Abstract
The utility model discloses a novel reversing valve, which is mainly formed by a valve body, a valve rod, a bearing, a bearing sealing gasket and an oil injection hole. The reversing valve is characterized in that a sealing disk is additionally arranged on the upper side of the bearing at the bottom of the valve, and the upper surface of the sealing disk is in a cellular shape. A lubricating pipeline and a screwing oil injection cup are arranged at the bottom of a bearing cover. The novel reversing valve can be lubricated conveniently and timely, impurities can not enter the inside of the bearing, service life is greatly prolonged, device failure rate of a device is reduced, and continuity of workshop production is improved.
Description
Technical field
The utility model relates to the foundry equipment field, particularly a kind of novel selector valve.
Background technique
At present; Selector valve is to be used for the flow direction of coal gas and air is changed, and is mixed with some impurity in air and the coal gas, and these impurity can accumulate in the selector valve bottom; Because the O RunddichtringO is only arranged one at selector valve bottom bearing top; Be very easy to wearing and tearing, it is inner to cause a large amount of impurity to get into bearing, makes bearing stuck.In addition, the bottom bearing oil hole is in the bearing cap bottom, because lower space is very narrow, can't carry out oilyly at ordinary times, causes the bearing oil starvation to damage.After the damage of bearings, need disassemble, could change bearing, expend very big man-hour, can influence production again simultaneously valve.
Summary of the invention
The utility model has overcome that existing selector valve bottom bearing upside is poorly sealed, the bottom bearing oil hole refuels inconvenience, flimsy deficiency, and the utility model provides a kind of novel selector valve tight, that effectively stop impurity to invade, increase the service life greatly that seals.
The utility model is that the technological scheme that its technical problem of solution is adopted is: a kind of novel selector valve; Mainly constitute by valve body, valve rod, bearing, bearing seal pad, oil hole; It is characterized in that installing a seal disc additional at the upside of its valve bottom bearing, the seal disc upper surface is cellular.In the bearing cap bottom lubricating pipe is installed, and a cap-rotating type priming cup is installed.
The beneficial effect of the utility model is: bearing lubrication is convenient, timely, and impurity can't get into bearing inside, increases the service life greatly, reduces equipment failure rate, has improved the continuity of Workshop Production.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Figure is the structural representation of the utility model.
Valve rod in the drawings, 1, seal disc, 2, bearing, 3, bearing cap, 4, lubricant pipe, 5, lubricating cup, 6, valve body, 7.
Embodiment
