Abstract
The utility model provides a balance valve, belongs to the technical field valves, and solves the problems that a rotor plate and a stator plate generate mutual friction and are easy to thin due to abrasion, and the sealing performance between the rotor plate and the stator plate is greatly reduced in the opening, closing and adjusting process of an existing balance valve. The balance valve comprises a valve body provided with a water inlet cavity and a water outlet cavity, a valve core, a valve rod and a hand wheel. The inner end of the valve rod is connected with the valve core and can drive the valve core to rotate. The outer end of the valve rod extends out of the valve body and is connected with the hand wheel. A plurality of water passing holes communicated with the water inlet cavity and the water outlet cavity are formed in the valve body. Blocking sheets capable of blocking the water passing holes in the rotating process of the valve core are arranged on the valve core. An elastic mechanism which is capable of enabling the valve core to do axial motion along the valve rod and abuts against the water passing holes is arranged between the valve rod and the valve core. The valve core can axially move along the valve rod, and can be always tightly attached to the water passing holes of the valve under the action of the elastic mechanism. Therefore, the balance valve improves sealing effects and prolongs service life.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of equilibrium valve.
Background technique
The valve core structure complexity of equilibrium valve will be passed through multiple processing technology at present, and the cost height, causes man power and material's waste.People have invented simple valve core structure for this reason, as long as rotational valve core just can reach the effect of switch valve and regulating valve flow.
Change spool [patent No.: 201120416853.5] as a kind of water tap that Chinese patent is announced, comprise valve body, valve rod, and the ceramic moving plate and the ceramic stator that adjust aqueous mode, the pottery moving plate changes current water outlet direction by the fan-shaped water outlet that arranges in the bottom, and ceramic stator is provided with waist shape bypass channel and the fan-shaped water port of respectively corresponding two water outlets.Its adopts disjunctor design, and is simple in structure, easy to process, reduced the size error coefficient, and quality is more reliable, has also reached the purpose of saving cost.Owing to be not traditional rise-fall type spool, the friction factor of nitrile butadiene rubber reduces, and linking body structure has solved the spool bottom again and has been subjected to the effect of external force and causes the problem of being out of shape, rupturing, and makes spool work more stable, has prolonged its working life.But because the axial position of ceramic stator and ceramic moving plate fixes, all produce mutual friction at switch with when regulating, impaired and attenuation easily, this will cause sealing between the two to reduce greatly, and valve shortens working life greatly.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of equilibrium valve of good airproof performance.
The purpose of this utility model can realize by following technical proposal: a kind of equilibrium valve, comprise the valve body with water-inlet cavity and water chamber, spool, valve rod and handwheel, the inner of valve rod links to each other with spool and can drive valve core rotation, the outer end of valve rod is stretched out valve body and is linked to each other with handwheel, it is characterized in that, offer the water passage hole that several are communicated with water-inlet cavity and water chamber on the described valve body, have the catch that when valve core rotation, water passage hole can be blocked on the described spool, between described valve rod and spool, also be provided with and make spool be resisted against the elastic mechanism at water passage hole place along the valve rod axial motion.
Drive valve rod by the external handwheel of rotating valve and rotate, valve rod drives valve core rotation again, and the catch of spool is corresponding with the water passage hole on the valve body.When catch overlaps with water passage hole,, water passage hole is sealed by catch, and water-inlet cavity and water chamber are not communicated with, and valve is in closed condition; When catch and water passage hole staggered, valve was in open mode, and the flow of rotational valve core adjustable gate.Spool can move axially along valve rod, and elastic mechanism has spool to be resisted against the trend on the water passage hole, by the downward pressure of elastic mechanism spool is contacted with valve body and forms hard sealing.Although spool and valve body are because of the friction attenuation, elastic mechanism makes spool tightly be resisted against on the valve body all the time, has improved the sealing of valve, and has prolonged the working life of valve.
In above-mentioned equilibrium valve, described valve core housing is fixed on valve rod and circumferentially, and described water passage hole is fan-shaped and circumference array distributes, and described catch is all corresponding one by one with quantity and the position of water passage hole.Rotational valve core, all catch can overlap with water passage hole simultaneously one by one, and valve closing just can be realized opening and closing and regulating valve so rotate certain small angle.
In above-mentioned equilibrium valve, described catch is fan-shaped and cross-section area greater than the cross-section area of water passage hole.Catch is greater than water passage hole, can the complete closed water passage hole, and the fan-shaped catch water passage hole that can stagger fully, realize the maximum opening of valve.
In above-mentioned equilibrium valve, described elastic mechanism comprises the shoulder block that has on the spring that is enclosed within on the valve rod and the valve rod, and an end of spring is against on the spool, and the other end is resisted against on the shoulder block.Valve rod is axial restraint, and spool is subjected to the elastic force of spring and has the trend that moves down near water passage hole, be not subjected under the external force effect, and the catch of spool can be resisted against on the valve all the time, and sealing effect is better.
As another kind of scheme, in above-mentioned equilibrium valve, described elastic mechanism comprises the spring seat that has on the spool, be enclosed within the spring on the spring seat and be fixed on baffle plate on the valve rod, and described spring one end and spring seat lean, and the other end and baffle plate lean.Fixed dam on the valve rod, spring are located at the restriction that is subjected to spring seat in the spring seat, and spool is subjected to the elastic force of spring and has the trend that moves down near water passage hole, be not subjected under the external force effect, and the catch of spool can be resisted against on the valve all the time, and sealing effect is better.
In above-mentioned equilibrium valve, described baffle plate and valve rod are integral structure.Baffle plate and valve rod are integrally manufactured, sound construction.
As another kind of scheme, in above-mentioned equilibrium valve, offer annular groove on the described valve rod, be provided with clamp in the annular groove, baffle-plate-sleeve on valve rod and end face and clamp lean.Baffle-plate-sleeve is at valve rod, because baffle plate is subjected to the active force of spring to have the trend that moves up, sets firmly and puts clamp baffle plate is fixed, and baffle plate and valve rod are made respectively, and be easy to process.
Compared with prior art, this equilibrium valve has the following advantages:
1. valve core rotation throttle down, catch transversely cutting current, resistance coefficient is little during Shuttoff Valve, rational in infrastructure, regulation range is wide, control accuracy is high, easy to adjust.
2. spool can move axially along valve rod, is subjected to the elastic mechanism effect and is close to the water passage hole place of valve all the time, has improved the sealing effect of valve, improves working life.
