Abstract
The utility model relates to an artificial controlled two-position three-way valve, belonging to a pneumatic element, comprising a valve body (2), an air nozzle (5) and an air inlet (12). The utility model is characterized in that the valve body is provided with four small holes (3), the right middle part of a piston rod (1) has a thin diameter, the right end of the piston rod (1) is fixed with a sealing gasket (8) and a spring (10). When the piston rod is moved to right side by a person, the small holes are sealed by seal rings (4), air enter a pipeline, and when the piston rod resets, air pressure in the pipeline is relieved via the small holes. The utility model has the advantages of simple structure, low requirement on the machining precision of parts, and thus production cost is reduced.
Description
The utility model belongs to pneumatic element.
The structure that present domestic stranger is controlled valve is complicated, guiding valve precision height, and the manufacturing difficulty is big, the cost height.
The purpose of this utility model provides a kind of simple in structure, practical, easily manufacturing, and the people who reduces cost is greatly controlled the Pneumatic two-position three-way valve.
The purpose of the utility model can adopt following structure to realize, this valve has valve body (2), the top of valve body has pore and is screwed into valve (5), seal by cushion rubber (6), the valve body right-hand member is screwed into air inlet nozzle (12), seal by cushion rubber (11), there are four apertures (3) in the pore left side that it is characterized in that valve body, piston rod (1) is equipped with at the valve body middle part, the right-hand member of piston rod is sealing gasket (8), fixed by packing ring (9), screw (7), between the spring seat of screw (7) and air inlet nozzle (12) spring (10) is housed, valve body (2) right side endoporus right-hand member is equipped with seal ring (4)
The right middle diameter of piston rod (1) is less than external diameter, and its left is an arc transition, and left end can be semicircle.
Description of drawings is as follows:
Figure is the structural representation of manual control two position three-way valve.
1-piston rod, 2-valve body, 3-aperture, 4-seal ring, 5-valve, 6-seal ring, 7-screw, 8-sealing gasket, 9-packing ring, 10-spring, 11-seal ring, 12-air inlet nozzle
The utility model will be further described in conjunction with the accompanying drawings, manual control piston rod (1) moves right, when the circular arc of piston rod enters seal ring (4), four apertures (3) are sealed, at this moment, sealing gasket (8) leaves valve body (2), and then the source of the gas that is entered by air inlet nozzle (12) divides inflow valve (5) to using air pipe through the small diameter part of piston rod (1).After out of hand, piston rod (1) resets under the effect of spring force, and at this moment, air inlet nozzle comes the sealed pad of source of the gas (8) sealing, and communicates and release with four apertures (3) through valve (5) with the air pressure in the air pipe.
The utility model is controlled valve with existing people and is compared, have simple in structure, part Requirement on machining accuracy is low, thereby greatly reduces production cost.
Claims (2)
1, the manual control two position three-way valve of one of pneumatic element, have pore and be screwed into valve (5) above having valve body (2), valve body, be screwed into air inlet nozzle (12) by cushion rubber (6) sealing, valve body right-hand member, seal by cushion rubber (11), there are four apertures (3) in the pore left side that it is characterized in that valve body, piston rod (1) is equipped with at the valve body middle part, the right-hand member of piston rod is sealing gasket (8), fix by packing ring (9), screw (7), between the spring seat of screw (7) and air inlet nozzle (12) spring (10) is housed, valve body (2) right side endoporus right-hand member is equipped with seal ring (4).
2, manual control two position three-way valve according to claim 1, the right middle diameter that it is characterized in that piston rod (1) are less than external diameter, and its left is an arc transition.
