Technical Field

The invention relates to the technical field of valve covers, in particular to a combined forged steel vacuum valve cover.

Background

The valve cover is a valve part provided with a valve rod sealing element and used for connecting or supporting the actuating mechanism.

Present valve gap divide into integral type valve gap and combination formula valve gap, however, at first, use the bolt to connect usually between the upper and lower valve gap of the valve gap of current combination formula, and the dismouting is troublesome, and the problem of screw thread inefficacy takes place easily for the bolt, leads to connecting the unstability between the upper and lower valve gap, and secondly, uses in other part equipment of valve gap and valve to when putting into operation, the impurity that mix with in the fluid often can pile up on the base, and impurity can't be discharged, can influence the whole work of valve body.

Disclosure of Invention

The invention aims to solve the problems and provides a combined forged steel vacuum valve cover.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a modular forged steel vacuum valve gap, includes inside upper valve gap and the lower valve gap of seting up the through-hole, upper valve cap bottom cup joints in the valve gap down, set up ring groove on the lower valve gap inner surface wall, the outside that upper valve cap is close to the bottom is provided with annular fixture block, annular fixture block joint is in ring groove, the upper valve gap outside is provided with the sleeve, the sleeve bottom is connected with the annular cardboard, the annular cardboard joint is on the flange of valve gap top down.

As a further description of the above technical solution:

first clamping grooves are formed in two sides of the bottom of the extending ends of the two sides of the flange at the top of the lower valve cover, first clamping blocks are correspondingly arranged on the annular clamping plates, and the first clamping blocks are clamped in the first clamping grooves.

As a further description of the above technical solution:

the improved structure is characterized in that grooves are formed in two sides of the inner surface wall of the sleeve, a second clamping block is arranged in each groove, the vertical section of each second clamping block is in a shape like a Chinese character 'ao' rotating clockwise by 90 degrees, a plurality of second clamping grooves are formed in the outer side of the upper valve cover, and the protruding portions of the second clamping blocks are clamped into the second clamping grooves.

As a further description of the above technical solution:

and the vertical end surface of the groove is elastically connected with the second fixture block through a spring.

As a further description of the above technical solution:

lower valve gap bottom has the base to connect firmly, the inside department of being close to the bottom of lower valve gap is equipped with the V-arrangement face, the roller is changeed in the rotation of V-arrangement face bottom through the bearing installation, it has the connecting plate to change roller both sides hard connection, connecting plate one side is provided with a plurality of brushes, and is a plurality of the brush contacts with the interior table wall of lower valve gap.

As a further description of the above technical solution:

a plurality of drain outlets are formed in the bottom of the base and communicated with the through hole in the lower valve cover.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. according to the invention, the upper valve cover and the lower valve cover are assembled and mounted by clamping the annular clamping block and the annular clamping groove and clamping the annular clamping plate and the flange at the top of the lower valve cover, so that the use of a bolt fastener is avoided, the problem of thread failure is avoided, and the upper valve cover and the lower valve cover are connected more stably by clamping the first clamping block and the first clamping groove.

2. According to the invention, the sleeve is stably sleeved on the outer side of the upper valve cover through the clamping connection between the second clamping block and the second clamping groove, so that the sleeve is convenient to detach and replace, and the sleeve is also a connecting piece between the upper valve cover and the lower valve cover.

3. According to the invention, when fluid flows through the rotating roller, the brush on the connecting plate synchronously rotates towards the rotating roller through the impact force of the fluid on the rotating roller and the connecting plate, so that impurities on the base are cleaned, the impurities can be periodically discharged from the sewage discharge port, the accumulation of the impurities is avoided, and the stable operation of the whole valve body is ensured.
