Abstract
The utility model relates to a hydraulic membrane two-way valve which is characterized by comprising a valve body provided with an inner cavity, a valve cover and a membrane. The valve cover is arranged on the valve body. The valve cover is provided with a control opening. The membrane is arranged between the valve body and the valve cover. A spring is arranged between the valve cover and the membrane in an abutting mode. A water inlet and a water outlet are respectively arranged at two ends of the valve body. A sealing tape is arranged in the inner cavity of the valve body and located between the water inlet and the water outlet. When the hydraulic membrane two-way valve is in a turn-off state, under the action of a pressure liquid source of the control opening and the elastic force of the spring, the membrane abuts against the sealing tape, and at the moment the communication between the water inlet and the water outlet is shut off. The hydraulic membrane two-way valve is simple and compact in structure, and low in manufacturing cost. Moreover, pressure liquid is utilized to control the membrane to open or close a flow channel, actions of opening and closing are rapid and accurate, and consequently control power is small, and usage cost is low, and the failure rate is reduced.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of barrier film Twoway valves that surges.
Background technique
At present, that the valve of supporting water intake for water-treating equipment such as self-cleaning filter, common husky filters, water outlet and sewage draining exit control flow direction adopts usually is electronic, Pneumatic butterfly valve or ball valve, butterfly valve, ball valve comprise respectively the parts such as sealing gasket, directed seat, valve block, complex structure, manufacture cost is high, and rate of fault is high; Simultaneously, the power ratio control of electronic, Pneumatic butterfly valve or ball valve is large, and user cost is higher; The blanking time of control opening and closing is long, can't finish fast the opening and closing action, is difficult to accurately control water intake, water outlet and sewage draining exit opening and closing.
The model utility content
The applicant is studied improvement for above-mentioned problem, and a kind of barrier film Twoway valves that surges is provided, and is simple and compact for structure, low cost of manufacture, and power ratio control is little, and opening and closing are moved quick and precisely, reduce trouble, user cost is low.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of barrier film Twoway valves that surges comprises the valve body, valve gap and the barrier film that are provided with inner chamber, and described valve gap is installed on the described valve body, and described valve gap is provided with the control mouth, and described barrier film is installed between described valve body and the valve gap, and spring supports and is contained between described valve gap and the barrier film; The two ends of described valve body are provided with water intake and water outlet, are provided with sealing strip in the described body cavity between described water intake and the described water outlet; In the time of in off position, under the pressure liquid source and the elastic force effect of described spring of control mouthful, described barrier film is against on the described sealing strip, closes being communicated with between described water intake and the described water outlet.
Further:
Described water intake and water outlet are provided with flange plate.
Technique effect of the present utility model is:
The disclosed a kind of barrier film Twoway valves that surges of the utility model, simple and compact for structure, low cost of manufacture is utilized pressured fluid control barrier film unlatching or is closed flow channel, and opening and closing are moved quick and precisely, and power ratio control is little, reduce trouble, user cost is low.
Description of drawings

Fig. 2 is the barrier film two-way valve structure schematic representation (opening state) that surges.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises valve body 6, valve gap 3 and the barrier film 4 that is provided with inner chamber, valve gap 3 is installed on the valve body 6, valve gap 3 is provided with control mouth 7, barrier film 4 is installed between valve body 6 and the valve gap 3, form a diaphragm chamber 301 between barrier film 4 and valve gap 3, spring 2 supports and is contained between valve gap 3 and the barrier film 4, promotes barrier film 4 by the auxiliary pressure liquid source of controlling mouth 7 of the elastic force of spring 2 and closes.The two ends of valve body 6 are provided with water intake 1 and water outlet 5, be provided with sealing strip 8 in valve body 6 inner chambers between water intake 1 and the water outlet 5, in the time of in off position, under the elastic force effect of the pressure liquid source of controlling mouth 7 and spring 2, barrier film 4 is against on the sealing strip 8, closes being communicated with between water intake 1 and the water outlet 5.In the present embodiment, water intake 1 and water outlet 5 are provided with flange plate, are used for the installation of valve.
In use, the control valve of barrier film Twoway valves as water-treating equipment water intake, water outlet and sewage draining exit flow direction surges, the control mouth 7 of barrier film Twoway valves of surging connects miniature electromagnetic valves, miniature electromagnetic valve is connection control system respectively, while miniature electromagnetic valve Bonding pressure fluid supply (pressure liquid source can be the pressured fluid at water intake 1 place, also can be the external source pressured fluid).When needs are closed when surging the barrier film Twoway valves, the control miniature electromagnetic valve, make pressured fluid from control mouthfuls 7 enter valve gap 3 and barrier film 4 between diaphragm chamber 301, under the double action of fluid pressure and spring 2, make barrier film 4 press to sealing strip 8 places, thereby close the flow channel between water intake 1 and the water outlet 5, when water intake 1 enters the liquid of pressure, can't circulate enters water outlet 5, therefore can cut off fast flowing of liquid, plays closing function.
When needs are opened when surging the barrier film Twoway valves, the control miniature electromagnetic valve, closing control mouth 7 is connected with pressure liquid source, and the liquid in the diaphragm chamber 301 can be discharged by miniature electromagnetic valve from control mouth 7; Under the pushing of water intake 1 pressured fluid, barrier film 4 is lifted leave sealing strip 8, water intake 1 forms the flow channel that surges with water outlet 5, thereby has opened valve, discharges simultaneously the liquid in the diaphragm chamber 301.
Compare with existing electronic, Pneumatic butterfly valve, ball valve, the barrier film Twoway valves that surges does not have valve rod, sealing gasket, directed seat, valve block component, and unique parts are exactly barrier film in the flow channel, so there are not the phenomenons such as corrosion and locking, have higher stability, rate of fault is relatively low.Surging the barrier film Twoway valves can be supporting for water-treating equipment such as self-cleaning filter, common husky filters, can be used as water intake control valve, water outlet control valve, the use of sewage draining exit control valve, opening and closing are quick blanking time, are generally just can the finish the work second switching of mode of 2-5.Compare with electropneumatic butterfly valve, the ball valve of equal bore specification, every power only needs tens watts, and many to be installed in parallel user cost cheap.In addition, because the maintaining part is few, unique easily damaged parts is exactly barrier film, and for the user, it is minimum to use overall cost to have dropped to, and has made the life-span can be more than 5 years.
