Abstract
The utility model relates to a filter-type voltage-stabilizing valve which comprises a valve body, the valve body can be connected in series among fluid pipes, the valve body is provided with a ball valve and a pressure-reducing guide valve, a valve clack controlled by a spring pilot rod is pressed and sealed above a valve port between an inlet section and outlet section of the valve body, a filter screen is arranged below the valve port, and the lower part of the valve body is provided with a filter-screen installing and removing hole, and provided with a filter-screen close cover by way of press fitting. According to the utility model, because a filter device is arranged in the valve body, an impurity-containing fluid medium in a pipe system can be effectively removed, and a situation that impurities rest on sealing element parts can be prevented, thereby ensuring that the sealing performance of the valve is not influenced, and ensuring the normal application of the valve and other equipment in the pipe system. The filter-type voltage-stabilizing valve disclosed by the utility model is simple and compact in structure, good in sealing performance, extremely convenient to install and maintain, small in volume and convenient to transport, achieves quick, convenient, safe and firm effects, and facilitates the prolongation of the service lives of the pipes and the valve, the reduction of the enterprise cost and the improvement of production benefits.
Description
Technical field
The utility model belongs to the liquid flow-conditioning technical field, relates to a kind of logical filter-type pressure maintaining valve that closes of Control Engineering pipe-line system rate-of flow that is used for.
Background technique
At present the pressure maintaining valve 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, so provide a kind of simple in structure, easy to use, cost is low, can effectively remove the filter-type pressure maintaining 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-type pressure maintaining valve that is provided comprises can going here and there for one adorns the valve body that is arranged on the band valve gap between fluid line; Valve body is provided with ball valve and decompression pilot valve; It is characterized in that press seal has a flap by the control of spring correcting bar above the valve port between valve body inducer and the outlet section; Filter screen is housed below valve port, has the filter screen handling hole, outside the filter screen handling hole, be pressed with the filter screen capping in the bottom of valve body.
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 number designation is respectively in the accompanying drawing: 1-valve body, 2-flap, 3-sleeve pipe, 4-diaphragm, 5-(up and down) pallet; The 6-spring, 7-correcting bar, 8-ball valve, 9-needle-valve, 10-valve gap; The 11-pilot valve that reduces pressure, 12-conduit, 13-pressure gauge, the capping of 14-filter core, 15-filter screen.
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-type pressure maintaining valve of the utility model is made up of valve body 1, valve gap 10 and dismountable dirt filtrating equipment of being fitted in the valve body 1.Valve body 1 adopts the valve body of traditional guide rod flap formula hydraulic control valve; Valve body is provided with ball valve 8, decompression pilot valve 11, needle-valve 9, pressure gauge 13 etc.; Press seal has a flap 2 by 7 controls of spring correcting bar above the valve port between valve body 1 inducer and the outlet section, but this flap 2 is the taper piston flap that a bottom is provided with compensation sealing valve group, has the advantage of favorable sealing property; Can stop the drop seepage, reach sealing fully.In the practical application, can be according to the difference in valve body application target, function, pipe-line system medium, place, but through changing the sealing material of compensating type taper piston, valve body is designed to plain edition, filter-type, through-type, telescopic type and structure such as combined.The dirt filtrating equipment of establishing in this piston valve comprises the filter screen 15 and a filter screen capping 14 that is pressed on valve body lower portion filter screen handling hole place that can be contained in valve port place between interior inducer of valve body and the outlet section; Can design the aperture and the hole count of filter screen 15 during enforcement according to the actual demand of pipe-line system; Through the impurity in filter screen 15 filter mediums; Need only unload filtering capping 14 when removing contamination; Take out filter screen 15 and can remove foul,, load onto filtration capping 14 again and just can accomplish the blowdown operation then with the filter screen reinstall.
