Description
Technical Field
The utility model relates to a five mouthfuls of four-way valves that steerable material passes through, concretely relates to prevent five mouthfuls of controllable formula four-way valves of long-pending material of material.
background
In a multi-channel discharging or distributing valve for controlling the material to enter and exit, the movement of a valve rod is generally controlled through an actuating mechanism, and the valve rod moves to drive a valve core to move, so that the opening and closing of different valves are controlled to realize the discharging or sealing among different channels. Patent CN9222671.7 discloses a three-position five-way valve, which controls the flow of different fluids by means of two-by-two communication of five inlets and outlets on the valve housing through the rotational positioning of a valve core with two independent channels, but the rotatable valve core in the five-way valve body is 90 degrees with the inlets and outlets, which affects the production efficiency for poor-flowability objects and easy material accumulation or blockage inside the valve body. Patent CN201621471338.6 has reported that a novel five-way valve passes through the valve, and the upper and lower of fan-shaped post through control mechanism to the control is advanced the switching on of pipe and exit tube, does not need extra installing the ooff valve additional, directly controls the switching in each shut through the five-way valve, nevertheless should pass through the inner structure of valve comparatively complicated, when being used for some graininess materials to pass through, the long-pending material of material or even putty phenomenon easily takes place equally.
When current prior art conventional valve is applied to graininess object, because the medium mobility that passes through is relatively poor, long-pending material appears in inside easily in the granule material, not only influences the leakproofness of valve, and more importantly can take place to mix with other materials at the long-pending material of valve body inside, arouses the compounding of different products, and then influences the material purity in the storehouse body.
SUMMERY OF THE UTILITY MODEL
the utility model aims at providing a prevent long-pending material five port valves of cross to overcome the defect that prior art exists.
The anti-material-accumulation four-way five-port valve comprises four discharge ports, a feed port, a valve body, a valve core with a valve core channel and a rotary actuating mechanism;
The four discharge ports are respectively and horizontally arranged at the lower side part of the valve body, and the feed ports are arranged at the upper part of the valve body;
The valve core is arranged in the valve body, the lower part of the valve core is connected with one end of the valve rod, and the other end of the valve rod penetrates through the valve body to be connected with the rotary actuating mechanism;
The inlet of the valve core channel is communicated with the feed inlet, and the outlet of the valve core channel and the discharge outlet are positioned on the same horizontal line;
The utility model discloses a prevent long-pending material five port valves of cross has following advantage:
(1) the inside passageway of case is direct to be connected with business turn over material mouth, and when passing through the material, the material does not connect the cavity of valve inside, can not produce the long-pending material condition of dead point in the valve inside, and the material that reaches each discharge gate simultaneously also can not be with the material compounding in other valves.
(2) the channel angle inside the valve core is an obtuse angle, so that the resistance of materials passing through the valve body is effectively reduced, and the phenomenon of material accumulation is further reduced.
(3) the sealing spring mechanisms on the valve body and the valve seat realize the sealing of the valve and prevent the material from being oxidized due to the contact with air to influence the product quality.
