Abstract

This invention relates to container liquid level control structure, which is characterized by the mechanic drive without lever and the body without valve. The structure comprises the floater, flow conductive pipe and soft pipe, wherein the three parts form the channel for inner and outer flow to reflect the floater and terminal valve of liquid level.

Description

The float liquid level valve

(1) technical field: the float liquid level valve that the present invention relates to liquid level in a kind of automatic control container

(2) background technology: liquid level control is the necessary technology of a lot of industries in the container, and existing level controling mechanism is comparatively complicated, generally form by float, water inlet pipe, leverage and valve head etc., and complex structure, the cost height also is easy to generate fault simultaneously.

(3) summary of the invention: the present invention will provide a kind of simple in structure, and cost is low, easily makes level controling mechanism in the service-strong container.

The present invention is achieved in that single floating body has triple functions; Float, fluid flowing passage, and stop valve effect, in floating body, be equipped with first-class body canal, its lower end links to each other with the import or export of container with flexible pipe, its flexible material in port, upper end constitutes the mouth of pipe of fluid conduit systems, it is that fluid inlet from container is through flexible pipe that extraneous fluid enters container, floating body and fluid conduit systems, flow into the container from the mouth of pipe, when liquid level rising floating body also increases under buoyancy, when the liquid level in the container reaches the position of setting, also be that floating body is raised to certain position, the mouth of pipe and vessel top inwall are fitted, cut off fluid automatically and continue to flow into.

For the container that the overflow requirement is arranged, then have an aperture on floating body top, for liquid level surpasses setting height, liquid orifice flow is from childhood gone in the floating body, the float lower end is provided with an overflow pipe joint, also links to each other with the gap of container with flexible pipe, and excess liquid flows to the external world from gap, do not have this needs for some container, then can cancel this part structure.

Compared with prior art, its technique effect is as follows: structure is obviously simplified, and cost descends, and reliability improves, and can reach zero failure substantially.

(4) description of drawings: accompanying drawing proposes the structure composition diagram of " float liquid level valve " according to the present invention.

(5) embodiment: below in conjunction with description of drawings ins and outs of the present invention and working condition.

The present invention is a kind of no mechanical transmission, the level controling mechanism of valveless entity, and wherein, though the valveless entity has the function of valve, the valve function is such enforcement.The interior hollow of floating body (1), for remaining the state of top-uping, can make right cylinder or square body, the fluid conduit systems (2) that floating body (1) central configuration one rigid material is made, fluid conduit systems (2) upper end is equipped with the mouth of pipe (3) that a flexible material is made, fluid conduit systems (2) can be made into adjustable type and fixed as required, stationary structure is simple, just a straight tube is fixed in the floating body (1), for adjustable type, then protrude a threaded body (5) in floating body (1) central upper, wherein be provided with plasticity bedding and padding (7), and by one the pipe bolt (6) match, when the liquid level in the needs adjusting container, as long as unclamp pipe spiral shell inspection (6) earlier, or on, or following fluid conduit systems (2) position that changes as required, and then screw bolt, compressing bedding and padding (7), make it distortion, fluid conduit systems (2) pinning, fluid conduit systems (2) lower end is connected with flexible pipe (4), flexible pipe (4) other end is connected with the fluid inlet (11) of container, when container rises to desired location, floating body (1) also rises under buoyancy thereupon, the mouth of pipe (3) is fitted with the top inwall of container, the fluid admittance is blocked, ending fluid enters in the container, for the mouth of pipe (3) and the top inwall of container are fitted good, fluid conduit systems (2) must keep the upright position with floating body (1), the top inwall of container is vertical with fluid conduit systems (2), if fluid conduit systems (2) can not be vertical with the top inwall of container, then should set up vertical with it projection, for the occasion of need overflow, as long as bore an aperture (8) in floating body (1) upper side, the bottom is connected with an overflow hose (10), overflow hose (10) other end is connected on the overflow outlet (12) of container and locates, in container, when liquid level rose too high, liquid can be in hole (8) flow into floating body (1) chamber, through overflow hose (10), flow to the external world from overflow outlet (12).

Claims

1. the float liquid level valve of control liquid level automatically in the liquid container, its special card is:

This float liquid level valve comprises floating body (1), be configured in the fluid conduit systems (2) and the mouth of pipe (3) of floating body central authorities, described float liquid level valve constitutes the entity structure of a no lever machinery transmission and valveless, flexible pipe (4) one ends are connected the lower end of fluid conduit systems (2), the other end of flexible pipe (4) then is connected on the fluid inlet (11) of container, under buoyancy, floating body (1) fluctuates, make the mouth of pipe (3) and vessel top inwall or place projection on the vessel top inwall, fit or disengagement, the technical scheme of cutout of control fluid or topping up realizes controlling automatically the valve function of fluid level in the container.

2. float liquid level valve according to claim 1; It is characterized in that described floating body (1) is hollow and construction profile should be made Cylinder, square body, in liquid level, be in the state of top-uping to keep floating body (1).
