Abstract

The utility model discloses a medium purifying-type ball valve which comprises a valve body, a ball sealer, a handle and a valve rod, wherein the ball sealer is connected with the handle through the valve rod, and further comprises a filter screen and a draining port, wherein the filter screen is arranged on the flow passage port of the ball sealer, the draining port is arranged on the side wall valve body opposite to the ball sealer, and the draining port is provided with an end cap. The medium purifying-type ball valve provided by the utility model has simple structure and smart design, not only can be used as a normal ball valve, but also can filter sundries in the medium, realizes the combined function of a common ball valve and a filter, has small installing space, simple and convenient assembly and replacing and flexible operation.

Description

A kind of dense medium purifica tion type ball valve

Technical field

The utility model relates to a kind of dense medium purifica tion type ball valve.

Background technique

In urban pipe network and industrial water supply system, usually there is impurity owing in the fluid; can cause the terminal turbidity test that supply water to meet the demands; be generally protection watering equipment safe in utilization and occasion that the convection cell turbidity test are had relatively high expectations; filtrating equipment just need be installed to reach the effect of purifying media in pipeline; use general filter to come impurity in the filter medium at present in a large number in pipeline; simultaneously also need the installation and control main valve as last at terminal use's watering equipment; products such as modulating valve; more complicated is installed on the one hand; require the mounting point bigger simultaneously; pipe leakage point increases, and installation cost is also than higher.

The model utility content

The utility model has overcome shortcoming of the prior art, provide a kind of simple in structure, design dense medium purifica tion type ball valve cleverly, both having can be used as ball valve normally uses, foreign material in simultaneously again can filter medium, realized the function of these two kinds of valve combination of general ball valve and filter, installing space is little, it is simple and convenient to install and change, flexible operation.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of dense medium purifica tion type ball valve, comprise valve body, ball sealer, handle, valve rod filter screen and sewage draining exit, described ball sealer is connected with handle by valve rod, described filter screen is arranged on the runner mouth of ball sealer, described sewage draining exit be arranged on ball sealer over against the sidewall valve body on, described sewage draining exit is provided with end cap.

Improved, described end cap is provided with transparent visual windows; Can observe at any time whether abnormal conditions are arranged in the sewage draining exit, in time find cleaning in time.

Preferably, described sewage draining exit bore is greater than the bore of filter screen; Being convenient to filter screen takes out.

Preferably, be provided with draw-in groove in the described ball sealer, described filter screen is fastened in the draw-in groove of ball sealer by snap ring; After draw-in groove is set, snap ring can be effectively fixing filter screen.

Preferably, described filter screen can be arranged to U type, spherical, plane according to usage requirement; Select fully impurity screening of suitable filter screen under the different situations.

Preferably, described filter screen adopts corrosion resistant plate to be stamped to form; The filter screen that is stamped to form is durable.

Compared with prior art, the utility model has the advantages that: provide a kind of simple in structure, design dense medium purifica tion type ball valve cleverly, both having can be used as ball valve normally uses, foreign material in simultaneously again can filter medium, realized the function of these two kinds of valve combination of general ball valve and filter, installing space is little, it is simple and convenient to install and change, flexible operation.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a kind of dense medium purifica tion type of the utility model ball-valve structure schematic representation;

Fig. 2 is a kind of dense medium purifica tion type of the utility model ball valve half sectional view;

Fig. 3 is a kind of dense medium purifica tion type of the utility model ball valve filter screen structure schematic representation.

Embodiment

As Fig. 1, Fig. 2, Fig. 3 is an embodiment of a kind of dense medium purifica tion type of the utility model ball valve, comprise valve body 1, ball sealer 2, handle 3 and valve rod 4, described ball sealer 2 is connected with handle 3 by valve rod 4, also comprise filter screen 5 and sewage draining exit 6, described filter screen 5 is arranged on the runner mouth of ball sealer 2, described sewage draining exit 6 be arranged on ball sealer 2 over against sidewall valve body 1 on, described sewage draining exit 6 is provided with end cap 9, being provided with end cap can cover the sewage draining exit that opens wide, avoid under the situation of not using sewage draining exit, preventing that dirt from entering polluted water or stopping up sewage draining exit, described end cap 9 is provided with transparent visual windows, can observe at any time whether abnormal conditions are arranged in the sewage draining exit, in time find cleaning in time, described sewage draining exit 6 bores are greater than the bore of filter screen 5, being convenient to filter screen takes out, be provided with draw-in groove 8 in the described ball sealer 2, described filter screen 5 is fastened in the draw-in groove 8 of ball sealer by snap ring 7, after draw-in groove is set, snap ring can be effectively fixing filter screen, described filter screen 5 can be arranged to spherical according to usage requirement, can also be arranged to U type and plane according to usage requirement, in the ordinary course of things, the spherical filter screen can be best make contaminant filter, described filter screen adopts stainless steel to be stamped to form, and the filter screen that is stamped to form is durable.

Medium is to be flowed out by water outlet 11 from the through hole of water intake 10 by ball valve.When medium enters valve seal ball 2 through holes from water intake 10, impurity in the medium can be filtered by filter screen 5, when the more needs of impurity on the filter screen 5 clean, handle 3 revolved turn 90 degrees, make ball valve be in closed condition, ball sealer 2 lead to the hole site are rotated to over against sewage draining exit 6 places, this moment, ball valve was in closed condition, medium does not circulate, and uses clasp forceps can easily take out snap ring 7 and filter screen 5, filter screen 5 cleanings is totally reinstalled get final product.

In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
