Abstract
The utility model relates to a floating ball switch, in particular to a floating ball switch applicable to high temperature and high pressure. The floating ball switch comprises a floating ball with a center hollow pipe inside, a switch main body with an inlet/outlet, a switch connecting rod, a sealing member and a buffer member, wherein the switch connecting rod is sleeved in the center hollow pipe and penetrates through a floating ball; the sealing member is fixedly connected with one end of the switch connecting rod; the buffer member is arranged on the floating ball and is located between the surface of the floating ball and the sealing member; and the sealing member is arranged in the switch main body. In the structure, the traditional floating ball and switch connecting rod are changed into a split type, and a buffer member and a spring (or other buffer members) are mounted above and below the control part (control part and sealing member), thus the impact force of the pressure is relieved, and the service life of the product is guaranteed.
Description
Technical field
The utility model relates to a kind of ball float, a kind of more precisely float switch that is applicable to HTHP.
Background technique
Every use ball float is controlled as liquid level, all is the liquid of normal temperature and pressure generally.And use this general ball float in the flow container of HTHP, institute's impact force that forms can be brought damage to float switch when subtracting Push And Release when increasing during pressure, and working life is very short, if in the flow container of HTHP, use, with regard to the frequent replacing of needs.
Summary of the invention
The purpose of the utility model is, provide a kind of simple in structure, the life-span is long, is adapted at the float switch of work under the high temperature and high pressure environment.
The utility model solves the technological scheme that its technical problem adopted: a kind of float switch comprises that inside is provided with the ball float of central hollow tube, is provided with switch main body, switch connecting rod, the Sealing of import and export, is characterized in that also comprising shock absorber; The switch connecting rod is set in the central hollow tube; Run through ball float, Sealing is fixedly connected with an end of switch connecting rod, and shock absorber is arranged on the ball float; Between ball float surface and Sealing, Sealing is arranged in the switch main body.
Further being set to of the utility model: also comprise control piece, spring; Control piece is fixedly connected with the other end of switch connecting rod; Spring is arranged on the ball float, between ball float surface and control piece, is provided with the fluid passage in the switch main body; Passage is the funnel form passage adaptive with Sealing, the switch import, the outlet respectively with channel connection.
Said structure becomes the ball float of traditional type and switch connecting rod split type, and at the upper and lower place at control position (control piece and Sealing) shock absorber and spring (or other shock absorber), the impact force of releasing the pressure, the working life of guaranteeing product is installed.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
Embodiment
Can know that with reference to figure 1 a kind of float switch comprises that inside is provided with the ball float 3 of central hollow tube 5, is provided with switch main body 8, switch connecting rod 4, the Sealing 6 of import and export; Switch connecting rod 4 is set in the central hollow tube 5, runs through ball float 3, and Sealing 6 is fixedly connected with an end of switch connecting rod 4; Shock absorber 21 is arranged on the ball float 3, and between ball float 3 surfaces and Sealing 6, Sealing 6 is arranged in the switch main body 8; Control piece 1 is fixedly connected with the other end of switch connecting rod 4; Spring 2 is arranged on the ball float 3, between ball float 3 surfaces and control piece 1, is provided with the fluid passage in the switch main body 8; Passage is the funnel form passage adaptive with Sealing 6, switch import 7, outlet 9 respectively with channel connection.Wherein shock absorber 21 can be identical parts with spring 2, and shock absorber 21 is set in respectively on the switch connecting rod 4 with spring 2.
Running: under the state of normal pressure, when liquid during completely to half ball float 3, ball float 3 floats the unlatching switch automatically; But in the tank body of pressure was arranged, the buoyancy of its ball float 3 bottoms temporarily was exposed at the gas pressure of first ball float 3 outside the liquid and offsets.Along with liquid continues to increase, shock absorber 21 is pressurized gradually.When liquid all overflows to first ball float 3, the strength of shock absorber 21 in addition, ball float 3 rises switch opens; Also just at this moment; Liquid side is on every side all being born pressure, so the strength when ball float 3 rises is very big, at this moment offsets (perhaps other shock absorber) by the elastic force of spring 2.Switch connecting rod 4 and ball float 3 split activities have changed traditional fixedly welding just, have got rid of the powerful impact force of Push And Release, guarantee that product is durable in use.
When switch is opened, when liquid was expelled to second ball float 3, switch cut out recovery automatically.
