Description
(1) technical field
The utility model relates to a kind of wall plastering apparatus.
(2) background technology
Wall plastering apparatus is used in coating and whitewashes occasion, is used for coating is delivered to the brushing cylinder from storage lacquer tube automatically, realizes continuous brushing operation.
The patent No. provides a kind of conveying equipment of coating for the United States Patent (USP) of US5096392, the brushing cylinder is installed in this conveying equipment cooperation just becomes wall plastering apparatus, it comprises the coating transfer pipeline and is installed in diaphragm pump on the coating transfer pipeline, a pressure-sensitive diaphragm that is used to respond to discharge pressure also is installed on the coating transfer pipeline, and is used to accept the microswitch of pressure-sensitive diaphragm distortion.In order to prevent that motor from operating under the high capacity excessively, the maximum delivery pressure that needs a pipeline of regulation, when the pressure on affacting pressure-sensitive diaphragm reaches maximum delivery pressure, pressure-sensitive diaphragm will produce bigger distortion, and this distortion will promote microswitch, and the microswitch action is also cut off motor power, motor quits work, discharge pressure will no longer further increase, and along with brushing proceeding of operation, discharge pressure descends gradually.When discharge pressure drops to a certain degree, the distortion of pressure-sensitive diaphragm also is reduced to a certain degree, and microswitch resets, and motor power is connected, and opens motor once more.Hence one can see that, and this equipment is in running, and motor is opening and closing more continually, all can have a negative impact to motor itself and electrical network.In addition, in the moment of motor opening and closing, the flow of coating output is easy to produce sudden change, also produces very big influence for the stability of coating brushing work.
(3) summary of the invention
In order to overcome the deficiency that wall plastering apparatus in the prior art opens and closes motor more continually, the utility model provides the wall plastering apparatus of a kind of motor and delivery pump continuous operation.
The technical scheme in the invention for solving the technical problem is:
A kind of wall plastering apparatus, comprise the brushing cylinder, and one end be communicated with storage lacquer tube, the other end connects the coating transfer pipeline of brushing cylinder, on the described coating transfer pipeline diaphragm pump and drive motors thereof are installed, comprise that also an end is communicated with described coating transfer pipeline, the other end is communicated with the return line that tube is coated with lacquer in storage, control valve also is installed on the described return line; Described control valve comprises the valve body with inlet and liquid outlet, this valve body also has the valve pocket that is communicated with described inlet and liquid outlet, in the described valve pocket spool is arranged, described spool front end is butted on connection place of described inlet and valve pocket, offset and locate to form sealing surface, the spool end is connected with the rear end of valve body by preloading spring.
Further, described preloading spring equals specified discharge pressure in the coating transfer pipeline to the preload pressure of spool.
Further, the described valve body knob sleeve that also is threaded, the end of described valve body is equipped with rear end cap, and described rear end cap and described knob sleeve are affixed, and described preloading spring connects described spool and described rear end cap.
Further, described return line is connected on the coating transfer pipeline at diaphragm pump output rear.
Further, between rear end cap and the knob sleeve seal is installed.
Further, described seal is sealing mat and barrier film.
Further, be provided with sealing ring between described knob sleeve and the described valve body.
The utility model is carried coating by delivery pump in use.The manual adjustments knob sleeve, make the spool no longer inlet and the valve pocket of sealed valve body, thereby make coating be back to surge drum, the coating that transfers to the brushing cylinder is shunted, to play the effect that transfers to the coating flow of brushing cylinder of regulating via inlet, valve pocket and liquid outlet.When spool is butted on connection place of inlet and valve pocket, also be that spool is when being in closure state, when the coating discharge pressure of inlet enough big, during greater than the specified discharge pressure in the coating transfer pipeline, this coating discharge pressure will overcome the precompression of preloading spring, and spool is moved, and spool is the inlet and the valve pocket of sealed valve body no longer, produce the overflow effect, thereby the discharge pressure that has limited in the coating transfer pipeline improves further; When spool is not butted on connection place of inlet and valve pocket, also be that spool is when being in opening, when the coating discharge pressure of inlet enough big, during greater than the specified discharge pressure in the coating transfer pipeline, this coating discharge pressure also can overcome the precompression of preloading spring, makes spool spool and valve body sealing surface further away from each other, the unlatching that also promptly increases spool, increase coating is back to surge drum via inlet, valve pocket and liquid outlet flow, produce the overflow effect.Therefore, the specified discharge pressure of this device is that the precompression of spring is big more by the decision of the precompression of preloading spring, and the specified discharge pressure of this device is also just big more.In addition, the utility model be owing to can make spool be in opening or closure state by the manual adjustments knob, and can also regulate the degree of unlatching in opening.Therefore, when being necessary, this control valve can also be realized the reverse flow of liquid, and this has also brought convenience for cleaning with the back of wall plastering apparatus.
The beneficial effects of the utility model are: 1. motor and delivery pump all are continuous runnings, have avoided frequent keying.2. the utility model can also be regulated flow when having realized restriction maximum delivery pressure.
(4) description of drawings
Fig. 1 is a piping diagram of the present utility model.
Fig. 2 is the structural representation of control valve.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
