Abstract
The utility model relates to a piston type electric control valve, which is composed of a main valve, an electromagnetic 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 device through a valve rod. The utility model is characterized in that the control device is composed of a piston cylinder and a piston; the utility model has the advantages of reliable operation, 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 suitable for controlling and regulating fluid medium on various pipelines.
Description
The utility model relates to a kind of valve, specifically about a kind of motor-operated control valve.
The motor-operated control valve by electromagnetic valve that uses on the Domestic market mainly is made up of main valve, solenoid valve and connecting tube at present.Its main valve is made of valve body, valve seat, flap, valve rod, valve gap, control mechanism and Sealing and assembling set, and control mechanism is by constituting with the control diaphragm of valve rod interlock and the control chamber of diaphragm upside.Solenoid valve is realized adjusting and control to the main valve switch by the pressure in the control diaphragm upper plenum.Its deficiency is that the diaphragm of main valve control mechanism is in use damaged easily, thereby makes valve function out of hand, and it is unreliable to work, and product is short working life.In addition, in order to prevent medium impurity, filter need be installed at the suction side of main valve to the valve working Effect on Performance.
One of the purpose of this utility model is the problem that exists at prior art, and a kind of reliable operation, long piston type motor-operated control valve of life-span are provided;
Two of the purpose of this utility model is the problems that exist at prior art, and a kind of piston type motor-operated control valve with filter medium impurity function is provided.
The technological scheme that realizes the utility model purpose mainly comprises main valve, solenoid 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, the product that has solved prior art is because of diaphragm breakage, the defective that causes valve function out of hand, its reliable working performance, long service life, and the filter screen that is provided with in its valve body is the impurity in the filter medium effectively, do not need other fixed filter before main valve, simplified the erection unit of pipe-line system, reduce the project installation cost.
Fig. 1 is the structural representation of the utility model piston type electromagnetic valve.
The technical solution of the utility model now is described in further detail in conjunction with the accompanying drawings and embodiments.Piston type electromagnetic valve as shown in Figure 1 mainly is made of main valve, solenoid valve 11 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 9 between valve gap 10 and the valve body 1 and being positioned at the piston 8 of piston cylinder 9 internal fixation in valve rod 5 upper ends.Flap 4 is positioned at the outlet side of valve seat 3, constitutes linking mechanisms with valve rod 5, piston 8, in valve rod 5 peripheries of flap 4 upsides and piston cylinder 9 downsides spring 6 is housed.The suction side passage of valve body 1 and outlet side passage are communicated with by the inner chamber of connecting tube with piston cylinder 9 respectively.
On the connecting tube between valve body 1 suction side passage and the piston cylinder 9 ball valve 12 and filter 13 are housed, filter 13 is installed near valve body 1 side.
On the connecting tube between valve body 1 outlet side passage and the piston cylinder 9 ball valve 7 and solenoid valve 11 are housed.
In the valve body 1 of the suction side of main valve valve seat 3 filter screen 2 is housed.
