Abstract

The invention relates to a sealing valve, comprising a valve body, a valve core, a valve rod and a hand wheel, wherein the valve core is connected with the valve rod, the valve rod is connected with the hand wheel, the valve core and the valve rod are positioned inside the valve body, the valve body is provided with an entrance and an exit, the valve core comprises a pressing block connected with the valve rod, cover bodies are arranged on the entrance and the exit inside the valve body, the top end of each cover body is provided with a rotating shaft which is connected with the valve body, the two sides of the cover bodies are provided with a first rotary connecting rod respectively, the bottom of the valve body is rotationally provided with V-shaped levers, one ends of the V-shaped levers are rotationally connected with the first rotary connecting rods, and the other ends of the V-shaped levers are rotationally connected with the pressing block through second rotary connecting rods. After the above structure is adopted, rotation cannot occur when the sealing valve is opened and closed due to the adoption of the cover body structure, so that the friction between the cover body and the valve body is reduced, and the service life of the valve is prolonged.

Description

A kind of sealed valve

Technical field

The present invention relates to valve and manufacture field, especially relate to a kind of sealed valve.

Background technique

Valve is the controlling component in fluid delivery system, there is cut-off, adjusting, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, need very little moment of rotation during operated valve, its compact structure, easy operating and maintenance, suitable directly doing opens and closes use, extensive use on engineering, existing valve mechanism, the use of ball valve is the most extensive, because between the valve seat of ball valve and spool, close contact forms hard sealing, between them, in very strong friction, relative movement occurs, loss occurs in friction, and it is not very flexible also making valve switch.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of be not easy to occur wearing and tearing and sealed valve easy to maintenance.

The present invention solves the technological scheme that its technical problem takes: a kind of sealed valve, comprise valve body, spool, valve rod and handwheel, spool is connected with valve rod, valve rod is connected with handwheel, spool and valve rod are positioned at valve inner, valve body is provided with an entrance and an outlet, described spool comprises the briquetting be connected with valve rod, be provided with lid in the entrance of valve inner and outlet, being provided with a rotating shaft on the top of lid is connected with valve body, be respectively equipped with first in the both sides of lid and be rotationally connected bar, rotate and be provided with V-type lever in the valve body bottom, V-type lever one end and first is rotationally connected bar and is rotationally connected, the other end is rotationally connected bar by second and briquetting is rotationally connected.

Further concrete, be provided with spring between described briquetting and valve rod.

Further, in order to make valve, good sealing effect is arranged, described lid is provided with for sealing the seal ring of entrance and exit

Effect intentionally of the present invention is: after having adopted said structure, due to what adopt, be cover body structure, when opening and closing, can not rotate, can reduce the friction between lid and valve body, extend the working life of valve.

The accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

In figure: 1, valve body; 2, briquetting; 3, valve rod; 4, handwheel; 5, spring; 6, rotating shaft; 7, lid; 8, entrance; 9, seal ring; 10, second be rotationally connected bar; 11, V-type lever; 12, outlet; 13, first be rotationally connected bar.

Embodiment

Below in conjunction with accompanying drawing, the present invention is described in detail.

A kind of sealed valve as shown in Figure 1, comprise valve body 1, spool, valve rod 3 and handwheel 4, spool is connected with valve rod 3, valve rod 3 is connected with handwheel 4, spool and valve rod 3 are positioned at valve body 1 inside, valve body 1 is provided with an entrance 8 and an outlet 12, described spool comprises the briquetting 2 be connected with valve rod 3, at the entrance 8 of valve body 1 inside and export on 12 and be provided with lid 7, be provided with a rotating shaft 6 is connected with valve body 1 on the top of lid 7, be respectively equipped with first in the both sides of lid 7 and be rotationally connected bar 13, rotate and be provided with V-type lever 11 in valve body 1 bottom, V-type lever 11 1 ends and first are rotationally connected bar 13 and are rotationally connected, the other end is rotationally connected bar 10 by second and is rotationally connected with briquetting 2, be provided with spring 5 between described briquetting 2 and valve rod 3, described lid 7 is provided with for sealing the seal ring 9 of entrance 8 and outlet 12.

The working principle of sealed valve is: the operator turns handwheel 4, handwheel 4 band ovable valve stems 3 rotate, valve rod 3 drives briquetting 2 and moves downward, briquetting 2 is to an end that presses down V-type lever 11, the other end perk of V-type lever 11, lid 7 is raised, and lid 7 is along rotating shaft 6 rotating opening, and current can pass through.

It is emphasized that: above is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
