Abstract

The utility model relates to a rotproof regulating valve which belongs to the technical field of pump valves. The utility model comprises a valve gate, a valve base, a valve core assembly and an actuating mechanism, a valve core assembly is arranged on the valve base between a fluid inlet and a fluid outlet of the valve gate, and the valve handle in the valve core assembly is linked with the actuating mechanism. The utility model is characterized in that the valve handle in the valve core assembly is coated with a rotproof teflon corrugated pipe; the upper end of the corrugated pipe is connected with a lined fluoroplastic layer at the bottom of the valve core in a face seal mode, and the lower end is connected with a lined fluoroplastic layer in a middle hole of an inner chamber of the valve body in a face seal mode. In this way, the corrugated pipe is compressed and stretched under the action of the actuating mechanism of the regulating valve to enable the valve handle to move up and down. Because conveying media are completely separated by the corrugated pipe, the utility model fundamentally solves the sealing problem of the connecting position of the valve handle, thoroughly prevents medium leakage caused by abrasion because of the friction generated by the longtime motion of the valve handle and fillers of the regulating valve, and ensures the service life of the valve gate and personal safety.

Description

Gas, electronic lined with fluoroplastic sylphon seal modulating valve
Technical field
The utility model relates to a kind of modulating valve, and especially a kind of anticorrosion modulating valve belongs to the pump valve technical field.
Background technique
Modulating valve is one of Self controlling valve commonly used in the industrial process control.Existing modulating valve structure is to be furnished with the spool assembly parts, to be connected actuator by the valve rod in the spool assembly parts and move up and down by the valve seat place between valve fluid is imported and exported, realize between spool, the valve seat unlatching, close and reach the requirement of regulating rate-of flow.For preventing to be in the valve rod of medium from the spool assembly parts under the pipeline pressure state, adopt graphite packing to be sealed usually in the valve rod joint from actuator's joint seepage in the past.Because valve rod and stuffing box packing move up and down friction for a long time, the unavoidable wearing and tearing, so can't fundamentally solve common fault---the medium leakage problems of conventional modulating valve.Especially the strong or poisonous medium of corrosivity, in case seepage will corrode valve body, befouling environment has a strong impact on valve working life, endangers personal safety.
Summary of the invention
The purpose of this utility model is: the gas, the electronic lined with fluoroplastic sylphon seal modulating valve that propose a kind of good sealing effect, do not exist valve rod and filler to wear and tear.
In order to reach above purpose, the utility model gas, electronic lined with fluoroplastic sylphon seal modulating valve comprise valve, valve seat, spool assembly parts, actuator, valve seat place between valve fluid is imported and exported is furnished with the spool assembly parts, valve rod in the spool assembly parts connects actuator, it is characterized in that: the valve stem in the described spool assembly parts is set with corrosion-resistant ptfe plastic bellows outward, the lined with fluoroplastic layer plane of the upper end of described bellows and spool bottom is tightly connected, and the lined with fluoroplastic layer plane of lower end and body cavity mesopore is tightly connected.
Like this, by effect lower compression, the stretching of bellows in modulating valve actuator, guarantee that valve rod is moved up and down, because fed sheet of a media is isolated by bellows fully, therefore fundamentally solved the sealing problem of valve rod joint, thoroughly avoided modulating valve because the wearing and tearing that valve rod and filler move up and down for a long time and rub and produce, and the medium seepage that causes thus, especially the strong or poisonous medium for corrosivity, prevent medium seepage corrosion valve, guaranteed the working life and the personal safety of valve.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Embodiment one
Present embodiment gas, the component part of electronic lined with fluoroplastic sylphon seal modulating valve comprises spool assembly parts 1, valve body lining plastic 2, hexagon nut 3, stud bolt 4, valve body is taken over lining plastic 5, anti-packing 6, support 7, stud bolt 8, hexagon nut 9, screw 10, seal washer 11, filler 12, pressing plate 13, gland 14, double end nut 15, hexagon nut 16, indicator panel 17, hexagon nut 18, the attaching nut 19, pneumatic diaphragn actuating mechanism 20, nut 21, nameplate 22, rivet 23, hex head bolt 24, hexagon nut 25.Between the fluid inlet and outlet of valve body lining plastic 2 spool assembly parts 1 is housed, the upper end of this spool assembly parts 1 is connected with actuator 20 by valve rod and attaching nut 19.In order to overcome valve rod owing to the medium seepage that moves up and down for a long time and wear and tear mutually and produce with filler, to avoid corrosion, suit ptfe plastic bellows outside the valve rod in spool assembly parts 1, the lined with fluoroplastic layer plane of the upper end of this bellows and spool bottom is tightly connected, and the lined with fluoroplastic layer plane of lower end and body cavity mesopore is tightly connected.
Like this, by effect lower compression, the stretching of bellows, guarantee that valve rod is moved up and down in modulating valve actuator.
In addition as seen from Figure 1, the position that valve fluid passes through comprises that body cavity, spool, valve seat, valve rod, valve body connect cover and be lined with fluoroplastics lining, thereby each position of valve and medium is isolated fully, even adopt common iron to make valve body, also can avoid corrosion.
Need to prove that the utility model also is applicable to electric control valve, but the i.e. also electronic lined with fluoroplastic sylphon seal of called after modulating valve.

Claims (3)
