Description

A kind of novel balanced type check-valves
Technical field
The utility model belongs to valve technology field more particularly to a kind of novel balanced type check-valves.
Background technique
As situations such as system pipe network develops towards big orifice, high pressure direction, and valve opening torque is big, poorly sealed, is frequent Occur, causes economic loss big, and seriously affected the safety and stability of system.Especially in terms of marine valve, due to Seawater is often mixed into silt, leads to valve blockage or serious wear, it is often necessary to grind to spool, give person works' ring Border causes serious burden.
Summary of the invention
Place, the utility model provide a kind of novel balanced type check-valves in order to overcome the above-mentioned deficiencies of the prior art, should Valve configuration is simple, and compact-sized, circulation is good, safe and reliable.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of novel balanced type check-valves, including valve Body, valve deck, sealing clamp, piston plate, cylinder sleeve, valve rod, the valve deck is inclined to be connected on valve body, and valve is equipped in valve deck Bar is equipped with cylinder sleeve in the valve body at valve deck, piston plate is equipped in cylinder sleeve, and the one side of piston plate is equipped with the groove cooperated with valve rod, Another side is connect with sealing clamp, and the valve body import and exit are equipped with tracting pressuring hole, and the impulse of entrance and exit Hole is connected to by pressure guiding pipe.
In the above-mentioned technical solutions, the pressure guiding pipe is equipped with needle valve.
In the above-mentioned technical solutions, the bottom at the valve body import end is equipped with escape orifice, is equipped with bolt of releasing at escape orifice.
In the above-mentioned technical solutions, sealing ring is equipped at the outer wall of the piston plate upper end.
In the above-mentioned technical solutions, the sealing clamp is connect by fastening screw with piston plate.
In the above-mentioned technical solutions, the valve stem top is connected with handwheel.
The beneficial effects of the utility model are: the balance type check valve structure is simple, flow resistance is low;Pass through the tracting pressuring hole of connection And pressure guiding pipe, make valve import and export pressure balance, torque is small when operating valve lever, and piston plate is made by gravity in the on state With to whereabouts, reach non-return effect;Needle valve makes valve export pressure relatively stable when pressure oscillation is larger;Back out spiral shell of releasing Bolt can be cleared up and be safeguarded to valve by escape orifice, adapt to the requirement of a variety of environment.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
Wherein: 1. valve bodies, 2. sealing clamps, 3. fastening screws, 4. piston plates, 5. cylinder sleeves, 6. sealing rings, 7. valve decks, 8. Handwheel, 9. release bolt, 10. tracting pressuring holes, 11. pressure guiding pipes, 12. needle valves, 13. valve rods.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of novel balanced type check-valves as shown in Figure 1, including valve body 1, valve deck 7, sealing clamp 2, piston plate 4, cylinder 5, valve rod 13 are covered, the valve deck 7 is inclined to be connected on valve body 1, and valve rod 13 is equipped in valve deck 7, the valve body 1 at valve deck 7 It is interior to be equipped with cylinder sleeve 5, be equipped with piston plate 4 in cylinder sleeve 5, the one side of piston plate 4 is equipped with the groove cooperated with valve rod 13, another side with it is close It seals pressing plate 2 to connect, 1 import of valve body and exit are equipped with tracting pressuring hole 10, and the tracting pressuring hole 10 in entrance and exit is logical Cross the connection of pressure guiding pipe 11.1 inlet and outlet tracting pressuring hole of valve body is connected by pressure guiding pipe 11, Compositional balance formula structure.The balance Formula check valve structure is simple, and flow resistance is low;By the tracting pressuring hole 10 and pressure guiding pipe 11 of connection, make valve import and export pressure balance, Torque is small when operating valve lever 13.
Piston plate 4 reaches non-return effect in the on state by gravity to whereabouts.
In the above-mentioned technical solutions, the pressure guiding pipe 11 is equipped with needle valve 12.The adjustable aciculiform in dynamic pressure The aperture of valve 12 has certain buffer function to valve export.
In the above-mentioned technical solutions, the bottom of 1 input end of valve body is equipped with escape orifice, is equipped with bolt of releasing at escape orifice 9.Backing out can release to impurity such as the silts deposited in valve body 1 after releasing bolt 9.
In the above-mentioned technical solutions, sealing ring 6 is equipped at the 4 upper end outer wall of piston plate.Sealing ring 6 make piston plate 4 with Cylinder sleeve 5 forms sealing.
In the above-mentioned technical solutions, the sealing clamp 2 is connect by fastening screw 3 with piston plate 4.
In the above-mentioned technical solutions, the valve stem top is connected with handwheel.The stroke that piston plate 4 is controlled by handwheel 8, from And the opening and closing of control valve.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
