CN2235616Y - Multi-function combination type pressure measuring valve - Google Patents

Abstract

The utility model relates to a multi-function combination type pressure measuring valve used for measuring the pressure, the differential pressure and the flow capacity of fluid. The utility model is characterized in that one side of a main valve is provided with a blowdown joint, and the outer side of a condenser is provided with a plurality of heat radiating fins of which the inner parts are provided with U-shaped pipelines. The connection end of each component of the main valve, the condenser and the tee is in the interconnection of standard connector, so the mutual components can be assembled freely to form a modular composite structure and satisfy the connection purpose on site in any direction.

Description

Multi-functional combined pressure measuring valve

The utility model relates to the pressure measuring instruments field, belongs to a kind of pressure measuring valve of measuring pressure, pressure reduction and the flow of fluid in the measuring system specifically.

Currently used pressure measuring valve; wherein condenser all is a pancake coil; volume is easy fracture in installation or use greatly; the direction non-interchangeability of on-the-spot pipe laying, the tensimeter after installing appears in regular meeting can't guarantee positive apparent direction, solder joint is many simultaneously; as inflow point; condensers etc. directly influence measuring reliability, can not be fit to on-the-spot actual installation needs.

The purpose of this utility model provides a kind of cool condenser volume little, can not collapse and rupture, the pipe laying that can be fit to in-situ horizontal or vertical direction, the whole valve body solder joint is few, but and a kind of multi-functional combined pressure measuring valve with pressure release and dirt eliminating function and pipeline combination in any.

For finishing the technical scheme that above-mentioned purpose adopts: main valve, condenser, threeway, each end be the standard connector interconnect, so can form brick pattern and connect arbitrarily, main valve one side is provided with the blowdown joint, the some heat radiator of condenser arranged outside, inside is provided with U type tube passage, left and right screw thread is established at the connector two ends respectively, makes on-the-spot setting pressure table can guarantee positive apparent direction.

The utility model is because each end interface of each parts is standard interface, can be combined into long-pending formula structure arbitrarily mutually, the direction that satisfies on-the-spot any occasion connects, especially the U-shaped tube passage is established in condenser inside, some heat radiator are established in the outside, and volume greatly reduces, and establishes the blowdown joint on main valve, passage can be done, the usefulness of pressure release and blowdown can be played again.

The utility model embodiment is described in detail in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural drawing;

Fig. 2 is the second example structure figure;

Fig. 3 is a blowdown junction composition.

According to shown in Figure 1, main valve 4 a wherein side is established blowdown joint 7, one end connects connector 5, main valve 4 other ends connect condenser 3, condenser 3 other ends are established threeway 2, its threeway 2 two interfaces in addition all can connect pressure pipe 1, can be used for horizontal or vertical direction pipeline connects, the some heat radiator 9 of above-mentioned condenser arranged outside, inside is provided with U type pipe 8 and does the fluid-tight use, connector 5 two ends are provided with left and right sides screw thread, connect can guarantee positive aspect after first end connects tensimeter, and connector 5 one ends can be installed into the mouth pressure transmitter if connect crossover sub 6.

Another embodiment of the utility model as shown in Figure 2, present embodiment is used for vertical direction and installs, main valve 4 levels one end is established threeway 2 and pressure pipe 1 respectively, the vertical direction of main valve 4 connects condenser 3 by blowdown joint 7, condenser 3 connects connector 5 and tensimeter, and the other end of main valve 4 levels can be provided with pressure unit by connector 5 and crossover sub 6.

The utility model is because the link of main valve 4, threeway 2, condenser 3 is standard interface, so form brick pattern, installation direction can be set arbitrarily, one side of main valve 4 is established blowdown joint 7, can make things convenient for the dirt in the discharge line, Fig. 3 is the structural drawing of blowdown joint 7, blowdown 7 can be turned on when needing blowdown, blowdown joint 7 can be unscrewed when needing pressure release.

Claims (1)

1, a kind of multi-functional combined pressure measuring valve of measuring pressure, pressure reduction and the flow of fluid, form by main valve, pressure pipe, condenser, it is characterized in that main valve (4) one sides are provided with blowdown joint (7), main valve (4) one ends are established condenser (3) and threeway (2), the some heat radiator of condenser (3) arranged outside (9), establish U type tube passage (8) in the condenser (3), main valve (4) other end connects connector 5, left and right screw thread is established at connector 5 two ends respectively, and above-mentioned main valve (4), condenser (3), each link of threeway (2) parts are the standard connector and interconnect.
