Description

Rotary feeding valve

Technical Field

The utility model relates to a rotatory feed valve technical field especially relates to a rotatory feed valve.

Background

The feed valve can satisfy the feeding and can satisfy sealed device of requirement again one kind, can effectively avoid getting into the material behind the container and outwards volatilize through the feed inlet, and specially adapted toxic material's feeding, at present, to the great material of large granule or length, difficult unloading when passing through the feed valve leads to the feed valve to block up, blocks up, is unfavorable for the continuous operation of feed valve to lead to the feed valve wearing and tearing easily after long-term operation, be unfavorable for the maintenance of its gas tightness.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the prior art has a rotary feed valve wear speed block and has insufficient air tightness, and providing a rotary feed valve.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design provides a rotary feeding valve, including valve body and case, the inside spherical cavity that has opened of valve body, the case is installed inside the valve body, open the both sides that the valve body is relative has the feed inlet, the stock chest has all been opened to the both sides that the case is relative, the stock chest with the feed inlet is located same horizontal plane, the pivot is installed to case one side, pivot one end is stretched out the pivot outside is installed driving motor, the striker plate is installed in the case outside, the valve body includes inoxidizing coating and wearing layer, the wearing layer with the spout has all been opened to the both sides that the feed inlet meets, the spout with install sealing mechanism between the striker plate.

Preferably, the sealing mechanism comprises a sealing plate, a limiting block and a spring, the spring is installed inside the sliding groove, the sealing plate is fixed to the top of the other end of the spring, and the limiting block is installed on the outer side of the sealing plate.

Preferably, the limiting block is an elastic block, and the bottom of the limiting block is connected with the striker plate.

Preferably, the protective layer is a high-temperature resistant material plate layer.

Preferably, the driving motor is a stepping motor.

The utility model provides a pair of rotatory feed valve, beneficial effect lies in: utilize the driving motor who installs in the valve body outside to drive the case and rotate, conveniently accomplish rotatory feeding operation to wear resistance and the life of device are improved through setting up of wearing layer and striker plate, the sealing performance of device is improved through sealing mechanism.
