Abstract

The invention discloses a novel multi-rotation valve device which can reduce the valve torque and prolong the service life of padding. The novel multi-rotation valve device comprises a valve cover and a valve rod, the valve cover is provided with a grease injection hole, an injection molding retainer is arranged in a manner of being communicated with the grease injection hole, and upper lip type self-sealing padding and lower lip type self-sealing padding are arranged above and below the injection molding retainer correspondingly; and a ring of graphite is arranged above the upper lip type self-sealing padding, and a padding backing ring is arranged below the lower lip type self-sealing padding. Compared with the prior art, the scheme has the beneficial effect that the padding height is reduced by 1/3; compared with a packing sealing structure with six to seven rings of graphite, the valve torque is reduced by 30%; the injection molding retainer is arranged between the lip type self-sealing padding, sealing grease can be injected at any time in the using process, long-time sealing of the valve rod padding is kept, and the service life of the padding is prolonged; and friction torque with the valve rod is reduced.

Description

New many turning valve devices
Technical field
The invention belongs to valving field, more particularly to the valve for turning round stem structure more.
Background technology
Valve is used as liquid, gas medium conveying equipment, it is widely used to the fields such as chemical industry, metallurgy, oil, mine, agricultural, in existing valve industry, graphite packing sealed valve stem structure is used wherein many revolving structure valves more, this structure valve torque is larger, and filler is easily extruded in the gap that valve rod coordinates with bonnet, forms abrasion, cause filler service life short, and valve is frequently repaired.
The content of the invention
In order to solve the above problems, the invention provides a kind of many turning valve devices for reducing valve torque, extension filler service life.
According to an aspect of the present invention, a kind of many turning valve devices, including bonnet and valve rod are provided, the bonnet is provided with greasing hole, connected with the greasing hole and be provided with injection spacer ring, the injection spacer ring upper and lower is respectively provided with lip type self-sealing packing and lower lip type self-sealing packing on a circle.
In some embodiments, it is provided with a circle graphite above the upper lip type self-sealing packing.
In some embodiments, it is provided with filler gasket ring below the lower lip type self-sealing packing.
The purpose of the present invention is the filling-material structure in a kind of many turning valves of design, original graphite packing is changed to lip type self-sealing packing, a lip type self-sealing packing is respectively set up and down, and an injection spacer ring is placed in centre, and stop-leak compound can be injected when using makes filler strut sealing for filler provides pressure.Its advantage is:Using such scheme compared with prior art, packed height reduces 1/3;Graphite packing sealing structures are enclosed compared to 6 ~ 7, valve torque reduces 30%;Injection spacer ring is provided with the middle of lip type self-sealing packing structure, stop-leak compound can be injected, stop-leak compound can be at any time injected in use, keep the permanent sealing of valve stem packing and the service life of increase filler;Reduce the friction torque with valve rod, facilitate the maintenance of filler and extend the service life of filler.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure:1- bonnets, 2- valve rods, 3- greasings hole, 4- injection spacer rings, the upper lip type self-sealing packings of 5-, lip type self-sealing packing under 6-, 7- filler gasket rings, 8- graphite.
Specific embodiment
1 the present invention is further illustrated below in conjunction with the accompanying drawings.Accompanying drawing 1 schematically shows many turning valve devices of the invention, including bonnet 1 and valve rod 2, the bonnet 1 is provided with greasing hole 3, is connected with the greasing hole 3 and is provided with injection spacer ring 4, and the injection upper and lower of spacer ring 4 is respectively provided with lip type self-sealing packing 5 and lower lip type self-sealing packing 6 on a circle.
Preferably, the top of the upper lip type self-sealing packing 5 is provided with a circle graphite 8.
Preferably, the lower section of the lower lip type self-sealing packing 6 is provided with filler gasket ring 7.
With reference to accompanying drawing 1, during installation, filler gasket ring 7 is first put into, then lip type self-sealing packing 5 on a circle is put in the top of filler gasket ring 7, is then placed in being molded spacer ring 4, lip type self-sealing packing 6 under putting a circle again on injection spacer ring 4 finally puts a circle graphite 8, compresses.After installation, by the greasing hole 3 on bonnet 1, stop-leak compound can be injected.It was verified that being obviously reduced using the valve torque of the structure, sealing property is more excellent.
Above-described is only some embodiments of the present invention, it is noted that for the person of ordinary skill of the art, on the premise of creation design of the invention is not departed from, can also make other deformations and improve, and these belong to protection scope of the present invention.
