Abstract
The invention discloses an environment-friendly flow control valve of a powdery material packing machine. The environment-friendly flow control valve comprises a valve element, a transparent cap, a blank cap and a valve body. A valve element head is arranged on the valve element, and an oil seal and a bearing are further arranged at the upper position and the lower position of the valve element head respectively. The valve body is composed of an upper valve body and a lower valve body, the transparent cap is mounted on the upper valve body through a screw, the blank cap is mounted on the lower valve body through a screw, a cavity is formed in the upper valve body, a feeding control opening and a discharging control opening are formed in the left side and the right side of the cavity respectively, and a valve element control hole is formed in the valve element head of the valve element. The environment-friendly flow control valve of the powdery material packing machine is simple in structure, precise in flow control, free of leakage, safe and reliable, environmentally friendly, practical, convenient to operate, and long in service life. The environment-friendly flow control valve of the powdery material packing machine can be widely used in packing machines of powdery materials such as cement.
Description
Technical field:
The present invention relates to flow control valve, particularly a kind of flow control valve for powder material package machine.
Background technique:
The existing flow control valve for powder material package machine (as: cement-packing plant) adopts slide plate and board plug structure to adjust the flow of wrapping machine discharging more, adopt this structure, on the one hand, in the packaging process of conducting powder shape material, easily cause material from leakage and befouling environment, and endanger the healthy of operator, on the other hand, control action inaccuracy due to valve, often causes error in dipping.
Summary of the invention:
Object of the present invention be just to provide a kind of simple in structure, flow control accurately, without leaking, safe and reliable, environmental protection is practical, the environment protection type powder material package machine flow control valve of easy to operate, long service life.
For achieving the above object, a kind of environment protection type powder material package machine of the present invention flow control valve comprises spool, transparent cover, stifle and valve body, described spool is provided with valve core head, upper-lower position at valve core head is also respectively equipped with an oil sealing and a bearing, described valve body is comprised of upper valve body and lower valve body, described cover screw is installed on upper valve body, described vexed cover screw is installed on lower valve body, described upper valve body is provided with cavity, on two limits, left and right of cavity, be respectively equipped with charging and control mouth and discharging control mouthful, the valve core head of described spool is provided with spool control hole; Coordinating between described valve core head and cavity on upper valve body adopts Spielpassung; Described valve core head is cylinder valve core print; Described valve core head is half-cylindrical valve core head.
The present invention is because the upper-lower position at valve core head is respectively equipped with an oil sealing and a bearing, valve core head adopts cylindrical or half-cylindrical, and coordinating between valve core head and cavity on upper valve body adopts Spielpassung, adopts after such structure, on the one hand, sealability has obtained very large improvement, can guarantee that granular material does not leak, on the other hand, in the process that granular material is packed, by the accurate control to spool, can easily realize the accurate control to granular material flow.
Accompanying drawing explanation:
Fig. 1 is the sectional view of first embodiment of a kind of environment protection type powder material package machine of the present invention flow control valve;
Fig. 2 is the sectional view of another embodiment of a kind of environment protection type powder material package machine of the present invention flow control valve.
Embodiment:
A kind of environment protection type powder material package machine flow control valve shown in Fig. 1 comprises spool 1, transparent cover 2, stifle 7 and valve body 6, spool 1 is provided with valve core head 12, upper-lower position at valve core head 12 is also respectively equipped with an oil sealing 5 and a bearing 4, valve body 6 is comprised of upper valve body 61 and lower valve body 62, transparent cover 2 use screws 3 are installed on upper valve body 61, stifle 7 use screws 3 are installed on lower valve body 62, upper valve body 61 is provided with cavity 613, on two limits, left and right of cavity 613, be respectively equipped with charging and control mouth 612 and discharging control mouth 611, the valve core head 12 of spool 1 is provided with spool control hole 11.Coordinating between valve core head 12 and cavity 613 on upper valve body 61 adopts Spielpassung.Valve core head 12 is cylinder valve core print 121.
In Fig. 2, provided the another kind of embodiment of spool, valve core head 12 is half-cylindrical valve core head 122.
During work, rotary spool 1, when the spool control hole 11 on the valve core head 12 of spool 1 and the charging control mouth 612 on valve body 6 have intersection, valve open, now can carry out the filling of granular material, and intersection is more, and its flow is larger; When the spool control hole 11 on the valve core head 12 of spool 1 is controlled mouth 612 without intersection with the charging on valve body 6, valve closing, stops the filling of granular material.
