Abstract
The utility model relates to a piston type remote controlled float ball valve, which is composed of a main valve, a control float valve and a connecting pipe, wherein, a valve clack of the main valve is positioned on the outlet side of a valve seat and is interlocked with a control mechanism through a valve rod. The utility model is characterized in that the control mechanism is composed of a piston and a piston cylinder; thereby, the utility model has the advantages of reliable performance, long lifetime, etc. A filter screen is arranged in a valve body of the inlet side of the valve seat of the main valve, without an outer filter; the utility model is very suitable for the automatic control for the liquid level of a container on an infusion pipeline with a large caliber.
Description
The utility model relates to a kind of valve, specifically about a kind of float valve.
Float valve is to utilize the liquid level of liquid medium to control a kind of valve of its on off state automatically, and it is simple in structure, cost is low.But on heavy-caliber pipeline, ball float drives valve opening and closing needs bigger buoyancy, causes valve working malfunctioning easily.
China's utility model patent number is 98214954.9, the float valve of notification number CN2347021Y, adopt a main valve and the control float valve composition that the control main valve opens and closes, by the pressure in the main valve diaphragm chamber on the small-bore float valve control heavy-caliber pipeline, realization is to the control of main valve on off state, its reliable operation, flexibly.But its deficiency is that the diaphragm of main valve is in use damaged easily, in case diaphragm breakage leaks, main valve is with function out of hand, and its working life is short.In addition, for preventing the service behaviour of medium impurity effect valve, generally also to filter be installed at the suction side of main valve.
One of the purpose of this utility model is the deficiency that exists at prior art, and a kind of reliable performance is provided, the piston type remote control float valve that the life-span is long;
Two of the purpose of this utility model is the deficiencies that exist at prior art, and a kind of piston type remote control float valve with filter medium impurity function is provided.
The technological scheme that realizes the utility model purpose mainly comprises main valve, control float valve and connecting tube, and the flap of main valve is positioned at the outlet side of its valve seat, and by valve rod and control mechanism interlock.Control mechanism is made of piston cylinder and piston, in the valve body of main valve valve seat suction side filter screen is housed.
The utility model beneficial effect compared with prior art is that the control mechanism of main valve is made of piston and piston cylinder, solved existing product makes valve function out of hand because of diaphragm breakage defective, product performance are reliable, the life-span is long, and the impurity in the filter screen that is provided with in the valve body energy filter medium is to the influence of valve performance, do not need other fixed filter on the pipeline before valve, simplify the erection unit of pipe-line system, reduce system's installation cost.
Fig. 1 is the structural representation of the utility model piston type remote control float valve.
The technical solution of the utility model now is described in further detail in conjunction with the accompanying drawings and embodiments.Piston type remote control float valve as shown in Figure 1 is made up of main valve, control float valve 9 and connecting tube.Main valve comprises valve body 1, valve seat 3, flap 4, valve rod 5, valve gap 10, spring 6, control mechanism and assembling set and Sealing.Control mechanism constitutes by being contained in the piston cylinder 7 between valve gap 10 and the valve body 1 and being positioned at the piston 8 of piston cylinder 7 internal fixation in valve rod 5 upper ends.Flap 4 is positioned at valve seat 3 outlet sides, constitutes linking mechanisms with valve rod 5, piston 8, in valve rod 5 peripheries of flap 4 upsides and piston cylinder 7 downsides spring 6 is housed.The suction side of valve body 1 is communicated with piston cylinder 7 inner chambers by connecting tube, and the inner chamber of piston cylinder 7 is communicated with by the suction side of connecting tube with control float valve 9.
On the connecting tube between valve body 1 suction side passage and the piston cylinder 7 needle value 11, ball valve 12 and filter 13 are housed, filter 13 is installed near valve body 1 side.
Be provided with filter screen 2 in the valve body 1 of the suction side of main valve valve seat 3.
Claims (2)
1, a kind of piston type remote control float valve, mainly comprise main valve, control float valve (9) and connecting tube, the flap of main valve (4) is positioned at valve seat (3) outlet side, and by valve rod (5) and control mechanism interlock, it is characterized in that: described control mechanism is made of piston (8) and piston cylinder (7); Be provided with filter screen (2) in the valve body (1) of valve seat (3) suction side.
2, piston type remote control float valve according to claim 1 is characterized in that on the connecting tube between valve body (1) suction side passage and the piston cylinder (7) filter (13) being housed.
