Description
Technical field
The utility model belongs to Mobility Enhancement Vehicle wheel edge system field, is specifically related to a kind of vertical automatic exhaust valve.
Background technique
Existing vertical automatic exhaust valve generally can be divided into spring, gravity type and rotary-open type by the structure of spool.Spring is formed primarily of valve body, flap, spring and back-up ring, and suction port and relief opening lead to mode in straight-through or angle.Its working principle: gas enters outlet valve from suction port, air pressure constantly increases, and after air pressure reaches flap cracking pressure value, spring is compressed, and flap skew causes occurring gap between valve body and flap, and gas is discharged by relief opening through gap; Gravity type is primarily of formations such as valve body, rocking bar, floating drum or ball floats, and its cardinal principle is that the gravity overcoming floating drum or ball float by air pressure comes ascending, descending floating drum or ball float, thus controls the opening and closing of gas circuit; Rotary-open type is also the opening and closing being controlled gas circuit by the motion of air pressure control rotary-open type flap.The exhaust port of existing spring outlet valve and inlet hole generally lead to structure in straight-through or angle, adopt vertical mounting type, exhaust port side can upward or horizontal positioned, aqueous vapor, dust and other floating impurity are easy to enter valve body from exhaust port and cause valve inner block or be etched, more seriously these materials likely infiltrate in system air flue when system exhaust and even enter internal system, and the normal operation of meeting influential system even can erodible system internals.For this problem, mostly adopt now the mode increasing dust cap to protect outlet valve and system, and while increasing dust cap, too increase the weight and volume of outlet valve; There are many outlet valves to need in use to unscrew dust cap, tighten again after finishing using, inconvenient operation.And gravity type and rotary-open type outlet valve stability are not as spring outlet valve, particularly in or the environment that jolts comparatively large at Oscillation Amplitude.
Model utility content
The purpose of this utility model is to provide a kind of vertical automatic exhaust valve that can be used for Mobility Enhancement Vehicle wheel edge system, can at bad environments (environment such as high temperature, low temperature, steam, sand and dust), road conditions are poor, and (Oscillation Amplitude is larger, jolt obvious) when realize system automatic ventilating function, there is solid reliable, good airproof performance, the advantage such as easy for installation.
The technical solution of the utility model is: a kind of vertical automatic exhaust valve, is characterized in that: form primarily of valve body 1, bonnet 2, O RunddichtringO 3, spring 4, spool 5, filter screen 7 and back-up ring 8; Valve body 1 lower end is connected with system gas pipeline joint by screw thread; Inlet hole 10 ecto-entad of valve body 1 lower end is fixed with back-up ring 8 and filter screen 7 successively; Spool 5 is arranged in the passage in the middle part of valve body 1, and bonnet 2 is fixed in the tapped hole of valve body 1 upper end, and O RunddichtringO 3 is arranged on bonnet 2, contacts with valve body 1; Spring 4 is arranged between bonnet 2 and spool 5, and valve body 1 maintains static, and spool 5 moves along valve body 1 axis; Air outlet hole 9 to be opened on body wall and downward-sloping.
The center line of air outlet hole and valve body central shaft are that miter angle is downward-sloping.
Valve body 1 and system gas pipeline joint place are sealed by seal washer 6.
Beneficial effect: the utility model does not need to install dust cap, have employed the mode of beating downwards exhaust port and realizes sealing and automatic vent, make designs simplification, by increasing filter screen 7, being used for impurity screening, keeping air flue clean; The utility model can at bad environments (environment such as high temperature, low temperature, steam, sand and dust), road conditions are poor, and (Oscillation Amplitude is larger, jolt obvious) when realize system automatic ventilating function, there is solid reliable, good airproof performance, the advantage such as easy for installation.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model;
Fig. 2 is overall structure schematic diagram of the present utility model.
Embodiment
For making the purpose of this utility model, content and advantage clearly, below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, vertical automatic exhaust valve is formed primarily of valve body 1, bonnet 2, O RunddichtringO 3, spring 4, spool 5, seal washer 6, filter screen 7 and back-up ring 8 concrete structure of the present utility model; Valve body 1 lower end offers outside thread, is connected with system gas pipeline joint by screw thread; In the inlet hole 10 of valve body 1 lower end, ecto-entad is fixed with back-up ring 8 and filter screen 7 successively, is used for impurity screening, keeps air flue to clean; Spool 5 is arranged in the passage in the middle part of valve body 1, and bonnet 2 is fixed in the tapped hole of valve body 1 upper end, and O RunddichtringO 3 is arranged on bonnet 2, contacts with valve body 1, keeps valve body 1 inner sealing; Spring 4 is arranged between bonnet 2 and spool 5, and valve body 1 maintains static, and spool 5 can move along axis, for controlling gas circuit opening and closing; Seal washer 6 is arranged on the outside thread tool withdrawal groove position of valve body 1 bottom, ensures the sealing between system and outlet valve; Air outlet hole 9 is opened on body wall, is that miter angle is downward-sloping with valve body central shaft.
Because applicable cases of the present utility model is vertically arranged on above related system, downward-sloping exhaust port can effectively reduce drench with rain, floating dust and other impurity enters valve inner by inlet hole, available protecting valve body and air flue and internal system component; Add filter layer between valve body lower end and back-up ring, both the gas that system air flue is discharged can be filtered, and filtered the impurity particle in gas, floating dust and other impurity also can be stoped to enter system air flue from valve body inner; The utility model is offering exhaust port obliquely and after increasing filter layer, can save dust cap, both can reduce valve body quality, also can reduce valve volume, save the operation of degree of tightness dust cap simultaneously, more convenient.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
