Description
Technical field
This utility model relates to valve technology field, is specifically related to a kind of anti-grinding and hinders sandwich valve。
Background technology
Valve (famen) is the control parts in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief。For the valve of fluid control systems, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are quite various。Valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium。Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve (201,304,316 etc.), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized waits valve material。Wherein, sandwich valve is the special valve for blocking operation on pipeline, is arranged in the closure threeway on pressure line, is used for taking up tapping machine and carries out press and open holes, uses plugging device closure pressure line, completes the operations such as the repairing of pipeline, construction。Also in pigging operation, the medium stream in a certain pipeline section region can be intercepted or dredged。
All movements within existing sandwich valve are all hard contacts, long-term hard contact, it is easy to cause that moving component weares and teares when motion, cause the failure of operation, it would be highly desirable to improve。
Summary of the invention
The purpose of this utility model is in that the defect for prior art and deficiency, it is provided that a kind of simple in construction, anti-grinding reasonable in design, easy to use hinder sandwich valve, it is possible to alleviating the wear phenomenon that rigid contact causes, improve work efficiency, practicality is higher。
For achieving the above object, the technical solution adopted in the utility model is: it comprises upper valve body, lower valve body, center valve body, clamping plate, screw mandrel sealing member；Being provided with center valve body between upper valve body and lower valve body, be provided with clamping plate in center valve body, the side of center valve body is provided with screw mandrel sealing member；Described screw mandrel sealing member is rubber thread shaft seal；The upper and lower both sides of described clamping plate are equipped with several copper coins。
Described copper coin is fixedly connected on clamping plate by screw, and the quantity of copper coin carries out as required increasing and reduces。
Operation principle of the present utility model: due to the setting of copper coin, clamping plate are when motion, contact between copper coin with upper valve body and lower valve body, avoid clamping plate directly to contact with upper valve body and lower valve body, adopt rubber seal between screw mandrel and center valve body simultaneously, avoid rigid contact, decrease wear phenomenon, improve work efficiency。
After adopting said structure, this utility model has the beneficial effect that anti-the grinding of one described in the utility model hinders sandwich valve, it is possible to alleviates the wear phenomenon that rigid contact causes, improves work efficiency, practicality is higher, and has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low。
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。
Fig. 1 is structural representation of the present utility model。
Fig. 2 is side view of the present utility model。
Description of reference numerals:
1, upper valve body；2, lower valve body；3, center valve body；4, clamping plate；5, screw mandrel sealing member；6, copper coin。
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described。
Referring to shown in Fig. 1 and Fig. 2, this detailed description of the invention the technical scheme is that it comprises upper valve body 1, lower valve body 2, center valve body 3, clamping plate 4, screw mandrel sealing member 5；Being provided with center valve body 3 between upper valve body 1 and lower valve body 2, be provided with clamping plate 4 in center valve body 3, the side of center valve body 3 is provided with screw mandrel sealing member 5；Described screw mandrel sealing member 5 is rubber thread shaft seal；The upper and lower both sides of described clamping plate 4 are equipped with several copper coins 6。
Described copper coin 6 is fixedly connected on clamping plate 4 by screw, and the quantity of copper coin 6 carries out as required increasing and reduces。
The operation principle of this detailed description of the invention: due to the setting of copper coin 6, clamping plate 4 are when motion, contact between copper coin 6 with upper valve body 1 and lower valve body 2, avoid clamping plate 4 to contact with upper valve body 1 and the direct of lower valve body 2, adopt rubber seal between screw mandrel and center valve body 3 simultaneously, avoid rigid contact, decrease wear phenomenon, improve work efficiency。
After adopting said structure, this detailed description of the invention has the beneficial effect that a kind of high efficiency sandwich valve described in this detailed description of the invention, it is possible to alleviates the wear phenomenon that rigid contact causes, improves work efficiency, practicality is higher, and has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low。
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that the technical solution of the utility model is made by those of ordinary skill in the art or equivalent replace, without departing from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model。
