Description
Technical field
The invention belongs to valve field, more particularly to a kind of pneumatic forged steel check valve.
Background technology
Valve is the control unit in fluid delivery system, with cut-off, regulation, 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 in plane or the extra large conical surface, can be used to control the flowing of all kinds fluids such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium above.Due to the valve rod of such valve, to be turned on and off stroke relatively short, and with very reliable cutting function.Therefore, the stop valve valve that dams is highly suitable as use of cutting off and throttle.In existing stop valve in use, the state of its flap is to be all turned on formula or Close All form, it is impossible to which achievement unit point open function, Flow-rate adjustment is inconvenient.
The content of the invention
The present invention is directed to above-mentioned technical problem, there is provided a kind of convenient pneumatic forged steel check valve of Flow-rate adjustment.
The technical solution adopted in the present invention is：
A kind of pneumatic forged steel check valve, it is characterised in that：Including valve body,Flap,First valve rod,Compact heap,Second valve rod,One end of the valve body offers fluid inlet channel and its other end offers fluid outlet channels,The fluid inlet channel,Connected entrance is offered between fluid outlet channels,The first sealing gasket is fixed with the connected entrance,The flap is located in the fluid outlet channels and its lower end is inserted in the first sealing gasket of the connected entrance,One end towards fluid outlet channels of the flap offers opening,Side on the flap offers first flow and its opposite side offers second flow channel,The first flow,One end of second flow channel is communicated with opening and its other end is communicated with fluid inlet channel,The inside for being arranged at the valve body of first valve rod,The lower end of first valve rod is connected and its upper end and cylinders with flap,The cylinder is fixed on the outside of the valve body,One end of the compact heap is agreed with the opening and it is inserted in the opening,Second valve rod is screw rod,One end of second valve rod is connected with the other end of the compact heap and its other end passes the valve body and is connected with handle,Second valve rod,The second sealing gasket is fixed between valve body.
The compact heap is fixed with the 3rd sealing gasket towards the side of opening.
The valve body is made using forged steel.
Beneficial effects of the present invention are：
1st, opening, first flow, second flow channel have been opened up on flap in the present invention, when flap is in connected entrance, rotating handles, second valve rod drives compact heap to move down, fluid enters in fluid outlet channels along first flow, second flow channel from fluid inlet channel, realizes that flap portion is opened, when the first valve rod drives flap to be removed from connected entrance, flap is all turned on, and Flow-rate adjustment is convenient；
2nd, the lifting of the first valve rod is by cylinder control, high degree of automation；
3rd, the setting of multiple sealing gaskets, good sealing effect；
4th, simple structure, practicality, it is easy to make；
5th, the second valve rod is screw rod, and lift adjustment is simple.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
In figure, 1- valve bodies, 2- flaps, the valve rods of 3- first, 4- compact heaps, the valve rods of 5- second, 6- fluid inlet channels, 7- fluid outlet channels, 8- connected entrances, the sealing gaskets of 9- first, 10- openings, 11- first flows, 12- second flow channels, 13- cylinders, 14- handles, the sealing gaskets of 15- second, the sealing gaskets of 16- the 3rd.
