Abstract
The utility model discloses a quick assembling type three-way converging regulating valve. A bottom flange (1) is arranged on a valve body (8), a valve holder is arranged in the valve body (8), a valve plug (5) is arranged on the valve holder, and the valve holder comprises an upper valve holder (6) and a lower valve holder (3); and the lower valve holder (3) is arranged on the bottom flange (1), the lower valve holder (3) is fixed through the pressure applied by the bottom flange (1), the lower valve holder (3) is provided with a valve cage (4), the valve cage (4) is provided with the upper valve holder (6), and the upper valve holder (6) is fixed by the pressure which is applied by the bottom flange (1) to fix the lower valve holder (3) and the valve cage (4). According to the quick assembling type three-way converging regulating valve disclosed by the utility model, the valve holder is not provided with any thread, so that the stress condition of the valve holder can be efficiently improved so as to make the processing, the grinding, the assembling and the maintenance convenient. The entire quick assembling type three-way converging regulating valve adopts the automatic center-aligned blocking type so as to ensure the coaxiality of a valve plug holder, and the valve plug can be rapidly assembled and disassembled without any special tool, so that the quick assembling type three-way converging regulating valve can enhance the labor productivity and the service life of the product, and has strong interchangeability.
Description
Technical field
The utility model relates to the universal machine valve, is specifically related to a kind of fast disassembly type three-way converging modulating valve.
Background technique
Existing three-way converging modulating valve mainly contains compositions such as valve body, valve seat, spool, pad, end flange, valve gap, filler, Gland, bolt and nut.It is fixed that wherein valve seat adopts screw thread, and valve seat is to lean on screw thread locked on valve body, and the shortcoming of this structure is: complex design, demolition and maintenance difficulty; Processing, assembling, grinding inconvenience need the special tool assembling, are not easy centering; Assembling difficulty is big; Manufacturing efficiency is low, is difficult to during frequent maintenance realize exchanging, and working life is short.
Summary of the invention
The utility model purpose is: a kind of fast disassembly type three-way converging modulating valve is provided; Avoid the deficiency of above-mentioned existing technology; Adopt no screw thread valve seat, effectively improve the means of fixation of valve seat, reduce processing, assembling, grinding, demolition and maintenance difficulty; And avoid that trim is difficult for that centering, interchangeability are poor, working life short problem, it is applicable to that the flow direction that on pipeline, changes medium and two kinds of stream media become a kind of stream medium, flow is regulated.
The purpose of the utility model realizes through following technical measures: it includes valve body, valve seat, spool and end flange; End flange is installed on the valve body, and valve seat is installed in the valve body, and spool is installed on the valve seat; It is characterized in that: valve seat is made up of upper valve base and lower valve base; Lower valve base is installed on the end flange, and lower valve base fixes through end flange applied pressure, and valve cage is installed on the lower valve base; Install valve seat on the valve cage, fixedly lower valve base and valve cage applied pressure fix upper valve base through end flange.
Wherein, place metal between end flange and the valve body and twine Graphite pad, place gasket seal between upper valve base and the valve body.
The beneficial effect that the utility model is compared existing technology is: 1, it can improve the force-bearing situation of valve seat effectively, and processing, grinding, assembling, maintenance and convenient have realized modular design; The whole valve assembly automatic centering heart is snap-in simultaneously; Need not install and remove by special tool, reduced product processing, assembling difficulty, thereby improved labor productivity; Interchangeability is strong, has improved product working life; 2, complete mounted the time when end flange, its strength is to be delivered to upper valve base through valve cage, can prevent to reveal so that gasket seal obtains suitable compression.
Description of drawings
Fig. 1 is the valve seat construction schematic representation of the utility model.
Fig. 2 is the cutaway top view of Fig. 1.
Among the figure: 1 end flange, 2 Graphite pads, 3 lower valve bases, 4 valve cages, 5 spools, 6 upper valve bases, 7 gasket seals, 8 valve bodies.
Embodiment
The technological solution party of the utility model further is detailed below in conjunction with accompanying drawing.
Like Fig. 1, shown in 2, it includes valve body 8, valve seat, spool 5 and end flange 1, and end flange 1 is installed on the valve body 8; Valve seat is installed in the valve body 8, and spool 5 is installed on the valve seat, it is characterized in that: valve seat is made up of upper valve base 6 and lower valve base 3; Lower valve base 3 is installed on the end flange 1, and lower valve base 3 fixes through end flange 1 applied pressure, and valve cage 4 is installed on the lower valve base 3; Install valve seat 6 on the valve cage 4, fixedly fix by lower valve base 3 and valve cage 4 applied pressures through end flange 1 for upper valve base 6.
Wherein, place metal between end flange 1 and the valve body 8 and twine Graphite pad 2, place gasket seal 7 between upper valve base 6 and the valve body 8.
Claims (2)
1. fast disassembly type three-way converging modulating valve, it includes valve body (8), valve seat, spool (5) and end flange (1), and end flange (1) is installed on the valve body (8); Valve seat is installed in the valve body (8); Spool (5) is installed on the valve seat, it is characterized in that: valve seat is made up of upper valve base (6) and lower valve base (3), and lower valve base (3) is installed on the end flange (1); Lower valve base (3) fixes through end flange (1) applied pressure; Lower valve base (3) go up to be installed valve cage (4), installs valve seat (6) on the valve cage (4), and fixedly lower valve base (3) and valve cage (4) applied pressure fix upper valve base (6) through end flange (1).
