Abstract

The utility model provides a withdrawable pressure reducing valve which comprises an outlet medium pressure adjusting component, a shell, a filter screen, a membrane component and a piston component, wherein the outlet medium pressure adjusting component is arranged in a valve body and a valve cover and consists of an adjusting screw bolt, a positioning piece and a pressure adjusting spring; the membrane component and the piston component form into a valve core; the membrane component consists of a fixed screw bolt, a press ring and a membrane; and the piston component consists of a valve rod, a valve clack and a valve clack seat. Due to the design, the withdrawable pressure reducing valve is combined with the blocking-proof filter screen, simplifies a pipeline, leads the valve core to be movably connected with the valve body since the valve core is designed to be withdrawable, can inherently and functionally play a part in pressure reducing as the existing pressure reducing valve, has not only good sealing performance but also dual functions of impurity filtering and blocking resisting since the valve body is sealed with the valve cover by clamping the membrane, and is more convenient to withdraw the valve core to wash or change the damaged parts, thereby improving the service life of a valve.

Description

The drawing out type reduction valve
Technical field
The utility model relates to a kind of reduction valve, relates in particular to a kind of drawing out type reduction valve.
Background technique
Reduction valve is a kind of pressure controlled valve, it is the control valve unit that can reduce working pressure of pipeline automatically, be widely used in tall building, too high zone, mine and other occasion of city water-supply pipe network hydraulic pressure, each obtains suitable service hydraulic pressure and flow with water spot in the water system to ensure to.Owing to the open degree that reduction valve is common is less, stopped up by impurity floating in the medium, silt particle easily and cause defective valve, even install the normal working life that filter can not guarantee fixed valve core structure, cause the narrow limitation in the reduction valve use.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of working pressure of pipeline that can reduce is provided, can make the timely disassembly, cleaning of spool again, prevent impurity in the medium from stopping up and cause the drawing out type reduction valve of defective valve, thereby reach the simplification pipeline, improve the valve purpose in working life.
Goal of the invention of the present utility model realizes by following technical proposals:
A kind of drawing out type reduction valve, it comprises valve body and the valve gap that is threaded, and is provided with the adjusting part and the spool of outlet pressure medium in described valve body and the valve gap, described adjusting part is formed by regulating bolt, location piece and pressure adjusting spring, it is characterized in that:
Be provided with the housing that is tightly connected in a, the described valve body;
B, described spool comprise be located in the housing, interconnected diaphragm unit and piston assembly form, described diaphragm unit is made up of set screw, trim ring and diaphragm, described diaphragm is clamped by valve body, valve gap; Described piston assembly is formed by being connected and fixed valve rod screw and that be connected with housing seal, flap and flap seat.
Be provided with filter screen between described housing and the medium entrance point, and the formation waterway communicates with medium inlet/outlet end.
Being tightly connected between described housing and the valve body is provided in a side of " O " RunddichtringO on both junction planes.
Being tightly connected between described valve rod and the housing is provided in a side of " O " RunddichtringO on both junction planes.
Compare with existing reduction valve, the utility model is combined reduction valve and anticlogging filter screen to simplify pipeline on the one hand; On the other hand spool design is become drawing out type, make no fixed linkage structure between spool and the valve body, make this reduction valve not only on function, play the due effect of reduction valve, impurity screening, anticlogging dual functions are arranged again, more can conveniently extract and clean, greatly reduce the malfunctioning probability of reduction valve, and when spool damages, can change fast, improve the operating life of valve; Owing to be provided with the diaphragm of clamping between valve body and the valve gap, improved the sealing of this valve simultaneously.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present utility model.
Embodiment
Below in conjunction with above-mentioned accompanying drawing the utility model embodiment is described in detail again.
As shown in Figure 1, the drawing out type reduction valve comprises the valve body 1 and the valve gap 13 that are threaded, and valve body and valve gap are any angle of inclination or vertical relation, design by the concrete structure position of pipeline.Be provided with housing 5 in the valve body, on both junction planes, be tightly connected, outside the housing 5 of medium entrance point, be arranged with filter screen 6 simultaneously, and formation waterway 16 communicates with medium inlet/outlet end with " O " RunddichtringO 4; Be located at outlet pressure medium adjusting part in valve body 1 and the valve gap 13 by regulating bolt 15, location piece 14 and pressure adjusting spring 12 are formed, make the mobile vertically pushing tow pressure adjusting spring 12 of location piece 14 reach the purpose that the outlet pressure medium is regulated by handling adjusting bolt 15, location piece 14 can only move axially in valve gap 13 and can not rotate, therefore it is directed with being connected of valve gap inner chamber, for example the valve gap inner chamber is designed to Hexagon, corresponding location piece also is designed to the Hexagon that is equipped with, perhaps other polygonal, also can be designed to combining of key and groove, regulate bolt during assembling, location piece, pressure adjusting spring all installs before valve gap is connected upper valve body in advance.
The spool design of reduction valve becomes drawing out type, comprise be located in the housing 5, interconnected diaphragm unit and piston assembly form.Described diaphragm unit is made up of set screw 11, trim ring 10 and diaphragm 9, and constitutes the sealing of valve body 1 and valve gap 13 by diaphragm 9.Described piston assembly is made up of valve rod 8, flap 3 and flap seat 2, the valve rod upper end is threaded with the set screw of diaphragm unit, the lower end is threaded with the flap seat, be tightly connected with 7 formation of " O " RunddichtringO on the junction plane of valve rod 8 and housing 5, piston assembly mainly plays sealing and decompression.
This reduction valve medium is discharged by outlet end through filter screen 6, waterway 16, the valve port that forms through flap 3 and housing 5 again by entrance point.The adjusting bolt 15 of the outlet pressure medium adjusting part by handling the reduction valve top, through location piece 14, pressure adjusting spring 12, again through diaphragm unit and piston assembly, make flap 3 and housing 5 form the valve port of different opening, reach outlet medium different pressures and regulate purpose.
When medium passed through reduction valve, filter screen 6 at first kept off most of impurity in valve body 1 inlet, guaranteed that flap 3 can be not malfunctioning because impurity stops up.If impurity is piled up and made it can't proper functioning the time in the reduction valve, can solve fast by following steps:
1, the stop valve before and after the reduction valve is closed;
2, the adjusting bolt 15 on the reduction valve valve gap 13 is rotated in the counterclockwise direction pressure adjusting spring 12 is totally released;
3, pull down valve gap 13;
4, with needle-nose pliers spool is comprised that housing 5 and filter screen 6 extract simultaneously;
5, housing, filter screen and the spool of pulling down thoroughly cleaned, perhaps change in case of necessity;
6, reinstall adjusting pressure.
Because no fixed linkage structure between the design's spool and the valve body can extract easily and clean, and greatly reduces the malfunctioning probability of reduction valve, and can change fast when spool damages, and has improved the valve working life-span.
