Abstract
The utility model relates to a quantitative adjusting valve. The utility model belongs to a flow capacity adjusting apparatus of which the inlet flow capacity is adjustable, and the utility model can be matched with all sorts of liquid pumps in use. The utility model is mainly used for solving the technical problem that the existing flow capacity adjusting apparatus has complex technology, high manufacturing cost, high price, inaccurate flow capacity adjustment and large controlling difficulty. In order to solve the problem, the utility model has the technical scheme that the quantitative adjusting valve comprises a valve body, a feed port, a discharge port, a gland, an adjusting screw, a handwheel and a locking nut, a cone-shaped adjusting valve core, a stuffing chamber, a sealing pad and a sealing gland, wherein the cone-shaped adjusting valve core is arranged on the other end of the adjusting screw and is arranged on the feed port. The stuffing room is arranged on the gland, and the sealing pad is arranged on one end of the stuffing room. The sealing gland is arranged on the stuffing room, and the sealing pad is tightly pressed against the end of the stuffing room.
Description
Technical field
The utility model relates to a kind of quantitative modulating valve, and it belongs to the flow regulator that a kind of inlet flow rate is adjustable and can be used with all kinds of liquid pumps.
Background technique
Mostly the metering pump that uses is to adopt off-centre, lever and other regulative mode to adjust the size of feed amount at present, though metering pump can be regulated flow, because its complex process, the manufacture cost height costs an arm and a leg, so application area is restricted.In addition, though existing Flow valve is low price, but because spool is a disc, the adjusting flow is inaccurate and the control difficulty is big, thereby existing flow regulator exists complex process, the manufacture cost height costs an arm and a leg and regulates the inaccurate and control difficulty big shortcoming of flow.
Summary of the invention
The purpose of this utility model is to solve existing flow regulator to exist complex process, the manufacture cost height costs an arm and a leg and regulates the inaccurate and big technological difficulties of control difficulty of flow and the quantitative modulating valve of a kind of that can be used with all kinds of liquid pumps, degree of regulation height, flexible operation, low cost of manufacture is provided.
The utility model is to address the above problem the technological scheme that adopts to be: quantitative modulating valve, it comprises a hollow valve body, end at valve body is provided with material feeding mouth, on the side surface of valve body, be provided with discharge port, the other end at valve body is provided with gland, adjusting screw rod is located at the central authorities of gland, handwheel is located at an end of adjusting screw rod and is fixed on the adjusting screw rod by locking nut, wherein: it also comprises the taper regulating spool, filler chamber, sealed pressure pad and sealing gland, the taper regulating spool is located at the other end of adjusting screw rod and is positioned at the material feeding mouth place, filler chamber is located on the gland, sealed pressure pad is contained in the end of filler chamber, and sealing gland is located in the filler chamber and sealed pressure pad is pressed on the end of filler chamber.
Because the utility model has adopted the taper regulating spool to make Flow-rate adjustment, the valve regulated scope is big, and therefore the degree of regulation height is compared with background technique, has advantages such as degree of regulation height, flexible operation, low cost of manufacture.The utility model can be used with the dissimilar liquid pump of all kinds of different mediums.
