This creation is a pneumatic tool valve device and other tools, especially the design of pneumatic valves, With long-term durability. [Previous technology] Pneumatic tools such as pneumatic grab are widely used, no matter the drilling or screwing work requirements, they can be completed with high efficiency. The applicant of this creation has been immersed in pneumatic tools for many years, and has applied for a patent for the valve design of pneumatic tools. The new patent case [hereinafter referred to as the "reference case" of the air-intake and leak-proof structure "is mainly a hard seat block inside the air channel for the linkage rod at the top of the hard movable seat to pass through. The outer peripheral wall of the hard movable seat:- The body is extended by several blocks. The bottom end of the rigid movable seat is provided with a guide rod. Especially, a soft cymbal is integrally formed in the rigid movable seat. The soft body can be pushed by the spring to form an air tightness with the rigid seat block. contact. However, the applicant based on continuous innovation research and development, found that the rigid movable seat of the reference case is formed by using rhenium material to form a soft body-body and insert a guide rod. However, the high-pressure air in the air channel of the pneumatic tool contains water vapor. There is added lubricating oil 'When used-read for a long time, grease often contacts the hard movable seat' causing plastic materials to age and harden, while the hard movable seat is hardened and contracted ', which causes leakage of its adhesion to the soft body. The seam makes the airtightness of the contact between the hard movable seat and the soft body and the hard seat block, and the normal operation of the shirt ring pneumatic tool; M253448 However, because the movable seat and the soft body are formed, the guide rod is also formed in the movable seat. The body is shot and coated, so the soft ^ Qin Chengcheng and the quarter shell body, the movable seat loses effectiveness due to material changes, often the entire scrap 'material costs are immediately discarded, which is a pity. [New content] = The creator has the problem that the design still exists, so he has developed a pneumatic guard and pq moving door device to design a simple and effective design that provides a detachable combination design. It can be used as the main creative purpose to replace the individual components that are relatively inexplicable with 'no overall scrapping' required. In order to achieve the aforementioned object of the invention, the technical slave system used in this creation is to provide a valve device for a pneumatic tool. The system includes: a seat, the wide seat is a hollow metal, and the axial end is a ring. The other end is a protruding part, a sinker is formed in the ring part, and a through-hole and a perforation communicating with the sinker are formed in the protruding part; and-a leak-preventing ring, which is a soft ring body for plugging and combining in the valve seat In the sink, the end face of the leakage ring is recessed-shallow groove; and. -The valve stem has two ends, one end of which is used to penetrate the body of the ring portion of the valve seat, and the other end is sequentially formed to abut against the shoulder of the shallow groove of the leakage ring, and is used to pass through The upright portion 'in the leak-proof ring is used to be fixed to the perforated tip portion, and the shaft tip portion is assembled in the perforation in a tight fit manner. … The effect that can be obtained in this creation is that the valve seat is provided with a sink to prevent leakage, and the valve stem is provided with a shoulder to press against the leakage ring to ensure positioning, and the shaft tip is inserted in a tight fit. Installed in the perforation of the extension, in the normal state, the seat and the valve rod press the leak-proof ring; the t position is stable, so that the leak-proof ring is positioned at the valve seat :, to ensure that the leak-proof% provides air-tight contact without walking and falling off The stability of the M253448 ring requires Γ ::: to provide the advantages of detachable I and combination. 'If the leak stop needs to be replaced, as long as the valve stem is driven back through the perforation with a mechanical tool, the leak stop ring can be updated.' Metal or weather-resistant and chemically stable materials are used, so the leak-tight ring is damaged without the need to scrap the whole group, so it saves a lot of cost, and it is easier to inspect and maintain the airtight effect of the valve. [Embodiment] Figure, 〇) 0) This creation is a valve device of a pneumatic tool. Please refer to the first creation of the valve system including-valve seat (1 ◦),-leak-proof ring, a valve stem (3 0) The valve seat is connected to the leakage ring (20) 'through the valve stem (30). The preferred embodiments are further described below. To two (2 (1) The valve seat (" Ini-V 丄 υ) 'can be made of metal or a material with good chemical stability and high weather resistance. It is designed to form a hollow body with an axial end as a ring ( 1 1) 'Yuai Bu (1 1) Xi Buxiang 丨 _ J Xi Bu side spacer ring protrusion number blocking protrusion (1 1 1), the axial direction is the outer ridge small; /, Yikou p (1 1) The protruding portion (1 3), the ring portion (1 1) forms a sinker (1 tw ^), and the protrusion (1 3) forms an inner diameter smaller than the sinker (12) and is a perforation penetrating through the king Wang Bei 14); and the leakage stop ring (20), a shallow groove (2 1) is recessed on the end face opposite to the valve seat (10 and the leakage ring (20) is a soft ring body);
