Abstract
The utility model relates to a nuclear power membrane valve with a superscript indication. The nuclear power membrane valve with the superscript indication is characterized in that an indication plate is arranged on the top of a valve rod, an indication cover is sleeved on the external of the indication plate, and the indication cover is fixedly connected with the valve rod through a valve rod nut. When the nuclear power membrane valve is used, a hand wheel is rotated, the valve rod nut rotates and drives the valve rod to do linear motion upwards and downwards, the operating direction and the opening degree of the red indication plate at the upper end of the valve rod can be visually observed through the transparent indication cover, meanwhile the closed indication cover protects the head portion of the valve rod, foreign material invasion is avoided, and integrity and attractiveness of the valve are greatly strengthened compared with those of a membrane valve in the prior art.
Description
Technical field
The utility model relates to the pipeline valve apparatus technology, and specifically a kind of nuclear power water system membrane valve that is used for relates in particular to the membrane valve that tape travel is indicated.
Background technique
In the membrane valve structure of the prior art; membrane valve for the Stem Mut structure; there is not special-purpose stroke indicating device; only roughly judge roughly stroke according to the valve rod lifting that exposes; exist during use and can not judge accurately that the aperture of flap and valve rod head do not have dustproof corrosion protection measure, make troubles for the operation of system.
Summary of the invention
The purpose of this utility model is to provide a kind of nuclear power membrane valve of improved band subscript indication, and it can overcome the some shortcomings that valve rod lifting head in the prior art does not have aperture indication and unshielded measure.
To achieve these goals, the technical solution of the utility model is: a kind of nuclear power membrane valve with the subscript indication, it mainly comprises valve body and valve gap, the top of valve gap is provided with valve rod, it is characterized in that: the top of valve rod is provided with indicator board, indicator board is arranged with indication cover outward, fixedlys connected by Stem Mut between described indication cover and the valve rod.
During use; during use; rotate handwheel; the Stem Mut rotation drives valve rod straight line motion up and down, by transparent indication cover; can observe the traffic direction and the aperture of the red indicator board of valve rod upper end very intuitively; Feng Bi indication cover has also been protected the valve rod head simultaneously, avoids foreign object to invade, and the integrity of valve is compared also enhancing greatly with aesthetic property with the membrane valve of existing technology.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Fig. 2 is the structure for amplifying schematic representation of I portion among Fig. 1.
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
Mark is expressed as follows in each accompanying drawing: 1 valve body, 2 barrier films, 3 flaps, 4 valve gaps, 5 handwheels, 6 locking nuts, 7 indicator boards, 8 shaft block rings, 9 indication covers, 10 Stem Muts, 11 thrust-bearings, 12 valve rods, 13 bearing pins.
A kind of nuclear power membrane valve described in the utility model with the subscript indication, it mainly comprises valve body 1 and valve gap 4, the top of valve gap is provided with valve rod 12, its difference with the prior art is: the top of valve rod is provided with indicator board 7, indicator board is arranged with indication cover 9 outward, fixedlys connected by Stem Mut 10 between described indication cover and the valve rod.Described indication cover is that the top is hemispheric transparent cover, and the indication cover is provided with the aperture indication, and described indicator board is red indicator board, and the position that indicator board is provided with is corresponding with the aperture indicating positions on the indication cover.Described indicator board is by shaft block ring and valve rod roof anchorage, and described shaft block ring adopts stainless steel to make.Described Stem Mut top is provided with outside thread, and the bottom of indication cover is hexagonal step, and the step inner chamber is provided with the internal thread that matches with Stem Mut, and described indication cover adopts the high light transmittance acrylic material to make.
In the enforcement, rotation hand wheel 5 drives Stem Mut 10 rotations, and through the trapezoidal thread transmission, valve rod 10 moving linearlies drive flap 3 and barrier film 2 opening/shutting valves.The direction board that is fixed in the valve rod head is with the valve rod moving linearly, and its movement position is corresponding one by one with scale on the transparent indication cover 9.See through indication cover 9, can clearly observe the movement position of red indicator board 7, the unlatching situation that must understand valve directly perceived quantizes reading in real time.
In the implementation process, indication cover 9 adopts the acrylic material (PMMA) of superior performance, and this material has higher transparency, transmittance reaches 92%, and splendid weatherability is arranged, have surface of good hardness and gloss concurrently, satisfy reading of the present utility model and life requirements fully.
In the implementation process, the external foreign matter of valve rod 12 heads is instructed to cover 9 and stops fully, has effectively protected external foreign matter and has entered body cavity inside, causes moment of torsion increase, wearing and tearing to increase and corrosion, has strengthened the completeness of equipment operation greatly.
In the implementation process, indicate the hemispherical nose of cover and the moulding of bottom hexagon step, add the crystal transmission of light of material, strengthened its aesthetic appearance of valve integral body, meet Modern Industry Products elaboration design concept.
