Description
Technical field
The utility model belongs to water treatment field, relates to a kind of strainer valve.
Background technology
Strainer valve claims filter again, is widely used in the industrial production filtration to medium.Strainer valve is to use hydraulic control valve and the accurate prerequisite filter plant of susceptible to plugging engineering goods, is indispensable a kind of device in the pipeline of pumped (conveying) medium.Strainer valve is installed on the entrance point of equipment such as hydraulic control valve, pressure-reducing valve, relief valve, Valve for keeping constant water level usually, is used for eliminating the impurity in the medium, prevents granular impurity admission passage, results in blockage, with the equipment on the protection pipeline.When need cleaning,, reload after the processing and get final product as long as dismountable filter cylinder is taken out.Therefore, operation and maintenance is very convenient.The structure that adopts ring flange usually that is connected of cartridge filter and valve body to satisfy the needs that industrial production medium high pressure is carried, is difficult for producing and leaks.
In daily life, strainer valve can be used in the impurity of removing in the running water equally, improves the water quality of domestic water.Those skilled in the art have improved strainer valve according to actual service conditions, for example, and Chinese patent [patent No. ZL02265825.4; Authorize publication number CN2568273Y] disclosed a kind of strainer valve, comprise that one has the body of water-purifying cavity, the water inlet pipe that links to each other with body and outlet pipe, water inlet pipe and outlet pipe all communicate with water-purifying cavity, a lid that links and can shirk with body is arranged on the body, be provided with filter core in the water-purifying cavity, the inlet opening of crossing filter core communicates with water inlet pipe, and the apopore of crossing filter core communicates with outlet pipe.Crossing filter core can adopt to be threaded and link to each other with body.
Above-mentioned strainer valve structure is comparatively simple, but the filter core of crossing that is positioned at valve body departs from the installation site easily under the effect of current, and the filter effect of strainer valve is descended, even entirely ineffective.Adopt and be threaded if cross filter core, need screw connection structure to be set crossing on the filter core, and the relevant position machining screw on body, make the strainer valve structure comparatively complicated, the cost height, and the dismounting of crossing filter core more bothers.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of simple in structure, the strainer valve of the reliable and easy accessibility in screen pack location.
The purpose of this utility model can realize by following technical proposal: a kind of strainer valve, comprise valve body with water-purifying cavity, have the water inlet pipe and the outlet pipe that communicate with water-purifying cavity on the valve body, be removably connected with valve gap on the valve body, it is characterized in that, be provided with screen pack in a tubular form between described water inlet pipe and the water-purifying cavity, has support portion on the described valve gap for the screen pack location, described valve body offers the slot to make way relative with the location structure position, one end of described screen pack and location, support portion, the other end is resisted against the bottom of described slot to make way.
This strainer valve is applied to can carry out filtration treatment to medium in the lower pipeline of hydraulic pressure.Medium enters the inner chamber of screen pack from water inlet pipe, and enters water-purifying cavity by the gap of screen pack sidewall, and impurity is filtered the net retaining outside water-purifying cavity in this process, and is last, flows to outlet pipe through the medium that filters by water-purifying cavity.One end of screen pack and location, the support portion on the valve gap, and when mounted, the other end of screen pack is resisted against the bottom of slot to make way, and the location of screen pack is reliable; During dismounting, screen pack breaks away from valve gap and valve body, then again it is applied outside axial force it is separated with valve gap, and it is convenient to change.
In above-mentioned strainer valve, described support portion comprises the boss that is connected in the valve gap bottom, and the bottom of described screen pack is socketed on the described boss.Boss and valve gap adopt integral molding, and be easy to process, and can make screen pack and valve gap radial location.
In above-mentioned strainer valve, described valve gap and valve body are by being threaded.Dismounting is comparatively convenient.
In above-mentioned strainer valve, be provided with sealing ring between described valve gap and the valve body.Improve the sealing effectiveness of valve body and valve gap, make medium be difficult for leaking.
In above-mentioned strainer valve, described outlet pipe has external screw thread.
In above-mentioned strainer valve, described outlet pipe has internal thread.
Both can machining internal thread on the outlet pipe of this strainer valve, also can threading, with being connected of pipeline, improve the versatility of equipment in convenient actual the use.
Compared with prior art, an end of the screen pack of this strainer valve and location, the support portion on the valve gap, the other end is resisted against the bottom of slot to make way, and the location of screen pack is reliable, and changes conveniently; Both can machining internal thread on the outlet pipe, also can threading, versatility is good.
