Abstract
The invention relates to a controlled one-way valve, which comprises a valve body provided with a drain port. The controlled one-way valve is characterized in that: a rotatable spindle is horizontally arranged in the valve body; a pressing rod is fixed on the spindle in the valve body; a pressing head at the other end of the pressing rod presses an elastic sealing membrane to closely cover the drain port; and the spindle is also provided with a spring pull rod which is pulled by a spring, so that the spindle drives the pressing rod and the pressing head to press the elastic sealing membrane tightly to achieve the aim of sealing. The elastic sealing membrane is preferably a sealing membrane resistant to oil, acid and alkali or a silicone rubber sealing membrane. The spring pull rod is arranged outside the valve body and is vertical to the spindle; a fixed rod is also arranged outside the valve body; and the spring is connected between the spring pull rod and the fixed rod. A drive handle is arranged on the spindle. Due to the fixed tension of the spring, when the water pressure is greater than the elasticity of the spring, the valve can drain automatically to play a role of balancing the pressure. In addition, the valve is difficult to soil at the sealing position, has long service life, compact structure and reliable action, and cannot generate error action.
Description
Technical field
The invention belongs to a kind of valve, particularly a kind of structure of one-way valve.
Background technique
Existing simple one-way valve all is that a spherical or vertebra shape plug is set in valve chamber usually, and the maximum diameter of this spherical or vertebra shape plug is greater than the water intake diameter, when water intake has certain hydraulic pressure to wash this spherical or vertebra shape plug open, and just can water inlet and outlet; And oppositely, hydraulic pressure makes this spherical or vertebra shape plug block water intake, and water just can not flow, and forms the effect of unidirectional conducting.
What use always in toilet flush is exactly this class one-way valve, it belongs to a kind of falling formula one-way valve: water outlet is located at water tank bottom, ball valve is blocked water outlet during retaining, utilize external force that ball valve is promoted during bath, after water flows out, ball valve falls under action of gravity and blocks water outlet again, prepares retaining.The one-way valve of this structure, it is unreliable to work, and is subjected to the influence that water flows in the water tank very big, is easy to produce the stifled incessantly situation of water outlet, causes water resource waste; Perhaps under the influence of hydraulic pressure, do not flow out how many times with regard to the too early water outlet of blocking, can not finish bath work at water.In addition, excessive when the hydraulic pressure of water tank, when just the water yield was too many, draining maintenance hydraulic pressure, and this class one-way valve automatically also existed structure not compact, shortcomings such as ball valve and the damage of lifting gear ease of connection.
Summary of the invention
The present invention mainly solves the one-way valve of existing one-way valve especially for flush toilet and blow-off line, work unreliable, can not keep hydraulic balance and structure not compact, become easily infected by dirt and cause the technical problem damaged.
One-way valve of the present invention contains valve body, and liquid port is arranged on the valve body, it is characterized in that: laterally be provided with main shaft in valve body, main shaft can rotate, and is fixed with a depression bar on the valve body inner main axis, the pressure head of the depression bar the other end is pushed down an elastic sealing film, and elastic sealing film can be close to and cover liquid port; Also be provided with the spring pull bar on the main shaft, the spring pull bar is held by a spring, and makes main shaft drive depression bar and pressure head tightly push down elastic sealing film, reaches the purpose that seals not water outlet.
Described elastic sealing film can be preferably the upper end and be fixed in valve body, and the lower end freedom is unfixing, and when pressure head lifted, the lower end and the liquid port of elastic sealing film lost sealing, and liquid flows out from the lower end.Elastic sealing film is preferably oil resistant, acidproof, alkaline-resisting sealing film or silicone rubber seal film, is difficult for staiing dirt.
Described main shaft upper spring and spring bracing structure are: the spring pull bar is located at the valve body outside, and the valve body outside also is provided with fixing rod, and spring is connected between spring pull bar and the fixing rod.The angle of further preferred spring pull bar and main shaft is 90 degree, and is just vertical mutually.
Also be fixed with a driving handle on the main shaft, this driving handle applied a power just can drive main axis rotation, make whole valve work.
Controllable check valve of the present invention, but since the deformation behavior of elastic sealing film and the pulling force of spring fix, so excessive when hydraulic pressure, greater than spring force be, just can automatic drain, play the effect of balance pressure.And the difficult dirt that stains of sealing part, long service life, whole valve arrangement compactness, reliable in action can not produce malfunction.
Description of drawings
Fig. 1, the plan view of a kind of structure of the present invention.
Fig. 2, the A-A sectional view of Fig. 1.
Fig. 3, the plan view of Fig. 1.
Among the figure, 1---valve body, 12---liquid port, 2---main shaft, 3---depression bar, 4---pressure head, 5---elastic sealing film, 6---the spring pull bar, 7---fixing rod, 8---spring, 9---driving handle.
Embodiment
According to Fig. 1～3, an embodiment of invention is described.
As Fig. 1 and Fig. 3, present embodiment contains valve body 1, and liquid port 12 is arranged on the valve body 1, pass valve body 1, laterally be provided with the main shaft 2 that can rotate, be fixed with depression bar 3 on the main shaft 2, depression bar 3 the other ends are pressure heads 4, and pressure head 4 is pushed down an elastic sealing film 5, and elastic sealing film 5 covers liquid port.Main shaft 2 is in the outside of valve body 1, and vertical fixing has spring pull bar 6, and valve body 1 is provided with fixing rod 7, between spring pull bar 6 and fixing rod 7, is connected with spring 8.Also be fixed with driving handle 9 on the main shaft 2, driving handle 9 is located at valve body 1 outside also perpendicular to main shaft 2.
Among Fig. 3, the section shape of the form fit valve body 1 of elastic sealing film 5, top is rectangle or circle, and the bottom is circle or rectangle, and its middle and upper part and valve body 1 are fixing.
Usually under the state, under the tension of spring 8, main shaft 2 drives depression bar 3, makes 4 pairs of elastic sealing film 5 of pressure head apply certain power, makes elastic sealing film 5 tightly push down liquid port 12, forms sealing, and flow of liquid is not gone out; When driving handle 9 is applied a power, overcome the pulling force of spring 8, to rotate by main shaft 2, thereby make pressure head 4 be lifted away from elastic sealing film 5, this moment, fluid flowed out by elastic sealing film 5 lower ends.When putting down driving handle,, make elastic sealing film 5 be close to the liquid port place once more and get back to sealing state by the pulling force of spring 8.
Because spring 8 is fixing pulling force, the liquid that seals when elastic sealing film 5 reaches certain pressure, when promptly pressure is greater than pulling force, can realize getting rid of automatically the function of liquid, thereby reach the purpose of pressure limiting.
