Abstract
The utility model relates to a high-pressure large flow air valve which comprises an action operating mechanism and a valve body, wherein the action operating mechanism is assembled at one end of the valve body in which a longitudinal through hole is arranged. A valve rod is assembled in the through hole, and a sealing piston is respectively arranged at both ends of the valve rod. An operating rod of the action operating mechanism is driven and assembled at the outer end of the sealing piston of the same side, and a left and a right sets of sealing pairs are arranged on the middle hole wall of the through hole and the corresponding position of the valve rod. An air inlet is communicated on the through hole wall arranged between the piston of one side and the sealing pair of the same side, and an air outlet is communicated on the through hole wall between the left and a right sets sealing pairs. A return spring is installed on the outer end of the sealing piston of the valve rod, which is arranged at the other end of the valve body. The sealing area of a sealing surface of the sealing piston arranged at the air inlet side is larger than the sealing area of the sealing pair of the same side, and thus outward pressure is generated when the high-pressure gas is input. Under the condition of ensuring the flow capacity requirement, the gas pressure becomes the main sealing force and the spring force is the assisting pressure and the reseat pressure.
Description
Technical field
The utility model relates to a kind of air valve, relates in particular to a kind of high-pressure large flow gas valve.
Background technique
At present, the general volume of high-pressure high-flow class electromagnetic gas valve is bigger, and the characteristics of this class electromagnetic gas valve are to rely on the spring force sealing fully, therefore spring is thicker, requires rigidity big, though can satisfy the sealing force requirement like this, but the spring fatigue limit is lower, use the rear spring fatiguability repeatedly, can cause the solenoid valve cisco unity malfunction, influence the solenoid valve life-span.
The model utility content
The purpose of this utility model is to provide a kind of high-pressure large flow gas valve, under the situation that guarantees working pressure and flow, reduces the volume of air valve as far as possible, and improves sealing means, improves the reliability that air valve uses.
For achieving the above object, the technical solution of the utility model is: a kind of high-pressure large flow gas valve, comprise action operating mechanism and valve body, the setting of action operating mechanism is assemblied in an end of valve body, be provided with through hole longitudinally in the valve body, be equipped with valve rod in the through hole, the two ends of valve rod are equipped with packed-piston, the operating handle transmission of action operating mechanism is fitted in the external end head place of homonymy packed-piston, two cover sealings are paid about being equipped with on the valve rod of the middle part of through hole hole wall and corresponding position, be communicated with suction port on the through-hole wall between paying at a side piston with side sealing, about be communicated with the air outlet on the through-hole wall of two cover sealings between paying, on the external end head of the valve stem seal piston of the valve body the other end Returnning spring is installed, the sealing area of the sealing surface of described air inlet side packed-piston is greater than the sealing area of paying with side sealing.
About described two cover sealings pay respectively by the annular seal valve seat should and the corresponding conical surface constitute, left and right sides ring-type seal valve seat is installed on the through-hole wall about respectively relatively, expands the conical surface that receive the outer end in the middle of being with two conical surfaces of left and right sides ring-type seal valve seat corresponding matching.
Be communicated with exhaust port on the through-hole wall between paying at the opposite side piston and with side sealing.
The packed-piston that install at the two ends of valve rod the sealing area of sealing surface equate.
Described action operating mechanism is an electromagnet action operating mechanism.
Because the sealing area of the sealing surface of air inlet side packed-piston of the present utility model is greater than the sealing area of paying with side sealing, thereby when the input pressurized gas, produce outside pressure, under the condition that dependable flow requires, make gas pressure become main sealing force, spring force is aux. pressure and reseat pressure.The spring design just can be curled up by change and recently be reduced spring rate like this, improves the fatigue strength of spring, improves solenoid valve life-span and stable use condition simultaneously.This valve arrangement compactness compares with domestic similar solenoid valve, and volume can reduce 1/3rd.
Description of drawings
Fig. 1 is the structural representation of exemplary embodiments of the present utility model.
Embodiment
As shown in Figure 1, this mode of execution is a kind of high-pressure high-flow solenoid valve, this solenoid valve comprises electromagnet action operating mechanism 1 and valve body 5, electromagnet action operating mechanism 1 is provided with an end that is assemblied in valve body 5, be provided with through hole longitudinally in the valve body 5, be equipped with valve rod 4 in the through hole, the two ends of valve rod 4 are equipped with packed-piston 10, operating handle 2 (this example the is a push rod 2) transmission of electromagnet action operating mechanism 1 equipped (this example is the top dress) is at the external end head place of homonymy packed-piston 10, two cover sealings are paid about being equipped with on the valve rod of the middle part of through hole hole wall and corresponding position, be communicated with suction port 8 on the through-hole wall between paying at a side (in this example in electromagnet action operating mechanism 1 side) piston 10 with side sealing, about be communicated with air outlet 9 on the through-hole wall of two cover sealings between paying, on the external end head of the valve stem seal piston 7 of the valve body the other end Returnning spring 6 is installed, the sealing area of the sealing surface of suction port 8 side sealing pistons 10 is greater than the sealing area of paying with side sealing.About two cover sealings pay respectively by annular seal valve seat 3,7 should and the corresponding conical surface constitute, left and right sides ring-type seal valve seat 3,7 is installed on the through-hole wall about respectively relatively, expands the conical surface that receive the outer end in the middle of being with two conical surfaces of left and right sides ring-type seal valve seat 3,7 corresponding matching.Be communicated with exhaust port 11 on the through-hole wall between paying at opposite side piston 10 and with side sealing.The sealing area of the sealing surface of the packed-piston 10 that install at the two ends of valve rod 4 equates.
During work, electromagnetic gas valve suction port 8 input pressurized gas under not energising situation, press valve seat 3 with air flow partition at the gentle pressure P effect of spring force lower valve rod 4 conical surfaces, and air outlet 9 and relief opening 11 airless pass through.When 1 energising of electromagnet action operating mechanism produces electromagnetic force, promote valve rod 4 by push rod 2 and move right, open sealing surface, air-flow is discharged by air outlet 9 through suction port 8; Simultaneously the valve rod 4 right conical surfaces are pressed on the right side valve seat 7, with the air flow partition of 8 of relief opening 11 and suction ports.When 1 outage of solenoid valve action operating mechanism, electromagnetic force disappears, and valve rod 4 is moved to the left under the promotion of atmospheric pressure P and spring 6 and combines closely with left side valve seat 3, and with air flow partition, air outlet 9 residual gass are discharged by relief opening 11 by sealing surface.
