Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of automatic throttle.
Background technique
Tap water refers to the water for people's life, production and application meeting respective standard by producing after water treatment plants purification, sterilization.Domestic water draws rivers and lakes and underground water mainly through the water intake pumping station of water factory, surface water, by waterworks according to " national Drinking Water related sanitary standard ", through the process of the technological processes such as precipitation, sterilization, filtration, be transported to each user finally by Energy Saving Measures of Pumping Station.
Using water pump to transport in the process of tap water, there is various problem in the pressure instability that usually can export because of water pump; if pressure increases suddenly; flow velocity from the beginning just increases thereupon, due to the inertia of tap water, and the words that flow velocity is too fast; tap water will produce collision to pipeline; occur liquid hit phenomenon, the lighter makes pipeline generation tremble, and severe one pipeline will break; cause tap water to leak, cause water resource waste.
Summary of the invention
The object of this invention is to provide a kind of automatic throttle, can automatically adjust according to the pressure change of tap water, prevent liquid hit phenomenon.
The invention provides a kind of base case: a kind of automatic throttle, comprise valve yoke, be positioned at the pressure regulating cavity above valve yoke and the rotary part being positioned at pressure regulating cavity, valve yoke comprises valve inlet and valve export, also comprise the adjusting portion in the fluid chamber be positioned at before rotary part and the outlet port being positioned at fluid chamber, fluid chamber is communicated with pressure regulating cavity; Adjusting portion comprises fluid forces portion and gear adjusting portion, the piston rod that fluid forces portion comprises piston and is connected with piston, is provided with elastic component, baffle plate and the first tooth bar above piston rod successively; Gear adjusting portion comprises the first gear, the second gear and the regulator plate that engage with the first tooth bar from bottom to up, and regulator plate is provided with the second tooth bar with the second gears meshing near one end of the second gear, the other end of regulator plate is communicated with pressure regulating cavity.
Working principle and beneficial effect are: regulate rotary part, and start water pump, tap water is flowed to valve export from valve inlet by rotary part.When the pressure of tap water increases suddenly, part of running water can be diverted in fluid chamber.Tap water promotes piston advances forward, and elastic component is in compressive state under the effect of baffle plate, piston driving piston rod travels forward, rack drives first gear above piston rod rotates counterclockwise, second gear rotates clockwise, because the second gear engages with the second tooth bar, second gear driven regulator plate lower end moves downward, increase the area of tap water by pressure regulating cavity, thus reduce the pressure of tap water, reach the effect of adjustment pressure, when pressure adjusting is normal value, elastic component returns to form, promotion piston and piston rod set back, thus regulator plate is set back.
The present invention, by the fluid forces portion in fluid chamber and gear adjusting portion, makes, when tap water pressure becomes large, can realize carrying out pressure release to the pressure in pressure regulating cavity, thus prevent liquid hit phenomenon.
Further optimized project one for base case: rotary part comprises valve body, the valve that is positioned at the valve seat of body base and is positioned at valve seat two ends leads to plate, and the both sides that valve leads to plate are provided with chute, and valve seat and valve lead to plate and be slidably connected.In order to open water pump, can rotary valve be passed through, touching valve seat and promoting valve seat and sliding, thus Open valve, tap water can be passed through.
Further optimized project two for optimized project one: valve leads to plate and comprises left logical plate and the right side leads to plate, and the lower end of left logical plate is provided with the first cavity body, and the upper end of right logical plate is provided with the second cavity body.In order to effectively open water pump, the lower end of left logical plate is provided with the first cavity body, and the upper end of right logical plate is provided with the second cavity body, when valve seat is positioned at neutral position, and valve closing, when valve seat is upwards or when moving downward, can Open valve, make throttle valve more convenient.
Further optimized project three for base case: elastic component is stage clip.Due to when pressure is large, piston can promote piston rod makes elastic component be in compressive state, and regulated afterwards, elastic component can set back, and for this reason, elastic component is set to stage clip.
Further optimized project four for optimized project three: compression spring sleeve is face on the piston rod.In order to make piston set back after adjustment pressure, so compression spring sleeve face on the piston rod, piston rod can be made to set back.
For further optimized project five: the first gear and the second gear outer gearing of base case.During in order to ensure that pressure becomes large, regulator plate moves downward, so arrange the first gear and the second gear outer gearing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is structural representation of the present invention.
