Abstract
The utility model relates to a cut-off and check valve. The bottom end of a screw rod in a valve body is connected with a valve clack body of a cut-off valve and a valve clack of a check valve. One end of the valve clack of a check valve is matched with a valve seat, and the other end of the valve clack of a check valve is glidingly matched with the valve clack body of a cut-off valve. The utility model has double function of the cut-off valve and the check valve, and also has the characteristics of energy saving, good versatility, convenient overhauling, reduction of construction cost, decrease of use amount of valves, realization of long-distance control, etc.
Description
The utility model relates to a kind of valve, and it has stop valve, safety check dual functions.
In the prior art, have to have single stop valve, the safety check with single check function is also arranged by function, but not with the two standard universal valve that combines.
The purpose of this utility model provides a kind of energy-conservation screw down nonreturn valve with stop valve and safety check dual functions.
The purpose of this utility model is achieved in that a kind of screw down nonreturn valve, include valve rod (2), (3), valve gap (5), valve body (6), flap (9), valve seat (10), it is characterized in that leading screw (7) bottom is connected with stop valve valve petal body (8) and safety check flap (9) in valve body (6), safety check flap (9) one ends match with valve seat (10), and the other end and stop valve valve petal body (8) are slidingly matched.
Compare with prior art, the utility model unites two into one stop valve and two kinds of structures of safety check, on a kind of product, finished simultaneously and ended and two kinds of functions of non-return, this valve size adopts the length dimension standard of gate valve simultaneously, can replace two valves by a valve, dark bar in it adopts in addition, interior loop bar structure, height and external form are less applied widely, alternative one-way valve, safety check, stop valve, long apart from control valve, Y type Angle Stop valves etc., it has energy-conservation, reduce the valve usage quantity, reduce engineering cost, versatility is good, maintenance and inspection are advantage easily, and this valve also can have the automatic drainage function, the pressure limit function, safety anti-explosive splits function.
Be described in detail technical solution of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of screw down nonreturn valve.
As Fig. 1, a kind of screw down nonreturn valve includes valve rod 2,3, valve gap 5, valve body 6, flap 9, valve seat 10, and leading screw 7 bottoms are connected with stop valve valve petal body 8 and safety check flap 9 in valve body 6, safety check flap 9 one ends match with valve seat 10, and the other end and stop valve valve petal body 8 are slidingly matched.This product comprises that also drain valve 11 is located on the entrance channel, and pressure governor 4 is located on the valve gap 5.
Open handwheel, handwheel drives upper and lower valve rod 2,3 actions, valve rod drives leading screw 7 and rises, leading screw 7 drives stop valve valve petal body 8 and promotes, valve opening, the safety check flap is in free state, and fluid flows into promotion safety check flap 9 from inlet and moves up, and safety check flap 9 relative valve seats 10 upwardly open; Fashionable from the Way out reverse flow when fluid, the safety check flap is closed at once, moves down and valve seat 10 closures.The effect of pressure governor 4 is when superpressure, voltage regulator operation.The effect of drain valve 11 is: during valve opening, when fluid flowed into from import, automatic drainage valve 11 pressurizeds were closed, and fashionable from reverse flow when fluid, safety check flap 9 does work with valve seat 10, and the automatic drainage valve does not have pressure, opens automatically to sluice.
Claims (2)
1, a kind of screw down nonreturn valve, include valve rod (2), (3), valve gap (5), valve body (6), flap (9), valve seat (10), it is characterized in that leading screw (7) bottom is connected with stop valve valve petal body (8) and safety check flap (9) in valve body (6), safety check flap (9) one ends match with valve seat (10), and the other end and stop valve valve petal body (8) are slidingly matched.
2, screw down nonreturn valve according to claim 1 is characterized in that it comprises that also drain valve (11) is located on the entrance channel, and pressure governor (4) is located on the valve gap (5).
