Abstract

The utility model relates to a sealing valve which comprises a valve body, a valve element, a valve rod and a hand wheel. The valve element is connected with the valve rod which is connected with the hand wheel, the valve element and the valve rod are arranged in the valve body, and the valve body is provided with an inlet and an outlet. The valve element comprises a pressing block connected with the valve rod, cover bodies are arranged on the inlet and the outlet in the valve body, and the top end of each cover body is provided with a rotation shaft connected with the valve body. The two sides of each cover body are respectively provided with a first rotating connection rod, a V-shaped lever is arranged at the bottom of the valve body in a rotating mode, one end of the V-shaped lever is connected with the corresponding first rotating connection rod in a rotating mode, and the other end of the V-shaped lever is connected with the pressing block in a rotating mode through a second rotating connection rod. Due to the fact that the cover body structure is adopted, the cover bodies can not rotate in the opening and closing processes, friction between the cover bodies and the valve body can be reduced, and the service life of the valve is prolonged.

Description

Sealed valve

Technical field

The utility model relates to valve and manufactures field, especially relates 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, during operated valve, need very little moment of rotation, its compact structure, easy operating and maintenance, suitable directly doing opens and closes use, extensive use in engineering, existing valve mechanism, the use of ball valve is the most extensive, because close contact forms hard sealing between the valve seat of ball valve and spool, between them, in very strong friction, relative movement occurs, there is loss in friction, it is not very flexible also making valve switch.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of be not easy to occur wearing and tearing and sealed valve easy to maintenance.

The technical scheme in the invention for solving the technical problem is: 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 being connected with valve rod, in the entrance of valve inner and outlet, be provided with lid, on the top of lid, being provided with a rotating shaft is connected with valve body, in the both sides of lid, be respectively equipped with first and be rotationally connected bar, in valve body bottom, rotate and be provided with V-type lever, 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, between described briquetting and valve rod, be provided with spring.

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

Effect intentionally of the present utility model 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.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

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 utility model 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 being connected with valve rod 3, at the entrance 8 of valve body 1 inside and export and be provided with lid 7 on 12, on the top of lid 7, being provided with a rotating shaft 6 is connected with valve body 1, in the both sides of lid 7, be respectively equipped with first and be rotationally connected bar 13, in valve body 1 bottom, rotate and be provided with V-type lever 11, V-type lever 11 one end 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, between described briquetting 2 and valve rod 3, be provided with spring 5, 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: operator turns handwheel 4, handwheel 4 band ovable valve stems 3 rotate, valve rod 3 drives briquetting 2 to move downward, briquetting 2 is to the one 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: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
