Description

Fluid guiding relief valve

The utility model relates to a kind of fluid guiding relief valve, particularly relates to a kind of member fluid guiding relief valve simple, easy to use.

Fluid guiding relief valve in the past is owing to have a plurality of valve body piece, and the cooperation between each part, assembling complexity, so the mode of production of fluid guiding relief valve is mostly in the artificial combination mode, except required manually how, also have the product configurations complexity, can't automatic production, break down easily, shortcoming such as cost height.

The novel purpose of this use is to provide that a kind of member is simple, assembling easily, rate of fault is low, but and the automation fluid guiding relief valve producing in a large number, reduce production costs.

Of the present utility model being characterised in that: this fluid guiding relief valve is to have the inlet of person in charge hollow valve seat both sides and be responsible for outlet, described person in charge's inlet and person in charge's outlet connect for tubing respectively, and the elastic valve body of an inner hollow is contained in the valve seat, and there is a triplate line to be communicated with described person in charge out respectively, inlet and elastic valve body, two mouthfuls of control fluids that utilize triplate line are in the elastic valve body pressure inside, the bullet valve body is shunk, the action of expanding, and the pore size between control elastic valve body outer wall and valve base inner wall, make and be responsible for inlet and be responsible for outlet interior fluid flow or blocking-up, make the utility model just have the effect of relief valve with a valve seat and elastic valve body.

Below by most preferred embodiment and accompanying drawing fluid guiding relief valve of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the generalized section of the utility model preferred embodiment.

Fig. 2 is the schematic perspective view of the utility model preferred embodiment.

Fig. 3 is the schematic side view of the utility model preferred embodiment.

Fig. 4 is the open schematic representation of valve body in the utility model preferred embodiment.

Fig. 5 be in the utility model preferred embodiment valve body close schematic representation.

As shown in Figure 1, 2, 3, the fluid of the utility model preferred embodiment guiding relief valve comprises a valve seat 10,

elastic valve body

20,31,32 and triplate lines 40 of upper and lower capping.

Valve seat 10 has one and roughly is criss-cross hollow tube 11, and body 11 both sides have the outlet of person in charge 12 and person in charge's inlet 13 respectively, is responsible for outlet 12 and is respectively equipped with a branch inflow entrance 14 and a shunting outlet 15 with person in charge's inlet 13 apical ring sides.

Elastic valve body 20 is contained in body 11 inwalls of valve seat 10, have telescopic resilience and inner hollow, the upper and lower ring edge of elastic valve body 20 extends respectively and is provided with a

flange

21,22,

flange

21,22 retainings lean against body 11 tops, base ring edge, have the gap with body 11 inwalls when elastic valve body 20 shrinks, then block after the expansion to be responsible for outlet 12 and to be responsible for and enter the mouth 13.

Upper and

lower capping

31,32 difference shutoff are in body 11 tops, bottom surface, and press solidly elastic valve body 20 top,

bottom flange

21,22, make elastic valve body 20 location, and prevent that fluid from being oozed out by top, the base ring edge of elastic valve body 20, and upper cover 31 end faces have a fluid guiding inlet 33 in addition, and fluid guiding inlet 33 can be guided by shunting outlet 15 fluids that enter triplate line 40 and be entered in the elastic valve body 20.

As shown in Figure 3, triplate line 40 connects shunting outlet 15, fluid guiding inlet 33 respectively and divides inflow entrance 14, pipeline near shunting outlet 15 places is provided with a safety check 41, in case the fluid stopping body refluxes, then be provided with a two-port valve 42 near the pipeline that divides inflow entrance 14 places, with the circulation of controlling liquid.

Above-mentioned is the structure of each assembly of the utility model, the explanation of feature and relevant position, its assembling situation is according to the relevant position combine and assemble, cooperate Fig. 4, shown in 5, when two-port valve 42 is closed, the fluid of script circulation in triplate line 40, the influence that closed by two-port valve 42, divide inflow entrance 14 and can't flow to by shunting outlet 15, but, this moment, fluid was still constantly flowed in the triplate line 40 by shunting outlet 15, and the fluid that flows into triplate line 40 is subjected to the effect of safety check 41, be responsible in the inlet 13 and can't be back to, therefore, the fluid that is obstructed then is guided by fluid guiding inlet 33 and enters in the elastic valve body 20, makes these elastic valve body 20 inside constantly pour in a large amount of fluids, and the more and more big and Xiang Huanzhou expansion of the pressure that these elastic valve body 20 inwalls are born, expand, the outer wall of elastic valve body 20 is touched be against valve seat 10 inwalls, the person in charge of blocking-up valve seat 10 both sides enters the mouth 13, be responsible for 12 fluid flows of outlet.When two-port valve 42 is opened, this fluid then is circulation status, flow to branch inflow entrance 14 by shunting outlet 15, go forward side by side and export 12 into the person in charge, at this moment, the hydraulic pressure of elastic valve body 20 inside obtains to discharge, and because of tool elastic-restoring force own, discharge fluid and inwardly shrink, make elastic valve body 20 reinstatements and form the gap with valve seat 10 inwalls, the fluid that valve seat 10 is responsible for inlet 13 then flow to along the gap of elastic valve body 20 outer walls and valve seat 10 inwalls and is responsible for outlet 12, and therefore, the utility model just can be controlled the circulation or the blocking-up of fluid with valve seat 10 and elastic valve body 20.

Advantage of the present utility model and effect explanation as back:

One, the utility model is with the circulation or the blocking-up of simple valve seat 10, elastic valve body 20, capping 31,32 and triplate line 40 control fluids, and not only member is simple, and combination, assembling are easily, and degree of adaptability height between each member, rate of fault is low, so, but automatic production reduces production costs.

Two, elastic valve body 20 forms for the rubber-like material is integrally manufactured, and external shape can be decided according to the shape of valve seat 10 inside, so the utility model can be widely used on the various fluid guide devices, with control fluid flow or blocking-up.

Three, fluid flow or blocking-up are by elastic valve body 20 controls, the pressure that then is limited by fluid is fully shunk in the expansion of elastic valve body 20, therefore, fluid flow or blocking-up in the pressure control valve seat 10 of the complete mat fluid of the utility model itself, irrelevant fully with the flow or the pressure of sluice gate fluid, the user has increased the convenience of using as long as switch two-port valve 42 is just passable.

In sum, fluid of the present utility model guiding relief valve except having simple structure, easy to use, the effect that is difficult for fault, but and have the product automatic production, advantage such as reduce production costs.
