Abstract

The invention discloses a multi-position slide plate-type valve operating system. When a handle is forced towards one side, the lower end of the handle enters the groove of a slide plate at the other side to unlock the slide plate and simultaneously drives the slide plate to move forwards and backwards to push one of valve steel balls to the working position. When the handle returns to the intermediate position, linked locks at two sides completely lock the slide plate. The above-mentioned operation is repeated in each working position, one working position at each time. In one embodiment, the operations in four working positions are respectively completed by one handle, thereby realizing single-handle operation and interlocking of the working positions and ensuring one operation in one working position. Three icons of lifting, rapid dropping and slow dropping are provided as operational indicators, to facilitate users of any countries and the illiterate, avoid misoperation, and improve operational convenience and safety.

Description

Multi-station skateboard type air valve operating system

Technical field

The present invention relates to a kind of multi-station skateboard type air valve operating system, belong to field operation in the compressed air control system, when the controlled device demand reaches three working positions or more for a long time, can synthesize a valve, monolever is finished, easy and simple to handle reliable, play the effect that prevents misoperation.

Background technique

The gas control operating technology is very long in world's development and application history, though kind is many, but the person has only two working positions at most, when having three above working positions to require, all be to finish by two valves and dress or two handles or more handles, the equipment handle that has reaches dozens of, handle is many just to enter two working positions easily simultaneously, the operation indication is also just Chinese or English, do not have the pictograph icon, very easily cause misoperation, often have an accident, because of the many inevitable volumes of handle are bigger, use with installation very inconvenient.

Summary of the invention

The objective of the invention is to exploitation and provide a kind of different with conventional construction, multi-station skateboard type air valve operating system, accomplish when three above demands of working position are arranged, the monolever operation, each working position reciprocal interlocking, each action can only be operated a working position, the pictograph icon is established in the operation indication, make things convenient for each languages personnel and illiteracy to use, stop misoperation, improve convenience and the Safety performance used.

The object of the present invention is achieved like this:

Multi-station skateboard type air valve operating system provided by the invention, the dump truck that requires with four working positions is an example: handle middle part design one and half garden balls, placing top is in the hemispheric valve gap, and valve gap top viewing surface is established and is respectively lifting, falls soon, overflows and fall three kinds of operation indication icons; Can be designated that A lifts, A falls, A overflows and falls, B lifts, B falls or 1 lift, 2 lift, 3 lift, 4 multiple signals sign such as lift.The basic square slide plate storehouse that is is established in the bottom, and interlock lock tube and spring housing are established in both sides, slide plate storehouse; Establish two slide plates about dividing in the storehouse, elongate recesses is established at the slide plate middle part, and two side lower parts are platform; Two of conventional appearances are pressed valve balls in groove, and each slide plate can be done and seesaw, and because of being platform before and after the slide plate bottom, it is voltage-controlled to press valve balls carry out to two respectively, and two slide plates are four working positions of may command; Two and the half garden grooves opposite with the lower recess direction are arranged at slide plate top, and linkage lock is established in the groove outside, moves in two grooves to satisfy operating grip, controls two slide plates respectively, and the linkage lock of compression slide plate both sides, and operation system places more than the valve body plane.Pictograph icon indication image understands that many working positions are the monolever operation, and handle can only be controlled a working position at every turn, interlocks between each working position, accomplishes easy-to-operat and stops error in operation.

Described multi-station skateboard type air valve operating system is made up of ten several parts, as Fig. 7 sign promptly 1, handle, 2, handle half garden ball, 3, spherical valve gap, 4, the handle return spring, 5, left and right sides slide plate, 6, interlocking inner push-rod, 7 interlocking lock tubes, 8, interlocking spring, 9, the spring shrouding, 10, air valve upper surface plate, 11, press the valve steel ball; Promote a sideskid and release on one side as identification number 12 handles, 13, one of them presses valve steel ball to enter working position, 14, one sideskid on the working position, 15, slide plate is pressed into the working position state with steel ball.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Embodiment

Shown in Fig. 1,2,3 assembly relations and Fig. 4,5,6 pictographs sign: multi-station skateboard type air valve operating system handle 1 as shown in Figure 7 and half garden ball are bonded together and pack in the center hole of spherical valve gap 3, reinstall handle return spring 4, reinstall left and right sides slide plate 5, push interlocking inner push-rod 6 according to the order of sequence from the outer hand hay cutter of valve seat, interlocking lock tube 7, interlocking spring 8 refills upper spring shrouding 9, again that air valve upper surface plate 10 and valve gap 3 is bonding, reinstall and press valve steel ball 13.

As previously mentioned: as shown in Figure 7, handle is to a side reinforcing, handle, at its lower end enters also release on one side in the opposite side slider groove, driving slide plate simultaneously does and seesaws, press the valve steel ball to be pressed into the working position one of them, shown in the sign 14 of Fig. 8, a sideskid is on the working position, and slide plate is pressed into the working position state with steel ball 15.Get back to the neutral position as Fig. 1 handle, the both sides linkage lock is with the whole lockings of slide plate; So each working position of operation can only enter a working position at every turn, and as this example: a handle can be finished four working positions respectively, has finished monolever operation of the present invention, each working position reciprocal interlocking, each action and can only operate a working position; Operating indication as Fig. 9 establishes lifting, falls, falls slowly three kinds of pictograph icons soon, makes things convenient for each languages personnel and illiteracy to use, stops misoperation, reaches the convenience of raising use and the purpose of Security.
