Description
Technical field
The utility model relates to a kind of ball valve, and more particularly, it relates to a kind of ball valve that can filter and have buffering.
Background technique
Ball valve is defined as in standard GB/T21465-2008 " valve term ": open-shut device (spheroid) is driven by valve rod, and the valve that rotates around the axis of valve rod.It has the action of 90-degree rotation ball valve, and faucet body is spheroid, manhole or passage is arranged by its axis.Utilize spheroid to realize the purpose of opening and closing around the axis half-twist of valve rod.Ball valve is mainly used to make cut-out, distributes and change medium in pipeline flow direction, the ball valve optimum is made switch, cut-off valve uses, but recent development has become to make it to have throttling and control being widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel with ball valve of flow with ball valve design, occupy very important status open-shut device (spheroid) and driven by valve rod in national economy, and the valve that rotates around the axis of valve rod.Ball valve is simple in structure, good seal performance not only, and less, lightweight in certain inside nominal diameter scope inner volume, material consumption is few, installation dimension is little, and driving moment is little, and is easy and simple to handle, easily realize fast opening and closing, is in recent ten years one of valve kind with fastest developing speed.
At present, (application number is that 201010268102.3 Chinese patent discloses a kind of Filtering ball valve) on market, it comprises valve body, valve ball, valve rod; Described valve body is the straighttube-type valve body, and valve body is provided with arm, and arm and valve body have angle, and angle one side of arm and valve body is provided with valve seat, is provided with valve ball in valve seat, is sealing surface between valve ball and valve seat; The valve ball top is provided with valve rod, and valve gap is established at the valve rod top; Be provided with filter screen in arm, filter screen stretches into the inside of valve body; Rotary valve cover, valve gap drives valve ball by valve rod and moves up and down with respect to valve seat, realizes the keying of valve.Although this Filtering ball valve has possessed the effect of filtering, but consider that ball valve is when having liquid to flow through, it is constant that the flow velocity of liquid can one deck, each pressure, the size of impact force are all different, so the pressure that each filtrating equipment need to bear is also different, the filtrating equipment that does not possess cushioning effect is easily impaired, and the life-span is not long.
The model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of filter screen life-span long ball valve.
for achieving the above object, the utility model provides following technological scheme: a kind of ball valve, comprise valve body, spool and valve handle, be provided with fluid through-hole between entrance and outlet in described valve body, described valve body comprises left valve gap, right valve gap and middle body, left valve gap and right valve gap are fixedly connected on respectively middle body two ends, left valve gap and right valve gap and middle body joint are provided with seal ring, described spool is placed in body, being provided with through hole and valve body fluid through hole in spool connects, described left valve gap and right valve gap and middle body joint are provided with elastomer seal, Sealing is provided with a shock absorber near the gateway end, be fixedly connected with filter screen between shock absorber and elastomer seal.
By adopting technique scheme; be fixedly connected with filtration between described elastomer seal and shock absorber; when liquid flows through; give pressure of filter screen and impact force; because in the middle of filter screen is placed in; so when impact force is impacted; elastomer seal can be given him an elastic force, has played certain buffering, when another side impacts; shock absorber has been given a cushion effect; the effect of a buffering can be played in both sides like this, has well protected filter screen not fragile, when also making liquid flow through fluid through-hole; foreign material in can filter liquide have guaranteed liquid quality.
The utility model further is set to: described elastomer seal is elastic seal ring.
By adopting technique scheme, adopt elastic seal ring, not only itself play a seal action, by the cushion effect that the shock absorber of an end is given, add the elasticity of self, just can play further sealing.
The utility model further is set to: described shock absorber is damping spring.
By adopting technique scheme, shock absorber is set to damping spring, and damping spring own has good cushioning effect, and low price, has reduced cost of production.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment's ball valve.
Fig. 2 is the partial enlarged drawing of the utility model embodiment's ball valve.
Description of drawings in figure: 1, left valve seat; 2, filter screen; 3, spool; 4, right valve seat; 5, damping spring; 6, elastic seal ring; 7, fluid through-hole; 8, valve rod; 9, middle body.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
a kind of ball valve, comprise valve body, spool 3 and valve handle 8, be provided with fluid through-hole 7 between entrance and outlet in described valve body, described valve body comprises left valve gap 1, right valve gap 4 and middle body 9, left valve gap 1 and right valve gap 4 are fixedly connected on respectively middle body 9 two ends, left valve gap 1 and right valve gap 4 is provided with seal ring with middle body 9 joints, it is characterized in that: described spool 3 is placed in body 9, be provided with through hole and 7 perforations of valve body fluid through hole in spool 3, described left valve gap 1 and right valve gap 4 is provided with elastomer seal with middle body 9 joints, Sealing is provided with a shock absorber by the gateway end, be fixedly connected with filter screen 2 between shock absorber and elastomer seal.Described elastomer seal is elastic seal ring 6, and shock absorber is damping spring 5.When left valve gap 1 is fixedly connected with middle body 9 one ends, right valve gap 4 is fixedly connected with middle body 9 the other ends, spool 3 is arranged in middle body 9 around valve handle 8 axis rotations, when rotary spool 3, when the through hole in spool 3 communicates with fluid through-hole 7, valve is in opening state, liquid goes out to flow in valve from water inlet, liquid filters for the first time through filter screen 2, when liquid passes with impact force, be flushed on filter screen 2, elastic seal ring 6 is being fixedly connected with filter screen 2, and elastic seal ring 6 is given 2 one power opposite with impact force of filter screen, makes filter screen 2 obtain a well buffering.When liquid passes through middle body 9 through hole, give 2 one impact forces of filter screen of opposite side, the damping spring 5 that filter screen 2 is fixedly connected with is given 2 one cushion effects of filter screen, reduces impact force.By such setting, make valve have filter liquide impurity function, by filter screen 2 being arranged in the middle of elastomer seal and damping spring 5, guaranteed the working life of filter screen 2.
Easily damage problem because the utility model example has solved the valve filtering net, improved the working life of filter screen.
The above is only preferred embodiment of the present utility model, and in order to limit the utility model, those skilled in the art does not carry out common variation and replace should being included in protection domain of the present utility model in the technical solutions of the utility model scope.
