Description

Valve convenient to change sealing member

Technical Field

The utility model belongs to the technical field of the valve and specifically relates to a valve convenient to change sealing member is related to.

Background

The gate valve controls the conduction or stop of fluid in a pipeline by opening and closing the flashboard, the movement direction of the flashboard is perpendicular to the fluid direction, and when the flashboard is opened and closed, the valve rod moves up and down by rotating the hand wheel. The existing valve is provided with a plurality of sealing elements on the valve rod, and the sealing elements are sealed by rubber rings and need to be replaced periodically, so that the valve needs to be closed for replacement every time, and the production efficiency is directly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a valve convenient to change sealing member, under the open mode, can change the sealing member in the valve gap, convenient operation does not influence normal medium and flows.

In order to realize the above-mentioned purpose, the utility model provides a valve convenient to change sealing member, including valve body, valve gap and set up in this internal valve rod of valve, valve gap sealing mechanism and valve plate sealing mechanism have set gradually on the valve rod, valve plate sealing mechanism includes integral type valve plate and metal swivel nut, the metal swivel nut inlays to be located the integral type valve plate inside and with valve rod threaded connection, integral type valve plate top is provided with sealed frustum, be provided with in the valve gap with the frustum recess of sealed frustum looks adaptation.

Preferably, the integral type valve plate is rubber material and both sides are provided with the guide block, this internal guide slide that is provided with of valve.

Preferably, the valve cover sealing mechanism comprises a first sealing element, a non-metal spacer bush and a second sealing element which are sleeved on the valve rod from top to bottom in sequence.

Preferably, the valve cover is fixedly connected with the valve body through bolts, a pressing cover is fixed to the top of the valve cover, and the pressing cover is in contact with the top of the first sealing element.

Therefore, the utility model adopts the above structure a valve convenient to change sealing member, in sealed frustum got into the frustum recess, sealed frustum was used for the sealing between valve rod and the valve gap, was convenient for change the sealing member in the valve gap under the open mode, and convenient operation does not influence normal medium and flows.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
