Abstract
Disclosed is a flow control valve, comprising a gland bush, a valve handle, a valve seat, a valve ball, a spring, a valve body and a rotary handwheel; wherein the spring, the valve ball and the valve seat are installed in the valve body in order from top to bottom; the valve seat is fixed on the inner wall of the valve body and the valve handle is connected with the gland bush through screw threads; the upper part of the valve body is connected with the gland bush through screw threads; the lower end of the valve handle stretches into the valve seat and contacts with the valve seat; the rotary handwheel is arranged on the valve handle. When opening the flow control valve, rotate the handwheel, then the valve handle will press the valve ball downwards, after that the valve ball separates from the valve seat and the flow passage will be opened. When closing the flow control valve, rotate the handwheel reversely, then the valve handle will move upwards and the valve ball restores under the effect of the spring and the flow passage will be blocked and the fluid is stopped from flowing. The valve ball and the valve seat are finished durable products, and the interface surface of the valve ball and the valve seat is a spherical face; therefore, the flow control valve is resistant to wear and is long in service life; the valve is of no need to be replaced frequently; the time for pipework production is enough, and manpower and material consumptions are less, thus the utility model is of good economic effect.
Description
One, technical field
The utility model is a kind of valve of controlling line fluid, and particularly a kind of flow control valve belongs to engineering goods.
Two, background technique
The valve that uses at present is gate valve, and in use front and back exist pressure difference, this pressure difference to cause that the flashboard thorn decreases, and cause the valve seepage, and valve is short working life, and often valve is changed in stopping production, increases Master Cost, consumes manpower, and economic loss is serious.
Three, summary of the invention
The purpose of this utility model is a kind of flow control valve of design, makes its anti-thorn decrease long service life.
The purpose of this utility model is to realize like this, form by gland, valve rod, valve seat, valve ball, spring, valve body, spring, valve ball, valve seat are installed in the valve body successively from bottom to up, valve seat is fixed on the valve interior wall, valve rod and gland scyewed joint, valve body top screw thread connects with gland, and stem lower portion stretches in the valve seat and with valve ball and contacts.
The beneficial effects of the utility model are: valve ball and valve seat are ripe durable products, and valve ball is that sphere contacts with the contact surface of valve seat, therefore, the anti-thorn of the utility model decreases, and long service life does not need often to change valve, the transfer line production time is many, and the consumption manpower and materials are few, good in economic efficiency.
Four, description of drawings
Accompanying drawing is an erection drawing of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is made up of gland 1, valve rod 2, valve seat 3, valve ball 4, spring 5, valve body 6, rotation handwheel 7.Spring 5, valve ball 4, valve seat 3 are installed in the valve body 6 successively from bottom to up, and valve seat 3 is fixed on valve body 6 inwalls, valve rod 2 and gland 1 scyewed joint, and valve body 6 top screw threads connect with gland 1, and valve rod 2 bottoms are stretched in the valve seat 3 and with valve ball 4 and are contacted.The handwheel 7 of rotation is arranged on the valve rod 2.During unlatching, rotate handwheel 7, valve rod 2 is to pressing down valve ball 4, and valve ball 4 lifts off a seat 3, and runner is opened, and fluid passes through.When closing, reversing handle, valve rod 2 rises, and valve ball 4 resets under the effect of spring 5, stops up runner, and fluid stops to flow.
