Abstract
The invention discloses a split type sluice valve with filter screens and belongs to the field of valves. The split type sluice valve comprises a valve stem, a valve seat and a sluice plate, the valve body is divided into a primary valve and a secondary valve, and the sluice plate and the valve seat are arranged in the primary valve, the secondary valve is connected with the primary valve in a threaded manner, one end of the secondary valve extends into the primary valve, the end of the secondary valve extending into the primary valve is provided with two filter screens, and a blowdown storage sink is arranged between the filter screens. The bottom of the blowdown storage sink is provided with blowdown holes and plugs matched with the blowdown holes. The plugs are provided with annular grooves for arranging sealing rings. Impurities of fluid medium can be effectively reduced, and service life of the sluice valve is prolonged.
Description
Technical field
The present invention relates to valve field, specifically a kind of split type band filter screen gate valve.
Background technique
Gate valve makes open-shut device with flashboard and move along valve seat axes normal direction, to realize the valve of switching motion.Gate valve can only standard-sized sheet and complete shut-down, and open-shut device is flashboard, moving direction and flow direction perpendicular, square I-shaped gate valve two sealing surfaces form wedge shapes, key groove is different with valve parameter.
In the prior art, the valve seat of most gate valve processes through butt welding processing in the chamber of valve body, do not have special instrument to be very difficult to take out.If medium fluid contains certain impurity, the metallic sealing section formed by machine flinishing very easily produces wearing and tearing, and once there is poorly sealed defect, many users only have replacing gate valve, then scrap with the gate valve changed.The economic loss caused is large, cost of idleness.
Summary of the invention
The invention provides a kind of split type band filter screen gate valve, be intended to the impurity reducing flowing medium, improve the physical life of gate valve.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of split type band filter screen gate valve, comprise valve rod, valve seat, flashboard, it is characterized in that: valve body is divided into one-level valve body and secondary valve body, flashboard and valve seat are arranged in one-level valve body; Described secondary valve body is threaded with one-level valve body, and one end puts in one-level valve body; The described secondary valve body port position put in one-level valve body is provided with two-layer filter screen, has sewage-storage trough between two-layer filter screen; Have pollutant exhaust hole bottom described sewage-storage trough, and be provided with the plug with pollutant exhaust hole adaptation; Described plug has the annular groove placing seal ring.
Described valve seat is embedded in one-level valve body.
Described secondary valve body and one-level valve body joint are provided with the protective metal shell of banding.
The length of described protective metal shell can cover pollutant exhaust hole completely.
Described secondary valve body and the one-level valve body connecting thread end are also provided with seal ring near one-level valve body port.
Described seal ring is the sealing O shape circle of nitrile rubber material.
It is fine and closely woven filter screen that described filter screen puts in one-level valve body inner port near secondary valve body, and putting in one-level valve body inner port away from secondary valve body is broad filter screen.
Beneficial effect of the present invention is: first, and valve body is divided into one-level valve body and secondary valve body, and connects with screw thread, achieve the detachability of valve body, split type valve body is also more easily produced.Secondly, be provided with two-layer filter screen in secondary valve body, if filter screen damages, or after residue excessively blocks, secondary valve body can be dismantled and carry out changing and cleaning, convenient and simple.Again, it is fine and closely woven filter screen that filter screen puts in one-level valve body inner port near secondary valve body, putting in one-level valve body inner port away from secondary valve body is broad filter screen, double-deck different filter screen can make contamination precipitation in sewage-storage trough, timing is got rid of from pollutant exhaust hole, realize filtering function, greatly reduce the content of impurity, strengthen the working life of gate valve.Finally, with the joint of protective metal shell banding one-level valve body and secondary valve body, make its structure more stable.
Accompanying drawing explanation
Fig. 1 is split type band filter screen gate valve structure schematic diagram provided by the invention.
Mark in figure: 1 be secondary valve body, 2 be one-level valve body, 3 be protective metal shell, 4 be plug, 5 be valve seat, 6 be flashboard, 7 be valve rod, 8 be seal ring, 9 be sewage-storage trough, 10 be fine and closely woven filter screen, 11 for broad filter screen.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of split type band filter screen gate valve, comprises valve rod 7, valve seat 5, flashboard 6,
Valve body is divided into one-level valve body 2 and secondary valve body 1, and flashboard 6 is arranged in one-level valve body 2, and valve seat 5 is embedded in one-level valve body 2 li.Described secondary valve body 1 is threaded with one-level valve body 2, and one end puts in one-level valve body 2; The port position that described secondary valve body 1 puts in one-level valve body 2 is provided with two-layer filter screen, and it is fine and closely woven filter screen 10 that filter screen puts in one-level valve body 2 inner port near secondary valve body 1, and putting in one-level valve body 2 inner port away from secondary valve body 1 is broad filter screen 11.Sewage-storage trough 9 is had between two-layer filter screen; Have pollutant exhaust hole bottom described sewage-storage trough 9, and be provided with the plug 4 of pollutant exhaust hole adaptation, described plug 4 has the annular groove placing seal ring.Secondary valve body 1 and one-level valve body 2 joint are provided with the protective metal shell 3 of banding.The length of protective metal shell 3 can cover pollutant exhaust hole completely.Secondary valve body 1 and the one-level valve body 2 connecting thread end are also provided with seal ring 8 near one-level valve body 2 port.Seal ring 8 is the sealing O shape circle of nitrile rubber material.
In use, impurity first by broad filter screen 11, then is screened by fine and closely woven filter screen 10, and larger impurity is deposited in sewage-storage trough.Often can remove protective metal shell 3 after a while, expose pollutant exhaust hole, open plug 4 and carry out blowdown.If impurity occurs too much block, or filter screen is damaged, only needs oppositely to twist secondary valve body 1, secondary valve body 1 is separated with one-level valve body 2, carries out cleaning or changing filter screen.Adopt the present invention, structure is simple, practical, being convenient to cleaning and effectively reducing the impurity entering sealing surface while changing, enhances the physical life of gate valve.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
