry gas soft seal fills the dress and connects, this utility model is chewed to aerifing and has improved, nevertheless because the condition that the present bottle valve basically exists the dress conical surface and damages, even used industry gas soft seal to fill the dress mode that the dress connects and has avoided the barbarous strike, nevertheless do not do benefit to industry gas soft seal and fill the life that the dress connects yet, so necessary provide a better bottle valve that can use with it in a supporting way, fundamentally solves the drawback that barbary dress brought.

SUMMERY OF THE UTILITY MODEL

The utility model discloses fundamentally has changed original seal structure, adopts new sealing material, has changed the dress mode of filling, has solved all problems that have the defect of gas filling dress in-process.

The novel cylinder valve nozzle comprises an inflation connector, wherein a connecting thread is arranged on the inflation connector, a plane sealing seat used for butt joint is arranged in the inflation connector, and the end face of the plane sealing seat is a plane.

The utility model discloses when using, earlier fill the filling of dress joint with soft seal and to aim at the terminal surface of plane seal receptacle, adopt the screw thread will fill the dress joint and be connected with plane seal receptacle fastening again, the terminal surface of plane seal receptacle is the plane, fills to be equipped with the soft sealing circle on the dress connects, and the soft sealing circle reaches fine gas tightness with plane seal receptacle plane to planar butt joint, fastens after good.

The beneficial effects of the utility model reside in that: the gas filling device has the advantages that violent filling is avoided, the gas filling valve is not damaged, accordingly, the gas filling cylinder valve is prevented from being ill and on duty, leakage during gas filling and discharging is avoided, and the gas filling process is more efficient, convenient and safe and civilized.

Drawings

FIG. 1 is a sectional view showing the butt joint structure between the conical surface of a bottle valve and an inflating nozzle in the prior art.

Fig. 2 is a cross-sectional view of the cylinder valve of the present invention.

Fig. 3 is a sectional view of the cylinder valve of the present invention in use.

Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings.

As shown in fig. 2, a connecting thread 3 is arranged on an inflation connector 2 of a valve body 1, a plane sealing seat 4 is arranged in the inflation connector, and the end face of the plane sealing seat 4 is set to be a plane, as shown in fig. 3, when the valve nozzle is used, the connecting thread 3 is connected with a sleeve 11, and inflation can be started after a sealing soft material 12 at the front end of an inflation tube 13 is butted with the plane sealing seat 4.

It should be noted that, the inflating nozzle used in cooperation with the cylinder valve in this embodiment is an industrial gas soft seal filling joint in patent No. CN2010206349691, and through a filling test on 100 filling cylinder valves, zero damage to the filling cylinder valve can be realized in 2500 times of filling of the cylinder valve.

The beneficial effects of the utility model reside in that: the gas filling device has the advantages that violent filling is avoided, the gas filling valve is not damaged, accordingly, the gas filling cylinder valve is prevented from being ill and on duty, leakage during gas filling and discharging is avoided, and the gas filling process is more efficient, convenient and safe and civilized.

Claims (1)

1. Novel cylinder valve is chewed, including inflatable joint, inflatable joint on be provided with connecting thread, its characterized in that: the inflation connector is internally provided with a plane sealing seat for butt joint, and the end face of the plane sealing seat is a plane.
