Abstract
The utility model provides a triple valves that dam, includes the valve body, the right -hand member of valve body is the water inlet, the left end of valve body is the delivery port, the water inlet is the same with the radius of delivery port cross section, the mid -mounting of valve body has the case, the case upper end is equipped with the telescopic link, the telescopic link activity is pegged graft in the fixed column, at the fixed handle that is equipped with in valve body outside fixed column upper end, the case lower extreme is equipped with two connecting rods, a choked flow body is connected respectively to the other end of connecting rod, hinder the fluidic cross section for circular, the radius of choked flow body cross section is the same with the cross section radius of water inlet internal surface, it is rubber to hinder the fluidic material. The utility model provides a triple valves that dam, case and two choked flow bodies carry on triple damming water inlet and delivery port, have improved the leakproofness greatly, have stopped the emergence of revealing the accident, guarantee the normal work of pipeline.
Description
Technical field
The utility model belongs to valve preparation field, particularly relates to a kind of triple valve that dams.
Background technique
For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium, play the effect of damming with water conservancy diversion, existing valve mechanism is simple, river closure mode is single, gap between Long-Time Service back valve core and valve body is increasing, sealability reduces, and causes the leakage of liquid in pipe body.
Summary of the invention
In view of this, the utility model object is to provide a kind of triple valve that dams, and makes valve energy convection cell farthest carry out choked flow.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of triple valve that dams, comprise valve body, the right-hand member of described valve body is water intake, the left end of described valve body is water outlet, described water intake is identical with the radius of water outlet cross section, the middle part of described valve body is provided with spool, described spool upper end is provided with flexible rod, described flexible rod activity is plugged in fixing column, outside valve body, fixing column upper end is fixed with handle, described spool lower end is provided with two connecting rods, the other end of described connecting rod connects a bluff body respectively.
Further, the cross section of described bluff body is circular, and the radius of described bluff body cross section is identical with the cross sectional radius of water intake internal surface, and the material of described bluff body is rubber.
Further, described spool is cross section is circular spheroid, and described spool is crossed win and is plugged in valve body, and the radius of described water intake internal surface cross section is less than the radius of spool cross section.
Further, described valve body is positioned at the groove being provided with fixed spool bottom spool.
Owing to have employed technique scheme, the beneficial effects of the utility model are: triple valves that dam that the utility model provides, spool is positioned at the middle part of valve body, when downward promotion flexible rod, spool can move downward and prop up groove, now water intake and water outlet block by spool, spool connects two bluff bodys by connecting rod, bluff body can block water intake and water outlet respectively along with spool moves downward, spool and bluff body carry out triple damming to water intake and water outlet, substantially increase sealing, stop the generation of leakage accident, ensure the normal work of pipeline.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of triple valve that dams, comprise valve body 1, the right-hand member of described valve body 1 is water intake 2, the left end of described valve body 1 is water outlet 3, described water intake 2 is identical with the radius of water outlet 3 cross section, the middle part of described valve body 1 is provided with spool 4, described spool 4 upper end is provided with flexible rod 5, the activity of described flexible rod 5 is plugged in fixing column 6, outside valve body 1, fixing column 6 upper end is fixed with handle 7, described spool 4 lower end is provided with two connecting rods 8, the other end of described connecting rod 8 connects a bluff body 9 respectively, the cross section of described bluff body 9 is circular, the radius of described bluff body 9 cross section is identical with the cross sectional radius of water intake 2 internal surface, the material of described bluff body 9 is rubber, described spool 4 for cross section be circular spheroid, described spool 4 is crossed win and is plugged in valve body 1, the radius of described water intake 2 internal surface cross section is less than the radius of spool 4 cross section, described valve body 1 is positioned at the groove 10 being provided with fixed spool bottom spool 4.When valve is released, spool 4 and bluff body 9 are all positioned at above water intake 2 and water outlet 3, when needs carry out choked flow, downward pressing handle 7, now under the drive of handle 7, flexible rod 5 can move downward, now spool 4 also can move downward thereupon, spool 4 can drive bluff body 9 to move downward while moving downward, when bluff body 9 touches the diapire of valve body 1, under the traction of connecting rod, can move respectively to water intake direction and water outlet direction, spool 4 is crossed win and is plugged in the middle part of valve body 1, and the radius of spool 4 is greater than the radius of water intake 2, when spool 4 props up groove 10, water intake 2 and water outlet 3 can block by spool 4, due to bluff body 9 for cross section is circular spheroid, and the radius of bluff body 9 is identical with the radius of water outlet 3 with water intake 2, water intake 2 and water outlet 3 are closed by two bluff bodys 9 respectively, under the collocation of spool 4 and two bluff bodys 9, carried out to water intake 2 and water outlet 3 triple damming, substantially increase sealing, stop the generation of leakage accident, ensure the normal work of pipeline.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the application.
