Abstract
The utility model relates to an ash-resistant hydraulic controlling open or close valve, which is arranged on a hot water circulating pipeline for using to prevent the water hammer phenomenon and to improve the impurities filtering capacity in water. The utility model is composed of a liquid controlling port, a valve cover, a piston, a spring, a valve rod, a valve clack, a valve seat sleeve, a filter screen, a valve body, a water flow inlet, a water outlet pipe, a safety valve body, a valve element spring, a regulating screw, a safety valve water inlet, a safety valve water outlet, etc. The utility model is characterized in that the safety valve water inlet is arranged below the valve clack and is connected with a casing body, the safety valve water outlet is connected with the water outlet pipe, and the filter screen is arranged at one side of the water flow inlet and is connected with the casing body. The utility model has the advantages of notable practical utilization and being suitable for controlling the return water pipe of a hot-water circulating system.
Description
The utility model relates to the anti-water attack fluid-control starting and stopping valve on a kind of hot water cyclesystem pipeline.
Known to the author, be installed in the fluid-control starting and stopping valve on the hot water cyclesystem pipeline at present, closing often because of swiftly flowing current by suddenly, cause taking place strong sound equipment and vibration by producing water hammer.Its internal screen area is little in addition, and as shown in Figure 2, filter screen (2) is located at flap (3) below and is connected with valve body (1).This mode filter area is little, and the sewage space is big, and the water purification space is little, easily stopped up by foreign material, and the normal operation of influence.
The purpose of this utility model is exactly the anti-water attack fluid-control starting and stopping valve that the anti-water attack of a kind of energy will be provided and strengthen filtering effect.
A kind of anti-water attack fluid-control starting and stopping valve is made up of hydraulic control mouth, valve gap, piston, spring, valve seat cover, valve rod, flap, valve opening, isolating plate, filter screen, housing, plug, flow inlet, water export, outlet pipe, safety valve valve body, spool, valve core spring, adjustment screw, safety valve water intake, safety valve water outlet, it is characterized in that the safety valve water intake is connected with valve body below flap, the safety valve water outlet is connected with outlet pipe, filter screen is located at flow inlet one side, its upper end is connected with case top, and the lower end is connected with housing bottom.
The purpose of this utility model is to realize like this, as shown in Figure 1, after the liquid of certain pressure is imported by hydraulic control mouth (1), piston (2) overcomes spring (3) under the effect of hydraulic coupling elastic force moves downward, and flap (9) is opened valve opening (19) by valve rod (7), conducting between this moment flow inlet (5) and the water export (17).
When the pressured fluid of locating when hydraulic control mouth (1) disappears, piston (2) moves upward under the elastic force of spring (3), and flap (9) is closed valve opening (19) rapidly by valve rod (7), current below flap this moment (9) are under the effect of inertial force, pressure moment increases, meanwhile, spool (12) in the safety valve valve body (14) is under the impact of high-pressure water flow, the elastic force that overcomes valve core spring (13) is opened safety valve water intake (11), and the inner chamber of high-pressure water flow by safety valve valve body (14) entered by safety valve water outlet (16) that outlet pipe (18) is interior to be mixed with low-pressure water.After high-pressure water flow was released, spool (12) resetted rapidly under the elastic force of valve core spring (13), safety valve water intake (11) is closed, and make the fluid-control starting and stopping valve be in normal closed condition, thereby eliminated water hammer.
Adjust the elastic force that screw (15) is used to adjust valve core spring (13).
Filter screen (8) is located at flow inlet (5) one sides, and for increasing filter area and effectively impurity being swept away from filter screen top, filter screen (8) is vertical oblique layout, and directly facing to flow inlet (5).
The plug (10) of outwarding winding can carry out blowdown.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing 1 is anti-water attack fluid-control starting and stopping valve arrangement generalized section.
Accompanying drawing 2 is existing fluid-control starting and stopping valve arrangement generalized section.
As shown in Figure 1, valve gap (21) is connected with the top of valve body (20).Pressing valve seat cover (4) below the valve gap (21), valve seat cover (4) lower end and isolating plate (6) are connected.Piston (2) has spring (3) below the piston (2) in the chamber of valve gap (21), spring (3) lower end withstands on the intermediate clapboard of valve seat cover (4).The upper end of valve rod (7) is connected with piston (2), and the lower end is connected with flap (9).
Safety valve water intake (11) on the safety valve valve body (14) is connected with housing (20) in flap (9) below, safety valve water outlet (16) is connected with outlet pipe (18), valve core spring (13) one ends withstand on the spool (12), and the other end withstands on the slide block of adjusting screw (15).
Contrast accompanying drawing (2) filter screen (8) is located at flow inlet (5) one sides, and the upper end of filter screen (8) is connected with the top of housing (20), and the lower end is connected with the bottom of housing (20).Plug (10) is connected with the cavity bottom surface of housing (20) bottom.
On probation show that the utility model prevent water attack fluid-control starting and stopping valve, anti-water attack is effective, and filter capacity is strong, is difficult for stopping up, and opens and closes reliably.
Claims (2)
1, a kind of anti-water attack fluid-control starting and stopping valve, by hydraulic control mouth (1), valve gap (21), piston (2), spring (3), valve seat cover (4), valve rod (7), flap (9), isolating plate (6), filter screen (8), housing (20), plug (10), flow inlet (5), outlet pipe (18), safety valve valve body (14), spool (12), valve core spring (13), adjust screw (15), safety valve water intake (11), safety valve water outlet (16) is formed, it is characterized in that, safety valve water intake (11) is connected with valve body (20) in flap (9) below, and safety valve water outlet (16) is connected with outlet pipe (18).
