Abstract
The invention comprises a low-resistance antifouling partition check valve and an external electric control valve pipeline connected between the inlet of the antifouling partition check valve and the control cavity.
Description
[technical field]
The present invention relates to a kind of technical field of valve, particularly relate to and automatically shutting down and check valve with anti fouling partition.
[background technique]
Present mortor operated valve and check valve with anti fouling partition, owing to select independently composite structure such as mortor operated valve and check valve with anti fouling partition for use, its defective is: 1. two valve series connection use that not only sealing effect is poor, leak easily, and flow resistance are big during valve opening; 2. the valve mechanism size is big, and quality is heavy, and inconvenience is installed.
[summary of the invention]
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, with the valve that automatically shuts down and antifouling partition check function is integrated in one.
For achieving the above object, the present invention proposes a kind of automatically shutting down and check valve with anti fouling partition, comprise low resistance check valve with anti fouling partition and external electrically-controlled valve pipeline, it is characterized in that: at the inlet 6 of check valve with anti fouling partition 1 to connecting an electrically-controlled valve pipeline 2 between the control chamber 7.
Described external electrically-controlled valve pipeline comprises solenoid valve, safety check and modulating valve, and solenoid valve 4, safety check 5 and modulating valve 3 are connected in the electrically-controlled valve pipeline.
Described modulating valve is installed in the entry end of solenoid valve.
Prior art of the present invention is compared, entering the mouth of the antifouling isolating valve of lower resistance to being connected to the electrically-controlled valve pipeline between the control chamber, has the function of closing check valve with anti fouling partition automatically, to automatically shut down, antifouling, anti-back flow and automatically function set such as draining be one, it is rational in infrastructure, be skillfully constructed, have promotional value.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1,1 be check valve with anti fouling partition, 2 for the electrically-controlled valve pipeline, 3 for modulating valve, 4 for solenoid valve, 5 for safety check, 6 for inlet, 7 for control chamber.
[specific embodiment]
Referring to Fig. 1, the present invention is made up of low resistance check valve with anti fouling partition 1 and external electrically-controlled valve pipeline 2 two-part; External electrically-controlled valve pipeline 2 is composed in series by solenoid valve 4, safety check 5 and modulating valve 3, is installed on the side of check valve with anti fouling partition 1, is communicated in the inlet 6 and the control chamber 7 of check valve with anti fouling partition 1.
When solenoid valve 4 was opened, medium entered control chamber 7 by inlet 6, solenoid valve 4, safety check 5 and the modulating valve 3 of check valve with anti fouling partition 1.Make inlet/outlet (control chamber communicates with the outlet) pressure of check valve with anti fouling partition 1 consistent, main valve is closed automatically; When solenoid valve 4 cut out, the inlet 6 and the control chamber 7 of check valve with anti fouling partition 1 were cut off, and the pressure of the inlet 6 of check valve with anti fouling partition 1 is greater than the pressure of control chamber 7, and main valve is opened automatically.The pressure of control chamber 7 that cuts off safety check 1 when dirt is during greater than the pressure of inlet 6, and the safety check in the external electrically-controlled valve pipeline can prevent that also medium from flowing backward to inlet 6 from control chamber 7, and main valve is closed automatically.
Claims (3)
1. one kind automatically shuts down and check valve with anti fouling partition, comprises low resistance check valve with anti fouling partition and external electrically-controlled valve pipeline, it is characterized in that: entering the mouth to connecting an electrically-controlled valve pipeline between the control chamber of check valve with anti fouling partition.
2. according to claim 1 automatically shutting down and check valve with anti fouling partition is characterized in that: described external electrically-controlled valve pipeline comprises solenoid valve, safety check and modulating valve, and solenoid valve, safety check and modulating valve are connected in the electrically-controlled valve pipeline.
