Abstract
The utility model provides a tubular valve. The tubular valve has no handle and takes the rotation of a valve body as an opening and closing method of the valve. The tubular valve is composed of an input pipe, an output pipe and the valve body. The valve body is connect in parallel with a valve core sleeve in the valve body through the inner screw threads of a rotary pipe which is one part of the valve body. One end of the valve core sleeve is provided with a valve core, and the other end of the valve core sleeve is connected in parallel with the output pipe through a rotation stopping cushion. When the valve body forwards rotates, the rotary pipe drives the valve core sleeve to go forwards, and the valve is closed. When the valve body backwards rotates, the rotary pipe drives the valve core sleeve to retreat, and the valve is opened.
Description
The said valve of the present invention is a kind of liquid valve.Particularly a kind of no handle is with the rotation of valve body self Tube-like valve as opening/shutting mode.
Existing Liquid valve is called General valve, and wherein great majority are water valve.Ball valve for example, it partly is made up of valve body, handle, spool.Come opening/shutting valve by operation of vertical in the handle of pipeline, itself maintains static valve body.Overall volume is bigger, and it is big to take up room, and operating difficulties when especially needing one hand to hold the valve opening/shutting valve, valve body are foundry goods, process comparatively coarse, not attractive in appearance.The structure recess is arranged below the ball float, easy contamination, easy cleaning is not difficult for accurate control flow rate, especially tiny flow quantity.
Purpose of the present invention is exactly the improvement product that proposes at these shortcomings.
It is such that technology of the present invention constitutes:
Form valve by supplying tube, output tube and valve body.The positive and reverse return of valve body itself transfers to the opening/shutting mode into valve.Valve body is covered thoroughly by coil and termination to be formed, and coil is by its internal thread and the parallel connection of the valve core housing of valve inner.One end of valve core housing is equipped with spool, and the other end is by only revolving the parallel connection with output tube of pad.When the dextrorotation valve body, coil drives that valve core housing is parallel to advance closure valve; During the derotation valve body, valve core housing retreats, the breakdown valve.
Simple structure of the present invention, number of parts is few, and is easy to process, can hold the valve operation by one hand during use, accurately controls tiny flow quantity.Because the valve internal structure is a straight-through type,, be easy to clean so there is not the contamination dead angle.The valve overall volume is little, and is exquisite attractive in appearance.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing of a kind of Tube-like valve of proposition according to the present invention.
Fig. 2 is the front view of Fig. 1 valve.
With reference to Fig. 1 and Fig. 2, constitute valve by supplying tube ［ 8 ］, output tube ［ 1 ］, valve body ［ A ］.Valve body ［ A ］ covers ［ 2 ］ thoroughly by coil ［ 5 ］ and termination and constitutes, and coil ［ 5 ］ is by its internal thread and the parallel connection of valve core housing ［ 6 ］.One end of valve core housing ［ 6 ］ is equipped with spool ［ 7 ］, and the other end is by only revolving pad ［ 9 ］ and the parallel connection of output tube ［ 1 ］.During operation, with hand or instrument start-up rotary valve ［ A ］.During valve body ［ A ］ rotation, it is parallel mobile that coil ［ 5 ］ drives valve core housing ［ 6 ］ by its internal thread.When valve body ［ A ］ dextrorotation, valve core housing ［ 6 ］ advances, and drives spool ［ 7 ］ closure valve; During derotation valve body ［ A ］, valve core housing ［ 6 ］ retreats Open valve.
For the position of fixed valve body ［ A ］, supplying tube ［ 8 ］ and output tube ［ 1 ］ that end in valve body ［ A ］ can have boss.
In order to make valve core housing ［ 6 ］ translation in certain limit, be provided with and only revolve pad ［ 9 ］, the profile of only revolving pad ［ 9 ］ can be a double polarizing keys shape.
For valve body ［ A ］ can very be rotated deftly, can ball ［ 3 ］ be set in the boss outside and valve body ［ A ］ contacting point of supplying tube ［ 8 ］ and output tube ［ 1 ］; The inboard of two boss can be provided with seal ring ［ 4 ］, makes valve avoid seepage.
In order to make valve precision height, its profile of the spool that is adopted ［ 7 ］ can be the conical surface.
The said valve of the present invention can adopt stainless steel, copper, aluminum alloy and plastic or other material processing and fabricating.
The said valve of the present invention, its profile can be tubulose, spherical, streamline shape, also can adopt polygon-shaped.
Claims (4)
1, valve that constitutes by supplying tube [8], output tube [1] and valve body [A], it is characterized in that: valve body [A] is the opening/shutting mode of valve with respect to the rotation of supplying tube [8] and output tube [1], one of component part of valve body [A] is coil [5], valve body [A] is by valve core housing [6] the parallel connection inner with valve body [A] of the internal thread of coil [5], valve core housing [6] one ends are equipped with spool [7], and the other end is by only revolving pad [9] and the parallel connection of output tube [1].
2, valve according to claim 1 is characterized in that supplying tube ［ 8 ］ and output tube ［ 1 ］ that end in valve body ［ A ］ have boss.
3, valve according to claim 1, the profile that it is characterized in that only revolving pad ［ 9 ］ is a double polarizing keys shape.
4,, it is characterized in that ball ［ 3 ］ being set in the contacting point, the boss outside of valve body ［ A ］ and supplying tube ［ 8 ］, supplying tube ［ 1 ］ according to claim 1 and the described valve of claim 2.
