Abstract
The utility model provides a flow control elbow, includes that elbow body, valve block, sealing washer no. 1, sealing washer no. 2 and back -moving spring constitute, the elbow body is 180 revolving structure, except the flowing water passageway, still is provided with the flow control cavity between water inlet and the delivery port, flow control cavity upper portion is equipped with the valve block, the valve block passes through sealing washer no. 1 and realizes going up the lower seal with sealing washer no. 2, the back -moving spring is located flow control cavity lower part, back -moving spring upper portion is fixed in the bottom of valve block, and the lower part is fixed on the piece is grabbed to the back -moving spring that the water inlet located to set up, the utility model discloses simple structure can be to controlling the flow of water more than certain pressure, and effectual having avoided leads to the change of a discharge because of the water supply variation in pressure.
Description
Technical field
The utility model relates to water supply installation technical field, particularly a kind of flow control elbow.
Background technique
In the water system of reality, often because pressure of supply water different often causes user, the flow of water after tap of fetching boiling water is different, especially on some automatic water supply systems, all adopt solenoid valve to control the opening and closing of water, because pressure of supply water changes the waste that the current causing water outlet either large or small can cause water, also the carrying out of inconvenient related work.
Model utility content
The utility model, for the deficiencies in the prior art, provides and can change and a kind of flow control elbow of flow automatic regulation according to pressure of supply water.
The utility model is solved by following technical proposals: a kind of flow control elbow, comprise elbow body, valve block, seal ring one, seal ring two and stretched spring composition, described elbow body is 180 ° of revolving structures, except pipelined channel, Flow-rate adjustment cavity is also provided with between water intake and water outlet, described Flow-rate adjustment cavity top is equipped with valve block, described valve block realizes upper-lower seal by seal ring one and seal ring two, described stretched spring is positioned at Flow-rate adjustment cavity bottom, described stretched spring top is fixed on the bottom of valve block, bottom is fixed in the stretched spring pulldown of water inlet setting.
Further, described Flow-rate adjustment cavity top is rectangular cross-section, bottom is circular cross-section, described rectangular cross-section is equal with described valve block upper hemispherical field shape rectangular sheet thickness width, the circular cross-section of bottom is equal with described valve block lower cylindrical end external diameter, and the rectangular sheet top, upper hemispherical field of described valve block is provided with banking stop.
The utility model realizes Flow-rate adjustment like this, when installing, there is no the situation of hydraulic pressure, stretched spring by valve block toward drop-down, now limited of valve block limits, at this moment, the flow of valve block on water outlet does not affect, when hydraulic pressure slowly rises, because the circular section bottom valve block is larger than the rectangular cross-section area on valve block top, so hydraulic pressure is greater than valve block top to valve block base pressure, valve block is up pushed up, at this moment, stretched spring can be offset bottom a part of valve block and the pressure difference on valve block top to the pulling force of valve block, when pressure bottom valve block is less than or equal to pulling force and the valve block upper pressure of stretched spring, valve block keeps motionless, when pressure bottom valve block is greater than pulling force and the valve block upper pressure of stretched spring, valve block is up pushed away, the passage of water outlet reduces by the upper hemispherical field pattern rectangular sheet on valve block top, thus reach the reduction of water flow.
The utility model structure is simple, can control more than certain pressure to the flow of water, effectively avoids the variation causing water flow because of the change of pressure of supply water.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: as shown in Figure 1, a kind of flow control elbow, comprise elbow body 1, valve block 2, seal ring 1, seal ring 24 and stretched spring 5 form, described elbow body 1 is 180 ° of revolving structures, except pipelined channel 1.1, Flow-rate adjustment cavity 1.4 is also provided with between water intake 1.2 and water outlet 1.3, described Flow-rate adjustment cavity 1.4 top is equipped with valve block 2, described valve block 2 realizes upper-lower seal by seal ring 1 and seal ring 24, described stretched spring 5 is positioned at Flow-rate adjustment cavity 1.4 bottom, described stretched spring 5 top is fixed on the bottom of valve block 2, bottom is fixed in the stretched spring pulldown 1.5 of water intake 1.2 place setting.
Described Flow-rate adjustment cavity 1.4 top is rectangular cross-section 1.41, bottom is circular cross-section 1.42, described rectangular cross-section 1.41 is equal with described valve block 2 upper hemispherical field shape rectangular sheet 2.1 thickness width, the circular cross-section 1.42 of bottom is equal with described valve block 2 lower cylindrical end 2.2 external diameter, and rectangular sheet 2.1 top, upper hemispherical field of described valve block 2 is provided with banking stop 2.3.
The utility model realizes Flow-rate adjustment like this, when installing, there is no the situation of hydraulic pressure, stretched spring 5 by valve block 2 toward drop-down, now valve block 2 limited 2.3 limits, at this moment, the flow of valve block 2 on water outlet 1.3 does not affect, when hydraulic pressure slowly rises, because the circular section bottom valve block 2 is larger than the rectangular cross-section area on valve block 2 top, so hydraulic pressure is greater than valve block 2 top to valve block 2 base pressure, valve block 2 is up pushed up, at this moment, the pulling force of stretched spring 5 pairs of valve blocks 2 can be offset bottom a part of valve block 2 and the pressure difference on valve block 2 top, when pressure bottom valve block 2 is less than or equal to pulling force and valve block 2 upper pressure of stretched spring 5, valve block 2 keeps motionless, when pressure bottom valve block 2 is greater than pulling force and valve block 2 upper pressure of stretched spring 5, valve block 2 is up pushed away, on valve block, the passage of water outlet 1.3 reduces by the upper hemispherical field pattern rectangular sheet 2.1 of 2, thus reach the reduction of water flow.
Protection domain of the present utility model includes but not limited to above mode of execution; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.
