Abstract
The utility model provides a liquid level control valve which comprises a spherical valve core, a front valve body, a rear valve body and sealant. Sealant is filled in inner cavities of the front body and the rear valve body; a spherical valve core is arranged in the inner cavity of the sealant; a through hole and a floating ball connecting hole with threads are arranged in the center of the spherical valve core, and the floating ball connecting hole is connected with a floating ball connecting rod. The spherical valve core is provided with the floating ball connecting hole with the internal threads, the floating ball connecting hole can be in threaded connection with a common floating ball connecting rod, the liquid level control valve adopts the spherical valve core and the sealant, therefore, the liquid level control valve can utilize the spherical sealing function of the spherical valve core and the sealant to overcome the technical problem of poor sealing property of the existing liquid level control valve. The liquid level control valve has the advantages of good sealing property, simple structure, long service life and low cost.
Description
Technical field:
The utility model relates to the fluid level control valve that a kind of full position of liquid level that is applied to various liquid is controlled automatically, utilizes the sphere contact seal of spherical valve core and sealer, does not use accessory power supply, and is simple in structure, good airproof performance.
Background technique:
At present, the mechanical type liquid levels of use, liquid level control fluid level control valve adopt the lever construction principle, utilize buoyancy of liquid to act on a valve end of lever, connect sealed briquette in the middle of the lever, briquetting overlayed the mouth of pipe automatically when liquid level rose, and realized the sealing of the liquid mouth of pipe.In order to guarantee sealability, the softer material of the most uses of sealer, the sealer and the mouth of pipe were easy to generate skew when ball float swung in the using process, the impression of sealer often changes makes that sealer weares and teares, deformed damaged, cause poor sealing, liquid level exceeds the liquid level of requirement control, the liquid container that can overfill.
Summary of the invention:
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of liquid level control ball valve, comprises spherical valve core, front valve shell, rear valve body, sealer.Body cavity has sealer, the sealer inner chamber has spherical valve core, spherical valve core has through hole and tapped ball float attachment hole is arranged, described ball float attachment hole can be connected with the Thread valve of the connecting rod of common ball float, described front valve shell is provided with opening slot, the connecting rod of ball float passes described opening slot and links to each other with the ball float attachment hole, described fluid level control valve design has spherical valve core and sealer, described fluid level control valve to utilize the ball face sealing function of spherical valve core and sealer to overcome the technical problem of the sealing difference of existing fluid level control valve.
Technical solution of the present utility model is such: comprise spherical valve core, front valve shell, rear valve body, preceding sealer, back sealer, ball float attachment hole, opening slot.It is characterized in that front valve shell and rear valve body are to be threaded, the front valve shell inner chamber has first sealer, rear valve body inner chamber that second sealer is arranged, first sealer, second sealer inner chamber dress spherical valve core, spherical valve core center have through hole, the ball float attachment hole are arranged, rear valve body and second sealer are sphere contact seal.
The sealing surface of first sealer, second sealer is a sphere.
Front valve shell is provided with opening slot.
The ball float attachment hole of spherical valve core is connected with ball float and tightens up.
Advantage of the present utility model is that described body cavity has sealer, the sealer inner chamber has spherical valve core, spherical valve core has tapped ball float attachment hole to be connected with common ball float, fluid level control valve utilizes the ball face sealing function of spherical valve core and sealer, overcomes the technical problem of the sealing difference of existing fluid level control valve.The utlity model has good airproof performance, simple in structure, long service life, advantage that cost is low.

Embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing, front valve shell (1) is connected with rear valve body (4) axial screw thread, front valve shell (1) inner chamber is equipped with first sealer (2), rear valve body (4) is equipped with second sealer (5), first sealer (2), second sealer (5) inner chamber are equipped with spherical valve core (3), and spherical valve core (3) has tapped ball float attachment hole (6).Front valve shell (1) has opening slot (7), and the interface tube of rear valve body (4) has pipe thread.Spherical valve core (3) is spherical, and first sealer (2), second sealer (5) are spherical shape with spherical valve core (3) surface of contact.Ball float attachment hole (6) on the spherical valve core (3) is an internal thread.The spherical surface of contact of spherical valve core (3) and first sealer (2), second sealer (5) is a sealing surface, and its good seal performance can solve the problem of common fluid level control valve sealing difference.Spherical valve core (3) has the ball float attachment hole (6) of band inner bolt hole, is used to connect the connecting rod of stand-by common ball float.Front valve shell (1) is established opening slot (7); its role is to install the connecting rod of stand-by common ball float; and control the rotation amplitude of spool by the pendulum angle of connecting rod of restriction ball float, ball float was opened spool because of the deadweight tenesmus thereby drive valve core rotation by connecting rod when liquid level was low; float on liquid level when liquid level is high on the ball float; drive valve core rotation by connecting rod, thereby close spool, when the ball float connecting rod is up run into the opening slot end face; can't more up play the position limitation protection effect.Described rear valve body has the pipe thread, conveniently is connected with other pipelines.
