Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as figure 1 , figure 2 As shown, the two-position two-way bidirectional pressure control valve of the present invention includes a valve body 14, a valve cover 4 and a base 11 arranged at the upper and lower ends of the valve body 14, and the above-mentioned components constitute the main structure of the present invention.
[0019] The valve body 14 is longitudinally provided with a valve cavity A10, and a valve stem 9 is movable up and down in the valve cavity A10. The valve body 14 on both sides of the valve cavity A10 is correspondingly provided with an air port A15 and an air port B7. A sealing ring 8 is provided on the valve stem 9 between the air port A15 and the air port B7. It should be noted that when the sealing ring 8 is located between the air port A15 and the air port B7, the present invention is in an initial state.
[0020] The upper par...

The invention relates to the technical field of sewing machine components, in particular to a two-position two-way bidirectional pressure control valve. The bidirectional pressure control valve comprises a valve body, as well as a valve cover and a base which are arranged at the upper end and the lower end of the valve body, wherein a valve cavity A in which a valve rod capable of moving up and down is arranged is longitudinally formed in the valve body, an air port A and an air port B are correspondingly formed in the valve body on two sides of the valve cavity A, and a seal ring is arranged on the valve rod between the air port A and the air port B; an accommodating cavity is transversely formed in the inner upper part of the valve cover, an air tap A and an air tap B are respectively arranged at two ends of the accommodating cavity, a valve core is arranged between the air tap A and the air tap B, a valve cavity B is formed at the inner lower part of the valve cover and communicated with the accommodating cavity, the valve cavity B and the valve cavity A are coaxially arranged, a piston is arranged in the valve cavity B and propped against the upper end of the valve rod, and a reset spring is arranged between the lower end of the valve rod and the base; the air port A is communicated with the air tap A, and the air pot B is communicated with the air tap B. The two-position two-way bidirectional pressure control valve is compact in structure, reasonable in arrangement and high in airtightness and achieves bilateral control.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a two-position two-way bidirectional pressure control valve. Background technique [0002] Valves are widely used in fluid control in various technical fields, and the two-position two-way valve is one of them, which is well known. At present, two-position two-way valves mostly adopt one-way control, that is, a single inlet and a single outlet, and generally the inlet and outlet are fixed, so when it is installed and used, it must be installed in strict accordance with the orientation of the inlet and outlet, which greatly limits its application field and scope of application. Contents of the invention [0003] The object of the present invention is to provide a two-position two-way bi-directional pressure control valve with compact structure, reasonable arrangement and good sealing performance in view of the defects and deficiencies of the prior art. [0004] To achieve the a...
