Abstract

The present invention relates to fluid direction changing technology. The basic structure of the fluid direction controller includes one valve core comprising one truncated conic core and one integrated middle shaft, and one valve body comprising one casing, one integrated shaft shell and one rotating handle. The fluid direction change is completed by turning the rotating handle by 90 deg. Compared with available similar valve, the present invention has the advantages of small volume, simple structure, easy operation, and wear resisting rubber ring in the valve core.

Description

Integrated two-position five-way fluid direction selecting controller.

The invention belongs to the fluid reversing valve technology field, basic structure is made up of a changeover valve core and an outsourcing valve body, sees Fig. 1; And spool is made up of a round platform core and a disjunctor axis, sees Fig. 2; Valve body adds turning handle by a valve casing and a disjunctor axle housing and forms, and sees Fig. 3 (right side is looked) and Fig. 4 (left side is looked).Cushion rubber is sealed in solid stain " ● " expression among the figure.

Spool four

holes

1,2,3,4 are orthogonal, adjacent 90 ° of angles, and its mesopore 3 is the empty hole of not revealing the exact details, and also adds cushion rubber and plays and cover other logical bottom outlet effect (see figure 2).Hole 5, hole 6 communicate with hole 1 in frustum cone side, and form spool (seeing Fig. 2 ') with the axis disjunctor that contains hole 7; Valve body six holes 1 ', 2 ', 3 ', 4 ', 5 ', 7 ' relative position is shown in figure one.

Working principle: when the half-twist angle of turning handle 6 ' to the right, see right elevation 3, fluid by outward through the hole 5 ' enter in the machine, again through the hole 5, hole 1, hole 4 ' in machine, finishing circulation flow back to hole 1 ', hole 2, hole 4, hole 3 ', hole 2 ' go out bodies for purifying fluids; When the half-twist angle of turning handle 6 ' left (seeing left view 4); Fluid from the hole 5 ' enter body, through the hole 6, hole 1, hole 1 ' in machine, finishing circulation flow back to hole 4 ', hole 4, hole 2, hole 2 ', hole 3 ' recoil discharges the filthy fluid that commutates.

The present invention compares with split type two-position five-way recoil valve, except that having the little 3. easy to operate advantage of 2. volume 1. simple in structure, also has the advantage that the attached conventional apron antifatigue loss of button is but decreased at utmost point antifriction more than 30,000 times on the spool, so the present invention has very strong practicability.About the extremely strong reason of conventional apron antifatigue loss on the spool, other has in the model utility technology newspaper patent is auspicious and states, and the present invention does not explain.

Claims

1, a kind of fluid reversing valve mechanism with other new feature of similar inventions phase region is: (1) five-way road frustoconic shape spool, and its mesopore 3 is the empty hole of not revealing the exact details, the hole effect of covering when playing commutation, all reveal the exact details in other five duct; (2) valve body is the hollow round platform in five-way road, built-in frustoconic shape spool, externally fluid enters under the situation of body hole 5 ' constant, drives spool by rotating shaft and back and forth rotates between 90 ° of angular regions, force turnover fluid duct positioning in spool and the valve body, realize that fluid gains the outflow body.

2, according to the described this valve mechanism of claim one, its basic feature is: four holes 1,2,3,4 on the design plane of (1) integral type spool, adjacent in twos 90 ° of right angles, its mesopore 3 is the empty hole of not revealing the exact details, the purpose that also adds cushion rubber is, after spool turns over 90 °, play the purpose of covering other duct of revealing the exact details; (2) spool, frustum cone side institute perforate 5, hole 6 communicates and simultaneously and hole 1 vertical threeway; When valve body hole 5 ' when communicating with spool bore 5, spool bore 6 stops water flowing work; Otherwise after changeing 90 °, when valve body hole 5 ' when communicating with spool bore 6, spool bore 5 quits work.

So design reaches the fluid reversing of finishing peak rate of flow in the volumetric spaces of minimum, and extremely strong popularization practicability is arranged, and please give the emphasis encipherment protection.
