Description

Has the drain valve of emergency function

Technical field

A kind of valve is the utility model is related to, more particularly, it relates to a kind of drain valve for having emergency function.

Background technology

In the prior art, hydrophobic valve arrangement is complex, generally comprises valve seat, flap and multiple bonnets, adopts between them The mode being arranged with multilayer, processing are more complicated.And existing drain valve when in use typically jacks up internal flap by water level, So as to realize draining, once water level, which occurs, to jack up flap, then drain valve is ineffective, now, can only enter drain valve Row promptly unloads divided by draining, influences being normally carried out for production work.

Utility model content

For overcome the deficiencies in the prior art, the purpose of this utility model be to provide it is a kind of simple in construction, and can be artificial Control the drain valve of the tool emergency function of flap position.

To solve the above problems, technical scheme is as follows used by the utility model：

A kind of drain valve for having emergency function, including valve body, valve seat, flap, bonnet and traction component, the valve body upper end Storage tank is offered, the section of the valve seat is inverted T-type structure, and the water inlet connected with the osculum of valve body is opened up on the valve seat Hole and the apopore connected with the outlet pipe of valve body, the valve seat are set in the bottom of bonnet, structure between the valve seat and bonnet Into accommodating cavity, the flap is arranged in accommodating cavity, and the bonnet is set in storage tank, and the traction component includes running through valve Cover and be slidably arranged on the draw bar in bonnet, and one end is connected to the one end of draw bar on the inside of bonnet, the other end The pull rope being connected with flap.

Preferably, the traction component also includes bail, the bail and the one end of draw bar on the outside of bonnet Connection.

Preferably, the pull rope is elastic threads.

Preferably, the valve seat is provided with guide rod close to bonnet side-walls, and the flap periphery is provided with and guide rod The notch to match.

Preferably, it is provided with elastic component between flap and the bonnet top.

Preferably, the elastic component is spring.

Preferably, the flap is provided with floating block close to the side of valve seat.

Preferably, the aperture of the inlet opening is not more than the aperture of apopore.

Compared with prior art, the beneficial effects of the utility model are：The utility model is by the way that valve seat and flap are set It is arranged in bonnet, then by bonnet in storage tank, that is, completes the assembling of whole drain valve, installation is simpler, reduces processing In the cycle, reduce the cost of processing；And single water space is formed between the valve seat of inverted T-type structure and single bonnet, will not Cause the resident of water, the more conducively abundant discharge of water, and be easy to clean；The setting of elastic component can ensure the smooth reset of flap, Ensure using effect；The setting of traction component, the normal use of drain valve is neither influenceed, in case of emergency, can also artificially be controlled Flap position processed, it is further ensured that the orderly progress of production work.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

As shown in figure 1, it is a kind of drain valve for having emergency function, including valve body 1, valve in the utility model preferred embodiment Seat 2, flap 3 and bonnet 4, the upper end of valve body 1 offer storage tank 11, and the section of valve seat 2 be inverted T-type structure, opened up on valve seat 2 and The inlet opening 100 of the osculum connection of valve body 1 and the apopore 200 connected with the outlet pipe of valve body 1, valve seat 2 are set in bonnet 4 Bottom, accommodating cavity 300 is formed between valve seat 2 and bonnet 4, flap 3 is arranged in accommodating cavity 300, and bonnet 4 is set in storage tank In 11.In use, by the osculum of valve body 1 to draining at inlet opening 100, when water level reaches to a certain degree, flap can be by Jack up, and because the position of apopore 200 is relatively low, flowing into the water of accommodating cavity 300 can thoroughly discharge.The utility model is by by valve Seat 2 and flap 3 are arranged in bonnet 4, then bonnet 4 is arranged in storage tank 11, that is, complete the hydrophobic of whole tool emergency function The assembling of valve, installation is simpler, reduces the process-cycle, reduces the cost of processing；And the valve seat 2 of inverted T-type structure is unnecessary Gushing out for water provides bigger accommodation space, is easy to the abundant discharge of water.

Specifically, as shown in Fig. 2 in order to ensure that the lifting of flap 3 is more smooth, it is unlikely to run-off the straight and can not makes With valve seat 2 is provided with guide rod 21 close to the side-walls of bonnet 4, and the periphery of flap 3 is provided with the notch to match with guide rod 21 31, flap 3 realizes the normal lifting in accommodating cavity 300 by guide rod 21.

Flap 3 is smoothly returned to valve seat 2 after being reduced for guaranteed water level, and bullet is provided between flap 3 and the top of bonnet 4 Property part 5, elastic component 5 is preferably spring, springs back to flap 3 on valve seat 2 after water level reduction, inlet opening 100 is formed more preferably Sealing.

It should be understood that in order to offset lower pressure of the elastic component 5 to flap 3 to a certain extent, flap 3 is close to valve seat 2 Side be provided with floating block 32.When water level rises, it is possible to provide certain buoyancy, offset the lower pressure of elastic component 5.

In a detailed embodiment, the drain valve also includes being used for the traction component for lifting flap 3.The traction Component includes the draw bar 61 for running through bonnet 4 and being slidably arranged in bonnet 4, and one end is connected to draw bar 61 close to valve One end of the inner side of lid 4, the pull rope 62 that the other end is connected with flap 3.Usually in use, because pulling rope 62 is flexible material, The lifting of flap 3 is not influenceed；Under special circumstances, it is necessary to when flap 3 is lifted, by lifting draw bar 61, you can realize valve Valve 3 lifts, so as to facilitate the discharge of water at inlet opening 100.

Certainly, in order to facilitate the lifting of draw bar 61, the traction component also includes bail 63, bail 63 and traction One end connection of the bar 61 close to the outside of bonnet 4.

Specifically, in order to reduce influence of the pull rope 62 to flap 3, pull rope 62 is preferably elastic threads.

Further, the aperture of inlet opening 100 is not more than the aperture of apopore 200, is arranged such, can enter to greatest extent Row draining, ensure the efficiency of draining.

In another embodiment, as shown in figure 3, the drain valve also includes being used for the outlet pipe for preventing valve body 1 The non-return component 7 of refluence.Non-return component 7 is fixed in apopore 200, and non-return component 7 includes fixed part 71, is arranged on fixed part The supporting part 72 of 71 lower ends and the non-return flap 74 being arranged in supporting part 72, the aperture of fixed part 71 are less than the hole of supporting part 72 Footpath, the one end of non-return flap 74 are articulated in supporting part 72 by rotating shaft.Non-return flap 74 is washed open in draining by current, is not influenceed Draining；If extraneous water level is too high, non-return flap 74 will be closed at fixed part, avoid the generation of backflow phenomena.

Specifically, the limited block 73 of the slewing area of limitation non-return flap 74 is additionally provided with supporting part 72, it is ensured that non-return The moving region of flap 74, avoiding water from flowing through senior general, it is rushed to side, can not play a part of non-return.

In order to ensure better seal effect, non-return flap 74 is arcuate structure, so as to preferably be bonded opening for fixed part Mouthful, realize preferable sealing effectiveness.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims Within the scope of.
