Description

The dual-purpose non-return filtering valve of integral type

Technical field

The utility model relates to a kind of valve, is specifically related to only valve a kind of time.

Background technique

Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in pipeline from flowing backwards, and is widely used at the pipe-line system safety check.But at present common its function of safety check is comparatively single on the market, except preventing that medium from flowing backwards, can't play control and the switch of controlling water flow in pipeline, often in the pipeline installation process, need to coordinate other valves of installation, and the connection of a plurality of valves not only makes the pipeline installation process too loaded down with trivial details, and the drawbacks such as medium leakage easily occur, affect whole sealing.In addition, circulating liquid in the water channel pipeline, be subject to the impact of metallic conduit due to environment or in transportation process, make in circulation medium and easily produce particulate contamination, and these impurity easily cause wearing and tearing to the valve in pipeline along with the medium all parts in pipeline that continues to flow, to sensitivity, the precision of the higher instruments such as water meter causes damage, reduce its working life, increase maintenance cost.

The model utility content

The purpose of this utility model is, provides a kind of integral type dual-purpose non-return filtering valve, solves above technical problem.

The technical problem that the utility model solves can realize by the following technical solutions:

The dual-purpose non-return filtering valve of integral type, comprise a check valve body, described check valve body comprises a valve body, a flap, it is characterized in that, also comprise a ball valve, described ball valve comprises a ball valve body, and described ball valve body connects the water outlet of described valve body, and described ball valve body and described valve body connect as one.

When current are arranged through described check valve body, the water flow impact pressure that described flap is subject to current is rushed open, current pour in described valve body fast, but single safety check can't play the effect of regulating water flow, if merely safety check is connected with ball valve, can exist and connect crack, and current moments is while pouring described check valve body, air pressure moment increasing in described valve body, easily make water leak from connect crack, and described ball valve and described safety check are connected as one, not only increase bulk strength, and can improve overall tightness, and counterflow-preventing and the function of controlling water flow can be united two into one, when pipe-line system connects, simplify and install.

Described check valve body also comprises a connecting rod, the upper end of described connecting rod and described valve interior wall chain connection, and the bottom of described connecting rod connects described flap.

Described flap is positioned at described valve body, and described flap right-to-left is obliquely installed.When the described flap of water impact, described flap is obliquely installed to the lifting surface area that can increase described flap, the current of being convenient to following current can easily be washed described flap open and enter in described valve body.

Also comprise a filter screen device, described filter screen device is between the spool of described flap and described ball valve.After in current flow to described valve body, described filter screen device is filtered the current that flow through, and removes the impurity in current, makes the current that flow out described check valve body more clean.

Described filter screen device comprises that at least one filter screen, holds the impurity receiving cavity of impurity, and described impurity receiving cavity is positioned at the below of described valve body, and described impurity receiving cavity connects described valve body;

Described filter screen is positioned at described valve body, and described filter screen right-to-left tilts, and described impurity receiving cavity is positioned at the below of described filter screen.After having impurity to be filtered out by described filter screen, impurity will be under the style of work of gravity and bourn acting force, directly drops into or holds cavity along the described impurity that slips into of filter screen downwards.

The downside that described impurity holds cavity is provided with a valve gap, the described valve gap described impurity receiving cavity that removably connects.Hold impurities accumulation in cavity to a certain extent the time with the described impurity of box lunch, open described valve gap, described impurity is held to cavity and cleared up.

Be provided with a permanent magnet in described valve gap, described permanent magnet and valve gap removably connect.When in the current in pipe-line system, iron filings class impurity is more, can in described valve gap, connect described permanent magnet, suction-operated by described permanent magnet, strengthen the filtration of described filter screen device to iron filings class impurity, and after the long-term use of described filter screen, the impurities accumulation on described filter screen is dirt, and the installation of described permanent magnet can be played certain de-sludging effect to described filter screen, when not needing, also described permanent magnet can be taken out in described valve gap.

Described flap is provided with at least one seal ring; the o type circle that described seal ring can adopt quality of rubber materials to make; when the setting of described seal ring can strengthen the sealing between described flap and described valve body; also can play the effect of protection flap, alleviate the violent shock of flap between switching process and described valve body.

Beneficial effect: owing to adopting technique scheme, the utility model is set up ball valve returning on the basis of valve only, makes back to stop valve and not only can play the effect of counterflow-preventing, and controllable flow flow again, overall structure is simple and practical.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.

With reference to Fig. 1, the dual-purpose non-return filtering valve of integral type, comprise a check valve body 1, check valve body 1 comprises a valve body 11, a flap 12, also comprises a ball valve 2, and ball valve 2 comprises a ball valve body 21, ball valve body 21 connects the water outlet of valve body 11, and ball valve body 21 connects as one with valve body 11.When current are arranged through check valve body 1, the water flow impact pressure that flap 12 is subject to current is rushed open, current pour in valve body 11 fast, but single safety check can't play the effect of regulating water flow, if merely safety check is connected with ball valve, can exist and connect crack, and current moments is while pouring check valve body, air pressure moment increasing in valve body, easily make water leak from connect crack, and ball valve 2 and safety check are connected as one, not only increase bulk strength, and can improve overall tightness, and counterflow-preventing and the function of controlling water flow can be united two into one, when pipe-line system connects, simplify and install.
