Abstract
The utility model relates to a direct-action combined valve, which is composed of a valve body, a valve core, an iron core, an electromagnetic assembly, a spring and a guiding mouth, an air inlet is arranged on the lower side of the valve body, the electromagnetic assembly is arranged on the middle of the valve body, the valve core and the iron core are arranged in the electromagnetic assembly, and the spring is arranged between the valve core and the valve body; the iron core is provided with a through hole for flowing the air inside, an outlet of an air intake channel into the valve body is provided with the guiding mouth, so as to radically resolve a defect of degressive sealing property of the old type products. The direct-action combined valve has advantages of professional design, simple structure, safety and reliability.
Description
Technical field: the utility model relates to a kind of direct-acting type combination brake switch and proporting, is mainly concerned with the automobile ABS brake system field of using in heavy truck, the load-carrying tractor.
Background technique: air pressure ABS modulating valve is the main actuator in the anti-locking system for car, is when emergency brake of vehicle, need play regulating brake chamber pressure size product, and therefore, the quality problems and the reliability of product are extremely important.At present, heavily card, the widely used relay valve of trailer are piston type on the market, be to promote piston by increasing air pressure, open valve, the defective of this product specification is to rely on air pressure to promote piston, and the interior external sealed of piston is by O shape circle, and automobile constantly brakes, and can cause the sealability of piston to descend, thereby has influence on the safe handling of brake.
Summary of the invention; The purpose of this utility model will provide a kind of novel direct-acting type combination brake switch and proporting exactly, and it can fundamentally solve the existing defective of Vintage Product.The purpose of this utility model is to realize like this, the direct-acting type combination brake switch and proporting, formed by valve body, spool, iron core, electromagnetic assembly, spring, pilot port, it is characterized in that: the lower end at valve body is provided with suction port, middle part at valve body is provided with electromagnetic assembly, in described electromagnetic assembly, be provided with spool and iron core, between spool and valve body, be provided with spring; Be provided with the through hole of gas flow in the inside of iron core, the outlet in gas-entered passageway enters into valve body is provided with pilot port.The utility model, reasonable in design, utilize the motion of electromagnetic assembly control spool, thereby overcome the existing defective of Vintage Product.
Description of drawings: Fig. 1 is the utility model structural representation
1, through hole 2, iron core 3, electromagnetic assembly 4, spring 5, guide's slogan 6, valve body 7, spool
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, the utility model direct-acting type combination brake switch and proporting, formed by valve body, spool, iron core, electromagnetic assembly, spring, pilot port, it is characterized in that: the lower end at valve body is provided with suction port, middle part at valve body is provided with electromagnetic assembly, in described electromagnetic assembly, be provided with spool and iron core, between spool and valve body, be provided with spring; Be provided with the through hole of gas flow in the inside of iron core, the outlet in gas-entered passageway enters into valve body is provided with pilot port.During concrete enforcement, when energising, electromagnetic assembly produces magnetic field, and spool is under the effect in magnetic field, overcome the active force of spring, move upward, opened pilot port, thereby opened suction port, spool is connected with iron core this moment, has stopped up the passage of air outlet, and the beginning air feed is given actuator.When dead electricity, during the electromagnetic assembly dead electricity, spool is closed pilot port under the effect of spring, and at this moment suction port is closed, and discharges in the through hole of pressurized air from iron core in execution loop.
