Abstract
The invention relates to the particle material medium conveying technical filed, in particular to an on-line overhaul high-pressure powder feeding valve, which comprises an upper valve body, a seal ring, a spherical surface bell valve plate, a connecting rod assembly, a main shaft, a driving mechanism, a lower valve body, a flange connecting the upper valve body and the lower valve body, and a clamping plate and bolts fixing the seal ring. The invention is characterized in that: a hand hole is arranged on the side face of the upper valve body, and a hand hole seal cover is arranged on the hand hole. The seal ring adopts a polyamide fiber canvas reinforced rubber seal ring. With the hand hole and hand hole seal cover arranged on the side face of the upper valve body, valve overhaul at the home position on the feeding pipeline is realized, thereby greatly reducing overhaul time. The polyamide fiber canvas reinforced rubber seal ring greatly improves the mechanical strength and wear resistance, thereby remarkably prolonging service life, and not only improving the reliability and operating performance of the valve, but also reducing maintenance workload.
Description
Technical field
The present invention relates to granule materials medium transport technical field, particularly a kind of on-bne repair high-pressure powder-type baiting valve.
Background technique
At present the structure of the widely used powder-material laying-off valves of industry such as metallurgy, chemical industry, coal, harbour is as described in the novel ZL972477225 of practicality, comprise upper valve body, seal ring, the bell valve plate of sphere, link assembly, main shaft, driving mechanism, following valve body, connection upper valve body and the flange of following valve body, the pressing plate and the bolt of fixed seal ring, valve inserts the blanking pipeline by inlet flange and outlet(discharge) flange.Seal ring places the bottom surface of inlet, forms sealing pair with valve plate.Valve plate and rod hinge connection, connecting rod is fixedlyed connected with main shaft, and main shaft is connected on the coupling of driving mechanism.The swing of main axis rotation drivening rod, and then the drive valve plate is made arcuate movement, the unlatching of realization valve and closure.In long-term actual the use, find,, still have some shortcomings though this valve can be realized the effective control to the powder blanking, for example:
1, maintenance is inconvenient, and this valve inserts the blanking pipeline by inlet flange and outlet(discharge) flange, when changing seal ring at every turn or handling failsafe valve, all valve must be removed from feeding pipe, and work difficulty is big, and holding time is long;
2, ring wear is fast, has a strong impact on the reliability of valve, and the phenomenon that is not closed completely often appears in valve;
3, seal ring is short working life, changes frequently, has increased maintenance load.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructure, easy to maintenance, long service life, close reliable on-bne repair high-pressure powder-type baiting valve.
The objective of the invention is to realize by following technical proposals.
According to on-bne repair high-pressure powder-type baiting valve of the present invention, comprise upper valve body, seal ring, the bell valve plate of sphere, link assembly, main shaft, driving mechanism, following valve body, connection upper valve body and the flange of following valve body, the pressing plate and the bolt of fixed seal ring, the side that it is characterized in that described upper valve body has a hand hole, and this hand hole is provided with the hand hole sealing cover.
Described seal ring is a polyamide fiber canvas Reinforced Rubber seal ring.
Advantage of the present invention is:
1, owing to have a hand hole in the side of upper valve body, this hand hole is provided with the hand hole sealing cover.Open the hand hole sealing cover during maintenance and get final product handling failure or change seal ring, again the hand hole sealing cover is built again after maintenance is finished.So just realized the original position maintenance of valve on the blanking pipeline, and will not pull down from the blanking pipeline by valve that this has just shortened the repair time greatly.
2, owing to adopted polyamide fiber canvas Reinforced Rubber seal ring, replace original common full rubber material seal ring, mechanical strength and wear-resisting property all are greatly improved, thereby significant prolongation working life, both improve the reliability and the service behaviour of valve, reduced maintenance load again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, on-bne repair high-pressure powder-type baiting valve of the present invention, comprise upper valve body 1, seal ring 3, the bell valve plate 2 of sphere, link assembly 6, main shaft 7, driving mechanism, following valve body 8, connection upper valve body 1 and the flange of following valve body 8, the pressing plate 4 and the bolt 5 of fixed seal ring 3, the side that it is characterized in that described upper valve body 1 has a hand hole 9, and this hand hole 9 is provided with hand hole sealing cover 10.
Described seal ring 3 is a polyamide fiber canvas Reinforced Rubber seal ring.
On-bne repair high-pressure powder-type baiting valve of the present invention can be widely used in industries such as metallurgy, chemical industry, transportation.Can significantly improve Utilization ratio, reduce production costs.
