Abstract

The utility model discloses a filtering valve with the function of stopping water, which comprises a water inlet valve and a water outlet valve. A receiving groove of the valve is provided with a screw cover and a nut which are connected in a sealed way; a filtering net is arranged between the screw cover and the nut; a plunger pushed by a spring is provided with an O-shaped sealing ring which forms an inosculated water stopping structure with an inner shoulder of the nut. The utility model can be either positioned at any position of an water inlet and an water outlet of a pipeline and remove the ordure by taking out the filtering net after dismounting the screw cover, or arranged between the water inlet and a water tap and remove the ordure directly; furthermore, the water tap can be changed; the two methods are performed in the condition of not cutting the water supply, thereby preventing the trouble of closing a general valve. The utility model can filter and remove the impurities at any time, thereby ensuring the water quality and being good for health of human body.

Description

Strainer valve with sealing function

Technical field

The utility model relates to a kind of valve, especially a kind of valve that had not only had the sealing function but also had filtering function.

Background technology

Strainer valve is a kind of a kind of valve that plays filtering water in the pipeline that is connected on.In our daily life, the application of running water is quite universal, because the water source, add the secondary pollution of running water in course of conveying, there are ducted various granular substances or the like as the corrosion of pipe interior or when the house decoration, make the water quality variation, or cause the wearing and tearing of line clogging or faucet valve core, it is not dead to cause tap to fit badly the pass, causes running water to waste, the consequence that occurs the casual Kingsoft of water even, misfortune and self be the neighbourhood even.The water quality difference directly influences our healthy, and in the current society economically developed, that living standard improves day by day, the quality of making the life better, increase water quality will be people's a eager desire.Therefore, people thirst for having a kind of can filter various impurity in the water source, not only can take out cleanings, prevent the valve of the excessive waste of running water at cleaning process but also energy sealing, " tap changes and repaiies the sealing valve " disclosed technology contents of the patent No. 92221222.8 is to be connected with valve body in pipeline, valve body connects tap, be provided with plunger in the valve body by spring push, the plunger bottom is provided with the water-stopping end that reaches the sealing purpose, and water-stopping end is provided with " O " RunddichtringO.This technology is in the water ring wearing and tearing or change the purpose that can reach sealing when repairing tap, has avoided the waste at water source, guarantees water quality but can't improve the water source.

Summary of the invention

Technical problem to be solved in the utility model is to avoid the defective of prior art and provide a kind of and can remove impurity in the pipeline, improve water quality and can reach the strainer valve with sealing function of automatic water stopping under the situation of not cutting off the water supply.

At technical problem to be solved in the utility model, the technical scheme of its solution is:

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the strainer valve with sealing function, comprise valve body with water inlet and delivery port, in valve body, be provided with the holding groove that connects with entery and delivery port, be provided with the blind nut and the nut that are tightly connected in the groove, plunger by spring push, and be located on the plunger with nut in shoulder form " O " RunddichtringO of water sealing structure, it is characterized in that being provided with screen pack between described blind nut and the nut, spring is located between valve body holding groove bottom land and the plunger bottom surface.

Compared with prior art, advantage of the present utility model is that strainer valve set up screen pack in valve body, can filter the various impurity in the water source, the cleaning water source is improved water quality have significant effect, the health that helps people, it is disassembly, cleaning at any time, owing to have the sealing function, disassembly, cleaning or all needn't close total valve when carrying out part exchanging, can not cause the excessive of running water yet and waste, can be arranged on the pipeline optional position and carry out dirt and filter, remove, also can be arranged on and carry out dirt between inlet channel and the tap and filter, eliminate and change.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is that Fig. 1 is at ducted scheme of installation.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Have the strainer valve (referring to Fig. 1-2) of sealing function, be installed in series between pipeline entery and delivery port optional position or water inlet and depotition cock.Comprise valve body 9 with water inlet and delivery port, this valve body have one with advance, the holding groove that delivery port connects, this groove is step-like endoporus, non through hole, one section is processed with internal thread in the middle of the endoporus, respectively with blind nut 1, nut 4 sealings are spirally connected, seal with " O " type circle 2 and plain washer 5 respectively on the faying face, plunger 6 tops are by the movable fit of blind nut, it passes from nut bore, be embedded with " O " type circle 7 in the annular groove of bottom, after coincideing, the interior shoulder of this " O " type circle and nut promptly forms water sealing structure with sealing function, spring 8 is located between valve body 9 holding groove bottom lands and plunger 6 bottom surfaces, is provided with screen pack 3 between blind nut and nut, and impurity screening is guaranteed the water source quality.

Generally, water inlet communicates with delivery port, and plunger makes spring be in compressive state because of the pressurization function of blind nut, and " O " type circle breaks away from shoulder in the nut, and it is that pipeline is opened that water sealing structure is opened.

This strainer valve can be installed between the entery and delivery port pipeline or be installed between water inlet and the depotition cock, when being installed in pipeline entery and delivery port optional position, as cleaning dirt, as long as the blind nut on top is backed out, plunger in the middle of being positioned at moves upward under the spring force function, " O " RunddichtringO on it is tightly coincide to be takeed in nut, reach and cut off current automatic water stopping purpose, can take out screen pack easily and clean this moment, reinstall then, tighten blind nut, plunger moves downward under the function of blind nut, and pipeline reopens.

When strainer valve is installed between water inlet and the depotition cock, equally can be under the situation of not cutting off the water supply by the operation blind nut, finish the cleaning of screen pack and change the task of tap.The utility model is installed simple, simple operation.

Claims

1. strainer valve with sealing function, comprise valve body (9) with water inlet and delivery port, in valve body, be provided with the holding groove that connects with entery and delivery port, be provided with the blind nut (1) and the nut (4) that are tightly connected in the groove, plunger (6) by spring (8) pushing tow, and be located on the plunger with nut in shoulder form " O " RunddichtringO (7) of water sealing structure, it is characterized in that being provided with between described blind nut and the nut screen pack (3), spring (8) is located between valve body (9) holding groove bottom land and plunger (6) bottom surface.
