Abstract
The utility model relates to a filtration non-return valve. The filtration non-return valve comprises a valve body which is serially arranged between fluid pipelines and is provided with a spring guide rod control valve cover, and is characterized in that: a filter core is arranged at a valve port between an inlet section and an outlet section of the valve body; a filter core assembling and disassembling hole is formed on the lower part of the valve body; and a filter core seal cover is pressed outside the filter core assembling and disassembling hole. According to the filtration non-return valve, a filtering device is arranged in the valve body, so that impurity-containing fluid media in a pipeline system can be effectively filtered and removed; and simultaneously, impurities can be prevented from staying at a sealing piece, so that the sealing performance of the valve cannot be influenced, and other equipment in the valve and the pipeline system can be normally used. The filtration non-return valve has a simple and compact structure, a small volume and light weight and is high in sealing performance, extremely convenient to mount and maintain, low in cost and convenient to transport, a good effect that the valve is quick, convenient, safe and firm is achieved, and the conditions that the service life of the pipelines and the valve is prolonged, enterprise cost is reduced and production benefits are improved are facilitated.
Description
Technical field
The utility model belongs to the liquid flow-conditioning technical field, relates to a kind of logical filter check valve that closes of Control Engineering pipe-line system rate-of flow that is used for.
Background technique
At present the safety check in various pipe-line systems usually causes the safety check can't proper functioning because of the impurity that pipeline internal medium exists, and severe patient even possibly cause the equipment in the pipe-line system to be destroyed influences the working life of pipe-line equipment and valve.Because the safety check of conventional construction itself does not have decontamination function; Conventional in the past solution was a design special scrubbing filter plant in pipe-line system, and this mode exists in application process installs complicated, shortcomings such as connected element is many, be easy to generate leakages, volume is big, inconveniently keep in repair (more unfavorable repairing), lose time, cost height.
The model utility content
The purpose of the utility model is to overcome the deficiency that existing technology exists, provide a kind of simple in structure, easy to use, cost is low, can effectively remove the filter check valve of the impurity in the pipe-line system medium.
Be used to realize that the technical solution of foregoing invention purpose is such: the filter check valve that is provided comprises can going here and there for one adorns the valve body that is arranged between fluid line and has the spring guide application valve cover; It is characterized in that the valve port place between valve body inducer and outlet section is equipped with filter core; Have the assembling and disassembling filter element hole in the bottom of valve body, outside the assembling and disassembling filter element hole, be pressed with the filter core capping.
Compare with existing like product; The utility model is owing to be provided with filtrating equipment in valve body; Make pipe-line system have the flowing medium of impurity to be able to filtered effectively remove; Simultaneously can prevent effectively that impurity from resting on the Sealing position, guarantee that valve influences airtight performance, guarantee the normal use of miscellaneous equipment in valve and the pipe-line system.Simple and compact for structure, the airtight performance of the utility model is good, installation and maintenance is all very convenient, cost is low, volume is little; In light weight, be convenient to the transportation; Compare with other valve and can save the lay day more than 60%; Reach good result not only quick and convenient but also that safety is firm, help improving pipeline and valve working life, reduce entreprise cost and improve productivity effect.
The Applicable media of the utility model comprises many clocks media such as purified water, fresh water, sewage, seawater, gas, food, medicine, oils, acids, bases, salt; Product can be applicable in oil, rock gas, medicine, food, environmental protection, electric power, feedwater, draining, fire-fighting and the field of ventilation, also can use in a large number in the fluid system and the high-tech areas such as national defence, space flight of metallurgical production, boats and ships, vehicle, aircraft and movable machinery.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
The title of each label is respectively in the accompanying drawing: 1-valve body, the capping of 2-filter core, 3-filter core, 4-nut bolt, 5-valve gap, 6-non-return flap, 7-spring.
Embodiment
Below will combine accompanying drawing that the utility model content is further specified, but the practical application form of the utility model is not limited in illustrated embodiment.
Referring to accompanying drawing; The described filter check valve of the utility model is made up of elasticity guide rod valve plate formula hydraulic control valve and dismountable dirt filtrating equipment of being fitted in the hydraulic control valve valve body 1; Said dirt filtrating equipment comprises the filter core 3 and a filter core capping 2 that is pressed on place, valve body lower portion assembling and disassembling filter element hole that can be contained in valve port place between interior inducer of valve body and the outlet section; Can be during enforcement according to the aperture and the hole count of the actual demand of pipe-line system design filter core 3, can realize automatic fitration behind the logical filter core 3 of All Media, the medium automatic transport behind the contaminant filter is transferred to the pipe-line system after the inflow of outlet port to the Sealing position of valve; Need only unload filtering capping 2 when removing contamination; Take out filter core 3 and can remove foul,, load onto filtration capping 2 again and just can accomplish the blowdown operation then with filter core 3 reinstalls.The hydraulic control valve part of the utility model is made up of valve body 1, non-return flap 6, valve gap 5, spring 7, correcting bar and external related accessory (pressure gauge, thermometer, pilot valve, needle-valve etc.); Utilize the upstream and downstream pressure difference Δ P in self pipe-line system to be power during work; Automatically regulate by pilot valve control and by waterpower, close fully or the complete opening state thereby make non-return flap 6 be in adjustment state or be in.The non-return flap 6 of this filter check valve adopts the high-molecular special composite material that rebound elasticity is good, wear resistance is high, friction factor is little to process, and airtight performance is good, can reach airtight zero leakage.This filter check valve can be according to the change of pipe-line system and according to related needs such as application target, functions again; Exchange the product (like decompression, voltage stabilizing, pressure release, the control of remote control water level, flow control, safety check etc.) that becomes to satisfy the relevant art index through the mode that changes external pilot valve; Need not dismantle main valve; Energy saving improves effect, guarantees that valve and ducted other equipment normally use.
