Abstract
The utility model relates to a rotary linear regulating valve. The utility model aims to provide a rotary linear regulating valve of simple structure, smooth channel and excellent regulating performance to solve the technical problem. The technical proposal for solving the problem is that the rotary linear regulating valve comprising a valve body, a valve core and a seal ring is characterized in that the valve core is arranged in the valve body, one end of the valve core is provided with a channel which is provided with an L-shape axis, the outlet height of the channel is corresponding to the outlet height which is arranged on the side wall of the valve body, and the seal ring is arranged on the valve core above the channel. The utility model is applicable to the situation for linear regulating a fluid flow rate.
Description
Technical field
The utility model relates to a kind of rotary linearly adjust valve.Be applicable to that fluid flow carries out the occasion of linearly adjust.
Background technique
Usually the valve that adopts in the occasion that needs fluid flow to carry out linearly adjust is ball valve, gate valve, needle-valve of various structures or the like, but exist to some extent all that complex structure, runner are unsmooth, the poor linearity of regulating or the like defective.As the patent No. is that the Chinese utility model patent that ZL91216277.5, name are called " flow control regulating valve " has related to the flow control regulating valve that the fluid passage is arranged in a kind of spool valve element with rotation entity sealing surface, and this technology has adopted to open down in the middle of the cylindrical valve spool and flowed chamber, sliding wall and offer groove and pass through conical surface pillow block mutually and reduce structure such as through-flow curvature.Be applicable in the manual flow control valve in liquid distribution, the transporting system.But this modulating valve exists complex structure, the rough deficiency of runner equally.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of simple in structure, runner is level and smooth, adjusting function is good rotary linearly adjust valve is provided.
The technological scheme that the utility model adopted is: rotary linearly adjust valve, comprise valve body, spool and seal ring, it is characterized in that described spool is installed in the valve body, end at spool has the L-shaped passage of axis, this passage go out open height with open on body wall to go out open height corresponding; On the spool above the described passage, seal ring is housed.
The outlet of the passage of described spool is shaped as rectangle, and the outlet shape on the corresponding with it valve body also is a rectangle.
The beneficial effects of the utility model are: when flowing through in the valve that the utility model relates to owing to fluid, only passed through spool, can not resemble ball valve, gate valve etc. and can flow through sealing material, groove etc., the fiber, particle etc. that can not take place in the fluid stick, collude extension, depositional phenomenon, and what guaranteed to flow is smooth and easy.Linearly adjust is functional, and along with the difference of the angle of swing of spool in valve body, the area of the common rectangle outlet that constitutes of spool and valve body will present linear change, thereby realizes the purpose of linearly adjust.Simple in structure, there are not too much component.

Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, present embodiment comprises valve body 1, spool 2 and seal ring 3, described spool 2 is installed in the valve body 1, has the L-shaped passage 2-1 of axis at an end of spool, this passage to go out open height highly corresponding with the outlet 1-1 that opens on valve body 1 sidewall; O-ring seals 3 is housed on the spool above the described passage 2.
The outlet of the passage 2-1 of this routine described spool is shaped as rectangle, and the outlet 1-1 on the corresponding with it valve body 1 also is a rectangle.The shape of outlet also can be selected circle or other shape as required.
Working procedure of the present utility model is: fluid is by the end face inlet passage 2-1 of spool 2, turning 90 degrees the back at the channel interior folding is flowed out through the outlet 1-1 of valve body 1 correspondence by the outlet of spool side, difference along with the angle of swing of spool in valve body, spool 2 will present linear change with the area of the valve body 1 common rectangle outlet that constitutes, thereby realizes the purpose of linearly adjust.
