Embodiment Construction

[0020] Figure 1 to Figure 4 As shown, an embodiment of the present invention includes: end cover 1, valve body 2, left valve seat 3, double-ended poppet valve core 4, right valve seat 5, electromagnet 6, baffle plate 7, return spring 8, can Adjust spring seat 9, armature push rod 10, bobbin 11, coil 12, electromagnet housing 13, etc. The spool is a double-ended cone valve structure with a tapered shape. Back-moving spring 8 is positioned by the inner hole of baffle plate 7 and adjustable spring seat 9. When installing, first pass the right connecting rod of the double-ended poppet valve core 4 through the inner hole of the right valve seat 5, and after the armature push rod 10 of the electromagnet 6 is sealed by the gray ring, it is connected with the double-ended poppet valve. The connecting rod on the right side of the core 4 is tightly connected by threads, the A port communicates with the collection bottle with a one-way valve at the end, the collection bottle communica...

Abstract

A two-position three-way electromagnetic reversing valve for deep-sea collection comprises an end cap, a valve body, a left valve seat, a double-end conical valve core, a right valve seat, an electromagnet and the like. Openings A, B and C are formed in the valve body, the end cap, the valve body and the electromagnet are sequentially connected, the left valve seat, the double-end conical valve core and the right valve seat are sequentially disposed inside the valve body from left to right, a conical valve hole is arranged in each of the left valve seat and the right valve seat, an annular groove is formed in each lateral cylindrical face, multiple uniformly-distributed connecting holes are formed in each annular groove and communicated with the conical valve holes inside the respective valve seats, a connecting groove on the double-end conical valve core communicates a left-side inner cavity between the left valve seat and the double-end conical valve core with a right-side inner cavity between the double-end conical valve core and the right valve seat, the double-end conical valve core is connected with an armature pushing rod penetrating the right valve seat, horizontal moving of the double-end conical valve core is realized by controlling a coil to be powered on and off, the opening A and the opening B are externally connected with deep-sea high pressure, the opening A is externally connected with a water incoming one-way valve, and the opening C is communicated with low pressure.

Description

technical field [0001] The invention relates to a direction control element in a deep-sea seawater collection device, which belongs to the valve category, and is mainly suitable for seawater, and is also suitable for the direction control valve of a medium-high pressure water depth collection device with fresh water, high water base, etc. as the working medium, and is used in deep sea During the seawater collection process, the pressure holding, seawater collection and depressurization of the collection bottle are carried out. Background technique [0002] With the rapid development of paleoceanography, marine ecology, marine geology and other disciplines, the collection of deep-sea seawater samples is becoming more and more important, and at the same time more and more requirements are put forward for the collection of seawater samples. Deep-sea seawater collection is mainly used to collect seawater samples at different depths on the ocean cylinder, and then conduct researc...
