Abstract
The utility model belongs to a check valve which is applicable to steam boilers for civil and military use as well as assistant water supply equipment systems of the boilers, in particular to a flange connecting ball check valve. The flange connecting ball check valve comprises a flange (1), an outlet valve seat (2), a valve body (3), a check plug (4), a spring (5), a valve ball (6) and a valve seat (7). The flange connecting ball check valve has simple manufacture, good sealing performance, safety and reliability, convenient maintenances and long serving life.
Description
The utility model belongs to safety check, is applicable to industry, civilian steam water boiler and boiler auxiliary feedwater device systems, and particularly a kind of flange connects ball check valve.
Present check valve seal is not tight, and is easy to wear, and easily sticking card easily causes medium refluence phenomenon, and working life is short.
Goal of the invention of the present utility model is to provide a kind of flange to connect ball check valve according to the problems referred to above, this flange connects ball check valve, inlet valve seat (7) is taper, there is between spring (5), valve ball (6) and the valve pocket space big in the valve pocket, can solve poorly sealed, easy to wear, easily sticking card easily causes problems such as medium refluence phenomenon and working life weak point.
Accompanying drawing is that flange connects the ball check valve cut-away view.
The utility model is to realize like this (such as figure): a kind of flange connecting ball check valves is by flange (1), outlet valve seat (2), valve body (3), check plug (4), spring (5), valve ball (6) and Entrance valve seat (7) forms, and spring (5) is arranged, inlet valve between outlet valve seat (2) and the valve ball (6) Seat (7) is integrated with valve body (3), and entrance valve seat (7) is taper.
The utility model processing is simple, safe and reliable, and good seal performance is easy to maintenance, long service life.
Below in conjunction with accompanying drawing an embodiment is described: at first make mould, behind the casting, with after the machined into spring (5) being fixed on the outlet valve seat (2) by the figure requirement, the valve pocket of again valve ball (6) being packed into, outlet valve seat (2) is gone up on valve body (3), and assembling is finished, and pressure testing detects.
Claims (1)
1. a flange connection ball check valve is made up of flange (1), outlet valve seat (2), valve body (3), inspection plug (4), spring (5), valve ball (6) and inlet valve seat (7), it is characterized in that exporting between valve seat (2) and the valve ball (6) spring (5) is arranged, inlet valve seat (7) is an one with valve body (3), and inlet valve seat (7) is taper.
