Abstract
The utility model provides a valve sequence switch control mechanism which comprises a first valve and a second valve. A first control disk is arranged on a valve rod of the first valve. A second control disk is arranged on a valve rod of the second valve. Outer edges of a first disk face and a second disk face are both in a circular arc shape. A first notch is arranged on the first disk face. A second notch is arranged on the second disk face. The first notch and the second notch are both in a circular arc shape. When the two valves are both opened, the first disk face is meshed with the second notch, and only when the first valve is opened first can the second valve be opened; and when the two valves are both closed, the second disk face is meshed with the first notch, and only when the second valve is closed first can the first valve be closed. Therefore, opening and closing operation of the two valves only according to a specific sequence is ensured, and therefore misoperation behaviors of the opening and the closing of the valves not according to the sequence is prevented, and the possibility of occurrence of accidents is reduced.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of valve sequence switch control mechanism.
Background technique
Class valves such as ball valve, stopcock and butterfly valve generally all are to realize the unlatching of valve or close through 90 ° of rotary manipulations of handle or handwheel.In some commercial plant, the switch of two deck valve doors must in case switching sequence makes a mistake, can cause great accident according to specific order.Usually carry out the autocontrol valve that valve switch is operated and controlled for Electric actuator or Pneumatic actuator; Can guarantee the switching sequence of valve through the setting of control program; But for adopting handle or handwheel to carry out manually-operated valve; Also there is not the mechanism that the valve switch order is controlled in the existing technology, therefore might causes the mistake of valve switch order, thereby have an accident because of misoperation.
The model utility content
The utility model is to the deficiency of above-mentioned existing technology, and a kind of valve sequence switch control mechanism that can the limiter valve switching sequence is provided.
The utility model is realized through following technological scheme:
A kind of valve sequence switch control mechanism; Comprise first valve and second valve, it is characterized in that the valve rod of first valve is provided with first control panel; First control panel comprises the interconnective first handle and first card, and first handle is used to drive first card and rotates;
The valve rod of second valve is provided with second control panel, and second control panel comprises the interconnective second handle and second card, and second handle is used to drive second card and rotates;
It is circular-arc that the outer rim of first card and second card all is, and first card is provided with first breach, and second card is provided with second breach; First breach and second breach all are circular-arc; First breach is identical with the curvature of second card, and second breach is identical with the curvature of first card;
When first valve and second valve are all opened, first card and the engagement of second breach; When first valve and second valve are all closed, second card and the engagement of first breach.
Further, first valve and second valve can be installed in respectively on two adjacent pipelines; Also can be installed on the same pipeline, and adjacent setting.
The described valve sequence switch of the utility model control mechanism, through offering breach in the outer rim of first card and second card, and the size of appropriate design card and breach is guaranteed the cooperation contact between the control panel of two valves.When two valves are all opened, the engagement of first card and second breach, have only first valve to open earlier after, second valve could be opened; When two valves are all closed, the engagement of second card and first breach, have only second valve to close earlier after, first valve just can be closed; Guaranteed that so two valves can only carry out the keying operation of valve according to specific order, thereby prevented generation, reduced the possibility that accident takes place not according to the misoperation behavior of this order open and close valve.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Present embodiment is installed in respectively on adjacent the pipeline A and pipeline B with first valve and second valve, and it is closed position that valve handle is in the direction vertical with pipeline, and the valve handle half-twist can be realized opening or the situation of throttle down is that example describes.Shown in Fig. 1-4; The utility model provides a kind of valve sequence switch control mechanism; The valve rod that comprises first valve 1 and second valve, 2, the first valves 1 is provided with first control panel, and first control panel comprises the interconnective first handle 4 and first card 3; First handle 4 is used to drive first card 3 and rotates around its card center, to realize the opening and closing of valve.The valve rod of second valve 2 is provided with second control panel, and second control panel comprises the interconnective second handle 5 and second card 6, and second handle 5 is used to drive second card 6 and rotates around its card center; To realize the opening and closing of valve.The outer rim of first card 3 and second card 6 all is circular-arc, and first card 3 is provided with first breach, 7, the second cards 6 and is provided with second breach 8; First breach 7 and second breach 8 all are circular-arc; First breach 7 is identical with the curvature of second card 6, and second breach 8 is identical with the curvature of first card 3.First breach 7 is positioned at the side of first card 3 in the present embodiment; Second breach 8 is positioned at the top of second card 6; Angle between the center line of the center line of first breach 7 and first card 3 is 90 degree, the central lines of the center line of second breach 8 and second card 6.First valve 1 described in the utility model and second valve 2 can be not limited to certain specific valve for valve classes such as ball valve, stopcock or butterfly valves.
The working procedure of the said valve sequence switch of the utility model control mechanism is following:
As shown in Figure 2, when first valve 1 and second valve 2 were all in the closed position, pipeline A goes up first valve 1 in the closed position can be through operation first handle 4 normal Open valves counterclockwise; And be in second valve 2 of closed condition on the pipeline B owing to receive the restriction of last first card 3 of pipeline A, and can't carry out the operation of Open valve.Promptly when first valve 1 and second valve 2 are all closed, can only pacify according to opening first valve 1 earlier, the sequential operation of second valve 2 is opened in the back.
As shown in Figure 3, when first valve 1 on the pipeline A was in the enable possition, because this moment, first card 3 did not have restriction for second valve 2, at this moment, second valve 2 on the pipeline B was free to carry out the opening and closing operation.
As shown in Figure 4, when first valve 1 and second valve 2 all were in the enable possition, first card 3 was owing to receive the restriction of second card 6, and this moment, first valve 1 can't carry out closing operation; Have only after second valve 2 on the pipeline B is closed, first valve 1 just can carry out closing operation.Promptly when first valve 1 and second valve 2 are all opened, can only be according to closing second valve 2 earlier, after close the sequential operation of first valve 1.
The utility model not only is confined to above-mentioned embodiment; Persons skilled in the art are according to the disclosed content of the utility model; Can adopt other multiple embodiment to implement the utility model, therefore, project organization of every employing the utility model and thinking; Do some simple designs that change or change, all fall into the scope of the utility model protection.
