Detailed Description
The following describes specific embodiments of the present invention.
As shown in fig. 1 to 3, the breather valve structure for a single-acting pneumatic actuator includes a screw 1, a valve seat 2, an outer sealing member, an inner sealing member, an elastic element, a pressure plate, and a lock nut 7, in this embodiment, the elastic element is a return spring 5, the outer sealing member is a seal ring 8, the valve seat 2 is coaxially connected by an upper valve body 203 and a lower valve body 201 to form an integrated structure, a hexagonal structure is disposed on the lower valve body 201, and the valve seat 2 is conveniently screwed on a spring cylinder body through the hexagonal structure. The outer ring of the lower valve body 201, which is not provided with a hexagonal structure, is provided with an external thread, the upper valve body 203 is provided with a sealing groove 204 and an air outlet 9 which are communicated with each other, the lower valve body 201 is provided with an air inlet 10 and an inner hole 205 which are communicated with each other, and as shown in fig. 6, the air inlet 10 is symmetrically provided with the axis of the lower valve body 201 as the center. One end of the screw 1 penetrates through the sealing groove 204 and the air outlet 9 of the upper valve body 203 and extends into the inner hole 205 of the lower valve body 201, the other end of the screw 1 extends out of the upper valve body 203 and is sleeved with the outer sealing element, and one end of the screw 1 extending into the inner hole 205 is sequentially sleeved with the inner sealing element, the elastic element and the pressing plate 6 and is in threaded connection with the locking nut 7. The pressing plate 6 is in a cross shape, and a through hole for matching with a screw is arranged at the center of the pressing plate 6
As shown in fig. 1 and 2, the inner seal member is formed by combining a first gasket 3 and a second gasket 4, the first gasket 3 and the second gasket 4 are mutually abutted and are both sleeved on the outer ring of the screw 1, and the first gasket 3 is a rubber gasket. The second gasket 4 is a stainless steel gasket.
As shown in fig. 3 to 5, the upper valve body 203 is formed in an integral structure by coaxially connecting a first cylinder 2031 and a second cylinder 2032, and the outer diameter of the first cylinder 2031 is larger than that of the second cylinder 2032. A pair of ribs 202 are further formed along the inner side of the first column 2031, and the ribs 202 are connected to the end surface of the lower valve body 201.
The specific working process of the invention is as follows:
the invention is screwed on the end cover of the spring cylinder, when breathing out, the air pressure in the spring cylinder is larger than the air pressure outside, at the same time, the air presses the pressure plate 6 to compress the reset spring 5, the first gasket 3 and the second gasket 4 move to the sealing surface of the inner hole 205, so that the first gasket 3 blocks the air inlet 10, because the upper valve body 203 and the lower valve body 201 are independent, and the hole diameter of the inner hole of the first gasket 3 and the second gasket 4 is larger than that of the screw 1, as shown in figure 1, the air outlet 9, the inner hole of the first gasket 3 and the inner hole 205 of the second gasket 4 are communicated, and because the pressure plate 6 adopts a cross shape and has a gap 601 to facilitate the communication of the air in the spring cylinder with the outside, thereby facilitating the exhaust, after the air in the spring cylinder is completely exhausted, the reset spring 5 resets, the reset spring 5 presses the pressure plate 6, so that the pressure plate 6 presses the lock nut 7 and drives the screw 1, so that the seal ring 8 can be fitted in the seal groove 204 to close the air outlet 9.
As shown in fig. 2, on the contrary, when inhaling, the air pressure in the spring cylinder is smaller than the outside atmospheric pressure, the outside atmospheric pressure enters through the air inlet 10 and presses the first gasket 3 and the second gasket 4, so that the first gasket 3 and the second gasket 4 compress the return spring 5, after the first gasket 3 and the second gasket 4 move along the axial direction of the screw 1, the air inlet is gradually opened, the air enters the inner hole 205 of the lower valve body 201 through the inner hole gap of the first gasket 3 and the second gasket 4 until the spring cylinder is full of air, and then the return spring 5 returns to close the air inlet 10.
The spring cylinder is simple in structure and convenient to operate, the spring cylinder can be communicated with the outside by utilizing the spring cylinder, the upper valve body and the lower valve body in the valve seat are independently arranged to form an independent air inlet and an independent air outlet, so that the air inlet and the air outlet are not interfered with each other, the spring cylinder has the advantage of low manufacturing cost, and the design cost of enterprises is effectively saved.
The foregoing description is illustrative of the present invention and is not to be construed as limiting thereof, the scope of the invention being defined by the appended claims, which may be modified in any manner without departing from the basic structure thereof.
