Description

A kind of double stub shaft forged steel check valve
Technical field
This utility model belongs to valve field, particularly relates to a kind of double stub shaft forged steel check valve.
Background technology
Valve is the control parts in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief. The opening and closing element of stop valve is the flap of stopper, and sealing is plane or the sea conical surface above, can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium. Due to the valve rod of such valve, to be turned on and off stroke relatively short, and has cutting function very reliably. Therefore, the stop valve valve that dams is highly suitable as cut-out and throttling is used. In existing stop valve in use, the state of its flap is for being all turned on formula or Close All form, it is impossible to achievement unit divides open function, and Flow-rate adjustment is inconvenient.
Summary of the invention
This utility model is for above-mentioned technical problem, it is provided that a kind of convenient double stub shaft forged steel check valve of Flow-rate adjustment.
The technical scheme that this utility model adopts is:
A kind of double stub shaft forged steel check valve, it is characterized in that: include valve body, flap, first valve rod, compact heap, second valve rod, one end of described valve body offers fluid inlet channel and its other end offers fluid outlet channels, described fluid inlet channel, connected entrance is offered between fluid outlet channels, described connected entrance is fixed with the first sealing gasket, described flap is arranged in described fluid outlet channels and its lower end is inserted in the first sealing gasket of described connected entrance, one end towards fluid outlet channels of described flap offers opening, side on described flap offers first flow and its opposite side offers the second runner, described first flow, one end of second runner communicates with opening and its other end communicates with fluid inlet channel, the inside being arranged at described valve body of described first valve rod, the lower end of described first valve rod is connected with flap and its upper end and cylinders, described cylinder is fixed on the outside of described valve body, one end of described compact heap and described opening agree with and it is inserted in described opening, described second valve rod is screw rod, one end of described second valve rod is connected with the other end of described compact heap and its other end passes described valve body and is connected with handle, described second valve rod, the second sealing gasket it is fixed with between valve body.
Described compact heap is fixed with the 3rd sealing gasket towards the side of opening.
Described valve body adopts forged steel to make.
The beneficial effects of the utility model are:
1, this utility model has been offered opening, first flow, the second runner on flap, when flap is in connected entrance, rotating handles, second valve rod drives compact heap to move down, fluid enters fluid outlet channels along first flow, the second runner from fluid inlet channel, it is achieved flap portion is opened, when the first valve rod drives flap to remove from connected entrance, flap is all turned on, and Flow-rate adjustment is convenient;
2, the lifting of the first valve rod is by cylinder control, and automaticity is high;
3, the setting of multiple sealing gaskets, good sealing effect;
4, simple in construction, practicality, it is easy to make;
5, the second valve rod is screw rod, and lift adjustment is simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In figure, 1-valve body, 2-flap, 3-the first valve rod, 4-compact heap, 5-the second valve rod, 6-fluid inlet channel, 7-fluid outlet channels, 8-connected entrance, 9-the first sealing gasket, 10-opening, 11-first flow, 12-the second runner, 13-cylinder, 14-handle, 15-the second sealing gasket, 16-the 3rd sealing gasket.
Embodiment
