Abstract
The utility model relates to a granular slurry sluice valve, which belongs to the technique of granular slurry sluice valves. The technical products are mainly used for switching on and off the slurry conveying conduit. The utility model is characterized in that a rising stem parallel type rigidity single disc sluice valve is adopted; the sealing face of the rising stem parallel type rigidity single disc gate valve is doubly sealed with the valve body; the valve body is abrasion resistant. The utility model has the advantages of simple structure and low cost, and the service life of the utility model is increased to 11-21 times as compared with the service life of the original old type sluice valve.
Description
The utility model relates to the mechanical aspects design, and concrete what is said or talked about is a kind of particle mud gate valve, is mainly used in the open and close of slurry transportation pipeline.
At present, carry on the industry at slurry, gate valve still replaces with common valve, under of the effect of particle mud in high pressure, during by this valve, can cause very big erosive wear to the sealing surface and the valve body of valve, make this valve the life-span on the slurry transportation pipeline only about 10-30 days.
The purpose of this utility model designs a kind of compression resistance, wear-resistant, has long particle mud gate valve in working life.
Purpose of the present invention realizes by following technical solution: display unit (position limit switch) is threaded with the hydraulic jack employing and adopts bolt to tighten with valve body, sewage draining exit 6 is connected with the valve body bolt, be connected with flange between creeping flange seat and the valve body, adopt transition fit between creeping flange seat and the creeping flange; The connection of described sealing configuration is that valve body 3 is connected with flange with external flange, and folder one flashboard 5 between two external flanges 4 supports seal ring 10 and pressurize seal ring with water-fast gluing connecing;
Structural type is designed to open stem parallel type rigidity Single disc, and sealing surface and Sealing is hidden in valve body, and the passage of whole valve is the pipeline straight-through type, makes slurry by valve, and the wearing and tearing of valve body are equaled the wearing and tearing of slurry to pipeline.Described seal form is that recessive type is dual from motive sealing, seal carrying out pressurize between valve seat and the flashboard with Yx type pressurize seal ring near latus rectum one side, which face pressurized of flashboard no matter, the lip limit of Yx RunddichtringO can be opened automatically, guarantee the sealing between flashboard and the valve seat, during for pressurized of assurance flashboard, the gap between flashboard and the valve seat is reasonable, outside the Yx RunddichtringO, added again and supported seal ring together, guaranteed the proper functioning of Yx type pressurize seal ring.
The teflon of sealing material use high abrasion is made the support seal ring, uses high abrasion, and high withstand voltage polyether types of polyurethane rubber is made Yx type pressurize seal ring.
In flange one side that gate valve connects with pipeline, design a slip joint and can make valve easy to loading and unloading, in time eliminate the Installation Stress of pipeline, but and the axial linear change of extraction duct and the variation of angle radially.
Good effect of the present utility model owing to adopt the double seal effect to reach certain degree, can reach 2 years～3 years at seal aspect, than original raising 10-30 doubly working life.
Fig. 1 is the utility model structural representation.
This model utility is made up of following component: 1 gate valve switch display unit (containing position limit switch), 2 hydraulic jacks, 3 valve bodies, 4 external flanges, 5 flashboards, 6 sewage draining exits, 7 creeping flange seats, 8 creeping flanges, 9 bolts.
Scyewed joint is all adopted in the connection of each parts in this model utility, connects with outer pipeline to adopt flange to connect.
Fig. 2 is the utility model seal style schematic representation.
10 support seal ring, 11 pressurize seal rings.
More than two parts be to form with connecting of flange with water-fast glue is bonding.
Provide specific embodiment below:
A, structural type are elected open stem parallel type rigidity Single disc as, and flashboard and valve body improved, no matter make valve sealing surface and Sealing when opening and closing can not be exposed in the slurry, the passage of whole valve is the pipeline straight-through type after unlatching, and the slurry by valve equals the wearing and tearing of slurry to pipeline to the wearing and tearing of valve body.
B, seal style are that recessive type is dual from motive sealing, near latus rectum one side Yx type pressurize seal ring, to carrying out the pressurize seal ring between valve seat and the flashboard, to carrying out the pressurize sealing between valve seat and the flashboard, no matter which face pressurized of flashboard, the lip limit of Yx RunddichtringO can be opened automatically, guarantees the sealing between flashboard and the valve seat.During for pressurized of assurance flashboard, the gap between flashboard and the valve seat is reasonable, in the Yx RunddichtringO outside, has added again and has supported seal ring together, has guaranteed the proper functioning of Yx type pressurize seal ring.
C, sealing material: make the support seal ring with the teflon of high abrasion, make Yx type pressurize seal ring with the high withstand voltage polyether types of polyurethane rubber of high abrasion, sealing effect is higher than Japanese like product.
D, driving mode have been selected hydraulic pressure and manual two kinds for use, and safe and reliable, cost is low, for hydraulic valve, can control separately and team control, has at hydraulic parts under the situation of damage, changes relevant part and just can normally move.
One side of e, the flange that connects with pipeline at gate valve designs a Telescopic short piece, can make valve easy to loading and unloading, in time eliminates the Installation Stress of pipeline, but and the axial linear change of extraction duct and angle radially change.
Claims (2)
1, a kind of particle mud gate valve, described product is the single gate valve of a kind of open stem parallel type rigidity, it is characterized in that the employing of display unit (position limit switch) and hydraulic jack is threaded and adopt bolt to tighten with valve body, sewage draining exit 6 is connected with bolt with valve body, be connected with flange between creeping flange seat and the valve body, adopt transition fit between creeping flange seat and the creeping flange; The connection of described sealing configuration is that valve body 3 is connected with flange with external flange, and folder one flashboard 5 between two external flanges 4 supports seal ring 10 and pressurize seal ring with water-fast gluing connecing;
