Abstract
The utility model relates to a pressure reducing valve, which solves the problems of a small body and performance. The utility model comprises a valve body and a control room, wherein a valve seat is arranged in the valve body, linking guide rods are arranged in the valve seat and the centre of the control room, diaphragms are arranged in middle parts of the linking guide rods, both sides of the valve body and the control room are respectively provided with flow pipeline mouths, are connected with pipelines, and are communicated with a main flow pipeline of the valve body, a one-way valve and a needle valve are arranged on a pipeline between the flow pipeline mouths in one side of the control room and the valve body, a guide valve and a stop valve are arranged on a pipeline between the flow pipeline mouths in other side of the control room and the valve body, guide holes are arranged in the lower end of the valve seat, the linking guide rods pass through the guide holes, and valve clacks are arranged in the upper end of the valve seat on the linking guide rods. The utility model is used for water supply and drainage.
Description
The utility model relates to pressure maintaining valve, refers in particular to a kind of plumbing with decompression voltage stabilizing valve.
Common decompression venting valve reduces pressure by the pressure of spring, along with the increase of latus rectum, the number of coils and spring diameter have to increase, and cause valve body big and stupid, limited by installing space, because flap is limited by spring also, open amount can't increase, and makes the pressure regulation range little, flow is little, resistance is big, and part is many, and the precision height is made difficulty.
The plumbing decompression venting valve that the purpose of this utility model provides that a kind of body is little, regulation range broad, flow can be big.
The purpose of this utility model is achieved in that the plumbing decompression venting valve, and it comprises valve body, control room; Valve seat is arranged in the valve body, and there are the interlock guide rod in valve seat and control room central authorities, and there is diaphragm at the interlock guide rod middle part that top is with spring, it is characterized in that: the both sides in valve body and control room respectively are provided with the runner mouth respectively and have pipeline to connect and logical with valve body sprue structure; Wherein, the pipeline between the runner mouth of control room and valve body one side is provided with one-way valve and needle-valve; Control room and the valve body in addition pipeline between the runner mouth of side are provided with pilot valve and stop valve; The valve seat lower end is provided with guide hole, the interlock guide rod pass guide hole and on the interlock guide rod, valve seat upper end is provided with flap.
In the above-mentioned design, pilot valve is regulated pressure, replaces spring, realizes reduced volume, enlarges regulation range, and manually moment is little and need not rotate; Opening and closing stop valve can make sprue smooth, himself function is arranged again, make simple and compact for structurely, each only is 1/2 of existing decompression venting valve height and weight, the maximum open area of flap is near drift diameter area, easy for installation, can level install, also can vertically install, good seal performance, use is received the order long, because driving torque is very little, so operation is also very convenient laborsaving.
Below by drawings and Examples the novel of this practicality is described further again.
Fig. 1 is the utility model structural representation.
As shown in Figure 1: the utility model is made up of valve A, control room B, and valve seat 11 is arranged in the valve A, and there are interlock guide rod 15 in valve seat 11 and control room B central authorities, and there is diaphragm 14 at interlock guide rod 15 middle parts that top is with spring; The both sides of valve A and control room B are respectively established runner mouth 1,2,3,4 respectively, and pipeline 20 connections are arranged and lead to into the loop with valve A sprue 18 structures; Wherein, the pipeline between control room B and the valve A one effluent road junction 1,3 is provided with one-way valve 5, needle-valve 6; Pipeline between the effluent road junction 2,4 is provided with pilot valve 7, stop valve 8 in addition; Valve seat 11 lower ends are provided with guide hole 12, and promptly valve seat 11 is an one with the guide hole body, interlock guide rod 15 pass guide hole 12 and on interlock guide rod 15, valve seat 11 upper ends are provided with flap 10.Spanner 16 is arranged on the stop valve 8, pressure gauge 17 is arranged on the pipeline 20.Flap 10 is provided with sealing gasket 19, can avoid the defective of being blown off with the O RunddichtringO; Valve seat 11 adopts with valve A and goes up dress formula structure, and its contacting point is provided with chamfering and is provided with O RunddichtringO 13, can prevent that string from pressing and bounce-back is loosening.Establish adjusting screw 9 on the pilot valve 7, when it turned clockwise, control room B pressure increased, otherwise reduces.Diaphragm 14 interlock guide rods 15 and flap 10, that realizes flap 10 opens and closes and regulates flow and pressure.When sprue 18 stopped to supply water, flap 10 by diaphragm 14 interlock guide rods 15 energy self closing valve seats 11, had the safety check function under the pressure of control room B; The backflow of closing control chamber B, control room B internal pressure increases, and because of the twice of diaphragm design area greater than flap 10 areas, by the pressure promotion diaphragm 14 interlock guide rods 15 of control room B, flap 10 is closed sprue 18, has the stop valve function.The utility model can be designed to series product more than latus rectum 50mm, be applicable to high level, non-tall building plumbing decompression voltage stabilizing occasion.
