Abstract
The invention discloses a screw rod feeding gate device which comprises a valve body, a valve plate, a bi-directional screw rod, a nut, pin shafts, connecting rods and a hand wheel; the hand wheel is connected with the bi-directional screw rod; the bi-directional screw rod is connected with the nut; the nut is connected with the connecting rods; the valve plate is connected with the valve body through four connecting rods; and the pin shafts for fixation are arranged on the connecting rods. The screw rod feeding gate device can effectively and reliably lift the valve plate, the screw rod and the nut are self-locking, so that no self-locking devices need to be added, the structure is simple, and the cost is low.
Description
Technical field
The present invention relates to the valve system in the material conveying process, be specifically related to a kind of screw rod gate device.
Background technology
The widespread use in the material conveying process of industries such as electric power, metallurgy, coal, chemical industry, mine, harbour, cement of gate device; Because gate is the manual gear rack gear arrangement in the conventional confguration; The cost of rack-and-gear is high; The anchor fitting of manual gear is complicated, need add locked device in addition, thereby cause whole cost very high.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of simple and easy, reliably, screw rod gate device cheaply.
Technical scheme of the present invention is: a kind of screw rod gate device; Comprise valve body, valve plate, reverse-flighted screw, nut, bearing pin, connecting rod and handwheel; Said handwheel is connected with reverse-flighted screw, and reverse-flighted screw is connected with nut, and nut is connected with connecting rod; Said valve plate is connected with valve body through four connecting rods, and connecting rod has been provided with the bearing pin of fixation.
Valve plate of the present invention is connected through four connecting rods with valve body, drives nut (positive and negative a pair of) during reverse-flighted screw rotates and moves dorsad along screw axial, causes that the connecting rod angle changes the position that changes valve plate and valve body.
The invention has the beneficial effects as follows: 1, can realize the function that valve plate goes up and down effectively, reliably; 2, bolt and nut has self-locking performance, need not to add in addition self-locking device; 3, simple in structure, cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
