Abstract
The utility model discloses a three-way diverter valve core which can realize the improvement of the production efficiency and no leakage with a valve seat. The three-way diverter valve core comprises a valve core rod and a pair of valve core bodies; each valve core body comprises a valve core seat sleeved on the valve core rod and a valve core head; a seal ring is sleeved on the valve core rod between the valve core seat and the valve core head; and the valve core head and the seal ring are fixed on the valve core seat. The valve core body is arranged into split structure, the seal ring is arranged between the valve core seat and the valve core head, hard seal between the valve core and the valve seat is changed into soft seal, and the leakage level is greatly improved, therefore, no leakage can happen between the valve core and the valve seat; in addition, the requirement on the precision for processing and assembling is lowered, and the production efficiency is improved.
Description
Technical field
The utility model relates to spool, refers more particularly to three-way flow divider valve core.
Background technique
As shown in Figure 1, the present three-way flow divider valve core that uses, its structure comprises: valve core rod 1 and a pair of valve core 2 that is sleeved on the valve core rod 1.Valve core 2 and the seal form between the valve seat in this spool are hard sealings, want to improve sealing effect, reduce leakage rate, just must be under the condition of the machining accuracy that guarantees valve core 2 and valve seat, by carefully grinding valve core body 2 and valve seat patiently, make valve core 2 and valve seat reach linear sealing, improve the sealing grade.The sealing configuration of this spool and valve seat makes process of manufacture very complicated, inefficiency; And can not accomplish not have leakage between spool and the valve seat.
The model utility content
A technical problem to be solved in the utility model is: provide a kind of and enhance productivity, and can accomplish and valve seat between leak free three-way flow divider valve core.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: three-way flow divider valve core, comprise: valve core rod and a pair of valve core, each valve core comprises: be sleeved on valve core case and valve core head on the valve core rod, also be set with seal ring on the valve core rod between valve core case and valve core head, valve core head and seal ring are fixed on the valve core case.
Offer at least two assembling tapped holes on the described valve core case, be respectively arranged with the pilot hole that matches with the assembling tapped hole accordingly on described valve core head and the seal ring, valve core head and seal ring are by uniform being bolted on the valve core case.
The beneficial effects of the utility model are: the utility model is arranged to valve core to comprise the split-type structural of valve core case and valve core head, and between valve core case and valve core head, seal ring is set, hard sealing between spool and the valve seat has been become soft seal, improved leakage class greatly, made not have between spool and the valve seat and leak; And, reduced processing and assembling to the requirement of precision, improved manufacturing efficiency.
