Abstract

The utility model discloses an ore drawing valve which consists of a valve body, a screw rod, a control hand wheel and a flashboard; wherein, the valve body is of a tubular shape, and one end of the valve body is provided with a flange which is used for being connected with an ore discharge pipeline; the screw rod is horizontally arranged and extends into the valve body from the other end of the valve body, and one end of the screw rod is provided with the control hand wheel and the other end is provided with the metal flashboard; a nonmetal gland bush is arranged on the metal flashboard and is fixed on the metal flashboard by nuts; the front end of the valve body is provided with a metal washer, the aperture of which is consistent with the internal diameter of the ore discharge pipeline, and the valve body is also provided with a jetteau and a clearance hole, wherein, the aperture of the clearance hole is smaller than the internal diameter of the ore discharge pipeline; the ore drawing valve is reasonable in structure, uniform in stress, not easy to be worn and convenient for operation and use, furthermore, the ore drawing valve is not affected by climate, can improve the production efficiency and reduce the maintenance and repair cost.

Description

A kind of ore drawing valve
Technical field:
The utility model relates to a kind of mining machinery tailings discharging device, particularly relates to a kind of ore drawing valve.
Background technique:
In the prior art, the mining machinery that bargh taked, its tailings discharging control valve all is flashboard types, this valve is to come opening and closing row of conduits mine mouth by control and the vertically disposed flashboard of pipeline, there are the following problems to find it in long-term use: 1. the slit around the flashboard is easily stopped up by ore in sand form, easy to clean brings inconvenience for normal the use; 2. the flashboard power effect that is hit makes the flashboard rapid wear, and is difficult for repairing, and increases cost of production; 3. be subjected to climatic impact bigger, particularly in the winter time, the unlatching of gate valve is required great effort very much, and the consumption time is long, easily causes and freezes.
Summary of the invention:
The purpose of this utility model is at the deficiencies in the prior art, a kind of ore drawing valve is provided, technical problem to be solved is to adopt to move horizontally the opening and closing flashboard, the easy to clean ore in sand form, the replacing wear-out part is convenient, this valve arrangement is reasonable, stressed even, not easy to wear, easy for operation, technical solution adopted in the utility model is as follows: this is novel by valve body, leading screw, the control handwheel, flashboard is formed, it is characterized in that valve body is a tubulose, an end is managed orchid, is used for linking to each other with the ore discharge pipeline, leading screw is horizontally disposed with, put in valve body from the other end of valve body, an end of leading screw is the control handwheel, and the other end is provided with the metal flashboard, it on the metal flashboard non-metallic gasket, sealing gasket is fixed on the metal flashboard by nut, and the valve body front end is provided with metal washer, and the aperture of metal washer is consistent with the internal diameter of ore discharge pipeline, also be provided with water orifice and sand removing hole on the valve body, the aperture of sand removing hole is littler than the internal diameter of ore discharge pipeline.
Compared with prior art, the utility model is rational in infrastructure, stressed evenly, not easy to wear, easy for operation, and weatherproof, can enhance productivity, and reduces the maintenance cost.
Description of drawings:
Accompanying drawing is the utility model structural representation
Specific embodiments:
This novel valve body 2 is a tubulose, one end manages blue 11, be used for linking to each other with ore discharge pipeline 10, the valve body inner close fitting flange and is welded with abrasion-resistant metal packing ring 9, the aperture of packing ring and flange aperture, ore discharge pipeline internal orifice dimension unanimity, the other end of valve body is established leading screw 3, and an end of leading screw is control handwheel 4, and the other end is established metal flashboard 5, be fixed with nonmetal sealing gasket 7 on the flashboard, sealing gasket is fixed on the metal flashboard by nut 8, in addition, establishes water orifice 6 on the top of valve body, be used to clear up ore in sand form, sand removing hole 1 is established in the below of valve body, and the diameter of sand removing hole is less than the internal diameter of ore discharge pipeline, when sediment outflow finishes, from the surplus sand of water orifice water horning, throttle down then, the surplus sand of water horning flashboard rear side again, the surplus sand of being cleared up is discharged from sand removing hole together with water.
