Abstract
The invention relates to the technical field of water meters, in particular to a pilot valve, which comprises a valve body, a miniature electric three-way valve, a diaphragm and a sealing plate, wherein the valve body comprises a water inlet pipe and a water outlet pipe; the water inlet pipe is communicated with one end of the miniature electric three-way valve through a water inlet pipeline; the water outlet pipe is communicated with the other end of the miniature electric three-way valve through a water outlet pipeline; the third end of the miniature electric three-way valve is communicated with a valve cavity of the valve body; a connecting rod is arranged in the valve cavity; a spring is connected outside the connecting rod in a sleeving way; one end of the connecting rod is connected with the middle part of the diaphragm; the lower part of the diaphragm is connected with the sealing plate; the water inlet pipe and the water outlet pipe of the valve body are separated by the sealing plate. According to the pilot valve, water flow in the water inlet pipe and the water outlet pipe is controlled by the miniature electric three-way valve, so that the control accuracy is high, and a zero-pressure difference leakage-free state can be achieved; the pressure control range is wide, and reduced pressure control in a high-pressure environment and a low-pressure environment can be realized.
Description
Technical field
The present invention relates to water meter technical field, particularly relate to a kind of pilot valve.
Background technique
Along with the continuous popularization of smart card techniques, the characteristics such as contact type intelligent card is convenient with it, safety oneself through being widely used in public transport, taxi, application as wet goods petit average.In the intelligent water rate toll collection applications that water meter and intelligent card reader are unified, user deposits the debt of certain number within a smart card in advance, during paying, user only needs to use smart card, the water resources usage data that the card reader unified with water meter provides according to water meter, from the debt that smart card memory is put, deduct matching amount, what just complete water rate pays process.
Pilot valve controls the control mechanism in other valve or element and a kind of Auxiliary valves used as a kind of, obtains in the industry and applies more and more widely.This type of valve is the functional valve of reduction valve external control pipeline core, for regulating the opening and closing of main valve, thus realizes the control to main valve downstream pressure.
Pilot valve majority of the prior art is Mechanical course, thinks and controls its opening and closing of hand rotation pilot valve air loaded down with trivial details, and more difficult accurate control.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and provide a kind of pilot valve, structure is simple, improves the Security of water meter entirety.
The present invention for achieving the above object, by the following technical solutions: a kind of pilot valve, comprise: valve body, miniature electric three-way valve, barrier film and sealing plate, described valve body comprises intake pipe and outlet conduit, described intake pipe is communicated with by inlet pipeline one end with described Miniature three-way valve, described outlet conduit is communicated with by the other end of rising pipe with described Miniature three-way valve, 3rd end of described Miniature three-way valve is communicated with the valve pocket of described valve body, connecting rod is provided with in described valve pocket, spring is socketed with outside described connecting rod, one end of described connecting rod is connected with the middle part of described barrier film, bottom and the described sealing plate of described barrier film connect, described sealing plate is separated by the intake pipe of valve body and outlet conduit.
Preferably, described barrier film is provided with fixed block, and described fixed block is connected with described connecting rod.
Preferably, described sealing plate both sides be oblique angle.
The invention has the beneficial effects as follows: structure of the present invention is simple, to be led to water inlet by miniature electric three-way valve and current in outlet conduit control, control accuracy is high, can reach zero pressure difference without leak condition; Pilot pressure is in extensive range, can realize Decompression Controlling in hyperbaric environment and environment under low pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, valve body; 2, miniature electric three-way valve; 3, barrier film; 4, sealing plate; 5, intake pipe; 6, outlet conduit; 7, valve pocket; 8, connecting rod; 9, spring; 10, fixed block; 11, inlet pipeline; 12, rising pipe.
Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of pilot valve, comprise: valve body 1, miniature electric three-way valve 2, barrier film 3 and sealing plate 4, described valve body comprises intake pipe 5 and outlet conduit 6, described intake pipe is communicated with one end of described Miniature three-way valve by inlet pipeline 11, described outlet conduit is communicated with the other end of described Miniature three-way valve by rising pipe 12, 3rd end of described Miniature three-way valve is communicated with the valve pocket 7 of described valve body, connecting rod 8 is provided with in described valve pocket, spring 9 is socketed with outside described connecting rod, one end of described connecting rod is connected with the middle part of described barrier film, bottom and the described sealing plate of described barrier film connect, described sealing plate is separated by the intake pipe of valve body and outlet conduit.Described barrier film is provided with fixed block 10, and described fixed block is connected with described connecting rod, for fixed connecting rod and barrier film.Described sealing plate both sides be oblique angle, reach better sealing purpose.
Working principle: when intake pipe is communicated with valve pocket by three-way valve, now, the rising pipe of three-way valve is in the state of closedown, identical with intake pipe hydraulic pressure in valve pocket, sealing plate is in the state of cut out, current do not enter into outlet conduit, when one end of the three-way valve on inlet pipeline is closed, valve pocket and three-way valve and rising pipe are opened, now, the hydraulic pressure in valve pocket will lower than the hydraulic pressure of intake pipe, sealing plate backs down by hydraulic pressure, current enter into outlet conduit, and now, pilot valve is in the state of unlatching.
Structure of the present invention is simple, to be led to and current in outlet conduit control by miniature electric three-way valve to water inlet, and control accuracy is high, can reach zero pressure difference without leak condition; Pilot pressure is in extensive range, can realize Decompression Controlling in hyperbaric environment and environment under low pressure.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
