Technical field
The utility model relates to and is a kind ofly arranged on the throttling of water mixing valve feed-water end and the valving of filtration, is suitable for water heater and uses.
Background technique
In the market, comprise the feed-water end of the water mixing valve of thermostatic valve to balance the intake pressure of hot and cold water, most employing installs pressure regulator valve additional in addition at high-pressure water inlet end, and to the poor area of water quality, especially uses the thermostatic valve higher to water quality requirement, then must carry out water filtration simultaneously, like this, should pressure regulation filter again, solution is all adopt separately to carry out usually, or with mixing valve split, another feeder apparatus is implemented.Like this, device can be made complicated, and cost improves.My patent No. is the technology of 201320573418.2, provides a kind of throttling and filter apparatus configuration, but it be arranged on water inlet switch after, have its narrow limitation.
Model utility content
The utility model is on the basis of above-mentioned patent, provide and be a kind ofly arranged on the throttling of water mixing valve feed-water end and the valving of filtration, this device is arranged near the valve body of the connecting part of valve body and water intake, can be made of one with valve body, certainly also can make split type, structure is simple, easy to operate, cost is low, of many uses.
The utility model improves above-mentioned patented technology, owing to being generally that cold water pressure is higher than heat hydraulic pressure, then only pressure regulation can be set to cooling water inlet end and add filtration, and the hot water end of low pressure is only filtered, vice versa, if certainly pressure at two ends height be can not determine, then two ends should install pressure regulation additional simultaneously add filtration.
The utility model is except comprising intake pipe 1 and the water intake L of the formula at a right angle of mixing valve, the intake pipe 1 being also included in formula at a right angle is arranged another and be opened on outer modulating valve tube chamber F and regulating spool 2, swivel nut 3 and filter screen 4, modulating valve tube chamber F becomes vertical relation with the pipeline of water intake L, and straight-through mixing valve, in modulating valve tube chamber F, regulating spool 2 is set, the step that it is conditioned bottom valve tube chamber F is spacing with the swivel nut 3 being installed on this lumen open place, make to have to pass through this regulating spool 2 from the water inlet of water intake L, just can enter in mixing valve, regulating spool 2 is tubular cavitys that top and driving lever connect, its periphery and modulating valve tube chamber F match, be slidably matched during rotation, a window is opened in its periphery, pass into inner chamber, size and water intake match, it accounts for center of circle angle and is at least less than 180 °, window place inserts filter screen 4, water can pass filter screen 4, enter inner chamber, then go out from chamber underflow, swivel nut 3 is pierced on its top, modulating valve tube chamber F, seal ring is had by it and outside seal between regulating spool 2 and swivel nut 3, spiral shell cutter can be inserted in regulating spool 2 top makes it rotate, also its top can be made to stretch out swivel nut 3, knob is installed, spacing or the spacing mark of certain angular turn is set between regulating spool 2 and modulating valve tube chamber F, when regulating spool 2 rotates in this angular range, can realize from closedown, be opened to the adjustment of flow of inlet water, when the outside water inlet of closedown, screw out swivel nut 3, take out regulating spool 2 and can extract filter screen out, be convenient to cleaning, in order to using again.
The intake pipe 1 that also above-mentioned modulating valve tube chamber F can be arranged on formula at a right angle is in the other end of same axis with water intake L, and now, the flow direction of water is the bottom flowing into regulating spool 2 from intake pipe L, then flows into mixing valve from the window of its sidewall.
Above-described regulating spool 2 is all the tubular cavity that upper end and driving lever connect, if thus cleaned filter screen 4 must take out regulating spool 2, again from wherein extracting filter screen 4 out, like this, the total valve then must closed in advance before intake pipe is just passable, the utility model additionally provides need not close the structure that water inlet total valve can take out filter screen 4, namely above-mentioned regulating spool 2 is made up of modulating valve core retainer plate 6 and modulating valve core bar 7 two-part, during to take out filter screen 4, can first screw out swivel nut 8, pull down modulating valve core bar 7, filter screen 4 can be extracted out from modulating valve core retainer plate 6.
Another technological scheme of the present utility model is:
It is except comprising intake pipe 1 and the water intake L of the one-tenth straight-through type of mixing valve, the intake pipe 1 being also included in into straight-through type arranges one section of modulating valve tube chamber F and regulating spool 2 intersected vertically near valve body, swivel nut 3, filter screen 4 and inner sleeve 5, the lumen diameter of modulating valve tube chamber (F) is greater than into water lumen diameter, in this tube chamber, setting coincide with it and is positioned the inner sleeve 5 of the circular tube shaped of this tube chamber, inner sleeve 5 tube wall have mutually every the two through hole of 180 °, each through hole its account for center of circle angle and be at least less than 90 °, this holes is concentric with water inlet pore, in inner sleeve 5, regulating spool 2 is set again, regulating spool 2 is tubular cavitys that upper end and driving lever connect, its periphery and inner sleeve 5 match, be slidably matched during rotation, regulating spool 2 arranges mutually every the two through hole of 180 ° on its cylindrical shell, pass into its inner chamber, it accounts for center of circle angle and is at least less than 90 °, size is mated with the through hole of inner sleeve 5, inner chamber inserts filter screen 4, the shaft axis of filter screen 4 plane and holes is perpendicular, the swivel nut 3 that inner sleeve 5 and regulating spool 2 are installed in this lumen open place is spacing, swivel nut 3 is pierced on regulating spool 2 top, modulating valve tube chamber F, seal ring is had it and the external world to be sealed between regulating spool 2 and swivel nut 3, spiral shell cutter can be inserted in regulating spool 2 top makes it rotate, also its top can be made to stretch out swivel nut 3, knob is installed, rotary spacing from 0 to 90 ° or mark are set between regulating spool 2 and modulating valve tube chamber F, when regulating spool 2 rotates in this angular range, can realize from closedown, be opened to the adjustment of flow of inlet water, when the holes of the holes with inner sleeve 5 that turn to regulating spool 2 is concentric with tube chamber of intaking, flow is maximum, screw out swivel nut 3, take out regulating spool 2, therefrom extract filter screen out, be convenient to cleaning, in order to using again.
Regulating spool 2 described in the program is tubular cavitys that upper end and driving lever connect, if thus cleaning or replacing filter screen 4 must take out regulating spool 2, again from wherein extracting filter screen 4 out, like this, the total valve then must closed in advance before intake pipe is just passable, and the utility model provides need not close water inlet total valve and namely take out filter screen 4.
The one stage adjust valve tube chamber F that the intake pipe 1 of itself and straight-through type intersects vertically, two-port is all opened, regulating spool 2 and inner sleeve 5 are limited in modulating valve tube chamber F by swivel nut 3 and end blind nut 9 jointly, if open end blind nut 9, filter screen 4 can be taken out easily, due to inner sleeve 5 be conically slidably matched with regulating spool 2, thus can better realize self throttle down to carry out cleaning and filtering.
In sum, the utility model provides and is a kind ofly arranged on the throttling of water mixing valve feed-water end and the valving of filtration, and structure is simple, and easy to operate, cost is low, of many uses.
