Abstract
The invention discloses a kind of automobile tyre locking-valve, relate to a kind of vehicle charging and discharging valve, relate in particular to a kind of automobile tyre locking-valve of cross-country vehicle tire central air-charging and air-discharging system.The present invention includes valve body (1), first O-ring seals (2), Screw-thread sealing plug (3), second O-ring seals (4), first straight pin (5), screw (6), handle (7), valve rod (8), valve ball seal ring (9), valve ball (10), second straight pin (11), valve inside (12), valve cock lid (13).The present invention is in light weight, can reduce centrifugal force, and cost is low; Adopt ball-valve structure, easy to operate, good seal performance; On valve body also design have one can for outside charge and discharge the valve cock of gas, can adopt external source of the gas to give tyre inflation when guaranteeing the central air-charging and air-discharging system fault.
Description
Technical field
The present invention relates to a kind of vehicle charging and discharging valve, relate in particular to a kind of automobile tyre locking-valve of cross-country vehicle tire central air-charging and air-discharging system.
Background technique
Locking valve very early by national expenditures such as the U.S., Russia in charging and discharging on the gas automobile tire.Its effect is to block air-flow between tire and rotary seal air chamber by closing locking valve when automobile running, thereby gives the tire pressurize and reduce the wearing and tearing of rotating seal ring; When parking of automobile, tire is communicated with the rotary seal air chamber, thereby gives tyre inflation, venting and pressure measurement by opening locking valve.
Because of the pressure maintaining performance of locking valve, determined locking valve when turn-offing, must have good sealability.If locking valve gas leakage, tire pressure will descend immediately, and this is breakneck when vehicle driving.Offroad vehicle travels in the rugged environment of being everlasting, and locking valve is contained on the wheel hub, outside it is exposed to fully.This just needs locking valve to have well corrosion-resistant, high-low temperature resistant characteristic.Though external locking valve has solved above these problems, the cost of the external Component of import is higher, and the cycle is long.
Summary of the invention
Purpose of the present invention just is to overcome the above-mentioned shortcoming and defect that prior art exists, and a kind of automobile tyre locking-valve of cross-country vehicle tire central air-charging and air-discharging system is provided.
The object of the present invention is achieved like this:
Develop a kind of sealing configuration, guarantee the sealing of locking valve; Selecting copper material for use is valve body material, improves corrosion-resistant, the high-low temperature resistant characteristic of locking valve.
As Fig. 1,2, automobile tyre locking-valve comprises valve body 1, first O-ring seals 2, Screw-thread sealing plug 3, second O-ring seals 4, first straight pin 5, screw 6, handle 7, valve rod 8, valve ball seal ring 9, valve ball 10, second straight pin 11, valve inside 12, valve cock lid 13.
Working principle of the present invention is:
The present invention only provides a valve assembly, is matching used with special detection control system.
When the through hole of valve ball 10 with A mouth a, when B mouth b is vertical, A mouth a and B mouth b turn-off, then automobile tyre locking-valve is in off working state; When handle 7 dextrorotations are turn 90 degrees, (b is parallel and when being positioned at same center line, A mouth a is communicated with B mouth b, and then automobile tyre locking-valve is in running order for the through hole of valve ball 10 and A mouth a, B mouth.
The present invention has following advantage and good effect:
1, in light weight, can reduce centrifugal force, cost is low;
2, adopt ball-valve structure, easy to operate, good seal performance;
3, on valve body also design have one can for outside charge and discharge the valve cock of gas, can adopt external source of the gas to give tyre inflation when guaranteeing the central air-charging and air-discharging system fault.
