Abstract
The utility model relates to a water supplying and draining apparatus, particularly a full-automatic energy-saving valve without maintenance. The full-automatic energy-saving valve without maintenance is composed of a left valve body, a right valve body, a valve body reinforcing rib, a big valve plate positioning rod, small valve plate shaft pins, a big valve plate, a big valve plate shaft pin, etc., wherein the end parts of two inner sides of the left valve body are respectively provided with the shaft pins which are used for installing the small valve plate; the inner end surface of the left valve body and the lower plane surface of the small valve plate are provided with annular grooves; the middle part of the inner end of the left valve body is provided with the valve body reinforcing rib, the upper plane surface of the valve body reinforcing rib is provided with two straight long grooves, and the middle part of the reinforcing rib is provided with the shaft pin for connecting the big valve plate; the lumbar part of the inner cavity of the right valve body is provided with the big valve plate positioning rod; the middle part of the big valve plate is provided with a leakage opening which plays the function of water hammering elimination; the front end part of the big valve plate and the bottom end part of the small valve plate are respectively provided with a touch block, before the big valve plate contacts the inner end surface of the left valve body, the touch block of the big valve plate is closed to the touch block of the small valve plate to compel the small valve plate to fall down and the small valve plate just seals the leakage opening in the middle part of the big valve plate.
Description
Technical field
The utility model relate to a kind ofly give, drainage equipment, especially a kind ofly automatically be excused from a college course energy-conservation valve.
Background technique
At present, water valve develops into the structural type of Automatic Control by structural type manual, electronic, pneumatic, the control of surging both at home and abroad, but, come the control valve valve plate to open and close the structural type of action for the active force that utilizes the inlet/outlet flowing medium, also have only two kinds of diaphragm type and water vat piston types.But these two kinds of form water valves all exist complex structure, the medium circulating resistance is big, energy loss is big defective.
Summary of the invention
The purpose of this utility model just provide a kind of simple in structure, resistance to water-flow is little, energy saving, move reliable and stable, good sealing effect, that can eliminate water hammer automatically is excused from a college course energy-conservation valve.
The technical solution of the utility model is as follows: a kind ofly automatically be excused from a college course energy-conservation valve, comprise left and right valve body, valve body stiffening rib, big valve plate positioning rod, big valve plate, little valve plate and large and small valve plate pivot pin etc.Wherein, two inner ends at left valve barrel, be respectively equipped with the hinge type pivot pin that little valve plate is installed, be provided with the circular groove that seal ring is installed on the left valve barrel interior edge face and on the little valve plate lower plane, be provided with a valve body stiffening rib at middle part, left valve barrel the inner, the plane is provided with two straight elongated slots on stiffening rib, is provided with two hinge type pivot pins that connect big valve plate at the stiffening rib middle part.Be provided with big valve plate positioning rod at the right valve barrel waist, be provided with leakage hole, rise and eliminate water hammering at big valve plate middle part.Respectively be provided with a collision block at big valve plate front end and little valve plate bottom, before big valve plate was about to contact the left valve barrel interior edge face, big valve plate collision block forced little valve plate to fall by last little valve plate collision block, just in time sealed the leakage hole in the middle of the big valve plate.
The utility model had not both been wanted diaphragm chamber and water vat piston drive valve valve plate and had been opened and closed, and had multiple functions such as safety check, stop valve and water-hammer arrester again.Particularly resistance to water-flow is little, energy saving.No matter at any time have a power failure, termination of pumping, valve can both be closed automatically, need not manual operation.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is a structure plan view of the present utility model.
Embodiment
As shown in the figure, a kind ofly automatically be excused from a college course energy-conservation valve, comprise left valve barrel 1, right valve barrel 2, stiffening rib 3, positioning rod 4, little valve plate pivot pin 5, big valve plate 6, little valve plate 7, big valve plate pivot pin 8, big valve plate collision block 9 and little valve plate collision block 10 etc., wherein be positioned at 1 liang of inner end of left valve barrel, be respectively equipped with the pivot pin 5 that little valve plate 7 is installed, be provided with the circular groove that seal ring is installed on the interior edge face of left valve barrel 1 and on little valve plate 7 lower planes.Inner middle part at left valve barrel 1 is provided with a valve body stiffening rib 3, the plane is provided with two straight elongated slots that Stamping Steel Ribbon is installed on stiffening rib 3, be provided with two pivot pins 8 that connect big valve 6 at stiffening rib 3 middle parts, be provided with the positioning rod 4 of big valve plate 6 at the waist of right valve barrel 2, be provided with leakage hole at big valve plate 6 middle parts, be provided with collision block 9 at big valve plate 6 front ends, be provided with collision block 10 in little valve plate 7 bottoms.On the stiffening rib 3 of left valve barrel 1, in the straight elongated slot on plane the rubber weather strip water shutoff has been installed.In the interior edge face circular groove of left valve barrel 1 and in the circular groove of little valve plate 7 lower planes, the ring-shaped rubber seal ring is housed respectively, can effectively water seal be lived.
Before starting mode of pump, valve is in the static pressure closed condition, behind starting mode of pump, water enters from valve body 1 left end, and under flow of inlet water and pressure effect, two little valve plates 7 are at first opened, increase along with flow and pressure, two big valve plates 6 are opened to Nominal Width, and are close to positioning rod 4, and the medium clear that allows water pump extrude flows to right valve barrel 2 outlets unimpededly.
When water pump was stopped, the valve inlet flow is poly-to stop, and big valve plate 6 hurtles down under deadweight and backwater percussion, cuts off most refluence medium.When big valve plate 6 will contact left valve barrel 1 interior edge face, the collision block 9 of big valve plate 6 front ends leans on mutually with the collision block 10 of little valve plate 7 bottoms, force little valve plate 7 to fall, Leak hole in the middle of the big valve plate 6 is sealed, the large and small valve plate of this moment tightly is attached on the interior edge face of left valve barrel 1 under the pressure of return water effect.Valve returns to the static pressure closed condition before the starting mode of pump again.
