Background

Sleeve valves are a variety developed in the sixties. The sleeve valve plug is used for throttling instead of the valve core and valve seat throttling of a single valve seat and a double valve seat. A diaphragm type sleeve valve is commonly used in the sleeve valve, and is a stop valve which uses a diaphragm as an opening and closing member to close a flow passage, cut off fluid, and separate an inner cavity of a valve body from an inner cavity of a valve cover. The diaphragm type sleeve valve is widely used in various fields, but the existing diaphragm type sleeve valve is often not tightly closed to cause liquid leakage in use, and the existing diaphragm type sleeve valve is complex in structure and high in manufacturing cost. Therefore, there is a great need to design a new type of internal diaphragm sleeve valve.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a built-in diaphragm type sleeve valve, includes the valve body, the inside fixed block of choking that is equipped with of valve body, two reposition of redundant personnel through-holes about choking block and valve body form respectively, there is lower valve gap below the valve body through bolt fixed mounting, there is the upper valve gap below the valve body through bolt fixed mounting, it installs the threaded rod to go up to rotate between valve gap and the lower valve gap, the threaded rod is located two reposition of redundant personnel through-hole position fixed mounting and has the baffle, lie in the baffle both sides on the threaded rod and install first valve plate symmetrical screw thread respectively, lie in the outside symmetrical screw thread of two first valve plates on the threaded rod and install the second valve plate, fixedly connected with diaphragm between the edge of first valve plate and second valve plate, the upper end of threaded rod runs through upper valve gap.

Preferably, rubber pads are bonded at the contact parts of the upper valve cover and the lower valve cover and the valve body.

The arrangement can ensure that the upper valve cover, the lower valve cover and the valve body are connected more closely to prevent liquid leakage.

Preferably, a silica gel pad is bonded on the side wall of the shunt through hole.

The silica gel pad is bonded on the side wall of the shunting through hole, so that the side wall of the shunting through hole is contacted with the diaphragm more closely, and water leakage is avoided.

Preferably, the thread directions of the threaded rod on the two sides of the partition plate are opposite.

Preferably, a sealing gasket is installed at the contact part of the threaded rod and the upper valve cover, and a bearing is installed at the contact part of the threaded rod and the lower valve cover.

The utility model discloses a technological effect and advantage: the utility model discloses an easy operation is convenient, only need rotate the knob alright adjust the valve body, and low in manufacturing cost. When needs cut rivers, the threaded rod rotates when rotating the knob, make first valve plate and second valve plate remove to keeping away from the baffle direction respectively, when the second valve plate passes through in the reposition of redundant personnel hole and first valve plate contacts with the inside wall of reposition of redundant personnel through-hole, diaphragm between first valve plate and the second valve plate and reposition of redundant personnel through-hole's lateral wall in close contact with, alright cut rivers, it has the silica gel pad to bond on the lateral wall of reposition of redundant personnel through-hole, can make contact between the lateral wall of reposition of redundant personnel through-hole and the diaphragm inseparabler, avoid leaking, when wanting rivers to circulate again, reverse knob makes first valve plate of threaded rod drive and second valve plate remove to the baffle direction, rivers alright flow from reposition of redundant personnel through-hole.
