To above-mentioned problem, in order to improve the availability factor of case, increase the sealing performance of equipment, the utility model provides an eight quick-witted case.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an eight quick-witted case has that the flexibility is good, sealing performance is strong and the advantage that availability factor is high, has solved the problem among the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an eight head quick-witted case, includes the case body, the case body includes case main part, circular arc groove, straight flute, pivot and connecting portion, is equipped with circular arc groove and straight flute in the case main part, and the side in the case main part is installed in the pivot, and another side in the case main part is connected to connecting portion.

Furthermore, the valve core main body, the arc groove, the straight groove and the connecting part are of a welded integral structure.

Furthermore, eight arc grooves and eight straight grooves are arranged.

Further, install first elastic sealing ring on the inner wall in circular arc groove, install second elastic sealing ring on the inner wall in straight groove.

Furthermore, the caliber of the arc groove is consistent with the caliber of the first elastic sealing ring, and the caliber of the straight groove is consistent with the caliber of the second elastic sealing ring.

Furthermore, the valve core main body is made of stainless steel.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model provides an eight quick-witted case through adopting straight flute and circular arc groove design for the resistance when the case reduces the material circulation, porous integration dismantles simple to operate, and, can put through different passageways through turned angle, and the flexibility is strong, and the practicality is big.

2. The utility model provides an eight quick-witted case installs first elastic sealing circle on the inner wall in circular arc groove, installs second elastic sealing circle on the inner wall in straight flute, has guaranteed the sealing performance of commentaries on classics valve, because the sealing washer setting is inside the case main part, when having avoided the case installation, the yield decline defect that rubber seal was led to by wearing and tearing reduces product manufacturing cost.

3. The utility model provides an eight quick-witted case, the preparation material of case main part chooses for use stainless steel material, and corrosion resisting property is good, and intensity is big, has prolonged the life of equipment.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1. a valve core main body; 2. an arc groove; 3. a straight groove; 4. a rotating shaft; 5. a connecting portion.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an eight-head valve core comprises a valve core body, the valve core body comprises a valve core main body 1, an arc groove 2, a straight groove 3, a rotating shaft 4 and a connecting part 5, the arc groove 2 and the straight groove 3 are arranged on the valve core main body 1, eight arc grooves 2 and eight straight grooves 3 are arranged, the rotating shaft 4 is arranged at one side end of the valve core main body 1, the connecting part 5 is connected with the other side end of the valve core main body 1, the arc groove 2, the straight groove 3 and the connecting part 5 are of a welded integral structure, a first elastic sealing ring is arranged on the inner wall of the arc groove 2, a second elastic sealing ring is arranged on the inner wall of the straight groove 3, the caliber of the arc groove 2 is consistent with that of the first elastic sealing ring, the caliber of the straight groove 3 is consistent with that of the second elastic sealing ring, the sealing performance of a rotary valve is ensured due to the sealing ring arranged inside the valve core main body 1, when the valve core is installed, the yield that rubber seal was led to by wearing and tearing descends the defect, reduces product manufacturing cost, through adopting straight flute and circular arc groove design for the case reduces the resistance when the material circulates, and porous integration dismantles simple to operate, and, can put through different passageways through turned angle, and the flexibility is strong, and the practicality is big, and the stainless steel material is chooseed for use to the preparation material of case main part 1, and corrosion resisting property is good, and intensity is big, has prolonged the life of equipment.
