Abstract
The utility model discloses a single electromagnetic servo double pulsator, consisting of a shell, a valve core and a pulsation chamber cover, wherein, the shell is provided with a main pulsation output port, an auxiliary pulsation output port and a vacuum interface; a main pulsation chamber and an auxiliary pulsation chamber are arranged between the valve core and the pulsation chamber cover; a pulsation membrane is arranged near the valve core in the main pulsation chamber and the auxiliary pulsation chamber; an upper inlet communicated with air and a lower inlet communicated with negative pressure air source are arranged in the main pulsation chamber; an electromagnetic valve is arranged between the upper inlet and the lower inlet; and the main pulsation output port is communicated with the auxiliary pulsation chamber to form a pulsation signal feedback channel. In the utility model, the electromagnetic valve controls the pressure in the pulsation chambers to push the pulsation membrane to work; the pulsation ratio can be adjustable, the pulsation frequency is stable, the operation of the single electromagnetic servo double pulsator is not influenced by seasons and environmental temperature, the failure rate is low, and the milking efficiency is high, thus solving the problem that a milking machine can not work normally as the damping hole of the pulsator is easy to be blocked.
Description
One, technical field
The utility model relates to the pulsator of the usefulness of milking, specifically is the two pulsators of a kind of single magnetic valve servo-type.
Two, background technology
Pulsator is a requisite critical component on the milking equipment, the good and bad operating efficiency and the technical performance that directly influences milking machine of its quality and performance.At present the pulsator that uses on the milking equipment mostly is to adopt gas damp type pulsator, and pulsation film in the pulsation chamber or pulsation leather bag all are to promote pulsation film or the work of pulsation leather bag by the plus or minus of the damping hole feedback body pressure of calming the anger.The damping hole diameter of this pneumatic pulsator is less than normal, has only about 0.7mm, is often stopped up by dust, dirt; Especially use winter at Han Qu or severe cold district, cause damping hole often to be stopped up by rime ice because temperature is low.After damping hole was blocked, pulsator was not pulsed, and the milking machine cisco unity malfunction is because of the blocked cisco unity malfunction of damping hole is the more recurrent fault of pneumatic pulsator.
Three, summary of the invention
The purpose of this utility model is to provide single magnetic valve servo-type of using on a kind of milking equipment two pulsators at the problems referred to above, and it is easily blocked and cause the problem of milking machine cisco unity malfunction to solve the pulsator damping hole.
The utility model is achieved through the following technical solutions: the two pulsators of single magnetic valve servo-type are made of housing, spool, pulsation chamber cover, there is master pulse to move delivery outlet, the moving delivery outlet of epiphysis, vacuum interface on the housing, major and minor pulsation chamber is arranged between spool and the pulsation chamber cover, near the spool place pulsation diaphragm is housed in the major and minor pulsation chamber, upper inlet of connecting with atmosphere and the lower inlet of connecting with the negative pressure source of the gas are arranged in the moving chamber of master pulse, in the middle of upper and lower two inlets magnetic valve is housed, the moving delivery outlet of master pulse communicates with the moving chamber of epiphysis and constitutes the fluctuating signal feedback channel.
The good effect that the utlity model has: the two pulsators of single magnetic valve servo-type use the pressure in the solenoid control pulsation chamber, be used for promoting the work of pulsation diaphragm, its pulsation is stablized than adjustable, ripple frequency, is not subjected to the influence of season, environmental temperature, fault rate is low, the milking efficiency height.

1 housing among the figure, 2, the 2a spool, 3 master pulses move the chamber, and the 3a epiphysis moves the chamber, 4 master pulse dynamic diaphragms, 4a epiphysis dynamic diaphragm, 5 master pulses move delivery outlet, and 6 epiphysis move delivery outlet, 7 vacuum interfaces, 8,8a pulsation chamber cover, 9 upper inlets, hand-hole under the 9a, 10 fluctuating signal feedback channels, 11 magnetic valves, 12 atmosphere imports.
Five, embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 provides the overall structure schematic diagram of the two pulsators of single magnetic valve servo-type, and as shown in the figure, the two pulsators of single magnetic valve servo-type are by housing 1, spool 2,2a, pulsation chamber cover 8,8a constitute, and have master pulse to move delivery outlet 5, the moving delivery outlet 6 of epiphysis, vacuum interface 7 on the housing 1; Have master pulse to move chamber 3 between spool 2 and pulsation chamber cover 8, master pulse is equipped with pulsation diaphragm 4 near spool 2 places in the moving chamber 3.Between spool 2a and pulsation chamber cover 8a, there is epiphysis to move chamber 3a, near spool 2a place pulsation diaphragm 4a is housed in the moving chamber 3a of epiphysis.Master pulse has upper inlet 9 and lower inlet 9a in the moving chamber 3, and upper inlet 9 is connected with atmosphere, and lower inlet 9a and negative pressure source of the gas are connected.Upper inlet 9 and the middle magnetic valve 11 that is equipped with of lower inlet 9a, the moving delivery outlet 5 of master pulse communicate with the moving chamber 3a of epiphysis and constitute fluctuating signal feedback channel 10.The channel diameter of the upper inlet 9 that communicates with atmosphere and the lower inlet 9a channel diameter that communicates with the negative pressure source of the gas are 1.5～2.5mm.
Fig. 2 is a solenoid valve controller operation principle block diagram in the utility model, according to shown in Figure 2, the control circuit of solenoid valve controller does not have the stable state on-off circuit by one group to be controlled two groups of monostable switch circuit and constitutes, and two groups of monostable switch circuit respectively drive pulsator work by one group of emitter follower output back.Producer's processing be chosen or be entrusted to magnetic valve 11 can by market.
Magnetic valve has two actions when energising, and the one, logical atmosphere, stifled vacuum; The 2nd, logical vacuum, stifled atmosphere.When the logical atmosphere of magnetic valve, stifled vacuum, pulsation film 4 is under atmospheric pressure, overcome the elastic force of diaphragm, making diaphragm promote spool 2 makes it that atmosphere is blocked, the moving delivery outlet 5 output vacuum of master pulse this moment, enter vacuum in the meanwhile secondary 3a of pulsation chamber, inhale the moving film 4a of moving epiphysis its drive spool is blocked vacuum, the moving delivery outlet 6 output atmosphere of epiphysis this moment.Principle is just in time opposite with said process when the logical vacuum of magnetic valve, stifled atmosphere.A pulsation beat finishes second, and next pulsation beat repeats thereupon, and continuous pulsation beat, perseveration drive pulsator and carry out work.
