Abstract
The utility model relates to a filter-type check valve for controlling the flow rate of engineering pipeline fluid. The check valve comprises a valve body which can be connected in series between fluid pipelines, a valve flap driven by a hand wheel lead screw is pressed and sealed above a valve opening between the inlet section and the outlet section of the valve body, a filter screen is arranged below the valve opening, the lower part of the valve body is provided with a filter screen assembly and disassembly hole, and a seal cover is pressed and sealed outside the filter screen assembly and disassembly hole. The filter-type check valve is characterized in that because a filter device is arranged in the valve body, the impurity-containing fluid medium of a pipeline system is effectively cleared, impurities can be prevented from staying on a sealing element, the closing performance of the valve is ensured, and normal use of the valve and other equipment in the pipeline system is ensured. The filter-type check valve is simple and compact in structure, good in sealing performance and very convenient to install and maintain, and is quick, convenient, safe and firm; and the service life of the pipelines and the valve is prolonged, the cost of an enterprise is reduced, and the production benefits are improved.
Description
Technical field
The utility model belongs to fluid flow regulation technology field, relates to a kind of filter-type stop valve that is used for Control Engineering pipeline fluid flow.
Background technique
At present in various pipe-line systems, usually cause pipeline to run well, severe patient even possibly cause the equipment in the pipe-line system to be destroyed because of the impurity that the pipeline inner fluid exists.Because the waterpower control type stop valve 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, this mode in application process, exist install complicated, connected element is many, be easy to generate leakages, volume is big, the inconvenient shortcomings such as (more unfavorable repairing), cost height of keeping in repair.
The model utility content
The purpose of the utility model is the problem that existing technology exists is solved, so provide a kind of simple in structure, easy to use, cost is low, can effectively remove the filter-type stop valve of the impurity in the pipeline fluid.
For realizing that the technical solution that the foregoing invention purpose adopts is such: the filter-type stop valve that is provided comprises a valve body that can be serially connected between fluid line; Press seal has a flap that is driven by the handwheel leading screw above the valve port between valve body inducer and the outlet section; Filter screen is housed below valve port; Have the filter screen handling hole in the bottom of valve body, outside the filter screen handling hole, be pressed with capping.
The realization of the technical solution of the utility model also is: but said flap is the taper piston flap that a bottom is provided with the compensation sealing valve pad.
Compare with existing like product, the utility model can effectively be removed the impurity in the pipe-line system medium, and then guarantee the normal use of miscellaneous equipment in valve and the pipe-line system owing in valve body, designed filter screen and taper piston flap.The utility model simple in structure, easy to installation and maintenance, cost is low, volume is little, in light weight, be convenient to the transportation, good seal performance; Compare with other valve and can save the lay day more than 60%; Reach not only quick and convenient but also safe firm good result, the usability and the working life that help improving pipe-line system, guarantee that valve and ducted equipment normally use; Remove the impurity in the pipe-line system medium, thereby reduce entreprise cost and improve productivity effect.
The suitable flowing medium of the utility model comprises multiple fluid 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.
Each number designation title is respectively in the accompanying drawing: 1-valve body, 2-capping, 3-filter screen, 4-nut bolt, 5-valve gap, 6-hold-down grid, 7-filler, 8-flap, 9-leading screw, 10-handwheel, 11-sealing gasket.
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 stop valve of the utility model is made up of valve body 1 and dismountable dirt filtrating equipment of being fitted in the valve body 1.Press seal has a flap 8 that is driven by handwheel leading screw 9 above the valve port between valve body 1 inducer and the outlet section; But this flap 8 is the taper piston flap that a bottom is provided with the compensation sealing valve pad; Advantage with favorable sealing property can be stopped the drop seepage, reaches 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 material of compensating type sealing valve pad, valve body is designed to plain edition, through-type, telescopic type and multiple structure such as combined.The dirt filtrating equipment of establishing in this filter-type stop valve comprises the filter screen 3 and a capping 2 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 3 during enforcement according to the actual demand of pipe-line system; Through the impurity in filter screen 3 filter mediums; Need only unload crossing capping 2 when removing contamination; Take out filter screen 3 and can remove foul,, load onto capping 2 again and just can accomplish the blowdown operation then with filter screen 3 reinstalls.
Claims (2)
1. filter-type stop valve; Comprise a valve body (1) that can be serially connected between fluid line; It is characterized in that the valve port top press seal between valve body (1) inducer and outlet section has a flap (8) that is driven by handwheel leading screw (9); Filter screen (3) is housed below valve port, has the filter screen handling hole, outside the filter screen handling hole, be pressed with capping (2) in the bottom of valve body (1).
