Abstract
The utility model discloses an automatic pumping water valve, particularly applicable to the water-level control valve of automatic water charging in water box. The principle adopted by the valve is similar to the existing products, but the utility model arranges a seal body in the valve and the seal body is sealed with an upper cover by the combined action of water pressure and buoyancy. The utility model solves the leakage problem of the automatic pumping water valve in the prior sealing technology, which is safe and water saving.
Description
One, technical field: the utility model relates to the water supply valve door, and particularly a kind of water storage box that is used for is controlled the water supply valve door automatically.
Two, background technique: the existing water autocontrol valve of going up adopts lever principle more, buoyancy by leverage on the seal at water supply valve top, seal is located at the water outlet top of valve body, by the downward applied pressure crush seal of lever body, the water yield in the control.During water, leaking very easily appears this water supply valve in the pressure that needs all the time to overcome water in the valve body on the sealing water outlet.
Three, summary of the invention: the purpose of this utility model is exactly the problem at the easy leakage water of water supply valve existence, and a kind of cistern water level control valve at the valve inner sealing means is provided.
The technical solution of the utility model is: the cistern water level control valve, form by fixing support rack 9, lifting bar 4, active lever 3 and ball float 1 and valve body 8, seal 6 and upper cover body 5 etc.Cavity one side that it is characterized in that valve body 8 is provided with " L " shape honeycomb duct, the bottom of honeycomb duct communicates with water intake, top communicates with the cavity of valve body 8, the seal 6 that can upper and lowerly move freely is housed in the cavity of valve body 8, seal 6 is fixedlyed connected with lifting bar 4, the middle part of the top of lifting bar 4 and active lever 3 flexibly connects, the two ends of active lever 3 are connected with ball float 1 gravity ball 2 with fixing support rack 9 respectively, gravity ball 2 is hollow spheress of upper opening, be provided with circular hole 14 in the middle of the upper cover body 5, be inserted in lifting bar 4, be threaded with the outside thread of valve body 8.This technological scheme further is improved to: the circular hole lower edge in the middle of (1) upper cover body 5 is provided with round boss 13, and with seal 6 crush seals, its upper edge is provided with sets upright boss 12.(2) gravity ball 2 is entity balls, and its weight is not have under the situation of water buoyancy at ball float 1, is enough to offset the pressure of water in the valve body 8.(3) upper surface of seal 6 covers elastic packing colloid 10.
Cistern water level control valve after the employing technique scheme has made full use of the pressure of water in seal process, thoroughly overcome the technical problem that existing water supply valve easily leaks water.
Four, description of drawings:
Accompanying drawing is an overall structure sectional view of the present utility model.
Five, specific embodiment:
As can be seen from the figure, valve body 8 bottoms of cistern water level control valve are provided with screw thread and are threaded with water inlet.Cavity one side of valve body 8 is provided with " L " shape honeycomb duct, and the bottom of honeycomb duct communicates with water intake, and top communicates with the cavity of valve body 8, and the seal 6 that can upper and lowerly move freely is housed in the cavity of valve body 8.Seal 6 is fixedlyed connected by nut 7 with lifting bar 4, and the middle part of the top of lifting bar 4 and active lever 3 flexibly connects.One end and the fixing support rack 9 of active lever 3 connect to form fixed support, and fixing support rack 9 is fixing by the pedestal 11 that is fixed on the valve body 8; The other end is connected with ball float 1, gravity ball 2.Gravity ball 2 is hollow spheress of upper opening, and in the water process, water can inject automatically from its opening, makes the gravity ball be equipped with action of gravity on first.The gravity ball also can directly use an entity ball.In last water process, buoyancy of water acts on the ball float 1, promotes active lever 3, and affect on lifting bar 4 and the seal 6 by lever 3 and to move, after the circular hole 14 in the middle of seal 6 and the upper cover body 5 contact, the pressure of water acted directly on the seal 6 water-stop in the realization at this moment.After drawdown, ball float 1 loss of buoyance effect, gravity ball 2 passes through lever 1 by its gravity and lifting bar 4 promotes seals 6 downwards, and upper cover body 5 and seal 6 are broken away from, and water enters valve body from " L " shape honeycomb duct, by center hole 14 outflows of upper cover body 5.
If the circular hole lower edge in the middle of upper cover body 5 is provided with round boss 13, the upper surface of seal 6 covers elastic packing colloid 10, and elastic packing colloid 10 crush seals with above the seal 6 can increase sealing effect; Its upper edge is provided with sets upright boss 12, can guarantee that lifting bar 4 moves up and down along axis.Gravity ball 2 is after fills with water, or an entity ball, and its weight is not have under the situation of water buoyancy at ball float 1, is enough to offset the pressure of water in the valve body 8.In installing and using process, should adjust the volume and weight of ball float 1 and gravity ball 2 according to the hydraulic pressure situation.
