Abstract

The utility model discloses a hand wheel valve, it includes valve body, diaphragm and hand wheel executor, the hand wheel executor is including locking parts, hand wheel, adjustable ring, valve shaft, plastics ring sum valve gap, the adjustable ring with plastics rings set up in the outside of valve shaft, the adjustable ring with the valve shaft passes through threaded connection, the locking parts pass the hand wheel with the adjustable ring with the valve shaft is connected. The utility model discloses be different from traditional hand wheel and valve shaft fixed connection's method, not only the design is compact, and simple structure is applicable to the valve of different latus rectums, the effectual life who lengthens the diaphragm, and the axial motion who has utilized the relative hand wheel of valve shaft shows the state of opening and shutting of valve in addition ingeniously, and the valve position observes convenient directly perceived, and installation, operation are convenient.

Description

Hand wheel valve

Technical field

This utility model relates to a kind of hand wheel valve.

Background technology

Using handwheel as the valve of hand actuator be at a kind of valve common in modern industry. The rotation of handwheel when not by external tool, can be realized the folding to valve by manpower by this type of valve.

When hand wheel valve conventional at present there is problems of closing valve, in order to ensure completely closing, sealing and excessive compression diaphragm, make shorten the service life of diaphragm; This also grasps the folding condition of valve to operator simultaneously and brings inconvenience.

Utility model content

The technical problems to be solved in the utility model is the defect making its lost of life in order to overcome prior art excessively to install diaphragm, it is provided that the hand wheel valve of a kind of adjustable limit position.

This utility model solves above-mentioned technical problem by following technical proposals:

A kind of hand wheel valve, it includes valve body, diaphragm and handwheel executor; Described handwheel executor includes locking parts, handwheel, adjustment ring, valve shaft, plastic hoop and valve gap, described adjustment ring and described plastic hoop are arranged at the outside of described valve shaft, described adjustment ring and described valve shaft are threaded connection, to prevent from regulating ring and valve shaft generation slip phenomenon, and making the rotation regulating ring can be converted into the axially-movable of valve shaft, described locking parts are connected through described handwheel and described adjustment ring with described valve shaft.

It is preferred that described valve gap is connected with described diaphragm and is fixed on the bottom of described valve shaft, to protect diaphragm and valve shaft.

It is preferred that the bottom of described locking parts is provided with a screw rod, the top of described valve shaft is correspondingly provided with a screwed hole, better to fix handwheel.

It is preferred that the upper end of described valve shaft is a square shaft, the middle part of described handwheel is correspondingly provided with a rectangular opening, it is prevented that is provided without between handwheel and the valve shaft that traditional approach is fixing and produces to slip, strengthens both annexations.

In this utility model, above-mentioned optimum condition meet on the basis of this area general knowledge can combination in any, obtain each preferred embodiment of the present utility model.

Positive progressive effect of the present utility model is in that: this utility model is different from tradition handwheel and fixes the method being connected with valve shaft, not only compact to design, simple in construction, it is applicable to the valve of different latus rectum, effectively extend the service life of diaphragm, and make use of the axially-movable of the relative handwheel of valve shaft to show the folding condition of valve dexterously, the observation of valve position is convenient directly perceived, installs, operation facility.

Fig. 1 is the structural representation of this utility model preferred embodiment.

The axle that Fig. 2 is this utility model preferred embodiment surveys assembling schematic diagram.

Detailed description of the invention

This utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

As it is shown in figure 1, a kind of hand wheel valve, it includes valve body 1, diaphragm 2 and handwheel executor 3; As shown in Figure 2, described handwheel executor includes locking parts 4, handwheel 5, regulates ring 6, valve shaft 7, plastic hoop 8 and valve gap 9, described adjustment ring 6 and described plastic hoop 8 are arranged at the outside of described valve shaft 7, described locking parts 4 are connected through described handwheel 5 and described adjustment ring 6 with described valve shaft 7, and described valve gap 9 and described diaphragm 2 are fastened on the bottom of described valve shaft 7. Described adjustment ring 6 is threaded connection with described valve shaft 7. The bottom of described locking parts 4 is provided with a screw rod, and the top of described valve shaft 7 is correspondingly provided with a screwed hole. The upper end of described valve shaft 7 is a square shaft, and the middle part of described handwheel 5 is correspondingly provided with a rectangular opening.

In handwheel executor, the folding of valve be by the briquetting in valve gap 9 lift up and under press, drive the diaphragm 2 under it to realize. Valve gap 9 plays protection handwheel executor's internal structure and the effect being connected with valve body 1.

When mounted, first take off being used for the handwheel 5 locking parts 4 with valve shaft 7, after handwheel 5 and adjustment ring 6 are taken off, handwheel 5 reversing is enclosed within the axle side of valve shaft 7. Under aeration status, rotation hand wheel 5, by valve closing, just gastight time, takes off handwheel 5, is enclosed within valve shaft 7 by adjustment ring 6 and down rotates covers plastic hoop 8. Now valve is in the state just closed. Handwheel 5 is enclosed within axle side with normal mounting direction again, locking parts 4 is connected with the screwed hole at valve shaft 7 top, is used for fixing handwheel 5. Now handwheel 5 can only rotate toward opening valve direction, closes direction and has been conditioned ring 6 and limits, thus not resulting in excessive power extruding diaphragm 2.

In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.

Although the foregoing describing detailed description of the invention of the present utility model, it will be appreciated by those of skill in the art that these are merely illustrative of, protection domain of the present utility model is defined by the appended claims. Those skilled in the art is under the premise without departing substantially from principle of the present utility model and essence, it is possible to these embodiments are made various changes or modifications, but these change and amendment each falls within protection domain of the present utility model.
