Abstract
The utility model relates to the technical field of control valves, in particular to a manual throttle valve which is simple in structure, free of an additional control device and low in cost and comprises a shell and a valve plate.
Description
Technical Field
The utility model relates to the technical field of control valves, in particular to a manual throttle valve.
Background
The throttle valve is a valve for controlling the flow of fluid by changing the throttle section or the throttle length, has no flow negative feedback function, cannot compensate the speed instability caused by load change, and is generally only used in the occasions with small load change or low requirement on the speed stability.
At present, common throttle valves are controlled by a motor, the flow is adjusted by adjusting the opening angle of a valve plate, the structure is complex, and the cost is high.
Disclosure of Invention
In order to solve the problems of complex structure and high cost of the existing throttle valve, the utility model provides a manual throttle valve which is simple in structure, free of an additional control device and low in cost.
The technical scheme is as follows: the utility model provides a manual throttle valve, its includes casing and valve plate, its characterized in that, be provided with first through-hole in the casing, install the axle sleeve in the first through-hole, the counter bore has been seted up to the axle sleeve up end, the valve plate set up in the counter bore and connect and run through the valve rod one end of axle sleeve, the valve rod other end expose in the axle sleeve and with be provided with the spring between the axle sleeve, the second through-hole has been seted up on the valve plate, valve plate back mounted has the locating pin, set up on the axle sleeve at least two with the third through-hole that the second through-hole corresponds, at least two with locating pin complex pinhole, all the centre of a circle of third through-hole, the centre of a circle of pinhole are in same circle.
The shaft sleeve is further characterized in that the number of the third through holes is four, and the number of the pin holes is 8-10, wherein the pin holes are formed in one side of the shaft sleeve;
the spring is sleeved on the valve rod, one end of the spring abuts against the pressing head, and the other end of the spring abuts against the bottom of the shaft sleeve;
the first through hole is a step hole, a convex ring is arranged on the outer peripheral surface of the shaft sleeve, the convex ring of the shaft sleeve is in interference fit with the inner wall of the first through hole, and the bottom of the convex ring is supported on the step of the first through hole;
the inner diameter of the second through hole is smaller than that of the third through hole.
After the throttling valve is adopted, liquid or gas flows through the first through hole, the second through hole and the third through hole, the valve plate rotates to different positions, the position of the second through hole is changed, the area of the overlapped part of the second through hole and the third through hole is changed, the flow rate of the liquid or gas flowing through the valve plate is changed through the change of the area, the throttling effect is realized, the structure is simple, the valve plate can be rotated only by manually pressing the bottom of the valve rod to enable the positioning pin to be separated from the pin hole, the operation is simple, and the use cost is low.

Detailed Description
See fig. 1 and fig. 2, a manual throttle valve, which includes a housing 1 and a valve plate 2, a first through hole 3 is provided in the housing 1, a shaft sleeve 4 is installed in the first through hole 3, a counter bore 5 is provided on an upper end surface of the shaft sleeve 4, the valve plate 2 is disposed in the counter bore 5 and connected to one end of a valve rod 6 penetrating through the shaft sleeve 4, the other end of the valve rod 6 is exposed out of the shaft sleeve 4 and provided with a spring 7 between the valve rod and the shaft sleeve 4, a second through hole 8 is provided on the valve plate 2, a positioning pin 9 is installed on a back surface of the valve plate 2, four third through holes 10 corresponding to the second through holes 8 are provided on the shaft sleeve 4, nine pin holes 11 matched with the positioning pin 9 are provided, centers of all the third through holes 10 and centers of the pin holes 11 are located on the same circle.
In order to facilitate the installation of the spring 7, the bottom of the valve rod 6 is provided with a pressing head 12 with the outer diameter larger than that of the valve rod 6, the spring 7 is sleeved on the valve rod 6, one end of the spring abuts against the pressing head 12, and the other end of the spring abuts against the bottom of the shaft sleeve 4.
The first through hole 3 is a step hole, the outer peripheral surface of the shaft sleeve 4 is provided with a convex ring 13, the convex ring 13 of the shaft sleeve 4 is in interference fit with the inner wall of the first through hole 3, and the bottom of the convex ring is supported on the step of the first through hole 3, so that reliable fixation is realized.
For better control of the flow variation, the inner diameter of the second through hole 8 is smaller than the inner diameter of the third through hole 10.
The operation process is as follows: when the flow through the choke valve needs to be adjusted, press head 12 is pressed from the bottom upwards, break away from the pinhole on the axle sleeve 4 with the locating pin 9 of 2 bottoms of valve plate, then rotary valve rod 6 lets valve plate 2 follow and rotate, let locating pin 9 loosen press head 12 after aiming at other pinhole 11, under the effect of spring 7, valve plate 2 is down reset down and is let locating pin 9 insert in another pinhole 11, the position of second through-hole 8 changes simultaneously, make and third through-hole 10 overlap's area change, gas or liquid flow area's change has been realized, the effect of throttle has been reached.
