Description
Technical field
The utility model relates to a kind of fire-fighting equipment, is specifically related to a kind of fire main and controls selector valve.
Background technique
Fire main in the market controls selector valve and generally all there is inconvenient operation, the problem such as sealing is not good, easily leak, when the on-the-spot fireman that puts out a fire operates and controls selector valve, not only rotate inconvenience, and joint has water and oozes out or spill, affect the conveying of water, thus affect fire fighting progress, and then cause great personnel and economic loss.If the situation of leaking often occurs, easily make control selector valve get rusty, working life shortens.
Summary of the invention
Control the problems such as selector valve operation is inconvenient, sealability is not good for fire main in prior art, invented a kind of fire main simple to operate, good seal performance and controlled selector valve.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs:
A kind of fire main controls selector valve, and comprise valve body, valve seat, valve rod and spool, its main points are, described valve body is connected with valve seat by screw thread, are provided with seal ring in one end of threaded connection place; Described valve rod is through valve seat, and one end is upwards exposed and is provided with handwheel, and the other end is arranged in valve body and is connected with spool; Spool is provided with sealing gasket, and described sealing gasket is fixed on spool side by nut; Described valve seat top is provided with groove, is provided with nylon pad in groove, and described nylon pad is fixed by nut.
As preferably, the described top being positioned at the valve rod of handwheel is fixed on handwheel by nut, is provided with pad between described nut and valve rod.
As preferably, between described sealing gasket and nut, copper backing is installed.
As preferably, described nut is hexagonal block.
The beneficial effects of the utility model: in valve body, multiple joint is all provided with sealing gasket, make sealability better, antileaking, even if after using long-time, sealability still can ensure, therefore long service life, and it is easy to operate, user-friendly that this fire main controls selector valve.
