Abstract
A kind of pressure control fore filter of the present utility model, comprise trap valve, described trap valve is provided with water inlet port and the water outlet port of horizontal direction opening, this trap valve also offers Pressure gauge port, described trap valve is also provided with the through hole of up/down perforation, described through hole upper end is connected with adjusting pressuring knob, and described through hole lower end is connected with filtration barrel body, and described filtration barrel body lower end is also connected with blowdown valve body; Be provided with pressure regulation connecting rod in described trap valve, this pressure regulation small end is connected with adjusting pressuring knob, and lower end is set with spring pressuring plate; In described filtration barrel body, relief pressure valve cartridge is installed, above described relief pressure valve cartridge and between spring pressuring plate, relief spring is installed.A kind of pressure control fore filter of the present utility model with pressure-reducing valve solve the flimsy problem of the excessive water equipment caused of hydraulic pressure, increase the service life of water equipment.
Description
Technical field
The utility model relates to a kind of pressure control fore filter.
Background technology
Fore filter is generally arranged on the front end of pipeline, thus with " preposition " two word name; And " filtration ", then refer to the general principle of this kind equipment.Be generally T-shape structure.The two ends, left and right, position of " one is horizontal " are above respectively intake-outlet." one erects " position is below fuselage and inner cylindrical filter sieve, is then sewage draining exit bottom, controls to open and close by a valve.After fore filter is arranged on inlet channel water meter usually, to guarantee that a large amount of precipitated impurities produced in pipe network can not damage human body, and positive protective effect is played to concealed pipe, tap, electrical equipment etc.Fore filter is the jinx of secondary pollution, is a kind of device for filtering impurities reliably.Domestic type fore filter is the first coarse filtration equipment to full room water, can silt in Filtered tap water, iron rust, large particulate matter.
The accuracy rating of fore filter filter screen is not according to different brands and model from 5-300 micron etc., the granule foreign that the precipitated impurities that main removal pipeline produces and bacterium, microorganism remains, iron rust, husky mud etc. are greater than more than 5 microns, avoids human body and skin to come to harm; And play positive protective effect to downstream line, water purifier, water heater, washing machine, high-grade tap, flower Samburu, fore filter can also add " hydrochloric acid rephosphorization " scale inhibition filter core plays scale inhibition effect to solar energy, boiler.
But conventional fore filter does not have pressure control effect, if hydraulic pressure is excessive and can not turn hydraulic pressure down by Timeliness coverage, easily damage is caused to water equipment, reduce the service life of water equipment.
Utility model content
For overcoming the above problems, the utility model provides and a kind ofly prevents hydraulic pressure excessive and damage the pressure control fore filter of water equipment.
A kind of pressure control fore filter that the utility model provides, comprise trap valve, described trap valve is provided with water inlet port and the water outlet port of horizontal direction opening, this trap valve also offers Pressure gauge port, described trap valve is also provided with the through hole of up/down perforation, described through hole upper end is connected with adjusting pressuring knob, and described through hole lower end is connected with filtration barrel body, and described filtration barrel body lower end is also connected with blowdown valve body; Be provided with pressure regulation connecting rod in described trap valve, this pressure regulation small end is connected with adjusting pressuring knob, and lower end is set with spring pressuring plate; In described filtration barrel body, relief pressure valve cartridge is installed, above described relief pressure valve cartridge and between spring pressuring plate, relief spring is installed.
Pressure-reducing valve is provided with in the pressure control fore filter of the technical program, comprise pressure regulation connecting rod, adjusting pressuring knob, spring pressuring plate, relief spring and relief pressure valve cartridge, the flow that this pressure regulator valve can control water reaches the effect of decompression, the excessive damage easily causing water equipment of hydraulic pressure, adds pressure-reducing valve and carries out to hydraulic pressure the service life that decompression can increase water equipment.
Further, described Pressure gauge port is on same level line with water inlet port and water outlet port, and with water inlet port and water outlet port angle all in 90 °.
The Pressure gauge port of the technical program is used for Bonding pressure table, in real time monitoring hydraulic pressure size.
Further, described adjusting pressuring knob and through hole are for being threaded, and described through hole and filtration barrel body are for being threaded.
The through hole of the technical program is with adjusting pressuring knob and filtration barrel body and is threaded, and makes it interconnective more firm.
Further, described pressure regulation connecting rod lower end screw thread is movably installed with spring pressuring plate.
The spring pressuring plate of the technical program is for assisting relief spring work.
Further, described relief pressure valve cartridge upper end is set with sealing ring.
The sealing ring of the technical program for assisting the work of relief pressure valve cartridge, for assisted decompression.
Using method of the present utility model is: move adjusting pressuring knob with hand-screw, drives pressure regulation link rotatable, and then drives spring pressuring plate to move up and down, make relief spring stressed, relief spring just produces the effect of power to adjusting pressuring valve core, thus reaches the effect controlling discharge, produces effect of easing stress.
A kind of pressure control fore filter that the utility model provides with pressure-reducing valve solve the flimsy problem of the excessive water equipment caused of hydraulic pressure, increase the service life of water equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is fractionation schematic diagram of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of pressure control fore filter, comprise trap valve 1, described trap valve 1 is provided with water inlet port 2 and the water outlet port 3 of horizontal direction opening, this trap valve 1 also offers Pressure gauge port 4, described Pressure gauge port 4 is on same level line with water inlet port 2 and water outlet port 3, and with water inlet port 2 and water outlet port 3 angle all in 90 °, described trap valve 1 is also provided with the through hole 5 of up/down perforation, described through hole 5 threaded upper ends is connected with adjusting pressuring knob 6, described through hole 5 lower end has been threaded filtration barrel body 7, described filtration barrel body 7 lower end is also connected with blowdown valve body 8, be provided with pressure regulation connecting rod 9 in described trap valve 1, this pressure regulation connecting rod 9 upper end is connected with adjusting pressuring knob 6, and lower end screw thread is movably installed with spring pressuring plate 10, be provided with relief pressure valve cartridge 11 in described filtration barrel body 7, this relief pressure valve cartridge 11 upper end is set with sealing ring 12, is provided with relief spring 13 above described relief pressure valve cartridge 11 and between spring pressuring plate 10.
A kind of pressure control fore filter that the present embodiment provides with pressure-reducing valve solve the flimsy problem of the excessive water equipment caused of hydraulic pressure, increase the service life of water equipment.
