Abstract
A combined hydraulic control switch valve fixed on the hot water circulating pipe can prevent the water hammer phenomena; the utility model comprises a liquid control port, a valve cover, a cylinder liner, a piston, a spring, a valve rod, a valve clack, a valve seat sleeve, a pressure regulating plate, a shell body, a water inlet, an outlet pipe, a safety valve body, a valve core, a valve core spring, a regulating screw, a safety valve water inlet, a safety valve water outlet; the utility model is characterized in that the safety valve water inlet is connected with the shell body under the valve clack, the safety valve water outlet is connected with the outlet pipe, the pressure regulating plate is connected with the shell body on one side of the water flow. The utilizing effect of the utility model is remarkable; the utility model is applicable to backwater control of a hot water circulating system.
Description
The utility model relates to the combined type fluid-control starting and stopping valve on a kind of hot water circuit 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.
The purpose of this utility model is exactly the combined type fluid-control starting and stopping valve that the anti-water attack of a kind of energy will be provided.
A kind of combined type fluid-control starting and stopping valve is made up of hydraulic control mouth, valve gap, cylinder sleeve, piston, spring, valve seat cover, valve rod, flap, valve opening, isolating plate, regulator board, 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, regulator board 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 drawings, 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), high-pressure water flow passes through the inner chamber of safety valve valve body (14), is entered in the outlet pipe (18) by safety valve water outlet (16) and mixes 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).
Regulator board (8) is located at flow inlet (5) one sides, and regulator board (8) is gone up the uniform regulator hole (23) that is drilled with, and when current pass through regulator hole (23), can make water flow pressure obtain slow unraveling silk.Regulator board (8) is vertical oblique layout, and directly facing to flow inlet (5), in pressure regulation, also can impurity big in the current be filtered, and it is swept away rapidly from regulator board top.
The plug (10) of outwarding winding can carry out blowdown.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a combined type fluid-control starting and stopping valve arrangement section diagrammatic sketch.
As shown in drawings, valve gap (22) is connected with the top of valve body (20).Cylinder sleeve (21) is arranged below the valve gap (22), pressing valve seat cover (4) below the cylinder sleeve (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 cylinder sleeve (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).
Regulator board (8) is located at flow inlet (5) one sides, and the upper end of regulator board (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 showing, the utility model combined type fluid-control starting and stopping valve, anti-water attack is effective, opens and closes reliable.
Claims (2)
