Preferably, described main control water route comprises the import main isolating valve, the main filter being connected with import main isolating valve that are connected with import, the outlet main isolating valve that is positioned at the main pilot valve in main filter downstream, is connected and is connected with outlet with main pilot valve.
Preferably, described time control water route comprise the import time separating valve, inferior filter, the inferior pilot valve being connected with inferior filter that are connected with import time separating valve that are connected with import, be connected with inferior pilot valve and with export the inferior separating valve of the outlet being connected.
Preferably, described valve inner is provided with the hyperbaric chamber that is connected with import, the low-pressure cavity being connected with outlet, is positioned at the main valve chamber of low-pressure cavity top and is positioned at the inferior valve chamber of main valve chamber top.
Preferably, it further comprises the primary and secondary barrier film being set on valve rod and is set in the spring on valve rod and between primary and secondary barrier film, and wherein main barrier film is positioned at main valve chamber, and inferior barrier film is positioned at time valve chamber.
Preferably, described main control water route further comprises the flow stabilizer being all connected with main pilot valve with main valve chamber, and inferior pilot valve in inferior control water route is connected with time valve chamber.
The utility model advantage is: guarantee the stable and functional reliability of downstream pressure, overpressure protection after valve is provided, reduce unnecessary system-down and safeguard.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Embodiment
Embodiment: as shown in Figure 1, it is the specific embodiment of a kind of safety type reduction valve in the utility model, and it comprises: valve body 10, be arranged on valve gap 12 on valve body 10, be arranged on valve rod 14 between valve body 10 and valve gap 12, be set in the primary and secondary barrier film 16,17 on valve rod 14 and be set in spring 18 on valve rod 14 and between primary and secondary barrier film 16,17, through valve body 10 and there is import 22 the and honeycomb duct 20 of the outlet 24 and primary and secondarys that are connected with outlet 24 with import 22 is controlled water routes.Valve body 10 inside are provided with the hyperbaric chamber 100 that is connected with import 22, with outlet 24 low-pressure cavity that are connected 102, be positioned at the main valve chamber 103 of low-pressure cavity 102 tops and be positioned at the inferior valve chamber 104 of main valve chamber 103 tops.Main barrier film 16 is positioned at main valve chamber 103, and inferior barrier film 17 is positioned at time valve chamber 104.
Main control water route comprises import main isolating valve, the main filter 40 being connected with import main isolating valve being connected with import 22, the main pilot valve 50 that is positioned at main filter 40 downstreams, be connected with main pilot valve 50 and with the outlet 24 outlet main isolating valves that are connected and the flow stabilizer 60 that is all connected with main pilot valve 50 with main valve chamber 103.Wherein import main isolating valve and outlet main isolating valve are referred to as main isolating valve 30.
Inferior control water route comprises the import that is connected with import 22 time separating valve, inferior filter 42, the inferior pilot valve 52 being connected with inferior filter 42 that are connected with import time separating valve, be connected with inferior pilot valve 52 and with export the inferior separating valve of 24 outlets that are connected.Wherein time pilot valve 52 is connected with time valve chamber 104.Import time separating valve and outlet time separating valve are referred to as time separating valve 32.
The control that main pilot valve 50 keeps downstream pressure, under water flow condition, 50 pairs of small variations of pressure of main pilot valve are made a response, and by regulating pressure more than main barrier film in lower control chamber to come the position of control valve, the pressure in downstream is basicly stable to be remained on the point that main control water route sets.When main pilot valve 50 is malfunctioning, inferior pilot valve 52 work, conventionally the pressure that time pilot valve 52 is set is higher than the pressure of main pilot valve 50, in inferior valve chamber 104, inferior barrier film 17 is carried out to active Standby control, realize thus the control that time pilot valve 52 keeps downstream pressure, if downstream pressure raises fast, rapid reaction can be made in inferior control water route, and the inferior barrier film 17 in inferior valve chamber 104 is exerted pressure.So no matter what kind of fluctuation occurs for the fluid of upstream or pressure, it can keep the constant of downstream pressure, thereby eliminate the possibility because of main control water route and main diaphragm failure generation downstream superpressure.
The utility model is controlled water route by primary and secondary two-stage and is formed, if main barrier film, main pilot valve or main filter are malfunctioning or break down, time control water route and can allow valve that unremitting stress management is provided, and carries out active Standby control.Time barrier film is always outside honeycomb duct, so the possibility that dust or chip cause inferior control water route to go wrong is little in addition.By two valve chambers and two cover pilot systems, as a whole set of unit, working thus, is the ultimate guarantee that prevents from occurring because of malfunctioning or fault all troubles.
Certainly above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
