Description

A kind ofly repair taking out that inner tube uses and fill dual purpose valve

Affiliated technical field

The utility model relates to a kind ofly to be repaired taking out that inner tube uses and fills dual purpose valve and tee pipe fitting thereof, is applied in the vehicle tyre gas bleeding and inflates in vehicle tyre.

Background technique

Chinese patent has been announced a kind of being entitled as " a kind of repair the pump-line link that inner tube is used " (notification number is CN 2617949Y), it comprises a two-way switchover control valve door, and an outside thread connecting head is fixed by screw thread respectively in valve body rear side, left side and the front side of this valve; Vertically put a taper type air filter in the cavity of front side outside thread connecting head, this filter one end is against on the valve body front panel, and the other end passes through the stage clip outside it of being wrapped in and is against by screw thread and is fixed on the airtight tube inner side end on the outside thread connecting head of front side; A hose coupling is fixed by screw thread by end face central authorities at airtight tube; Valve inner is a solid sphere, and spheroid top has a groove, and left side deep hole and rear side deep hole are interconnected; Valve body top has an axis hole, and in axis hole, the lower end snaps onto in the groove of spheroid by fixed by nut in a rotating shaft, and the square opening of rotating handles is passed in the upper end.Be respectively applied for solution before and after this valve mechanism conversion compressor inlet is communicated with two problems with gas communication in the vehicle tyre and atmosphere.Its shortcoming is that inflation the time has only and pump-line to be pulled up other pipeline of changing with compressor gas holder phase car from the inner tube air valve just can inflate in tire, thereby takes out, inflates body and bother in changing pipeline.In addition, its complex structure, cost of production is higher.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and take out, inflate taking out that gymnastics does that easy, complex structure, repairing inner tube that cost of production is lower use to fill dual purpose valve and tee pipe fitting thereof.

The purpose of this utility model can reach like this, a kind ofly repairs taking out that inner tube uses and fills dual purpose valve, it is characterized in that it comprises square six valve bodies, and its and arranged on left and right sides face is fixed an outside thread connecting head by screw thread respectively; Lower surface is opened an interior threaded hole, and the size in hole is suitable with the ball valve core; The spool fixed block that one ball valve core is spun in the hole is fixed in the cylindrical cavity of valve body; This fixed block is by the hose coupling that is threaded; Ball valve core top open arc groove, left side deep hole and downside deep hole are interconnected; The valve body upper surface has an axis hole, and in axis hole, the lower end snaps onto by the arc tenon in the arc fluting of ball valve core body by fixed by nut in a rotating shaft, and the upper end is passed the square opening of rotating handles and with nut handle fixed; The rotating shaft of the male connection of valve body and arranged on left and right sides face, the spool fixed block of lower surface and upper surface all extend in the valve body cylindrical cavity, and is inconsistent with the ball valve core every a seal ring.

Above-mentionedly a kind ofly repair taking out that inner tube uses and fill dual purpose valve, its feature is that also the upper surface of valve body connects left and right two limiting stoppers integratedly; Handle end connects a stop member integratedly.

A kind of tee pipe fitting is characterized in that a port is matched with the outside thread connecting head of above-mentioned valve body right flank; One port is matched with the pipeline that connects compressor inlet; One port band, one folding lid is connected with atmosphere, and its ventilation bore is greater than with the matched vent of outside thread connecting head.

The utility model has following advantage compared to existing technology:

1, it is easy to take out, fill conversion, need not to pull up pipeline;

2, structural element easy processing;

3, the flexible pipe that links to each other with workpiece is born simultaneously and is taken out, fills load, has reduced the number of times of cover tube drawing; Avoid charging and discharging the loaded down with trivial details of gas connecting tube during the maintenance inner tube of a tyre the biglyyest, improved maintenance man's working efficiency.

Embodiment

The utility model is further described below in conjunction with accompanying drawing.A kind ofly repair taking out that inner tube uses and fill dual purpose valve, the and arranged on left and right sides face of its square six valve bodies (27) is fixed an outside thread connecting head (29,19) by screw thread respectively; Lower surface is opened an interior threaded hole, and the size in hole is suitable with ball valve core (21); The spool fixed block (23) that one ball valve core (21) is spun in the hole is fixed in the cylindrical cavity of valve body; This fixed block (23) is by the hose coupling (25) that is threaded; Ball valve core (21) top open arc groove, left side deep hole and downside deep hole are interconnected; Valve body (27) upper surface has an axis hole, and in axis hole, the lower end snaps onto by the arc tenon in the arc fluting of ball valve core body (21) by fixed by nut in a rotating shaft (7), and the upper end is passed the square opening of rotating handles (9) and with nut handle (9) fixed; The rotating shaft (7) of the male connection (29,19) of valve body (27) and arranged on left and right sides face, the spool fixed block (23) of lower surface and upper surface all extend in valve body (27) cylindrical cavity, and is inconsistent with ball valve core (21) every a seal ring.Handle (9) end is with a stop member (3), and valve body (27) upper surface is fixed a left limit piece (1) and right limit piece (5) integratedly.

A kind of tee pipe fitting, it has three ports.The one, connect port (11) with compressor inlet, the 2nd, with the port (13) that atmosphere connects, this port (13) is with folding lid (15), and the 3rd, connect port (17) with valve body right flank connecting head.

During use, port (11) is linked to each other with the suction port of pipeline with compressor; The same joint of port (17) (19) connects with flexible pipe.The same joint of the outlet of compressor gas holder (29) is fixedly connected with copper pipe.When repairing the inner tube of a tyre, the same hose coupling of the air valve of the inner tube of a tyre (25) is connected with flexible pipe.

When the handle (9) of upper surface rotates counterclockwise in horizontal plane, be subjected to the restriction of left stop block (1) and bounding means (3), handle (9) stops on the limit orientation.At this moment, the connecting head (29) of the same valve body of left deep hole (27) left surface of ball valve core (21) is connected, be cut off between the same hose coupling of connecting head (19) (25) of right flank simultaneously, thereby folding lid (15) is when being opened, extraneous air enters and enters the gas holder of compressor from port (11) from port (13), enters and goes out to the inner tube of a tyre to inflate from the hose coupling (25) of lower surface from the connecting head (29) of left surface at last.

When the handle (9) of upper surface clockwise rotates in horizontal plane, be subjected to the restriction of right stop block (1) and bounding means (3), handle (9) stops on another limit orientation.At this moment, the connecting head (19) of the same valve body of left deep hole (27) right flank of ball valve core (21) is connected, be cut off between the same hose coupling of connecting head (29) (25) of left surface simultaneously, thereby folding lid (15) is when being closed, air in the inner tube of a tyre is compressed into gas holder by the compressor cylinder, finishes and bleeds.In inflation, pumping process, handle (9) can be rotated in the middle of two limit positions, in time finish to inflate or bleed.
