Description

A kind of tee ball valve

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of valve, particularly a kind of tee ball valve.

Background technique

Valve is widely used in industry and daily life, and it is to be used for making the flowing medium of pipe-line system to flow or to stop, and can control the device of its flow.

Existing valve is loaded on the spool in the valve body usually by a two-way valve body, is connected the valve rod on the spool, and the handle that is connected on the valve rod is formed.In the time of need operating valve, pull handle, can drive valve core rotation by valve rod.Just can reach the purpose of pilot line system inner fluid medium after the valve core rotation.

Obviously, though above-mentioned valve mechanism is fairly simple, function is more single, that is to say, it can only lead to hot water or cold water.When if desired hot water being mixed the water that reaches required temperature mutually with cold water, above-mentioned valve just is difficult to reach this purpose.

Existing other valve also exists similar problem.

Summary of the invention

The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of simple in structure, tee ball valve that applicability is higher is provided.

The purpose of this utility model can realize by following technical proposal: a kind of tee ball valve, comprise valve body, spool, valve rod and handle, have intake tunnel and exhalant canal on the described valve body, be provided with spool in the valve body between intake tunnel and the exhalant canal, the inner of valve rod links to each other with spool, the outer end of valve rod passes valve body and links to each other with handle, it is characterized in that, the quantity of described intake tunnel is two, and the import of these two intake tunnels all is connected with the spool place, be respectively equipped with a spool in described two intake tunnels, all be connected with valve rod and handle on each spool.

In this tee ball valve, two intake tunnels can feed different flowing mediums respectively, as: cold water, hot water.Make the valve core rotation at each intake tunnel place, just can control the feeding amount of this intake tunnel place flowing medium or make its switching.

For example, when needing cold water, the spool at the intake tunnel place of hot water closed get final product.On the contrary, when needing hot water, the spool at the intake tunnel place of cold water closed get final product.According to actual conditions, when needing the water of different water temperatures, control the opening degree of two intake tunnel place spools and can realize.

In above-mentioned tee ball valve, two intake tunnels form one L shapedly in the described valve body, and the entrance point of above-mentioned exhalant canal is connected with L shaped corner.Such structure makes two intake tunnel places all have an amount of and impartial flowing medium and enters exhalant canal that certainly, above-mentioned situation is under the prerequisite that the spool opening degree equates in intake tunnel and exhalant canal.

In above-mentioned tee ball valve, be equipped with the limit structure that can limit the handle hunting range between described each handle and the valve body.

Can limit the oscillator arc of handle by this limit structure, that is to say, make that when handle was rocked to two limit position, spool was in the state of standard-sized sheet or full cut-off all the time.

In above-mentioned tee ball valve, described limit structure is the shoulder block that protrudes on the retaining edge of protruding on the handle and the valve body.

As another situation, in above-mentioned tee ball valve, described limit structure is the retaining edge of protruding on the shoulder block that protrudes on the handle and the valve body.

After handle is pulled, just can limit the oscillator arc of handle by retaining edge and shoulder block.Thereby limit the rotation radian of spool accordingly.

Compared with prior art, this tee ball valve is owing to only be made up of valve body, spool, valve rod and handle etc., therefore, it simple in structure, cost is lower.

Simultaneously, two intake tunnels can feed different flowing mediums, and can realize that by controlling two handles the exhalant canal place discharges the flowing medium of different mixing proportion.Obviously, its applicability is higher.

Description of drawings

Fig. 1 is the form structure schematic representation of this tee ball valve.

Fig. 2 is along the A-A sectional structure schematic representation among Fig. 1.

Among the figure, 1, valve body; 1a, intake tunnel; 1b, exhalant canal; 1c, shoulder block; 2, spool; 3, valve rod; 4, handle; 4a, retaining edge.

Embodiment

As shown in Figure 1, this tee ball valve comprises valve body 1, spool 2, valve rod 3 and handle 4, and the inside of valve body 1 is cavity, that is to say to have two intake tunnel 1a and an exhalant canal 1b on the valve body 1.

It is one L shaped that two intake tunnel 1a form, and the entrance point of exhalant canal 1b is communicated with the L shaped corner of two intake tunnel 1a.

As depicted in figs. 1 and 2, the quantity of spool 2, valve rod 3 and handle 4 is two.One of them spool 2 is loaded in one of them intake tunnel 1a, and the inner of valve rod 3 and spool 2 are connected, and the outer end of valve rod 3 passes valve body 1, and handle 4 just is connected in the outer end of valve rod 3.Another one spool 2 is loaded in the another one intake tunnel 1a, and the Placement of valve rod 3, handle 4 is identical, at this Ao Shu no longer.

Be provided with limit structure between above-mentioned two handles 4 and the valve body 1, limit structure can limit the hunting range of handle 4.In the present embodiment, limit structure is to be located at retaining on the handle 4 along 4a, and retaining protrudes from handle 4 and is located at shoulder block 1c on the valve body 1 along 4a, the protruding valve body 1 that is in of shoulder block 1c, and shoulder block 1c just can contact along 4a with keeping off in handle 4 swing process.

One of them intake tunnel 1a of this tee ball valve is connected with a cold water pipeline, and another one intake tunnel 1a is connected with a hot water pipe.Exhalant canal 1b is connected with rising pipe or water outlet.

Pull handle 4, after rotating by valve rod 3 drive spools 2, the flowing medium in the intake tunnel 1a will enter exhalant canal 1b place by spool 2, is discharged by exhalant canal 1b at last.

As depicted in figs. 1 and 2, when two spools 2 were in closed condition simultaneously, whole tee ball valve was in closed condition, and flowing medium can't pass through this tee ball valve.When two spools 2 were in full-gear simultaneously, whole tee ball valve was in opening state, and flowing medium is discharged by exhalant canal 1b place at last by this tee ball valve.According to actual conditions, when spool 2 opening degrees at two intake tunnel 1a places were inconsistent, the water of being discharged by exhalant canal 1b place promptly was the water of higher temperature or lower temperature.
