Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the utility model provides a pneumatic control two-way valve, which comprises a base 1, a sealing seat 2, a compression spring 3, a sealing compression column 4 and an air source joint 5; two ends of the base 1 are respectively provided with a first through hole, and an inlet and outlet joint 6 is arranged in each first through hole; the top of the base 1 is also provided with two second through holes 11, and each second through hole 11 is communicated with one first through hole; the sealing seat 2 is arranged at the top of the base 1, and a third through hole penetrating to the top of the sealing seat 2 is formed in the position, corresponding to the two second through holes 11, of the bottom of the sealing seat 2; the sealing pressure column 4 is movably inserted into the third through hole, and the compression spring 3 is embedded in the third through hole and sleeved outside the sealing pressure column 4; the air source connector 5 is installed at the top of the sealing seat 2 and communicated with the third through hole, and the air source connector 5 is used for connecting or disconnecting an external air source so as to be matched with the compression spring 3 to drive the bottom of the sealing compression column 4 to be in contact with or far away from the tops of the two second through holes 11.
Wherein, the bottom of the sealing compression column 4 is also provided with an installation groove, and a sealing compression block 41 is also arranged in the installation groove; the top of the sealing seat 2 is also provided with an installation pressing block 21, the top of the installation pressing block 21 is provided with a first installation hole communicated with the third through hole, and the air source connector 5 is installed in the first installation hole; the top and the bottom of the sealing seat 2 are respectively embedded with a first sealing ring 22, the first sealing ring 22 positioned at the top of the sealing seat 2 is positioned between the sealing seat 2 and the installation pressing block 21, and the first sealing ring 22 positioned at the bottom of the sealing seat 2 is positioned between the sealing seat 2 and the base 1; a second sealing ring 12 is further embedded in the inner wall of each access joint 6, and the second sealing ring 12 is located between the access joint 6 and the end of the base 1.
The utility model discloses the theory of operation:
with continued reference to fig. 1 to 3, when the external air source is ventilated, the air pressure generated by the air source will generate a pressure on the sealing pressure column 4, so as to drive the sealing pressure column 4 to descend (at this time, the compression spring 3 is in a compressed state), so that the sealing pressure block 41 at the bottom of the sealing pressure column 4 contacts with the base 1, and further the second through hole 11 is sealed, so that the medium flowing into the first through hole through the inlet and outlet joint 6 can not pass through the position C (fig. 3), and thus the whole two-way valve is in a disconnected state; when the external air source is disconnected, the external air source is driven by the restoring force of the compression spring 3, the sealing pressing block 41 is driven by the sealing pressing column 4 to ascend, at the moment, the sealing pressing block 41 is not contacted with the base 1 any more, the two-way valve at the moment is in a passage state, a medium can flow from the A to the C (shown in the figure 3) and further flows from the C to the B, and further circulation of the medium is realized.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
