Abstract
The utility model relates to a gate valve, which comprises the following components: a valve body, a valve cove, the valve rod, the packing box, gland, the flashboard, and handle, valve body upper portion seal installation valve gap, valve gap upper portion flange joint gland, the vertical flashboard that sets up in the valve body, flashboard and valve rod fixed connection, the valve rod is the coaxial valve gap that passes in proper order upwards, gland, bottom surface middle part system has a radial bulge loop under the valve body, coaxial coating rubber sealing layer on the bulge loop, there is a recess at flashboard lower extreme face diameter to the system, the valve body is closed, bulge loop coaxial sealing inlays the dress in the recess of flashboard. The application provides a gate valve has the half -turn bulge loop in valve body bottom system, and the bottom surface is provided with the axial notch under the flashboard, work as the fluid passage, in the time of need closing the valve, the below flashboard, be embedded into the bulge loop of valve body in the recess of flashboard can, easy operation does not conveniently retain liquid, does not corrode the valve body.
Description
Technical field
The utility model belongs to valve field, is a kind of Novel Brake Valve.
Background technique
The gate valve of Flange Gate Valves to be Placement be flange, this Placement is the most common.Reliable and stable when Flange Gate Valves uses in pipeline, so often adopt Flange Gate Valves on pressure duct.Moving direction and the flow direction of Flange Gate Valves flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, can not make adjustments and throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern gate valve form wedge shape, key groove is different with valve parameter, are generally 50.The flashboard of Wedge gate valve can make an entirety, is called rigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, make up the deviation that sealing surface angle produces in course of working, this flashboard is called Flexible disc.
Find following relevant to the application patent documentation by retrieval, concrete disclosure is as follows:
Patent documentation 102865379A discloses a kind of gate valve, comprise valve body and wedge shape flashboard, described wedge shape flashboard is provided with ram seal face, described valve body is provided with the sealed department coordinated with described ram seal face, described sealed department comprises the primary sealing area being located at body base and the secondary sealing area be located on valve body from top to bottom, primary sealing area and described secondary sealing area are an angle α, during gate valve closed condition, described secondary sealing area and described ram seal face gluing, sealing, form Seal cage between described primary sealing area and described wedge shape flashboard.
The open Flange Gate Valves of patent documentation 102155545A, comprise valve body, flashboard, flange, valve gap, valve rod, it is characterized in that, in valve body, valve seat is equipped with respectively in the left and right sides, is provided with wedge-type flashboard in valve seat, valve body two ends and pipeline connection port place are equipped with flange, valve body is connected with valve gap bolt, in the middle part of valve gap, valve rod is housed, and valve rod lower end is connected with flashboard, Stem Mut is equipped with on valve rod top, and Stem Mut upper end is connected with handwheel.
The flap that existing gate valve is all be all be inlaid in valve body lower portion groove in carry out to valve body sealing, the groove of so this existence can retain liquid usually, corrodes valve body, and this technology is urgently improved.Above-mentioned patent does not still address this problem.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cost low, etch-proof Novel Brake Valve.
The technological scheme that the utility model realizes object is as follows:
A kind of Novel Brake Valve, comprise valve body, valve gap, valve rod, stuffing box, Gland, flashboard and handle, valve gap is installed in valve body top seal, valve gap upper flange bonding pad gland, vertically arrange flashboard in valve body, flashboard is fixedly connected with valve rod, valve rod is upwards successively coaxially through valve gap, Gland, its end and handwheel are fixedly mounted with, and the inside of described valve gap upper end is provided with the stuffing box with valve gap one, and described stuffing box is built with stuffing box packing; In the middle part of valve body bottom surface, be shaped with a radial convex loop, coaxial coating rubber sealing layer on bulge loop, in flashboard lower end surface, radial direction is shaped with a groove, and valve body is closed, and bulge loop co-axial seal is inlaid in the groove of flashboard.
The beneficial effects of the utility model are:
1, the Novel Brake Valve that the application provides is shaped with half-turn bulge loop at body base, flashboard bottom surface is provided with axial notch, when liquid passes through, when needing throttle down, below flashboard, is embedded in the groove of flashboard by the bulge loop of valve body, simple to operation, not remaining liquid, does not corrode valve body.
2, the Novel Brake Valve that the application provides adopts the mode of valve body bulge loop and flashboard groove setting-in to carry out closing passage, and groove and bulge loop form two seals, improve the sealing of valve further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is part A enlarged diagram in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model successively.
A kind of Novel Brake Valve, comprise valve body 6, valve gap 5, valve rod 2, stuffing box 4, Gland 3, flashboard 7 and handle 1, valve gap is installed in valve body top seal, valve gap upper flange bonding pad gland, vertically arrange flashboard in valve body, flashboard is fixedly connected with valve rod, valve rod is upwards successively coaxially through valve gap, Gland, its end and handwheel are fixedly mounted with, and the inside of described valve gap upper end is provided with the stuffing box with valve gap one, and described stuffing box is built with stuffing box packing 4.
The innovation of the application is:
In the middle part of valve body bottom surface, be shaped with a radial convex loop 8, coaxial coating rubber sealing layer on bulge loop 8, be shaped with a groove 10 in flashboard lower end surface radial direction, valve body is closed, and bulge loop co-axial seal is inlaid in the groove of flashboard, completes the sealing of valve body.
The Novel Brake Valve that the application provides is shaped with half-turn bulge loop at body base, and flashboard bottom surface is provided with axial notch, when liquid passes through, when needing throttle down, below flashboard, is embedded in the groove of flashboard by the bulge loop of valve body, simple to operation, not remaining liquid, does not corrode valve body.
The Novel Brake Valve that the application provides adopts the mode of valve body bulge loop and flashboard groove setting-in to carry out closing passage, and groove and bulge loop form two seals, improves the sealing of valve further.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
