Abstract
The utility model relates to a multifunctional electric hydraulic valve used for industries such as petroleum, chemical engineering, etc. The multifunctional electric hydraulic valve is connected with corresponding controllers in order to automatically control conveying media. The multifunctional electric hydraulic valve is characterized in that a valve core guide rod is provided with a diaphragm, and the diaphragm between an O-shaped ring and a gasket is positioned on a leather bowl washer. The utility model has simple structure and control circuit, easy fabrication, easy installation, convenient maintenance, opening and closing the valve via multiple stages, fundamentally water impact removal, low opening pressure, reliability for opening and closing the valve via the negative pressure of media and spring force, constant current via connecting with the controllers and high conveying accuracy.
Description
A kind of multifunctional electrohydraulic valve is used for industries such as oil, chemical industry and is connected with corresponding controller, realizes the automatic control to fed sheet of a media.
Before the utility model was made, in prior art, common electro hydraulic valve was mainly by the valve body part, control system, and pipeline connecting device is formed.Valve gap and valve base chamber arming diaphragm in this valve body part, in control system, spring is installed in outside the seal, the control valve of this structure generally only is an on-off action, and there is serious water attack in pipeline, and is fragile, and use and keep in repair inconvenience, the cracking pressure height, the fed sheet of a media instability of flow, it is low to cause control automatically to send precision.
It is a kind of simple in structure that the purpose of this utility model is to provide, and makes.Easy to use, can multistage open and close valve, eliminate water attack, cracking pressure is low, applied range, and can improve the transmission precision of fed sheet of a media.
The utility model is mainly by the valve body part, control system, and pipeline connecting device is formed.Screw by bolt (5), nut (6) by valve seat (3), valve gap (1) and spool and to form the valve body part, spool comprises O type circle (28), (31), (33), packing ring (30), gag (32), chock (34), bowl pad (39), pad (40) is by nut (37), spring washer (38) guide rod (36) of packing into, at O type circle (28), between the bowl pad (39) diaphragm (29) is housed, diaphragm (29) edge is fixed on valve seat (3), and between the valve gap (1).Control system is by normally open solenoid valve (15), and terminal box (16), normally closed solenoid valve (27) are formed.Normally open solenoid valve in the control system (15), sealing plug (53), spring (54) seal (56) of packing into, seal (56), spring (43), O type circle (44) nut (46) of packing into screws in valve body (42).

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model is mainly by the valve body part, control system, and pipeline connecting device is formed.
The valve body part.As Fig. 1, shown in Figure 3.Screw and form valve body by bolt (5), nut (6) by valve seat (3), valve gap (1) and spool.Axle sleeve (35) valve gap (1) of packing into.Sealing seat (41) valve seat (3) of packing into.Spool is by O type circle (28), (31), (33), diaphragm (29), packing ring (30), gag (32), chock (34), bowl pad (39), pad (40), by nut (37), spring washer (38) guide rod (36) composition of packing into.Diaphragm (29) is installed between the bowl pad (39), and diaphragm (29) edge is fixed between valve seat (3) and the valve gap (1).Control system.As Fig. 2, Fig. 4, shown in Figure 5, by normally open solenoid valve (15), terminal box (16), normally closed solenoid valve (27) is formed control section.Nut (14) connection is often opened, normally closed solenoid valve.
Sealing plug (53) spring (54) seal (56) of packing into.Seal (56), spring (43), O type circle (44) nut (46) of packing into screws in valve body (42).Static iron core (59), moving iron core (60) retaining core pipe (63) of packing into reinstalls iron core base (47).Iron core base (47), O type circle (45), (57), cassette holder (48) screw in nut (46).Earth tag (58) is inserted in retaining core pipe (63).Cut magnet ring (50) line bag (49) the cover lambda line ladle cover (52) of packing into and be inserted in retaining core pipe (63) again.Putting into spring washer (51) in the lid (61) is spun on the cassette holder (48) again.Form normally open solenoid valve (15) like this, screw (55) is a set screw.Label (62) glue is on lid (61).
Static iron core (67) retaining core pipe (63) of packing into reinstalls iron core base (47).Sealing plug (53), spring (66) the moving iron core (64) of packing into reinstalls retaining core pipe (68).Iron core base (47) cassette holder (48) of packing into reinstalls O type circle (44) and screws in valve body (42).Earth tag (58) is inserted in retaining core pipe (63).Cutting magnet ring (50) line bag (49) the cover lambda line ladle cover (52) of packing into is inserted in and puts into spring washer (51) in retaining core pipe (68) lid (61) and be spun on the cassette holder (48) again.Form normally closed solenoid valve (27) like this.Screw (65) is a set screw.Label (69) glue is on lid (61).Pipeline connecting device.As shown in Figure 1 and Figure 2.By pipe (2), connect cover (4), pipe (7), plug screw (8), pipe (9), carriage (10), band filter connector (11), ball valve (12), union elbow (13), nut (14), pipe (17), joint (18), tee union (19), pipe (20), connect cover (21), nut (22), pad (23), spring washer (24), free flow coupling (25), connect mother (26) composition pipeline and attachment portion.Carriage (10) partly is connected one by bolt (5), nut (6) with valve body.
Compared with the prior art the utility model has the following advantages: 1, structure, control are returned The road is simple, manufacturing, installation, maintenance are convenient; 2, multistage open and close valve, fundamentally Eliminate water attack; 3, opening pressure is low, applied range; 4, valve utilizes medium negative pressure With the spring force closure, close reliably, raise life length; 5, do not have outside packing seal, leakage can The energy property is little; But 6, be connected constant current with controller, improved the transmission precision.
