Description
Technical field: the present invention relates to a kind of S. A. loading and unloading valve inside aerating and exhaust device, it can fill fast, exit, and loading and unloading automobile, motor cycle tire valve inside are conveniently.
Background technology: how to guarantee that automobile is in the middle safe operation of running at high speed, be important problems of field army, in the problems referred to above air pressure of automobile tire balanced consistent be one of essential condition, balanced consistent in order to ensure air pressure of automobile tire, just need detect to inflation of tire, venting and to its charge air.Inflation of tire, venting are all finished by valve inside, are by valve inside external pressure to be pressed in the tire inner tube as inflation, and venting is then by screwing out the suitable gas of putting in the tire inner tube of valve inside.Chinese patent discloses " a kind of tire pressurize charge gun ", and its number of patent application is 97205088.4, and the function of a kind of automatic inflation and installation valve inside is provided in this technology.But structure is too complicated.And be not suitable for finishing fast under night or severe environmental conditions the tyre repair task, it can't use easily and fast in field operations vehicle maintenance and repair unit.
Summary of the invention: the purpose of this invention is to provide a kind of S. A. loading and unloading valve inside aerating and exhaust device, it can finish the tyre repair task easily and fast under night or severe environmental conditions, simple in structure easy to use.
The object of the present invention is achieved like this, design a kind of S. A. loading and unloading valve inside aerating and exhaust device, it is characterized in that: it is by joint 1, steady arm 2, handle 5, three-way pipe 4, communicating pipe 6, loading and unloading valve mandrel 10, three cowlings 11 connect and compose, loading and unloading valve mandrel 10 is to bend at the front end of staight shank axle crank shaft is arranged, the crank shaft top of loading and unloading valve mandrel 10 is connected with handle 5, be with three-way pipe 4 successively on the loading and unloading valve mandrel 10 staight shank axles, communicating pipe 6, steady arm 2, joint 1, be with three cowlings 11 of fixation at three-way pipe 4 two ends near the crank position, gas-charging connection 3 is arranged at three-way pipe 4 bottoms.
Described three-way pipe 4 is being connected with " O " RunddichtringO 8 near the crank portion bit port, and there is snap ring 7 another port, and snap ring 7 is stuck in and is enclosed within the three-way pipe 4 therewith in the draw-in groove 9 of the cooresponding loading and unloading valve in position mandrel 10; This port is connected with the port sealing of communicating pipe 6, and the another port of communicating pipe 6 and steady arm 2 one ends are tightly connected, and the other end of steady arm 2 and joint 1 are tightly connected.
Be with " O " type circle 8 in the described steady arm 2.
The gas-charging connection 3 of described three-way pipe 4 bottoms is interconnected with the two-port of three-way pipe 4.
Characteristics of the present invention are: the present invention can not only finish tire inner tube in not enough supplemental inflation of air pressure and the too high venting of air pressure, and can finish tire inner tube and not have inflation under the gas situation.It is simple in structure, cost is low, can finish the tyre repair task easily and fast under night or severe environmental conditions.
The present invention will be further described below in conjunction with the embodiment accompanying drawing:
Description of drawings: Fig. 1 is an embodiment of the invention structural representation:
Fig. 2 is loading and unloading valve mandrel and handle, three-way pipe connection diagram.
Among the figure: 1, joint; 2, steady arm; 3, gas-charging connection; 5, handle; 4, three-way pipe; 6, communicating pipe; 7, snap ring; 8, " O " type circle; 9, draw-in groove; 10, loading and unloading valve mandrel, 11, three cowlings.
The specific embodiment: embodiment as shown in Figure 1, it is connected and composed by joint 1, steady arm 2, handle 5, three-way pipe 4, communicating pipe 6, loading and unloading valve mandrel 10, three cowlings 11, loading and unloading valve mandrel 10 is to bend at the front end of staight shank axle crank shaft is arranged, the crank shaft top of loading and unloading valve mandrel 10 is connected with handle 5, be with three-way pipe 4, communicating pipe 6, steady arm 2, joint 1 successively on the loading and unloading valve mandrel 10 staight shank axles, be with three cowlings 11 of fixation at three-way pipe 4 two ends near the crank position, three-way pipe 4 bottom vertical are communicated with gas-charging connection 3.Be with " O " type circle (8) in the steady arm 2.
As shown in Figure 2: three-way pipe 4 is being connected with " O " RunddichtringO 8 near the crank portion bit port, and there is snap ring 7 another port, and snap ring 7 is stuck in and is enclosed within the three-way pipe 4 therewith in the draw-in groove 9 of the cooresponding loading and unloading valve in position mandrel 10; This port is connected with the port sealing of communicating pipe 6, communicating pipes 6 the right and three-way pipe 4 left ends be tightly connected, communicating pipes 6 left side and steady arm 2 right-hand members be tightly connected, the left end of steady arm 2 and joint 1 are tightly connected.
During use, when the venting of S. A. loading and unloading valve inside aerating and exhaust device, turning handle 5 drives the valve inside rotation and outwards screws out and be positioned in the steady arm 2, when air pressure is charged to tire governing criterion atmospheric pressure value, turning handle 5 drives valve inside, thereby be tightened in the tyre valve core mouth, finish bleeding a tire.When S. A. loading and unloading valve inside aerating and exhaust device supplemental inflation, because tire inner tube has gas, upwards push valve inside, turning handle 5 drives the valve inside rotation and outwards screws out and be positioned in the steady arm 2, when air pressure is charged to tire governing criterion atmospheric pressure value, turning handle 5 drives valve inside, thereby is tightened in the tyre valve core mouth, finishes the tire supplemental inflation.When the inflation of S. A. loading and unloading valve inside aerating and exhaust device (tire inner tube does not have gas), at first valve inside is back-outed, be placed in the steady arm 2, put on the air, when air pressure is charged to tire governing criterion atmospheric pressure value, turning handle 5 drives valve inside, thereby is tightened in the tyre valve core mouth, finishes inflation of tire.
