Description
Technical field
The utility model belongs to valve technology field, is related to a kind of gate valve rod.
Background technique
Control valve is also known as valve, is the control unit in fluid delivery system, has water conservancy diversion, shuts off, adjusts, throttling, preventing
The only functions such as refluence, shunting or overflow release, can be used for controlling empty gas and water, steam, various aggressive chemistry media, mud, liquid
Various types of fluid activities such as state metal and radioactive substance, but usually there is leaked liquid in existing control gate valve, leads
It causes equipment to need to be replaced frequently, causes huge economic loss, we devise the anti-control that leaks of a novel one kind thus
Gate valve solves the problems, such as that a kind of traditional anti-control gate valve that leaks is inconvenient for use.
When in use, when closing control valve, sealing effect is poor for gate valve most at present；Such as the Chinese patent patent No.
Are as follows: a kind of pumping rod type gate valve described in " 02239528.8 ", specific structure include valve deck, valve body, valve rod, handwheel, flashboard,
Wherein valve rod one end is connected with handwheel fastening, and the valve rod other end is connected by screw thread and flashboard activity, and the big portion of valve rod and flashboard are equal
Be arranged in valve deck be connected to valve body it is intracavitary, in valve deck cavity wall have step, make valve deck can be divided into the epicoele being connected to up and down and under
Chamber has bulge loop on valve rod, and bulge loop is matched with valve deck epicoele, and clamp nut, compression spiral shell are equipped on the valve rod on bulge loop top
Mother is connected with valve deck epicoele outside screw, and the valve rod of bulge loop lower part is matched with valve deck cavity of resorption.
In such a configuration, one end of the valve rod is threaded through in valve body, and the other end of valve rod is living by screw thread and flashboard
Dynamic to be connected, flashboard sealing corresponding with valve body, the valve rod concentricity is lower, for a long time in use, valve rod is prone to wear and then leads
Situations such as causing flashboard to cooperate with valve body not tight, being easy to cause valve body internal leakage generation；Once there is eccentric wear on valve rod and be somebody's turn to do
Make the ring wear of bulge loop two sides, sealing effect is poor between valve rod and valve body, infiltration is easy, so that the use of product entirety
Service life can also shorten accordingly.
Summary of the invention
