Abstract
The utility model relates to a pressure relief regulating device for a diaphragm pump of a direct drinking machine, which comprises a pump head cover of a diaphragm pump, a spring, a spring sleeve, and a diaphragm sleeve which is arranged in the spring sleeve, wherein a water inlet hole in the pump head cover is communicated with a high-pressure chamber in a pump body. One end of a pressure relief hole is communicated with the cavity of the spring sleeve, and the other end of the pressure relief hole extends out of the pump body. A hole is the spring sleeve is provided with inner screw threads. With the structural design, the purposes that the regulating device can stably regulate hydraulic pressure and makes no noise are reached.
Description
Affiliated technical field:
The utility model relates to a kind of diaphragm pump, particularly relates to the pressure release regulator regulating device of a kind of straight drink machine with diaphragm pump.
Background technique:
At present, water purifier has entered town dweller's huge numbers of families, brought the potable water that makes things convenient for clean hygiene to people, but the fault that water purifier occurs some parts damages sometimes or oneself can not get rid of, the result just must get producer and keep in repair and the parts that more offer the same old stuff but with a different label, the phenomenon that motor burns out appears sometimes as existing water purifier, trace it to its cause, be because due to the structure composition and working principle of water purifier: diaphragm pump is arranged in the water purifier, diaphragm pump includes the pump head lid, separate in the pump head lid high low pressure water cavity is arranged, high, the low pressure water cavity has out, water intake passes to outside the lid, and diaphragm pump is furnished with motor, and the motor rotor high speed rotating drives diaphragm pump and draws water supercharging (owing to want saturating (RO) film of through carburizing, so diaphragm pump hyperbaric chamber discharge pressure is higher, reach 70-120psi), exceed rated working pressure for preventing discharge pressure, existing diaphragm pump covers at pump head all pressure relief device, what adopt is circulation pressure release design, promptly in the direct pressure-releasing chamber of high pressure water in the hyperbaric chamber.Though this design water only circulates in pump and does not leak, directly pressure release when intake pressure is low, but then can not pressure release when if intake pressure is higher than the working pressure of diaphragm pump, and this situation makes motor load excessive and burn out rotor sometimes, and burst diaphragm easily and then cause the seepage phenomenon, can cause security incident when serious.
The patent No. is a kind of water purifier diaphragm pump of 0320905.5, adopted to cover and had a blind hole at diaphragm pump head, the hole inwall has internal thread, the bottom, hole has the hole and communicates with high-pressure water chamber, on hole wall, also have horizontal water outlet and lead to outside the lid, from the bottom of the hole to outside be followed successively by chock plug sealing rubber pad, pressure release spring, sealing rubber pad and leak stopping screw.This regulator since the horizontal water outlet of can regulate pressure relief device be directly and lid be interlinked to the outside rather than let out low-pressure cavity, be that back pressure is a barometric pressure, no matter how many intake pressures has, can not influence pressure release, will pressure release arrive outside the lid as long as the hydraulic pressure in the high-pressure water chamber reaches the pressure release value of can regulate pressure relief device, can not influence the normal operation of motor.But the leak stopping screw of this pressure relief device is because direct and spring, screw easily puts in the spring, spring directly contacts with the internal thread that the hole inwall has, because spring is smaller, spring easily sticks in the thread groove, causes spring undesired flexible, and the diameter of spring is smaller again again, regulate pressure instability, and produce noise.
Summary of the invention:
The purpose of this utility model provide a kind of can stable regulation hydraulic pressure, do not have noise, easy for installation, spring can not fallen into the pressure release controlling device in the spiral shell mosquito hole into.
In order to achieve the above object, the utility model by the following technical solutions: the utility model comprises diaphragm pump head lid, spring and spring spool, and the barrier film sleeve places in the spring spool chamber; The spring lower end is with spring compressor, and the spring upper end is pressed and is equipped with spring cup, and the column on the spring cup puts in the spring eye; The spring that is equipped with spring compressor and spring cup places in the inner chamber of spring spool; Adjusting screw rod is meshed with the internal thread of spring spool endoporus, and one of adjusting screw rod contacts with spring cup.The interior hyperbaric chamber of water inlet in the diaphragm pump pump cover and the pump housing is connected.Relief hole one end is connected with the spring spool chamber, and the other end stretches out outside the pump housing.Be provided with internal thread in the hole in the spring spool.
After adopting above technological scheme, spring of the present utility model slides in the inner chamber of spring spool, because of there not being screw thread in the inner chamber, and it is smooth, do not fall into into or jammed problem so spring does not exist, both ends of the spring all has spring compressor again again, so adjusting screw rod can not stick in the spring, adjusting screw rod passes through the engagement of the interior nut line of spring spool endoporus, thereby can promote the extending amount of spring up and down.So after adopting above technological scheme, this controlling device is adjusting hydraulic pressure very stably, and noise free.
